This study, clinical, prospective, randomized study was conducted from August 2004 to February 2008 in a convenience sample of 60 women who underwent breast surgery with axillary dissection, divided into two groups (n = 30). The GI (Guidance Kit with different textures, to perform at home) and GII (control). The objective was to analyze the effect of home orientation in patients after surgery for breast cancer complaining of numbness, evaluation, and the conventional esthesiometer. The surface sensitivity was assessed by monofilament Semmes-Weinstein and evaluation using conventional two test tubes with hot water (38 to 43o C) and cold (16 to 27o C), paintbrush, needle. The GI was subjected to 10 sessions and assessments in both 3 times. The M1 (pre intervention), the M2 (post-intervention) after 10 sessions of physical therapy intervention and M3 (washout) after 3 months the second time for assessment. The region targeted for evaluation and intervention was the sensory nerve dermatome intercostobrachial. In the test of Goodman (conventional assessment) there was improvement in both groups, the P1, during the thermal evaluation. The t-test of student (esthesiometer) there was improvement in P2 only in GI (p = 0.003) between points 1 and 2 while the time 3 (p = 0.121 and p = 0.733 respectively). It was concluded that there were divergent and opposite results after examining the effect of home orientation in the nerve dermatome intercostobrachial, evaluation, and the conventional esthesiometer.

The aim of this study was to evaluate the effect of glutamine supplementation of the diet on intestinal mucosa morphology, performance, and egg quality of commercial laying hens, submitted to heat stress and thermoneutral conditions. In this study, 96 (Isa Babcock) laying hens at 35 weeks of age were used and distributed in a completely randomized design according to a 2x2 factorial arrangement, with two levels of ambient temperature (thermoneutral and hot) and two levels of glutamine in the diet (0.0 and 1.0% of inclusion), in 6 replicates of 4 hens per box. Feed intake, daily egg production, feed conversion per kilogram of eggs, and egg quality were obtained in two periods of 28 days each. Heat stress decreased egg production and quality, and glutamine supplementation improved egg quality and feed conversion. The heat and glutamine supplementation provided an increase in calliciform cells quantity in duodenum and ileum, respectively. Significant morphological modifications in the intestinal mucosa of laying hens were not found.

Usage of pesticies in excessive doses or in an inadequate way to control diseases, pests and weeds, has promoted significant environmental damage, contamination of animals, intoxication of farmers, among others. These factors lead to occur the resistance of weeds, pests and pathogens, the appearance of iatrogenic diseases, biological imbalance and reduction in biodiversity. Seeking less aggressive alternatives, plant extracts have been used successfully. Compared to synthetic products, they offer great advantages as generating new compounds, which pathogens are unable to inactivate, and are less toxic, of rapid degradation in the environment, they have broad modes of action, and are derived from renewable resources. It should be emphasized that there are some limitations on its use. The extracts have potencial as insecticide, fungicide, herbicide and nematicide and are considered of good efficiency. The methodologies for obtaining can be achieved through cold extraction, open and closed hot system. The use of plant extracts reappears as a promising and unique option for integrated management in plant protection, being considered as an alternative to control plant pathogens, demonstrating excellent results without causing harm to the environment and living beings.

Cerca de 90% das plantas com flores e 35% das culturas agrícolas são dependentes de animais para polinização, e as abelhas são os principais agentes polinizadores de uma ampla variedade de espécies de plantas de ambientes naturais e agrícolas. Assim, as abelhas não só são imprescindíveis para a manutenção e conservação de comunidades de plantas em sistemas naturais, como também na atuação direta e significativa na produtividade agrícola. Atualmente, as populações de abelhas estão em declínio no mundo todo, em decorrência, principalmente, do crescente desmatamento e consequente perda de habitas adequados, além de outras ações antrópicas que modificam os seus nichos. Tendo em vista que muitos estudos, realizados principalmente em regiões temperadas, têm demonstrado que a paisagem do entorno dos cultivos agrícolas influencia a diversidade e abundância de polinizadores, avaliações sobre o efeito do contexto da paisagem na fauna de abelhas se tornam fundamentais. Este estudo teve como objetivo geral identificar os fatores que influenciam a riqueza e a abundância/diversidade de abelhas nativas em áreas agrícolas inseridas em um gradiente de quantidade de habitat e níveis de heterogeneidade da paisagem. O estudo foi conduzido no município de Guapiara, SP, região predominantemente agrícola, com fragmentos florestais de Mata Atlântica no entorno das propriedades rurais. Para amostrar a distribuição e a diversidade das abelhas foram usadas armadilhas do tipo pan trap (nas cores amarelo, azul e branco). Em cada ponto amostral foram instaladas cinco estações (cada estação composta por um pan traps de cada cor) de 1,5m de altura, cuja distribuição espacial dentro das propriedades de estudo tem formato de X e distantes uma das outras 5m. As amostragens foram de 30h/coleta em cada ponto amostral (n=17, cada um com raio de 1000m), realizadas em uma única época do ano (primavera/verão, quente e chuvoso)...

This study aims to analyze the capacity of a helical coil heat exchanger to reach the requested heat transfer rates by a sodium hypochlorite production process. This heat exchanger was installed in an experimental way in order to reuse a source of low-temperatures water in such a way to become a more economical alternative than the existing cooling tower. Firstly, the concepts related to the theory of heat transfer applicable to the case were introduced. Then, the mapping of the main information about the production process and the technical specification of the current cooling system equipment's was realized. Using the dimensions of the heat exchanger installed today as reference, the calculations for determining the ideal length of the coil to different flows of hot fluid were performed. Finally, it was concluded that the heat exchanger currently employed does not provide heat transfer rates required for the maximum flow rate value supported by the cooling tower
