Abstract: one of the most severe diseases in common bean (phaseolus vulgaris l.) is golden mosaic caused by bean golden mosaic virus (bgmv, genus begomovirus, family geminiviridae). this study aimed to evaluate the influence of different irrigation systems on the incidence and losses caused by bgmv in common bean. the experiment consisted of the evaluation of three irrigation systems (drip, sprinkler and micro sprinkler), installed as 225m2 strips in the experimental area of the federal university of alagoas, rio largo, al. each strip contained 12 plots of 1m2 each, with 20 plants per plot. the experiment was conducted over two seasons: october 2006 to january 2007 and october 2007 to january 2008. the incidence of golden mosaic was evaluated by visual inspection of symptomatic plants, and the asymptomatic plants were tested for the presence of begomoviruses by pcr. for yield evaluations, the weight of mature grains from all plants was quantified, and the average weight per plant in each plot was calculated. the results indicate that drip and sprinkler irrigation resulted in the highest (62.31%) and lowest (16.74%) incidence, respectively, of golden mosaic. there was no correlation between the incidence of golden mosaic and yield. however, healthy plants yielded three times more grain than diseased plants.

Abstract: this article studies the interaction between telemarketing companies, government bodies concerned with worker health (assisted by university researchers) and a union of telephone operators. it reveals a gap between the measures companies take to face their workers' health problems and the reality of this work. using the statements of these actors in a public prosecution service inquiry on labor, as well as the results of bibliographic research on telemarketing operators falling ill, we studied the position adopted by companies vis-à-vis the risks associated with telemarketing work. we concluded, based on the companies' declarations, that they adopt a position of denial of the risk factors that cause telemarketing operators to fall ill, while confronting the government's labor protection requirements, which evidences the insufficiency of the workers' actions and the limitations of government power in this field.

Abstract: the distinction between convective and stratiform precipitation profiles around various precipitating systems existent in tropical regions is very important to the global atmospheric circulation, which is extremely sensitive to vertical latent heat distribution. in south america, the convective activity responds to the intraseasonal oscillation (ios). this paper analyzes a disdrometer and a radar profiler data, installed in the ji-paraná airport, ro, brazil, for the field experiment wetamc/lba & trmm/lba, during january and february of 1999. the microphysical analysis of wind regimes associated with ios showed a large difference in type, size and microphysical processes of hydrometeor growth in each wind regime: easterly regimes had more turbulence and consequently convective precipitation formation, and westerly regimes had a more stratiform precipitation formation.

Acta Paulista de Enfermagem , 2011, DOI: 10.1590/S0103-21002011000500004
Abstract: objective: to describe the characteristics of the figure-type of a nurse to work in intensive care environments, with reference to the social representations about technology. methods: as a reference, we applied the theory of social representations. a qualitative research approach was used, with interviews with 11 novice and 13 veteran nurses, analyzed using thematic content analysis. results: the meanings attributed to the environment, patients and caring from the social representation of technology, demanded the need for a figure-type of "nurse", characterized by personal qualities such as: proactive, emotional balance, communication/relationship skills; techniques such as observation skills and leadership, speed, dynamism, technical and expressive skills, to work in the scenario of intensive care. conclusions: the clinical competence in these critical units raises the evaluation of cognitive and psychomotor skills of nurses.
