Conduziu-se este estudo, com o objetivo de avaliar o retorno ao estro pós-parto de ovelhas submetidas a diferentes manejos de mamada. Foram utilizados 56 ovelhas Santa Inês e Bergamácia, 71 cordeiros e 3 rufiões. Os manejos de mamada (MM) foram: 1: contínua; 2: duas mamadas diárias; 3: mamada durante a noite. O período experimental foi dos 15 dias pós-parto até o desmame aos 60 dias. Até os 15, dias de idade os cordeiros permaneceram com suas mães em período integral. No MM 1, as ovelhas permaneceram com seus cordeiros em uma baia, em período integral. No MM 2, as ovelhas passaram a noite em uma baia e o dia em pastagem, momento em que não possuíam contato físico e visual com as crias. Seus cordeiros permaneceram em outra baia em período integral, para onde as ovelhas eram encaminhadas no momento da amamentação. No MM 3, as ovelhas passaram o dia em pastagem e a noite com seus cordeiros em uma baia, na qual os cordeiros permaneceram em período integral. Todas as ovelhas e todos os cordeiros receberam alimentação nas baias. Para identificação das ovelhas em estro foram utilizados rufiões, os quais permaneceram com elas em período integral. Os dados foram submetidos à análise de variância (PROC GLM, Sas®), e as médias comparadas por contrastes. O MM 2 possibilitou retorno ao estro pós-parto precoce quando comparado ao MM 3 e ao MM 1. Houve pouca ou nenhuma influência do anestro lactacional, pois 80% das ovelhas apresentaram estro durante a amamentação.

TEMA: a voz do professor tem sido foco de estudos nas últimas duas décadas devido à alta ocorrência de alterações vocais nesta classe profissional, assim, reforçou-se a necessidade dos professores participarem de ações para garantir saúde vocal. Poucos são os estudos na literatura que descrevem programas e seus resultados. PROCEDIMENTOS: Descrever um Programa de Saúde Vocal desenvolvido no período 2002 a 2005, para educadores de ensino público (infantil e fundamental) do interior do Estado de São Paulo, composto por grupos básicos de voz oferecendo conhecimento teórico prático de cuidados vocais, com triagem da qualidade da voz dos participantes; grupos avançados buscando reorganização dos processos de fonação e do uso vocal em sala de aula. RESULTADOS: em média 56% dos educadores inscritos frequentaram as ações; 62,9% das vozes apresentavam distúrbios na triagem vocal com maioria em grau discreto; no início dos grupos avançados 100% dos educadores participantes referiram mais de 3 sintomas associados ao uso vocal, e após, somente 45% deles ainda de 4 a 13 sintomas; os dados de autopercepção vocal revelaram baixos escores de impacto da voz nas atividades profissionais. CONCLUSÃO: a descrição revelou a necessidade de ajustes constantes do programa para alcançar seus objetivos. A baixa participação às ações pode estar relacionada à presença de impacto discreto da voz nas atividades profissionais, fato a ser mais bem investigado no futuro, e o benefício constatado objetivamente da participação dos educadores nos grupos avançados de voz foi a diminuição na quantidade de sintomas vocais.

The general objective of this work was to develop a monitoring and management model for aquatic plants that could be used in reservoir cascades in Brazil, using the reservoirs of AES-Tiete as a study case. The investigations were carried out at the reservoirs of Barra-Bonita, Bariri, Ibitinga, Promissao, and Nova-Avanhandava, located in the Tiete River Basin; Agua Vermelha, located in the Grande River Basin; Caconde, Limoeiro, and Euclides da Cunha, which are part of the Pardo River Basin; and the Mogi-Guacu reservoir, which belongs to the Mogi-Guacu River basin. The main products of this work were: development of techniques using satellite-generated images for monitoring and planning aquatic plant control; planning and construction of a boat to move floating plant masses and an airboat equipped with a DGPS navigation and application flow control system. Results allowed to conclude that the occurrence of all types of aquatic plants is directly associated with sedimentation process and, consequently, with nutrient and light availability. Reservoirs placed at the beginning of cascades are more subject to sedimentation and occurrence of marginal, floating and emerged plants, and are the priority when it comes to controlling these plants, since they provide a supply of weeds for the other reservoirs. Reservoirs placed downstream show smaller amounts of water-suspended solids, with greater transmission of light and occurrence of submerged plants.

The main variables found on procedure of the dissolution silicate rocks using acid dissolution in teflon open vessel for analysis of micro elements by ICP-AES has been determined. The results obtained for some samples showed strong dependence of the rock mineralogical composition, then it was recommended an alkaline fusion step after acid dissolution. The decomposition procedure use 20 mi of an acid mixture of HF:HNO3 in the proportion 3:1 for a fraction of 250 mg pulverized sample. The recommended temperatures were 60 degrees C for attack and 90 degrees C for acid volatilization. The fusion step with 50 mg LiBO2 at 1000 degrees C may be used if non-attacked residue is observed in the solution. The whole time was 6 h per sample. Nine types os silicate rocks that show mineralogical and chemical different compositions were chosen for obtaining the optimization of the variables. The elements used were Ce, Y, Yb and Zr. In addition, ultrassonic nebulization has been used. The percentual standard deviations obtained for five determinations were 0.7 and 1.4 for triplicate samples. The mineralogical and textural information from the petrographical analysis of the samples indicated the need of increasing the fusion step on the optimized procedure.

The annual litter fall production and the concentrations of macronutrients of four leguminous tree species were evaluated. The experiment was installed in a distrophic red yellow latosol (Oxisol), derivative of the Bauru sandstone group. The studied species were: Leucaena leucocephala. Acacia melanoxylon, L. diversifolia and Mimosa scabrella. The experimental design was randomized blocks, with four treatments (species) and four replications. The litter fall was collected in boxes measuring 50×50×10 cm, two boxes by treatment in each block. The material was collected monthly and dried, weighed and chemically analyzed. The litter fall deposition occurred in the following order: M. scabrella (7,051 kg ha -1 ano -1), A. melanoxylon (2,789 kg ha -1 ano -1), L. diversifolia (1,576 kg ha -1 ano -1) and L. leucocephala (1,389 kg ha -1 ano -1). The content of nutrients obeyed the following order: N>Ca>K>Mg>P>S, with the exception of L. leucocephala that presented a bigger content of S in relation to the P.

The affirmative action issue has split the public opinion and heated up the academic debate. While some experts and black activists see the affirmatives actions as a way to fight racism, since the positive discrimination could help the historically underprivileged to create and empower a positive identity, others see such measures as a dangerous attack against the traditional brazilian way of dealing with human differences. The latter fear that such policies may unleash racial conflicts. Although both sides barely explain what they mean for racism and how they understand that social phenomenon, it is possible to discern in those discourses different lines of argument, which can be related to different theoretical orientations about the analysis of such concepts as race and color.

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii and its definitive host is the domestic and wild felids infecting human beings and other warmblooded animals. Dogs are considered a potential risk on the transmission due they can mechanically transmit oocysts to man. In this study, a retrospective analysis of toxoplasmic infection in dog serum samples sent to Serviço de Diagnóstico de Zoonoses/FMVZ-UNESP/Botucatu, SP, in the period of 1998 to 2007 was performed. During this period 1097 serum samples were analyzed by the indirect fluorescent antibody test (IFAT), with 299 (27.25%) positive. The most frequent titer was 16 (42.80%), followed by 64 (37.79%). The results indicate that T.gondii is distributed in the environment showing the role of the dog as sentinel animal to toxoplasmosis to monitor public health actions to the control of this zoonosis.

The health pact arises in the Brazilian scene after a number of attempts for the improvement of the Unified Health System (SUS), so as to consolidate social equity. In this perspective, this paper discusses the pact using documental analysis, in order to help the public administration process in Brazil. This new policy, still in the initial phase of implementation, is a unique reality and highly feasible for the improvement of national practices in public health. Its performance is intimately related to overcoming the political barriers inherent to each rank of the administration.
