Abstract:
AbstractThis paper reports the finding of the first, known study of a Caribbean community's views on pit bulls. College students (375) provided their perceptions on a number of issues related to pit bull guardianship ("ownership"). Age, sex, and dog-owning status influenced some of their views. They saw pit bulls as being different from other dogs, but not all supported banning pit bulls. Some results reinforced the stereotypes associated with pit bull ownership: Most pit bull owners were under 19 years of age, and older respondents were more likely than younger ones to support a ban on pit bulls. Why different subgroups of respondents held their views would be a useful avenue for future research.

Abstract:
According to The Humane Society of the United States from 2006 to 2008 there were more than 3,000 pit bulls removed from dogfighting rings. The majority of surviving dogs were euthanized upon confiscation by authorities. The purpose of this research was to examine the possible impact of Michael Vick’s dogfighting case on print media coverage of pit bull-type dogs. The research questions were whether the extensive coverage of his dogfighting charges would change how media portray these dogs, and whether the issue of dogfighting would become a more widely-covered topic. The research process included a literature review of scholarly works written about pit bulls, and a qualitative analysis of articles from The New York Times, The Wall Street Journal, and USA Today published one year before and after the Vick case broke, using “pit bull” as the key phrase. Articles were divided into different categories depending on the contextual use of the term “pit bull.” Findings were based on the analysis of those categories. The results indicated positive portrayals of pit bulls and discussions of dogfighting were primarily isolated to the coverage of Vick’s case and dogs. The more than 200 other recorded raids on dogfighting rings that same year went unmentioned, but six stories about aggressive pit bull-type dogs were covered. This indicates media coverage of pit bulls did not change. Media can learn there is more to cover than limiting the focus on celebrity dogfighters and the cliché of pit bulls as vicious. These changes in coverage could lead to an overall positive change in the public’s perception of pit bull-type dogs.

Abstract:
AbstractThe term Pit bull is widely used. However, is it assigned a specific definition, or is it associated with overly inclusive and contradictory meanings? At the beginning of the 1900s, dogs identified as Pit bulls were known for their love of children. Media sensationalism has contributed to a shift in perceptions of Pit bulls from favorite companion animals to problem nonhuman animals. Thus, the process of constructing “problem animals” is examined. A qualitative study was conducted to explore what the term Pit bull represents for a sample of fifty-six adults. The data collection tool was the Personal Meaning Map. Respondents seemed to have vague and conflicting definitions of Pit bulls. For some, they are gentle companions, but for others they are gang-related status symbols. For some, Pit bulls represent one breed, whereas for others they represent many breeds. Finally, they were perceived to be both victims of cruelty and predators.

Abstract:
A visual clinical gait analysis is useful, however, it may overlook small, but important, details about the movement, as well as differences between the normal and pathological locomotion. The branch of mechanics that describes the spatial and temporal components of motion is called kinematics, providing quantitative data regarding linear and angular motion. The objective of this study was to establish kinematic gait data of healthy American Pit Bull Terriers and to contribute to the understanding of the locomotion. We evaluated the articular and pelvic angles, and the spatiotemporal variables for walking and trotting from eleven dogs with no previous history of joint and musculoskeletal diseases. Twenty reflective markers were positioned at the anatomical points of interest. The animals walked and trotted in a linear space, led by the same researcher. The kinematic data were collected through optoelectronic cameras and analysed by motion analysis software. The movements analysed during the gait phases were the flexion, extension, range of motion (ROM), angle at the moment of the support phase, stride length and velocity. Comparing the angles between walking and trotting, there were more expressive differences for the pelvic limb joints. There was no difference between the left and right sides at all of the joint angles of the pelvic limbs during walking and trotting. Therefore, the movement of the pelvic limb is symmetrical in both trotting and walking. Our results present reference values for healthy American Pit Bull Terriers, having clinical relevance for studies of dogs with musculoskeletal diseases.

Abstract:
This article explores the aesthetic and cultural connections between the hyper-masculinization inherent to hip hop culture (and particularly to gangsta rap), the pit bull dog breed, and dogfighting. Building on recent scholarship that has identified the racial and racist assumptions underlying the pit bull controversy, I provide further evidence and arguments on how the highly racialized and genderized hip hop discourses inoculate the pit bull body and suffuse it with multiple meanings reminiscent of America’s traumatic encounter with otherness. As a palimpsest that attests to both mainstream and countercultural explorations of racialized masculinities, the pit bull body is made to “perform” its role as both an agent and a victim within the nation’s compulsive need to control and monitor the “other.”

Abstract:
A análise clínica da marcha, observação visual, é útil, porém pouco precisa, enquanto a análise quantitativa compreende uma avaliação mais eficiente, calculando variáveis de distâncias e variáveis angulares. O ramo da mecânica que descreve os componentes espaciais e temporais do movimento chama-se cinemática. O objetivo do presente estudo foi estabelecer dados cinemáticos da marcha de cães hígidos da raça American Pit Bull Terrier e contribuir para a compreensão do movimento da locomoção. Foram avaliados os ângulos articulares dos membros torácicos e pélvicos, e variáveis espaço-temporais para caminhada e trote. Foram estudados 11 cães, idade entre 2 a 6 anos, com escore de condição corporal entre 4 a 6, de ambos os sexos. Os animais estudados não apresentavam histórico prévio de doenças articulares e musculoesqueléticos. Cada cão teve 20 marcadores reflexivos posicionados nos pontos anatômicos de interesse. Os animais caminharam e trotaram dentro de um espaço linear (sete metros), conduzido pelo mesmo pesquisador. Os dados cinemáticos foram coletados com o emprego de 6 câmeras e analisadas por um programa de análise de movimento. Os movimentos analisados durante as fases da marcha foram: flexão (diminuição do ângulo articular), extensão (aumento do ângulo articular), amplitude de movimento, ângulo no instante da fase de apoio, comprimento e velocidade de passada. Ao comparar os ângulos entre caminhada e trote, verificou-se diferenças mais expressivas para as articulações dos membros pélvicos. Não houve diferença entre os lados esquerdo e direito em todos os ângulos articulares dos membros pélvicos durante a caminhada e trote. Portanto, o movimento do membro pélvico mostra-se simétrico tanto ao trote quanto à caminhada, fato relevante para estudos de cães portadores de doenças musculoesqueléticas.

The kinematic data were collected using 6 cameras and analyzed by a motion analysis program. The movements analyzed during gait phases were: flexion (decrease of joint angle), extension (increase of joint angle), range of motion, angle at the instant of the support phase, length and speed of the course. Comparing the angles between walking and trotting, there were more expressive differences for the pelvic limbs joints. There was no difference between the left and right sides at all joint angles of the pelvic limbs during walking and trotting.

Abstract:
The American Pit Bull Terrier, otherwise known as the “pit bull”, has become one of the world‟s most notorious dog breeds, due to its perceived aggressive temperament and relation to dogfighting and gangs. This paper looks to examine the history of the breed and how its creation and involvement with dogfighting influenced the general public‟s negative perception of the breed throughout the end of the 20th century. By understanding how the breed‟s violent history influenced its negative reputation, it can be determined how the breed became targeted by breedspecific legislation. Additionally, this paper addresses the history of breed-specific legislation, and how it specifically relates to the American Pit Bull Terrier, and how the stereotypes of the breed influenced the enactment of breed-specific laws. This paper will also address the issues with breed-specific legislation and why such laws are not beneficial for the community, and will also introduce alternatives that are safer and more reasonable for the community and the dogs.

Abstract:
Bull trout are a fish species listed as threatened under the Endangered Species Act.Historically, they ranged from Northern California at the southernmost extent, into Canada at the northern most extent, and east into Nevada and Montana. Bull trout are highly migratory and require large, unfragmented habitats to persist and are thus highly susceptible to human induced land-use practices. The goal of my thesis was to obtain a better understanding of bull trout movement patterns in the Walla Walla River, Washington using complimentary techniques; Passive Integrated Transponder (PIT)technology and otolith microchemistry. PIT tags can be injected into a fish body cavity, similar to how pets are “chipped”, and as the fish swim through antennas placed in the river, their location and movements are be documented.Otolith microchemistry is a technique that is similar to analysis of tree rings. The otolith, a hard bony structure of a fish’s ear, develops over a lifetime and as the rings of the otolith are created the chemical signature in the water in which they live is recorded and can be compared to chemical makeup of water samples collected through the river system. Using these two techniques, I found that the age or size of a fish and the season are important factors to explain both a fish’s movements and where in the river a fish might be located at a given time. Knowing at what size, age and season a fish is attempting to migrate allows managers to provide the best possible river conditions (e.g., temperatures, flow) to allow for unimpeded migrations to occur and to foster conservation and recovery of bull trout populations.

Abstract:
Três cães machos adultos da raça Pit Bull foram utilizados com o intuito de avaliar o efeito da suplementação de triptofano na atividade elétrica cerebral e taxa glicêmica. Os tratamentos foram: A) Dieta base + veículo com placebo (controle); B) Dieta base + veículo com 1,11g de triptofano. Inicialmente os animais passaram por doze dias de fornecimento do tratamento A, destes, cinco dias foram destinados a colheita dos dados. Após três dias de descanso teve início o período de 12 dias de fornecimento do tratamento B, com o aumento de um dia de colheita. Para a colheita de EEG foi utilizado o registro bipolar, sendo o sinal colhido numa freqüência de amostragem de 120 Hz por um período de 20 minutos por dia de colheita. Utilizou-se um glicosímetro portátil para mensurar a glicemia nos tempos 0, 15, 30, 45 minutos, relacionados com o período destinado ao manejo de colheita de EEG. A suplementação de triptofano diminuiu a energia das bandas de freqüências beta, teta, alfa e delta, permitindo sugerir uma modificação na atividade elétrica cerebral. Não houve efeito significativo do fornecimento de triptofano suplementar sobre a glicemia dos cães utilizados neste experimento.
Three adults male Pit Bulls dogs were housed with the intention of evaluating the effects of tryptophan supplementation on brain electrical activity and glicemic curve. The treatments were: A) Basic Diet + Placebo (control); B) Basic Diet + 1,11 g of tryptophan. First the animals were kept for 12 days using the A treatment, with five days of data collecting. After three days off they were kept for 12 days using the B treatment, but with an addition of one day of data collecting. The EEG collecting was made using a bipolar register, and the signal was collected on a 120 Hz sampling frequency for 20 minutes per collecting day. The blood glucose was measured using a portable blood glucose meter on 0, 15, 30 and 45 minutes, related to the EEG collecting period. The Tryptophan supplementation decreased the energy signals of the beta, theta, alpha and delta frequencies, which suggests some modification on the brain electrical activity. There was no effect of the tryptophan supplementation on the glicemic curve.

Abstract:
This research expected pit bull coverage to become more violent and more negative in the wake of the Vick trial, so a content analysis was conducted of "pit bull" mentions in the year 2006 and in 2009. The first year was intended to provide a comparison for this study, documenting the pit bull's mediated depiction before the Vick trial. Mentions from 2009 were intended to represent the aftermath of this trial, pinpointing its effects on the breed's mediated depiction. Tonal mentions of the breed were almost 17 percentage points more negative in 2009 than in 2006. Violent mentions increased by a more than 20 percentage points during this period. Topical selections also shifted, and 2009 coverage chose to focus more on pit bull attacks than in 2006. This research proposes a theory of collateral fallout for mediated subjects, and pit bulls, as a brand, have suffered from this fallout.

Abstract:
Reclamation on the Cardinal River and Gregg River coal mines includes the construction of mine pit lakes connected to stream environments. Key physical, chemical and biological parameters of these “truck and shovel” lakes and their streams were investigated, and hypotheses regarding ecosystems and populations were tested. Findings include: Sphinx Lake and Pit Lake CD exhibit meromictic (partial-mixing) tendencies, but still function in a similar fashion to shallower, natural sub-alpine lakes. Elevated selenium concentrations as high as 16 ug/g (dry weight) were recorded in Rainbow trout (Oncorhynchus mykiss) eggs taken from gravid Sphinx Lake and Pit Lake CD fish. Potential detrimental effects associated with the bioaccumulation of selenium on fish reproduction were not observed. Stream water temperatures downstream of Sphinx Lake and Pit Lake CD were significantly warmer than in inlet streams and streams without pit lakes. Streambed concretions caused by calcite precipitation were documented and found to affect portions of the upper Gregg River basin. Remediation of this concretion is important for sustainability of trout populations. Aquatic communities including fish, invertebrates, zooplankton and aquatic plants are present in these pit lake systems. Athabasca Rainbow trout populations are self-propagating (spawning at the outlets) with higher densities downstream than there were prior to lake reclamation. The development of sub-alpine mine-pit lakes connected to the stream environment appears to be an appropriate and beneficial reclamation technique in this area.

Abstract:

Dogs categorized as pit bulls are entangled with American sociocultural and psychological dynamics, and alternately imagined as noble, vicious, and sweet. Depth psychology holds that untended unconscious dynamics overwhelm situations and manifest in undesired ways such as violence and oppression. This research explored the unconscious dynamics in pit bull phenomena and asked whether archetypal understandings of these phenomena can promote compassion, social justice, and well-being for dogs and humans. Employing a hermeneutic methodology with a depth psychological lens, this research sought an archetypal understanding of pit bull fighting, breed-specific legislation (BSL), negative breed-based stereotypes, and pit bull rescue and advocacy through hermeneutic dialogues with texts representing these phenomena. Findings showed that the worlds of White dogfighters and game dog breeders contain a complex array of archetypal elements, including archetypes of Warrior, Hero, Wise Old Man, and Magician, and themes of initiation and alchemy. These worlds are also sites for productions of White American heteromasculine personae. Other findings showed that BSL, negative breed stereotypes, and pit bull rescue and advocacy represent transformations of the pit bull image through alchemical stages of destructive nigredo and purifying albedo. These stages showed how the pit bull image emerges from White social anxieties and is employed to reestablish White comfort. An integrated rubedo stage of the pit bull image, in which all of these dynamics are made conscious, is promoted to support social justice and well-being for dogs and humans.

Full text
Abstract:
One of the most important properties of an explosive is its velocity of detonation (VOD). It is essential that the explosive should detonate at its optimum rate and release sufficient detonation pressure to get good fragmentation under the existing field conditions. The main objectives of this research study are to investigate the effects of explosive type, blast hole diameter, and degree of confinement on the VOD of bulk ANFO and bulk emulsion in Kumtor Open Pit Gold Mine. In this study, the continuous resistance wire method is employed to measure in-situ VOD of both bulk ANFO and bulk emulsion. The VOD values are measured for different hole diameters and under different confinements for both explosives. The ideality of bulk ANFO and bulk emulsion is calculated by comparing the in-situ measured VOD&rsquo
s and their ideal detonation values. It is found that the VOD of both explosives increases as the blast hole diameter and the degree of confinement increases. In addition to this, VOD of bulk ANFO decreases when it gets wet in the blast hole. Another finding is that, proportion of bulk emulsion ingredients has influence on its VOD. This research study provides a good understanding to use suitable explosive in existing rock conditions in Kumtor Open Pit Gold Mine.

<i>Abstract</i>.—To track individuals in situ, over 12 million salmon and trout have been marked with passive integrated transponder (PIT) tags in the Columbia River Basin, USA. However, few studies have examined long term tag retention as well as tag effects on juvenile salmon and trout. We marked juvenile coho salmon <i>Oncorhynchus kisutch</I> (<I>N</I> = 207), steelhead (anadromous rainbow trout) <i>O. mykiss</I> (<I>N</I> = 221), cutthroat trout <i>O. clarkii</I> (<I>N</I> = 202) and bull trout <i>Salvelinus</I> <i>confluentus</I> (<I>N</I> = 180) with 12, 19, or 23 mm PIT tags and examined tag retention, survival, growth, and physiological performance over a six month period in a laboratory environment. PIT tag retention rates were high for coho salmon (100%), steelhead (95%), cutthroat trout (97%), and bull trout (99%), regardless of tag size. Survival was also high for coho (99%), steelhead (99%), cutthroat trout (97%), and bull trout (88%) and did not vary among tag sizes. Short term individual growth rates for coho salmon marked with 12 mm tags were significantly higher than those marked with 19 mm and 23 mm PIT tags. Likewise, steelhead trout individual growth rates were lower for fish marked with 23 mm PIT tags followed by 19 and 12 mm tags. Conversely, long-term growth rates were positive and not affected by tag size. There were no significant effects of tag size or marking on coho gill Na+, K+, -ATPase activity (μmol ADP x mg protein<sup>–1</sup> h<sup>–1</sup>) and plasma osmolality (μmol kg<sup>–1</sup>) or bull trout hepatosomatic indices. Our study suggests that marking juvenile salmonids with PIT tags results in high retention with little effect upon their survival, growth, and important physiological indicators regardless of tag size in a laboratory environment.

Abstract:
The tuning of the gains of a controller with proportional-integral-derivative (PID) actions has been prevalent in the industry. The adjustment of these gains in PID controllers is often determined by classical methods, such as Ziegler-Nichols, and trial and error. However, these methods fail to deliver satisfactory performance and often do not meet specific project demands because of the inherent complexity of industrial processes, such as plant parameter variations. To solve the tuning problem in highly complex industrial processes, a controller adjustment method based on the internal product of PID terms is proposed, and a propagation matrix (PM) is generated by the numerator coefficients of the plant transfer function (TF). In the proposed method, each term of the PID controller is influenced by each of the numerator and the denominator coefficients. Mathematical models of practical plants, such as unloading and resumption of bulk solids by car dumpers and bucket wheel resumption, were employed to evaluate the proposed method. The obtained results demonstrated an assertive improvement in the adjustment gains from PID actions, thereby validating it as a promising alternative to conventional methods.

Abstract:
This chapter argues that the Christian “tragical conscience,” as described in the preceding chapter, was a conscience that demanded its own “cleansing” (catharsis) and clarified moral vision, which further relied on the cultivation, psychologically and existentially, of a whole panoply of tragical emotions that enriched Christian response to real-life tragedies. The assessment here of the development of a Christian “tragical pathos” draws from Martha Nussbaum’s work on the “moral intelligence” of emotions in Hellenistic philosophy and from Robert Kaster’s identification of “emotional scripts” in Greco-Roman moral philosophy and ethics. The bulk of this chapter is devoted to early Christian reworking or “re-scripting” of the classic (Aristotelian) tragical emotions of fear and pity, fear being relativized and recontextualized in relation to the superior fear of God, and pity reframed as empathetic mercy. Christian moralists, moreover, expanded the repertoire of “tragical” emotions beyond fear and pity, especially by encouraging a whole gamut of emotions of grief (lamentation, compunction, etc.) that were pivotal in Christian response to the tragic realities of sin, suffering, loss, and death.

Abstract:
There are a small number of legacy, orphan waste, PCM (Plutonium Contaminated Material) drums at Sellafield Site containing calcium metal potentially contaminated by plutonium (Pu), some of which may be in the form of plutonium fluoride (PuF4). These drums were measured on a TRU-D® PCM Drum Monitor to give a Nuclear Safety value for the Pu mass based on Neutron Coincidence Counting (NCC) and the Pu isotopic composition measured for each drum using a germanium detector based High Resolution Gamma Spectrometry system. In some circumstances the presence of Pu in the form of PuF4 can cause a significant overestimate of the measured Pu mass. This is as a result of alphas emitted by the spontaneous decay of Pu isotopes interacting with light elements such as fluorine, resulting in the emission of “random” (alpha, n) neutrons. The potential overestimate may be very large for total neutron counting based systems if the presence of PuF4 is not accounted for in the system calibration. However, significant quantities of PuF4 may also result in overestimates for NCC systems due to potentially large statistical uncertainties in the measurement results caused by accidental coincidences involving the random (alpha, n) neutrons. Therefore in some circumstances, less pessimistic measurements may be obtained from the total neutron count, corrected using the measured “PuF4 ratio”. Standard TRU-D® Drum Monitor measurements of the calcium containing drums were carried out by plant operators. Relevant data was then downloaded from the plant instrument allowing additional off-line techniques to be applied to the high resolution gamma spectra associated with each drum. These spectra are routinely generated as part of the standard TRU-D® PCM Drum Monitor measurement. This analysis was based on the patented PuF4 analysis technique developed by VT Nuclear Services personnel to determine the mass ratio of Pu in the form of PuF4 to total Pu mass using the PuF4 reaction gammas and standard Pu gammas observed in the gamma spectrum. This additional, off-line analysis reduces the potential overestimate in the Pu Nuclear Safety Mass associated with each drum aiding the repackaging of the legacy material into Bull Pit cans. Following this, similar measurements and off-line analysis was carried out for the filled Bull Pit cans using a TRU-D® PCM Piece Monitor set up and commissioned specifically for this task. The further analysis results allowed the Bull Pit cans to be efficiently and cost effectively packed in 200 litre drums. The resulting new 200 litre drums were then measured using a standard, routinely operated TRU-D® PCM Drum Monitor for final sentencing (again taking into account off-line PuF4 analysis) to allow safe and secure storage. This paper describes the work carried out and the additional off-line PuF4 analysis techniques and how they have been applied within the exacting demands of Nuclear Safety in support of legacy material treatment and ultimate safe storage.

Abstract:
The Southern Storage Area at UKAEA’s Harwell site was used from the late 1940’s through until the late 1980’s for the storage, packaging and disposal of various radioactive and chemical wastes. These included beryllium-contaminated wastes arising primarily from the decommissioning of redundant beryllium fabrication facilities. The latter were buried in five unlined, shallow trenches, each being ∼40–50 m long by 6 m wide and 3–4 m deep. An environmental assessment identified three feasible options for the future of these “Beryllium” Pits. These were full excavation with removal of their contents and surroundings, capping and long-term care and maintenance. These options were studied more extensively to select the best practicable environmental option (BPEO), which was excavation. This paper describes in detail the characterisation and remediation approaches used in identifying, planning and successfully implementing that option. It also compares the actual waste arisings in nature, form and quantities with the expectations from the characterisation investigations. At the project commencement limited information existed from records and past trial pitting on the form and contents of the pits. Thus much more extensive characterisation was necessary to determine their dimensions, identify waste types, volumes and disposal routes and quantify potential hazards for any excavations. The characterisation programme involved planning, setting up a site infrastructure, site clearance, non-intrusive surveying and intrusive characterisation by coring. The pit areas and their immediate surroundings were monitored for radiological contamination, followed by geophysical surveys using magnetometry and ground penetrating radar. Primary and secondary containment systems were then constructed over the pits before coring, sampling and analysis on a predefined grid. There was significant beryllium contamination in all pits with some limited contamination by heavy metals, including mercury, and radionuclides. There were also trace levels of volatile organic solvents. These data provided the basis for planning the remediation. The remediation was successfully undertaken to achieve as a minimum a set of remediation targets for residual chemical and radioactive contamination. These targets were determined from site-specific risk assessments, best practice and waste limits. Each pit was remediated within a sealed and ventilated primary containment inside a secondary weatherproof containment building. A horizontal mining approach was adopted to pit excavation with a small excavator initially placed in a launch pit constructed immediately outside the pit. The excavator worked along the pit removing thin layers of waste from an inclined face ahead of it. The waste was placed into bags on trolleys on rails. It was removed via a posting port. After removal of all of the contents and hazardous materials, the containment was removed. Any further excavation required to meet the remediation targets was undertaken in bulk in the open. After verification sampling the remediation was completed by inserting a low permeability barrier of clay and a bentonite geotextile into the base of the pit and backfilling with compacted clean soil. The remediation was completed with successful achievement of all remediation criteria and minimal impacts on the operators, public and environment.

Abstract:
Corrosion pits with a conical shape are typically observed in hold frames in way of cargo holds of bulk carriers which carry coal and iron ore. The ratio of the diameter to the depth of the typical corrosion pits is in the range between 8–1 and 10–1 and its diameter might become up to 50mm. The evaluation of residual strength of members with large uneven pitting corrosion is difficult compared with that of members with general corrosion. Therefore, it is of crucial importance to develop a method for the evaluation of residual strength of pitted members. The purpose of the present study is to investigate the effect of pitting corrosion on the ultimate strength of steel plates under various loading conditions and explore a method for the evaluation of residual thickness of pitted plates. In the present study, a series of non-linear FE-analyses has been conducted with steel plates with a variety of random pit distributions under various loading conditions such as uni-axial compression, bi-axial compression, shear and combination of these. In these analyses, random pit distributions were calculated by the previously developed corrosion model. It has been shown that equivalent thickness loss, which is defined as thickness loss of uniformly corroded plates with the same ultimate strength as the randomly pitted plates, is smaller than or equal to 1.25 times the average thickness loss. It has been also revealed that the equivalent thickness loss for the ultimate strength under the above-mentioned loading conditions is smaller than average thickness loss at the minimum cross section, where the average thickness loss at the minimum cross section almost corresponds to the equivalent thickness loss for the tensile strength. Based on these findings, a method for the estimation of equivalent thickness loss of pitted plates has been discussed using the thickness diminution-DOP relationship, where DOP (Degree of Pitting Intensity) is defined as the ratio of the pitted surface area to the total surface area.

Abstract:
Abstract Particle Image Velocimetry (PIV) was used to measure the flow field of staggered square pin-fin array in a wide rectangle channel (AR = 4). The experiment was conducted at two Reynolds number, 10000 and 20000, based on the hydraulic diameter and bulk velocity of the channel. The distribution of flow field properties was compared with that of Nu to analysis the key flow physics driving heat transfer enhancement in channel with square pin fin. The Nusselt number was achieved through temperature measurement using thermochromic liquid crystal in the same geometry setup. Results were compared with those for circular pin fin to study the effect of geometry on flow physics driving heat transfer enhancement. It was found that the wake length of square pin fin is longer than that of circular pin fin, which indicated flow around square pin fin requires longer distance to develop. Compared to circular pin fin, small scale disturbances in the shear layer of square pin fin show its contribution to local end wall heat transfer enhancement. Large motions benefit end wall heat transfer more effectively at lower Re. Small scale unsteadiness contributes more to heat transfer augment as flow develops or Reynolds number increases while large scale motions get weaker.

Abstract:
Temperature profiles in PET (Polyethylene Terephtalate), PBT (Polybutylene Terephtalate), and PS (Polystyrene) films created due to excimer laser irradiation were estimated analytically from the model of semi-infinite heat flux and numerically from the model based on 1-D heat equation. For the analytical estimation of temperature profile, we initially assumed that all of the irradiated excimer laser energy was confined in surface, and the energy was considered as a constant heat flux during the laser irradiation period. Calculation results showed that this assumption is somewhat inadequate for polymer materials especially for the polymers with low UV absorption coefficients, because we could not exclude the absorption of excimer laser energy in bulk. In order to reduce the error from this assumption, temperature profiles were estimated from numerical solution, which included a heat generating function representing absorption of excimer laser beam in polymer. Temperature measurement results showed a good agreement with this calculation, but only when ablation was not significant (i.e., for PS).

Abstract:
Abstract The velocity field in a wide rectangular channel (AR = 4) with staggered circular pin fin array was measured using Particle Image Velocimetry (PIV). The cylinder pin fin has a diameter of 8 mm and height to diameter ratio (H/D) of 3. The streamwise pitch (X/D) and spanwise pitch (S/D) of pin fins are 4.5 and 2 respectively. The experiment was conducted at two Reynolds number, 10000 and 20000, based on the hydraulic diameter and bulk velocity of the channel. The mean velocity, first-order statistics of velocity fluctuation and turbulent kinetic energy components in the measured plane are given. Results show, the distribution of the cross-stream velocity fluctuation (Vrms), other than second-order statistics, has a similar pattern as that of the local Nusselt number on the end wall between pin fin rows while the flow is in developing. The Nusselt number was achieved through temperature measurement using thermochromic liquid crystal in the same geometry setup. Therefore, compared to second-order statistics, the cross-stream velocity fluctuation might be a simple but crucial flow quantity for heat transfer enhancement using pin fins in the developing region. The shedding of large vortices from circular pin fins is believed to be the primary flow structure inducing the cross-stream velocity fluctuation. Study on pin fins with various geometries is required before further conclusion drawn.

Full text
Abstract:
The following paper outlines a methodology for accurately predicting the burst of a centrifugal rotor, for the purpose of certifying the tri-hub containment capability of an Auxiliary Power Unit gas turbine engine. The tri hub burst is achieved by introducing three equally spaced slots into a centrifugal rotor. Using 2D and 3D finite element analysis, the slot geometry was optimized to ensure burst of the centrifugal rotor at the desired speed, through spin pit testing, and to account for thermal and centrifugal growth for operation in an engine with proper tip clearances. In order to validate the versatility of this methodology, two centrifugal rotor geometries with different material properties (Ti6Al4V and Ti6Al2Sn4Zr6Mo) and operating conditions were analyzed. The analytical predictions were confirmed with isothermal spit pit tests using temperatures that approximate the bulk average temperature in the high stressed bore for an un-slotted centrifugal rotor. The results of spin pit tests were found to be within 0.4% of predicted values. Burst tests were subsequently conducted on a gas generator rig and a full engine test, where results were found to be within 2% of predicted values.
