Remoção de N-amoniacal em baixas concentrações de oxigênio dissolvido a partir do efluente de frigorífico bovino

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD

Dipolo e escoamento uniforme: escoamento em torno de um cilindro circular

The study of movements of ideals fluids is more simple that the viscous fluids because do not have the presence of tension of shear. The normal tensions are the one that must be considered in this analysis. The theory corresponding to these flows is the same used in other fields of the physics called Theory of Potentials Fields, which the vector identity is fundamental. Any flow into irrotational (null vorticity) physically possibly has a current function and a potential of velocity that satisfied the equation of Laplace. Reciprocally, any solution of equation of Laplace represents a current function or a potential of velocity of a flow into physically possible. Once the equation of Laplace is linear, the addiction of any numbers of solutions is also a solution. So, several potentials flows into can be constructed superposing configurations of elementary flows into. The purpose of the superposition of elementary flows into is a production of similar configurations to those of practical interest. The combination of mathematical elegancy with utility in the potential flow into attracted many for its study. Some of the most famous mathematician of history studied the theory and application of “hydrodynamic”, how was called the potential fluid into before 1900

Política monetária do Banco Central do Brasil: uma análise sobre a inserção e a eficácia do regime de metas de inflação durante os anos de 1999-2010

O capítulo 1 trará as mais importantes correntes teóricas sobre inflação, desde meados do século XX até o fim deste século. Também será demonstrado o pensamento da corrente Cepalina, mais especificamente os autores brasileiros que escrevem acerca da inflação que era observada no período (década de 1980). Assim, chegaremos a como se é formulado o regime de metas de inflação. Após isso, foi efetuada uma cronologia desde a implementação do plano real no Brasil até a inserção do regime de metas de inflação em 1999. O capítulo 2 tem como seu conteúdo principal abordar a eficácia do regime de metas de inflação. Para isso, trará um modelo estatístico, mostrando e interpretando os resultados obtidos. Após isso, o capítulo trará um panorama geral de como evoluiu o regime de metas de inflação no Brasil nos anos em que o trabalho se situa. Na conclusão, serão trazidos os principais questionamentos do trabalho, bem como as respostas encontradas para este e os eventuais desafios que um aprofundamento maior poderá acarretar

Escoamento da produção de café: uma projeção de logística

This paper seeks to show which impacts there are of the combined use of different modal for the coffee’s outflow. Nowadays is used, almost exclusively, the roadway to transport. How-ever, for this product with low added value, the types of transports best suited, in the litera-ture, are the railway and waterway. For this, is describe the development and spread of coffee throughout Brazil. Subsequently, is calculate the current cost of transporting two producing regions (Minas Gerais and Rondônia), using for that information about the freight, the social cost, and the level of losses along the way. After that is projected costs if utilizes the multi-modal model, when considering the same cost parameters used for the current model. Here-after, an analysis is made of the obtained cost, speed, consistency, capacity, availability and frequency of each transport model. Therefore, note that the multi-modal system is more ef-ficient and economical than current, based on transport by road

A lei e a força no regime militar brasileiro: da proscrição da frente ampla à edição do Ato Institucional n. 5

This article analyses the Brazilian political process in the period between the beginning of the government of general Arthur da Costa e Silva in March 15, 1967 and the edition of the Institutional Act No. 5 (December 13, 1968). Through the analysis of the key moments in this context, seeks to qualify the actions of the main political players in terms of their goals and strategies and assess the impact that they had on the production of authoritarian legislation.

O regime de metas de inflação no Brasil: uma análise empírica do IPCA

Inflation targeting regime is a monetary policy adopted by several countries in the 1990s, Brazil being among them, which adopted it in 1999 after a currency crisis. With a theoretical framework inspired by the new-classical theory, this regime is adopted by countries attempting to achieve price stability and it brings the prior announcement of a numerical target for inflation as a key feature. The present work aims at discussing the use of IPCA (Consumer Price Index) as a measuring index for Brazil's inflation after briefly explain the theoretical basis of the IT regime.

In-Office dental bleaching efficacy assessment in function of the light exposure regime by digital colometric reflectance spectroscopy

In-office dental bleaching has been subject of several studies. Generally those studies quantify through visual analysis, the shade reduction of the teeth submitted to different bleaching protocols (light sources, bleaching agent concentrations and irradiation time). The objective of this work is the determination of the influence of four irradiation protocols on the obtainment of better aesthetic results using a colorimetric spectrophotometer that quantifies color changes in each situation imposed. Forty bovine incisors were selected in function of similar anatomic characteristics; a concentrated coffee solution was used to stain the teeth. A commercial spectrophotometer was used to measure the color changes during evolution of the experiment (stain and bleaching phases) and the obtained data was analyzed by the ANOVA test. The obtained data showed the evolution of teeth color during the staining period, as well as, the color reduction that each bleaching protocol achieved. Based on our findings it is possible to conclude that bleaching protocols with larger irradiation periods did not showed significant differences when compared with shorter irradiation protocols, in that way the use of protocols with 30 min or more of consecutive irradiation are not clinically justified and also can cause several side effects.

Identidade psicossocial dos adolescentes no regime de internato na Educação Agrícola

Psychosocial Identity of the adolescents in boarding school system in the agricultural education Abstract: This article is the result of a research where we try to study and to understand the psychosocial identity of adolescents undergoing boarding. We discussed the issue of boarding school in literature and notes about adolescence in various psychological approaches. Research strategies were interviews, and focus group reports. We conclude that, even with the difficulties students believe that the promising future can only be achieved through technical training, which would enable them not only to acquire a knowledge, but also as a way to gain access to a better-paying job. A better understanding of the surrounding reality allows us to subsidize various professional institutions also adopt boarding as an option to stay.
