Índice de calor e desconforto térmico humano nas condições de ambiente natural em Patos, PB, Brasil
Get PDFMonografiaThe urban climate in the same way that the interior of the constructions, exercises influence in
the man's thermal comfort. In open spaces, the human comfort can be affected by several parameters, among them the climatic ones, the human activities and many studies of thermal comfort are accomplished in internal atmospheres, mainly elaborated by architects, the criteria and the approach used to evaluate the comfort conditions in external atmospheres cannot be the same ones that in internal conditions. The present work had as objective analyzes the Indexes of Heat and Thermal Discomfort, located in the Patos-PB. For the present work, monthly data were analyzed among the years of 2008 and 2018. they were used the software R, with that, we conclude that, the hottest years were 2012 and 2013 with averages of around 35,3 °C, the year with more suave temperature was in 2011 with temperature of 33,77 °C. The average of relative humidity more discharge was in 2009 with percentile of 68,67% and lower average in 2015 and 2017 with 54,23%. The presents data were necessary to make the calculations of the indexes (IDT and IC), such indexes moderate levels of classifications and in agreement with the analyses IDT had maxim and larger lows than 26,5 °C, consisting like this, classification as uncomfortable. Regarding IC he/she had averages between 54,3 °C and 48,23 °C, ending that for levels above 54 °C, it is classified with the level of end danger, taking risk of Cerebral Vascular Accident imminent, and among 41-54 °C it is considered in danger with risks of cramps and heatstroke.O clima urbano da mesma forma que o interior das edificações, exerce influência no conforto térmico do homem. Em espaços abertos, o conforto humano pode ser afetado por diversos parâmetros, entre eles os climáticos, as atividades humanas e muitos estudos de conforto térmico são realizados em ambientes internos, principalmente elaborados por arquitetos, os critérios e a abordagem utilizada para avaliar as condições de conforto em ambientes externos não podem ser as mesmas
que em condições internas. O presente trabalho teve como objetivo analisar os Índices de Calor e Desconforto Térmico, localizado na cidade de Patos-PB. Para o presente trabalho, foram analisados dados mensais entre os anos de 2008 e 2018. Foram usados o software R, com isso, concluirmos que, os anos mais quentes foram 2012 e 2013 com médias de em torno de 35,3 °C, o ano com temperatura mais amena foi em 2011 com temperatura de 33,77 °C. A média de umidade relativa mais
alta foi em 2009 com percentual de 68,67% e média mais baixa em 2015 e 2017 com 54,23%. Os presentes dados foram necessários para efetuar os cálculos dos índices (IDT e IC), tais índices reportam níveis de classificações e de acordo com as análises o IDT teve máxima e mínimas maiores que 26,5 °C, constando assim, classificação como desconfortável. Com relação ao IC teve médias entre 54,3 °C e 48,23 °C, concluindo que para níveis acima de 54 °C, é classificado com o nível de
extremo perigo, correndo risco de Acidente Vascular Cerebral iminente, e entre 41- 54 °C é considerado em perigo com riscos de câimbras e insolação.Trabalho não financiado por agência de fomento, ou autofinanciad
Projeto e análise de desempenho de uma câmara frigorífica: a aplicação em um supermercado na cidade de Pombal - PB
Get PDFO ato de remoção do calor de um ambiente é chamado de refrigeração, onde, nesse procedimento o objetivo é reduzir a temperatura e conservar umidade. A conservação de alimentos por meio da estocagem em um local que possua temperatura e umidade controlada teve um salto imenso desde a criação de máquinas para fabricação de gelo artificial, até a instalação de câmaras frigoríficas comerciais, essa, denominada como qualquer espaço de armazenamento em que as suas condições internas permaneçam controladas através de um sistema de refrigeração. Para o presente trabalho, o objetivo foi realizar o dimensionamento para uma posterior construção de uma câmara em um supermercado na cidade de Pombal, Paraíba, com foco no armazenamento de produtos de origem animal. Foi feito a coleta das dimensões do local, para executar o desenho em 3D, bem como, aplicação de cálculos de: carga térmica, coeficiente de desempenho e perda de pressão do sistema. Com os resultados obtidos nos programas e mediante catálogos disponibilizados por fornecedores, foram selecionados o material isolante e os componentes principais do sistema. Por fim, foi disponibilizada uma tabela com os custos dos materiais previamente escolhidos para ser entregue ao dono do estabelecimento para posterior execução.55 p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
