Determinação das forças de vínculo em sistemas clássicos holônomos: análise crítica de três métodos

Abstract: Resumo Nesse trabalho, analisamos de maneira critica as peculiaridades e potencialidades de tres abordagens para o calculo das forcas de vinculo em sistemas classicos holonomos, a saber, o formalismo Newtoniano, o formalismo Lagraniano e um terceiro metodo misto desenvolvido pelo fisico brasileiro Nivaldo A Lemos [1] Analisando as solucoes de tres problemas classicos por cada um desses metodos, concluimos que o numero de dimensoes e a quantidade de vinculos do problema influem sobre a eficiencia dos metodos, o que proporcionou o estabelecimento de um criterio para a escolha do formalismo a ser utilizado

Consumption, apparent digestibility and nutrient balance of diets with bovine milk whey for goats.

Abstract: Increasing milk production in countries such as Brazil, India and Pakistan implies the generation of dairy by-products such as nutrient-rich bovine whey which, if used in feeding small ruminants would reduce environmental waste and add value to this by-product. Twenty entire male kids weighing an average 17 kg and 5 months age were used. The diet control was composed by Aruana hay, milled whole maize, pelleted soybean and limestone. Bovine cheese whey at 1.5; 3.0 and 4.5% (DM basis) was added to experimental diets. Variables measured included intake, nutrient apparent digestibility, energy balance, and nitrogen balance. Regression equations and Pearson correlations (P ? 0.05) were determined. The 3% diet resulted in greater ether extract (EE) (g/kg0.75) and digestible EE (P ? 0.05) concentrations compared to 0% whey. The consumption of cellulose (g/kg0.75) was greater (P ? 0.05) for kids on the 3.0% diet compared to 0 or 1.5%. Nutrient apparent digestibility was not affected (P > 0.05) by the inclusion of whey. Kids on the 4.5% diet excreted more (P ? 0.05) fecal N than those fed no whey; these also retained less N (P ? 0.05) compared to animals fed 3.0% or less whey in their diet. All diets resulted in positive energy and nitrogen balances. Bovine whey can be included in male kid diets up to 4.5% of diet without negatively affecting consumption or apparent digestibility of those diets.

Viabilidade econômica da terminação de ovinos em capim-tanzânia com quatro níveis de suplementação concentrada

Abstract: The economic viability of finishing sheep on Tanzania grass under intermittent grazing was evaluated with four concentrate supplementation levels (0; 0.6; 1.2 and 1.8% LW), two herd separation systems (electric and net fence) and three pasture sizes (1.0; 3.0 and 5.0 ha). The analysis was carried out to determine the minimal necessary conditions to have a viable business. Net income, benefitcost ratio, net present value and internal rate of return with an interest of rate of 8.75% per year were verified. The total implantation cost and maintenance to each system was estimated according to Fortaleza/CE market. Sale price between R$ 2.60 to 3.20/kg LW was considered to estimate total budget. The pasture sized 1.0 ha was economically unviable for both kinds of system tested. The system with net fence was more expensive than the one with electric fence. For the systems with supplementation, data showed viability only for a sale price above R$ 3.00/kg LW and, in some cases, in areas above 5.0 ha. KEYWORDS: concentrate supplementation; internal rate of return; Panicum maximum; profitability analysis; production system.

Characterization of undergraduate nursing courses according to the National Student Performance Exam.

Abstract: Objective: to characterize undergraduate nursing courses according to Enade (National Student Performance Exam) in 2010 and 2013. Method: a quantitative documental study was performed and descriptive statistics was used for data organization and analysis. Results: Enade report analysis enabled the identifi cation of a reduction in the total number of institutions providing undergraduate nursing courses that passed the evaluation process. The Southeastern, Northeastern and Southern regions of Brazil included the highest numbers of courses assessed and showed the best results in the two evaluation cycles. Additionally, the courses characterized as “without a ranking” were mainly held at private institutions. Conclusion: the results of these evaluation cycles are important to support investigative and intervention processes about and with undergraduate nursing courses.
