Um Repositório Chave-Valor com Controle de Localidade

The ever increasing volume of data produced nowadays presents challenges for storing and processing this data. Traditional database solutions are not efficient to face these challenges, especially with respect to scalability. One approach to provide scalability is the adoption of a layered architecture which combines a distributed storage system with a simple access interface. This paper presen...

ALS-INHIBITING HERBICIDES Controle de Gramíneas Anuais com Topramezone em Misturas com Herbicidas Inibidores da ALS

Panicoid grasses are major weeds of maize and sugarcane as well as of several other important grains, including sorghum, pearl millet, and foxtail millet. Pot trials were conducted to study the activity and potential interactions of topramezone in mixture with recommended rates of rimsulfuron or nicosulfuron on three annual panicoid grasses (i.e. Echinochloa oryzoides, E. phyllopogon, and Panic...

Estimador De Velocidad Para Motores De Induccion, Un Metodo Alternativo
