Metodologias de pesquisa para o estudo geográfico da sociabilidade juvenil

This study aims to present the methodologies of research used to carry out the dissertation requirements related to the different times and spaces linked to the youth sociability. The methodologies are about qualitative features not at all unknown to the geography studies despite the little account taken on them. The methodologies are: eyewitness accounts, Oral History, interviews and groups of debate. With this purpose, this work intends to bring some contribution to geographers and beginners that have been looking for methodological references to their researches it also tries to facilitate the discussion on the methodological dimension in the geographical studies.

Falhas reprodutivas associadas com a presença de do vírus da artrite-encefalite caprina, toxoplasma gondii e neospora caninum em caprinos no estado de São Paulo, Brasil

This study aimed at assessing the occurrence of antibodies against the caprine arthritis-encephalitis virus (CAEV), Toxoplasma gondii and Neospora caninum, as well as the associations between the presence of antibodies and the occurrence of reproductive failures in goats. Serum samples were collected from 923 goats of both sexes, over 3 months of age, from 17 dairy farms located in different municipalities of São Paulo State, Brazil. Infections by T. gondii, N. caninum and CAEV were evaluated by indirect methods of diagnosis based on indirect fluorescence antibody test (IFAT), Neospora agglutination test (NAT), and agar gel immunodiffusion (AGID), respectively. A survey was conducted on the farms to obtain information about reproduction dates (abortions, stillbirths and births of weak and premature kids) and zoosanitary management. Antibodies against CAEV, T. gondii and N. caninum was found in 37.81%, 23.62% and 17.23% respectively. There was no significant association between the presence of anti-CAEV antibodies and CAEV/T. gondii or CAEV/N. caninum co-infection, suggesting that CAEV does not predispose goats to infection by these agents. However, when CAEV/T. gondii (p<0.01) or CAEV/N. caninum (p<0.001) co-infection was present, the occurrence of reproductive failures was significantly higher what could indicate that CAEV-induced immunosuppression may predispose goats to develop the clinical symptoms of toxoplasmosis and neosporosis increasing the risks of the reproductive failures.

Delimitação entre os lenhos juvenil e adulto de pinus elliottii engelm

Trees produce different types of woody tissue during growth. The xylem produced in the first years until a certain cambial age is called juvenile wood and has different physical, mechanical, chemical and anatomical characteristics from that produced later, when the cambial cells have matured. Thus, prior knowledge of the quality of the wood is of fundamental importance for choosing the best use of the material. This work aimed at using data from length of the tracheid and wood density to define the age transition from juvenile to mature wood. For this, three Pinus elliottii var. elliottii trees, aged 35 years, were collected at the Itapetininga Experimental Station, located in the state of São Paulo, Brazil. From each tree, disks of about 5 cm thick were obtained 0.05 m above the ground and used to determine the radial density by the gamma ray attenuation method and to measure the length of the tracheids. The results obtained by linear regression analysis showed that juvenile wood is limited to the first seven years of tree growth and the formation of mature wood occurs after twenty years. For the mature wood, there are significant differences among the averages obtained from the tracheid length and wood density.
