1. Conforto térmico em espaços abertos no clima quente e úmido: estudo de caso em um parque urbano no Bioma Mata Atlântica
Resumo Estudos de conforto térmico em espaços climatizados apresentam limitações ao desconsiderar a adaptação do indivíduo às condições ambientais. Com objetivo de superar as limitações dos modelos atuais de conforto térmico, pesquisas têm sido realizadas para identificar os limites de conforto em ambientes sem climatização e em condições n

2. Modeling the reflection of Photosynthetically active radiation in a monodominant floodable forest in the Pantanal of Mato Grosso State using multivariate statistics and neural networks
ABSTRACT The study of radiation entrance and exit dynamics and energy consumption in a system is important for understanding the environmental processes that rule the biosphere-atmosphere interactions of all ecosystems. This study provides an analysis of the interaction of energy in the form of photosynthetically active radiation (PAR) in the Pantanal, a Bra

3. Balanco de radiacao e energia da cultura de alface em estufa de polietileno.
Objetivou-se, neste trabalho, determinar os balancos de radiacao e energia da cultura de alface (Lactuca sativa, L. cv. Veronica) em estufa de polietileno. O experimento foi realizado em uma estufa tipo tunel alto com cobertura de polietileno (100 um de espessura) e em uma area externa, ambas com 35 m2. Durante o ciclo da cultura, foram monitoradas as radiac

4. Action of ultraviolet radiation on the reduction of microbiota from cachaça-producing sugarcane / Ação da radiação ultravioleta na redução da microbiota do caldo de cana para produção de cachaça
The fermentation process for the production of cachaça (the most popular alcoholic distilled beverage) in Brazil is influenced by the quality of the raw material. Thus any raw material containing a high microbial load results in an ineffective fermentation, which is reflected on the final quality of the cachaça. This study evaluated the action of ultraviol

5. Disponibilidade da radiação fotossinteticamente ativa ao longo de colunas de cultivo vertical de morangueiros em função do espaçamento e superficie refletora / Availability of Photosynthetically active radiation alone the columns of vertical strawberry growth in function of spacing and reflective surface
The objective of this research was to increase the offer of Photosyntetically Active Radiation(PAR) trough vertical bags for strawberry production. To aim this objective two strategies were adopted the increase of distance among columns of the vertical bags and the use of reflective surfaces over the floor of the greenhouses under the bags. The distances use

6. Construção e análise de desempenho de um forno/fogão solar tipo caixa construído a partir de uma sucata de pneu
An alternative box-type solar cooker built starting from the scrap of a tire and a scrap of old office chair is presented, which principles functions are the effect greenhouse and the concentration. The tire served as structure for making of is the baking enclosure where the absorber (roasting pan 20x30cm) of the solar is located, being re-covered for a glas

7. Albedo of an Amazon tropical rainforest: field measurements, remote sensing, modeling, and its influence on the regional climate / Albedo de uma floresta tropical Amazônica: medições de campo, sensoriamento remoto, modelagem, e sua influência no clima regional
Albedo is defined as a ratio between reflected solar radiation and incoming solar radiation over a surface. It is a main factor that affects the terrestrial radiation balance and has been frequently considered in the global and regional climate studies. Amazon is one of planets regions where the response of regional atmospheric circulation is more intense. S

8. Estudo das radiações solar e terrestre acima e dentro de uma floresta tropical úmida / Solar and terrestrial radiation above and inside a tropical rain forest
In a micrometeorological experiment accomplished during the campaign WETAMC/LBA (from 26/01 to 10/03/1999) measurements of solar and terrestrial radiation were made on a tropical forest environment, at Biological Reservation of Jaru- RO (10° 05 S; 61° 56 W). Data of incident and reflected solar global radiation flux were collected using pyranometers, incid

10. Estudos dos efeitos atmosfericos sobre as radiacoes percebidas pelos sensores a bordo de plataformas orbitais (ERTS/LANDSAT) / Studies of atmospheric effects over radiations perceived by the radar on board an orbital platforms (ERTS/LANDSAT)
The solar radiation reflected by targets on the earth s surface interacts with the atmosphere before being detected by the satellite sensors. In the visible wavelenght region, scattering by molecules and aerosols predominates on the interaction of the radiation with the atmosphere. In addition to attenuation, this interaction also contributes with diffuse ra

11. Effects of Ionizing Radiation on Synchronous Cultures of Escherichia coli B/r
The sensitivity of Escherichia coli B/r to X-irradiation is correlated with the replication cycle of deoxyribonucleic acid (DNA). The sensitivity to X-irradiation in the wild type can be attributed to the presence of nuclear targets plus DNA repair mechanisms. The effects of nuclear targets are observed in the recombination-deficient (rec−) mutant B/r, but

12. In vivo31P NMR study of the metabolism of murine mammary 16/C adenocarcinoma and its response to chemotherapy, x-radiation, and hyperthermia
31P NMR spectroscopy with surface coils has been used to monitor, in vivo, the phosphate metabolism of subcutaneously implanted mammary 16/C adenocarcinoma in C3H/He mice. This model tumor was studied during untreated tumor growth and after treatment with adriamycin, hyperthermia, and x-radiation. The mammary 16/C tumor exhibited a Gompertzian growth pattern
