The aim of this study was to evaluate the quality of weight measurements produced in Primary Health Care Centers in Botucatu and surroundings. 14 Health Care Centers were included, all of them located in four towns in the area of Botucatu (4,555; 5,656; 18,761 and 128,397 inhabitants). General conditions and scale calibration conditions found in those Health Care Centers were evaluated. In order to evaluate the weight accuracy obtained by the local team, 10 adult users of each Center were addressed by the rater during the service routine in order to get a new weight evaluation, immediately after the measurement made by the team. The statistic method applied for checking the weight measurement held in the Heath Care Center and the scales accuracy was the measurement error technique (MET). The results have showed that out of 19 scales, 6 of them overestimated the weight by 50 grams, 1 of them underestimated the weight by 200 grams and the others were accurate. Evaluated as a group, the result of the scale MET was 44.3g. Regarding the conformity of the measures obtained by the MET of the adults weighing in the Health Care Centers compared to the ones obtained by the researcher, the expected result was obtained in only one Center (< 100g). The results have showed data compromise, rather due to lack of health team training than due to the conditions of the equipment used for the measurement.

The great importance of citrus in São Paulo state, particularly in Botucatu city, the and its major expansion in area in recent years and the advancement of techniques for environmental monitoring, such as remote sensing motivated the present research. The aim of this study was the determination the areas and perimeters of citrus in the Botucatu city, São Paulo state, Brazil, obtained through the softwares: Carta Linx, GIS-Idrisi and SPLAN, using aerial colored photographs of 2005, scaled at 1:30000 with longitudinal covering of approximately 60% and 30% laterally. The areas obtained from the aerial photographs and evaluated by Carta Linx presented values closer to the terrestrial reality in determining areas and perimeters, whereas GIS-Idrisi showed discrepancies in the determination of the perimeters, due to working with matrixes. SPLAN and Carta Linx had values for perimeters and areas in close proximity, due to work with vectors.

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses

O núcleo leito da estria terminal (NLET) é uma estrutura límbica localizada no prosencéfalo rostral, no qual constitui uma importante região no circuito neural das respostas comportamentais e fisiológicas a estímulos aversivos. Estudos anteriores demonstraram o envolvimento do NLET nas respostas cardiovasculares desencadeados por estímulos aversivos. No entanto, os mecanismos neuroquímicos locais envolvidos nesse controle pelo NLET ainda são pouco compreendidos. O glutamato é um importante neurotransmissor excitatório no SNC, e evidências têm apontado que a neurotransmissão glutamatérgica é um importante mecanismo neuroquímico envolvido no controle das respostas fisiológicas durante o estresse em várias estruturas límbicas. Entretanto, um possível envolvimento da neurotransmissão glutamatérgica do NLET nas respostas cardiovasculares ao estresse nunca foi investigado. Assim, o objetivo do presente estudo foi estudar o envolvimento da neurotransmissão glutamatérgica no NLET nas respostas autônomas observadas durante o estresse de restrição agudo em ratos. Nós observamos que a microinjeção bilateral no NLET de LY235959 (antagonista seletivo do receptor glutamatérgico NMDA) reduziu a resposta taquicárdica desencadeada pelo estresse de restrição, porém não afetou as respostas pressora e de redução da temperatura cutânea da cauda. O tratamento bilateral do NLET com NBQX (antagonista seletivo de receptores glutamatérgicos não-NMDA) reduziu a resposta taquicárdica e a de redução da temperatura cutânea desencadeadas pelo estresse de restrição, porém sem interferir com a resposta pressora. Dessa forma, nossos dados sugerem que a neurotransmissão glutamatérgica do NLET tem uma influência facilitatória nas respostas taquicárdica e de vasoconstrição cutânea induzidas pelo estresse.
