Land-cover classification with remotely sensed data in moist tropical regions in a challenge due to the complex biophysical conditions. This paper explores techniques to improve land-cover classification accuracy through a comparative analysis of different combinations of spectral signatures and textures…

This investigation compares the peritrophic membrane (PM) morphology along the midgut of susceptible (SL) and resistant (RL) Anticarsia gemmatalis larvae to the AgMNPV. The PM increased the thickness from the anterior to the posterior midgut region in both insects strain;…

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…

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…

/Justice Weekly/ was a tabloid newspaper published in Toronto, Canada, from 1946 to 1972. Like other postwar English-language tabloids, it contained police and court news, horse racing information, and an oppositional orientation to the mainstream press. However, under publisher-editor Philip…
