2. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

3. Integration of Renewable Energy Sources to Operate in Microgrids in Rural Zones in Brazil
Abstract In a world where technology is even more essential, quality and reliability of electrical system are fundamental. In Brazil, country where most of the energy is produced thought power plants, the existing distribution network is overwhelmed and the needs for the consolidation of distributed generation is growing. Wind and Solar power generation fro

6. GEOGRAPHIC MODELLING OF WIND AND SOLAR ENERGY POTENTIAL
Abstract Reducing ‘Greenhouse Gas’ emissions, particularly of CO2, is a global commitment which has gained predominance with the emergence of sources that generate renewable energy as an alternative to traditional energy produced through fossil fuels. Renewable or ‘soft’ forms of energy are all those which use the elements of nature - for example, th

7. Can China's Green Socialism transform global capitalism?
Resumo: Na última década, a China deu um salto espetacular para se tornar o principal usuário e fabricante de energia eólica e solar. Mas seu compromisso com o combustível fóssil ainda supera a energia renovável. O artigo traçará o crescimento da energia limpa e da indústria de carvão e petróleo, no mercado interno da China, bem como em seus inve

8. Multivariate adaptive regression splines (MARS) applied to daily reference evapotranspiration modeling with limited weather data
ABSTRACT. Estimation of reference evapotranspiration (ETo) is very relevant for water resource management. The Penman-Monteith (PM) equation was proposed by the Food and Agriculture Organization (FAO) as the standard method for estimation of ETo. However, this method requires various weather data, such as air temperature, wind speed, solar radiation and rela

9. Penman-Monteith with missing data and Hargreaves-Samani for ETo estimation in Espírito Santo state, Brazil
RESUMO O método de Penman-Monteith (PM-FAO) é recomendado como padrão para cálculo da evapotranspiração de referência (ETo). Contudo, a sua utilização requer uma série de variáveis meteorológicas que normalmente não estão disponíveis, restringindo sua aplicação em muitos locais. Uma solução para o problema de indisponibilidade de dados met

10. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

11. Computational Model for Microgeneration Simulation, From Solar and Wind Renewable Sources, With Optimal Allocation of Loads, Electric Vehicle and Energy Storage, In a Residential Electrical Micro Network
Abstract The electrical sector is under constant evolution. One of the areas refers to the consumers that come to be generators, implementing distributed generation, interconnected to a smart grid. This article discusses the improvement of an algorithm, already presented in the literature, to make the best temporal allocation of loads, electric vehicle, stor

12. Three decades of reference evapotranspiration estimates for a tropical watershed in the eastern Amazon
ABSTRACT This study estimated the reference evapotranspiration rate (ETo) for the Itacaiúnas River Watershed (IRW), Eastern Amazonia, and measured the accuracy of eight empirical equations: Penman-Monteith (PM), Priestley-Taylor (PT), Hargreaves and Samani (HS), Camargo (CAM), Thornthwaite (TH), Hamon (HM), Kharrufa (KF) and Turc (TC) using monthly data fro
