The role of proestrus on fertility and postovulatory uterine function in the cow

Modern protocols to synchronize ovulations for timed artificial insemination and timed embryo transfer that include manipulations in the proestrus period (i.e., between luteolysis and estrus) affect fertility in cattle. Specifically, stimulating pre-ovulatory follicle growth and exposure to estrogens after CL regression increase the proportion of cows pregnant and decrease late embryo mortality. Such effects may be due to both preovulatory actions of estrogens and post-ovulatory actions of progesterone, as concentrations of the later hormone may be changed in response to manipulations conducted during proestrus. In the first portion of this paper we describe strategies used recently to manipulate the proestrus period in protocols for synchronization of ovulation, and to present evidence of their effects on fertility. Manipulations of timing and prominence of sex steroids during the proestrus and early diestrus that affect fertility may act on targets such as the endometrium. This tissue expresses receptors for both estrogens and progesterone and these hormones change endometrial function to support conceptus growth and pregnancy maintenance. However, specific cellular and molecular mechanisms through which fertility is affected via manipulations of the proestrus are poorly understood. In the second portion of this paper we describe a well-defined animal model to study changes in endometrial function induced by manipulations conducted during the proestrus. Such manipulations induced endometrial changes on sex steroid receptors expression, cell proliferation, oxidative metabolism and eicosanoid synthesis in the uterus, but not on glucose transport to uterine lumen. In summary, evidence is accumulating to support a positive role of increasing duration and estrogen availability during the proestrus on fertility to synchronization protocols. Such positive effects may be through changes in endometrial function to stimulate conceptus growth and survival.

Planejamento ambiental do distrito de Ameliópolis – Presidente Prudente - SP

The concern with the environmental planning has become important in Brazil recently. Until then, nature was conceived as a resource, because of the implementation of developmental policies that perdured to the 1970s, based on the expansion of the industrial complex, altogether hadn´t preoccupation by the federal government with the relationship between society and nature. During this period, after the threat of not receiving more international investment to finance large projects in the country, accompanied by pressure from civil society organizations, the federal government began to take some action related to the environment, such as the creation of federal agencies (IBAMA), application of environmental laws and decrees in order to create rules for the proper use of natural resources such as water, soil and air. From the decade of 1990 onwards the master plans have become a mandatory document for all municipalities in the country with a population over 20,000 inhabitants, ranging from health issues to the development of urban, rural and environmental planning. Thus, the environmental planning gained prominence in the political scene. Therefore, to achieve environmental planning is necessary to follow some social and environmental parameters, which for this survey, conducted in the District of Ameliópolis – Presidente Prudente...

Produção de polpa solúvel a partir de Eucalyptus urograndis

The wood of the gender Eucalyptus occupies a prominence place in relation to other cellulose sources, due to its chemical composition, its low cost, abundance and availability. The dissolving pulp obtaining occurs basically starting from three stages: prehydrolysis of the wood following by cooking and finally by the bleaching process. In the dissolving pulp production is necessary a pretreatment stage for the hemicelluloses removal. Among the chemical cooking processes, the Kraft process is the most used for cellulosic pulps production starting from eucalyptus, in the additive presence or not. The anthraquinone uses in the pulping process has as main purposes increasing the delignification rate as well as protecting the pulp regarding the degradation of the polysaccharide chains. The ECF bleaching process consists of the purification of the pulp through bleaching agents, being excepted the elementary chlorine. The dissolving pulp is a pulp of high a-cellulose content and purity destined to the cellulose derivatives production as carboxymethyl cellulose, nitrocellulose and microcrystalline cellulose. The production of a certain product, as well as its final application, is determined by the chemical properties of the pulp. The present work had as purpose producing cellulosic pulp with kappa number around 9 destined to the production of dissolving pulp in way to evaluate the use of the anthraquinone (AQ) in the Kraft process according to the chemical properties of the obtained pulps. It has been still intended developing an effective technology of bleaching for the high purity and quality dissolving pulp production. The prehydrolysis was accomplished in laboratory rotational autoclave for 30 minutes at 170ºC in the water:wood rate 3,5:1 (L:kg). The Kraft/AQ pulping were accomplished in laboratory rotational autoclave being initially modified the active alkali load (10, 13, 16 and 19%) at sulfidity of 25% ...

Introdução de Lentinulaedodes (Shiitake) e Pleurotusostreatus (Shimeji) em bagaço de cana termo explodido para diminuição da toxicidade

Ethanol production has gained great prominence in the investment new renewable energy sources and Brazil is among the leaders of production. However, this activity generates large amounts of waste being the largest volume of the sugar cane bagasse. For this reason looking up ways to use this material as burning for energy production and composition of forage in the diet of ruminants, however there are difficulties to use this production for this last one. This paper proposes a microbiological treatment with Lentinula edodes and Pleurotus ostreatus in order to enable the bagasse in ruminant feed composition in order to be used more noble than their burning. After treatment with the fungus, tests were performed for quantifying crude protein by the method of Kjeldhal. It was verified that the protein content in the pure bagasse was 1.0% after fermentation the protein content was 4.2% with L.edodes and 4.9% with P. ostreatus. To evaluate the protein quality of the product fermented by L. edodes and P. ostreatus was applied microbiological method for growth of Enterococcus zimogenes verifying that after fermentation the protein quality was 76 and 27.4% with L. edodes and P.ostreatus, respectively, compared with casein. The quantification of amino acids showed significant improvement of protein with altered amino acid profile with treatments of fungos. About of DQO and BOD were also found considerable improvement besides considerable drop in toxicity as measured by acute toxicity test with Daphinia similis

Discurso e motivação: um estudo semiótico sobre livros de autoajuda de desenvolvimento profissional

The success and recognition for their dedication put into the work are the need of every worker, and for that there is a constant quest for success in organizations. In this scenario, the Brazilian publishing market offers self-help literature as a practical method of acquiring the fundamental knowledge for professional development. The self-help literature for professional development addresses motivation as an essential characteristic for success, as a motivated worker earns more visibility and prominence to motivate other team members, thus arousing a spirit of leadership among the players. The motivation of workers also meets the expectations of organizations, because they improve productivity without requiring new investments. Thus, the literature on professional development is positioned as one of the best selling literary styles sold in Brazil over the years. To have an understanding of the discourse of literary style and persuasive methods known in them, we present a semiotic analysis of the five introductory chapters of selected works. Greimassian Semiotics offers great tools for understanding the introductory speeches of professional development books, which are intended to present the synthesis of the work, or demonstrate the values and knowledge of the authors, coaxing the reader to read on and be receptive to the idea of motivation presented in the books

Os ídolos nas revistas teen: uma análise de Atrevida, Capricho e Todateen

This study aims to conduct a comparative analysis of the cover stories of magazines Atrevida, published by Escala, Capricho, published by Abril, and Todateen, published by AltoAstral, published between 2008 and 2012, which give prominence to the phenomena with more recurring presence on the covers. The objective of the research is to analyze the criteria for newsworthiness adopted by publications targeting a teenage audience, relating them to cover highlights involving idols of that audience. As object, we study the press coverage given to four magazines phenomena of cultural industry: the actors in the Twilight saga, the actors of the Disney Channel series, singer Justin Bieber and actors of Brazilian soap opera Rebelde. The work begins with a history of magazine journalism, from its origin to the journalism geared toward teenage readers, through the history of women's magazines and variety. Then, we present the theoretical concepts from the Theory News (Traquina) in confrontation with the notions of consumption (Canclini) and behavior (Featherstone). Finally, analysis of the corpus, which was defined by a cutout thematic within this period, divided into two major groups of news reports: those in which the idol is the news, and those in which he serves as a guide for the reader

Gestão do ouro azul no contexto globalizado Neoliberal: bem econômico ou bem social?

The neoliberalism based on the Washington Consensus advised privatization as the most effective alternative for the management of natural resources. The question is what is prioritizing efficiency, market or welfare? The growing concern about the water issue has been highlighted in discussions in international policy debates, and what it turns out is the prominence of corporate and economic interests over social and environmental. The water is in crisis, there are several sources of popular conflicts around the world contrary to how this resource is being offered, as the Water War occurred in 2000 in the city of Cochabamba. It is necessary to respect its limitations to ensure their future availability and choose the best development model that favors the effectiveness of their control. The international proliferation of commercial vision concerning water stipulated privatization of their management as ideal rule, which increased rates, concentrated income, has not improved the quality nor promoted the conquest of equal access to water for most systems that provides these services, this is, privatization has not brought positive results that outweigh the harm of its implementation. Water is an essential commodity for life of living beings, in all its stages, basic reason to develop plans, rules and commitments that ensure its conservation and provide, as soon as possible, a valid alternative for the sustainable management in long term

The article seeks to show what is necessary to the game industry be able to establish and remain on the market, and what is the obstacles that this industry will face in Brazil, a potential creative economy country

Espanha e Brasil na construção da participação democrática: clivagens e consensos

The article searches to launch some analyses and investigations on the historical reach of produced participative processes in Spain and Brazil. Evidently, both the processes if had uncurled in historical, social, economic contexts and distinct politicians, but, exactly thus, keep some approaches that we intend to give prominence in the present article. For example, the popular mobilization in the two presented cases after occurred a long period of not attendance of social demands socials. In the same way, the processes of democratic renewal of both are related with historical landmarks “end of the Cold War” and the dismantlement of the Walfare State that introduced new rationalists in the relation between governing and governed dynamic, over all in the coinage and offer of public politics. How much to the dismantlement of the Welfare State, we present, still, that in the case of Spain it provoked consequences in the modus operandi of the formularization process and implementation of public politics. It occurred, in other words, a decentralization of its formulator power to decide arrangement of public politics that started to count on the participation of social actors in the called relational city (BECERRA, 2011). In the case of Brazil, the dictatorial period (1964-1985), the fast urban growth and the generation of precarious peripheries in the main cities, the distension and the Constituent (1986-1988) had generated the enough forces of pressure so that, gradually, if it incorporated the participative arrangement in the power to decide process. We identify that in both the cases, kept the had ratios, the instauration of a critical scene of suppression/absence of formulated public politics from an interface with the social movements were the propeller spring of the transformations in the power to decide mechanisms of formularization and implementation of public politics.
