Surface potential decay of functional dielectrics after polarization
Authors: Zhang Jia-wei , Yin Chao , Liu Rui-tong , Zhao Yong-sheng
Published: August 2016

High voltage polarization domains in functional dielectrics and the ability to orient them with an external applied electric field lead to the development of a variety of applications of energy conversion from energy harvesting to information storage and reading. Voids are often generated at the bond interface during the production process of polymer films, which can break down easily in the process of polarization with high voltage, but the voids inside dielectric materials play an important role in charge storage and maintenance if the materials are oriented to the application of electrostatic generator, sensor, actuator and transducer etc. Meanwhile, a polymer matrix doped with a small amount of nanoparticles can suppress charge formation and increase surface charge decay rate. Results obtained in this paper show that polymer materials with microvoids have better maintenance properties of space charge compared with nanocomposite polymer materials. The research result is of important reference value and practical significance in the field of insulation and applications of functional dielectric materials.
Numerical simulation of plain concrete specimens with micromechanical model and simple lattice model
Authors: Teng Susanto , Li Qingliu , Liu Yu
Published: August 2016

In this paper, a recently proposed micromechanical model for concrete is combined with a simple lattice model to simulate the behaviours of plain concrete specimens under tension, compression and three-point bending. The Mori–Tanaka method based micromechanical model for concrete considers the microcracks around the mortar–coarse aggregate interface and the aligned coalesced cracks in the concrete. It explicitly correlates the mechanical properties of concrete with the properties of its constituents such as mortar and coarse aggregates. The adopted simple lattice model, in which the axial interaction between neighbouring points is considered as a truss, does not need to generate grain structure and is thus easy to implement. Hence, this combination can be used to investigate the influences of the concrete constituents' properties on the behaviours of the concrete specimens in a simple way. The predicted deformation responses and crack patterns from the computational model are generally in agreement with the experimental observations.

Authors: Rogério Fernando Raphael Pinto Guedes , Santos David Jeferson dos , Desiderio André Felipe Silva , Freitas Eliane Regina Ferreira Sernache de
Published: August 2016

Introduction: The pronation foot is related to numerous musculoskeletal disorders, in order to reverse this biomechanical dysfunction has often been used to low-Dye taping (LDT). Objective: Evaluate the acute effect of the application of low-Dye taping (LDT) on dynamic Baropodometric parameters (DBP) in subjects with foot overpronation. Method: They evaluated 17 feet by baropodometric dynamic by midgait protocol. The pressure measurements were obtained by planting stratification of the foot region in eight shades in LDT conditions and without taping. Results: The Student t test for paired samples showed a significant reduction of peak plantar pressure, mean plantar pressure, integral pressure / time largely masks studied without however generate substantial increases in other plantar regions. Conclusion: The application of LDT proved to be an efficient way to reduce the DPB in subjects with foot overpronation.
Joint immobilization: effects on bone tissue of obese and malnourished animals.
Authors: Rissi Renato , Lemos George Azevedo , Pires Ivan Luiz de Souza , Camargo Rafael Ludemann , Palomari Evanisi Teresa
Published: August 2016

Introduction: The immobilization induces an unbalanced bone metabolism, followed by rapid bone loss and consequent loss of the mechanical function of the bone. In general, the obesity and protein malnutrition conditions affect a large number of people worldwide, and both morbidities have specific characteristics that may cause deleterious effects on bone tissues of patients by different mechanisms. Objective: the present study aimed to verify experimentally if the joint immobilization protocol causes bone tissue atrophy in obese and undernourished animals. Method: 20 adult male mice (C57/BL6) were used, divided into four groups (N=5): Control Group (CG), Immobilized Control Group (ICG), Immobilized Obese Group (IOG) and Immobilized Malnourished Group (IMG). The histomorphometric analysis of the tibia quantified the number of osteocytes, cortical thickness and diameter of the medullary canal. Results: The study involving the tibia of the animals showed statistical differences in variables analysis. All immobilized groups showed lower amount of osteocytes in the evaluated tissue and increase in diameter of the spinal canal when compared to the CG. The cortical thickness was reduced in ICG and IMG groups when compared to the CG. Conclusion: The used joint immobilization protocol caused bone atrophy in the studied animals. The association between obesity, malnutrition and joint immobilization conditions cause increase in bone tissue atrophy.

Published: August 2016

Introduction: Prescription of resistance training (RT) is increasing among teenagers, requiring further studies to investigate the effects on this population. Objective: To examine the different orders on exercises sequence and its influence on the number of repetitions in teenager. Methods: Participated in the study 12 voluntarily male teenagers (14.91 ± 0.79 years, 1.69 ± 8.61 cm, 62.24 ± 7.26 kg) without experience in RT. After 48 hours of the last session of 10 repetitions maximum (10RM) test, subjects performed one of the four sequences of exercises in a counterbalanced crossover design. Four different sequences were also performed with a interval of 48 hours. All sequences were three sets of each exercise with 10RM load, with two-minute intervals between sets and exercises. The order of exercises was the sequence 1: bench press (BP), pulldown (PD), machine shoulder press (SP), biceps curl (BC) and triceps (TR); Sequence 2: TR, BC, SP, PD and BP; the sequence 3: Leg press (LP), leg extension (LE) and leg curl (LC); Sequence 4: LC, LE and LP. Results: Significant differences were observed (p <0.05) in the total number of repetitions for the BP exercises, SP, BC and TR for the sequence of the upper limbs and for the lower limbs and the LP and LE exercises. Conclusion: The results suggest that the performance of the average number of repetitions for sessions conducted with RT intensity of 10RM in teenagers was influenced by the different kind of exercises in both upper and lower limbs.

Published: August 2016

The definition of a user model supports personalization in computer-based systems. For a personalized system in health, which supports the promotion of healthy habits and lifestyles, in particular physical activity and healthy diet, a user model according to the ISO/TR 14292 standard for Personal Health Records [PHR] is proposed. The description of the standardized user model includes: a characterization of the user model; the proposed user model according to the ISO standard; the relationships and inferences of the user model; and reference architecture for the system to be developed. Finally, a prototype with a small dataset is implemented and some possible mockups supporting the proposed architecture are designed.
Remote Sensing for Agricultural Crops Based on a Low Cost Quadcopter
Authors: Campo Arcos Liseth Viviana , Corrales Muñoz Juan Carlos , Ledezma Espino Agapito
Published: August 2016

This paper presents a proposal for information gathering from crops by means of a low-cost quadcopter known as the AR Drone 2.0. To achieve this, we designed a system for remote sensing that addresses challenges identified in the present research, such as acquisition of aerial photographs of an entire crop and AR Drone navigation on non-planar areas arises. The project is currently at an early stage of development. The first stage describes platform and hardware/software tools used to build the proposed prototype. Second stage characterizes performance experiments of sensors stability and altitude in AR Drone, in order to design an altitude strategy control over non-flat crops. In addition, path planning algorithms based on shortest route by graphs (Dijkstra, A* and wavefront propagation) are evaluated with simulated quadcopter. The implementation of the shortest path algorithms is the beginning to full coverage of a crop. Observations of quadcopter behavior in Gazebo simulator and real tests demonstrate viability to execute the project by using AR Drone like platform of a remote sensing system to precision agriculture.

Authors: Delvalle  Arroyo Pablo Emilio , Fory Aguirre Carlos Andrés , Serna Ramírez Juan Manuel
Published: August 2016

Los autómatas celulares bidimensionales constituyen una potente herramienta para la  simulación de sistemas discretos complejos, son útiles en el tratamiento de fenómenos propagativos como epidemias  o incendios. El presente trabajo propone una serie de mejoras teóricas, funcionales y aplicativas  al estudio publicado en 2009 por Hoya, Martin del Rey, y Rodríguez,  específicamente orientadas al control de los patrones de propagación en autómatas celulares con reticulados homogéneos de tamaño variable, lo que permite la simulación de  conjuntos celulares inmunes  que actúan como barreras en los entornos estudiados. Como agente propagante se utilizó el modelo epidemiológico Susceptible-Infectado-Recuperado [SIR] de recuperación  de la influenza tipo A. El trabajo se desarrolló usando MATLAB®, lo que resultó en simulaciones más  realistas  y versátiles, que parecen ajustarse de manera más fiel a las observaciones realizadas en patrones conocidos de influenza.

Authors: Correa Valencia Maritza , Aragón Chamorro Alexander
Published: August 2016

The link between academia, government, and business to improve the development and appropriation of knowledge in certain topics, such as logistics, is being promoted in Colombia. One of the key issues of teaching logistics is try to bring to actual work contexts, problems that can be handled by people who do not have experience. The incorporation of Information and Communications Technologies (ICT) in academic environments supports the training of professionals in different fields. The tele-operated laboratory for logistics operations called Internet2 way [TELEOPLOGIS] is a project focused on the development and implementation of a remote laboratory where an integrated and didactic manufacturing cell, some robot manipulators, and specific pieces of software are used for the teaching of logistics operations. This laboratory includes the development of guidelines and academic workshops with two approaches: teleoperation systems for discrete events, and manufacturing cells that transform the cell nodes into elements of logistics operations. We achieved acceptable results in both remote operations and in practices that currently are in progress.

Análise da produção e comercialização do pescado no Brasil
Authors: Kirchner Rosane Maria , Chaves Magda Antunes , Silinske Jaqueline , Essi Liliana , Scherer Mônica Elisa , Durigon Emerson Giuliani
Published: August 2016

A aquicultura vem sendo apontada como um setor de atividade de relevância sócio-ambiental por seus potenciais benefícios ou pelos impactos ambientais, bem como por seu valor estratégico em termos de segurança alimentar mundial e, também, econômicos. Poucos são os países com tamanha disponibilidade de ambientes propícios a aquicultura como o Brasil, sendo uma das atividades agropecuárias com maior potencial de crescimento na atualidade. Também a pesca exerce um papel econômico e social relevante. Mapear tais atividades econômicas no país é tarefa essencial, tanto para o planejamento de estratégias de crescimento do setor, aprimoramento de tecnologias, bem como para o planejamento ambiental. Visando auxiliar no mapeamento das atividades aquícolas no Brasil, foi realizado um levantamento dos estabelecimentos aquícolas e de pesca nas regiões brasileiras com relação à produção e venda, com base em dados oficiais do ano de 2006 (IBGE), indicando regiões de destaque para cada cultura, refletindo sobre potenciais de crescimento e riscos ambientais a serem considerados. Os resultados obtidos demonstram que a região Nordeste se destaca tanto em número de estabelecimentos aquícolas quanto em produção de peixes e camarões, enquanto a região Sul destaca-se em número de estabelecimentos produtores de ostras, vieiras e mexilhões. Entretanto, observou-se que a produção apresentou potencial de aumento, sendo essa última década estratégica para planejamento de ampliação do setor no país, de modo sustentável e socialmente justo.
Nitrogênio mineral na soja integrada com a pecuária em solo arenoso
Authors: Balbinot Junior Alvadi Antonio , Franchini Julio Cezar , Debiasi Henrique , Werner Flávia , Ferreira André Sampaio
Published: August 2016

No Brasil, a soja tem sido introduzida em regiões que apresentam solos arenosos e clima tropical, sendo muitas vezes integrada com a pecuária. A demanda da oleaginosa por nitrogênio(N) é suprida pela mineralização da matéria orgânica do solo e pela fixação biológica do N. No entanto, há questionamentos quanto ao efeito da adubação nitrogenada na cultura da soja cultivada em solos arenosos, com alta quantidade de palha de gramíneas. Objetivou-se com este trabalho avaliar o desempenho de duas cultivares de soja, em solo arenoso, após dois anos com pastagem de Urochloa brizantha, submetidas a diferentes doses (20 e 45 kg de N ha-1) e épocas de aplicação (semeadura, no início do florescimento e no início do enchimento dos grãos) de N em solo com elevada quantidade de palha de U. brizantha. Foram conduzidos dois experimentos no Noroeste do Paraná, Brasil, um com a cultivar BMX Potência RR e outro com a cultivar BRS 360 RR, em um solo muito arenoso (11% de argila). Ao todo, foram testados sete tratamentos (fatores combinados e a testemunha), arranjados em delineamento de blocos casualizados, com quatro repetições. Em solo arenoso, com alta quantidade de palha de pastagem de U. brizantha, a adubação nitrogenada, aplicada em diferentes doses e estádios de desenvolvimento da soja, cultivares BMX Potência RR e BRS 360 RR, não influencia a partição de fotoassimilados entre folhas e caules, o teor de N nas folhas, a produtividade, os componentes de rendimento e os teores de óleo e proteína nos grãos.

Objetivou-se, com este trabalho, determinar a dose econômica de adubação nitrogenada para o milho em quatro épocas de cultivo. O experimento foi conduzido em delineamento em blocos casualizados, em esquema de parcelas subdividas, com quatro repetições. As parcelas foram constituídas por quatro épocas de plantio (E1: 28/05, E2: 11/06, E3: 25/06 e E4: 22/07) e nas subparcelas foram aleatorizadas quatro doses de N (0, 75, 150 e 225 kg ha-1). A cultivar de milho foi a AG7088, sendo a produtividade medida na fase de grão farináceo. A produtividade agrícola foi de 8,0; 7,5; 5,9 e 6,3 t ha-1 em E1, E2, E3 e E4, respectivamente. A resposta do milho ao N foi significativa, em que a dose de 225 kg ha-1 de N proporcionou média de 4,0 t ha-1 a mais quando comparada ao cultivo sem adubação nitrogenada. Para o valor médio da saca de milho igual a R$ 30,00, a dose máxima econômica é 174, 163, 215 e 52 kg ha-1 de N para o plantio em 28/05, 11/06, 25/06 e 11/07 de 2014, respectivamente, e a dose econômica média é 151 kg ha-1.

Development of companies operating logistics service centres by employing the results of network research
Authors: Karmazin György , Ulechla Gergely
Published: August 2016

Logistics centres of huge capacity and having the ability to create added value have emerged in recent decades. These centres have become network nodes between the co-operating organizations which accomplish the management of supply chains (networks) by connecting different modalities and networks with their infrastructure and informatics. The effective operation of logistics centres presented in business networks are usually managed by logistics supplier businesses (3PL/4PL). Defining the supply net as a complex network, logistics centres may be called hubs, the routes and relationships connecting the centres or – by borrowing the term used in network theory – may be called edges. Hub management provides core supply chain execution and visibility. Taking into consideration earlier results of network research we are searching for correlations between its proven principles and the growth possibilities of the centres (hubs) operated by logistics service providers. In addition, the results concerning cell networks provide further, new insights and increasing opportunities to consider the logistics systems within the field of theoretical network science. The present paper has developed as a result of the logistics supplier companies’ strategic responses to the challenges of a rapidly changing environment, both on local and global level.

Published: August 2016

In developing countries, the impact of malaria on human health, productivity and human development is well profound. It possesses serious challenge to the survival of several vulnerable poor, whose livelihood depends solely on agriculture. This study was carried out to examine the impact of malaria on the productivity of arable crop farmers and further estimate the cost implication of malaria (direct and Indirect) in rural Nigeria. Data were collected from a random sample of 91 crop farmers through the use of a well- structured questionnaire. The data were analyzed using descriptive statistics and multiple linear regression. The mean age of the crop farmers was 48 years with only 87.9% percent headed by males. The household heads are largely had primary education. Specifically malaria prevalence, household size, farming experience and cost of malaria treatment were significant factors that influenced crop productivity in the study area. It recommended that public enlightenment under the aegis of the “Roll Back Malaria Campaign” should be intensified and treated mosquito bed nets should be provided at subsidized rates to arable crop farmers. Farmers on their part should keep clean environment. Due regard should be given to environmental sanitation in the rural farming communities in the state.

Por uma sociologia da alteridade: ética e diálogo na ação pública em unidades de conservação
Authors: De Nazaré Lameira Rosa Benilde , Bittencourt da Silva José
Published: August 2016

A presente discussão trata das relações sociais entre os agentes gestores da política ambiental de UC e os usuários da Resex Marinha de Soure localizada na Ilha de Marajó, no estado do Pará. Ao tratar dessas interações observam-se as assimetrias e a sobreposição de interesses, princípios e valores reafirmados pelo modus operandi estatal. Aponta-se como condição imprescindível de ser observada nesse processo de interação a existência de ethos ambientais locais. As Reservas Extrativistas (RESEX), enquanto instituição política, instituem novas formas de se relacionar com a natureza, estabelecendo um estranhamento por parte da população, que vê seu lugar de vida e trabalho regido por regras que não estão claras para as pessoas, principalmente por não verem ali reconhecidos seus modos de ser e fazer locais. A metodologia adotada para a coleta de dados visando perceber para além das estruturas objetivas, particularmente as percepções dos agentes sociais envolvidos na políticade UC, considerou o uso de técnicas que permitiram uma aproximação qualitativa na busca dos sentidos atribuídos pelos agentes às suas ações, tecendo suas conexões e desdobramentos. Foram usadas entrevistas, conversas informais, análises documentais e observação direta.
“Grandes empreendimentos”, pertencimento local e gestão de acesso ao trabalho
Authors: Otavio Bezerra Marcos
Published: August 2016

A construção de “grandes empreendimentos” econômicos tem desencadeado transformações significativas nas relações sociais em localidades nas quais são instalados. Uma dimensão dessas transformações diz respeito à importância que os responsáveis pelos empreendimentos passam a ter na gestão de práticas econômicas, políticas e administrativas e na difusão de novos modos de percepção sobre estas práticas. O presente trabalho examina de que maneira critérios de pertencimento local são utilizados – corroborando representações sobre a distinção entre trabalhadores “locais” e “de fora” – como mecanismos de seleção de candidatos a postos de trabalho criados pela obra de construção do Complexo Petroquímico do Rio de Janeiro (COMPERJ), projeto administrado pela Petrobras e em execução no município de Itaboraí (RJ). A análise das discussões públicas e medidas administrativas adotadas com vistas à regulação do mercado de trabalho é o caminho analítico aqui escolhido para demonstrar como esses empreendimentos constituem uma nova fonte de poder nas localidades e, por conseguinte, intervêm no modo de governo do território e das populações por eles abrangido.
Onde a comida não tem gosto: uma análise do gosto como prática e interação
Authors: De Assunção Viviane Kraieski
Published: August 2016

Este artigo baseia-se em dados de uma pesquisa etnográfica sobre as práticas alimentares de imigrantes brasileiros na Grande Boston, e discute as afirmações recorrentes dos sujeitos de pesquisa de que a comida nos Estados Unidos “não tem gosto”, mas que é possível “se acostumar” a ela. Nesse sentido, discute o que é gosto, a partir da literatura socioantropológica, e propõe duas abordagens interpretativas: o gosto é entendido (1) enquanto prática, contemplando a dinamicidade das ações dos interlocutores em seu cotidiano, e (2) como elemento constituinte das interações sociais dos sujeitos da pesquisa. Dessa forma, o artigo conclui que o gosto, em sua dimensão sensorial, é parte das estratégias que os sujeitos utilizam para viver no contexto migratório, lidar com as dificuldades nos Estados Unidos e manter laços com familiares, parentes e amigos que permaneceram no Brasil.

A Fittel e o “Novo Sindicalismo” - 1985-1997
Authors: Souto Fernando
Published: August 2016

Este trabalho pretende discutir dois pontos relacionados à Federação Interestadual dos Trabalhadores em Empresas de Telecomunicações (Fittel). Em primeiro lugar, dentro do que se convencionou chamar de “novo sindicalismo”, durante os anos 1980 e 1990, não se deu visibilidade às organizações sindicais criadas e mantidas fora da zona de controle da estrutura sindical. Em segundo lugar, a manutenção de projetos como esse revela os ideais e as contradições baseadas num projeto que se pensou fora da estrutura sindical e que nasceu no berço do “novo sindicalismo”. Esse foi o caso da Fittel. O que se pretende mostrar é a dificuldade de manutenção de uma organização sindical como essa com inúmeros conflitos que revelam a diversidade de projetos em disputa para os trabalhadores telefônicos. Este artigo é parte da tese de doutorado do pesquisador, um trabalho com metodologia qualitativa, entrevistas semiestruturadas e pesquisa documental em jornais sindicais, jornais diários, documentos produzidos pelos sindicatos, entre outros.
Nas fronteiras do Estado-nação: conflitos socioambientais e incêndios florestais nas terras indígenas dos Awá-Guajá no Maranhão

As situações de conflitos socioambientais, experienciadapor esse grupo indígena, são indicativas de um processo de territorialização produzido pela pressão de interesses econômicos, conjugados às políticas desenvolvimentistas executadas por programas de governo. Trata-se de novo tipo de genocídio doméstico, no qual se incluem formas de genocídio cultural,perpetradas contra grupos de caçadores e coletores ameaçados de extinção, como os Awá-Guajá, vítimas de uma economia de desenvolvimento predatório.
A BLUEPRINT FOR INDIA’S ECONOMIC FUTURE A Method to Address Economic Recession, Remove Poverty, Terrorism, Improve Law and Order, Reduce Drug Abuse, Inflation and Taxes in an Interest Free Based Economy
Authors: Khan Niaz Ahmed
Published: August 2016

I have developed a new financial instrument which will be much more valuable than the bonds or the treasury bills government sold in the open market to raise much needed funds to run the country. These are all interest based instruments and can only be used by institutions. The instrument I am proposing is without interest and will be used by everybody to purchase goods and services in the government and the private sector resulting in up to 66% discounts. This is why these will be massively bought up front in large amounts in the shortest period of time of one month to run the country for at least a year and much more by the end of the year.
Dynamic synergy analysis in international business: the concept and application to two players China and Russia
Authors: Namaki M S S El
Published: August 2016

There are two ways to conduct economic, and possibly political, business between countries. The first is conventional search for country present day competitive advantage (Porter, 1990). Yet competitive advantage is transient, not sustainable (Forbes, 2.6.2013). And competitive advantage could relate to yesterday’s industries not today’s arenas. A more plausible search is that for strategic synergy or a situation where the two countries whole is greater than the sum of individual country parts. The later, the synergy route, places emphasis on strategic longer term complementarity or synergy between the two countries rather than a transient advantage.

 

The following article addresses the second scenario.

It projects a model for the identification of the term driving forces of two economies, tracing their respective future synergies and deriving synergy-rooted strategies. The article goes on to apply the model to two countries: China and Russia, being contemporary illustrations of a largely politically driven search for economic synergy.

The model could have conceptual as well as applied dimensions. Conceptually, it provides a theoretical framework for present day international business concepts. Operationally it could lead to specific strategies, and venues, for economic and business engagement between countries.
Paradoxical Authorship: Tracing Authority in the Gorakhbāṇī
Authors: Marrewa Karwoski Christine
Published: August 2016

¿Cómo podemos entender a un autor que pudo o no haber existido hace cientos de años, pero que resulta crucial para la comprensión de un texto? Se cree que el Gorakhbāṇī, un texto filosófico que contiene las enseñanzas del yogui Gorakh, fue compuesto en algún momento del siglo XVII. Entre otras cosas, el texto hace hincapié en la necesidad de un maestro o gurú para comprender el verdadero significado: “La palabra verdadera constituye un cálculo de oro. Quien carece de maestro es un impostor, el discípulo de un gurú permanece virtuoso. Quien deambula sin maestro cae en el vicio” (Barthwal, Gorakh-Bānī, 149).Sin embargo, el gurú al que se refiere este texto es el asceta indio semi legendario Guru Gorakhnāth, quien se cree que vivió cientos de años antes de la composición del texto. Esta problemática ocasiona dificultades específicas al tratar la cuestión de la autoría de este texto premoderno. En este ensayo, mi argumento es que es necesario concebir a este guru como el autor del texto. Mientras que su existencia es fundamental para comprender la veracidad del texto, al mismo tiempo él resulta necesariamente inexistente. Recurriendo a las teorías de Roland Barthes y Michel Foucault, el objetivo es sugerir que la autoría del Gorakhbāṇī debe entenderse según su propio y paradójico rubro.
Capacidad y modalidad. Una discusión de Aristóteles, Metafísica 1047a24-29 y 1048a11-16
Authors: Salles Ricardo
Published: August 2016

En este artículo, me ocupo de dos pasajes de Aristóteles en los primeros cinco capítulos de Metafísica Θ estrechamente ligados entre sí (1047a24-29 y 1048a11-16). Intento mostrar, a través de ellos, que para Aristóteles podemos ser capaces de llevar a cabo una acción que resulta ser imposible en una situación dada. Esta tesis complementa otra igualmente importante, según la cual puede ser posible que realicemos una acción que, sin embargo, somos incapaces de realizar. Ambas tesis revelan que para Aristóteles los conceptos de capacidad y posibilidad en los primeros cinco capítulos de Metafísica Θ son independientes entre sí. Pero si bien la segunda tesis ha sido objeto de estudio en el reciente comentario de Stephen Makin al libro Θ, la primera tesis no ha recibido toda la atención que merece.
Virtudes públicas en las inscripciones funerarias latinas: la expresión de la fortaleza y elocuencia femeninas
Authors: Muñoz García de Iturrospe María Teresa
Published: August 2016

Los epitafios latinos dedicados a mujeres de toda condición encomian con frecuencia las virtudes de la puella y de la matrona ejemplar, eminentemente domésticas. Sin embargo, valores considerados masculinos como la fortaleza, la justicia y la elocuencia son ocasionalmente subrayados en inscripciones tanto métricas como en prosa, con una finalidad fundamentalmente consoladora que, sobre todo en las inscripciones cristianas, sirve además para completar un nuevo modelo de comportamiento.

Consideraciones acerca de los conceptos de función y atelesis al tenor de la filosofía de la ciencia.
Authors: De León Ovidio
Published: August 2016

En el presente trabajo se discuten los conceptos de función y de atelesis que Honorio Delgado utilizó para fundamentarsu teoría en torno a la psicopatología esencial de la esquizofrenia. Se revisan someramente primero los conceptosbiológico-filosóficos del término función, y se presentan luego algunas consideraciones epistemológicas a fin dedemostrar que la concepción Delgadiana de atelesis permite la formalización de un sistema natural. Se discute luegocómo la medición de términos hipotéticos, que no se basan en la observación, puede conducir a la validación de unateoría. Esta explicación permite apreciar que la atelesis, en tanto que organización trascendental, es susceptible deser analizada desde el punto de vista lógico-matemático con el objeto de vincular sus elementos, determinar suespecialización dentro del sistema de la personalidad, y esclarecer las relaciones entre la teoría y la realidad clínicade la esquizofrenia.(Rev Neuropsiquiatr 2009; 72:17-24).

This study investigated the neuroprotective effects of methyl 3,4-dihydroxybenzoate (MDHB) against t-butylhydroperoxide(TBHP) induced oxidative damage in SH-SY5Y (human neuroblastoma cells) and the underlying mechanisms. SH-SY5Y were cultured in DMEM+10% FBS for 24 hours and pretreated with different concentrations of MDHB or N-acetyl-L-cysteine (NAC) for 4 hours prior to the addition of 40 μM TBHP for 24 hours. Cell viability was analyzed using the methyl thiazolyl tetrazolium (MTT) and lactate dehydrogenase (LDH) assays. An annexin V-FITC assay was used to detect cell apoptosis rate. The 2',7'-dichlorofluorescin diacetate (DCFH-DA) assay was used to determine intracellular ROS levels. The activities of antioxidative enzymes (GSH-Px and SOD) were measured using commercially available kits. The oxidative DNA damage marker 8-OHdG was detected using ELISA. Western blotting was used to determine the expression of Bcl-2, Bax, caspase 3, p-Akt and Akt proteins in treated SH-SY5Y cells. Our results showed that MDHB is an effective neuroprotective compound that can mitigate oxidative stress and inhibit apoptosis in SH-SY5Y cells
Design and Optimization of an Efficient (96.1%) and Compact (2 kW/dm3) Bidirectional Isolated Single-Phase Dual Active Bridge Ac–Dc Converter
Authors: Everts Jordi
Published: August 2016

The growing attention for plug-in electric vehicles, and the associated high-performance demands, have initiated a development trend towards highly efficient and compact on-board battery chargers. These isolated ac-dc converters are most commonly realized using two conversion stages, combining a non-isolated power factor correction (PFC) rectifier with an isolated dc-dc converter. This, however, involves two loss stages and a relatively high component count, limiting the achievable efficiency and power density and resulting in high costs. In this paper a single-stage converter approach is analyzed to realize a single-phase ac-dc converter, combining all functionalities into one conversion stage and thus enabling a cost-effective efficiency and power density increase. The converter topology consists of a quasi-lossless synchronous rectifier followed by an isolated dual active bridge (DAB) dc-dc converter, putting a small filter capacitor in between. To show the performance potential of this bidirectional, isolated ac-dc converter, a comprehensive design procedure and multi-objective optimization with respect to efficiency and power density is presented, using detailed loss and volume models. The models and procedures are verified by a 3.7 kW hardware demonstrator, interfacing a 400 V dc-bus with the single-phase 230 V, 50 Hz utility grid. Measurement results indicate a state-of-the-art efficiency of 96.1% and power density of 2.2 kW/dm3, confirming the competitiveness of the investigated single-stage DAB ac-dc converter.

The aim of this research was to isolate and indentify the terpenoid compound from Curcuma xanthorrhiza rhizomes and its antibacterial activity. Isolation was carried out by using vacuum liquid chromatography and centrifugal chromatography. The structure was determined by NMR spectroscopy (1H-NMR, 13C-NMR 1D and 2D), then compare with data from literatures. Antibacterial test was carried out by using  microdillution methods and evaluated against eight bacteria. They are Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Enterobacter aerogenes, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysentriae and Vibrio cholerae. The result showed that the isolate was a white crystal which was indetified as germacron-type sesquiterpene. Germacron have highest activity againts P. aeruginosa, MIC 15.6 µg/mL and MBC 31.2 µg/mL.
Magnetic Resonance Imaging of Articular Cartilage
Authors: Ashraf Shaafiya , Zahoor Adnan
Published: August 2016

➢ The emergence of newer pharmacotherapeutic agents and surgical cartilage resurfacing techniques is driving the need for imaging modalities capable of early, accurate, and reproducible lesion detection.

➢ Magnetic resonance imaging (MRI) has emerged as a noninvasive tool for direct 2-dimensional (2D) and 3-dimensional (3D) assessment of the articular cartilage in both clinical and research settings. MRI has largely overcome the shortcomings of the current gold standard, radiography, by allowing for the detection of preclinical disease and subtle early abnormalities prior to the onset of radiographic disease, when damage is still reversible.

➢ Current MRI techniques are either morphological (2D/3D qualitative and quantitative techniques) or compositional (matrix-assessment techniques that detect macromolecular changes prior to morphological changes).

➢ MRI is evolving as a complete answer to our cartilage-imaging requirements of lesion description, treatment planning, and outcome measurement as well as in various research settings.
Correction of Atmospheric Haze of IRS-1C LISS-III Multispectral Satellite Imagery: An Empirical and Semi-Empirical Based Approach
Authors: Mustak Sheikh , Baghmar Naresh , Singh2 Sudhir
Published: August 2016

The atmospheric effect greatly affects the quality of satellite data and mostly found in the polluted urban area in the great extent. In this paper, the atmospheric correction has been carried out on IRS-1C LISS-III multispectral satellite image for efficient results for the Raipur city, India. The atmospheric conditions during satellite data acquisition was very clear hence very clear relative scattering model of improved dark object subtraction method for the correction of atmospheric effects in the data has been carried out to produce the realistic results. The haze values (HV) for green band (band 2), red band (band 3), NIR band (band 4) and SWIR (band 5) are 79, 53, 54 and 124, respectively; were used for the corrections of haze effects using simple dark object subtraction method (SDOS). But the final predicted haze value (FPHV) for these bands are 79, 49.85, 21.31 and 0.13 that were used for the corrections of haze effects applying improved dark object subtraction method (IDOS). We found that IDOS method produces very realistic results when compared with SDOS method for urban land use mapping and change detection analysis. Consequently, ATCOR2 model provides better results when compared with SDOS and IDOS in the study.

Wstęp: Choroby narządów zmysłów są poważnym problemem badawczym oraz społecznym. Schorzenia wywołujące ślepotę stanowią znaczny odsetek wśród tych, które zdecydowanie obniżają jakość życia pacjenta, dlatego należy próbować zrozumieć mechanizmy będące źródłem problemu, a następnie znaleźć metodę leczenia, która go wyeliminuje. Wykorzystuje się do tego celu zwierzęta, u których występuje określona mutacja genetyczna będąca przyczyną choroby. W niniejszej pracy oceniono doświadczalnie model powolnej degeneracji siatkówki.Materiał i metody: Do badań wykorzystano homozygotyczne myszy pod względem mutacji w genie PRPH2 oraz osobniki heterozygotyczne uzyskane poprzez skrzyżowanie homozygot z myszami BALB/c. Określono postęp zmian degeneracyjnych w czasie za pomocą pomiarów grubości poszczególnych warstw siatkówki w kolejnych punktach czasowych. Do oceny nabłonka barwnikowego użyto barwienia immunofluorescencyjnego preparatów Flat Mount z wykorzystaniem przeciwciała anty-RPE65. Funkcję bioelektryczną siatkówki oszacowano za pomocą elektroretinografii zarówno w adaptacji nocnej, jak i dziennej w comiesięcznych badaniach.Wnioski: Analizując uzyskane dane, zauważono, że zmiany zwyrodnieniowe u homozygot wywołały całkowitą atrofię zewnętrznych oraz wewnętrznych odcinków komórek receptorowych, warstwy jądrzastej zewnętrznej, a także splotowatej zewnętrznej. Badanie ERG wykazało całkowite wygaszenie aktywności siatkówki już od 1. miesiąca życia. W przypadku heterozygot kinetyka zmian była znacznie wolniejsza. W przeciwieństwie do homozygot nie zaobserwowano całkowitej atrofii żadnej warstwy siatkówki. Elektroretinografia wykazała stopniowy zanik funkcji bioelektrycznej siatkówki do 15. miesiąca życia.
