Abstract. Dependable flow rate measurements are necessary to calculate flow volumes and resulting nutrient loads from subsurface drainage systems and associated conservation practices. The objectives of this study were (1) to develop appropriate weir equations for a new stainless steel-edged 45° V-notch weir developed for AgriDrain inline water level control structures and (2) to determine if the equation was independent of flow depth in the structure. Weirs for 15 cm (6 in.) and 25 cm (10 in.) inline water level control structures were placed at three heights in each structure: at the base, 48 cm from the base, or 97 cm from the base, and the height of the nappe above the weir crest was recorded over a range of flow rates. The resulting data were fitted to equations of the form Q = aHb where Q is the flow rate, H is the height of the nappe above the weir crest, and a and b are fitted parameters. There were no significant differences in the fitted parameters across the two structure sizes or across the three weir placements. The fitted equation for these new stainless steel-edged V-notch weirs was Q = 0.011H2.28 with Q in liters per second and H in centimeters, and Q = 1.44H2.28, with Q in gallons per minute and H in inches. These equations can be used for measuring flow through AgriDrain in-line structures, although in-house weir calibration is highly recommended for specific applications, when possible. Keywords: Drainage, Flow monitoring, Subsurface drainage, V-notch weir, Weir calibration.

Impact wear of mild steel has been studied in light of impact angle reversal. An in-house built, specially designed test rig has been used to facilitate test conditions, including impact angle reversal. Metallographic examination and scanning electron microscopy were used to analyze the morphology of impact surfaces. Results showed lower impact wear under condition involving impact angle reversal for the whole range of impact angles. Furthermore, multiple impact direction reversal showed significant impact wear reduction. Behavior has been explained in terms of failure due to plastic deformation accumulation.

The 25 April 2015 Nepal earthquake of magnitude 7.8 epicentre at Gorkha and magnitude 7.3 aftershocks on 12 May epicentre at Dolakha had devastating impacts on 14 districts including Kathmandu, capital city of Nepal. Death toll was nearly 9,000 and hundreds of thousands of inhabitants became homeless. The earthquake severely damaged mainly surface structures of hydro projects, access roads, clay mortar stone masonry houses and structurally weak concrete houses. Landslides, rock falls, debris flow, liquefaction, river damming, Landslides Dammed Outburst Flood (LDOF) and Glacial Lake Outburst Flood (GLOF) are expected earthquake-induced hazards. However, landslides and grounds shaking were responsible for major damaged. A total of 15 hydro projects in operations and under construction were affected by the earthquake. In hydro projects damages were recorded in surface structures such as power house, settling basin, penstock pipes, and diversion weir constructed at base of steep terrains. For instance, surface penstock pipe, lying at base of rock cliff, of running 40 MW Upper Bhote Koshi Project was ruptured by rock falls and as a result flooded surface powerhouse located downstream by water from penstock and headrace tunnel. Similarly, diversion weir, surface settling basin and headrace penstock pipe of running 5 MW Mialung Project were also severely damaged by slides and rock falls. On the other hand, only minor cracking of sprayed concrete at corners and protruded edges in underground structures were observed. In hydro projects, there is a practice of considering seismic load in design of structures but the effects of earthquake induced hazards were not foreseen. This devastating earthquake gave good lessons for design considerations of hydro projects in future. This article summarises earthquake damage, risks and lessons learned for Hydro projects in Nepal.

The results of tribological investigations into the lubrication efficiency of greases in steel sliding pairs working in mixed friction conditions are presented. The lubrication efficiency was evaluated according to the criterion of wear determined by tribological tests conducted at variable values of motion parameters: load F and sliding velocity v. Wear volume VF(d), calculated from wear regression equations (wear d = f(p,v), was adopted as the lubrication efficiency criterion. Five different commercial greases currently available on the market and one in-house grease (a compound of grease 1S and two solid greases (6% PTFE and 5% Cu)) were tested. The experiment was conducted in a four-ball tester at five levels in accordance with the rotatable experiment design. A regression function with interrelated ball wear d, sliding velocity v, and applied load F, was formulated for each of the tested greases. Wear volumes VF(d) were calculated and conclusions were drawn.

Purpose – This paper aims to deal with the study of effect of cerium oxide (CeO2) modification on the sand slurry erosion resistance of Ni – tungsten carbide (WC) coatings. Design/methodology/approach – Flame-sprayed conventional and CeO2-modified Ni–WC coatings were developed on a mild steel substrate. Slurry erosion tests were carried out in an in-house-designed and fabricated pot-type slurry erosion test rig to evaluate wear behavior of conventional and modified coatings. The erosive wear test was conducted using 5 per cent silica sand slurry at 850 rpm. Findings – Modified coatings exhibited increased hardness as compared to the conventional coating. Slurry erosion resistance of most modified coatings was superior to that of the unmodified coating. Hardness of coating doped with 0.9 per cent CeO2 was highest among all coatings, and concomitantly this composition also showed the least wear. Scanning electron microscopy (SEM) revealed that microcutting was much less in the modified coating. Originality/value – Slurry erosion wear of Ni–WC flame-sprayed coatings in sand slurry media is substantiated by extensive SEM study.

CR is often used to make the foreskin material transport belts, wires, cables, and the manufacture of oil hose, gaskets, equipment and chemical resistant bushing. EPDM is often used to produce heat-resistant conveyor belts, cables, wires, anti-corrosion lining, gaskets, waterproof sheet, door and window seals, etc. The same hardness and different proportions of CR/EPDM blends with steel under dry friction pair as the research object to seek friction characteristics of different formulations of rubber with steel metal in the dynamic coordination. Friction test at a constant low load, constant temperature, the different mixing ratio of CR/EPDM blends, friction, wear, friction coefficient variation with engine speed. The test results to a reasonable choice of conveyor belts to improve the overall efficiency and life of rubber - metal friction pairs.

The rate of heat extraction during the pressure die casting process is central to both the quality and the cost of finished castings. Recent efforts to reduce the thermal resistance of dies by optimizing the effectiveness of the cooling channels have shown the potential for improvement. Reducing the thermal resistance of the coolant boundary layer means that a significant proportion of the total thermal resistance becomes attributable to the die steel. Further significant reductions in die thermal resistance can be obtained by replacing the steel with copper. This paper investigates the feasibility of using copper dies, reinforced with steel inserts and coated with a thin layer of wear resistant material, which is deposited using the thermal arc spray process. Experimental work relating to the thermal spray process has been undertaken to establish bond strengths and thermal conductivities for various process parameters. Moreover, experimental investigations have been carried out using two copper coated dies, the first of which was a pseudodie block heated by an infrared heater. The second die was tested on a die casting machine and produced zinc alloy castings at a greatly increased production rate when compared to its steel counterpart. The experimental results from the two dies are compared with those predicted by an in-house thermal-cum-stress model based on the boundary element method. Reasonable agreement between the predicted and experimental results is shown and the feasibility of copper-alloyed dies for pressure die casting is established.

Tungsten carbide cutting tools with and without solid lubricant (WC-10Co-5CaF2 and WC-10Co) were developed in-house via powder metallurgy. The developed cutting tools and a commercial WC-10Co cutting tool were used to machine cylindrical AISI 1020 steel material under dry conditions. The cutting force and average cutting tool temperature were continuously measured. The cutting tool flank surface and chip morphology after specific tool life (5 min of cutting) were examined to understand tool wear. The flank wear of the considered cutting tools was also measured to quantify the cutting tool life. The surface roughness of the workpiece was measured to determine the machining quality. The developed cutting tool with solid lubricant (WC-10Co-5CaF2) generated 20%–40% less cutting force compared to that of the developed cutting tool without solid lubricant (WC-10Co). In addition, the finish of the workpiece surface improved by 16%–20% when it was machined by the solid lubricant cutting tool. The cutting tool with solid lubricant (WC-10Co-5CaF2) exhibited a 15%–18% reduction in flank wear. Curlier and smaller saw tooth chips were generated from the WC-10Co-5CaF2 cutting tool, confirming that less heat was generated during the cutting process, and the finish of the machined surface was also improved.

The wide use of conventional lubricants causes pollution to the environment and the rising awareness on green house effect has triggered the use of environmental friendly and biodegradable lubricants in the industries. Palm olein was selected to be a candidate due to its superior tribological properties and large production in country. In the research, the behavior of palm olein characteristic was investigated by using pin-on-disk experiment in which the pin was loaded against the rotating grooved disk. The experiments by sliding were performed via pin on disk tester using stainless steel as the material for both flat ended pin and grooved disk. The test were carried out by dropping 5 ml of palm olein as lubricant on the sliding surface at two different speeds which were 0.25 and 1 m/s. In this study, the wear rate of the pin and friction coefficient was investigated. The weight loss and surface roughness before and after experiment were analyzed. All the results obtained were compared to hydraulic oil and paraffinic mineral oil. From the analysis, friction coefficient acquired with lubrication of palm olein was the lowest for both conditions, while the wear rate obtained also showed a similar trend. The pin lubricated with palm show the lowest result of wear rate and weight loss.

AbstractImpact is considered the most critical part of the stance phase for the development of chronic articular disorders such as osteoarthritis in the equine distal limb. Modern, synthetic shoeing materials are believed to modify impact and therefore are often used to treat an/r prevent lameness due to chronic joint disorders. Scientific evidence is scarce, however, to prove this. Hoof impact of forelimb was compared quantitatively in a group of horses under three conditions: unshod, classical steel shoes and shod with a synthetic shoe. Twelve sound warmblood horses were trotted by hand on an asphalt track at a mean speed of 3.5ms−1 and measured in a Latin square design (unshod condition, with steel shoes and with polyurethane (PU) shoes) using a triaxial accelerometer that had been fixed to the lateral hoof wall of the left forelimb. The sampling frequency was set at 10kHz per channel. The maximum amplitude of vertical and horizontal, forwar/ackward accelerations at hoof impact was lowest when shod using the PU shoeing condition (P<0.05), but the duration of the impact vibrations was lowest when unshod. PU shoes cause more damping, less friction and slower shock absorption at hoof level compared with the other two conditions and thus modify impact. Synthetic, polyurethane shoes may help in reducing peak vibrations. These short-term effects appear to be promising enough to evaluate PU shoes under field conditions in reducing impact on the longer term after substantial wear and tear. Furthermore, the possible role of synthetic materials in repairing critical tissues or even in preventing osteoarthritis in horses warrants further investigation.

Austenitic stainless steels have received much attention in recent years due to their excellent combination of corrosion, mechanical and wear properties. They are finding wide applications in chemical, power, oil, refinery, biomedical, marine sectors and other industries where both good mechanical properties and excellent corrosion and wear resistances are demanded. In the spent nuclear fuel reprocessing plants and waste storage and processing plants involving nitric acid as the main process medium, type 304L stainless steels (SS) are employed as work horse materials for manufacturing more than 90% of the plant components. Though these alloys form a protective Cr2O3 passive film over the surface in nitric acid under plant operating conditions, they undergo various types of corrosion failures in service. Welding and other metallurgical parameters including alloying elements, cold working, heat treatment etc. degrade the performance of the alloy in service. For qualifying the alloy for plant applications, ASTM A262 practice A and C are currently employed, however, long term performance under simulated plant operating conditions is necessary to understand the failure modes and life prediction of components. Today, nitrogen represents an economically, environmentally, attractive and versatile alloying element to steels and stainless steels. The beneficial effect of nitrogen alloying in stainless steels are manifolds, including solid solution strengthening, precipitation effects, phase control and corrosion and wear resistances. Recent years have seen a rapid development of these alloys with improved properties owing to advances in alloy processing technologies. The objective of the lecture is to bring out the various corrosion issues in reprocessing plants, short term laboratory versus long term field corrosion data, modeling for life prediction, effect of redox ions, nitrogen alloying, welding and corrosion damage, etc. and highlight the remedial actions to overcome the shortcomings due to corrosion issues.

Hole quality in drilling is considered a precursor for reliable and secure component assembly, ensuring product integrity and functioning service life. This paper aims to evaluate the influence of the key process parameters on drilling performance. A series of drilling tests with new TiN-coated high speed steel (HSS) bits are performed, while thrust force and torque are measured with the aid of an in-house built force dynamometer. The effect of process mechanics on hole quality, e.g., dimensional accuracy, burr formation, surface finish, is evaluated in relation to drill-bit wear and chip formation mechanism. Experimental results indicate that the feedrate which dictates the uncut chip thickness and material removal rate is the most dominant factor, significantly impacting force and hole quality. For a given spindle speed range, maximum increase of axial force and torque is 44.94% and 47.65%, respectively, when feedrate increases from 0.04 mm/rev to 0.08 mm/rev. Stable, jerk-free cutting at feedrate of as low as 0.04 mm/rev is shown to result in hole dimensional error of less than 2%. A low feedrate along with high spindle speed may be preferred. The underlying tool wear mechanism and progression needs to be taken into account when drilling a large number of holes. The findings of the paper clearly signify the importance and choice of drilling parameters and provide guidelines for manufacturing industries to enhance a part’s dimensional integrity and productivity.

Short fibre reinforced thermoplastics are being considered for light- and medium-duty engineering applications because of their improved mechanical strength combined with cost-effective advantages. In recent years, the carbon nanotube reinforced thermoplastics are being preferred over the short fibre reinforced thermoplastics because of the absence of directional shrinkage characteristics, directional mechanical and tribological properties. In this work, 1 wt% carbon nanotube–polypropylene material was injection-moulded to spur gears and evaluated for the durability using in-house developed power absorption gear test rig. During testing, the net surface temperature of the test gears and in-line torque available at the driver and driven shafts were continuously measured. The measured torque was used to evaluate the transmission efficiency of the test-steel gear pair. The measured net surface temperature was correlated with the gear failure mode. Test gears were run up to failure or up to 8.6 × 105 cycles, whichever occurred first. Worn-out gear tooth surfaces were observed using an optical and scanning electron microscope to understand the wear mechanism. In the initial stage of service, test gears exhibited less wear near the pitch region compared to the tip and root regions. This behaviour is due to the maximum sliding velocities at the tip and root regions compared to the pitch region. The carbon nanotube–polypropylene gears exhibited lower surface temperature (5−10 ℃), improved service life (30%−80%) and higher transmission efficiency (1−1.5%) compared to the polypropylene gear.

Horse racing is a multi-billion-dollar industry that has raised welfare concerns due to injured and euthanized animals. Whilst the cause of musculoskeletal injuries that lead to horse morbidity and mortality is multifactorial, pre-existing pathologies, increased speeds and substrate of the racecourse are likely contributors to foot disease. Horse hooves have the ability to naturally deform during locomotion and dissipate locomotor stresses, yet farriery approaches are utilised to increase performance and protect hooves from wear. Previous studies have assessed the effect of different shoe designs on locomotor performance; however, no biomechanical study has hitherto measured the effect of horseshoes on the stresses of the foot skeletonin vivo. This preliminary study introduces a novel methodology combining three-dimensional data from biplanar radiography with inverse dynamics methods and finite element analysis (FEA) to evaluate the effect of a stainless steel shoe on the function of a Thoroughbred horse’s forefoot during walking. Our preliminary results suggest that the stainless steel shoe shifts craniocaudal, mediolateral and vertical GRFs at mid-stance. We document a similar pattern of flexion-extension in the PIP (pastern) and DIP (coffin) joints between the unshod and shod conditions, with slight variation in rotation angles throughout the stance phase. For both conditions, the PIP and DIP joints begin in a flexed posture and extend over the entire stance phase. At mid-stance, small differences in joint angle are observed in the PIP joint, with the shod condition being more extended than the unshod horse, whereas the DIP joint is extended more in the unshod than the shod condition. We also document that the DIP joint extends more than the PIP after mid-stance and until the end of the stance in both conditions. Our FEA analysis, conducted solely on the bones, shows increased von Mises and Maximum principal stresses on the forefoot phalanges in the shod condition at mid-stance, consistent with the tentative conclusion that a steel shoe might increase mechanical loading. However, because of our limited sample size none of these apparent differences have been tested for statistical significance. Our preliminary study illustrates how the shoe may influence the dynamics and mechanics of a Thoroughbred horse’s forefoot during slow walking, but more research is needed to quantify the effect of the shoe on the equine forefoot during the whole stance phase, at faster speeds/gaits and with more individuals as well as with a similar focus on the hind feet. We anticipate that our preliminary analysis using advanced methodological approaches will pave the way for new directions in research on the form/function relationship of the equine foot, with the ultimate goal to minimise foot injuries and improve animal health and welfare.

The article considers the problems of ship structures exposed to adverse conditions, which contribute to the failure of important mechanisms and reduce the service life of steel parts of machines. One of the most important reasons for the ship structures wear is corrosion. The experience of choosing the electrodes to control the sacrificial protection systems on board ships is presented. There are presented the results of measuring the potential of the hull of the boat ROOM 52-22 at a given control point, using a multimeter MASTECH MY 62 and two control electrodes. The first control electrode is of in-house design; it was made of electric carbon product for electric machines. A standard portable silver chloride reference electrode was used as a second electrode. Both electrodes have been in operation for 3 years. The vessel under consideration was in a long-term parking mode. Control measurements were performed from 23.05 - 07.07.2019, while monitoring the potential of the hull three times a day using several parallel measurements. The time interval between parallel potential measurements made ≈ 5 seconds. The potential of the hull was measured by a specially trained operator. The accuracy of measurements was estimated using the coefficient of variation. Analysis of the studies justified that the accuracy of the control results of the protective anticorrosion systems on ships depends on the choice of the type of control electrode. It has been found that the efficiency of the silver chloride electrode has a strong impact on its operation life. The results of full-scale corrosion studies can be used by ship crews to justify the selection of control electrodes.

This research presents performance of nitrogen gas as a coolant in machining titanium. Compressed nitrogen gas stored in a cylindrical tank is supplied to the cutting zone via the stainless steel tube of 2x8x25mm (inside diameter x outside diameter x length) connected to the flexible hose and specially-designed valve with pressure controller. Machining experiments are carried out on conventional turning center. The cutting tool used is triangular insert of ISO-TPGN160308 with the holder (ISO-CTGPR3232K). The cutting insert grade is KC5010 (TiAlN3 coated carbide) as recommended by Kennametal for machining titanium. During machining, the tube is manually directed to be just-above the tool rake face and the nitrogen gas is supplied with high pressure so that the cutting zone receives an effective cooling as well as the chip brakes easily. The effectiveness of this new cooling strategy is demonstrated by the cutting edge condition and surface finish after machining at various speeds, and also by comparing with performance of conventional coolant. The result is found to be excellent in terms of relative amount of tool wear and surface finish. The cutting insert has surprisingly remained almost intact when using nitrogen gas coolant whereas severe tool wear occurred with conventional coolant even at low cutting speed. This cryogenic strategy also improved machined surface quality greatly.

Abstract Nuclear waste sites across the United States and other countries store, transfer and vitrify nuclear waste. These sites often require transfer pipelines for high and low level radioactive wastes in the form of solids/slurries, fluids including chemicals. Since, these pipelines deal with harmful nuclear wastes, structural health monitoring is of utmost importance. Pipelines are continuously monitored to enhance the safety of the people and environment around the facilities. Monitoring may involve leak, crack detection and wear (in the form of corrosion or thinning). Current research builds on author's previous work on sensors for erosion and thermal monitoring in pipes and plates [1, 2, and 3]. Present work involves a) validation and monitoring of a novel advanced Fiber Optic Sensor System to detect cracks and leaks in carbon steel pipes and b) the use of Ultrasonic (UT) sensors to detect thinning in pipe sections due to erosion-corrosion using small coupons. The fiber optic sensors developed by CEL [4], are used in conducting engineering scale testing on an in-house designed and assembled erosion pipe flow loop. The loop consists of 2 and 3 inch straight and elbow sections of carbon steel replicating the pipelines at the sites. Three fiber optic sensors are placed at critical locations around the loop. The equipment also includes a communication box and a laptop device for data acquisition. The sensor system uses a combination of fiber optic and acoustic technologies to accurately identify the location of a pipeline leak or crack. Sensors capture the changes in pressure caused by the fluid/slurry flowing through the loop. A “zone” is defined as the distance between any two sensor points. When any two sensors simultaneously detect a leak, a determination can be made as to how far from each sensor the activity is occurring and “zero in” on the event. A number of zones may be linked together to manage vast expanses of pipeline. Sensors provide instantaneous event data to the hardware (the interrogator), and the interrogator may be located great distances from the actual pipeline in secure, environmentally protected areas. Multiple Interrogators may be linked together that are simultaneously streaming real-time data to the command and control software. Event notifications may then be managed from the customer's control room, or immediately “pushed” to a variety of mobile devices to alert personnel of the situation [5]. Additionally, Ultrasonic (UT) sensors are used for thickness measurements in pipes. The objective is to measure the wear in pipelines due to erosion-corrosion using small scale erosion coupons. These erosion coupons are made of carbon steel with ½ inch in diameter and 1 inch height. The method involves insertion of the coupons into holes drilled in the pipe sections of the erosion loop. This process ensures that the coupons are in contact with the flow stream and hence eroded in a minute scale over a period of time. The coupons have a slot for insertion of the sensors to measure the thickness in real-time when needed. Upon successful testing of the coupon and sensors, the method can be used to predict the erosion rates and hence the remaining useful life of the pipe sections without having to replace them unnecessarily. Hence, the present research conducts structural health monitoring of carbon steel pipes using fiber optic and UT sensors. The sensors have been validated and verified for their potential future deployment in the nuclear waste sites.

This summary report is based on the experimental and numerical research of thin-walled cross-section’s compression resistance and shear strength of their joints carried out in St. Petersburg State Polytechnical University and HAMK University of Applied Sciences, Sheet Metal Centre. Current situation on Russian market concerning the usage of cold-formed thin-walled cross-sections is aimed to find out a base foundation to start up a stipulation of the elements under discussion in the building industry (Kolesov et al. 2007; Peleshko, Urchenko 2009; Zhmarin 2012). Some questions about the compression resistance of such cross-sections were raised on different conferences (Vatin, Sinelnikov 2013; Winter 1952; Yu Wei-Wen et al. 1996) by scientific community and by companies such as Rautaruukki Oyj (Finland). Steel galvanized C-and U-profiles and thermo-profiles are types of thin-walled cross-sections that are normally used in small houses construction (Shatov 2011; Smaznov 2011). Thermo-profiles have slots in web that decrease the thermal flow through the web, but have a negative effect on strength of the profiles (Schafer, Pekoz 1998; Vatin, Popova 2006). These profiles were an object of the research. Investigations carried out included tests to prove the compression resistance of the thin-walled cross-sections and shear strength of stud-to-rack joints. Numerical modelling of thin-walled cross-sections (Cheng, Schafer 2007) was done with contemporary analysis software (SCAD Office, Lira) (Kriksunov et al. 2010; Perel'muter et al. 2009) using the finite element method (FEM) (Bayan et al. 2011; Gordeeva, Vatin 2011; Rasmussen 2009).

Abstract Storage tanks and pipelines are used at nuclear waste sites across the Department of Energy (DOE) complex to store and transfer nuclear wastes. One of the significant aspects in such sites is monitoring the structural integrity of the waste transfer pipelines and the storage tanks. Literature indicates that the industry standard method of thickness measurements using ultrasonic sensors is mainly through manual inspections. As such, this procedure is expensive and exhaustive for nuclear applications. Hence, in this research, the authors assess a wave guided ultrasonic sensor system for erosion-corrosion (thickness change) detection in waste transfer pipelines at Hanford nuclear waste site. This ultrasonic transducer (UT) sensor system (from Permasense, a UK based manufacturer [2]) has the advantage of real-time remote monitoring. It is an integrated wireless sensor network system which uses a patented technology for the acoustic wave propagation and has proven applications in the oil and gas industries [3]. This UT sensor system meets the requirement of providing the actual thickness measurement in pipes, is capable for 2 inch pipes and elbows, and is customized for mounting with a mechanical clamping system. The sensors are also capable of operating at high temperatures up to 600°C (1100°F). This is due to their patented waveguide technology that holds the sensor head (containing ultrasonic transducers, electronics, and battery) away from the hot metal surface. The sensor's measurements are transmitted wirelessly back to a gateway (wireless access point) mounted near the main unit. Since there is no cost associated with measurement acquisition or measurement retrieval, the frequency of measurement can be configured to be as frequent as every 15 minutes. Connection of the gateway to the operator's existing information technology infrastructure allows the data to be viewed from personnel desks. Sensor battery life of up to 10 years allows continuous data delivery between turnarounds without access to a sensor's physical location. The sensor model chosen for the present research (testing and validation) is the WT 210 series [2]. It consists of the 304 stainless steel wave guides, sensor head, antenna, battery and a stabilizer. In addition there is a built in thermocouple probe to monitor the pipe surface temperature which also allows the wall thickness measurement to be temperature compensated when required. The sensors communicate using a customized wireless protocol, creating a self-forming and self-managing wireless mesh, which delivers continuous wall thickness measurements of the highest integrity and accuracy directly to the end user. Scope of the present research includes the initial verification and validation of the Permasense Guided Wave sensor system as a potential erosion/corrosion detection system for carbon steel pipelines under static conditions. The real-time erosion/corrosion detection is also investigated by measuring the thinning of the pipe sections by circulating simulants and continuous monitoring. This is achieved by passing abrasive solutions through an in-house designed pipe loop system. The loop has been designed to replicate the sections and carbon steel pipe material similar to the existing system at Hanford site. Varying concentrations of sand and water mixture is used as an eroding agent [5]. The erosion experiments are conducted for several months and the results obtained provide realistic wear rates on 2 inch and 3 inch carbon steel pipes with straight sections and elbows using the Permasense UT sensor system. Thus, the present research delivers solutions for sensor evaluations and conducts bench scale testing followed by data acquisition and analysis for corrosion and erosion assessment. This assessment of the UT sensor system will be useful for monitoring the real-time thinning of the waste transfer pipelines and to deliver more realistic estimates of the remaining useful life of the components and incorporate those estimates into future design/testing plans across the nuclear waste sites.

AbstractThis study utilises a recently developed, enhanced approach to assess detailed aspects of the corrosive wear behaviour of different steel grades in aqueous slurries containing three NaCl concentrations (0.05%NaCl, 3.5%NaCl and 10%NaCl). Erosion-corrosion testing was conducted using a slurry impingement test rig and damage was quantified using volume loss, potentiodynamic polarisation scans and surface topography. Single- and segmented specimens were adopted to yield the contribution of the degradation mechanisms in the two hydrodynamic zones (directly impinged and surrounding area). The overall material losses from the two zones of the stainless steels were observed to increase with increasing salinity. However, the overall material loss for the low-alloy steel was found to increase from 0.05%NaCl to 3.5%NaCl, before reducing when the salinity was further increased to 10%NaCl. Changes in salinity were observed to have the most effect on the corrosion-enhanced mechanical damage mechanism. The in-house developed technique demonstrated good linkage between single samples and the outer area damage region. However, it also showed that the use of single samples can be less successful when assessing highly turbulent (directly impinged) damage regions.

In industry, thermally shocked components lead to early failures and unexpected breakdowns during production resulting in huge losses in profit. Thus, the present study investigates the as-received, hardened and hardened and nitrogen treated H13 tool steels subjected to a thermal shock gradient similar to the actual industrial applications. The thermal shock gradients were created by using an in-house-built thermal shock fatigue cyclic treatment machine. The effect of thermal shock fatigue cyclic treatments at 1000 and 2000 thermal shock cycles in hot and molten metal chambers was noticed. All the thermal shock fatigue cyclic-treated samples were analysed by hardness, X-ray diffraction, microscopy and magnetic tests. The interesting changes in hardness, distorted crystal structure and crack initiation were found to be different for differently treated H13 tool steel specimens. The molten aluminium was more prone to stick to the surface of as-received as well as hardened and nitrogen treated steel compared to the hardened H13 steel specimens, which would delay the crack initiation. The wear resistance properties of the hardened H13 steel specimens were found to be higher than as-received and hardened and nitrogen treated H13 steel specimens after thermal shock fatigue cyclic treatment. The loss in magnetic properties was significant for the hardened and hardened and nitrogen treated samples compared to as-received H13 tool steel specimens. Therefore, the present 1000 and 2000 thermal fatigue cycles for 30 s at 670 °C would be worthy to predict the proper heat treatment method to design the parameters as well as the life of die-casting components and to help in the economical production of casting.

Kata kunci: Gerudi KLT, KEI, mekanisme haus, rekatan, haba In this study, High Speed Steel (HSS) twist drills were investigated for mechanical wear by performing drilling test on the work piece of mild steel plate. TiN coatings onto the HSS twist drills were achieved by employing reactive radio frequency (r.f) magnetron sputtering technique, which was developed in–house. The drilling performance tests were set at a rotation speed of 1,600 rpm, feed rate of 20 mm/min, and depth of cut of 25 mm. The morphological changes of the wear surface were observed using Scanning Electron Microscopy (SEM). Results of morphological examination showed that the failure mechanisms in operation during drilling were found to be adhesive and thermal wear mechanism. This paper will also discuss explicitly the processes of adhesive and thermal wear mechanism generated during drilling of twist drill on mild steel plate. Results of drilling performance test showed that the TiN coating deposited on the HSS twist drill had improved drill life by more than 2 times as compared with uncoated drill. Key words: HSS drill, SEM, wear mechanism, adhesive, thermal

Advanced high strength steels have excellent strength-to-weight ratio and are widely used for automotive and structural applications. Grinding is commonly used as a final machining process for these materials to achieve the required dimensional tolerance and surface quality. In this work, the grindability of as-received microstructure of ferrite-pearlite and in-house developed ferrite-bainite-martensite steels using polycrystalline white fused alumina and microcrystalline sol-gel alumina grinding wheels under flood and minimum quantity lubrication conditions is studied. Grindability of these steels was evaluated based on the wheel wear, grinding forces, force ratio, specific cutting energy, surface roughness (Ra), and surface morphology. The sol-gel alumina wheel was observed with higher wear flat area and forces under all the grinding conditions as compared with white fused alumina wheel. The white fused alumina wheel exhibited higher force ratio values for all the grinding conditions than the sol-gel alumina wheel. The energy required per unit volume of material removal is lower for the white fused alumina wheel in both the steels under flood and minimum quantity lubrication conditions. This is due to the retention of sharpness of abrasive grains by self-sharpening for white fused alumina wheel than the sol-gel alumina. The presence of fractured, melted, and hollow chips on the ferrite-pearlite and ferrite-bainite-martensite steels under both the grinding condition confirms the change in material removal mechanism with the presence of higher wear flat area of the sol-gel alumina wheel. Based on the obtained results, the white fused alumina wheel was found to be a suitable grinding wheel for grinding of both the steels under all grinding conditions compared to the sol-gel alumina wheel.

The goal of this work is to design and build a vibration test bench to simulate unbalance in rotating machine. The vibration test bench made of a 25 mm diameter steel shaft and length of 410 mm supported by two ball bearings. Two steel discs to variate unbalance load installed in the shaft powered by 0.5 Hp electric motor with maximum rotation of 1400 RPM. Inverter used to control rotation from electric motor. Vibration testing conducted at two condition; (1) without load and rotation variation, (2) unbalance load with variation of unbalance mass. Pick up point of vibration measurement at bearing house in radial and axial direction. The vibration parameter measured are amplitude and spectrum (wave form). Amplitude measurement using hand held vibrometer, while spectrum using accelerometer conected to a Data Acquisition. After testing the condition using unbalance load, we conclude that the vibration test bench match unbalance condition as described in theory which is high amplitude at machine frequency, and it’s value proportional to unbalance mass. We find that the highest amplitude is at horizontal direction where machine stiffnes is smallest. Vibration testing with no load condition show that there is harmonic in vibration spectrum indicating rotating looseness, probably caused by bearing wear.

0. IntroductionIf we follow the line of much literature surrounding airports and urban mobility, the emphasis often falls on the fact that these spaces are designed to handle the mega-scale and super-human pace of mass transit. Airports have rightly been associated with velocity, as zones of rapid movement managed by enormous processing systems that guide bodies and things in transit (Pascoe; Pearman; Koolhaas; Gordon; Fuller & Harley). Yet this emphasis tends to ignore the spectrum of tempos and flows that are at play in airport terminals — from stillness to the much exalted hyper-rapidity of mobilized publics in the go-go world of commercial aviation.In this photo essay I'd like to pull a different thread and ask whether it's possible to think of aeromobility in terms of “uneven, differential mobility” (Bissell 280). What would it mean to consider waiting and stillness as forms of bodily engagement operating over a number of different scales and temporalities of movement and anticipation, without privileging speed over stillness? Instead of thinking mobility and stillness as diametrically opposed, can we instead conceive of them as occupying a number of different spatio-temporal registers in a dynamic range of mobility? The following is a provisional "visual ethnography" constructed from photographs of air terminal light boxes I have taken over the last five years (in Amsterdam, London, Chicago, Frankfurt, and Miami). Arranged into a "taxonomy of differentiality", each of these images comes from a slightly different angle, mode or directionality. Each view of these still images displayed in billboard-scale light-emitting devices suggests that there are multiple dimensions of visuality and bodily experience at play in these image-objects. The airport is characterized by an abundance of what appears to be empty space. This may be due to the sheer scale of mass transport, but it also arises from a system of active and non-active zones located throughout contemporary terminals. This photo series emphasises the "emptiness" of these overlooked left-over spaces that result from demands of circulation and construction.1. We Move the WorldTo many travellers, airport gate lounges and their surrounding facilities are loaded with a variety of contradictory associations and affects. Their open warehouse banality and hard industrial sterility tune our bodies to the vast technical and commercial systems that are imbricated through almost every aspect of contemporary everyday life.Here at the departure gate the traveller's body comes to a moment's rest. They are granted a short respite from the anxious routines of check in, body scans, security, information processing, passport scanning, itineraries, boarding procedures and wayfaring the terminal. The landside processing system deposits them at this penultimate point before final propulsion into the invisible airways that pipe them into their destination. We hear the broadcasting of boarding times, check-in times, name's of people that break them away from stillness, forcing people to move, to re-arrange themselves, or to hurry up. Along the way the passenger encounters a variety of techno-spatial experiences that sit at odds with the overriding discourse of velocity, speed and efficiency that lie at the centre of our social understanding of air travel. The airline's phantasmagorical projections of itself as guarantor and enabler of mass mobilities coincides uncomfortably with the passenger's own wish-fulfilment of escape and freedom.In this we can agree with the designer Bruce Mau when he suggests that these projection systems, comprised of "openings of every sort — in schedules, in urban space, on clothes, in events, on objects, in sightlines — are all inscribed with the logic of the market” (Mau 7). The advertising slogans and images everywhere communicate the dual concept that the aviation industry can deliver the world to us on time while simultaneously porting us to any part of the world still willing to accept Diners, VISA or American Express. At each point along the way these openings exhort us to stop, to wait in line, to sit still or to be patient. The weird geographies depicted by the light boxes appear like interpenetrating holes in space and time. These travel portals are strangely still, and only activated by the impending promise of movement.Be still and relax. Your destination is on its way. 2. Attentive AttentionAlongside the panoramic widescreen windows that frame the choreography of the tarmac and flight paths outside, appear luminous advertising light boxes. Snapped tightly to grid and locked into strategic sightlines and thoroughfares, these wall pieces are filled with a rotating menu of contemporary airport haiku and ersatz Swiss graphic design.Mechanically conditioned air pumped out of massive tubes creates the atmosphere for a very particular amalgam of daylight, tungsten, and fluorescent light waves. Low-oxygen-emitting indoor plants are no match for the diesel-powered plant rooms that maintain the constant flow of air to every nook and cranny of this massive processing machine. As Rem Koolhaas puts it, "air conditioning has launched the endless building. If architecture separates buildings, air conditioning unites them" (Koolhaas). In Koolhaas's lingo, these are complex "junkspaces" unifying, colliding and coalescing a number of different circulatory systems, temporalities and mobilities.Gillian Fuller reminds us there is a lot of stopping and going and stopping in the global circulatory system typified by air-terminal-space.From the packing of clothes in fixed containers to strapping your belt – tight and low – stillness and all its requisite activities, technologies and behaviours are fundamental to the ‘flow’ architectures that organize the motion of the globalizing multitudes of today (Fuller, "Store" 63). It is precisely this functional stillness organised around the protocols of store and forward that typifies digital systems, the packet switching of network cultures and the junkspace of airports alike.In these zones of transparency where everything is on view, the illuminated windows so proudly brought to us by J C Decaux flash forward to some idealized moment in the future. In this anticipatory moment, the passenger's every fantasy of in-flight service is attended to. The ultimate in attentiveness (think dimmed lights, soft pillows and comfy blankets), this still image is captured from an improbable future suspended behind the plywood and steel seating available in the moment —more reminiscent of park benches in public parks than the silver-service imagined for the discerning traveller.3. We Know ChicagoSelf-motion is itself a demonstration against the earth-binding weight of gravity. If we climb or fly, our defiance is greater (Appleyard 180).The commercial universe of phones, cameras, computer network software, financial instruments, and an array of fancy new gadgets floating in the middle of semi-forgotten transit spaces constitutes a singular interconnected commercial organism. The immense singularity of these claims to knowledge and power loom solemnly before us asserting their rights in the Esperanto of "exclusive rollover minutes", "nationwide long distance", "no roaming charges" and insider local knowledge. The connective tissue that joins one part of the terminal to a commercial centre in downtown Chicago is peeled away, revealing techno-veins and tendrils reaching to the sky. It's a graphic view that offers none of the spectacular openness and flights of fancy associated with the transit lounges located on the departure piers and satellites. Along these circulatory ribbons we experience the still photography and the designer's arrangement of type to attract the eye and lure the body. The blobby diagonals of the telco's logo blend seamlessly with the skyscraper's ribbons of steel, structural exoskeleton and wireless telecommunication cloud.In this plastinated anatomy, the various layers of commercially available techno-space stretch out before the traveller. Here we have no access to the two-way vistas made possible by the gigantic transparent tube structures of the contemporary air terminal. Waiting within the less travelled zones of the circulatory system we find ourselves suspended within the animating system itself. In these arteries and capillaries the flow is spread out and comes close to a halt in the figure of the graphic logo. We know Chicago is connected to us.In the digital logic of packet switching and network effects, there is no reason to privilege the go over the stop, the moving over the waiting. These light box portals do not mirror our bodies, almost at a complete standstill now. Instead they echo the commercial product world that they seek to transfuse us into. What emerges is a new kind of relational aesthetics that speaks to the complex corporeal, temporal, and architectural dimensions of stillness and movement in transit zones: like "a game, whose forms, patterns and functions develop and evolve according to periods and social contexts” (Bourriaud 11). 4. Machine in the CaféIs there a possible line of investigation suggested by the fact that sound waves become visible on the fuselage of jet planes just before they break the sound barrier? Does this suggest that the various human senses are translatable one into the other at various intensities (McLuhan 180)?Here, the technological imaginary contrasts itself with the techno alfresco dining area enclosed safely behind plate glass. Inside the cafes and bars, the best businesses in the world roll out their biggest guns to demonstrate the power, speed and scale of their network coverage (Remmele). The glass windows and light boxes "have the power to arrest a crowd around a commodity, corralling them in chic bars overlooking the runway as they wait for their call, but also guiding them where to go next" (Fuller, "Welcome" 164). The big bulbous plane sits plump in its hangar — no sound barriers broken here. It reassures us that our vehicle is somewhere there in the network, resting at its STOP before its GO. Peeking through the glass wall and sharing a meal with us, this interpenetrative transparency simultaneously joins and separates two planar dimensions — machinic perfection on one hand, organic growth and death on the other (Rowe and Slutsky; Fuller, "Welcome").Bruce Mau is typical in suggesting that the commanding problem of the twentieth century was speed, represented by the infamous image of a US Navy Hornet fighter breaking the sound barrier in a puff of smoke and cloud. It has worked its way into every aspect of the design experience, manufacturing, computation and transport.But speed masks more than it reveals. The most pressing problem facing designers and citizens alike is growth — from the unsustainable logic of infinite growth in GDP to the relentless application of Moore's Law to the digital networks and devices that define contemporary society in the first world. The shift of emphasis from speed to growth as a time-based event with breaking points and moments of rupture has generated new possibilities. "Growth is nonlinear and unpredictable ... Few of us are ready to admit that growth is constantly shadowed by its constitutive opposite, that is equal partners with death” (Mau 497).If speed in part represents a flight from death (Virilio), growth invokes its biological necessity. In his classic study of the persistence of the pastoral imagination in technological America, The Machine in the Garden, Leo Marx charted the urge to idealize rural environments at the advent of an urban industrialised America. The very idea of "the flight from the city" can be understood as a response to the onslaught of technological society and it's deathly shadow. Against the murderous capacity of technological society stood the pastoral ideal, "incorporated in a powerful metaphor of contradiction — a way of ordering meaning and value that clarifies our situation today" (Marx 4). 5. Windows at 35,000 FeetIf waiting and stillness are active forms of bodily engagement, we need to consider the different layers of motion and anticipation embedded in the apprehension of these luminous black-box windows. In The Virtual Window, Anne Friedberg notes that the Old Norse derivation of the word window “emphasizes the etymological root of the eye, open to the wind. The window aperture provides ventilation for the eye” (103).The virtual windows we are considering here evoke notions of view and shelter, open air and sealed protection, both separation from and connection to the outside. These windows to nowhere allow two distinct visual/spatial dimensions to interface, immediately making the visual field more complex and fragmented. Always simultaneously operating on at least two distinct fields, windows-within-windows provide a specialized mode of spatial and temporal navigation. As Gyorgy Kepes suggested in the 1940s, the transparency of windows "implies more than an optical characteristic; it implies a broader spatial order. Transparency means a simultaneous perception of different spatial locations" (Kepes 77).The first windows in the world were openings in walls, without glass and designed to allow air and light to fill the architectural structure. Shutters were fitted to control air flow, moderate light and to enclose the space completely. It was not until the emergence of glass technologies (especially in Holland, home of plate glass for the display of commercial products) that shielding and protection also allowed for unhindered views (by way of transparent glass). This gives rise to the thesis that windows are part of a longstanding architectural/technological system that moderates the dual functions of transparency and separation. With windows, multi-dimensional planes and temporalities can exist in the same time and space — hence a singular point of experience is layered with many other dimensions. Transparency and luminosity "ceases to be that which is perfectly clear and becomes instead that which is clearly ambiguous" (Rowe and Slutsky 45). The light box air-portals necessitate a constant fluctuation and remediation that is at once multi-planar, transparent and "hard to read". They are informatic.From holes in the wall to power lunch at 35,000 feet, windows shape the manner in which light, information, sights, smells, temperature and so on are modulated in society. "By allowing the outside in and the inside out, [they] enable cosmos and construction to innocently, transparently, converge" (Fuller, "Welcome" 163). Laptop, phone, PDA and light box point to the differential mobilities within a matrix that traverses multiple modes of transparency and separation, rest and flight, stillness and speed.6. Can You Feel It?Increasingly the whole world has come to smell alike: gasoline, detergents, plumbing, and junk foods coalesce into the catholic smog of our age (Illich 47).In these forlorn corners of mobile consumption, the dynamic of circulation simultaneously slows and opens out. The surfaces of inscription implore us to see them at precisely the moment we feel unseen, unguided and off-camera. Can you see it, can you feel it, can you imagine the unimaginable, all available to us on demand? Expectation and anticipation give us something to look forward to, but we're not sure we want what's on offer.Air travel radicalizes the separation of the air traveller from ground at one instance and from the atmosphere at another. Air, light, temperature and smell are all screened out or technologically created by the terminal plant and infrastructure. The closer the traveller moves towards stillness, the greater the engagement with senses that may have been ignored by the primacy of the visual in so much of this circulatory space. Smell, hunger, tiredness, cold and hardness cannot be screened out.In this sense, the airplanes we board are terminal extensions, flying air-conditioned towers or groundscrapers jet-propelled into highways of the air. Floating above the horizon, immersed in a set of logistically ordained trajectories and pressurized bubbles, we look out the window and don't see much at all. Whatever we do see, it's probably on the screen in front of us which disconnects us from one space-time-velocity at the same time that it plugs us into another set of relations. As Koolhaas says, junkspace is "held together not by structure, but by skin, like a bubble" (Koolhaas). In these distended bubbles, the traveler momentarily occupies an uncommon transit space where stillness is privileged and velocity is minimized. The traveler's body itself is "engaged in and enacting a whole kaleidoscope of different everyday practices and forms" during the course of this less-harried navigation (Bissell 282).7. Elevator MusicsThe imaginary wheel of the kaleidoscope spins to reveal a waiting body-double occupying the projected territory of what appears to be a fashionable Miami. She's just beyond our reach, but beside her lies a portal to another dimension of the terminal's vascular system.Elevators and the networks of shafts and vents that house them, are to our buildings like veins and arteries to the body — conduits that permeate and structure the spaces of our lives while still remaining separate from the fixity of the happenings around them (Garfinkel 175). The terminal space contains a number of apparent cul-de-sacs and escape routes. Though there's no background music piped in here, another soundtrack can be heard. The Muzak corporation may douse the interior of the elevator with its own proprietary aural cologne, but at this juncture the soundscape is more "open". This functional shifting of sound from figure to ground encourages peripheral hearing, providing "an illusion of distended time", sonically separated from the continuous hum of "generators, ventilation systems and low-frequency electrical lighting" (Lanza 43).There is another dimension to this acoustic realm: “The mobile ecouteur contracts the flows of information that are supposed to keep bodies usefully and efficiently moving around ... and that turn them into functions of information flows — the speedy courier, the networking executive on a mobile phone, the scanning eyes of the consumer” (Munster 18).An elevator is a grave says an old inspector's maxim, and according to others, a mechanism to cross from one world to another. Even the quintessential near death experience with its movement down a long illuminated tunnel, Garfinkel reminds us, “is not unlike the sensation of movement we experience, or imagine, in a long swift elevator ride” (Garfinkel 191).8. States of SuspensionThe suspended figure on the screen occupies an impossible pose in an impossible space: half falling, half resting, an anti-angel for today's weary air traveller. But it's the same impossible space revealed by the airport and bundled up in the experience of flight. After all, the dimension this figures exists in — witness the amount of activity in his suspension — is almost like a black hole with the surrounding universe collapsing into it. The figure is crammed into the light box uncomfortably like passengers in the plane, and yet occupies a position that does not exist in the Cartesian universe.We return to the glossy language of advertising, its promise of the external world of places and products delivered to us by the image and the network of travel. (Remmele) Here we can go beyond Virilio's vanishing point, that radical reversibility where inside and outside coincide. Since everybody has already reached their destination, for Virilio it has become completely pointless to leave: "the inertia that undermines your corporeity also undermines the GLOBAL and the LOCAL; but also, just as much, the MOBILE and the IMMOBILE” (Virilio 123; emphasis in original).In this clinical corner of stainless steel, glass bricks and exit signs hangs an animated suspension that articulates the convergence of a multitude of differentials in one image. Fallen into the weirdest geometry in the world, it's as if the passenger exists in a non-place free of all traces. Flows and conglomerates follow one another, accumulating in the edges, awaiting their moment to be sent off on another trajectory, occupying so many spatio-temporal registers in a dynamic range of mobility.ReferencesAppleyard, Donald.

In the last three years a new filthy vocabulary of social class has emerged in Britain. The word “chav”, and its various synonyms and regional variations, has become a ubiquitous term of abuse for white working class subjects. An entire slang vocabulary has emerged around chav. Acronyms, such as “Council Housed and Vile” have sprung up to explain the term. Folk etymologies and some scholarly sources suggest that the term chav might derive from a distortion of a Romany word for a child, while others suggests it is a derivative of the term charver, long used in the North East of England to describe the disenfranchised white poor (see Nayak). In current parlance, the term chav is aligned “with stereotypical notions of lower-class” and is above all “a term of intense class-based abhorrence” (Haywood and Yar 16). Routinely demonized within news media, television comedy programmes, and internet sites (such as the chavscum) the level of disgust mobilized by the figure of the chav is suggestive of a heightened class antagonism that marks a new episode of class struggle in Britain. Social class is often represented through highly caricatured figures—the toff, the chav—figures that are referred to in highly emotive terms. One of the ways in which social class is emotionally mediated is through repeated expressions of disgust at the habits and behaviour of those deemed to belong to a lower social class. An everyday definition of disgust would be: an emotion experienced and expressed as a sickening feeling of revulsion, loathing, or nausea. The physicality of disgust reactions means that the communication of disgust draws heavily on metaphors of sensation. As William Miller notes, disgust “needs images of bad taste, foul smells, creepy touchings, ugly sights, bodily secretions and excretions to articulate the judgments it asserts” (218). Our disgust reactions are often revealing of wider social power relations. As Sara Ahmed notes: When thinking about how bodies become objects of disgust, we can see that disgust is crucial to power relations. … Disgust at “that which is below” functions to maintain the power relations between above and below, through which “aboveness” and “belowness” become properties of particular bodies, objects and spaces (89). Ahmed’s account of the connection between disgust and power relations echoes Beverly Skeggs’ influential account of “class making”. As Skeggs suggests, class as a concept, and as a process of classification and social positioning, is not pre-given but is always in production and is continually re-figured (3). Social class virtually disappeared as a central site of analysis within cultural and media studies in the late 1980s, a disappearance that was mirrored by a similar retreat from the taxonomy of class within wider social and political discourse (Skeggs 45). This is not to say that class distinctions, however we measure them, have been eroded or are in decline. On the contrary, class disappeared as a central site of analysis at precisely the same time that “economic polarization” reached “unparalleled depths” in Britain (ibid.). As the term “working class” has been incrementally emptied of meaning, teaching and researching issues of class inequality is now often seen as “paranoid” and felt to be embarrassing and shameful (see Sayer). (Roland Barthes uses the concept of ‘ex-nomination’ to explain how (and why) social class is emptied of meaning in this way. According to Barthes, this process is one of the central mechanisms through which dominant classes naturalise their values.) In the last two decades academics from working class backgrounds and, perhaps most perversely, those who work within disciplines that were founded upon research on class, have increasingly experienced their own class origins as a “filthy secret”. If social class “directly articulated” and as “the object of analysis, has largely disappeared” (Skeggs 46) within the academy and within wider social and political discourses, portrayals of class differences have nevertheless persisted within popular media. In particular, the emergence of the grotesque and comic figure of the chav within a range of contemporary British media, primarily television comedy, reality-genre television, Internet forums and newspapers, has made class differences and antagonisms explicitly visible in contemporary Britain. Class-based discrimination and open snobbery is made socially acceptable through claims that this vicious name-calling has a ‘satirical’ function. Laughing at something is “an act of expulsion” that closely resembles the rejecting movement of disgust reactions (Menninghaus 11). In the case of laughter at those of a lower class, laughter is boundary-forming; it creates a distance between “them” and “us”, and asserts moral judgments and a higher class position. Laughter at chavs is a way of managing and authorizing class disgust, contempt, and anxiety. Popular media can be effective means of communicating class disgust and in so doing, work to produce ‘class communities’ in material, political and affective senses. In the online vocabulary of chav hate, we can further discern the ways in which class disgust is performed in ways that are community-forming. The web site, urbandictionary.com is an online slang dictionary that functions as an unofficial online authority on English language slang. Urbandictionary.com is modelled on an internet forum in which (unregistered) users post definitions of new or existing slang terms, which are then reviewed by volunteer editors. Users vote on definitions by clicking a thumb up or thumb down icon and posts are then ranked according to the votes they have accrued. Urbandictionary currently hosts 300,000 definitions of slang terms and is ranked as one of the 2000 highest web traffic sites in the world. There were 368 definitions of the term chav posted on the site at the time of writing and I have extracted below a small number of indicative phrases taken from some of the most highly ranked posts. all chavs are filth chavs …. the cancer of the United Kingdom filthy, disgusting, dirty, loud, ugly, stupid arseholes that threaten, fight, cause trouble, impregnate 14 year olds, ask for money, ask for fags, ….steal your phones, wear crap sports wear, drink cheap cider and generally spread their hate. A social underclass par excellence. The absolute dregs of modern civilization The only good chav is dead one. The only thing better than that is a mass grave full of dead chavs and a 24 hour work crew making way for more… This disgust speech generates a set of effects, which adhere to and produce the filthy figure and qualities of chav. The dictionary format is significant here because, like the accompanying veneer of irony, it grants a strange authority to the dehumanising bigotry of the posts. Urbandictionary illustrates how class disgust is actively made through repetition. Through the repetition of disgust reactions, the negative properties attributed to chav make this figure materialize as representative of a group who embodies those disgusting qualities – a group who are “lower than human or civil life” (Ahmed 97). As users add to and build the definition of “the chav” within the urban dictionary site, they interact with one another and a conversational environment emerges. The voting system works on this site as a form of peer authorization that encourages users to invoke more and more intense and affective disgust reactions. As Ngai suggests, disgust involves an expectation of concurrence, and disgust reactions seek “to include or draw others into its exclusion of its object, enabling a strange kind of sociability” (336). This sociability has a particular specificity within online communities in which anonymity gives community members license to express their disgust in extreme and virulent ways. The interactivity of these internet forums, and the real and illusory immediacy they transmit, makes online forums intensely affective communal spaces/places within which disgust reactions can be rapidly shared and accrued. As the web becomes more “writable”, through the development and dissemination of shared annotation software, web users are moving from consuming content to creating it ‘in the form of discussion boards, weblogs, wikis, and other collaborative and conversational media” (Golder 2). Within new media spaces such as urbandictionary, we are not only viewers but active users who can go into, enter and affect representational spaces and places. In the case of chavs, users can not only read about them, but have the power to produce the chav as a knowable figure. The chav thread on urbandictionary and similar chav hate forums work to constitute materially the exaggerated excessive corporeality of the chav figure. These are spaces/places in which class disgust is actively generated – class live. With each new post, there is an accruement of disgust. Each post breathes life into the squalid and thrillingly affective imaginary body of the filthy chav. Class disgust is intimately tied to issues of racial difference. These figures constitute an unclean “sullied urban “underclass”“, “forever placed at the borders of whiteness as the socially excluded, the economically redundant” (Nayak 82, 102-3). Whilst the term chav is a term of abuse directed almost exclusively towards the white poor, chavs are not invisible normative whites, but rather hypervisible “filthy whites”. In a way that bears striking similarities to US white trash figure, and the Australian figure of the Bogan, the chav figure foregrounds a dirty whiteness – a whiteness contaminated with poverty. This borderline whiteness is evidenced through claims that chavs appropriate black American popular culture through their clothing, music, and forms of speech, and have geographical, familial and sexual intimacy with working class blacks and Asians. This intimacy is represented by the areas in which chavs live and their illegitimate mixed race children as well as, more complexly, by their filthy white racism. Metaphors of disease, invasion and excessive breeding that are often invoked within white racist responses to immigrants and ethnic minorities are mobilized by the white middle-class in order to differentiate their “respectable whiteness” from the whiteness of the lower class chavs (see Nayak 84). The process of making white lower class identity filthy is an attempt to differentiate between respectable and non-respectable forms of whiteness (and an attempt to abject the white poor from spheres of white privilege). Disgust reactions work not only to give meaning to the figure of the chav but, more complicatedly, constitute a category of being – chav being. So whilst the figures of the chav and chavette have a virtual existence within newspapers, Internet forums and television shows, the chav nevertheless takes symbolic shape in ways that have felt material and physical effects upon those interpellated as “chav”. We can think here of the way in which” signs of chavness”, such as the wearing of certain items or brands of clothing have been increasingly used to police access to public spaces, such as nightclubs and shopping centres since 2003. The figure of the chav becomes a body imbued with negative affect. This affect travels, it circulates and leaks out into public space and shapes everyday perceptual practices. The social policing of chavs foregrounds the disturbing ease with which imagined “emotional qualities slide into corporeal qualities” (Ngai 573). Chav disgust is felt and lived. Experiencing the frisson of acting like a chav has become a major leisure occupation in Britain where middle class students now regularly hold “chav nites”, in which they dress up as chavs and chavettes. These students dress as chavs, carry plastic bags from the cut-price food superstores, drink cider and listen to ‘chav music’, in order to enjoy the affect of being an imaginary chav. In April 2006 the front page of The Sun featured Prince William dressed up as a chav with the headline, “Future Bling of England”, The story details how the future king: “joined in the fun as his platoon donned chav-themed fancy dress to mark the completion of their first term” at Sandhurst military academy. William, we were told, “went to a lot of trouble thinking up what to wear” (white baseball cap, sweatshirt, two gold chains), and was challenged to “put on a chavvy accent and stop speaking like a royal”. These examples of ironic class–passing represent a new era of ‘slumming it’ that recalls the 19th century Victorian slummers, who descended on the East End of London in their many thousands, in pursuit of abject encounters – touristic tastes of the illicit pleasures associated with the immoral, urban poor. This new chav ‘slumming it’ makes no pretence at any moral imperative, it doesn’t pretend to be sociological, there is no “field work”, no ethnography, no gathering of knowledge about the poor, no charity, no reaching out to touch, and no liberal guilt, there is nothing but ‘filthy pleasure’. The cumulative effect of disgust at chavs is the blocking of the disenfranchised white poor from view; they are rendered invisible and incomprehensible. Nevertheless, chav has become an increasingly complex identity category and some of those interpellated as filthy chavs have now reclaimed the term as an affirmative sub-cultural identity. This trans-coding of chav is visible within popular music acts, such as white teenage rapper Lady Sovereign and the acclaimed pop icon and urban poet Mike Skinner (who releases records as The Streets). Journalist Julie Burchill has repeatedly attempted both to defend, and claim for herself, a chav identity and in 2005, the tabloid newspaper The Sun, a propagator of chav hate, ran a ‘Proud to be Chav’ campaign. Nevertheless, this ‘chav pride’ is deceptive, for like the US term ‘white trash’ – now widely adopted within celebrity culture – this ‘pride’ works as an enabling identity category only for those who have acquired enough cultural capital and social mobility to ‘rise above the filth’. Since the publication in English of Julia Kristeva’s Power’s of Horror: An Essay on Abjection in 1982, an entire theoretical paradigm has emerged that celebrates the ‘transgressive’ potential of encounters with filth. Such theoretical ‘abject encounters’ are rarely subversive but are on the contrary an increasingly normative and problematic feature of a media and cultural studies devoid of political direction. Instead of assuming that confrontations with ‘filth’ are ‘necessarily subversive and disruptive’ we need to rethink abjection as a violent exclusionary social force. As Miller notes, ‘disgust does not so much solve the dilemma of social powerlessness as diagnose it powerfully’ (353). Theoretical accounts of media and culture that invoke ‘the transformative potential of filth’ too often marginalize the real dirty politics of inequality. References Ahmed, Sara.

By the time you read this, it will be wrong. Things seemed to be moving so fast in these first days after airplanes crashed into the World Trade Center, the Pentagon, and the Pennsylvania earth. Each certainty is as carelessly dropped as it was once carelessly assumed. The sounds of lower Manhattan that used to serve as white noise for residents—sirens, screeches, screams—are no longer signs without a referent. Instead, they make folks stare and stop, hurry and hustle, wondering whether the noises we know so well are in fact, this time, coefficients of a new reality. At the time of writing, the events themselves are also signs without referents—there has been no direct claim of responsibility, and little proof offered by accusers since the 11th. But it has been assumed that there is a link to US foreign policy, its military and economic presence in the Arab world, and opposition to it that seeks revenge. In the intervening weeks the US media and the war planners have supplied their own narrow frameworks, making New York’s “ground zero” into the starting point for a new escalation of global violence. We want to write here about the combination of sources and sensations that came that day, and the jumble of knowledges and emotions that filled our minds. Working late the night before, Toby was awoken in the morning by one of the planes right overhead. That happens sometimes. I have long expected a crash when I’ve heard the roar of jet engines so close—but I didn’t this time. Often when that sound hits me, I get up and go for a run down by the water, just near Wall Street. Something kept me back that day. Instead, I headed for my laptop. Because I cannot rely on local media to tell me very much about the role of the US in world affairs, I was reading the British newspaper The Guardian on-line when it flashed a two-line report about the planes. I looked up at the calendar above my desk to see whether it was April 1st. Truly. Then I got off-line and turned on the TV to watch CNN. That second, the phone rang. My quasi-ex-girlfriend I’m still in love with called from the mid-West. She was due to leave that day for the Bay Area. Was I alright? We spoke for a bit. She said my cell phone was out, and indeed it was for the remainder of the day. As I hung up from her, my friend Ana rang, tearful and concerned. Her husband, Patrick, had left an hour before for work in New Jersey, and it seemed like a dangerous separation. All separations were potentially fatal that day. You wanted to know where everyone was, every minute. She told me she had been trying to contact Palestinian friends who worked and attended school near the event—their ethnic, religious, and national backgrounds made for real poignancy, as we both thought of the prejudice they would (probably) face, regardless of the eventual who/what/when/where/how of these events. We agreed to meet at Bruno’s, a bakery on La Guardia Place. For some reason I really took my time, though, before getting to Ana. I shampooed and shaved under the shower. This was a horror, and I needed to look my best, even as men and women were losing and risking their lives. I can only interpret what I did as an attempt to impose normalcy and control on the situation, on my environment. When I finally made it down there, she’d located our friends. They were safe. We stood in the street and watched the Towers. Horrified by the sight of human beings tumbling to their deaths, we turned to buy a tea/coffee—again some ludicrous normalization—but were drawn back by chilling screams from the street. Racing outside, we saw the second Tower collapse, and clutched at each other. People were streaming towards us from further downtown. We decided to be with our Palestinian friends in their apartment. When we arrived, we learnt that Mark had been four minutes away from the WTC when the first plane hit. I tried to call my daughter in London and my father in Canberra, but to no avail. I rang the mid-West, and asked my maybe-former novia to call England and Australia to report in on me. Our friend Jenine got through to relatives on the West Bank. Israeli tanks had commenced a bombardment there, right after the planes had struck New York. Family members spoke to her from under the kitchen table, where they were taking refuge from the shelling of their house. Then we gave ourselves over to television, like so many others around the world, even though these events were happening only a mile away. We wanted to hear official word, but there was just a huge absence—Bush was busy learning to read in Florida, then leading from the front in Louisiana and Nebraska. As the day wore on, we split up and regrouped, meeting folks. One guy was in the subway when smoke filled the car. Noone could breathe properly, people were screaming, and his only thought was for his dog DeNiro back in Brooklyn. From the panic of the train, he managed to call his mom on a cell to ask her to feed “DeNiro” that night, because it looked like he wouldn’t get home. A pregnant woman feared for her unborn as she fled the blasts, pushing the stroller with her baby in it as she did so. Away from these heart-rending tales from strangers, there was the fear: good grief, what horrible price would the US Government extract for this, and who would be the overt and covert agents and targets of that suffering? What blood-lust would this generate? What would be the pattern of retaliation and counter-retaliation? What would become of civil rights and cultural inclusiveness? So a jumble of emotions came forward, I assume in all of us. Anger was not there for me, just intense sorrow, shock, and fear, and the desire for intimacy. Network television appeared to offer me that, but in an ultimately unsatisfactory way. For I think I saw the end-result of reality TV that day. I have since decided to call this ‘emotionalization’—network TV’s tendency to substitute analysis of US politics and economics with a stress on feelings. Of course, powerful emotions have been engaged by this horror, and there is value in addressing that fact and letting out the pain. I certainly needed to do so. But on that day and subsequent ones, I looked to the networks, traditional sources of current-affairs knowledge, for just that—informed, multi-perspectival journalism that would allow me to make sense of my feelings, and come to a just and reasoned decision about how the US should respond. I waited in vain. No such commentary came forward. Just a lot of asinine inquiries from reporters that were identical to those they pose to basketballers after a game: Question—‘How do you feel now?’ Answer—‘God was with me today.’ For the networks were insistent on asking everyone in sight how they felt about the end of las torres gemelas. In this case, we heard the feelings of survivors, firefighters, viewers, media mavens, Republican and Democrat hacks, and vacuous Beltway state-of-the-nation pundits. But learning of the military-political economy, global inequality, and ideologies and organizations that made for our grief and loss—for that, there was no space. TV had forgotten how to do it. My principal feeling soon became one of frustration. So I headed back to where I began the day—The Guardian web site, where I was given insightful analysis of the messy factors of history, religion, economics, and politics that had created this situation. As I dealt with the tragedy of folks whose lives had been so cruelly lost, I pondered what it would take for this to stop. Or whether this was just the beginning. I knew one thing—the answers wouldn’t come from mainstream US television, no matter how full of feelings it was. And that made Toby anxious. And afraid. He still is. And so the dreams come. In one, I am suddenly furloughed from my job with an orchestra, as audience numbers tumble. I make my evening-wear way to my locker along with the other players, emptying it of bubble gum and instrument. The next night, I see a gigantic, fifty-feet high wave heading for the city beach where I’ve come to swim. Somehow I am sheltered behind a huge wall, as all the people around me die. Dripping, I turn to find myself in a media-stereotype “crack house” of the early ’90s—desperate-looking black men, endless doorways, sudden police arrival, and my earnest search for a passport that will explain away my presence. I awake in horror, to the realization that the passport was already open and stamped—racialization at work for Toby, every day and in every way, as a white man in New York City. Ana’s husband, Patrick, was at work ten miles from Manhattan when “it” happened. In the hallway, I overheard some talk about two planes crashing, but went to teach anyway in my usual morning stupor. This was just the usual chatter of disaster junkies. I didn’t hear the words, “World Trade Center” until ten thirty, at the end of the class at the college I teach at in New Jersey, across the Hudson river. A friend and colleague walked in and told me the news of the attack, to which I replied “You must be fucking joking.” He was a little offended. Students were milling haphazardly on the campus in the late summer weather, some looking panicked like me. My first thought was of some general failure of the air-traffic control system. There must be planes falling out of the sky all over the country. Then the height of the towers: how far towards our apartment in Greenwich Village would the towers fall? Neither of us worked in the financial district a mile downtown, but was Ana safe? Where on the college campus could I see what was happening? I recognized the same physical sensation I had felt the morning after Hurricane Andrew in Miami seeing at a distance the wreckage of our shattered apartment across a suburban golf course strewn with debris and flattened power lines. Now I was trapped in the suburbs again at an unbridgeable distance from my wife and friends who were witnessing the attacks first hand. Were they safe? What on earth was going on? This feeling of being cut off, my path to the familiar places of home blocked, remained for weeks my dominant experience of the disaster. In my office, phone calls to the city didn’t work. There were six voice-mail messages from my teenaged brother Alex in small-town England giving a running commentary on the attack and its aftermath that he was witnessing live on television while I dutifully taught my writing class. “Hello, Patrick, where are you? Oh my god, another plane just hit the towers. Where are you?” The web was choked: no access to newspapers online. Email worked, but no one was wasting time writing. My office window looked out over a soccer field to the still woodlands of western New Jersey: behind me to the east the disaster must be unfolding. Finally I found a website with a live stream from ABC television, which I watched flickering and stilted on the tiny screen. It had all already happened: both towers already collapsed, the Pentagon attacked, another plane shot down over Pennsylvania, unconfirmed reports said, there were other hijacked aircraft still out there unaccounted for. Manhattan was sealed off. George Washington Bridge, Lincoln and Holland tunnels, all the bridges and tunnels from New Jersey I used to mock shut down. Police actions sealed off the highways into “the city.” The city I liked to think of as the capital of the world was cut off completely from the outside, suddenly vulnerable and under siege. There was no way to get home. The phone rang abruptly and Alex, three thousand miles away, told me he had spoken to Ana earlier and she was safe. After a dozen tries, I managed to get through and spoke to her, learning that she and Toby had seen people jumping and then the second tower fall. Other friends had been even closer. Everyone was safe, we thought. I sat for another couple of hours in my office uselessly. The news was incoherent, stories contradictory, loops of the planes hitting the towers only just ready for recycling. The attacks were already being transformed into “the World Trade Center Disaster,” not yet the ahistorical singularity of the emergency “nine one one.” Stranded, I had to spend the night in New Jersey at my boss’s house, reminded again of the boundless generosity of Americans to relative strangers. In an effort to protect his young son from the as yet unfiltered images saturating cable and Internet, my friend’s TV set was turned off and we did our best to reassure. We listened surreptitiously to news bulletins on AM radio, hoping that the roads would open. Walking the dog with my friend’s wife and son we crossed a park on the ridge on which Upper Montclair sits. Ten miles away a huge column of smoke was rising from lower Manhattan, where the stunning absence of the towers was clearly visible. The summer evening was unnervingly still. We kicked a soccer ball around on the front lawn and a woman walked distracted by, shocked and pale up the tree-lined suburban street, suffering her own wordless trauma. I remembered that though most of my students were ordinary working people, Montclair is a well-off dormitory for the financial sector and high rises of Wall Street and Midtown. For the time being, this was a white-collar disaster. I slept a short night in my friend’s house, waking to hope I had dreamed it all, and took the commuter train in with shell-shocked bankers and corporate types. All men, all looking nervously across the river toward glimpses of the Manhattan skyline as the train neared Hoboken. “I can’t believe they’re making us go in,” one guy had repeated on the station platform. He had watched the attacks from his office in Midtown, “The whole thing.” Inside the train we all sat in silence. Up from the PATH train station on 9th street I came onto a carless 6th Avenue. At 14th street barricades now sealed off downtown from the rest of the world. I walked down the middle of the avenue to a newspaper stand; the Indian proprietor shrugged “No deliveries below 14th.” I had not realized that the closer to the disaster you came, the less information would be available. Except, I assumed, for the evidence of my senses. But at 8 am the Village was eerily still, few people about, nothing in the sky, including the twin towers. I walked to Houston Street, which was full of trucks and police vehicles. Tractor trailers sat carrying concrete barriers. Below Houston, each street into Soho was barricaded and manned by huddles of cops. I had walked effortlessly up into the “lockdown,” but this was the “frozen zone.” There was no going further south towards the towers. I walked the few blocks home, found my wife sleeping, and climbed into bed, still in my clothes from the day before. “Your heart is racing,” she said. I realized that I hadn’t known if I would get back, and now I never wanted to leave again; it was still only eight thirty am. Lying there, I felt the terrible wonder of a distant bystander for the first-hand witness. Ana’s face couldn’t tell me what she had seen. I felt I needed to know more, to see and understand. Even though I knew the effort was useless: I could never bridge that gap that had trapped me ten miles away, my back turned to the unfolding disaster. The television was useless: we don’t have cable, and the mast on top of the North Tower, which Ana had watched fall, had relayed all the network channels. I knew I had to go down and see the wreckage. Later I would realize how lucky I had been not to suffer from “disaster envy.” Unbelievably, in retrospect, I commuted into work the second day after the attack, dogged by the same unnerving sensation that I would not get back—to the wounded, humbled former center of the world. My students were uneasy, all talked out. I was a novelty, a New Yorker living in the Village a mile from the towers, but I was forty-eight hours late. Out of place in both places. I felt torn up, but not angry. Back in the city at night, people were eating and drinking with a vengeance, the air filled with acrid sicklysweet smoke from the burning wreckage. Eyes stang and nose ran with a bitter acrid taste. Who knows what we’re breathing in, we joked nervously. A friend’s wife had fallen out with him for refusing to wear a protective mask in the house. He shrugged a wordlessly reassuring smile. What could any of us do? I walked with Ana down to the top of West Broadway from where the towers had commanded the skyline over SoHo; downtown dense smoke blocked the view to the disaster. A crowd of onlookers pushed up against the barricades all day, some weeping, others gawping. A tall guy was filming the grieving faces with a video camera, which was somehow the worst thing of all, the first sign of the disaster tourism that was already mushrooming downtown. Across the street an Asian artist sat painting the street scene in streaky black and white; he had scrubbed out two white columns where the towers would have been. “That’s the first thing I’ve seen that’s made me feel any better,” Ana said. We thanked him, but he shrugged blankly, still in shock I supposed. On the Friday, the clampdown. I watched the Mayor and Police Chief hold a press conference in which they angrily told the stream of volunteers to “ground zero” that they weren’t needed. “We can handle this ourselves. We thank you. But we don’t need your help,” Commissioner Kerik said. After the free-for-all of the first couple of days, with its amazing spontaneities and common gestures of goodwill, the clampdown was going into effect. I decided to go down to Canal Street and see if it was true that no one was welcome anymore. So many paths through the city were blocked now. “Lock down, frozen zone, war zone, the site, combat zone, ground zero, state troopers, secured perimeter, national guard, humvees, family center”: a disturbing new vocabulary that seemed to stamp the logic of Giuliani’s sanitized and over-policed Manhattan onto the wounded hulk of the city. The Mayor had been magnificent in the heat of the crisis; Churchillian, many were saying—and indeed, Giuliani quickly appeared on the cover of Cigar Afficionado, complete with wing collar and the misquotation from Kipling, “Captain Courageous.” Churchill had not believed in peacetime politics either, and he never got over losing his empire. Now the regime of command and control over New York’s citizens and its economy was being stabilized and reimposed. The sealed-off, disfigured, and newly militarized spaces of the New York through which I have always loved to wander at all hours seemed to have been put beyond reach for the duration. And, in the new post-“9/11” post-history, the duration could last forever. The violence of the attacks seemed to have elicited a heavy-handed official reaction that sought to contain and constrict the best qualities of New York. I felt more anger at the clampdown than I did at the demolition of the towers. I knew this was unreasonable, but I feared the reaction, the spread of the racial harassment and racial profiling that I had already heard of from my students in New Jersey. This militarizing of the urban landscape seemed to negate the sprawling, freewheeling, boundless largesse and tolerance on which New York had complacently claimed a monopoly. For many the towers stood for that as well, not just as the monumental outposts of global finance that had been attacked. Could the American flag mean something different? For a few days, perhaps—on the helmets of firemen and construction workers. But not for long. On the Saturday, I found an unmanned barricade way east along Canal Street and rode my bike past throngs of Chinatown residents, by the Federal jail block where prisoners from the first World Trade Center bombing were still being held. I headed south and west towards Tribeca; below the barricades in the frozen zone, you could roam freely, the cops and soldiers assuming you belonged there. I felt uneasy, doubting my own motives for being there, feeling the blood drain from my head in the same numbing shock I’d felt every time I headed downtown towards the site. I looped towards Greenwich Avenue, passing an abandoned bank full of emergency supplies and boxes of protective masks. Crushed cars still smeared with pulverized concrete and encrusted with paperwork strewn by the blast sat on the street near the disabled telephone exchange. On one side of the avenue stood a horde of onlookers, on the other television crews, all looking two blocks south towards a colossal pile of twisted and smoking steel, seven stories high. We were told to stay off the street by long-suffering national guardsmen and women with southern accents, kids. Nothing happening, just the aftermath. The TV crews were interviewing worn-out, dust-covered volunteers and firemen who sat quietly leaning against the railings of a park filled with scraps of paper. Out on the West Side highway, a high-tech truck was offering free cellular phone calls. The six lanes by the river were full of construction machinery and military vehicles. Ambulances rolled slowly uptown, bodies inside? I locked my bike redundantly to a lamppost and crossed under the hostile gaze of plainclothes police to another media encampment. On the path by the river, two camera crews were complaining bitterly in the heat. “After five days of this I’ve had enough.” They weren’t talking about the trauma, bodies, or the wreckage, but censorship. “Any blue light special gets to roll right down there, but they see your press pass and it’s get outta here. I’ve had enough.” I fronted out the surly cops and ducked under the tape onto the path, walking onto a Pier on which we’d spent many lazy afternoons watching the river at sunset. Dust everywhere, police boats docked and waiting, a crane ominously dredging mud into a barge. I walked back past the camera operators onto the highway and walked up to an interview in process. Perfectly composed, a fire chief and his crew from some small town in upstate New York were politely declining to give details about what they’d seen at “ground zero.” The men’s faces were dust streaked, their eyes slightly dazed with the shock of a horror previously unimaginable to most Americans. They were here to help the best they could, now they’d done as much as anyone could. “It’s time for us to go home.” The chief was eloquent, almost rehearsed in his precision. It was like a Magnum press photo. But he was refusing to cooperate with the media’s obsessive emotionalism. I walked down the highway, joining construction workers, volunteers, police, and firemen in their hundreds at Chambers Street. No one paid me any attention; it was absurd. I joined several other watchers on the stairs by Stuyvesant High School, which was now the headquarters for the recovery crews. Just two or three blocks away, the huge jagged teeth of the towers’ beautiful tracery lurched out onto the highway above huge mounds of debris. The TV images of the shattered scene made sense as I placed them into what was left of a familiar Sunday afternoon geography of bike rides and walks by the river, picnics in the park lying on the grass and gazing up at the infinite solidity of the towers. Demolished. It was breathtaking. If “they” could do that, they could do anything. Across the street at tables military policeman were checking credentials of the milling volunteers and issuing the pink and orange tags that gave access to ground zero. Without warning, there was a sudden stampede running full pelt up from the disaster site, men and women in fatigues, burly construction workers, firemen in bunker gear. I ran a few yards then stopped. Other people milled around idly, ignoring the panic, smoking and talking in low voices. It was a mainly white, blue-collar scene. All these men wearing flags and carrying crowbars and flashlights. In their company, the intolerance and rage I associated with flags and construction sites was nowhere to be seen. They were dealing with a torn and twisted otherness that dwarfed machismo or bigotry. I talked to a moustachioed, pony-tailed construction worker who’d hitched a ride from the mid-west to “come and help out.” He was staying at the Y, he said, it was kind of rough. “Have you been down there?” he asked, pointing towards the wreckage. “You’re British, you weren’t in World War Two were you?” I replied in the negative. “It’s worse ’n that. I went down last night and you can’t imagine it. You don’t want to see it if you don’t have to.” Did I know any welcoming ladies? he asked. The Y was kind of tough. When I saw TV images of President Bush speaking to the recovery crews and steelworkers at “ground zero” a couple of days later, shouting through a bullhorn to chants of “USA, USA” I knew nothing had changed. New York’s suffering was subject to a second hijacking by the brokers of national unity. New York had never been America, and now its terrible human loss and its great humanity were redesignated in the name of the nation, of the coming war. The signs without a referent were being forcibly appropriated, locked into an impoverished patriotic framework, interpreted for “us” by a compliant media and an opportunistic regime eager to reign in civil liberties, to unloose its war machine and tighten its grip on the Muslim world. That day, drawn to the river again, I had watched F18 fighter jets flying patterns over Manhattan as Bush’s helicopters came in across the river. Otherwise empty of air traffic, “our” skies were being torn up by the military jets: it was somehow the worst sight yet, worse than the wreckage or the bands of disaster tourists on Canal Street, a sign of further violence yet to come. There was a carrier out there beyond New York harbor, there to protect us: the bruising, blustering city once open to all comers. That felt worst of all. In the intervening weeks, we have seen other, more unstable ways of interpreting the signs of September 11 and its aftermath. Many have circulated on the Internet, past the blockages and blockades placed on urban spaces and intellectual life. Karl-Heinz Stockhausen’s work was banished (at least temporarily) from the canon of avant-garde electronic music when he described the attack on las torres gemelas as akin to a work of art. If Jacques Derrida had described it as an act of deconstruction (turning technological modernity literally in on itself), or Jean Baudrillard had announced that the event was so thick with mediation it had not truly taken place, something similar would have happened to them (and still may). This is because, as Don DeLillo so eloquently put it in implicit reaction to the plaintive cry “Why do they hate us?”: “it is the power of American culture to penetrate every wall, home, life and mind”—whether via military action or cultural iconography. All these positions are correct, however grisly and annoying they may be. What GK Chesterton called the “flints and tiles” of nineteenth-century European urban existence were rent asunder like so many victims of high-altitude US bombing raids. As a First-World disaster, it became knowable as the first-ever US “ground zero” such precisely through the high premium immediately set on the lives of Manhattan residents and the rarefied discussion of how to commemorate the high-altitude towers. When, a few weeks later, an American Airlines plane crashed on take-off from Queens, that borough was left open to all comers. Manhattan was locked down, flown over by “friendly” bombers. In stark contrast to the open if desperate faces on the street of 11 September, people went about their business with heads bowed even lower than is customary. Contradictory deconstructions and valuations of Manhattan lives mean that September 11 will live in infamy and hyper-knowability. The vengeful United States government and population continue on their way. Local residents must ponder insurance claims, real-estate values, children’s terrors, and their own roles in something beyond their ken. New York had been forced beyond being the center of the financial world. It had become a military target, a place that was receiving as well as dispatching the slings and arrows of global fortune.

IntroductionBallarat’s Theatre Royal was the first permanent theatre built in inland Australia. Upon opening in 1858, it was acclaimed as having “the handsomest theatrical exterior in the colony” (Star, “Editorial” 7 Dec. 1889) and later acknowledged as “the grandest playhouse in all Australia” (Spielvogel, Papers Vol. 1 160). Born of Gold Rush optimism, the Royal was loved by many, yet the over-arching story of its ill-fated existence has failed to surface, in any coherent fashion, in official history. This article takes some first steps toward retrieving lost knowledge from fragmented archival records, and piecing together the story of why this purpose-built theatre ceased operation within a twenty-year period. A short history of the venue will be provided, to develop context. It will be argued that while a combination of factors, most of which were symptomatic of unfortunate timing, destroyed the longevity of the Royal, the principal problem was one of stigmatisation. This was an era in which the societal pressure to visibly conform to conservative values was intense and competition in the pursuit of profits was fierce.The cultural silence that befell the story of the Royal, after its demise, is explicable in relation to history being written by the victors and a loss of spokespeople since that time. As theatre arts historiographer McConachie (131) highlights, “Theatres, like places for worship and spectator sports, hold memories of the past in addition to providing a practical and cognitive framework for performance events in the present.” When that place, “a bounded area denoted by human agency and memory” (131), is lost in time, so too may be the socio-cultural lessons from the period, if not actively recalled and reconsidered. The purpose of this article is to present the beginning of an investigation into the disjointed narrative of Ballarat’s Theatre Royal. Its ultimate failure demonstrates how dominant community based entertainment became in Ballarat from the 1860s onwards, effectively crushing prospects for mid-range professional theatre. There is value in considering the evolution of the theatre’s lifespan and its possible legacy effects. The connection between historical consciousness and the performing arts culture of by-gone days offers potential to reveal specks of cross-relevance for regional Australian theatrical offerings today.In the BeginningThe proliferation of entertainment venues in Ballarat East during the 1850s was a consequence of the initial discovery of surface alluvial gold and the ongoing success of deep-lead mining activities in the immediate area. This attracted extraordinary numbers of people from all over the world who hoped to strike it rich. Given the tough nature of life on the early gold diggings, most disposable income was spent on evening entertainment. As a result, numerous venues sprang into operation to cater for demand. All were either canvas tents or makeshift wooden structures: vibrant in socio-cultural activity, however humble the presentation values. It is widely agreed (Withers, Bate and Brereton) that noteworthy improvements occurred from 1856 onwards in the artistry of the performers, audience tastes, the quality of theatrical structures and living standards in general. Residents began to make their exit from flood and fire prone Ballarat East, moving to Ballarat West. The Royal was the first substantial entertainment venture to be established in this new, affluent, government surveyed township area. Although the initial idea was to draw in some of the patronage which had flourished in Ballarat East, Brereton (14) believed “There can be no doubt that it was [primarily] intended to attract those with good taste and culture”. This article will contend that how society defined ‘good taste’ turned out to be problematic for the Royal.The tumultuous mid-1850s have attracted extensive academic and popular attention, primarily because they were colourful and politically significant times. The period thereafter has attracted little scholarly interest, unless tied to the history of surviving organisations. Four significant structures designed to incorporate theatrical entertainment were erected and opened in Ballarat from 1858 onwards: The Royal was swiftly followed by the Mechanics Institute 1859, Alfred Hall 1867 and Academy of Music 1874-75. As philosopher Albert Borgmann (41) highlighted, the erection of “magnificent settings in which the public could gather and enjoy itself” was the dominant urban aspiration for cultural consumption in the nineteenth century. Men of influence in Victorian cities believed strongly in progress and grand investments as a conscious demonstration of power, combined with Puritan vales, teetotalism and aggressive self-assertiveness (Briggs 287-88). At the ceremonial laying of the foundation stone for the Royal on 20 January 1858, eminent tragedian, Gustavos Brooke, announced “… may there be raised a superstructure perfect in all its parts, and honourable to the builder.” He proclaimed the memorial bottle to be “a lasting memento of the greatness of Ballarat in erecting such a theatre” and philosophised that “the stage not only refines the manners, but it is the best teacher of morals, for it is the truest and most intelligible picture of life. It stamps the image of virtue on the mind …” (Star, “Laying” 21 Jan. 1858). These initial aspirations seem somewhat ambitious when viewed with the benefit of hindsight. Ballarat’s Theatre Royal opened in December 1858, ironically with Jerrold’s comedy ‘Time Works Wonders’. The large auditorium holding around 1500 people “was crowded to overflowing and was considered altogether brilliant in its newness and beauty” by all in attendance (Star, “Local and General” 30 Dec. 1858). Generous descriptions abound of how splendid it was, in architectural terms, but also in relation to scenery, decorations and all appointments. Underneath the theatre were two shops, four bars, elegant dining rooms, a kitchen and 24 bedrooms. A large saloon was planned to be attached soon-after. The overall cost of the build was estimated at a substantial 10,000 pounds.The First Act: 1858-1864In the early years, the Royal was deemed a success. The pleasure-seeking public of Ballarat came en masse and the glory days seemed like they might continue unabated. By the early 1860s, Ballarat was known as a great theatrical centre for performing arts, its population was famous both nationally and internationally for an appreciation of good acting, and the Royal was considered the home of the best dramatic art in Ballarat (Withers 260). Like other theatres of the 1850s diggings, it had its own resident company of actors, musicians, scenic artists and backstage crew. Numerous acclaimed performers came to visit and these were prosperous and happy times for the Royal’s lively theatrical community. As early as 1859, however, there was evident rivalry between the Royal and the Mechanics Institute, as suggested on numerous occasions in the Ballarat Star. As a multi-purpose venue for education and the betterment of the working classes, the latter venue had the distinct advantage of holding the moral high ground. Over time this competition increased as audiences decreased. As people shifted to family-focussed entertainments, these absorbed their time and attention. The transformation of a transient population into a township of families ultimately suffocated prospects for professional entertainment in Ballarat. Consumer interest turned to the growth of strong amateur societies with the establishment of the Welsh Eisteddfod 1863; Harmonic Society 1864; Bell Ringers’ Club 1866 and Glee and Madrigal Union 1867 (Brereton 38). By 1863, the Royal was reported to have “scanty patronage” and Proprietor Symonds was in financial trouble (Star, “News and Notes” 15 Sep. 1864). It was announced that the theatre would open for the last time on Saturday, 29 October 1864 (Australasian). On that same date, the Royal was purchased by Rowlands & Lewis, the cordial makers. They promptly on-sold it to the Ballarat Temperance League, who soon discovered that there was a contract in place with Bouchier, the previous owner, who still held the hotel next door, stating that “all proprietors … were bound to keep it open as a theatre” (Withers 260-61). Having invested immense energy into the quest to purchase it, the Temperance League backed out of the deal. Prominent Hotelier Walter Craig bought it for less than 3,000 pounds. It is possible that this stymied effort to quell the distribution of liquor in the heart of the city evoked the ire of the Protestant community, who were on a dedicated mission “to attack widespread drunkenness, profligacy, licentiousness and agnosticism,” and forming an interdenominational Bible and Tract Society in 1866 (Bate 176). This caused a segment of the population to consider the Royal a ‘lost cause’ and steer clear of it, advising ‘respectable’ families to do the same, and so the stigma grew. Social solidarity of this type had significant impact in an era in which people openly demonstrated their morality by way of unified public actions.The Second Act: 1865-1868The Royal closed for renovations until May 1865. Of the various alterations made to the interior and its fittings, the most telling was the effort to separate the ladies from the ‘town women’, presumably to reassure ‘respectable’ female patrons. To this end, a ladies’ retiring room was added, in a position convenient to the dress circle. The architectural rejuvenation of the Royal was cited as an illustration of great progress in Sturt Street (Ballarat Star, “News and Notes” 27 May 1865). Soon after, the Royal hosted the Italian Opera Company.However, by 1866 there was speculation that the Royal may be converted into a dry goods store. References to what sort of impression the failing of theatre would convey to the “old folks at home” in relation to “progress in civilisation'' and "social habits" indicated the distress of loyal theatre-goers. Impassioned pleas were written to the press to help preserve the “Temple of Thespus” for the legitimate use for which it was intended (Ballarat Star, “Messenger” and “Letters to the Editor” 30 Aug. 1866). By late 1867, a third venue materialised. The Alfred Hall was built for the reception of Ballarat’s first Royal visitor, the Duke of Edinburgh. On the night prior to the grand day at the Alfred, following a private dinner at Craig’s Hotel, Prince Alfred was led by an escorted torchlight procession to a gala performance at Craig’s very own Theatre Royal. The Prince’s arrival caused a sensation that completely disrupted the show (Spielvogel, Papers Vol. 1 165). While visiting Ballarat, the Prince laid the stone for the new Temperance Hall (Bate 159). This would not have been required had the League secured the Royal for their use three years earlier.Thereafter, the Royal was unable to reach the heights of what Brereton (15) calls the “Golden Age of Ballarat Theatre” from 1855 to 1865. Notably, the Mechanics Institute also experienced financial constraints during the 1860s and these challenges were magnified during the 1870s (Hazelwood 89). The late sixties saw the Royal reduced to the ‘ordinary’ in terms of the calibre of productions (Brereton 15). Having done his best to improve the physical attributes and prestige of the venue, Craig may have realised he was up against a growing stigma and considerable competition. He sold the Royal to R.S. Mitchell for 5,500 pounds in 1868.Another New Owner: 1869-1873For the Saturday performance of Richard III in 1869, under the new Proprietor, it was reported that “From pit to gallery every seat was full” and for many it was standing room only (Ballarat Star, “Theatre Royal” 1 Feb. 1869). Later that year, Othello attracted people with “a critical appreciation of histrionic matters” (Ballarat Star, “News and Notes” 19 July 1869). The situation appeared briefly promising. Unfortunately, larger economic factors were soon at play. During 1869, Ballarat went ‘mad’ with mine share gambling. In 1870 the economic bubble burst, and hundreds of people in Ballarat were financially ruined. Over the next ten years the population fell from 60,000 to less than 40,000 (Spielvogel, Papers Vol. 3 39). The last surviving theatre in Ballarat East, the much-loved Charles Napier, put on its final show in September 1869 (Brereton 15). By 1870 the Royal was referred to as a “second-class theatre” and was said to be such bad repute that “it would be most difficult to draw respectable classes” (Ballarat Star, “News and Notes” 17 Jan. 1870). It seems the remaining theatre patrons from the East swung over to support the Royal, which wasn’t necessarily in the best interests of its reputation. During this same period, family-oriented crowds of “the pleasure-seeking public of Ballarat” were attending events at the newly fashionable Alfred Hall (Ballarat Courier, “Theatre Royal” June 1870). There were occasional high points still to come for the Royal. In 1872, opera drew a crowded house “even to the last night of the season” which according to the press, “gave proof, if proof were wanting, that the people of Ballarat not only appreciate, but are willing to patronise to the full any high-class entertainment” (Ballarat Courier, “Theatre Royal” 26 Aug. 1872). The difficulty, however, lay in the deterioration of the Royal’s reputation. It had developed negative connotations among local temperance and morality movements, along with their extensive family, friendship and business networks. Regarding collective consumption, sociologist John Urry wrote “for those engaged in the collective tourist gaze … congregation is paramount” (140). Applying this socio-cultural principle to the behaviour of Victorian theatre-going audiences of the 1870s, it was compelling for audiences to move with the masses and support popular events at the fresh Alfred Hall rather than the fading Royal. Large crowds jostling for elbow room was perceived as the hallmark of a successful event back then, as is most often the case now.The Third Act: 1874-1878An additional complication faced by the Royal was the long-term effect of the application of straw across the ceiling. Acoustics were initially poor, and straw was intended to rectify the problem. This caused the venue to develop a reputation for being stuffy and led to the further indignity of the Royal suffering an infestation of fleas (Jenkins 22); a misfortune which caused some to label it “The Royal Bug House” (Reid 117). Considering how much food was thrown at the stage in this era, it is not surprising that rotten debris attracted insects. In 1873, the Royal closed for another round of renovations. The interior was redesigned, and the front demolished and rebuilt. This was primarily to create retail store frontage to supplement income (Reid 117). It was reported that the best theatrical frontage in Australasia was lost, and in its place was “a modestly handsome elevation” for which all play-goers of Ballarat should be thankful, as the miracle required of the rebuild was that of “exorcising the foul smells from the old theatre and making it bright and pretty and sweet” (Ballarat Star, “News and Notes” 26 Jan. 1874). The effort at rejuvenation seemed effective for a period. A “large and respectable audience” turned out to see the Fakir of Oolu, master of the weird, mystical, and strange. The magician’s show “was received with cheers from all parts of the house, and is certainly a very attractive novelty” (Ballarat Courier, “Theatre Royal” 29 Mar. 1875). That same day, the Combination Star Company gave a concert at the Mechanics Institute. Indicating the competitive tussle, the press stated: “The attendance, however, doubtless owing to attractions elsewhere, was only moderately large” (Courier, “Concert at the Mechanics’” 29 Mar. 1875). In the early 1870s, there had been calls from sectors of society for a new venue to be built in Ballarat, consistent with its status. The developer and proprietor, Sir William Clarke, intended to offer a “higher class” of entertainment for up to 1700 people, superior to the “broad farces” at the Royal (Freund n.p.) In 1875, the Academy of Music opened, at a cost of twelve thousand pounds, just one block away from the Royal.As the decade of decreasing population wore on, it is intriguing to consider an unprecedented “riotous” incident in 1877. Levity's Original Royal Marionettes opened at the Royal with ‘Beauty and the Beast’ to calamitous response. The Company Managers, Wittington & Lovell made clear that the performance had scarcely commenced when the “storm” arose and they believed “the assault to be premeditated” (Wittington and Lovell in Argus, “The Riot” 6 Apr. 1877). Paid thuggery, with the intent of spooking regular patrons, was the implication. They pointed out that “It is evident that the ringleaders of the riot came into the theatre ready armed with every variety of missiles calculated to get a good hit at the figures and scenery, and thereby create a disturbance.” The mob assaulted the stage with “head-breaking” lemonade bottles, causing costly damage, then chased the frightened puppeteers down Sturt Street (Mount Alexander Mail, “Items of News” 4 Apr. 1877). The following night’s performance, by contrast, was perfectly calm (Ballarat Star, “News and Notes” 7 Apr. 1877). Just three months later, Webb’s Royal Marionette pantomimes appeared at the Mechanics’ Institute. The press wrote “this is not to be confounded, with the exhibition which created something like a riot at the Theatre Royal last Easter” (Ballarat Star, “News and Notes” 5 July 1877).The final performance at the Royal was the American Rockerfellers’ Minstrel Company. The last newspaper references to the Royal were placed in the context of other “treats in store” at The Academy of Music, and forthcoming offerings at the Mechanics Institute (Star, “Advertising” 3 July 1878). The Royal had experienced three re-openings and a series of short-term managements, often ending in loss or even bankruptcy. When it wound up, investors were left to cover the losses, while the owner was forced to find more profitable uses for the building (Freund n.p.). At face value, it seemed that four performing arts venues was one too many for Ballarat audiences to support. By August 1878 the Royal’s two shop fronts were up for lease. Thereafter, the building was given over entirely to retail drapery sales (Withers 260). ReflectionsThe Royal was erected, at enormous expense, in a moment of unbridled optimism, after several popular theatres in Ballarat East had burned to the ground. Ultimately the timing for such a lavish investment was poor. It suffered an inflexible old-fashioned structure, high overheads, ongoing staffing costs, changing demographics, economic crisis, increased competition, decreased population, the growth of local community-based theatre, temperance agitation and the impact of negative rumour and hear-say.The struggles endured by the various owners and managers of, and investors in, the Royal reflected broader changes within the larger community. The tension between the fixed nature of the place and the fluid needs of the public was problematic. Shifting demographics meant the Royal was negatively affected by conservative values, altered tastes and competing entertainment options. Built in the 1850s, it was sound, but structurally rigid, dated and polluted with the bacterial irritations of the times. “Resident professional companies could not compete with those touring from Melbourne” by whom it was considered “… hard to use and did not satisfy the needs of touring companies who required facilities equivalent to those in the metropolitan theatres” (Freund n.p.). Meanwhile, the prevalence of fund-raising concerts, created by charitable groups and member based community organisations, detracted from people’s interest in supporting professional performances. After-all, amateur concerts enabled families to “embrace the values of British middle class morality” (Doggett 295) at a safe distance from grog shops and saloons. Children aged 5-14 constituted only ten percent of the Ballarat population in 1857, but by 1871 settler families had created a population in which school aged children comprised twenty-five of the whole (Bate 146). This had significant ramifications for the type of theatrical entertainments required. By the late sixties, as many as 2000 children would perform at a time, and therefore entrance fees were able to be kept at affordable levels for extended family members. Just one year after the demise of the Royal, a new secular improvement society became active, holding amateur events and expanding over time to become what we now know as the Royal South Street Society. This showed that the appetite for home-grown entertainment was indeed sizeable. It was a function that the Royal was unable to service, despite several ardent attempts. Conclusion The greatest misfortune of the Royal was that it became stigmatised, from the mid 1860s onwards. In an era when people were either attempting to be pure of manners or were considered socially undesirable, it was hard for a cultural venue to survive which occupied the commercial middle ground, as the Royal did. It is also conceivable that the Royal was ‘framed’, by one or two of its competitor venues, or their allies, just one year before its closure. The Theatre Royal’s negative stigma as a venue for rough and intemperate human remnants of early Ballarat East had proven insurmountable. The Royal’s awkward position between high-class entrepreneurial culture and wholesome family-based community values, both of which were considered tasteful, left it out-of-step with the times and vulnerable to the judgement of those with either vested interests or social commitments elsewhere. This had long-term resonance for the subsequent development of entertainment options within Ballarat, placing the pendulum of favour either on elite theatre or accessible community based entertainments. The cultural middle-ground was sparse. The eventual loss of the building, the physical place of so much dramatic energy and emotion, as fondly recalled by Withers (260), inevitably contributed to the Royal fading from intergenerational memory. The telling of the ‘real story’ behind the rise and fall of the Ballarat Theatre Royal requires further exploration. If contemporary cultural industries are genuinely concerned “with the re-presentation of the supposed history and culture of a place”, as Urry believed (154), then untold stories such as that of Ballarat’s Theatre Royal require scholarly attention. This article represents the first attempt to examine its troubled history in a holistic fashion and locate it within a context ripe for cultural analysis.ReferencesBate, Weston.
