Stem cells provide various potential applications in regenerative medicine through its ability of self-renewal and differentiation. Among the various stem cells, dental pulp stem cells (DPSCs) have shown encouraging results in their ability to regenerate. Honey has been used in traditional culture as a natural medicine in supporting wound healing. Yet, very few studies on honey were conducted for its potential as a proliferative agent for stem cells. The aim of this study is to evaluate the stability of two Trigona spp. honeys (1 and 2) added in culture media and its proliferative effect on DPSCs. Both honeys were diluted with standard culture medium through dilution process to prepare the concentrations of 0.01%, 0.04%, 0.10% and 0.25%. DPSCs were treated with the diluted honeys for 24 hours. The proliferative activity was determined through the images taken using an inverted microscope for every six hours. In addition, the MTT assay was conducted to determine the cell viability of DPSCs when treated with both honey 1 and 2 at various concentrations. The results showed a stable culture media added with honey for three days and a dose-dependent proliferative effect of both Trigona spp. honey samples on DPSCs. Optimum proliferative effects were observed at 24 hours for both Trigona spp. honey 1 and 2 on DPSCs. The optimum concentration of Trigona spp. honey 1 was from 0.04% to 0.10% and Trigona spp. honey 2 was below 0.01%. It is concluded that Trigona spp. honey has a promising proliferative effect on DPSCs.
Gerrymandering Hypothesis in the Italian Constituencies
Authors: Ratto Trabucco Fabio
Published: June 2019

Gerrymandering is a practice intended to establish a political advantage for a particular party or group by manipulating district boundaries. The term gerrymandering has negative connotations. Two principal tactics are used in gerrymandering: “cracking” (i.e. diluting the voting power of the opposing party’s supporters across many districts) and “packing” (concentrating the opposing party’s voting power in one district to reduce their voting power in other districts). Partisan gerrymandering to increase the power of a political party has been practiced since the beginning of the US. What’s happening in Italy? The paper examines a hypothesis of Italian gerrymandering: the uninominal constituencies of the Genoa’s District where typically progressive voting areas are united with conservative suburbs and municipalities. Last but not least the initiatives against the gerrymandering in American history to understand how to identify and contrast the techniques of gerrymandering.
Restorative pathways after mass environmental victimization
Authors: Varona Gema
Published: June 2019

Departing from the parallelism between large-scale human rights violations and the complex notion of ecocide, some conceptual remarks will be drawn within the realm of green victimology and restorative justice. By questioning the frameworks of victimhood and the irreversibility of ecocide, some conclusions about the meaning of informal practices of memorialization in mass victimization can be discussed. To illustrate these ideas, the Prestige case in Spain will be briefly presented as a case study. Partiendo del paralelismo entre las violaciones de derechos humanos a gran escala y la compleja noción de ecocidio, se realizarán algunas consideraciones conceptuales dentro del campo de la victimología verde y la justicia restaurativa. Al cuestionar los marcos de la victimidad y de la irreversibilidad del ecocidio, se debatirán algunas conclusiones sobre el significado de ciertas prácticas informales de memorialización en procesos de victimización en masa. Para ilustrar estas ideas se recurrirá de forma sucinta, como caso de estudio, a las consecuencias del Prestige en España. Available from: https://doi.org/10.35295/osls.iisl/0000-0000-0000-1044
Environmental resistance in the Anthropocene
Authors: Collins Lynda M.
Published: June 2019

Scientists describe the current “Anthropocene epoch” as one of profound anthropogenic disruptions in the ecosphere that place humanity at an unacceptable risk. This unprecedented ecological moment in human history is rooted in profoundly unsustainable patterns of production and consumption protected by liberal power structures expressed through law. The exigencies of the Anthropocene call us to expand the subjects of resistance to include future generations of humans, plants, non-human animals, ecosystems and “non-living” natural entities (such as water, air and climatic systems). Since these constituencies cannot resist in a socio-political sense, their representation in current socio-political systems will depend upon “an insurrection of subjugated knowledges” (Foucault 1980, p. 81) including Indigenous law, pre-modern holistic traditions of Western legal thought, and emerging theories of ecological law. This article will explore these approaches as possible paths forward in the Anthropocene, employing a comparative law perspective that considers relevant jurisprudence and policy developments from around the globe.
Forms of subjectification
Authors: Finco Matteo
Published: June 2019

Health represents a context where it is possible to observe the relationship between individuals and society, namely which spaces of autonomy are left for the individuals and which social forces are exercised on them. If Critical Theory points out the mechanisms of a neoliberal matrix that makes individuals “subjugate subjects”, Social System Theory allows to investigate how they are “included” in various spheres of society. Integrating these theories, we investigate mechanisms of subjectification on health. Moreover, through the analysis of the recent Italian law on advance directives and living will, we question if the claims of self-determination expressed by individuals could represent a form of “resistance” against neoliberal policies. Through a theoretical reflection and an analysis of the background and the juridical consequences of the law n. 219/2017, we conclude that the individual autonomy could be exercised together with responsibility towards others, balancing individual needs and claims with social solidarity.

CLAUDIA ROQUETTE-PINTO: “É impossível verbalizar o que realmente interessa”.
Authors: Bastos Dau , Coelho Eduardo , Magdiel Lucas
Published: June 2019

Claudia Roquette-Pinto integra o reduzido rol dos artistas contemporâneos a manter a metafísica como horizonte. Em vez de se enredar na teologia, porém, encara a impossibilidade de dar conta do inefável como estímulo para aprofundar a lida com a linguagem, instada a conectar o etéreo e o corpóreo, a especulação filosófica e a carga cotidiana.Afeita ao diálogo com escritores e poetas, Claudia incorpora trechos alheios a seu próprio texto, por vezes criando poemas que impressionam pela singularidade com que harmonizam múltiplas vozes. Igual abertura demonstra em relação a outras artes, que aproveita como motivo ou inspiração, ao mesmo tempo que as pratica com a intensidade com que faz poesia.Sua condição de criadora multimídia talvez explique um charmoso desprendimento que a leva a cogitar de um dia parar de escrever. Tranquiliza-nos o fato de seus livros se mostrarem cada vez mais trabalhados e serem acolhidos com crescente entusiasmo pela crítica.Sobre eles a poeta falou em sua casa, onde Dau Bastos, Eduardo Coelho e Lucas Magdiel estiveram numa noite especialmente chuvosa, propícia ao intimismo das conversas mobilizadoras.
Escrevendo pinturas e pintando palavras: a interarte poética de Raquel Naveira
Authors: Santana Patricia Maria Dos Santos
Published: June 2019

Os textos de Raquel Naveira não se fazem sobre uma folha em branco. O olhar para duas artes que se cruzam e se predispõem ao diálogo exige reflexão. Na caligrafia da poeta, encontramos resquícios de quadros dos quais foi leitora, fazendo questão de resgatar essa leitura sensível no traço de sua escrita. Muitas vezes, vozes do passado e do presente se fundem. O diálogo intertextual manifesta a importância do visual e a importância da palavra. Naveira se prevalece do encontro entre as artes para executar uma poesia que almeja integrar concretude e sentimento, algo feito e algo refeito, o mostrado e o sentido. Relaciona a busca de uma linguagem que não reconsiderasse o passado, mas o reinventasse. Ao observar uma arte visual e demonstrar no papel o que sentiu e viu, Naveira se torna ponte entre a arte experimentada e o mundo e, também, com o receptor, que pode ir além de uma leitura superficial do todo. Naveira é leitora dos quadros e também uma artista inspirada pela sua força. Seu olhar específico para as artes é uma das fontes da grande força de sua produção artística.
Um romance vintage. Glória, de Victor Heringer
Authors: Saramago Victoria
Published: June 2019

Glória é um romance de muitas glórias, seja na polissemia da palavra detidamente explorada ao longo da narrativa, seja no último feito alcançado pelo autor, ao ficar em segundo lugar no Prêmio Jabuti por um primeiro romance, publicado aos vinte e poucos anos, que concorria com nomes já bem estabelecidos na cena literária atual. Se a boa surpresa a princípio inibe críticas negativas, a prosa trabalhada de Victor Heringer, aliada à cuidadosa arquitetura do enredo, tampouco as encorajam. Dado a temáticas contemporâneas, referências à obra machadiana e múltiplas tramas, o livro pede reflexão sobre a linguagem e uma abordagem pelo viés da irionia.
LEONARDO MARTINELLI: “Nem tudo são temas e metros na composição do poema”.
Authors: Gomes Alessandra , Bastos Dau , Andrade Pedro , Barreto Rosana
Published: June 2019

Respondendo a uma verdadeira bateria de perguntas, Leonardo demonstrou uma consistência que, juntamente com a beleza de seus textos, deixava entrever um futuro promissor. Infelizmente, alguns anos depois faleceu -- o que torna ainda mais significativa a publicação desta entrevista. Considerado parte de uma geração nomeada fluidamente como “Pós-pós”, o saudoso poeta não se via à frente de nada, apenas escaldado o suficiente para encarar tradição e contemporaneidade como complementares. Postura semelhante adotava na relação com as demais artes, em abertura cuja fecundidade se percebe em sua poesia.
A ficção como artifício em Diário de um fescenino, de Rubem Fonseca
Authors: Camargo Flávio Pereira
Published: June 2019

Diário de um fescenino é um romance em forma de diário no qual o personagem-escritor, que também exerce a função de narrador, se sente totalmente à vontade para se mostrar ao leitor. Assim, inscreve-se na tradição do romance metaficcional, do livro dentro do livro. Nele, há uma reflexão sobre a própria escrita por um personagem-escritor que, além de se expor, revela os elementos caros à narrativa de Rubem Fonseca: o grotesco, o sexo, os crimes e suspenses, que se mesclam às reflexões sobre os procedimentos de construção e elaboração da narrativa, exigindo a cooperação ativa do receptor em seu percurso de leitura.
PEDRO MEIRA MONTEIRO: “O interesse pelo Brasil se acendeu, e não acho que vá se apagar tão facilmente”.
Authors: Bastos Dau
Published: June 2019

Pedro Meira Monteiro se formou pela Unicamp e pela Universidade de Versalhes. Professor da Universidade de Princeton desde 2002, vive dando palestras pelo mundo e vem ao Brasil com regularidade. Sua atuação multifacetada e sempre voltada para os trópicos inclui a edição do periódico ellipsis e, em parceria com colegas de sua própria instituição e da USP, a coordenação da Rede Global Colaborativa “Raça e Cidadania nas Américas” (RACA).Dedicado à literatura e à história cultural, o dublê de docente e ensaísta tem uma vasta lista de textos publicados, entre artigos e livros de sua autoria, além de coletâneas que organizou sozinho ou em parceria. Em meio a vários autores que pesquisou com afinco, destaca-se Sérgio Buarque de Holanda.Nesta entrevista, analisa diferentes interfaces do Brasil com o exterior, com ênfase na literatura. A argúcia e o criticismo são duas características a perpassarem suas respostas, em movimento que as imuniza contra qualquer traço de ufanismo, tanto quanto respalda sua aposta de que, apesar dos reveses, nosso país entrou definitivamente na pauta do planeta.
Dados cinéticos. “Deuses”, de Augusto de Campos
Authors: Wiese Maíra Borges
Published: June 2019

Acreditamos que cabe aos deuses projetar nossos destinos. No poema cinético de Augusto de Campos, entretanto, eles surgem de maneira incomum. Parece haver um erro, uma contradição na associação das palavras “deuses” e “dados”. Deuses não podem doar “acaso”.  Mas, enfim, se os deuses nos doam dados, oferecem possibilidades, escolha, livre-arbítrio; e os deuses de Augusto parecem não pedir nada em troca (“dados doados doem”). O que faz, então, os deuses doerem? Não estão felizes com as escolhas feitas pelos homens? Há muitas razões para dizermos que não: não estão felizes.
A violência oblíqua em “Onze de Maio”, de Rubem Fonseca
Authors: Manzoni Filipe
Published: June 2019

O escritor mineiro Rubem Fonseca é conhecido pela destreza com que ficcionaliza a brutalidade urbana. Em vista da saturação do enfoque desse traço de sua obra, este ensaio privilegia o conto “Onze de Maio”, que é menos eletrizante, não comporta cena de sangue e tem a violência dissimulada pela coerção. Ambientado num hospício, o enredo dá conta de um desvario que, mais se esforça por virar motim, mais deixa ver seu próprio quixotismo, tanto quanto a implacabilidade da norma.
De palavras e silêncios: Belém no centro-periferia da poética de Vasco Cavalcante
Authors: Nunes Paulo , Costa Vânia Torres
Published: June 2019

Esta análise partilha com a poesia a soltura da linguagem e o cultivo da mais ampla ideia de horizonte. Em seu centro, encontra-se o exame minucioso do volume em versos Sob silêncio, do paraense Vasco Cavalcante (2015). Em suas bordas, vemos uma Belém pródiga em iniciativas literárias, a exemplo do grupo Fundo de Gaveta (que o poeta integrou na década de oitenta) e da plaquete Cultura Pará: 30 poetas, 30 poemas (que mostra a capital do Pará tomada pela efervescência literária).
Sem-vergonhices, descaramentos e safadezas na obra de Marcelino Freire
Authors: Maia Helder Thiago
Published: June 2019

Marcelino Freire é apresentado como alguém que escreve para oferecer alguma visibilidade aos marginalizados e perturbar os códigos com que as diferentes injustiças se perpetuam. Para comprovar a pertinência de tal hipótese, este ensaio se atém a três livros do autor, dos quais analisa seis contos e um poema. Assim, traz à tona uma versatilidade estilística que faz pensar que a abertura do pernambucano às mais diferentes alteridades enriquece sobremaneira sua criação.
Sustentando-se como um meio de vida: ir com a poesia de Annita Costa Malufe
Authors: Magalhães Danielle
Published: June 2019

Este ensaio salienta o caráter precário e fugidio de certos temas da poesia de Annita Costa Malufe para se permitir um tateio de que resulta um texto perpassado pela imanência, no qual o imponderável alforria e areja. Em pauta, entram poemas de quatro livros da autora paulistana, esmiuçados por meio de imersões em versos dos quais a analista parece emergir ainda mais dada ao risco. A estimular a aposta no potencial da deriva e, ao mesmo tempo, oferecer algum substrato, encontra-se uma bibliografia marcadamente filosófica, em que se distinguem desde Karl Marx até Gilles Deleuze.
SILVIANO SANTIAGO: “Me interessa quebrar um pouco certo paradigma estabelecido pela universidade, de abordar apenas o texto”.
Authors: Neto Godofredo De Oliveira
Published: June 2019

Esta entrevista nasceu de um encontro vibrante de Silviano Santiago com os estudantes e professores da Faculdade de Letras da UFRJ. Convidado a falar sobre seus dois últimos livros -- o romance Machado e o ensaio Genealogia da ferocidade -- ensaio sobre Grande sertão: veredas, de Guimarães Rosa --, o escritor e professor dilatou o foco para tratar de vários títulos de sua vasta obra e abordar questões cruciais dos estudos literários.Em sua fala, sublinhou o fato de estar com oitenta anos de idade para se dizer numa fase da vida em que pode reduzir a carga de leitura e ousar desfazer até mesmo de caminhos trilhados durante sua formação. Não por acaso, há bastante tempo seu ensaio e sua ficção embaralham os gêneros e põem abaixo barreiras colocadas para sua geração, a exemplo da empobrecedora ideia de rebaixar a biografia, o contexto e qualquer outra fonte de elementos ditos extraliterários, para limitar a atenção ao texto em si.
Paris em São João de Meriti: do fake ao absurdo. Leonardo contra Paris, de Márcio-André Haz
Authors: Ribeiro Felipe Fernandes
Published: June 2019

Márcio-André Haz entrega o protagonismo de Leonardo contra Paris a um escritor suburbano que, ao perder a namorada que lhe dava guarida no abastado bairro do Leblon, inventa uma viagem a Paris, onde supostamente lecionaria na Sorbonne. Manifestada a mentira, nada mais fácil que sustentá-la nessa fábrica de fanfarrice chamada rede social: fotomontagens e outros recursos de edição fingem tão bem o sucesso na França que despertam enxurradas de curtidas. Em sua resenha, Felipe Fernandes Ribeiro destaca que o engodo se espessa ao se apresentar como marca do próprio mundo literário, igualmente movido pela farsa interesseira.
Poesia punk pônei, corpo, colagem e subversão. Furiosa, de Ana Rüsche

A antologia Furiosa se faz de quatro livros de Ana Rüsche: os já publicados, Rasgada (2005), Sarabanda (2007), Nós que adoramos um documentário (2010); e o inédito, Inverno num país tropical (2015). Esta resenha percorre a obra pelas perspectivas do corpo e da colagem para mostrar  que a autora tem uma predileção por borrar limites e subverter padrões. O termo punk pônei é uma alusão ao poema “lugar-comum 36: maquiagem” e se relaciona à contundência e à assertividade de suas construções poéticas.
Market Returns to Education in Pakistan, Corrected for Endogeneity Bias
Authors: Haider Bhatti Sajjad , Aslam Muhammad , Bourdon Jean
Published: June 2019

This paper estimates the Mincer wage model for Pakistan’s labor market, using a relatively recent dataset and new independent variables. We employ instrumental variables and two-stage least squares to address the problem of the endogeneity of education. Our results show that the returns to education are biased downward due to endogeneity, with significant wage gaps emerging among different regions, between genders and between urban and rural job markets. The study’s choice of instruments has conceptual as well as empirical grounds. Our findings establish that the wage determination process is different for males and females across provincial labor markets.
Source-All-Around Tunnel Field-Effect Transistor (SAA-TFET): Proposal and Design
Authors: Shaker Ahmed , Maged Ahmed , Elshorbagy Ali , AbouElainain Abdallh , Elsabbagh Mona
Published: June 2019

In this paper, a new source-all-around tunnel field-effect transistor (SAA-TFET) is proposed and investigated by using TCAD simulation. The tunneling junction in the SAA-TFET is divided laterally and vertically with respect to the channel direction which provides a relatively large tunneling junction area. An n+ pocket design is also introduced around the source to enhance tunneling rates and improve the device characteristics. In addition, the gate and n+ pocket region also overlap in the vertical and the lateral directions resulting in an enhanced electric field and, in turn, the ON-state current of the SAA-TFET is highly increased compared with the conventional TFET. Promising results in terms of DC (I

We present a mid-infrared (IR) sample study of nearby ultraluminous X-ray sources (ULXs) using multiepoch observations with the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. Spitzer/IRAC observations taken after 2014 were obtained as part of the Spitzer Infrared Intensive Transients Survey. Our sample includes 96 ULXs located within 10 Mpc. Of the 96 ULXs, 12 have candidate counterparts consistent with absolute mid-IR magnitudes of supergiants, and 16 counterparts exceeded the mid-IR brightness of single supergiants and are thus more consistent with star clusters or non-ULX background active galactic nuclei. The supergiant candidate counterparts exhibit a bimodal color distribution in a Spitzer/IRAC color–magnitude diagram, where “red” and “‘blue” ULXs fall in IRAC colors [3.6] – [4.5] ∼ 0.7 and [3.6] – [4.5] ∼ 0.0, respectively. The mid-IR colors and absolute magnitudes of four “red” and five “blue” ULXs are consistent with those of supergiant B[e] (sgB[e]) and red supergiant (RSG) stars, respectively. Although “blue,” RSG-like mid-IR ULX counterparts likely host RSG mass donors; we propose that “red” counterparts are ULXs exhibiting the “B[e] phenomenon” rather than hosts of sgB[e] mass donors. We show that the mid-IR excess from the “red” ULXs is likely due to thermal emission from circumstellar or circumbinary dust. Using dust as a probe for total mass, we estimate mass-loss rates of

Published: June 2019

The main carrier of sulfur in dense clouds, where it is depleted from the gas phase, remains a mystery. Shock waves in young molecular outflows disrupt the ice mantles and allow us to directly probe the material that is ejected into the gas phase. A comprehensive study of sulfur-bearing species toward L1157-B1, a shocked region along a protostellar outflow, has been carried out as part of the IRAM-30 m large program ASAI. The data set contains over 100 lines of CCS, H2CS, OCS, SO, SO2, and isotopologues. The results of these observations are presented, complementing previous studies of sulfur-bearing species in the region. The column densities and fractional abundances of these species are measured and together these species account for 10% of the cosmic sulfur abundance in the region. The gas properties derived from the observations are also presented, demonstrating that sulfur bearing species trace a wide range of different gas conditions in the region.
La inmigración española en Argentina y sus dinámicas transnacionales contemporáneas: el caso de los castellanos y leoneses en Buenos Aires
Authors: Merino Hernando Asunción
Published: June 2019

Este trabajo aborda la inmigración española a Argentina de la segunda mitad del siglo XX, décadas después. En el nuevo siglo, encontramos a algunos de aquellos inmigrantes y a sus descendientes trabajando en sus asociaciones y federaciones en la tarea de mantener vivo el recuerdo de su tierra de origen y estableciendo una red densa de contactos con las instituciones en España, en un momento en que la colectividad se ha asimilado a la sociedad argentina. Lejos de resultar paradójico, el caso de los castellanos y leoneses en Buenos Aires muestra cómo el transnacionalismo de determinadas prácticas culturales convive en un escenario de asimilación.
La defensa de Santiago de Cuba al ataque de Vernon de 1741: Principios de fortificación para la guerra en el Caribe
Authors: López Hernández Ignacio J.
Published: June 2019

En julio de 1741, el vicealmirante Edward Vernon, poco después del desastre de Cartagena, dirigirá sus fuerzas hacia Santiago de Cuba, gobernada entonces por el coronel Francisco Cagigal de la Vega, quien con anterioridad al estallido de la guerra dispuso los preparativos para su fortificación y defensa. En este estudio nos proponemos documentar la labor que en este ámbito desarrolló el ingeniero francés Francisco de Langle, a fin de analizar y poner en valor su concepto de fortificación para la guerra en el Caribe, que resultará clave para el éxito de esta empresa.
Los restos de Sus scrofa (Artiodactyla, Mammalia) del yacimiento Pleistoceno de Pinilla del Valle (Madrid, España)

Published: June 2019

Se ha llevado a cabo un estudio morfológico y biométrico de los restos fósiles de Suidos excavados en el yacimiento del Pleistoceno superior de la Cueva del Camino, en el término de Pinilla del Valle (Madrid), comparándolos con los restos de otros yacimientos y con especímenes actuales. El material extraído comprende 47 elementos pertenecientes a un mínimo de 6 individuos, destacando la presencia de restos craneales, muy poco frecuentes en los yacimientos europeos de esta época, y ausentes en yacimientos españoles. Se han comprobado en los restos los caracteres anatómicos típicos de Sus scrofa, confirmándose las condiciones paleoambientales obtenidas del conjunto de la fauna.
Skill-Centered Assessment in an Academic Course: A Formative Approach to Evaluate Student Performance and Make Continuous Quality Improvements in Pedagogy
Authors: Mohiudddin Khalid , Rasool Ashiquee Mohammad , Mohd Mansoor Shariff , Mohammad Rashid Hussain
Published: June 2019

Practices in domain-referenced assessment design and formative course evaluation are not common in still-developing, higher education systems around the world. This paper demonstrates skill-centered assessment and instructional design as a method for evaluating students’ skills performances, and demonstrates how to use the overall results for improving the quality of instruc-tion in a course in computing education. It applies a case study method, describ-ing assessment methods linked to, targeted learning skills and learning domains. The measurements were carried out by the course instructor, adopting a replicable analytic approach. The measured outcomes on each skill provided specific information to guide actions by teachers, to improve course delivery. Results suggest important indicators for teachers to stress in the next cycle of course de-livery in which the students were weak. The study demonstrates an easy-to-apply approach in skill-centered assessment, starting with assessments linked to learning domains, as a means for promoting best practices in formative evaluation in the field of computer education. While the essential principles of this method date back to the literature on criterion-referenced testing and instructional design, the systematic process produces results to support quality improvements in higher education settings where such methods are not the norm.
Plasticity Effect on the Mechanical Behavior of an Amorphous Polymer
Authors: Moulai Ali Boudjellel , Ould Chikh El Bahri , Meddah Hadj Miloud , Bachir Bouiadjra Bel Abbès
Published: June 2019

In the process of forming solid materials, the plastic instability phenomena often control the appearance and performance of the finished product. The study of these phenomena is therefore of great scientific and technological importance. Polymers materials, for example, polyvinyl chloride (PVC) are frequently used in the plastic pipes in pressure vessels and pipelines, which require details that are more serious, it is therefore essential to understand the mechanisms of plastic instability in polymers in order to know how to control them. In order to determine the plastic behaviour of PVC, the true stress-strain response under large plastic deformation was investigated in different stress triaxiality frameworks. A particular attention was given on the volumetric strain evolution and the damage. The effect of stress triaxiality on the fracture strain was also examined. In the second part of this paper, an elasto-viscoplastic behaviour model is presented, with non associated plasticity, damage and coalescence, which represents the observed behaviours of a PVC material under different triaxialities and for three initial void shapes
A New Approach for Calculating Cohesive Energy of Solid Neon Based on the First Principles
Authors: Zheng Xing Rong
Published: June 2019

Based on the first principles and quantum mechanics, a new approach is put forward to calculate the cohesive energy of face-centered cubic solid neon, in which both the two-body and the total many-body interaction potentials are reasonably emphasized by a new combination formula. It shows that the new scheme is a simple and accurate tool to understand the high-pressure behaviors of solid neon, and it will be applied to calculate the compression curves of dense Helium, Argon, Krypton and Xenon at very high pressures. It is expected that this method can be applicable to all rare gas, including the gas, solid, and liquid phase regions, even of molecular systems, ionic systems.

The TiO2 nanoparticles with different Yb doping amount were prepared by a facile sol-gel method. The samples were characterized by XRD, TEM, XPS, UV-Vis, and PL, etc. The influence of Yb-doping on structure and visible light photocatalytic activity of mixed phase TiO2 was evaluated by photocatalytic degradation of methylene blue (MB) under the irradiation of fluorescent lamp. The results show that ytterbium appeared two kinds of Yb3+ and Yb2+ valence state on the surface of TiO2. Ytterbium doping can restrain the phase transfer from anatase to rutile, prevent the grain growth, and increase the surface hydroxyl content. Appropriate amount of Yb doping and the proportions of rutile and anatase mixed phase can effectively inhibit the recombination of photogenerated electron and hole, expand the wavelength range of absorption spectrum, and improve the photocatalytic performance of TiO2. Meanwhile, the photocatalytic activity of the Yb-TiO2 samples was the best under the irradiation of fluorescent light when the sintered temperature T=500°C and n(Yb):n(Ti)=0.009, it was 95.2% within 6 h and significantly higher than 56.4% of pure TiO2 under the same experimental conditions.

Published: June 2019

Deep drawing is a complex process influenced by the geometric parameters of the die-punch system. In the present paper we study the behavior of the semi-finished product, in the process of drawing deep cylindrical parts, using the finite element method and the software package of the ANSYS program. In order to reduce the cost and design time, an analysis of the variation of the radius connection is carried out, resulting in low energy consumption, using the finite element method. By analysing the radius of connection of the plate, we identify future directions useful in substantiating the elaboration of a judicious experimental program and optimizing the geometric shape of the finished parts.

A Holistic Performance Management Approach in Business Networks
Authors: Moritz Markus , Manolache Daniel Silviu , Gheorghe Marian
Published: June 2019

Companies want to achieve a sustainable financial success through process and performance improvements. Increasing the company’s performance is a good way for sustainable success. Typically, the success is measured by process output metrics. This output mirrors the performance of a company’s processes in the end. It is obvious that for being able to cope with complex business network structures in a derivative supply-demand-structure as well as collaboration cooperation incentives, performance needs to be managed across the whole network to strengthen the own network centrality. The present paper contributes to the development of a new holistic Performance Management in business networks. Thus, a Network Performance Wheel - for a more network oriented approach, and a Process Management Balanced Scorecard - to close the gap between internal and external impacts, are introduced. Also, a PM-VICTORY model is launched for implementing the whole network directed Performance Management.

Jointed track is still used to build the secondary lines where the maximum speed does not exceed 100-120 km/h. Jointed track construction is based by the fact that the rails are joined end-to-end via the rail joints in order to assure the continuity of the rolling surface of the rails. The rails are jointed using two metal joint bars (fishplates) bolted to the ends of adjoining rails. The rail joints are featured with small gaps to allow the thermic expansion of the rails when the environmental temperature is higher than that during the fitting. In this paper, an analytical model for the rail joint considering the influence of the joint gap is presented and analysed. The model consists of three Euler-Bernoulli beams, two for the rail ends of the rail joint and the third beam for the two joint bars, connected to the rail ends by a Winkler layer. The concept of weakness of the rail joint (rail joint deflection/continuous rail deflection) is introduced and used to analyse the static behaviour of three types of rail joints used at CFR (Romanian Railways). The influence of the joint bars length and bending stiffness, and the influence of the joint gap length upon the rail joint weakness is pointed out.
Principles Regarding the Structuring of the Hybrid Models in Engineering

Published: June 2019

Advancements in computer science offer new concepts and instruments to be used in the modelling of the complex phenomena. Apart from the commercial software applications, researchers may use performant data processing methods based on the latest computing techniques in order to create original software instruments. A hybrid model consists of a series of studies of various types: theoretical (analytical and/or numerical) and experimental. A hybrid model may be represented as a flowchart, each study being an element of the data flow representation. Each element, i.e. distinct study, has input data and output information expressed as data files and/or as visualizations meant to graphically synthesize the results. The output data of an element is the input data of the following study, in this way being developed the flowchart of the hybrid model, similar to the method used in the Unified Modelling Language. The rapid development of the hybrid models depends on the degree of readiness regarding the software libraries to be created. The original software libraries solve two types of problems: solvers of the distinct studies and data integration in the wider context of the hybrid model. The distinct studies which model a particular aspect of the phenomenon are used to automatically and accurately generate the input data of the ‘main’ model which is usually created using a commercial software application. In this way, the distinct studies may be represented as satellites orbiting the ‘main’ model. The paper presents the basic concepts used to conceive hybrid models and it is inspired by the software development activity for research projects in the latest 30 years.

Adipose regulatory T cells (aTregs) have emerged as critical cells for the control of local and systemic inflammation. In this study, we show a distinctive role for the transcriptional regulator Id2 in the differentiation, survival, and function of aTregs in mice. Id2 was highly expressed in aTregs compared with high Id3 expression in lymphoid regulatory T cells (Tregs). Treg-specific deletion of Id2 resulted in a substantial decrease in aTregs, whereas Tregs in the spleen and lymph nodes were unaffected. Additionally, loss of Id2 resulted in decreased expression of aTreg-associated markers, including ST2, CCR2, KLRG1, and GATA3. Gene expression analysis revealed that Id2 expression was essential for the survival of aTregs, and loss of Id2 increased cell death in aTregs due to increased Fas expression. Id2-mediated aTreg depletion resulted in increased systemic inflammation, increased inflammatory macrophages and CD8+ effector T cells, and loss of glucose tolerance under standard diet conditions. Thus, we reveal an unexpected and novel function for Id2 in mediating differentiation, survival, and function of aTregs that when lost result in increased metabolic perturbation.

Published: June 2019

Requirements off Automotive Tier1s and OEMs Klaus Pietrczak JCET Group, 46429 Landing Parkway, Fremont, CA 94538 Klaus.Pietrczak@statschippac.com The automotive market size for power and discrete devices is growing at a rate of greater than 7 percent. Market drivers for this growth include ADAS, Infotainment and Powertrain. Getting an automotive device from initial specification to high volume manufacturing (HVM) can take four years compared to the typical three to six months it takes a consumer device. The requirements for automotive devices are much more complex. Increasing electronic content and zero failure over 15 years of lifetime are the major drivers for the ever increasing reliability requirements. The major document for any automotive device is the Production Part Approval Process (PPAP). This presentation will show the required content for the PPAP and which roles in an organization will contribute to it. There will also be a deeper dive into the three major automotive standards: IATF16949, AIAG and AEC. For each standard covered in-depth looking at the purpose, what the goal of the standard is, and a few examples for better understanding. Also covered will be the fact that even with all of these standards, not everything is covered. The device manufacturer having specific requirement on top of the standard requirements are more the standard rather than the exception. We will go into detail regarding who has to deliver what to which section and how they are all linked and interacting. The content on the standards will be completed by a look at the upcoming ISO26262-11, its intent, scope and expected influence on Semiconductor and OSATs. Finally, a look to some of the less defined but still important pieces of the puzzle. Examples of these include failure analysis procedure, product change/cancellation notification and data retention. While not an exhausting list, more often than not each is an important part of the business. An explanation of the purpose and typical requirements for these will be presented. This comprehensive review will give anyone targeting automotive business an overview of all that is required for automotive devices and the timeline to expect to get to HVM.
