Authors: Correa Christiane , Jucá José Fernando , Motta Eduarda
Published: November 2015

RESUMO Apresenta-se uma análise da resistência ao cisalhamento de resíduos sólidos urbanos com redução de termoplásticos em aterros sanitários. Através de ensaios de laboratório, foi realizada uma análise comparativa entre os dois principais termoplásticos (polietileno de alta e baixa densidade) presentes em aterros sanitários brasileiros. Investiga-se, a partir de ensaios de resistência à tração dos plásticos e de ensaios de cisalhamento direto de amostras preparadas com diferentes percentagens de plásticos misturados a um material granular, simulando resíduos sólidos estabilizados, a variação dos parâmetros de resistência dos RSU caso as sacolas plásticas sejam retiradas dos supermercados. Os resultados confirmam a importância dos plásticos, pois são eles os responsáveis pelos valores elevados dos parâmetros de resistência, devido às forças de tração provocadas por estas fibras.
Estimativa da geração de resíduos de equipamentos elétricos e eletrônicos de origem domiciliar: proposição de método e aplicação ao município de São Paulo, São Paulo, Brasil

Published: November 2015

RESUMO Conhecer a geração de resíduos de equipamentos elétricos e eletrônicos (REEE) é fundamental para sua gestão. O fluxo domiciliar de EEE é complexo, pois tem seu descarte associado a fatores tecnológicos, econômicos e comportamentais. O artigo apresenta método para estimativas de REEE de origem domiciliar: estoque de equipamentos em uso, armazenados e descartados, e do potencial de geração de resíduos. O método aplicado ao município de São Paulo, São Paulo, resultou em 71,9 milhões de EEE, dos quais 8,8 milhões (12,2%) fora de uso. O valor médio de EEE correspondeu a 18,2 EEE por domicílio; média per capita de 5,3 EEE por habitante. A média de descarte per capita estimada resultou em 4,8 kg.hab-¹.ano-¹. O potencial de geração de resíduos a partir dos EEE fora de uso variou entre 2,9 a 6,0 kg.hab-¹.ano-¹. O método proposto proporcionou qualidade às estimativas, resultando em importantes indicadores para a gestão.
Análise da gestão e gerenciamento dos resíduos de serviços de saúde (RSS) do Hospital de Emergência de Macapá, Amapá, Brasil
Authors: Maders Gláucia Regina , Cunha Helenilza Ferreira Albuquerque
Published: November 2015

RESUMO No Estado do Amapá, localizado na região norte do país, a falta de informações sobre os resíduos dos serviços de saúde (RSS) impossibilita uma avaliação da gestão e gerenciamento, especialmente do seu manejo, que apresenta problemas em todas as etapas, da geração à disposição final. Esta pesquisa teve como objetivo produzir informações sobre os RSS no hospital de pronto socorro do estado: o Hospital de Emergência, localizado na capital Macapá. O estudo de caso se propôs a analisar a gestão e o gerenciamento dos RSS intraunidade com o apoio de instrumentos (questionários, formulários e estudo gravimétrico) e técnicas diversas (observação, entrevistas, pesquisa documental e bibliográfica). Os resultados indicam taxa de geração de 5,273 kg de RSS/leito ocupado/dia, e o Centro de Tratamento de Queimados (CTQ) foi o setor que apresentou a maior taxa de geração: 5,990 kg.leito-1.dia-1. Quanto à composição, 35,01% dos RSS são dos grupos A, B e E, porém quando segregados durante a caracterização gravimétrica, o percentual destes resíduos diminuiu para 25%. A segregação dos RSS é deficiente, pois apresentou mistura de até 79,6% de resíduos comuns (grupo D) acondicionados como resíduos infectantes (grupo A) e 15,5% destes acondicionados como resíduos comuns. A inexecução do Plano de Gerenciamento dos Resíduos dos Serviços de Saúde (PGRSS) do Hospital, traduzida na falta de atitudes gerenciais positivas e educação continuada, somada à inoperância dos órgãos de fiscalização são as causas desse cenário.
Os fundamentos da física dos férmions de Dirac sem massa em (1+2)-D e o grafeno
Authors: Dartora C. A. , Jimenez Miguel J. Saldaña , Zanella Fernando
Published: November 2015

O grafeno é um material alotrópicoo do carbono, formado por uma monocamada de átomos de carbono arranjados em uma estrutura cristalina de favo de mel (ou honeycomb), podendo ser obtido por diversos métodos experimentais, sendo a esfoliação do grafite o modo mais simples. Trata-se do primeiro material verdadeiramente bidimensional porque é constituído de um única camada atômica, em contraste com estruturas que se comportam como bidimensionais, porque uma das dimensões é muito reduzida em relação às outras duas, mas essa dimensão diminuta ainda assim é constituida de várias camadas atômicas. Uma das mais espetaculares previsões teóricas para o grafeno, confirmada experimentalmente, é a de que os elétrons se comportam como férmions de Dirac sem massa nos chamados pontos de Dirac, ou seja, agem efetivamente como partículas “relativísticas” sem massa em um espaço-tempo de (1+2) dimensões, sendo uma dimensão temporal e duas espaciais. Esse comportamento exótico abre o campo para emular física de altas energias em matéria condensada, além de prometer uma revolução na eletrônica de alta velocidade. O objetivo desse trabalho é apresentar os fundamentos da física de férmions de Dirac e como surge o modelo efetivo no grafeno. Entendemos que há pouca literatura referente ao assunto em idioma português. Além disso, esse sistema físico é muito útil como introdução às teorias de campos relativísticas e aos métodos de segunda quantização.
Panorama geral da obra astronômica de Kepler

O uso de vídeos curtos para ensinar tópicos de semicondutores
Authors: Freitas Frederico Campos , Oliveira Adilson Jesus Aparecido de
Published: November 2015

A cada dia se torna mais frequente o uso de aparelhos eletrônicos que, em sua grande maioria, estão baseados em diodos e transistores semicondutores. Compreender alguns conceitos ligados a esses materiais pode ser muito importante para entender e se relacionar melhor com tais aparelhos. Apesar de essa ser uma constatação que aparece também em documentos oficiais e nos parâmetros curriculares nacionais (PCN), o que se observa na prática é um número muito reduzido de propostas neste sentido. Assim, o objetivo desse trabalho foi descrever o uso de uma sequência de quatro vídeos curtos para ensinar tópicos de semicondutores no Ensino Médio. Eles foram aplicados em duas turmas de terceiro ano do Ensino Médio, num total de 72 estudantes. Após cada vídeo, foi entregue um questionário com 16 itens de Likert, a fim de medir as atitudes dos estudantes em relação a alguns conceitos abordados nos vídeos. Analisando os resultados obtidos nos questionários, observou-se que a proposta se mostrou bastante eficaz, principalmente no que diz respeito à motivação dos alunos em estudar o assunto. A maior parte dos conceitos foi bem assimilada, e as poucas dificuldades apresentadas estavam de acordo com a literatura. Isso sugere que o uso de vídeos curtos é uma estratégia que pode ser mais utilizada, principalmente devido à sua versatilidade e à pequena demanda de recursos técnicos.
Living under attack in a one-dimensional virtual world
Authors: Faella O. , Luca R. De
Published: November 2015

We present a kinematics problem in the framework of a videogame. Students are asked to find possible extensions of a safety zone on the x-axis to the right of an indestructible defense wall of height h placed at x = d in which the point-like balls, fired by strange attackers from the origin O of an Oxy reference system, cannot fall. We solve this problem analytically and suggest generalizations. This exercise may be appealing to students who play videogames, since it is proposed by recalling typical situations in simple virtual reality.

Published: November 2015

Nesse trabalho estudamos a resolução de um caso particular da equação hipergeométrica confluente, a equação de Bessel de ordem p, utilizando a teoria do cálculo de ordem não inteira. Em particular, a fim de comparar com a literatura existente, expomos os resultados da nossa investigação sob o rigor do formalismo matemático e levantamos alguns questionamentos a respeito da interpretação dos operadores de Riemann-Liouville quando agindo em certas funções. Para tanto, introduzimos as principais formulações dos operadores fracionários (Riemann-Liouville), assim como o operador de integrodiferenciação fracionária que é a tentativa de se expressar ambos operadores de integração e diferenciação fracionárias de forma unificada.
Partículas e antipartículas no cone de luz
Authors: Sales Jorge Henrique , Suzuki A. T. , Soriano L. A.
Published: November 2015

Na teoria quântica de campos usual, descrita no espaço-tempo de Minkowski, os conceitos de partícula e antipartícula surgem associados aos estados de energia positiva e negativa respectivamente. Nesse artigo focando como público alvo alunos de pós-graduação em Física, discutimos de maneira pedagógica como esses conceitos podem ser ou não transferidos quando fazemos uma mudança de coordenadas, do espaço-tempo de Minkowski para as coordenadas do cone de luz. Concluímos que nessas novas coordenadas temos uma arbitrariedade na escolha, uma vez que o sinal da energia fica atrelado ao sinal da componente longitudinal do momento no cone de luz. Embora haja essa arbitrariedade, a correlação de sinal que existe entre a energia e o momento longitudinal implica profundas consequencias físicas. Momentos positivos implicam energias positivas e momentos negativos implicam energias negativas. Isso significa, por exemplo, que no vácuo quântico da frente de luz não pode haver produção de pares partículas e antipartículas, ao contrário do que ocorre no espaço de Minkowski usual.

Lifter - High voltage plasma levitation device
Authors: Cattani M. , Vannucci A. , Souza V. G.
Published: November 2015

This paper shows in detail the construction and operation of an apparatus that levitates when submitted to voltages greater or of the order of 20 kV. This device, which basically corresponds to an asymmetric capacitor, is commonly known in the literature by the name ‘lifter’. It also will be shown in this article, through rather simplified calculations, that the physics grounds of the observed levitation effect are intrinsically related to the transference of linear momentum of the ions (positive or negative) to the surrounding atmosphere. These ions are produced within the conductor of very small curvature (hence, great electrical potential) due to the so called corona effect and, once created, they are immediately accelerated by the intrinsic electric field lines configuration, producing multiple collisions with the air molecules, causing the transference of momentum and, therefore, provoking the observed lifter ascendant impulsion.

Uma recriação dos modelos é apresentada nesse artigo, além da sua formulação algébrica e da descrição das atividades pedagógicas desenvolvidas. A atividade foi considerada motivadora para os estudantes, por permitir uma maior compreensão sobre os modelos da óptica geométrica e também sobre as práticas científicas.
Parametric analysis of AAR influent factors on thin-walled columns
Authors: Madureira E. L. , Rodrigues E. C.
Published: November 2015

ABSTRACTThe chemical reaction involving the alkalis of the cement and some minerals of the concrete aggregates, the Alkali-Aggregate Reaction or, simply, the AAR, promotes swelling and material damages. Despite the development stage of the researches on this pathology effects, its solution modeling still lacks refinement. The numerical simulation is an important resource for the structural damages evaluation due to AAR, and their repairs. The aim of this work is the numerical simulation of concrete thin-walled columns, affected by the AAR, from the finite element approximation on an orthotropic nonlinear framework, and a thermodynamic model designed to the assessment of the AAR swelling, with highlight on the compressive stress, the reinforcement and the temperature influences on the phenomenon. The obtained results revealed that the AAR induced the concrete strength decrease and the consequent reduction in preventive safety margin to the material failure, being more precocious at higher temperatures.
Bond strength between stell-concrete and between concretes with different ages in structural rehabilitation

Published: November 2015

ABSTRACTIn inspections of buildings, it is common to find structures that, well before reaching its useful life longer require repairs and reinforcements. This study examined the bond strength between concrete of different ages and between steel and concrete, focusing on the recovery of reinforced concrete structures. To analyze the bond between concrete of different ages, trials with specimens receiving three different types of treatments at the interface between the concrete were performed: brushing; brushing and mortar equal to concrete of substrate and brushing and epoxy layer. Indirect tensile tests and oblique and vertical shear tests at the interface were made . The bond stress between steel and concrete was evaluated by pull out test under the conditions of the bar inserted in the still fresh concrete and when inserted in the hardened concrete with epoxy. Results showed increased bond strength by indirect tensile stress of 15% and 37%; 4% and 12% for the adherence test by oblique shear, and 108% and 178%, for the testing of vertical shear, respectively, for the specimens whose interfaces have received, in addition to brushing, layer of mortar and epoxy bridge, compared to those who received only brushing. Insignificant loss (about 0.52%) of bond stress was noticed for pull out test of steel bar when compared with test results of the specimens that had steel bar inserted in the concrete in the hardened state with epoxy adhesion bridge, with those who had inserted steel bar in fresh concrete.
Assessment of cover to reinforcement in slabs using different spacer and tying distances
Authors: Maran A. P. , Barreto M. F. F. Menna , Rohden A. B. , Molin D. C. C. Dal , Masuero J. R.
Published: November 2015

ABSTRACTGiven that the durability of structures is directly related to the thickness of the cover to reinforcement, it is essential to ensure minimum cover is achieved when building a structure. However, studies show that this is not always the case. One of the reasons for the this problem is the lack of indication, in structural projects, of the positioning of spacers. This situation is compounded by the lack of standards and regulations on the use of spacers (i.e. minimum quantities and required layout). This study assesses three different spacer distances and two different tying distances in order to examine the influence of these factors in the cover to reinforcement. To achieve so, three slabs were prepared in situ using different arrangements. After demoulding, cover thickness was determined using a digital covermeter. It was observed that the factors investigated have a significant influence in the final cover.

ABSTRACTThe effects of the inclusion of steel fibers in concrete have been widely studied in order to investigate possible changes in mechanical properties, such as the increase in tensile strength, ductility, stiffness, toughness (energy absorption capacity), and durability. An immediate consequence of this addition is the mitigation of concrete's brittle behavior, so that the material meets new quality requirements. In this context, it is important to study the spatial distribution of the entire internal structure of these materials. Three-dimensional computed microtomography is a non-destructive inspection technique used to characterize the internal structures of various materials based on X-ray interaction with the inspected object. Topological and morphological properties can be obtained directly in three dimensions by means of mathematical reconstruction of the radiographs, which allows analyzing, for example, porosity and distribution of objects. In this context, the aim of this study is to investigate the spatial distribution of steel fibers, as well as of porosity in reinforced concrete samples. To this end, we used a microtomography system calibrated to operate at a voltage of 80 kV, electric current of 100 μA and a pixel size equal to 24 µm. The results showed low porosity and that the steel fibers were not uniformly distributed throughout the sample.

The phospholipase A2 receptor (PLA2R1) is the major autoantigen in idiopathic membranous nephropathy. However, the value of anti-PLA2R1 antibody titers in predicting patient outcomes is unknown. Here, we screened serum samples from 50 patients positive for PLA2R1 for immunoreactivity against a series of PLA2R1 deletion mutants covering the extracellular domains. We identified reactive epitopes in the cysteine-rich (CysR), C-type lectin domain 1 (CTLD1), and C-type lectin domain 7 (CTLD7) domains and confirmed the reactivity with soluble forms of each domain. We then used ELISAs to stratify 69 patients positive for PLA2R1 by serum reactivity to one or more of these domains: CysR (n=23), CysRC1 (n=14), and CysRC1C7 (n=32). Median ELISA titers measured using the full-length PLA2R1 antigens were not statistically different between subgroups. Patients with anti-CysR–restricted activity were younger (P=0.008), had less nephrotic range proteinuria (P=0.02), and exhibited a higher rate of spontaneous remission (P=0.03) and lower rates of renal failure progression (P=0.002) and ESRD (P=0.01) during follow-up. Overall, 31 of 69 patients had poor renal prognosis (urinary protein/creatinine ratio >4 g/g or eGFR<45 ml/min per 1.73 m2 at end of follow-up). High anti-PLA2R1 activity and epitope spreading beyond the CysR epitope were independent risk factors of poor renal prognosis in multivariable Cox regression analysis. Epitope spreading during follow-up associated with disease worsening (n=3), whereas reverse spreading from a CysRC1C7 profile back to a CysR profile associated with favorable outcome (n=1). We conclude that analysis of the PLA2R1 epitope profile and spreading is a powerful tool for monitoring disease severity and stratifying patients by renal prognosis.

Endothelial dysfunction is a central pathomechanism in diabetes-associated complications. We hypothesized a pathogenic role in this dysfunction of cathepsin S (Cat-S), a cysteine protease that degrades elastic fibers and activates the protease-activated receptor-2 (PAR2) on endothelial cells. We found that injection of mice with recombinant Cat-S induced albuminuria and glomerular endothelial cell injury in a PAR2-dependent manner. In vivo microscopy confirmed a role for intrinsic Cat-S/PAR2 in ischemia–induced microvascular permeability. In vitro transcriptome analysis and experiments using siRNA or specific Cat-S and PAR2 antagonists revealed that Cat-S specifically impaired the integrity and barrier function of glomerular endothelial cells selectively through PAR2. In human and mouse type 2 diabetic nephropathy, only CD68+ intrarenal monocytes expressed Cat-S mRNA, whereas Cat-S protein was present along endothelial cells and inside proximal tubular epithelial cells also. In contrast, the cysteine protease inhibitor cystatin C was expressed only in tubules. Delayed treatment of type 2 diabetic db/db mice with Cat-S or PAR2 inhibitors attenuated albuminuria and glomerulosclerosis (indicators of diabetic nephropathy) and attenuated albumin leakage into the retina and other structural markers of diabetic retinopathy. These data identify Cat-S as a monocyte/macrophage–derived circulating PAR2 agonist and mediator of endothelial dysfunction–related microvascular diabetes complications. Thus, Cat-S or PAR2 inhibition might be a novel strategy to prevent microvascular disease in diabetes and other diseases.

Published: November 2015

The pathogenesis of nephrotic syndrome is unclear. However, the efficacy of rituximab, a B cell–depleting antibody, in nephrotic syndrome suggests a pathogenic role of B cells. In this retrospective study, we determined by flow cytometry levels of B and T cell subpopulations before and after rituximab infusion in 28 pediatric patients with frequently relapsing or steroid–dependent nephrotic syndrome. At baseline, patients had lower median percentages of transitional and mature B cells than age–matched healthy controls (P<0.001). Rituximab induced full depletion of B cells (<1% of lymphocytes). At 1 year, most patients exhibited complete total and mature B cell recovery, whereas memory B cell subsets remained significantly depleted. Total T cell concentration did not change with rituximab, whereas the CD4+/CD8+ T cell ratio tended to increase. Fourteen patients relapsed within 24 months, with a median follow-up of 11.2 months (interquartile range, 8–17.7 months). We observed no difference at baseline between nonrelapsing and relapsing patients in several clinical parameters and cell subset concentrations. Reconstitution of all memory B cell subpopulations, number of immunosuppressive drugs, and dose of tacrolimus during the last 4 months of follow-up were predictive of relapse in univariate Cox regression analysis. However, only delayed reconstitution of switched memory B cells, independent of immunosuppressive treatment, was protective against relapse in multivariate (P<0.01) and receiver operator characteristic (P<0.01 for percentage of lymphocytes; P=0.02 for absolute count) analyses. Evaluation of switched memory B cell recovery after rituximab may be useful for predicting relapse in patients with nephrotic syndrome.
Phytotoxicity of Sicyos deppei during tomato germination and its effects on the role of ABA and cell wall enzymes
Authors: Lara-Núñez Aurora , Ventura-Gallegos José Luis , Anaya Ana Luisa , Cruz-Ortega Rocío
Published: November 2015

Sicyos deppei is a harmful weed that grows in central Mexico, decreasing crop productivity by allelochemical release via lixiviation of the aerial organs through raining. S. deppei aqueous leachate is phytotoxic to tomato seed germination causing various metabolic alterations, such as high levels of abscisic acid, which delay germination and inhibit radicle growth. To determine whether abscisic acid catabolism was involved in the delay of germination caused by S. deppei , tomato seeds were exposed to diniconazole, an ABA catabolism-inhibitor, and subsequently the activity of cell wall-degrading enzymes (endo-?-mannanase, ?-galactosidase, exo-polygalacturonase, and b-1,3-glucanase) was estimated in the presence of ABA, diniconazole and S. deppei aqueous leachate. Results showed that during germination, there is a delay in ABA degradation and the activity of the four cell wall-degrading enzymes evaluated was inhibited. Cell cycle was analyzed to characterize the inhibition of radicle growth during post-germination in the roots of treated seedlings. The phytotoxic aqueous leachate of S. deppei interfered with it, altering the expression of two cell cycle marker genes CDKB2;1 and CycB2;1 , thereby reducing cell division. In summary, the delay in tomato germination through S. deppei leachate reflects first that there is a delay in ABA catabolism, and second there is an alteration of cellular processes that interfere with cell cycle and inhibit radicle growth during postgermination.

Published: November 2015

Studying the way in which art is employed for learning languages by girls or boys will reveal the attitudes and beliefs of a society. The best way we can analyze the differences laying in between girls and boys in the real life is to observe them using art as a tool while learning. In this study the researcher has focused mainly on learning English as a second language. This study is an attempt to explore the status of gender differences when applying art. The main purpose is to provide an inclusive collection of gender differenceswhen applying art in order to learn the second language. As a whole asymmetries between boys and girls are depicted through art as a medium. Overt expression of art appreciation and application is observed in different terms. This paper elaborates on the above theme by providing practical documents of a limited number of students from the upper level families of the northern part of the Capital of Iran, Tehran. The participants are in pre-school level. Both classes are taught by the same instructor. The proper teaching amount is almost the same. The author has taught both classes through holistic approach, while a class is held only for boys and the other held only for girls based on Iran Educational System rules and regulations.Keywords: Holistic Education, Arts, indirect teaching, Boys and Girls difference

New approaches in art education and the use of technology
Authors: Zor Aydın , Tepecik Adnan
Published: November 2015

In order to train individuals capable of keeping pace with the information and communication age we are living in, making use of technological developments and using all the opportunities of the present age in educational field is crucial.
