As condições e o sentido do trabalho doméstico realizado por adolescentes que residem no local de emprego

The house work is a reality for girls of humble class and one of the most found forms of work among adolescent workers. Moreover, it is a mean of work which reproduces poverty and gender relations within the society. The purpose of this essay in to understand the house work in the life of adolescent workers, emphasizing the meaning produced by these teenagers concerning the job they perform. In order to achieve such goal, questionnaires were applied to 332 adolescents, under 18 years old from public schools (from EJA-supletivo) in Natal, with the purpose of mapping the registration of this activity among young students. Next, 14 adolescents were interviewed in order to recognize the meaning of this work and its repercussions over the teenagery, such as school education, socialization, relations with employers and adolescent s self-image. Later we have noticed most workers among the students from public schools are housemaids. Furthermore, this work is used as a form of social ascension and it contributes for the search for better opportunities in the state capital for adolescents who leave the countryside trying to agree to education and remuneration. This work plays an important role, which is to reproduce gender relations, as a woman works to maintain the private space as a female space and maintains the man out of this relation. Besides it reproduces class relations, ethny and generation conflicts, in which the employer replaces the control the parents have in the adolescent s life. Summing up, this study about house work have negative aspects, related to exploitation, humiliation and mistreat, as well as positive ones, for it permits the adolescent to improve his life conditions. The most important thing is to look for a mean of work in which human and workers rights are respected

Methane and carbon dioxide seasonal cycles at urban Brazilian inland sites

Methane and carbon dioxide seasonal cycles during years 1998 and 1999 at two Brazilian urban and inland sites are presented. The mixing ratio averages over the studied period of time were 1.80 ppm CH4 and 384.7 ppm CO2. A comparison is made between continental averages and the averages of the three nearest global network background sites of NOAA-CMDL comprising Ascension Island, Namibia and Easter Island. Inland sites had 0.08 ppm or 4.9% more CH4 and 19.0 ppm or 4.9% more CO2 than background over the same time span. The CH4 summer minimum observed in remote sites was also detected inland. During the month of October 98 and 99 inland mixing ratios were frequently similar to background.

Spin stabilized satellite's attitude analytical prediction

An analytical approach for spin stabilized attitude propagation is presented, considering the coupled effect of the aerodynamic torque and the gravity gradient torque. A spherical coordination system fixed in the satellite is used to locate the satellite spin axis in relation to the terrestrial equatorial system. The spin axis direction is specified by its right ascension and the declination angles and the equation of motion are described by these two angles and the magnitude of the spin velocity. An analytical averaging method is applied to obtain the mean torques over an orbital period. To compute the average components of both aerodynamic torque and the gravity gradient torque in the satellite body frame reference system, an average time in the fast varying orbit element, the mean anomaly, is utilized. Afterwards, the inclusion of such torques on the rotational motion differential equations of spin stabilized satellites yields conditions to derive an analytical solution. The pointing deviation evolution, that is, the deviation between the actual spin axis and the computed spin axis, is also availed. In order to validate the analytical approach, the theory developed has been applied for spin stabilized Brazilian satellite SCD1, which are quite appropriated for verification and comparison of the data generated and processed by the Satellite Control Center of the Brazil National Research Institute (INPE). Numerical simulations performed with data of Brazilian Satellite SCD1 show the period that the analytical solution can be used to the attitude propagation, within the dispersion range of the attitude determination system performance of Satellite Control Center of the Brazilian Research Institute.
