An Investigation For Optimal Tool Kinematics In Powder Compaction Cycle To Minimize Density Gradient In Green Powder Compacts
Authors: Kostiv Orest
Published: June 2021

The major disadvantage of powder metallurgy (PM) is the density variation throughout the powder compact. During the compaction process, due to the existence of friction at powdertool interfaces, the contact surfaces experience a non-uniform stress distribution having to do with a variable friction coefficient and tool kinematics, consequently resulting in density gradient throughout the green powder compact. This represents a serious problem in terms of reliability and performance as it may contribute to a crack-defect generation during the compaction and ejection cycle, and more importantly a non-uniform powder compact shrinkage during the sintering process. The geometrical distortion caused by non-uniform shrinkage may require secondary operations, thus, compromising the competiveness of PM technology. Simulation analyses, consisting of two parts, were conducted to study and suppress the causes of density variation. First, simulation analyses were conducted using a newly proposed friction-assisted compaction technique for compaction of cylindrical parts. Second study extended to a more complex geometry, consisting of a multi-stepped part, which indirectly used friction-assisted compaction by varying the tool kinematics of the press system. The overall focus of both studies was to establish optimal tool kinematics in powder compaction cycle to minimize density gradient in both cylindrical and multi-stepped green powder compacts. Consequently, optimal tool kinematics were determined producing the least variation in density throughout the corresponding powder compacts. 
Modelling the Safety Performance of Roadways for Specific Collision Types
Authors: Chiu Tony
Published: June 2021

Safety performance functions (SPFs) are rarely developed for specific accident types because this can be very lengthy especially when relevant data are unavailable. Because of this constraint, a factor is applied along with the SPF for all accident types to estimate the safety for specific accidents types. This factor is the proportion of the individual collision type in the entire population of all accidents. However, there is no reason to believe that this factor is a constant which is independent of Annual Average Daily Traffic (AADT). Accordingly, a constant factor and the proportion model are applied to the SPF for all accident types combined to estimate the SPF for specific accident types on both rural road segments and Two-Way Stop-Controlled (TWSC) intersections. The validity of these factors are tested using the state-of-the-art network screening approaches. Furthermore, a detailed investigation on Property Damaage Only (PDO) estimates is carried out on certain aspects of safety performance functions, using negative binomial regression. PDO estimates are then evaluated based on three different approaches.
Modelling the advanced oxidation of the pharmaceutical compound metronidazole in single- and multi-lamp tubular photoreactors
Authors: Johnson Melody Blythe
Published: June 2021

A model was developed to predict the removal of metronidazole utilizing the UV/H₂O₂ AOP. The rate constant for the reaction between metronidazole and the hydroxyl radical was determined ... The model was able to predict an optimal initial H₂O₂ dose, and the inhibitory effects of high H₂O₂ doses and bicarbonate ions in the aqueous solution. Simulations were run for three reactors, at various influent H₂O₂ doses and reactor radii ... 4.9% to 13% removal was predicted for the single-lamp photoreactors, while 14% to 41% was predicted for the multi-lamp photoreactor. Selection of a reactor radius for maximum metronidazole removal varied with influent H₂O₂ concentration. The lowest operational cost of $0.05 per mmol removed was projected for the multi-lamp photoreactor. Operationlly, it was cost effective to utilize higher UV lamp output (36W), while keeping influent H₂O₂ concentration low (25mg/L).
A Numerical Study Of Micro-Jet Impingement Cooling Inside A High Pressure Turbine Vane
Authors: De Paz Marcel L.
Published: June 2021

A thorough numerical analysis of micro-impingement cooling for application in high pressure turbine vanes is presented. The fundamental flow of an axisymmetric jet is first modeled and studied to ascertain the validity of the results. Subsequent, a fully three dimensional curved vane is modeled with an in-line impinging array of jet diamters 0.5mm. The analysis reveals that spent air collects with increasing streamwise distance from the leading edge, thereby increasing jet exit velocities across the array. For all cases studied, an increase in jet to target spacing increased the overall Reynolds number of the array, but decreased the average heat transfer rate. Micro diameters of 0.25mm were subsequently studied for full vane geometry. For a given mass flow per unit of heated area, the micro-jets considerably increased the average heat transfer by 63%. Similar enhancements were obtained at a fixed pressure drop percentage, and for a desired average heat transfer.

Between Art And Photojournalism :An Examination Of Henri Cartier-Bresson's The People Of Moscow
Authors: Walker-Lečić Kova
Published: June 2021

Henri Cartier-Bresson's (French, 1908-2004) career spanned more than fifty years during which he was involved with the surrealist movement, produced work for various picture magazines, helped found Magnum Photos Agency and published numerous photobooks. While his body of work is often discussed in terms of either fine art photography or photojournalism, prior to 1950s these elements tended to be isolated to separate venues. This thesis is concerned with Henri Cartier-Bresson's 1955 book The People of Moscow, a photographic survey of the Soviet people. It considers the significance of this book as a venue that combined the two aspects of Cartier-Bresson's photography, the formal aesthetics and the documentary content and thereby marked a turning point in his career. The essay describes and analyzes the elements of the book's design, such as the layout, sequencing and use of text by comparing them to the earlier Cartier-Bresson monographs, as well as to the use of the photographs from the book in Life and Paris Match.
A study of hot tearing during solidification of B206 aluminum alloy
Authors: D’Elia Francesco
Published: June 2021

Aluminum-copper (Al-Cu) alloy B206 is a high strength and ductile alloy showing promise for use in automotive suspension components. Incorporation of lightweight B206 alloy in automotive suspension components may significantly reduce overall vehicle weight and increase the vehicle’s fuel efficiency. However, one of the major factors inhibiting the use of B206 is its high susceptibility to hot tearing during casting. Hot tearing is a complex phenomenon attributed to alloy solidification, microstructure and stress/strain development within a casting. Numerous methods (e.g. preheating of mold, grain refinement, elimination of sharp corners in a component) help to reduce the occurrence of hot tears in castings, but the underlying mechanisms responsible for hot tearing remain ambiguous. This research aims to advance the understanding of the mechanisms responsible for hot tearing in B206 Al alloy.

In this research, the conditions associated with the formation of hot tears in B206 were investigated via ex situ and in situ methods. Titanium was added in three levels (i.e. unrefined, 0.02 and 0.05 wt%) to investigate the effect of grain refinement on hot tearing. Ex situ neutron diffraction strain mapping was carried out on the three B206 castings to determine casting strain and stress. Further, in situ techniques were used to establish the onset temperature and solid
fraction of hot tearing in B206 and to improve the understanding of microstructure development in B206.

The results indicate that titanium additions had a significant impact on the hot tearing susceptibility of B206, by effectively reducing grain size and transforming grain morphology from coarse dendrites to fine globular grains. Further, thermal analysis suggested that grain refinement delayed the onset of dendrite coherency in B206 and therefore enhanced the duration of bulk liquid metal feeding for the refined casting conditions. As a result, the interactive effects of such factors resulted in a more uniform distribution of strain, and subsequent higher resistance to hot tearing for the grain refined castings. Finally, in situ analysis determined the onset solid fraction of hot tearing in B206 and provided an understanding of the role of microstructure on hot tearing in B206.
Phases of the Moon: A Study of 19th Century Scientific Book Illustrations, Providing a Comprehensive Catalogue for the First Three Editions of James Nasmyth & James Carpenter's The Moon: Considered as a Planet, a World, and a Satellite
Authors: Ramsey Laura Margaret
Published: June 2021

James Hall Nasmyth (1808–1890) was an accomplished engineer and amateur astronomer. The culmination of Nasmyth's drawings from telescopic observation, the advent of photomechanical print processes, and his interest in the causative features of the lunar surface, led to the 1874 publication of The Moon: Considered as a Planet, a World, and a Satellite. This thesis provides a comprehensive catalogue of the lunar illustrations in the first three editions, revealing the aesthetic variations in the illustrative plates due to reproduction and print processes used. These processes include: engraving, photogravure, heliotype, lithograph, chromolithograph, and four different variations of the Woodburytype. The editions are contextualized using scientific photographs as illustrations, through a discussion of astronomy, book production, and Nasmyth's biography. Through an examination of Nasmyth's use of photography and permanent print processes, this thesis argues that his lunar illustrations remain an important scientific contribution.
Parametric study of curved steel I-girder bridges at construction phase.
Authors: Haq lhsan-ul
Published: June 2021

The desire to conform to the existing terrain has largely increased the use of curved bridges for complex interchanges. Bridge curvature produces warping moments (lateral bending moments) in girder flanges under truck loading conditions and even during the construction phase. These warping moments increase girder flexural stresses at construction phase in case of un-shored construction. An extensive parametric study was conducted, using the finite-element analysis software "SAP2000", to examine the key parameters affecting warping stresses in curved girder bridges under construction loads. A strengthening technique "torsion box" at the girder supports was proposed and examined with respect to girder warping, flexural stresses and support reactions. The key parameters considered in this study included number of girders, girder spacing, number of cross bracing intervals, degree of curvature and girder span length. Based on this study empirical expressions for moment and shear distribution factors for the curved girder were developed.
Local calibration of MEPDG rutting model for Ontario’s Superpave pavements
Authors: Gautam Gyan Prasad
Published: June 2021

The rutting models in the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) have been calibrated to Ontario’s conditions for flexible pavements of Marshall mixes, and have yet to be calibrated for the Superpave materials. This study differs from previous studies in several counts: First, the local calibration database included both Superpave and Marshall mixes. Second, two of the five local calibration parameters (the temperature and traffic exponents) were pre-fixed based on a secondary study of the NCHRP 719 report. Third, both cross-sectional and longitudinal calibrations were performed and compared. It was concluded that the Superpave and Marshall mix pavements should be separately treated in the local calibration and that the cross-sectional and longitudinal calibrations behaved drastically differently in terms of residual errors. A set of local calibration parameters were recommended for future pavement design. It was recommended that trench investigations be done to further validate the results from the study.
Investigation of pullout strength of pre-installed glass fibre reinforced polymer bars in high-performance concrete
Authors: Lu Jennifer
Published: June 2021

Fibre reinforced polymer (FRP) bars are rapidly becoming an alternative to conventional steel reinforcing bars in bridge construction. This research investigated the bond behaviour of glass fiber reinforced polymer (GFRP) bars embedded in high-­‐performance concrete (HPC). Sand-­‐coated and ribbed-­‐surface GFRP bars of 16 and 20 mm diameters were considered in this study. Concrete blocks were cast with embedded GFPR bars to conducted pullout tests to examine the effect of varying parameters on their pullout and bond strengths, namely: embedment length, bar diameter, surface treatment, and concrete cover. In addition, bond characteristic were analyzed between straight and head-­‐ended sand-­‐coated GFRP bars. The experimental results were used to evaluate the development lengths specified in design codes. It was determined that the development lengths for straight GFRP bars provided by the codes are conservative. Also, the development length for head-­‐end bar is shorter than that for similar bar with straight end.

Authors: Samani Shirin Ghatreh
Published: June 2021

This research presents the results of experimental investigation conducted on 1/4th scale link slabs subjected to monotonic and fatigue loading incorporating different ECC mixtures and self-consolidating concrete (SCC). The structural performance for the link slabs are evaluated based on the load-deformation/moment-rotation responses, strain developments, cracking patterns, ductility index and energy absorption capacity. Test results of a 1/6th scale full bridge with ECC link slab tested under monotonic loading up to service stage is also described. The experimental link slab moment resistance and its length are compared with those obtained from theoretical and design specifications. The ECC link slabs demonstrated superior performance exhibiting high residual strength and energy absorbing capacity and prolonged life (associated with enduring large number of fatigue cycles) compared to their SCC even though subjected to higher fatigue stress levels. This research confirmed the viability of ECC link slab to construct joint-free bridges satisfying serviceability and design specifications.
Structural behaviour of composite slab with high performance concretes
Authors: Mengistu Haile
Published: June 2021

Composite slabs with profiled steel deck and concrete toping have gained wide acceptance as they lead to faster, lighter and economical construction. Extensive research works have been conducted on the behaviour of composite slabs to study their structural behavior and steel-concrete interface shear bond resistance which primarily governs the failure. However, the use of emerging highly durable engineered cementitous composite (ECC) in composite slab is new and no research has been conducted yet. High strain hardening and intrinsic crack width characteristics of ECC can significantly improve structural performance of composite slabs through enhancing ductility, energy absorbing capacity and steel-concrete shear bond. In this study, experimental investigations are conducted to evaluate the shear bond characteristics of composite slabs made with ECC and conventional self-consolidating concrete (SCC) using Code based m-k method. Twelve slab specimens having variable shear span and two types of profiled steel deck were tested under four point loading. The performance of ECC and SCC composite slabs are compered based on load-deflection response, stress-strain development in concrete and steel, failure modes, energy absorbing capacity and steel-concrete shear bond parameters (m and k) and bond stress.

Ekkorra a gazdaság már kilábalt a kétezres évek végén ránk tört világgazdasági válságból, ugyanakkor konjunkturális haladás indult el. Ezzel szoros összefüggésben a munkaerőpiacon folytatódtak a kedvező fejlemények. A mostani évtized nyitásakor ránk támadt koronavírus okozta egészségügyi világjárvány mélyen érinti a gazdasági-társadalmi viszonyainkat. Elemzésünkben arra vállalkozunk, hogy az  említett aranykor  demográfiai, gazdasági, továbbá munkaerő-piaci főbb tényezőit számba vegyük, annak érdekében, hogy ezen tényezők válság utáni helyzetének, alakulásának látásához egyfajta lehetséges támasztékot, bázist adjunk.  Emellett éppen az egészségügyi járvány, illetve annak hatásai majdani elemzése érdekében, mintegy természetes módon kiemelten foglalkozunk a válság előtti időszak lakossági egészségességi állapotának egyes főbb jellemzőivel.In Hungary, the second part of the latest decade can in some sense called a „golden era”. By this time, the economy had recovered from the world economic crisis burst out in the late 2000s, and conjunctural development started. In close relation to this, favourable improvements appeared on the labour market. The world pandemic caused by Corona virus having attacked us at the opening of this decade is having a deep impact on our socio-economic circumstances. In this analysis, I undertake to consider the main demographic, economic and labour market factors of the mentioned golden era in order to provide a base for the picture of the evolution of these elements after the crisis. In addition, exactly for the sake of the future analyzation of the crisis and its impacts, I highlight the main characteristics of the people’s health conditions before the crisis.

Published: June 2021

A precipitação pluviométrica é uma das variáveis meteorológicas mais relevantes para estudos climáticos. Conhecer sua variabilidade espacial e temporal permite planejar diversas atividades humanas, tanto do ponto de vista econômico quanto social. Tal importância deve-se às consequências que ela pode ocasionar, em excesso ou em falta, causando enchentes, inundações, secas, queda no fornecimento de energia, baixa produção de alimentos, entre outros. Este trabalho teve como objetivo estudar a série histórica de precipitação pluviométrica média mensal da cidade de Lavras/MG a fim de obter um modelo estatístico que permita realizar previsões, para isso utilizou-se 228 observações correspondente ao período de janeiro de 2000 a dezembro de 2018. Para esta análise, foi verificada a existência das componentes tendência e sazonalidade. A metodologia de Box e Jenkins foi utilizada na modelagem dos dados. Foram ajustados alguns modelos utilizando a classe SARIMA, pois a série em estudo apresentou sazonalidade estocástica. A comparação entre os modelos considerados adequados à série foi realizada através do EQM e AIC. O modelo SARIMA (0,0,0) x (0,1,1)12 foi utilizado para fazer previsões de observações futuras. A série de precipitação pluviométrica média mensal da cidade de Lavras/MG apresentou uma componente sazonal com periodicidade de 12 meses. O modelo ajustado obteve um resultado muito bom, pois os intervalos de confiança a 95% contiveram os doze valores reais de precipitação pluviométrica média mensal da cidade de Lavras/MG para o ano de 2019, mesmo diante dos imprevistos e incertezas associadas a fatores climáticos. O modelo em questão pode ser utilizado na tomada de decisões para a realização de planejamentos estratégicos futuros que envolvem questões públicas associadas à cidade de Lavras. Estas previsões também podem ser utilizadas para auxiliar os gestores da usina hidrelétrica do Funil/MG a programar operações e manutenções futuras da vazão de água de forma adequada, pois esta se encontra próxima ao município de Lavras.

A palma (Opuntia e Nopalea) é uma das forrageiras mais importantes do mundo, nativa do México, pertencendo à família Cactaceae, e possui uma alta eficiência no uso da água. No Brasil é cultivada principalmente no Nordeste, onde é considerada estratégica devido as condições climáticas da região. Pesquisas indicam que a adubação orgânica induz um melhor desempenho produtivo da palma forrageira. Neste sentido, o uso de biofertilizante para suprir as necessidades nutricionais das culturas agrícolas, tem sido uma importante ferramenta para os produtores rurais, por se tratar de um insumo orgânico de baixo custo, resultante da fermentação aeróbica de matéria orgânica e água, e que pode influenciar positivamente as propriedades químicas e físicas do solo. Esta revisão de literatura tem por objetivo apresentar alternativas de práticas agrícolas com adubação orgânica como o uso de biofertilizantes em sistemas de cultivo com palma forrageira visando alternativas promissoras com eficiência de cultivo. Conclui-se que o cultivo de palma forrageira com utilização de biofertilizantes alternativos orgânicos, incrementam a produção das plantas, e viabilizar técnicas de baixo custo aos produtores rurais.

O Programa de Educação pelo Trabalho para a Saúde (PET-Saúde) visa reorientar a formação profissional em saúde a partir da inserção de estudantes nos serviços de saúde. Com a pandemia de covid-19 as atividades dos grupos tutoriais precisaram ser repensadas em função do interrompimento das atividades presencias. Este estudo de caso objetivou conhecer o processo de adaptação dos grupos tutorias para o desenvolvimento de atividades no contexto da pandemia de covid-19. Foram entrevistados 32 integrantes de projetos PET-Saúde do estado do Rio de Janeiro. Seis movimentos de adaptação foram identificados: replanejamento das ações, adaptação para o uso das tecnologias digitais, intensificação das atividades intragrupos, constituição de grupos de apoio, apoio às secretarias de saúde, e educação em saúde por meio das mídias sociais. Os movimentos de adaptação são flexíveis a ajustamentos, permitindo que os grupos reflitam e incorporem a complexidade do contexto pandêmico e as necessidades da comunidade no desenvolvimento das ações. As ações desempenhadas, planejadas e estruturadas coletivamente, respeitando-se as limitações e vulnerabilidades dos estudantes, preceptores e tutores, demonstram que é possível apoiar o enfrentamento da pandemia de covid-19, e ensinar e aprender a partir da realidade cotidiana dos serviços de saúde, mesmo não estando na linha de frente.

Face-to-Face Communication in Aphasia: The Influence of Conversation Partner Familiarity on a Collaborative Communication Task

Published: June 2021

Aphasia is language impairment due to acquired brain damage. It affects people’s ability to communicate effectively in everyday life. Little is known about the influence of environmental factors on everyday communication for people with aphasia (PWA). It is generally assumed that for PWA speaking to a familiar person (i.e. with shared experiences and knowledge) is easier than speaking to a stranger (Howard, Swinburn, and Porter). This assumption is in line with existing psycholinguistic theories of common ground (Clark, 1996), but there is little empirical data to support this assumption. The current study investigated whether PWA benefit from conversation partner (CP) familiarity during goal-directed communication, and how this effect compared to a group of neurologically healthy controls (NHC). Sixteen PWA with mild to severe aphasia, sixteen matched NHC, plus self-selected familiar CPs participated. Pairs were videotaped while completing a collaborative communication task. Pairs faced identical Playmobile rooms: the view of the other’s room was blocked. Listeners attempted to replicate the 5-item set-up in the instructor’s room. Roles were swapped for each trial. For the unfamiliar condition, participants were paired with another participant’s CP (PWA were matched with another PWA’s CP based on their aphasia profile). The outcomes were canonical measures of communicative efficiency (i.e. accuracy, time to complete, etc.). Results showed different effects in response to the unfamiliar partner for PWA compared to NHC: In the instructor role, PWA showed faster trial times with the unfamiliar partner, but similar accuracy scores in both conditions. NHC, on the other hand, showed similar trial times across CPs, but higher accuracy scores with the unfamiliar partner. In the listener role, PWA showed a pattern more similar to NHC: equal trial times across conditions, and an improvement in accuracy scores with the unfamiliar partner. Results show that conversation partner familiarity significantly affected communication for PWA dyads on a familiar task, but not for NHC. This research highlights the importance of identifying factors that influence communication for PWA and understanding how this effect varies across aphasia profiles. This knowledge will ultimately inform our assessment and intervention of real-world communication.
Case Report: Metreleptin Treatment in a Patient With a Novel Mutation for Familial Partial Lipodystrophy Type 3, Presenting With Uncontrolled Diabetes and Insulin Resistance

Background

Familial partial lipodystrophy type 3 (FPLD3) is a very rare autosomal dominant genetic disorder which is caused by mutations in the peroxisome proliferator activated receptor gamma (PPARG) gene. It is characterized by a partial loss of adipose tissue leading to subnormal leptin secretion and metabolic complications. Metreleptin, a synthetic analogue of human leptin, is an effective treatment for generalized lipodystrophies, but the evidence for efficacy in patients with FPLD3 is scarce.

Case Presentation

We present a 61-year-old woman, initially misdiagnosed as type 1 diabetes since the age of 29, with severe insulin resistance, who gradually displayed a more generalized form of lipoatrophy and extreme hypertriglyceridemia, hypertension and multiple manifestations of cardiovascular disease. She was found to carry a novel mutation leading to PPARGGlu157Gly variant. After six months of metreleptin treatment, HbA1c decreased from 10 to 7.9% and fasting plasma triglycerides were dramatically reduced from 2.919 mg/dl to 198 mg/dl.

Conclusions

This case highlights the importance of early recognition of FPLD syndromes otherwise frequently observed as difficult-to-classify and manages diabetes cases, in order to prevent cardiovascular complications. Metreleptin may be an effective treatment for FPLD3.
