Analytical prediction of the spin stabilized satellite's attitude using the solar radiation torque

The aim of this paper is to present an analytical solution for the spin motion equations of spin-stabilized satellite considering only the influence of solar radiation torque. The theory uses a cylindrical satellite on a circular orbit and considers that the satellite is always illuminated. The average components of this torque were determined over an orbital period. These components are substituted in the spin motion equations in order to get an analytical solution for the right ascension and declination of the satellite spin axis. The time evolution for the pointing deviation of the spin axis was also analyzed. These solutions were numerically implemented and compared with real data of the Brazilian Satellite of Data Collection - SCD1 an SCD2. The results show that the theory has consistency and can be applied to predict the spin motion of spin-stabilized artificial satellites.

Values of 13,14-Dihydro-15-Keto-PGF(2 alpha), Progesterone and Oestradiol After Injection of Prostaglandin at Different Periods of Buffalo Puerperium

Knowledge of the effectiveness of prostaglandins in uterine involution process led to the development of protocols with its analogues in postpartum period. However, this hormone mechanism of action is not yet fully elucidated. Thus, the objective of this study was to verify if chloprostenol administration, at early or intermediary puerperium, can induce changes on progesterone, PGFM and oestradiol plasma concentrations. 30 Murrah postpartum buffaloes were randomly divided into three groups: CONT (saline, n = 10); CLO2 (chloprostenol at days 2 and 5 postpartum, n = 10) and; CLO15 (chloprostenol at days 15 and 20 postpartum, n = 10). Blood samples were collected from jugular vein to measure progesterone, PGFM and oestradiol plasma concentrations at days 2, 7, 14, 21 and 28 postpartum. CLO2 group presented lower progesterone and PGFM plasma concentrations in relation to CONT and CLO15 groups (0.23 +/- 0.00 and 0.32 +/- 0.11, 0.19 +/- 0.00 and 0.23 +/- 0.11, 0.23 +/- 0.00 and 0.30 +/- 0.19, for groups CONT, CLO2 and CLO15, respectively; P < 0.05). There was no significant difference in oestradiol plasma concentration between experimental groups (P > 0.05). Prostaglandin synthetic analogue administration induced hormonal changes in postpartum buffaloes, which can partially explain its positive effect under reproductive function of this specie.
