RESUMO

AIMS: The aims of this study were to quantify donors among the investigated area, quantify arguments and myths about the donation and transplantation process, and fix predetermined donation variables in a logistical model. MATERIALS AND METHODS: We used an analytical, prospective design, using 848 students from 13 high schools in the Velez Sarsfield Hospital area in an open-closed inquiry. RESULTS: Females were 57.74% and average age was 16.64 +/- 0.06 years, including 65.09% Catholics. The 642 potential donors represented 75% of the study population with the fundamental aim being to "give life" (44.85%). The 193 (22.75%) opposed subjects cited as a principal reason fear and distrust (40.41%). There were 40.21% who had discussed the donation subject with their families. In our study 76.41% believed that human organ traffic exists and 36.88% thought that it is due to corruption. Also, 56.01% fear premature extraction of their organs. In addition, 73.23% of teenagers considered that individuals who refused to donate have the right to receive organs (P = not significant between donors and not a donor). The family discussion and the lack of fear about premature extraction were donation signals. About the low level of donation 43.27% blamed the government (lack of campaigns, information, and knowledge) whereas other reasons were fear, lack of clarity and distrust. In our study 49.17% seemed to wish to increase donation if they received more information. CONCLUSIONS: Individuals predispose to donation represented the great majority of the queried teenagers; education and family discussion were remarkable factors favoring the decision.

RESUMO

In this paper a new spectroscopic investigation on the X(1)Sigma(+) electronic ground state of the RbCs molecule is reported. This study is conducted by using laser-induced fluorescence combined with Fourier transform spectroscopy (LIF-FTS). More than 23 000 spectral data are used in a global linear reduction to molecular constants. With these new and improved molecular constants, the potential energy curve has been calculated by the inverted perturbation approach (IPA). Accurate values for the dissociation energy and the long-range parameters have been derived. Copyright 1999 Academic Press.

RESUMO

An experiment was carried out, using 81 castrated male pigs, to estimate the effect of adding butterfat (70% fat, 30% buttermilk), as an energy supplement, to the rations of pigs fed skimmed whey ad libitum. The rations were fed daily in a restricted amount and butterfat added to rations at two levels: T-2 and T-3, 140 and 280 g/day/animal, respectively. In treatment T-1, no butterfat was added. The pigs were weighed every 21 days until they reached average liveweights of 100 (group 1) or 120 kg (group 2), when they were killed for carcass studies. There were significant differences in liveweight gains and feed conversion for the pigs supplemented with butterfat. A negative result, from an economical point of view, was obtained due to the relatively high price of the butterfat. A higher yield of carcass weight on field liveweight was obtained in treatments T-2 and T-3, reflecting the higher degree of fatness. The relative carcass length, muscle depth and percentage of defatted ham were higher in T-1. Conversely, the relative depth of fat was more marked in the groups and treatments that consumed butterfat with their rations. Both groups of T-1 yielded the highest percentage of muscle and the lowest of fat in their carcasses, the differences from T-2 and T-3 being significant. T-2 and T-3 did not differ significantly from one another. There were significant differences in the fatty acid composition due to sampling location. The differences due to treatment were statistically significant in respect of the concentrations of 14:0, 16:1, 17:0, 17:1, 18:0 and 18:1 fatty acids. The unusually low concentration of 18:2 in the dissected fat tissues produces high quality porcine fats, for use in manifactured and prepared foods.
