1. DIRECT CONNECTION PHOTOVOLTAIC SYSTEM IN MULTI-MOTOR APPLICATION FOR THE RURAL SECTOR
ABSTRACT Photovoltaic pumping systems equipped with variable speed drive have been consolidated as an alternative for water supply in rural locations where energy services are unavailable. Such systems are of the direct connection type and, therefore, it is likely that their operation occurs in two situations: when energy is available and when the reservoir

2. 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

5. Y-shaped and fruiting wall peach orchard training system in subtropical Brazil
ASBTRACT Peach as commercial crop in Brazil is usually grown in open vase training system. However, in the 1970s large orchards changed to the Y-shaped system and higher density of plants. This system is the most used in São Paulo state because it allows orchard densification. However, the longevity of the trees is reduced from 15 to 8 years being the exces

10. APROVEITAMENTO DE FONTES ALTERNATIVAS PARA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA E REFLEXOS NOS SEUS CUSTOS / UTILIZATION OF ALTERNATIVE SOURCES FOR REDUCING POWER CONSUMPTION AND ITS CONSEQUENCES IN COSTS
Residential consumption accounts for around one third of total energy consumed in Brazil. The electric shower is the main component of this consumption, along with air conditioning. Hence, much research has been conducted in order to reduce the consumption of this sector and the use of alternative energy sources. Among these include mainly solar and geotherm

12. Usuários de habitação de interesse social e adoção de sistemas de aquecimento solar de água - estudo de caso em Londrina-PR
This research is dedicated to investigate the reasons why the solar water heating systems are not used in large scale on low-income housing in Brazil. There is a global tendency to reduce dependence on fossil energy resources, however, the influence and economic ruling of oligopolies that holds the end-use traditional energy costs demonstrate the vulnerabili
