Nation-building e seguran?a internacional: Um debate em constru??o
Gomes, Aureo de Toledo;
Contexto Internacional , 2009, DOI: 10.1590/S0102-85292009000200003
Abstract: this article aims to analyze nation-building operations, which have been considered, since september 11, 2001 terrorist attacks, one of the ways to cope with the new threats to international security, mainly the so-called failed states. therefore, we will review the bibliography published, trying to identity not only the origins of such operations but also the definitions used by the main authors and the problems that they might present.

Abstract: Efficient honey production requires knowledge about the behavior of the workers and the parameters that influence the strength of the colony. In this study, the objective was to analyze the interaction between the foraging behavior of worker honeybees and pollen storage levels in Africanized honeybees colonies. Colonies with low pollen storage increased pollen intake rates, but this value was 15% lower than colonies with high pollen storage, demonstrating a direct relationship between the pollen storage levels and foraging activity. The difference in pollen intake rates varied according to the number of foraging honeybees and pollen load collected by each individual. Under both high and low pollen storage, colonies returned pollen storage to initial level within 16 days, suggesting that honeybees regulate pollen storage levels around a homeostatic set point. Relationship between pollen storage levels and colony brood production was also found, indicating how alterations in the behavior of each individual can affect the strength of the colony.
Air Pollution in the Brazilian Road Transport and Its Environmental and Social Consequences  [PDF]

Abstract: The use of fossil fuels has been greatly increased since the eighteenth century with advent of the industrial revolution. Currently, the use of these fuels is responsible for, on average, 80% of energy generation in human society, producing large emission of pollutant gases and particulate material. Thus the transport sector is a major source of air pollution worldwide. This issue causes serious damages to the environment through phenomena such as acid rain, global warming and photochemical smog. Moreover, the emission of pollutants is also related to damages in human health. Brazil is a country with great territorial dimensions and its transport array is eminently by road, so it is a major consumer of fossil fuels, such as diesel, which has been producing serious environmental and social problems. Thus, this paper presents an analysis of the emission of gaseous pollutants and particulate matter from the transport sector (buses and trucks), gaseous pollutants such as NO2 and SO2 were detected in ppmv concentrations using electrochemical sensors. The composition constituents of the particulate materials emitted in diesel combustion and their respective concentrations were determined by X rays fluorescence spectrometry (XRF). The identified elements were: S, Fe, Si, Ca, Zn, P, Ni, Cr, Ti, Mn and Cu.

Abstract: the neem, azadirachta indica, has been studied in the last years for the use in controlling plant pathogens. the objective of this work was to evaluate the effect of the neem oil, seed kernel extract and leaf extract on the control of the powdery mildew of the bean plant under green house conditions. the emulsified neem oil was tested for concentrations between 0.25 and 2.0% and sprayed before or after the appearance of the symptoms of the disease. the seed kernel extract was produced under laboratory conditions by grinding the kernels in distilled water, which was sprayed 48 hours before or 24 hours after the inoculation of the pathogen. it was also evaluated the efficiency of a commercial leaf extract at the concentrations of 0.25 and 0.5% which was sprayed after the appearance of the symptoms. the results of this work showed that the neem oil was efficient in the control of the disease when applied before or after the appearance of the symptoms. the seed kernel extract controlled the disease at the three tested concentrations. on the other hand, the leaf extract was not efficient in the control of the powdery mildew of bean plant.
Controle de vetores utilizando mosquitos geneticamente modificados

Abstract: the ineffectiveness of current strategies for chemical control of mosquito vectors raises the need for developing novel approaches. thus, we carried out a literature review of strategies for genetic control of mosquito populations based on the sterile insect technique. one of these strategies consists of releasing radiation-sterilized males into the population; another, of integrating a dominant lethal gene under the control of a specific promoter into immature females. advantages of these approaches over other biological and chemical control strategies include: highly species-specific, environmentally safety, low production cost, and high efficacy. the use of this genetic modification technique will constitute an important tool for integrated vector management.
