Efeito da tosquia na temperatura corpórea e outros parâmetros clínicos em ovinos

The aim of this study was to determine the variation of the temperature after shearing in sheep under dry and hot environment conditions and to compare the temperature changes with variation in cardiac and respiratory frequencies, ruminal movements and hydration status. Twenty Suffolk unshorn ewes were studied. Physical examination was performed in all animals three times a day at 7:00 AM, 1:00 PM and 7:00 PM, during 42 days (22 days before shearing and 20 days after shearing). The skin temperature was measured by infrared thermometer over several surfaces of the body. Data were submitted to analysis of variance, for comparisons between groups (shorn versus unshorn) at each time, and the significant difference was evaluated at level of P<0.05 by Tukey test. The respiratory frequency was statistically significant at all times. When air humidity was high, the respiratory frequencies were low. The thermal stress was clear in sheep of this study, reflecting marked changes in cardiac and respiratory frequencies and rectal temperature. The respiratory frequency was the parameter more reliable to establish a framework of thermal stress in the unshorn sheep, with values on average three times higher than those reported in the literature. The heart rate monitors the thermal variation of the environment and is also an indicator of heat stress. This variation shows the Suffolk breed is well adapted to hot climates. The correlation between the body surface temperatures with environment temperature and air humidity was negative, as explained by the effect of wool insulation, i.e. even with an increase in environment temperature and humidity, the body temperature tends to maintain a compensating balance. In the shorn animals, the correlation between skin temperature with environment temperature and air humidity showed that the skin temperature increases when the environment temperature increases. The increase in the environment temperature does not affect the body temperature of unshorn animals due the insulating effect of the wool. However, when environment temperature rises, the presence of the wool starts to affect the thermal comfort as the heat absorption is larger than the capacity of heat loss. In this study, the best thermal stress indicators were the respiratory frequency and rectal and skin temperatures. The temperatures of the skin measured at the perineum, axillae and inner thigh were considered the most reliable.

Classificação da cobertura da terra da RPPN Foz do Rio Aguapeí: abordagem booleana para a integração de imagens TM-Landsat e dados multifonte

The Companhia Energetica de Sao Paulo - CESP owns six hydroelectric dams in the state of São Paulo. The dams, both in its construction and in operation, cause some environmental impacts, most of them negatives, for example, the flooding in regions before not flooded, deviation of the river’s course, among others, bringing harm to flora and fauna of these environments. As a way to compensating these damages, the CESP has acquired a region that was influenced by Sérgio Motta Hydroelectric Plant Engineer, or Porto Primavera, and turned it into Reserva Particular do Patrimônio Natural Foz do Rio Aguapeí. By law it fits in a Conservation Unit, and thus should be contemplate for a management plan, ie, a multidisciplinary technical document which allows, simply, the practice of actions within and around in a sustainably way. This work aimed at developing a land cover map of the reserve for this plan can be made and executed more efficiently. Initially, the project included field visits and meetings with members of the CESP to be specified classes contained on the map. Later, we ran different types of classifications of multispectral images (TM / Landsat 5)... (Complete abstract click electronic access below)

Cristo si è fermato a Eboli, de Carlo Levi e Francesco Rosi: memórias da cor de olhos tristes

As a hybrid genre, the narrative of Carlo Levi is an objective account and subjective elaboration that are equalized in a literary form. Written between 1943 and 1944, the book evokes with an atmosphere of memoir the period of 1935 and 1936, the writer’s exile. The film based on the narration fragmentizes the daily life of the problematic region and highlights the truth aimed by the discourses composed in times of crises, reinforced by action and expression without provincialism and also without a compensating aristocratic pose. It is possible to see some incapacity of the film by Rosi, natural to a certain degree, to translate the synthesis of literary treatment and socio-historical reflection. For this reason it is necessary to read the adaptation as an attitude about the literary matter and the result of historical experience. The memoir character relies on the artifice that makes good use of the book’s opening, the author’s short monologue, its narrative frame. The presence of paintings materializes the questions about the absurd contained in them
