Redução de desperdícios de corte em empresas Têxtil-Lar

Desnutrição e outras síndromes geriátricas em idosos que beneficiam de apoio ge...

Os problemas nutricionais afectam o estado de saúde, agravando patologias pré-existentes ou levando ao apare- cimento de outras, que por sua vez podem contribuir para a deterioração do estado nutricional,tal como as Síndromes Geriátricas (SG). As SG são condições ou patologias alta- mente prevalentes na população idosa, estando associadas a uma maior mortalidade, incapacidade e necessidade de cuidados, podendo ...

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) t...

Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, Alphitobius diaperinus (Panzer), is an important insect pest in poultry houses in Brazil. Susceptibility of the lesser mealworm collected from eight poultry houses in Paraná state, southern Brazil, was evaluated for cypermethrin, dichlorvos and triflu...

Salt stress induced damages on the photosynthesis of physic nut young plants

Salinity is a major limiting factor to crop productivity in the world especially in semiarid regions. The aim of this study was to evaluate the photosynthetic resistance of Jatropha curcas (L.) young plants subjected to salt stress. The experiment was carried out in a completely randomized design with treatments in a 2 x 3 factorial: two NaCl levels (0 and 100 mmol L-1) and three harvest times: 7 and 14 days of...

Morphostructural characterization of soil conventionally tilled with mechanized...

The structural stability and restructuring ability of a soil are related to the methods of crop management and soil preparation. A recommended strategy to reduce the effects of soil preparation is to use crop rotation and cover crops that help conserve and restore the soil structure. The aim of this study was to evaluate and quantify the homogeneous morphological units in soil under conventional mechanized till...

Seasonality of insects in the semi-arid Caatinga of northeastern Brazil

Insects are essential to tropical ecosystems functioning. In semi-arid regions, the increase in abundance and/or activity (e.g. reproduction and foraging behavior) of insects is usually associated with climatic variables. The present study investigates which climatic variables are best predictors of insect abundance in an area of Caatinga in northeastern Brazil. Individuals were sampled for 24 months using Mala...

Availability of a soluble phosphorus source applied to soil samples with differ...

Considerations on the interactions of P in the soil-plant system have a long history, but are still topical and not yet satisfactorily understood. One concern is the effect of liming before or after application of soluble sources on the crop yield and efficiency of available P under these conditions. The aim of this study was to evaluate the effect of soil acidity on availability of P from a soluble source, bas...
