1. USE OF BENCHES WITH REFLECTIVE MATERIAL TO FAVOR PRODUCTION OF RUBBER TREE ROOTSTOCK SEEDLINGS
ABSTRACT Success in production of any perennial tree depends on the use of high-quality seedlings. This study aimed to evaluate cultivation benches with reflective material and protected environments for production of rubber tree rootstock seedlings. The experiments were conducted in two types of protected environments: 35% shading aluminized screen and 30%

3. EFFECTS OF PHOTOSELECTIVE SHADE NETS ON EARLY GROWTH OF SUGARCANE SEEDLINGS
ABSTRACT Sugarcane has a great economic interest in Brazil, so it needs technologies to increase its yield strength, especially for seedling production. This study aimed to ascertain the influence of shading nets on early growth and development of pre-sprouted sugarcane seedlings. An experiment was conducted in a protected environment, in the Rural Federal U

4. Comparação entre variáveis microclimáticas de local aberto e florestal em um bioma da Mata Atlântica, sul do Brasil
Resumo Na região subtropical do Brasil, o ambiente é naturalmente caracterizado pelo clima quente e úmido. Essas condições são fatores preponderantes para a ocorrência da formação florestal na região, o bioma Mata Atlântica. Associa-se que qualquer condição diferente daquela que não seja natural, pode receber de forma diferenciada a condição

5. Determination of Diffused Irradiation from Horizontal Global Irradiation - Study for the City of Curitiba
Abstract Understanding the solar radiation values in the surface is important for the development of solar energy projects, obtaining through radiometers installed in certain places or publications as in solar energy atlases. Typically, solar or weather stations do not have sensors to measure diffuse irradiation due to high investment and the need for const

7. Relação da vegetação natural do Estado do Rio Grande do Sul com as disponibilidades climáticas
Resumo O clima do estado do Rio Grande do Sul (RS) é temperado úmido, condições de vegetação natural do tipo floresta temperada ou decidual, entretanto, em aproximadamente 46,3% de sua área, a vegetação é campestre. Assim, neste estudo, procurou-se colaborar no sentido de melhor entender as relações entre as condições climáticas e a vegetaçã

9. Implementation of a Photovoltaic Panel to Supply Electric Cars Energy Demands
ABSTRACT The gradual shifting of the energy matrix to renewable sources is one of the main global strategies for sustainable development. According to studies, the use of electric energy by automobiles would lead to a reduction in gasoline consumption of 40.7% in 2031, accompanied by an increase in electricity consumption of 42.1% in relation to official pro

10. Conversion Efficiency of Photosynthetically Active Radiation Into Acacia mearnsii Biomass
ABSTRACT The objective of this experiment was to determine the conversion efficiency of intercepted photosynthetically active radiation into biomass of Acacia mearnsii De Wild. seedlings. A forest species, plastic tubes (90 cm3), and 11 evaluation periods (up to 180 days after emergence) were used in this study. The leaf area index (LAI), total dry biomass (
