2. Temperature influence on mobility and charge density model of photovoltaic cells
abstract Photovoltaic (PV) devices that capture the energy provided by the sun have great potential as renewable energy sources. However, the input parameters such as the luminous intensity and temperature of the solar cells tend to influence the operating characteristics in the solar panels. The inherent physical processes that cannot be altered limit the e

3. Desempenho lumínico em edificação escolar com estratégias sustentáveis e bioclimáticas : um estudo de caso
New manners on how to inhabit the planet are sought due to the increasing society development, in order to preserve it for the future generation. The seeking for low-energy consumption alternatives is one of the key issues the man can intervene in order to preserve earth´s natural resources. The usage of natural light is extremely valuable in edifications w

4. Photometric procedure for quantitative analysis of Aflatoxin B1 in peanuts by thin-layer chromatography using charge coupled device detector
A photometric procedure was developed for determination of aflatoxin B1 in peanuts by TLC-CCD technique. The quantification and detection limit were 1.2 μg kg-1 and 0.4 ng per spot, respectively, with mean recovery of 98%. The CCD camera is sufficiently sensitive to detect small changes in spots fluorescence intensity and the results for performance confirm

7. Modelling and measurements of illuminance for diverse atmospheric conditions in the northeast of Brazil / Medidas e modelagem da iluminÃncia para diversas condiÃÃes de cÃu no Nordeste do Brasil
In Brazil, and particularly in the Northeast region, illuminance measurements are not a part of the routine measurements in meteorological stations. Therefore, the availability of information on illuminance is rarer than the measurements carried out on solar irradiation. In this context, two stations for measuring illuminance and solar irradiation were insta

11. Uma contribuição a analise de conservação de energia eletrica utilizando a teoria dos conjuntos Fuzzi
A methodology for decision-making in studies involving energy saving by using the Fuzzy Sets Theory is presented. The Fuzzy Sets Theory permits to handle and to operate exact and non-exact propositions, that is, to incorporate both numerical data (exact) and the knowledge of either the expert or the analyst (inexact). The basic conceptsof this theory are pre

12. Marine Transducing Bacteriophage Attacking a Luminous Bacterium
The isolation and partial characterization of a marine bacteriophage attacking a strain of luminous bacteria is described, including some physical, biological, and genetic properties. It is a DNA phage of density of 1.52 with a long flexible tail and an apparently icosohedral head. With respect to stability in suspension, it has a rather specific requirement
