Controle do crescimento e da seleção folicular por fatores locais e sistêmicos na espécie bovina

The regulation of ovarian activity is an integrated process involving extraovarian signals and intrafollicular factors. In such process, gonadotropins have an important role, but not always crucial. The initiation of primordial follicle growth and the early stages of folliculogenesis can occur without gonadotropins, however FSH may affect the rate of preantral follicle growth. On the other hand, the antral follicle development from 1 to 4 mm in diameter is completely gonadotropin-dependent in bovine, and the alternation of dependency from FSH to LH may be part of the mechanism involved in follicular selection. Locally produced growth factors, such as the IGF system, work in association with gonadotropins throughout the follicular growth and can influence follicular selection. Thus, the integration of these extraovarian signals and intrafollicular factors seems to determine whether a follicle will continue to develop or go atretic. This review focuses on the interaction between gonadotropins and intrafollicular factors in follicular development and selection in cattle.

A ludicidade e a criança: (des)arranjos no ensino fundamental de nove anos

The anticipation of the beginning of Elementary School for six-year-old children, recently imposed by the Brazilian federal law, brought controversies and debates about the organization of the curriculum, routines, contents and activities, spaces and objects, conduct of behavior of teachers and parents, as well as about the policies of teachers’ training, amongst other issues. The present article, supported by advances of scientific production on children formal education, considers the changes in the concepts of children education and, consequently, in curricular practices. For this purpose, games and fun are taken as object of analysis and discussion, and the playfulness is proposed as a central curricular axle in the initial years of Elementary Education.

Análise de rentabilidade e risco na produção de cana-de-açúcar na região norte do Estado de São Paulo sob dois tipos de arranjos contratuais

This study was to evaluate the profitability of land use for production of sugar cane in the São Paulo North Region, under risk conditions, from two views: the owner operator and the cash rental operator. The owner operators have higher levels of profitability comparing to cash rental owners, but with higher levels of risk. The land owners aversive to risk fits better to rent system, since the minimum return is greater than the profitability of owners operators. Moreover, if the producer is willing to production risk, the income may reach approximately 3 times that one obtained by the tenants.

Sistema fotovoltaico monocristalino para bombeamento de água

Since ancient times, it has been a huge challenge to all people around the world to manage to get their fresh water, keeping it clean and providing it to every human being, so that it can be used for their daily needs. This is especially true for small properties in the countryside and in isolated areas with low demographic density. Pumping the water in those regions is a solution that rationalizes its use in domestic chores, in animal rearing and in the irrigation systems of cultivated areas. Making feasible local, renewable and non-polluted energetic alternatives is the aim for those areas that are usually far away from the public electric network. Using photovoltaic solar energy is the alternative now proposed. For this objective was built a system with two monocrystalline panels, one pump, two water tanks, two level sensors and a solenoid valve to pump water, using a pump powered an array of monocrystalline solar panels. The main goal was to compare their rate of water flow and their energy consumption. The use of one data acquisition equipment allowed collecting meteorological, electrical and hydraulic values, and also serving for the control and activation of the pumping system. During four months in a row as from April 2009, arrangements with one or two panels were tested. Mathematics correlations and adjustment lines were used to interpret the behavior of obtained dataset. During the analyzed period the system followed the linear equations with great accuracy. The daily average amount of water pumped by the several tested arrays stayed between 1,100 and 2,500 liters, and that is enough to supply a small rural property. The pumping system with two panels effectively showed the major amount of water, but a system with one panel can be an economical solution until 1,500 liters on day. It did not characterize a direct relationship between power or quantity of photovoltaic panels and daily outflow of water pumping.

Novas técnicas de arranjos de semeadura na cultura da soja

Several factors induce soybean growers to seek new alternatives to increase productivity, in order to always surpass the previous harvest. In an attempt to meet this need in order to become more competitive, new technologies emerge. Currently, for example, the plantation system crossover, double row and dense, gaining media coverage and among researchers, aroused interest in research institutions. To date, there are still few studies with a scientific concrete, quantifies the real benefit of these cropping systems. The technique consists of sowing planting crossed the same area twice at right angles, forming checkerboard. In the planting row and the denser planting increases the number of plants per hectare, but the way they are arranged is what differentiates. Apparently these systems imply some issues, such as the use of inputs that the principle would double, as the plant population in the area will be changed, so possibly the incidence of insect pests and pathogens increase in these cropping systems. The purpose of this literature review is to provide updated information on technology, benefit from it, as it is being used and the research being conducted to provide scientific basis for soybean producer.

Saberes locais, mediação e cidadania: o caso dos agentes comunitários de saúde

As discussões sobre o novo significado de cidadania, valorização da diferença e respeito à diversidade de saberes trazem a questão de como as políticas públicas podem ser localmente enraizadas para garantir que essa diversidade seja contemplada em seus processos. Esta incorporação é ainda mais relevante quando tratamos de políticas de saúde, onde a interação entre implementadores e beneficiários é essencial para compreender os resultados da política. O Programa Saúde da Família (PSF) tem tentado mudar as relações entre Estado e beneficiários, aproximando profissionais da saúde dos cotidiano vividos pelos beneficiários onde, muitas vezes, há (re)produção dos componentes que levam às situações de insegurança, insalubridade e doença. No caso desse programa, a análise das políticas públicas deve levar em conta os processos de interação e a ação dos atores envolvidos na implementação do PSF. Este artigo tem como objetivo analisar o papel dos Agentes Comunitários de Saúde enquanto implementadores do PSF. Através de pesquisas etnográficas acompanhando as atividades dos ACS em diferentes municípios, buscamos compreender como eles lidam com seus múltiplos saberes, ativam e desativam referências e adaptam ação para colocar em prática o Programa. A partir de análises de 24 Agentes Comunitários de diferentes municípios, avanlaos na compreensão de como se dão as mediações e as interações em suas práticas e como constroem as políticas públicas enraizando ações a partir dos cotidianos locais, construindo formas alternativas de implementação dessas políticas.
