1. 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

2. Knoop hardness analisys of a resin composite activated by halogen lamp and LED, varying the luminous density / Avaliação da microdureza de resina composta polimerizada com fontes de luz halógena e LED, em função da densidade de energia luminosa irradiada
No presente estudo, avaliou-se a microdureza da resina composta Z250 (3M ESPE), quando ativada em diferentes tempos (s), diferentes densidades de potência (mW/cm²), em relação à quantidade de energia irradiada (8, 12 e 16 J/cm²), com a finalidade de estabelecer uma densidade de energia luminosa mínima capaz de polimerizar adequadamente os compósitos.

3. As dinâmicas de Schefflera angustissima (March.) Frodin (Araliaceae) e de Andira anthelmia (Vell.) March. (Fabaceae) na reserva de Morro Grande, São Paulo. / The dynamics of Schefflera angustissima (March.) Frodin (Araliaceae) and Andira anthelmia (Vell.) March. (Fabaceae) in the Morro Grande reserve, São Paulo.
Population dynamics deals with variation in time and space in the density and abundance of populations. The studies about the dynamics of tropical rain forest tree species, in particular, have become popular only about 1970, when the extinction risks for species of economic interest became pressing. Because the Brazilian biomes are being destroyed progressiv

4. The associated Planting among banana (Musa acuminata cv. Big it Sleeps) and "feijão-de-porco" (Canavalia ensiformis (L.) D. C.): an agronomic evaluation of the effects of the competition for water, nitrogen and luminous energy / O plantio associado entre banana (Musa acuminata cv. Grande Nane) e feijão-de-porco (Canavalia ensiformis (L.) D. C.): uma avaliação agronômica dos efeitos da competição por água, nitrogênio e energia luminosa
In tropical regions, intensive banana (Musa accuminata) monocropping has severe agronomic and environmental impacts, and the sustainability of this production is actually highly compromised. Yield reductions are principally due to the decrease of soil fertility and root systems damages by sod fungus and nematodes. Several alternatives actually aim to improve

5. Growth, luminescence, respiration, and the ATP pool during autoinduction in Beneckea harveyi.
The bacterial bioluminescence system is unusual because it is self-induced. In the late logarithmic phase of growth, upon the accumulation of an autoinducer, the synthesis of the components of the system is initiated. We were interested in determining what effect this burst of synthesis and activity has on cellular energy metabolism. The ATP pool of the lumi
