Abstract:

Joseph Lister – the largest English surgeon and scientist, the founder of antiseptics, President of the Royal society of surgeons, a member of the house of lords. Joseph Lister was born on 5 apr 1827 in England. In 1844 he graduated from high school, and in 1852, the medical faculty of the University of London and was appointed resident assistant College University hospital. The first scientific work of Lister was published in 1852 and was dedicated to the structure of the iris of the eye and its muscles. Soon Lister began working in the clinic of Professor George. Syme in Edinburgh and published lectures, devoted primarily to ophthalmology. In 1855 he became a member of the Royal College of surgeons and is a Professor in the George. Saimaa. In 1858 Lister became a surgeon of the Royal hospital in Edinburgh and at the same time began to read a course of surgery at the University. On 9 March 1860 he was appointed Professor of surgery in Glasgow. In 1867 in the journal "Lancet" published articles Lister, in which he argued the idea that wound infection is called a living beginning, introduced from the outside; was presented to combat surgical infection, comprising treating hand surgeon, surgical field and instruments, disinfection of the air by atomization of a solution of carbolic acid. In 1869 Lister was transferred to the surgical clinic in Edinburgh, and in 1877 he was given the chair of clinical surgery at king's College London. In 1884 Joseph Lister was given the title of baronet, from 1895 to 1900 he was President of the Royal society of surgeons; in 1897 appointed a member of the house of lords. In 1892 he was 65 years old and, according to the law, he had to leave the Department at the Royal College. Joseph Lister was made an honorary member of numerous universities and scientific societies, was awarded the Royal medal (1880), medal of Comenius (1877), albert (1894), Copley (1902); the order of merit (1902). Died Joseph Lister, on 10 February 1912 in Walmer. In honor of Joseph Lister has been named a genus of bacteria Listeria (Listeria), he is on the English postage stamp, issued in 1966.

Abstract:

My E-Diary for Activities and Lifestyle (MEDAL), a web-based application, was developed to assess the diets of children. This study examined the validity of school recess meals reported by children on MEDAL, using meal photography as the reference. Recess meals were photographed by trained researchers, and food items and portion sizes of recess meals reported on MEDAL were compared to recess meal photos. Validity was assessed by percentages of match, omission and intrusion for food items and percentages of the match, underestimation and overestimation for portion sizes. The Mann–Whitney test and the Wilcoxon matched-pairs signed-rank test examined if sex, school and day of recording influenced the validity of food item reporting. We found that participants (n = 33, aged 10–11 years) recalled 60.2% of food items consumed at recess accurately (matches); omissions (24.6%) were more common than intrusions (15.2%). Omissions tended to be side dishes, and intrusions tended to be high-calorie items. Sex, school and day of recording did not influence validity. For food portion sizes, 58.3% of items were accurately reported. Overestimations (33.3%) were more common than underestimations (8.3%). In conclusion, these children were able to report food items consumed during school recess meals using MEDAL, albeit with limitations on the degree of accuracy.

Abstract:

A personable teenager with Down's syndrome became a Canadian cause célèbre a few months ago when University Hospital in Edmonton, Alberta, denied him a position on the organ transplantation waiting list. Terry Urquart lacked “reasonable” intelligence, hospital officials said, a criterion for all transplant candidates at that hospital. Protests by the boy's family, and by groups active in the cause of those with developmental disabilities, became well-photographed stories on the nightly television news and in the nation's newspapers. It did not hurt the Urquart cause one bit that the 17-year-old teenager had won a gold medal in skiing at the International Special Olympics.

Abstract:

It is commonly held that the major functional features of the human foot (e.g. a functional longitudinal medial arch, lateral to medial force transfer and hallucal (big-toe) push-off) appear only in the last 2 Myr, but functional interpretations of footbones and footprints of early human ancestors (hominins) prior to 2 million years ago (Mya) remain contradictory. Pixel-wise topographical statistical analysis of Laetoli footprint morphology, compared with results from experimental studies of footprint formation; foot-pressure measurements in bipedalism of humans and non-human great apes; and computer simulation techniques, indicate that most of these functional features were already present, albeit less strongly expressed than in ourselves, in the maker of the Laetoli G-1 footprint trail, 3.66 Mya. This finding provides strong support to those previous studies which have interpreted the G-1 prints as generally modern in aspect.

Full text

Abstract:

Geomorphic, stratigraphic, and sedimentologic evidence obtained from Quaternary sediments near Jasper, Alberta, is used to reconstruct depositional environments in the vicinity of two former confluent valley glaciers. Sedimentation occurred mainly in the valley centre in a pre-existing river channel. Lateral ice-marginal sedimentation along the inset valley walls was important during both the advance and the retreat stages. Prior to and during glacial advance, horizontally stratified gravels, sands, and silts were deposited in a braided stream. Near the valley bottom, diamictons containing trough-shaped sand lenses were deposited by subsequent proglacial debris flows and intermittent fluvial activity. At higher stratigraphic positions, outwash deposits confined to the valley wide are unconformably overlain by massive diamicton, interpreted as subglacial till, deposited as ice began to override the area. The diamicton grades towards the valley side into ice-contact debris deposited at the margins of the expanding glacier by water and sediment flows from the ice surface. Glaciers eventually overrode the entire area. During deglaciation, thick sequences of normally faulted, steeply dipping sand, gravel, and clast-rich diamicton were deposited in a kame terrace west of Jasper townsite. The orientation of bedding and faults and the nature of the sediments indicate they were derived from, and deposited in contact with, a linear belt of stagnating, debris-covered ice that extended along the valley centre east of Jasper. It is postulated that the stagnating ice originated from a well-developed medial moraine and debris septum that formed at the confluence of the large Athabasca and Miette valley glaciers. The knob-and-kettle topography, which eventually developed in the valley centre, was obscured by glaciofluvial and fluvial activity. A linear chain of kettle lakes remains as evidence of the possible existence of the moraine. Kettle chains and hummocky topography, formed in the positions of both medial and lateral moraines, may be relatively common geomorphic features in glaciated mountain valleys.

Abstract:

There is increasing global recognition of the effects of large scale land disturbance by wildfire on a wide range of water and ecosystem services. In 2003, the Lost Creek wildfire burned a contiguous area of 21,000 ha on the eastern slopes of the Rocky Mountains in southern Alberta. This disturbance had a significant and prolonged impact on the water quantity and quality of downstream river reaches and reservoirs in the Oldman watershed. Previous research in this watershed demonstrates that dissolved metal concentrations in rivers draining burned landscapes were 2 to 15 times greater than in unburned reference streams (Silins et al. 2009a). Currently there is no information on the effects of wildfire on the bioaccumulation and toxicity of sediment-associated metals in fire-impacted streams in Alberta. This study was designed to evaluate the linear downstream disturbance effects of wildfire in the Crowsnest River located in southern Alberta. The toxicity and bioaccumulation of particulate-associated metals from wildfire impacted tributaries to the Crowsnest River on freshwater amphipod Hyalella azteca were evaluated. Phillips samplers were deployed to collect suspended solids in streams draining burned zone impacted by the Lost Creek wildfire and reference (unburned) zones within the area. Metal toxicity and bioaccumulation were determined in the laboratory by exposing the epi-benthic freshwater amphipod Hyalella azteca to particulates collected from the Crowsnest River. A metal effects addition model (MEAM) was used to assess the impact of metal mixtures and to predict chronic mortality (Norwood et al. 2013). Increased concentrations of Al, Ba, Co, Cr, Mn and Zn were found in the tissues of H. azteca exposed to particulates from burned watersheds in comparison to the unburned watersheds. H. azteca mean survival was similar when exposed to the particulates samples from both burned and unburned sites indicating that 9 years after this landscape disturbance, there was little impact due to the wildfire. However, at burned site (B1), the observed survival was lower than survival predicted by MEAM. The data suggests that factors other than the metals examined in this study were influencing the survival of H. azteca. The concentrations of sediment-associated metals have decreased in the nine years since the wildfire, and minimal metal toxicity was observed in H. azteca. Although metal toxicity in H. azteca was minimal 9 years after the Lost Creek Fire, the short term effects of wildfire on metal toxicity remain largely unknown. In addition, other factors such as burn severity, stream size and hydroclimatic conditions can influence the effects of wildfire on abundance and diversity of aquatic invertebrates (Minshall et al. 2001). Therefore, the influences of those factors on metal toxicity as a result of wildfire should be rigorously assessed in future studies.

This chapter refers to William Shipley, who had benefited from the aid of the Royal Society of Arts' first two presidents, Viscount Folkestone and Lord Romney, for his visions to be taken seriously and initiate the Great Exhibition. It points out how the Society capitalised on the credit it got for initiating the Great Exhibition in the 1950s and used that reputation to push for reforms. The chapter talks about the “Albert Medal” that commemorates the death of Prince Albert and was awarded to people who had done much to aid arts, manufactures, and commerce. It mentions Rowland Hill as the first recipient of the Albert Medal for his campaign to create the Penny Postage system. It also explains how the awarding of the Albert Medal each year allowed the Society to associate itself with household names or recognise its own activists, such as Henry Cole or John Alexander Milne.

Abstract:

Heavy metal contamination has gained popularity worldwide due to their persistent nature in the environment, on the top of that non-biodegradable nature makes its accumulation easy to toxic levels. Understanding the nature of contamination has become a major concern before heavy metals deteriorate the quality of soil; to diagnose heavy metal pollution suitable indices are required. Microbial indices gaining importance because of their sensitive nature towards change in surrounding, which is the imperative quality required to select microbes as environmental indicators. Albeit enough literature is present related to this topic but the information is scattered so role of this chapter is imperative. The chapter will be helpful for the reader to provide a thorough understanding of merits and demerits of microbiological indices for heavy metal contaminated and restituted soils. The changes in microbiological indices and their mechanism of response towards heavy metal stress are effectively summarized. Research gap and future needs of microbial diagnosis of heavy metal contaminated soils are discussed.

Full text

Abstract:

This chapter describes the fundamentals of metal corrosion in relation to thermodynamics and kinetics. The chapter is so titled, because corrosion of metal is thermodynamically favourable. Moreover, it impacts negatively on economy and safety. Industries expend a substantial percentage of their budgets on corrosion control, and lose revenue due to corrosion damage. Effects of corrosion on industrial and public infrastructure cannot be overemphasized. Several accidents in the transportation and recreational industries have been linked to corrosion of metallic parts of respective gadgets. Some of these accidents are utterly catastrophic and fatal. Therefore, corrosion, albeit its thermodynamic favouability, is not desired by man. Metals corrode as a way of minimizing energy contents. Active metals are more stable in combined forms such as oxides, sulphides, and hydroxides, even though these forms are less useful to man. It appears the “price” to pay for extracting the pure forms of these metals from their ores is corrosion. This chapter presents fundamentals of thermodynamics and kinetics of metal corrosion, with emphasis on aqueous medium. It promises to serve as an introductory chapter for corrosion science students and as a concise material for tutors.

Full text

Abstract:

The pyrometallurgical methods of the recovery of various critical metals have been established. Certain pyrometallurgical approaches for niobium (Nb) and tantalum (Ta) extraction have been studied and investigated by several researchers. For instance, the conventional reduction of Nb mineral or Nb2O5 to Nb metal has been conducted over the decades. Albeit, the success level of this process, it however involves the consumption of lots of energy, high cost of equipment/equipment maintenance, somewhat low Nb and Ta recovery and limited effectiveness on low grade minerals; and thus, considered cost intensive and inefficient. In addition, the inadequacies of pyrometallurgical extraction of these metals from their complex, low grade mineral ores due to its difficulty and large energy requirement in melting the elemental impurities and gangue minerals have been a major concern. On this premise therefore, the study will provide insights into recent pyrometallurgical techniques of Nb and Ta extraction as well as associated factors and challenges.

Abstract:

Actualmente la base de datos de Cambridge alberga cerca de un millón cien mil estructuras cristalinas; lo cual muestra un crecimiento exponencial de la cristalografía en las últimas décadas. Dentro de estas estructuras, existen 60,000 redes Metal-Orgánicas (MOFs), las cuales incluyen a los BioMOFs, cuya relevancia consiste en usar ligantes naturales, ser de bajo costo de producción y de fácil adquisición. Debido a los enlaces de coordinación que las generan, estas estructuras pueden producir cristales con características muy puntuales, de allí el interés del escalamiento de su síntesis mediante procesos completamente industrializados. Sus características dependen de los tipos de reacciones utilizadas para su síntesis. No obstante, se han tenido avances significativos respecto a los parámetros: mezcla de solventes, mezcla de metales y ligantes, moduladores, pH, rampas de temperatura, geometrías de coordinación de los metales, entre otros. Por estas razones, en este capítulo se hace una revisión bibliográfica sobre la síntesis de los MOFs con metales de transición, ácidos carboxílicos y adenina como ligantes, y la aplicación de los mismos, como la separación de gases producidos durante el efecto invernadero. Así mismo, se mencionan los resultados obtenidos en el Centro Conjunto de Investigación en Química Sustentable (CCIQS) UAEM-UNAM y en Laboratorio de Investigación y Desarrollo de Materiales Avanzados (LIDMA) de la UAEMex, por el grupo de investigación de Estructuras Metal-Orgánicas.

Abstract:

Seiji Iwasa of the Toyohashi University of Technology devised (Adv. Synth. Catal. 2012, 354, 3435) a water-soluble Ru catalyst for enantioselective intramolecular cyclopropanation that could be separated from the product and recycled by simple water/ether extraction. Minoru Isobe of the National Tsing Hua University combined (Org. Lett. 2012, 14, 5274) the Nicholas and Hosomi-Sakurai reactions to close the cyclobutane ring of 4. Kazunori Koide of the University of Pittsburgh established (Tetrahedron Lett. 2012, 53, 6637) that the activity of a Ru metathesis catalyst, shut down by the presence of TBAF, could be restored by the inclusion of TMS2O. Jan Streuff of Albert-Ludwigs-Universität Freiburg demonstrated (Angew. Chem. Int. Ed. 2012, 51, 8661) that the enantiomerically pure Brintzinger complex mediated the reductive cyclization of 7 to 8. Huw M.L. Davies of Emory University prepared (J. Am. Chem. Soc. 2012, 134, 18241) the cyclopentenone 11 by the Rh-mediated addition of 10 to 9 followed by elimination. Christophe Meyer and Janine Cossy of ESPCI ParisTech showed (Angew. Chem. Int. Ed. 2012, 51, 11540) that the Rh-mediated rearrangement of 12 to 13 proceeded with substantial diastereocontrol. Jian-Hua Xie and Qi-Lin Zhou of Nankai University observed (Org. Lett. 2012, 14, 6158) that the enantioselective hydrogenation of 14 followed by Claisen rearrangement established the cyclic quaternary center of 17 with high stereocontrol. Ken Tanaka of the Tokyo University of Agriculture and Technology devised (Angew. Chem. Int. Ed. 2012, 51, 13031) the Rh-mediated addition of the enyne 18 to 19 to give the highly substituted cyclohexene 20. Daesung Lee of the University of Illinois at Chicago showed (Chem. Sci. 2012, 3, 3296) that the ring-opening/ring-closing metathesis of 21 delivered 22 with high diastereocontrol. Andreas Speicher of Saarland University cyclized (Org. Lett. 2012, 14, 4548) 23 to 24 with significant atropisomeric induction. Erick M. Carreira of the Eidgenössische Technische Hochschule Zürich effected (J. Am. Chem. Soc. 2012, 134, 20276) the polycyclization of racemic 25 to 26 with high enantiomeric excess. Medium rings are often the most difficult to construct, because of the inherent congestion across the forming ring. Phil S. Baran of Scripps/La Jolla effected (Angew. Chem. Int. Ed. 2012, 51, 11491) the cyclization of 27 to 28 as a single dominant diastereomer.

Abstract:

Fabrication of micro and nanoscale electronic components has become increasingly demanding due to device and interconnect scaling combined with advanced packaging and assembly for electronic, aerospace and medical applications. Recent advances in additive manufacturing have made it possible to fabricate microscale, 3D interconnect structures but heat transfer during the fabrication process is one of the most important phenomena influencing the reliable manufacturing of these interconnect structures. In this study, optical absorption and scattering by three-dimensional (3D) nanoparticle packings are investigated to gain insight into micro/nano heat transport within the nanoparticles. Because drying of colloidal solutions creates different configurations of nanoparticles, the plasmonic coupling in three different copper nanoparticle packing configurations were investigated: simple cubic (SC), face-centered cubic (FCC) and hexagonal close packing (HCP). Single-scatter albedo (ω) was analyzed as a function of nanoparticle size, packing density, and configuration to assess effect for thermo-optical properties and plasmonic coupling of the Cu nanoparticles within the nanoparticle packings. This analysis provides insight into plasmonically enhanced absorption in copper nanoparticle particles and its consequences for laser heating of nanoparticle assemblies.

Full text

Abstract:

Gas foil bearings (GFBs) enable efficient, reliable and maintenance free operation of high-power-density microturbomachinery (&lt; 200 kW). High speed rotors supported on bump-type GFBs, however, are prone to show large-amplitude subsynchronous motions albeit reaching limit cycle performance. Presently, commercial GFBs are simply modified to introduce a mechanical preload that induces a hydrodynamic wedge to generate more load support and direct stiffnesses. Three metal shims inserted under the bump strip layers and in contact with the bearing housing create a multiple lobe clearance profile at a very low cost. Shaft speed coastdown measurements reveal the rotordynamic performance of a rotor supported on original GBFs and (modified) shimmed GFBs. The later GFBs determine a raise in the rotor-bearing system natural frequency, as expected, and also act to delay the onset speed of large-amplitude subsynchronous motions. Predictions of imbalance response implementing linearized bearing force coefficients are in good agreement with measured amplitudes of synchronous response for both GFB configurations, original and modified.

Abstract:

Parasitic secondary flows (seals’ leakage) in centrifugal compressors and gas and steam turbines represent a substantial loss in efficiency and power delivery with an increase in specific fuel consumption. Labyrinth seals are the most common and inexpensive means of reducing secondary leakage, albeit wearing out with operation and thereby penalizing performance and even affecting rotordynamic stability. The novel Hydrostatic Advanced Low Leakage (HALO) seal is an all-metal seal with flexibly supported shoes that enable clearance self-control to effectively reduce leakage, in particular for operation with high pressure ratios and at high surface rotor speeds. This paper presents leakage tests with hot air (max. 300°C) conducted in a test rig holding a labyrinth seal and a HALO seal, both of similar diameter, axial length and clearance. The novel seal leaks much less than the labyrinth seal as the supply/discharge pressure ratio (Ps/Pa) increases. The leakage reduction is ∼50% for (Ps/Pa) < 2 and continuously dropping to 70% for (Ps/Pa) > 3.0. Thus, the savings in leakage are maximized for operation with a high pressure differential. Leakage measurements with a rotor spinning to a maximum speed of 2,700 rpm (surface speed ∼ 24 m/s) produce a slight decrease in leakage for both seals. Characterization of seal leakage in terms of a flow factor removes the effect of temperature and supply pressure; the labyrinth seal showing a constant flow factor for (Ps/Pa) > 2. Application of the novel seal technology will aid to increase system efficiency by reducing leakage and will extend maintenance intervals since it eliminates wear of components.

Full text

Abstract:

This paper describes a multi-year PRCI research program that investigated the local buckling (or wrinkling) of onshore pipelines with metal-loss corrosion. The dependence of local buckling resistance on wall thickness suggests that metal-loss defects will considerably reduce such resistance. Due to the lack of experimental data, overly conservative assumptions such as a uniform wall thickness reduction over the entire pipe circumference based on the defect depth have been used in practice. The objective of this research work was to develop local buckling criteria for pipelines with corrosion defects. The work related to local buckling was carried out in three phases by C-FER and the University of Alberta. The first phase included a comprehensive finite element analysis to evaluate the influence of various corrosion defect features and to rank key parameters. Based on the outcome of Phase 1 work, a test matrix was developed and ten full-scale tests were carried out in Phase 2 to collect data for model verification. In Phase 3, over 150 parametric cases were analyzed using finite element models to develop assessment criteria for maximum moment and compressive strain limit. Each criterion includes a set of partial safety factors that were calibrated to meet target reliabilities selected based on recent research related to pipeline code development. The proposed criteria were applied to in-service pipeline examples with general corrosion features to estimate the remaining load-carrying capacity and to assess the conservatism of current practice.

Full text

Abstract:

A novel process entitled “Sediments Remediation Phase Transition Extraction” (SR-PTE) is being developed for a simultaneous removal of both heavy metals and organic pollutants from contaminated sediments or sludge. The process uses partially miscible solvent mixtures, where one of the components is water. By heating the mixture above a certain temperature, a single phase is formed. This allows the organic solvent, containing an appropriate chelating agent, to penetrate the wetted sediment voids and efficiently extract simultaneously the organic and heavy metal pollutants. The phase separation, occurring during the cooling stage, is fast and allows the pollutants to propagate and concentrate in the lighter organic phase, leaving the sediments and the lower aqueous phase practically clean. The SR-PTE technology was tested on authentically polluted river sediments and on heavily contaminated sludge from a waste-water treatment plant. The extraction efficiency was found to improve by the phase transition cycle induced by temperature variation (about twice than that obtained when the extraction was carried out isothermally). Additionally, with the induced phase transition, the formation of stable emulsions is prevented albeit the presence of natural surfactants in the treated media. The process was tested on lab scale and bench-scale reactor. No significant effects of the process up-scaling from lab to bench scale were observed.

Abstract:

A comparison of currently available codes for assessment of fatigue crack growth, including ASME (America Society of Mechanical Engineers) SEC. XI, FKM (Forchungskuratorium Maschinenbau) guideline, WES (Japan Welding Engineering Society) 2805, BS7910 and JSME (The Japan Society of Mechanical Engineers), was carried out by paying attention to the suitability of application and the easiness to obtain the parameters, based on fatigue crack growth data of Cr-Ni-Mo-V steel welded joints. Results showed that fatigue crack growth curves provided by the FKM or WES were good choice when few inputs were at hand while the curves in the BS7910, JSME and ASME were recommended for precise estimation. It was indicated that the assessment of welded joints solely by fatigue crack growth behavior at base metal part and the assessment of fatigue crack growth for the aged condition by as-received one both resulted in non-conservativeness, albeit dependent on the range of stress ratios, R. A new bilinear form of fatigue crack growth model independent of R was developed based on transition point occurred in the near-threshold regime. This constituted the bilinear approach to fatigue assessment, and thus contributed to the optimization of fatigue assessment in the near-threshold regime.

Abstract:

Abstract Lithium-ion batteries are a proven energy storage device which continue to gain market share across a wide range of applications. However, the safety of these devices is still a major factor in many applications. In failures which result in thermal runaway, a series of chemical reactions are initiated which produce a large quantity of gas and heat. The pressure and temperature inside the battery rise sharply and may cause fire or explosion. The lithium-ion battery vent cap is a key safety device used in 18650 format cells to prevent an energetic failure of the metal casing. In this paper, the cap structure and venting parameters of three cap designs are analyzed. The venting parameters investigated were the open flow area and discharge coefficient. Open flow area through different components of the cap assembly were measured using 3D x-ray scans. A new experimental apparatus was used to measure mass flowrate and pressure ratio across the battery cap, which allowed calculation of discharge coefficient. Results indicate that discharge coefficients follow the same trend as a sharp-edged orifice, albeit at a reduced magnitude due to the more tortuous flow path. A semi-empirical model is proposed to simulate mass flow through the battery cap.

Abstract:

Many industrial plant sites have assembly torque tables for standard ASME B16.5 flanges as part of their internal procedures for bolted flanged joints. It is common for end-users to change gasket materials and gasket designs to reduce costs and/or improve reliability or as processes evolve and change. As environmental awareness and regulations continue to increase, it is important to understand the different levels of tightness that can be achieved from various gasket technologies. Gaskets do not seal equally at the same assembly load. All bolted flanged joints sealed with a gasket have some emissions rate, albeit some vanishingly small on very tight joints. The tightness parameter has an inverse relation to leakage; the tighter a joint, the less leakage it has. The less leakage, the less emissions result. Where emissions monitoring is intense, tighter gasket technologies are preferred. These tighter technologies are often more expensive. Where emissions are less a concern, river water as an example, more economical gasket selections are preferred. This paper explores gasket tightness performance of a number of materials and construction types common for industrial and power use. Material classes that will be explored include compressed fiber, polytetrafluorethylene (PTFE), flexible graphite (FG), and flexible vermiculite (FV). Construction types that will be explored include sheet materials, composites with metal inserts (flat or corrugated), grooved metal with soft facings (“kammprofile”), and spiral wound gaskets. For the purposes of comparison, an example assembly torque table will be used. The table includes ASME B16.5 Class 150 flanges, sizes ½” through 24”, using A105 carbon steel flanges and high strength A193 B7 fasteners. With a better understanding of the general capability of a gasket class — the end user can more quickly select gasket materials and constructions suitable for a particular application. This work follows and expands earlier work done with more limited flange sizes. [1]

Full text

Abstract:

L-shaped composite structures are increasingly replacing metal ribs and box structures especially in recent civil aerospace structures and wind turbine blades. Delamination of these L-shaped composite laminates occur by interlaminar opening stresses at the curved region under perpendicular loading to one arm. In this study, delamination at the curved region is studied experimentally and computationally by using a simplified model material consisting of two L-shaped polycarbonate plates bonded together. The effect of precrack size at the curved region on the initiation and propagation of delamination under loading perpendicular to one of the arms is studied. Experimental observations are carried out using photoelasticity to visualize the isochromatic stress patterns in the model. Finite element analysis (ABAQUS) is carried out using static (implicit) analysis during elastic loading followed by dynamic (explicit) analysis during crack growth in conjunction with a bilinear cohesive zone model. For precracks smaller than 40mm, a sudden drop in load-displacement plot is observed corresponding to dynamic crack growth at 80 m/s crack tip speed from the corner to the arms. Afterwards, a generally monotonic increase in load-displacement behavior is observed albeit with a lower stiffness corresponding to continued stable crack growth. For larger pre-cracks, load-displacement increases monotonically even after crack initiates with stable stick-slip type crack growth. These two regimes of crack growth are consistent with the observations of Wimmer et al (2009) on cross-ply composite L-beams.

Abstract:

In the early days, there were significant limitations to the build size of laser powder bed fusion (L-PBF) additive manufacturing (AM) machines. However, machine builders have addressed that drawback by introducing larger L-PBF machines with expansive build volumes. As these machines grow, their size capability approaches that of directed energy deposition (DED) machines. Concurrently, DED machines have gained additional axes of motion which enable increasingly complex part geometries—resulting in near-overlap in capabilities at the large end of the L-PBF build size. Additionally, competing technologies, such as binder jet AM and metal material extrusion, have also increased in capability, albeit with different starting points. As a result, the lines of demarcation between different processes are becoming blurred. Internal Boundaries of Metal Additive Manufacturing: Future Process Selection examines the overlap between three prominent powder-based technologies and outlines an approach that a product team can follow to determine the most appropriate process for current and future applications.

Full text

Abstract:

A comprehensive study of Mississippi Valley-type base-metal deposits across the Canadian Cordillera was done to compare and contrast their features. Extensive dissolution of host rocks is followed by multiple generations of dolomite cements from early, low-temperature, fine-grained to coarser, higher temperature types that overlap with Zn-Pb sulfide minerals; late-stage calcite occludes residual porosity. Dolomite is generally chemically stoichiometric, but ore-stage types are often rich in Fe (&amp;lt;1.3 weight per cent FeO) with small sphalerite inclusions. Sphalerite-hosted fluid inclusions record ranges for homogenization temperatures (77-214°C) and fluid salinity (1-28 weight per cent equiv. NaCl±CaCl2). These data suggest fluid mixing with no single fluid type related to all sulfide mineralization. In situ secondary ion mass spectrometry (SIMS) generated delta-18OVSMOW values for carbonate minerals (13-33 permille) reflect dolomite and calcite formation involving several fluids (seawater, basinal, meteoric) over a large temperature range at varying fluid-rock ratios. Sphalerite and pyrite SIMS delta-34SVCDT values vary (8-33 permille) but in single settings have small ranges (&amp;lt;2-3 permille) that suggest sulfur was reduced via thermochemical sulfate reduction from homogeneous sulfur reservoirs. Collectively, the data implicate several fluids in the mineralizing process and suggest mixing of a sulfur-poor, metal-bearing fluid with a metal-poor, sulfide-bearing fluid.
