Análise do comportamento térmico de paredes de madeira

This study consists in the observation and evaluation of the thermal behavior and distribution of wood composite walls, MDF – Medium Density Fiberboard, HDF – High Density Fiberboard, OSB – Oriented Strand Board and EGP – Edge Glued Panel. This study had the objective to present the experimental thermal behavior and to verify which one fit the thermal comfort standards for human labor For this work, was developed a thermal chamber, with one interchangeable side, so the wall prototypes would fit for each experiment. We studied walls made of MDF, HDF, OSB and EGP, which one had its own distinct behavior due to the panel construction. The EGP wall had shown the most reliable material for this usage at high temperatures. With this work, it was demonstrated the importance of choice for the right material and construction method for wooden composite walls, because if they were scaled poorly, the people exposed to them would be uncomfortable by the proportionate environment, and the costs for a resizing would be too high

A cor do citrino: efeito de irradiação e tratamento térmico

Quartz crystals under natural or artificial irradiation can acquire dark shades and variations btween smoky, black and brown but when submitted at heat-treatment they can become greenish, yellowish or brownish, called citrine at gem shops. In this work a lot of samples was collected from different places in Brazil (Corinto - MG, Diamantina - MG, Sento Sé - BA and Santana do Araguaia – PA) and at first they were submitted at artificial irradiation resulting in dark colours. After that they were submitted at heat-treatment in differents temperatures and time of exposure to record when color change happened to light colours. It variated according to each origin, temperature, time of expousure and different aluminiun and other chemical elements content. Its was possible to define the ideal conditions to results better colours and related it with geology and chemical quartz composition.

Análise preliminar para a estimativa da perda de calor sensível de um fluido homogêneo térmico em um reservatório de geometria cilindrica

This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating

Técnicas associadas à biotecnologia da reprodução para minimizar os efeitos do estresse térmico e aumentar a fertilidade em vacas leiteiras de alta produção

The dairy sector has undergone considerable economic losses due to low fertility rates due to adverse effects of heat stress on reproduction of cows. Genetic selection for increased production, coupled with the expanding dairy to tropical areas of the planet, and global warming has further aggravated the problem of heat stress. The effects of heat stress are multifactorial and act directly or indirectly at various levels of reproductive tissues, resulting in low fertility of cows, which in practice, results in reduced reproductive efficiency in the property, reducing the producers’ profit. Some strategies related to breeding biotechnology such as fixed-time artificial insemination, embryo transfer and use of BST, can minimize these effects and improve the reproductive efficiency of the herd

Análise da percepção da variação do campo térmico na cidade de São Paulo-SP: o exemplo da subprefeitura Sé

This research aimed to analyze the spatial area for the design of the Heat Island of Subprefecture Sé, in São Paulo-SP, with the support of geotecnology and based on the study of environmental perception. We used remote sensing products such as maps ofland use and soil temperature and apparent surface to evaluate the thermal conditions considered critical points in the central area of the municipality. The methodology used was qualitative analysis, based on interviews with the people, allowing rescue geoecology the conditioning aspects of the city, with an emphasis on environmental perception. This study aimed toanalyze the perception of the variation of the thermal field in São Paulo. The results indicated that (95%) of respondents feel that the temperature of the central area has increased each year, and the district that stood out was the Sé, due to intense use and occupation of land and contribute one of the largest shopping centers. Districts with points given for having better thermal comfort were Santa Cecília, the República and Bela Vista, due to their larger amount of green areas by fiscal court, which act as local refrigerators. It was found that the respondents have the perception and awareness of their spa directly related to the quality of life. Through analysis of several variables involved, proposals and strategies may support public policies and urban planning

Influência de software de otimização de corte no rendimento de serraria da região sudoeste paulista

This study aimed to analyze the increase of yield provided by a software optimization cutting in a pine sawmill, located at southwest region of São Paulo, city of Itapeva. First were measured 10 logs that were processed by conventional sawing system by measuring the volume of products in the process output. Then using a cutting optimization software, that generated cuts diagrams, 10 logs, from 25 to 26 cm diametrical class, were processed by sawing system optimized. For the conventional sawing, the value found to yield was 41.80%, whereas for the unfolding optimized showed the value of 61.79%, resulting in a difference of 19.99%. This study shows that there is room for significant improvement of performance in sawmills sawing with the use of optimization software as the employee at work

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Direcionamento de peptídeos tolerogênicos da proteína de choque térmico 60 para células dendríticas utilizando anticorpos anti-DEC-205

A indução de tolerância imunológica em situações altamente desejadas como no transplante e em doenças autoimunes permanece um grande desafio para pesquisa científica de tradução. Nesse contexto, o estudo das proteínas do choque térmico (HSPs) e seus peptídeos vêm trazendo informações relevantes sobre o controle da reposta imune. Dados da literatura mostram que alguns de seus peptídeos apresentam propriedades imunorreguladoras, como os peptídeos N3 e N7 da HSP60. Além disso, tem se mostrado que a apresentação de antígenos em contextos específicos por células dendríticas (DCs) pode favorecer o estabelecimento da tolerância imunológica. Dessa forma, o direcionamento dos peptídeos tolerogênicos da HSP60, N3 e N7, in vivo, para DCs, com o intuito de essas células apresentarem esses peptídeos em um contexto imunorregulador, pode induzir um estado de tolerância. Assim, nesse trabalho, tivemos como objetivo a produção de anticorpos (Acs) contra o receptor DEC-205 de DCs conjugados com os peptídeos N3 e N7 da HSP60. Esses Acs, ao se ligarem ao DEC-205 nas DCs, podem ser fagocitados, processados e por fim apresentados a células T em um contexto imunorregulador. Para tal, foram realizadas transfecções de células HEK-293T e CHO com plasmídeos codificando as cadeias leve e pesada dos respectivos Acs a fim de se obter essas proteínas recombinantes. Podemos observar que as células HEK apresentaram uma produção mais eficiente dos Acs quando comparadas com as células CHO (120 vs 30 ng/ml, respectivamente), apesar disso a produção dos Acs ficou abaixo do esperado impossibilitando a realização ensaios in vivo. Além disso, realizamos um ensaio de ligação do Ac anti-DEC-N7 a superfície de DCs e observamos que os Acs produzidos apresentam capacidade de se ligarem a superfície dessas células. Concluímos que os anticorpos recombinantes anti-DEC-205 são capazes... (Resumo completo, clicar acesso eletrônico abaixo)
