Abstract:
This article puts under scrutiny the religious manifestations in Eliot’s devotional poetry and the meditative questions that he raises. To do so, it limits the scope of my analytical reading to one of his well-known meditative poems, “Ash-Wednesday.” I shall start with a theoretical analysis of his famous article, “Religion and Literature” and argue for the presence of its milestone ideas in Eliot’s poetry taking “Ash-Wednesday as a case study.” The study also discerns Eliot’s renunciation of the main tenets of Romanticism which he made use of before his conversion.

Abstract:
In his 1916 dissertation, Eliot asserted that individuals were locked into finite centers and that all knowledge was epistemologically relative, but he also believed that finite centers could be transcended through language. In the essay "Lancelot Andrewes,'" Eliot identified Andrewes's "relevant intensity," a method very close to nonsensical verse. Eliot used Andrewes's Word and the impersonality of nonsense verse in Ash Wednesday. The Word, God's logos, embodied the Virgin Mary as its source, and allowed Eliot to transcend the finite center through language. Ultimately, Eliot philosophically empowered the feminine as the source of the Word. Though failing to fully empower the earthly Lady in part II of Ash Wednesday, Eliot did present a philosophical plan for transcending the finite center through language.

Full text
Abstract:
This paper delves into the realms of tragedy, memory and representation. Drawing upon the phenomenon of the Phantom Limb and extending it towards a theory of Phantom Bodies, various artworks - literary, theatrical and visual - are examined. After the conflagration of the terrorist attack, how are these absences grieved over and remembered through artistic representation? The essay examines this question by positioning itself amongst the scarred landscapes of post-September 11 New York and suicide bombings in Israel (2000-2006). Furthermore, it investigates whether humanity can be restored in the aftermath of an event in which certain individuals have sought to eradicate it. The fragmentation of the affected body in these scenarios is understood as further complicating processes of grief and remembrance. Artists who reject political polemic and engage with the dimensions of human loss are seen to have discovered means of referring to the absence caused by the act of terrorism. Three such recurring representations present themselves: ash and remnants, presence/absence and memory building. Phantom Bodies are perceived as simultaneously functioning as a reminder of the event itself, insisting upon the response of bearing witness, and as a symbol of the overwhelming power of humanity. Challenges arise when individuals or sections of the affected society deem these artworks to be inappropriate or explicit. Works considered include: Neil LaBute's play The Mercy Seat, Sigalit Landau's art installation The Country, Jonathan Safran Foer's Extremely Loud & Incredibly Close, Spike Lee's 25th Hour, Daniel Libeskind's architectural plans for the World Trade Center site, Eric Fischl's sculpture 'Tumbling Woman', Honor Molloy's autodelete://beginning dump of physical memory and A.B.Yehoshua's A Woman in Jerusalem. The accompanying play, Tales of Ash: A diptych for the theatre, is set in Melbourne, New York and Tel Aviv and deals with life in the face of and after terror. It veers between naturalism, poetic monologue and the epic. Tales of Ash contains two plays. The first centres on Mia, a young sculptor living in New York, who loses both her lover and her creativity on September 11. Upon returning to her home in Melbourne, she finds familial bonds still entwined with guilt and family trauma. The second play revolves around Ilana and Benny, two people living in Tel Aviv, who find themselves suddenly thrust together after a devastating bombing. As they attempt to resume rhythms of life, in the face of all the inherent ferocity of a modern existence in Israel, the struggle between The Ash Woman and The Ash Takers escalates.

Full text
Abstract:
This paper focuses on two aspects of the recipe minilect: clause-initial adverbials and object and determiner ellipsis in the translation from English into Swedish. The aim of the study is to find general tendencies on how clause-initial adverbials are translated and how this affects the information structure. In addition, the occurrence of object and determiner ellipsis in translations is studied, to see if there are differences between English and Swedish. Based on a theoretical background by Hasselgård (1997) the translation of clause-initial adverbials is identified and structured, according to Hasselgård’s (1997) model of word order correspondence. The structures are then studied quantitatively, through different examples in English and Swedish, and with regards to Lindquist’s (1989) definition of adverbial placement. The theoretical background for the study on object and determiner ellipsis is mainly based on the work by Nordman (1994), Hultman (2003) and Biber et al (1999). The occurrence of ellipsis is identified and then studied quantitatively. The results show that different kinds of word order restrictions govern the translation of clause-initial adverbials and that changes in adverbial placement can affect the information structure. The occurrence of object ellipsis is somewhat higher in the present study than in the analyzed parallel texts, possibly due to influence from the ST. Due to Swedish rules on definiteness, there is a low occurrence of determiner ellipsis in the TT.

Abstract. Replacing cement with fly ash has recently created huge popularity among the construction field because of its huge production, efficient resources and sustainability aspect. This study is made to determine the High-Volume fly-ash concrete (HVFC) performance by adding additives. The general used concrete mixture is prepared by proportioning fly ash (40-50%) as a replacement. The concrete specimen was found to have better compressive strengths and hence, passed the strength tests. By incorporating additive Nano-SiO2 and superplasticizer the following compression, flexural rigidity, splitting tensile strength and elasticity modulus were observed in the specimen to establish the cement and fly ash bond. The concrete performance mix with replacement fly ash at different percent was found to have good compressive strength during test and stayed undamaged during the entire period of exposure.

Abstract. For reducing the cost in bitumen roads and also increasing the efficiency of bituminuous roads, varieties of materials are used for improving the road by using coconut shell charcoal ash as fillers in the flexible pavement. In the literature work, the main descriptive of the work is to compare the results with different percentages of coconut shell charcoal ash in bitumen. The Properties of the coconut shell charcoal possesses are resistance to breaking the materials, absorbing the heat, moisture content of surface, grading, heating and synthetic resin glues which is important for pavement of bitumen roads. Therefore, its stability of Marshall stability test and flow value in Marshall stability and air void ratio are obtained. So that it can be compared with different modified percentage as 4.5%, 5%, 5.5% and 6% in test on Bitumen. From this test we can establish so that it can be useful as a substitute as a coconut shell charcoal ash for improving the strength, quality and durability of bitumnious road. For carrying out these experiments, Marshall stability test is used for obtaining better results for normal mix and modified mix for the bitumen.

Full text
Abstract:
Since the 70’s, nothing substantially new has been published in the Gas Turbine Community about the hot corrosion by vanadium and its inhibition, after the “inhibition orthodoxy” based on the formation of magnesium vanadate, was established. However, the experience acquired since the late 80’s with Heavy Duty Gas Turbines burning ash-forming fuels in Southern China, shows that the combustion of very contaminated fuels does not entail corrosion nor abundant ash-deposit on gas turbines buckets. Analyses of deposits collected from gas turbines fired with these crude oils showed that the ash-deposit contains a large amount of nickel. These new facts led to revisit the role played by nickel and envisage its possible inhibiting action against the vanadium-induced hot corrosion. A thorough review of the literature on the vanadium-induced corrosion have been carried out, and the study of the nickel effects with respect to magnesium effects on the ash deposit have been performed Results show that nickel presents an interesting way to substitute magnesium for the inhibition of vanadium-induced hot corrosion. The advantages of nickel with respect to magnesium are to be efficient at a low Ni/V ratio, to produce less abundant, less adherent ash and to act, to some extent, as a self-cleaning agent for the blades of the turbine.

"A Systematic Study on Physical and Mechanical Properties of No-Fine Concrete with Additives." In Recent Advancements in Geotechnical Engineering. Materials Research Forum LLC, 2021. http://dx.doi.org/10.21741/9781644901618-24.

Full text
Abstract:
Abstract. No-fine concrete (also called as pervious concrete or porous concrete) is a lightweight concrete made up of primary binder and coarse aggregates with little or no sand. Due to the reduced amount or absence of fines, it produces large number of voids which improves permeability to greater extent. Hence this type of concrete can be used in pavements and in parking lots. The literature review is carried out to study the physical and mechanical properties of no-fine concrete with additives. Various reports were collected and studied about variation in physical and mechanical properties of pervious concrete with different additives. Additives may be either mineral additives (fly ash, silica fumes, rice husk ash etc..,) or chemical additives (plasticizers, super plasticizers, retarders etc..,). Our project involved the utilization of recycled coarse aggregates, fly ash and rice husk in no-fine concrete. After this study, it was concluded that ‘upon the addition of additives, it increases permeability by decreasing its strength and vice-versa’. Balancing its permeability and strength remains challenging.

Full text
Abstract:
Ash deposition on turbine blade surfaces is studied in this work using a particle deposition model. The model involves the three main processes: particle transport to the blade surface particle sticking at the surface and particle detachment from the surface. The model is used to investigate the effect of ash particle deposition on the flow field through turbine cascades. The surface velocity and the downstream total pressure coefficient are calculated for the clean and the fouled blade profiles and used in this investigation. The profile of the clean blade is chosen from the literature for which flow field measurements are available. The two dimensional compressible flow field is solved for the clean blade using the RNG k-ε turbulence model with the two layer zonal model for the near-wall region. The results are compared to the experimental data. The flow field is solved at the conditions expected in modern gas turbines. The deposition distribution on the blade surface is calculated during three periods of 12 operating hours each assuming inlet particle concentration as 100 ppmw. The fouled blade profile is predicted after each period. Then the flow field and deposition calculations are repeated to account for the time-dependent particle deposition. The flow field is calculated for the fouled blade after operating hours and investigated using the experimental data and the numerical calculations of the clean blade. The profile loss of the fouled blade is also predicted and compared to that of the clean blade.

Full text
Abstract:
This study is focused on volcanic ash ingestion in aircraft engines, that can lead to slow but constant deterioration in engine performance and engine failure because of the mechanical damages to the wall surface. In particular the particles that impact on blades surfaces cause erosion damage and permanent losses in engine performance. Aircraft engine fans could be severely damaged by the ash flow.. In order to clarify the erosion phenomenon the fan has been simulated through the general-purpose CFD code and the numerical simulations were performed using the Reynolds–Averaged Navier–Stokes (RANS). After validating the numerical modeling of the flow without erosion by comparisons with experimental data in literature, a surface injection of a discrete phase has been introduced in order to evaluate particle ingestion of volcanic ash. This phenomenon is a typical gas-particle two-phase turbulent flow and a multi-physics problem where the flow field, particle trajectory and wall deformation interact with among others. A wide experimental investigation has been carried out on an ash sample from Etna volcano. In particular a sieve analysis to obtain particles dimensional distribution and an analysis of SEM images to calculate particles shape factor. These data were used to modeling the particle injection in the CFD model. The numerical investigation was aimed to clarify the effects of particle erosion and to evaluate the change of the flow field in the case of eroded blades. By erosion rate patterns, the eroded mass was estimated and it was used to model the eroded geometry, by a user routine implemented in the dynamic mesh module of the code. So the performances of the damaged fan were estimated and compared with the baseline geometry without erosion.

"Co-Combustion of Coal With RDF and Biomass: Prevention of Chlorine Deposition by Using Coal Ash Alkali Absorption Ability." In 18th International Conference on Fluidized Bed Combustion. ASMEDC, 2005. http://dx.doi.org/10.1115/fbc2005-78120.

Full text
Abstract:
The co-combustion of fossil fuels with CO2-neutral fuels is an attractive way both to decrease CO2 emissions in energy production and to use fuel synergies which decrease each other’s undesirable properties. This paper presents a new approach to understand and predict the chlorine deposition tendency in the co-combustion of coal with biomass and RDF. This novel approach combines the results from deposit analysis with flue gas emission measurement and advanced fuel characterization methods. The experiments were carried out in a 0.1 MW circulating fluidized bed reactor. Two different types of bituminous coal (South African and Polish) were co-fired with RDF, demolition wood and bark. The traditional way to predict risk for chlorine deposition, the fuel S/Cl molar ratio, and the safe limit molar ratio &gt; 4 for biofuels were shown to be inadequate. The mineral kaolinite in coal ash was found to be able to capture alkalis and, in most cases, more effectively than sulphur compounds. The alkali capture capability of coal sulphur is quickly consumed due to reactions with calcium compounds. Furthermore, the ability of SO2 to sulfate alkali chlorides were found to be weaker than presented in the literature. Thus in many cases it is only kaolinite that keeps Cl away from the deposit. New index to predict chlorine deposition tendency were introduced: the reactive (Al+Si)/fuel Cl molar ratio. The results showed a good correlation between the chlorine concentration in the deposit and the new index. The reactive (Al+Si)/fuel Cl molar ratio higher than 8–10 was found to prevent chlorine to deposit. The new approach for better understanding and preventing of chlorine deposition promotes the co-combustion of coal with biomass and RDF by introducing new synergy benefits.

Full text
Abstract:
One of the pulverized coal fired thermal power plants in India intended to find the root cause of frequent boiler tube failures in three 210 MW units. Operation &amp; Maintenance history and feedback from plant O&amp;M team revealed that economizer tube failure was a frequent cause of forced outage. The plant under study used CFS (continuous fin surface) economizer with staggered tube arrangement in the 210 MW units. CFS staggered tube economizers originally appealed to many plant designers because the tortuous path created for the flue gas, enhanced heat absorption and the fins could capture heat and transfer it to the tubing. This made the CFS economizer less costly and easy for installation in a relatively small space. There is increasing use of lower quality high ash coals over the past few decades. Due to this fact an advantage of the CFS economizer design became a disadvantage. The narrow spacing in the tubes proved more susceptible to plugging and fly ash erosion. Literature study and the root cause analysis suggested that CFS staggered arrangement of economizer could be one of the prominent reason of failure of economizer tube bundle due to fly ash erosion. Flue gas flow simulation also highlighted that there is increase in velocity of flue gases across the economizer. A bare tube in-line configuration in place of existing CFS economizer was an alternative. To recommend an alternate economizer as solution, the merits of an in-line bare tube economizer were studied. Bare tubes arranged in-line are most conservative in hostile environments with high ash content, are least likely to plug, and have the lowest gas-side resistance per unit of heat transfer. A bare tube in-line economizer that can replace the existing finned tube economizer in the available space while meeting the existing design &amp; performance parameters is recommended. An attempt was made to model &amp; analyze the new economizer using computational fluid dynamics (CFD) tools in order to get firsthand experience and validate the results obtained using manual calculations. With limited computational resources and not so fine meshing, the performed CFD model analysis showed the expected trend but did not completely match the results.

Abstract:
Under certain greenhouse gas (GHG) regulation scenarios, older coal-fired units may be faced with the prospect of shutdown before reaching the end of their useful life. Repurposing this existing asset for 100% biomass fuel is a more efficient use of capital than compared to building a new stand-alone unit. Biomass co-firing is an alternative for an owner to consider to address GHG regulation impacts on older coal-fired power boilers and the growing demands of pending legislation. “Direct” co-firing is a baseline approach where finely divided biomass is injected directly into the boiler furnace. Direct co-firing experience is typically less than 5% heat rate, and technical upper limits have been described in EPRI literature (1) as approximately 10% of boiler heat. Direct co-firing also does not enhance the opportunity to co-fire biomass with natural gas. Direct biomass co-firing may require extensive renovations and emissions/particulate control devices. “Indirect” co-firing is an alternative process that mitigates process risk by first converting the biomass into a fuel gas and then cleaning this gas to remove alkali and chloride contaminants prior to combustion in the power boiler furnace. Indirect co-firing may be a superior approach from an operations perspective because it protects against forced outages and repair costs expected with direct co-firing (2). Gas cleaning to remove alkali metals from the fuel gas prior to combustion reduces process risk by reducing fouling and slagging potential. Removing chloride from the fuel gas dramatically reduces the corrosion potential. Beyond reducing process risk, separating biomass ash before combustion retains the value in separate co-product ash streams, as it prevents intermingling with the coal ash. This paper describes technical and economic considerations for indirect co-firing, contrasted with direct co-firing approaches. The renewable energy ratio of a co-fired unit could be significantly increased by employing biomass gasification of the solid fuel with gas cleanup, in contrast to process risks, added emissions control costs, and technical limitations of direct co-firing of the solid biofuel.
