Préstamos Arawak (Achagua, Piapoco y Piapoco-Achagua) a la lengua sikuani
Authors: Meléndez Lozano Miguel Ángel
Published: April 2017

El artículo está centrado en los préstamos arawak (achagua y piapoco) a la lengua sikuani (guahibo).  Combina análisis lingüístico y análisis histórico para dilucidar direcciones e influencias de los préstamos de las dos lenguas arawak hacia el sikuani y, por extensión, a otras lenguas guahibo.  Desde el siglo XVIII hasta el siglo XX dos planteamientos han considerado al sikuani (conocido anteriormente como guahibo) como  lengua arawak o como lengua perteneciente a una familia independiente (guahibo).  La opinión de más consenso es la última.  La presencia lingüística arawak en sikuani ha sido muy fragmentariamente ilustrada. Con 213 expresiones mostradas en este artículo (además del análisis) se aporta a una nueva dimensión: los préstamos lingüísticos en la Orinoquia colombo-venezolana de las lenguas arawak achagua y piapoco sobre la lengua sikuani (guahibo).
Modelagem e animação para análise de espaços em projetos não construídos
Authors: Florio Wilson , Tagliari Ana
Published: April 2017

Esta pesquisa, realizada entre os anos de 2012 e 2015, investigou doze projetos não construídos do arquiteto Vilanova Artigas por meio de modelagem paramétrica e animação. A análise a partir da animação permitiu visualizar a conexão espacial entre diferentes ambientes durante o percurso virtual. Neste texto o foco reside nos procedimentos metodológicos adotados para a análise dos espaços dos projetos selecionados. O artigo está estruturado em três tópicos. O primeiro pormenoriza o critério de seleção dos projetos, assim como os procedimentos metodológicos relativos à modelagem geométrica e paramétrica, com o auxílio do Rhinoceros e do Grasshopper. No segundo tópico são explicitados os conceitos sobre os tipos de simulações, as subetapas do processo de simulação de espaços internos no programa 3D Max, bem como a produção das animações. No terceiro tópico é realizada uma discussão sobre as dificuldades e descobertas inesperadas ocorridas durante a investigação, e os resultados obtidos. A contribuição original do artigo reside na investigação de projetos pouco estudados, assim como os procedimentos metodológicos de análise de espaços internos, que envolvem a interpretação por desenhos e simulações amparados pelas novas tecnologias digitais.
BIM na avaliação do ciclo de vida de edificações: revisão da literatura e estudo comparativo
Authors: Barros Natalia Nakamura , Silva Vanessa Gomes da
Published: April 2017

A necessidade da redução do consumo de energia elétrica e de emissão de GHGs (GreenHouse Gases) já é consensual. Sabe-se que edifícios consomem quantidades significativas de energia, além de emitirem grandes quantidades de GHGs. Devido a essa enorme influência sobre a sociedade, é fundamental para arquitetura e construção estar consciente do seu impacto, e desenvolver ferramentas eficazes que são capazes de medir a origem e a possível redução destes impactos, com o uso da avaliação do ciclo de vida de edificações (ACV) aliada ao Building Information Modeling (BIM). Este artigo fornece uma contribuição teórica no campo de integração de BIM e avaliação de ciclo de vida (ACV). A revisão de literatura evidencia que as publicações no tema BIM/ACV concentram-se no desenvolvimento e no melhoramento das ferramentas computacionais para auxiliar a ACV nas fases de projeto e de construção de edificações. São poucas as contribuições que tratam do processo de trabalho. Para contribuir no preenchimento desta lacuna de conhecimento, este artigo analisa o impacto potencial trazido pela adoção de BIM na ACV da perspectiva de processo, tecnologia associada e informação trocada. O método compõe-se de uma revisão sistemática de literatura (RSL), seguida da análise de fluxos de trabalho de avaliação tradicional de energia e emissão de GHGs incorporadas no ciclo de vida comparativamente ao fluxo de trabalho mediado por BIM. A RSL identificou lacunas e tendências de pesquisa, e embasou a elaboração de fluxos de trabalho analisados. Da análise comparativa depreendeu-se que a adoção de BIM no fluxo de trabalho de avaliação de energia incorporada e emissão de GHGs no ciclo de vida de edificações, tem impacto variado no processo de projeto e alto impacto na coleta de dados. A principal vantagem do uso de BIM na ACV é a sua capacidade de otimizar o processo, auxiliar a tomada de decisão durante toda a evolução do projeto e instigar a convergência para uma solução otimizada.
Jardins verticais: modelos e técnicas
Authors: Barbosa Murilo Cruciol , Fontes Maria Solange Gurgel de Castro
Published: April 2017

O presente artigo objetiva descrever e sistematizar as principais tecnologias existentes para sistemas de jardins verticais e discutir os benefícios da sua implantação na escala da edificação. A metodologia consiste em uma revisão bibliográfica e busca por patentes e produtos disponíveis no mercado, que ajudam a entender quais são os modelos existentes, como eles funcionam e suas vantagens e desvantagens. A revisão evidencia que os sistemas de jardins verticais surgem como estruturas possíveis de plantio em superfícies verticalizadas, contudo, o sucesso destes não apenas está relacionado com a escolha adequada da tecnologia de suporte, mas também do sistema de irrigação, da utilização de espécies adequadas ao clima e ao tempo de exposição à radiação solar. Ao discutir essas questões, o artigo objetiva, ainda, contribuir para a difusão do conhecimento dessa importante tipologia da infraestrutura verde.
Espaços livres, padrões morfológicos e apropriações públicas na metrópole paulistana
Authors: Queiroga Eugenio Fernandes
Published: April 2017

A morfologia da metrópole paulistana é o resultado de relações complexas entre processos sociais e o suporte biofísico, apresentando qualidades e desafios inerentes a seu porte (uma das quatro maiores metrópoles do planeta) e a sua inserção na formação socioespacial brasileira. Neste contexto objetiva-se compreender aspectos de sua estrutura morfológica e de seu sistema de espaços livres. A partir de análise visual de imagens de satélite, bem como do uso do aplicativo Google Street View, o Laboratório Quadro do Paisagismo da Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo – Lab QUAPÁ - produziu minuciosa cartografia temática em SIG sobre padrões morfológicos e espaços livres, quadra a quadra, para toda a área conurbada da Região Metropolitana de São Paulo. A análise dessa cartografia temática é apoiada também em dados censitários cartografizados e em amplo acervo de fotos realizadas a partir de sobrevoos sobre a metrópole. Esse artigo traz uma síntese dos principais resultados obtidos, com ênfase no sistema de espaços livres, abordando também reflexões relativas à apropriação pública deste sistema, decorrentes da experiência de orientação de diversos trabalhos científicos de graduação e pós-graduação. Tem-se um quadro que mostra uma metrópole fortemente conurbada, densamente construída, mas ainda apresentando notável predominância de morfologias horizontais. O sistema de espaços livres da metrópole paulistana contém significativos remanescentes de Mata Atlântica, mas apresenta-se, via de regra, pouco competente para o atendimento das diversas demandas sociais e ambientais.

Published: April 2017

Sabe-se que a altura dos edifícios da vizinhança, a relação dos espaçamentos entre as edificações e a largura das vias têm influência na absorção de radiação solar direta, no sombreamento das edificações e no consumo de energia nas edificações. Assim, este estudo tem por objetivo avaliar a influência do sombreamento do entorno em uma edificação unifamiliar com elevado isolamento térmico localizada na ZBB 2. O método utilizado nesse trabalho consiste na simulação computacional de edificação com diferentes configurações de entorno, dividindo-se em 5 etapas: definição da hipótese de pesquisa; simulação do nível de eficiência energética considerando o RTQ-R; modelagem do entorno e análise do rastreamento de sombras; simulação do desempenho energético e do nível de conforto térmico; e análise dos resultados. Foram modeladas oito diferentes possibilidades de sombreamento. A configuração que apresentou o menor consumo energético e maior nível de conforto térmico foi a edificação sombreada pelo entorno de 6 pavimentos, com consumo de climatização de 26,44 kWh/m².ano e índice de conforto térmico de 97,72%. Os resultados indicaram que o elevado nível de isolamento térmico de uma edificação gera um melhor desempenho termoenergético do envelope, mesmo com o sombreamento de paredes no período de inverno.

Published: April 2017

Produtos habitacionais residenciais para venda são desenvolvidos em um ambientes não colaborativos, caracterizados por relações de adversidade. Estes elementos, somados às restrições orçamentárias presentes, frequentemente geram produtos onde estas restrições acabam reduzindo atributos de valor na perspectiva de clientes e usuários finais. Neste sentido, novas abordagens como o Target Value Design (TVD), podem representar alternativas para uma gestão do processo de projeto, na qual a perspectiva de valor do cliente é o ponto focal para o desenvolvimento do produto. Entretanto, é grande a resistência do setor na adoção de novas abordagens gerenciais. Assim, as simulações representam uma forma de apresentar novos conceitos e inovações em ambientes resistentes à mudança, por serem uma condição livre de riscos. Nesse sentido, o Marshmallow Game tem sido utilizado como um referencial de simulação para se vivenciar os conceitos do TVD, estabelecendo um padrão de comparação com o processo tradicional de gestão de projetos. Ainda assim, esta comparação tem sido dificultada nas suas versões precedentes, pela falta de evidências concretas para este fim. Esta pesquisa propõe melhorias para o uso do Marshmallow Game como ambiente de simulação do processo tradicional e do TVD e adota a Design Science Research (DSR) como estratégia de pesquisa. Assim, conduziu-se uma instanciação para promover modificações e melhorias na simulação previamente existente. Como resultado, além de propor estas adaptações, o artigo traz novos elementos assertivos para propiciar uma comparação conceitual e prática entre o processo tradicional e o TVD.

Anomaly Detection on Gas Turbine Fuel System Using a Sequential Symbolic Method
Authors: Li Fei , Wang Hongzhi , Zhou Guowen , Yu Daren , Li Jianzhong , Gao Hong
Published: April 2017

Anomaly detection plays a significant role in helping gas turbines run reliably and economically. Considering collective anomalous data and both sensitivity and robustness of the anomaly detection model, a sequential symbolic anomaly detection method is proposed and applied to the gas turbine fuel system. A structural Finite State Machine is to evaluate posterior probabilities of observing symbolic sequences and most probable state sequences they may locate. Hence an estimating based model and a decoding based model are used to identify anomalies in two different ways. Experimental results indicates that these two models have both ideal performance overall, and estimating based model has a strong ability in robustness, while decoding based model has a strong ability in accuracy, particularly in a certain range of length of sequence. Therefore, the proposed method can well facilitate existing symbolic dynamic analysis based anomaly detection methods especially in gas turbine domain.
Oxide Self-Flux in Optical Floating Zone Crystal Growth of Nickel Niobate (NiNb2O6)
Authors: Munsie Timothy J. S. , Millington Anna , Luke Graeme M. , Dabkowska Hanna A.
Published: April 2017

Growing crystals of nickel niobate (NiNb2O6), we noticed that changing growth conditions allowed our material to enter different areas of the phase diagram. In particular, we found that excess material accumulated within and above the liquid zone. Analysis showed that this was an unincorporated constituent. Changing the ratio of the constituent oxides - an excess of ~4% of either NiO or Nb2O5 gave us the opportunity to investigate changes in zone stability, melting temperature and quality of the resulting crystal. We found that a small excess of nickel oxide decreases the melting temperature significantly, and created the best pseudo-rutile NiNb2O6 crystal studied, while higher amounts of niobium oxide allowed us to stabilize the NiNb2O6 columbite phase. This research reinforces the idea that self-flux as a travelling solvent can significantly impact crystal growth parameters and quality.

Authors: Dluholucký Svetozár , Knapková Mária
Published: April 2017

Authors present The First Results of the National Extended Newborn Screening (ENS) in Slovakia in the majority (M) and the Roma (R ) ethnic populations. The follow-up of the ethnicity has been introduced in Newborn Screening for Cystic Fibrosis (NSCF) and after to entire ENS program comprising of 23 Hereditary Metabolic Disorders (HMD). Results: In 2013-2015, a total of 165,648 newborns were investigated in ENS, 23,321 of them (15,3%) were the R ethnic group, a total of 313 positive cases were discovered (total ENS prevalence = 1:529, M=1:758, R=1:198). In the R ethnic group, there was slightly higher prevalence in cong. hypothyreosis (CH), only one case of CF, and no cases of CAH in the R ethnic group. The ENS prevalence of HMD detected by MS/MS was expressively higher in the R ethnic group than in M group (M=1:1670 vs. R=1:234, OR:7,13). Significant differences in the prevalence of individual types of HMD were found. Whereas the PKU and spectrum of aminoaciduria and organic acidurias dominate in the M group, the fatty acids oxidation disorders (MCAD, SCAD) and carnitine defects (CUD) were frequent in the R newborn group. Conclusion: Despite the presented results are preliminary, the ethnic approach to ENS is enabling the recording of the ethnic differences in the screening prevalence of individual disorders, which would be missing during unitary approach.

An Analysis of Experimental Data on Lost Circulation Problems While Drilling With Oil-Base Mud
Authors: Onyia E. C.
Published: April 2017

The problem of lost circulation while drilling with high density oil base muds, especially in the "Gulf Coast" type drilling environment, is a difficult and frustrating problem that has plagued the use of oil base muds in the drilling industry. It has been found that the problem seems to go away if the wells are drilled with water based mud systems. However, certain geological and drilling constraints such as high wellbore temperatures, high deviation directional drilling programs, and differential sticking problems preclude the use of water based muds in certain cases in these environments.

General observations in the field suggest that the lost circulation problem occurs while drilling with both diesel and mineral oil base muds, but. is less frequent with diesel systems and more prevalent at mud densities above 14 ppg. The problem also occurs in both permeable and impermeable lithologies.

To address this problem, a joint industry project was undertaken three years ago to determine the causes, mechanics and solutions to the lost circulation phenomenon. The experiment consisted of hydraulic fracturing tests in permeable and impermeable rocks using water, diesel, and mineral oil base muds with and without lost circulation materials.

This paper presents an interpretative analysis of the test data collected from the project and some insights into possible field applications of the results.

Application of phosphorus (P) fertilizers and animal manures to P‐rich soils due to the historic use of P inputs can lead to greater P losses. In these soils, we need to manage legacy and new inputs of P in a way that they do not lead to P loss. Studies were conducted to (i) determine the effect of soil type on P leaching and (ii) investigate if changes in dairy and poultry diets can lead to lower P in manures and loss when manures are land applied.

Community- Based Projects in Nigeria
Authors: Muhammad Zayyanu
Published: April 2017

Experiences in the application of the community-based model for improving the quality of life of poor communities have reported improvement regarding project performance. However, most studies placed emphasis on the overall performance determined at the general level. For this reason, the findings do not allow for an adequate understanding of the explanatory factors for the success or failure of the projects. This article investigates the explanatory factors that account for the success and failure of a community-based development initiative in kebbi-state, Nigeria, using a case study approach.2398-4279 © 2016.

The Feasibility and Necessity of a Revolution in Geriatric Medicine
Authors:   Italian Society for Evolutionary Biology, 14100 Asti, Italy, Libertini Giacinto ,   Department of Translational Medical Sciences, Federico II University, 80138 Naples, Italy
Published: April 2017

Currently, geriatric medicine consists mainly of palliative treatment of the disorders that characterize senile decay. This is perfectly compatible with the prevailing view that aging is the inevitable result of multiple degenerative processes that cannot be treated effectively as they are, in themselves, inevitable and irreversible. This interpretation of aging clashes with a mass of data and arguments that, conversely, indicate that aging is a specific physiological function, favoured by supra-individual natural selection, and is genetically determined and modulated. According to this concept, it is possible to modify, or even reverse, aging by influencing its primary mechanisms. This is diametrically opposed to the current interventions used in geriatric medicine, which act only on the effects of such mechanisms. The goal of complete control of the aging process may appear Utopian; however, it is quite rational and feasible if we consider the already proven reversibility of aging at the cellular level and in some in vivo models. The method of achieving this objective by no means is to counter the countless changes that characterize aging. On the contrary, the method is to control the telomere-subtelomere-telomerase system, which appears to be the general determining factor and regulator of aging. This system can apparently be controlled by modifying telomerase activity, or even, as suggested recently, in combination with techniques that alter telomere and subtelomere structure. In the first instance, these interventions must predominantly address the control of some manifestations of aging, such as Alzheimer’s disease, Parkinson’s disease and age-related macular degeneration, which are particularly devastating in terms of patient suffering and the associated economic burden. Effective treatments for these diseases represent a pivotal challenge facing a revolution in geriatric medicine, which is now both feasible and essential. The implications of such a revolution will lead to developments that will extend well beyond the boundaries of geriatric medicine.

Active Balancing of Super-Capacitors
Authors: Starodubtseva V A , Shklyaev M O
Published: April 2017

В данной статье рассматривается решение одной из проблем использования суперконденсаторов, в связи с которым их применение является затруднительным в настоящее время. Как известно, из-за низкого номинального напряжения суперконденсаторов использование происходит при их последовательном соединении. При производстве суперконденсаторов имеется некоторый разброс параметров по емкости. В связи с этим возникает проблема разной скорости заряда суперконденсаторов, а именно: возникает вероятность перезаряда суперконденсатора, что может вызвать его пробой. Появляется необходимость ограничения напряжения на суперконденсаторе при заряде. Для проверки теоретических сведений проведено моделирование заряда последовательно соединенных суперконденсаторов в программной среде Multisim. В статье рассматриваются ключевые этапы разработки схемы устройства для ограничения напряжения на суперконденсаторах, которая будет являться активной балансировкой. Содержится расчет основных параметров данной балансировки. Для подтверждения работоспособности предложенной схемы проведено моделирование последовательно соединенных суперконденсаторов с использованием разработанной активной балансировки. Описаны результаты проведенных моделирований. Для наглядного представления принципа работы активной балансировки при моделировании были дополнительно выведены осциллограммы напряжений внутренних узлов схемы. В качестве доказательства важности правильного расчета параметров схемы проведено моделирование с неверно выбранными параметрами активной балансировки. Проведены описание и анализ результатов данного моделирования. В заключение раскрывается эффективность решения проблемы заряда последовательно соединенных суперконденсаторов. Раскрывается вопрос надежности и энергоэффективности использования модулей суперконденсаторов. С помощью приведенной статьи раскрывается вопрос ускорения внедрения использования суперконденсаторов в качестве накопителей энергии.
