This study aims at aprehending how and in what circumstances families formed by couples of different ethnic-racial origins, being one black and one white, prepare and/or assist their children to face the discrimination the might undergo in consequence of racism againt afro-americans. In oerder to achieve the goal, parents and children of two interracial families were interviewed, in a total of seven interviews. We tried to deepen the knowledge on socilization of mixed offsprings within interracial families, from the statements of the parents and the child. The data obtained and analyzed allow us to conclude that the families use up some strategies to assist hteir children in facing the problem of racism and racial discrimination, even though there are difficulties in elaborating them, and they do not constitute, at least apparently, a priority in children education. However, it was possible to observe that there is a construction of racial belonging, and orientation on possible discriminatory acts kids may undergo. Thus, the orientation is associated to discriminatory experiences lived by the children within the expanded family, at school, on the street, in clubs, being attached to strong affective bonds.

The first Law of Fick in one dimension was utilized for the calculation of those fluxes. In this work was calculated the concentrations of the following chemical species: nitrate, nitrite, ammonium, total nitrogen, orthophosphate, total phosphorus, dissolved organic carbon (DOC), cloride, fluoride, sulfate and silica reactive, as well as the biogeochemicals variables in situ: pH, redox potential , electric conductivity, temperature and dissolved oxigen. The Billings reservoir presented the highest fluxes from the sediment to the water column for nitrate, ammonium, chloride and sulfate: 178, 2181, 2945 and 5821 mg cm-2 year-1, respectively, denoting that this environment is suffering great contribution of these nutrients and consequently presents a larger fluxes for the water column. A study of seasonal variation in the water columm of Barra Bonita reservoir was also done for evaluate in the water column in the Barra Bonita reservoir for evaluate the behavior distribution of the chemical species during a complete hidrologic year. The data, for most of the studied variables indicated that during the drought period occurs a decreasing in concentrations, which can infer that those elements should have anthropogenic origin. The nitrate concentration, reaches a pick of 1,9 mg L-1 for the water column in the period of smaller pluviometer index, is one of the indicators of this tendency. Another data group was sampled for the same parameters and refer to the verification of the bedding stratification occurrence in the water column of Barra Bonita reservoir. The result demonstrated that these phenomenon does not happen for this reservoir because the variation in the concentration of the studied variables reflect only the dynamics of the reservoir for your handling, in addiction, there is not separation of masses of water in different horizontal layers caused by differences of temperatures and chemical water composition.
