A água subterrânea é um importante recurso ao abastecimento público, principalmente para comunidades periféricas em grandes cidades ou pequenos municípios, onde a instalação ou prolongamento de sistemas de distribuição são economicamente inviáveis. Estudos voltados à análise da vulnerabilidade de aquíferos são relevantes para subsídio a políticas públicas em saneamento básico e preservação ambiental. Este estudo contou com o cadastro de 23 poços rasos localizados no município de Caçapava do Sul (RS), onde foram realizadas medidas de resistividade elétrica e cargabilidade por meio de geofísica, e medidas diretas de condutividade hidráulica e sólidos totais dissolvidos. A análise estatística dos dados demonstrou diversos graus de correlação entre parâmetros, basicamente condicionados a fatores geológicos como porosidade, permeabilidade e sólidos totais dissolvidos.

This work aimed to study evaporation distribution in a protected environment. The experiment was set up in polyethylene greenhouse at the Lageado Experimental Farm in the School of Agronomic Sciences (FCA, UNESP-Botucatu) in the winter of 2005. 132 500-ml plastic micro evaporimeters (13.7 diameter) were used used to obtain evaporation values and analyze spatial energy distribution. These micro evaporimeters were distributed in 44 equidistant points, at three different heights from the soil surface: 0.40, 0.80 and 1.20cm The tunnel-type greenhouse was 7.5 m wide, 27.5 m long and 3.20 m high at the center, and was covered with black shadow screen (sombrite) on the sides. Southeast/northwest orientation, based on true north, was used foro othe greenhouse longitudinal axis. For variable comparison, a geostatistics was used through the □GS+ program. From obtained data, it was concluded that: there was spatial variability at different points and heights of the microevaporation values obtained from micro evaporimeters were not greenhouse; the Class A Pan installed outside the greenhouse can be used to evaluate the internal evaporation.

This work aimed to study the energy distribution in protected environment during the winter of 2005. A plastic tunnel (27.5 m long, 7.5 m wide, 3.2 m high in the center and 2.00 m high in both lateral sides) was covered with polyethylene 100 micra and black shadow screen (sombrite) in lateral sides at the FCA/UNESP, Botucatu - SP. 142 minievaporimeters (500 ml volume and 147 cm2 area) were evenly distributed and set up at three heights: 0.40 m; 0.80 m and 1.20 m from soil surface in order to analyze energy distribution along the studied area. The greenhouse longitudinal axis was northwest/southeast, based on true north. Geosatistics principles and the GS+ Program were adopted to compare variables. From obtained results, it was concluded that there were significant evaporation variations at different points anf heights; the highest values were the ones closest to the soil surface (0.40m) in July and at highest heights (0.80 and 1.20m). Highest evaporations occurred in the southeastern side of the greenhouse.

Female athletes are more susceptible to injury when compared with males. This increased risk of injury, may be caused by fertile-menstrual cycle. The aims of this study were to investigate the prevalence in the occurrence of muscle-tendon and ligament injuries in different phases of the menstrual cycle over a period of high performance sports training and identify possible differences of occurrences between the phases. Fifteen female athletes, members of a women's basketball team, with ages between 15 and 22 years (average 17.5 ± 2.6 years), with regular menstrual cycles and daily practitioners of training, received follow-up during the menstrual cycle for 5 months. During the period were noted occurrences of injury in relation to the menstrual period of each athlete. The results showed 13 injuries, all of anterior cruciate ligament. The distribution of percentage values indicated a significantly higher risk of athletes suffer injuries in the follicular phase. The result makes us believe that significant elevations in the concentrations of estrogen in this fertile menstrual cycle phase, more open women to a higher risk of performing different injuries.
