The object of this work was to verify the utility of a level IV fugacity model to simulate the environmental fate of the insecticide carbofuran when employed in the cultivation of irrigated rice. The model simulated the dynamic distribution of…

The present paper presents EIAR-Uruguay as an environmental management tool for indicating PPR?s participating farmers which practices and technology need improvements, and to facilitating the evaluation of the Project?s accomplishments. This experience has been recently brought to Chile in the…

Socio-environmental impact assessments were carried out on oleaginous crops for biodiesel production under the context of expanding demand in five regions of Brazil. The study brought together representatives of the main interest groups in Delphi-type workshops. Major impacts are related…

Technology impact assessment may be a helpful tool in the decision-making process. The present work suggests a method to evaluate the impact of technological innovation, providing information organized according to criteria and indicators in several areas where the innovation can…

Soy isoflavones are phenolic compounds comprised of aglucones, ß-glucosides and ß-glucosides conjugated with malonyl and acetyl groups. The ß-glucosidases are a heterogeneous group of enzymes which hydrolyse ß-glucosidic links of oligosaccharides and other glucosides conjugates releasing glucose. Thus the objective…

A bactéria Pseudomonas putida tem se mostrado hábil na degradação de vários xenobióticos, porém são poucos os estudos a respeito da segurança de seu uso para a saúde humana. A fim de avaliar os possíveis efeitos toxicopatológicos da bactéria, uma…

Sorption of acetamiprid (E)-N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methylacetamidine), carbendazim (methyl benzimidazol-2-ylcarbamate), diuron (N-(3,4-dichlorophenyl)-N, N-dimethyl urea) and thiamethoxam (3-(2-chloro-thiazol-5-ylmethyl)-5-methyl-[1,3,5]oxadiazinan-4-ylidene-N-nitroamine) was evaluated in two Brazilian tropical soils, Oxisol and Entisol, from Primavera do Leste region, Mato Grosso State, Brazil. To describe the sorption process, batch experiments…

It has been suggested that, in some cases, exposure to environmental contaminants affects children more profoundly than adults. It is important to evaluate adverse health outcomes in children, a population susceptible to toxic chemicals and mixtures. We examined the effects…

La presente investigación se ha centrado en el estudio de la revista de estudios deportivos Citius, Altius, Fortius (1959-1976), una de las de mayor alcance y relevancia de la historia reciente de la cultura física y deportiva. Su importancia se…

Aims: Control of microbial pathogens by using antagonistic microorganisms is a promising
alternative to chemical fungicides. The objective of the present study was to isolate and
characterize soil actinomycetes and to their inhibitory activity against some fungal plant
pathogens.
