Revisão sobre fármacos quirais e a sua importância na medicina atual

Aspects are discussed on the chirality of drugs and their action in the human body, the benefits of using a drug in enantiomerically pure form and why, even today, despite the risks, many drugs are marketed as racemic mixture. Among the methods of separation there is the High Performance Liquid Chromatography (HPLC) which can be given in different ways using chiral additives in the mobile phase as in the system of ligand exchange in the ion pair system and the system of cavity or inclusion. Note also the wide variety of chiral stationary phases available in the market that allow high specificity using them according to the need and purpose of the method. The review of the topic is extremely important since it is a matter of public interest world that brings into play issues and financial policies

Estudo da influência da aplicação do fluido de corte no torneamento da liga de alumínio AA7075

One of the ways to minimize the effects of unproductive time caused by tool wear can be achieved by introducing an efficient system of lubrication and cooling in the process. However, in the last decade the research had the goal to restrict the maximum use of refrigerants and / or lubricants in metal-mechanical production. The important factors that justify this procedure include the operational costs of production, ecological issues, and the legal requirements of environmental conservation and preservation of human health. The purpose of the proposed work is the study of machining by turning with the focus on the influence caused by the application of cutting fluid in several ways of application (abundant and MQF) and also by comparing the results obtained by machining without the presence of fluid . For this purpose, the turning tests are conducted using an aluminum alloy (AA 7075). The response variables to be analyzed were obtained from the roughness (Ra and Ry), the stresses presented (VB) and their progression in relation to the cutting length achieved, the type of chip formed, in addition to changes in the degree of finish (roughness) presented by the turned parts. The results of this study should provide more detailed information about the actual influence of cutting fluids in turning this alloy, which are characterized by high rates of deformation when the formation of damaging your chip machining and also the quality of surface generated. Therefore, it is expected to provide subsidies to promote the optimization of machining this alloy making the most of the role of cutting fluid

Condomínio residenciais fechados: um estudo de caso no município de Itu-SP

Since the middle of the XX century, observed a guided development in capitalism and globalization. In this context, a new way of thinking and producing dwellings, closed horizontal residential condominiums, with its beginnings in the United States. Currently, these also appear as a trend in Brazil. Their deployment has generated both social and spatial problems, since the production and consumption of urban space are given in different ways in different social classes. This process began in the 1970s and was unique to metropolitan areas until the 1980s, when it began to achieve medium-sized cities. Thus, highlighting some points, such as the production and consumption of urban space and the construction of condominiums in average Brazilian cities, this paper aims to describe and analyze the dynamics of residential condominiums in the city of Itu (SP)

Melhoria do nível de serviço no atendimento ao cliente por meio da estrutura direta de distribuição Transit Point

Increasingly competitive markets have driven the search for companies in many different ways to win and keep customers. The service level is basically the performance of companies in fulfilling the orders made, or how companies demonstrate to their clients efforts in their behalf. This work aims to solve the difficulties faced by a multinational company present in Brazil, in the distribution of its products in the category Ice Cream in order to improve the service level of their customers. Review the logistics network and concepts related to the distribution system of products is one of several ways to achieve this goal, as well as the use of IT and tools to assist in planning and programming of the physical distribution of products. In this study we used the concept of direct distribution system called Transit Point (TP). The TP provides at the same time, a strategy of rapid response, flexibility, low transportation costs and no inventory. A router - software capable of simulating the actual conditions experienced in the daily distribution - was used to assist in calculations. Results showed reductions of up to 47.5% in transportation costs and better conditions were provided in the distribution of products, positively impacting on service levels and in the maintenance of products quality, with a reduction of 1.6% of the total costs involve

Interface para classificação de dados por máquinas de vetores de suporte

In this project the Pattern Recognition Problem is approached with the Support Vector Machines (SVM) technique, a binary method of classification that provides the best solution separating the data in the better way with a hiperplan and an extension of the input space dimension, as a Machine Learning solution. The system aims to classify two classes of pixels chosen by the user in the interface in the interest selection phase and in the background selection phase, generating all the data to be used in the LibSVM library, a library that implements the SVM, illustrating the library operation in a casual way. The data provided by the interface is organized in three types, RGB (Red, Green and Blue color system), texture (calculated) or RGB + texture. At last the project showed successful results, where the classification of the image pixels was showed as been from one of the two classes, from the interest selection area or from the background selection area. The simplest user view of results classification is the RGB type of data arrange, because it’s the most concrete way of data acquisition

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

(Re)lendo os clássicos: trajetos de pesquisa

Neste artigo são abordados quatro momentos da história da pesquisa contemporânea sobre tradução e sua relevância para futuras pesquisas. Trata-se de uma (re)leitura de aspectos de obras que apontam para maneiras de se conduzir pesquisas na área que têm sido pouco examinados, possivelmente por terem sido ofuscados por tópicos de maior impacto tratados pelos autores. Berman é revisitado pela associação que faz entre crítica e história; Venuti, pela proposta de leitura sintomática; Lefevere e Bassnett, pela perspectiva de análise de traduções; e Arrojo, pelo questionamento da suposta neutralidade do sujeito que teoriza.

Um tempo para a literatura ou a vida entre o labirinto e a bússola

Since the priors, man has been trying to understand the concept of time. From myth to quantum physics, time is something that inspires reflections on our own lives. Do we exist in time or for time? Literature, a peculiar form of knowledge, deals with the experience of time in many ways. By avoiding categorizations, literature converges time and space in a dimension in which labyrinth and compass converge: at the reading time, in the reader’s space, in the universe of the book, where Cronos, Kairos, and their heir, by excellence, the literary word, constellate. In this way, in this essay, I discuss some aspects of the relationship between literature and time, or still, what literature can teach us about the time.

A formação do Professor de Línguas de uma Perspectiva Sociocultural

With the development of cognition studies and the awareness that teachers’ previous experiences, knowledge acquired in language teacher education programs and classroom experiences in different contexts shape the ways teachers think and construct their teaching practices, teacher education programs start to understand, from a sociocultural perspective, teachers’ learning as a dialogic process of knowledge co-construction, which is situated and emerges from practices and sociocultural contexts. Considering the relevance of this new perception, this article aims at presenting such theoretical perspective as well as its contributions to language teacher education research and teaching.
