Cursos superiores de tecnologia: igualdade jurídica e dualidade na escola

Since the 1990s, higher education technology courses in Brazil have greatly expanded the offer of courses and places. However, the high dropout rates presented in these courses led to a research in order to uncover the factors that lead students to dropout. Through literature review and desk research, this study makes a historical analysis of how professional education is conducted in Brazil. This paper seeks to demonstrate that the implementation of public policies for professional education exacerbates the school’s duality. However, such duality generates contradictions between subjective and objective issues produced by the ideology disseminated by public policies and government actions in relation to vocational education. These contradictions end up unveiling the social inferiority of vocational education and discourage students from remaining in the courses. The legal equality between educational levels seeks to mediate the emergence of these contradictions. However, despite legal equality, social equality is not achieved in the implementation of public policies, leading to a high dropout rate.

Foraminíferos em um transecto de manguezal da Ilha do Cardoso (SP): distribuição em função da frequência de inundação e modelos para reconstruções paleoambientais no setor de petróleo & gás

O estudo do conteúdo de foraminíferos de 8 amostras de sedimentos superficiais coletados em manguezal do norte da Ilha do Cardoso, sul do Estado de São Paulo, no verão (período chuvoso) de 2001, ao longo de um transecto no sentido da Baía de Trapandé para o interior, revelou dois segmentos distintos: a) uma planície inferior lamosa, com menor tempo de exposição sub-aérea e maior diversidade específica, dominada por Ammotiumcassis, A.salsum, Arenoparrella mexicana e Trochamminainflata, com abundância expressiva de Caroniaexilis na parte mais baixa e de Miliammina fusca na parte mais alta; b) uma planície superior arenosa, com maior tempo de exposição sub-aérea e menor diversidade, dominada por M. fusca e com abundância expressiva de T. inflatana parte mais baixa. Os sedimentos investigados são colonizados por foraminíferos exclusivamente aglutinantes, representados por 21 espécies de 16 gêneros. Dados de abundância relativa, riqueza, diversidade e equitatividade das espécies ao longo do transecto são apresentados, bem como os valores de salinidade, pH, oxigênio dissolvido e temperatura, medidos a partir da água intersticial dos sedimentos no momento da coleta das amostras. São feitas comparações com um estudo anterior, similar, que focalizou amostras coletadas, nos mesmos pontos, no inverno (período seco) de 2002. Os resultados obtidos interessam às análises de sistemas estuarinos modernos e antigos, bem como a projetos envolvidos com o diagnóstico do estado de conservação de áreas litorâneas, sendo úteis ao Setor de Petróleo e Gás

Produção e estudo da imobilização de lipases fúngicas visando à obtenção enzimática de biodiesel

A atual demanda por produtos alternativos que substituam os combustíveis fósseis, causadores de alto impacto ambiental negativo, tem fomentado pesquisas em diferentes áreas como o emprego de lipases microbianas como biocatalisadores no setor de energia. Como mais uma forma de busca por tecnologias limpas, há também interesse no aproveitamento de resíduos agroindustriais. Nessa vertente, o Brasil como grande produtor agrícola se destaca na geração de subprodutos como o bagaço de cana-de-açúcar. Uma alternativa mais ecológica para atender a essa demanda é a produção de biodiesel, produzido a partir da transesterificação de triglicerídeos de origem animal ou vegetal, tendo como características não ser tóxico, ser biodegradável e fonte renovável de energia. As lipases são enzimas que aceleram reações de hidrólise e síntese, podendo ser obtidas de microorganismos por meio de processos de fermentação em estado sólido, porém com alta demanda de recursos financeiros para sua produção. Hoje em dia, o que está em alta na indústria de tecnologia com enzimas é a utilização de resíduos agroindustriais e processos de imobilização com o intuito de diminuir os gastos em sua produção, um dos gargalos para seu uso mais amplo. Neste trabalho foi analisada a viabilidade do uso do bagaço de cana-de-açúcar misturado a farelos de soja ou trigo como meios de cultivo em fermentação semi-sólida, assim como a melhor concentração de umidade para o desenvolvimento de lipases pelo microorganismos estudados. Foi testada também a viabilidade de imobilização das lipases produzidas em suporte de celite

Caracterização e origem da composição química da incrustação e simulação de cenários de perda de energia em setor da rede de abastecimento de água da cidade de Rio Claro - SP

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

Mapeamento do processo de originação de etanol em uma empresa do setor de distribuição de combustíveis

The market segment of fuel distribution composes an important role in the development of Brazil’s industry and economy. However, it is a sector with intense competitiveness, especially in relation to ethanol. The search for competitive advantage and greater strength to the business are, therefore, of high relevance in this context, in which the concepts of Business Process Management has become more visible. Process Mapping, one of these concepts, has proven “TO BE”a strategic tool for companies which believe in flattening the structure and in the potential benefits that the improvement of its processes can provide. Thus, this work aims to map the process of Ethanol Origination of a company engaged in the distribution of this and other fuel products, and other niche markets. It was understood and designed the macro-process aforementioned and identified failures in subprocess related to it. After applying the method to select priority problems, using risk assessment criteria, five subprocess were identified to receive special action, which consisted in seeking improvements with those involved in the process, in representing its current and ideal models and in defining each department’s responsibilities for the activities in the subprocess proposed form. Thus, it is expected to mitigate mainly two negative effects found in the business: employee’s work overload and company's financial exposure

Técnicas associadas à biotecnologia da reprodução para minimizar os efeitos do estresse térmico e aumentar a fertilidade em vacas leiteiras de alta produção

The dairy sector has undergone considerable economic losses due to low fertility rates due to adverse effects of heat stress on reproduction of cows. Genetic selection for increased production, coupled with the expanding dairy to tropical areas of the planet, and global warming has further aggravated the problem of heat stress. The effects of heat stress are multifactorial and act directly or indirectly at various levels of reproductive tissues, resulting in low fertility of cows, which in practice, results in reduced reproductive efficiency in the property, reducing the producers’ profit. Some strategies related to breeding biotechnology such as fixed-time artificial insemination, embryo transfer and use of BST, can minimize these effects and improve the reproductive efficiency of the herd

Análise de algoritmos computacionais utilizados em sistemas de planejamento de braquiterapia de alta taxa de dose: estudo comparativo com o Código MCNP-5C

In radiotherapy, computational systems are used for radiation dose determination in the treatment’s volume and radiometric parameters quality analysis of equipment and field irradiated. Due to the increasing technological advancement, several research has been performed in brachytherapy for different computational algorithms development which may be incorporated to treatment planning systems, providing greater accuracy and confidence in the dose calculation. Informatics and information technology fields undergo constant updating and refinement, allowing the use Monte Carlo Method to simulate brachytherapy source dose distribution. The methodology formalization employed to dosimetric analysis is based mainly in the American Association of Physicists in Medicine (AAPM) studies, by Task Group nº 43 (TG-43) and protocols aimed at dosimetry of these radiation sources types. This work aims to analyze the feasibility of using the MCNP-5C (Monte Carlo N-Particle) code to obtain radiometric parameters of brachytherapy sources and so to study the radiation dose variation in the treatment planning. Simulations were performed for the radiation dose variation in the source plan and determined the dosimetric parameters required by TG-43 formalism for the characterization of the two high dose rate iridium-192 sources. The calculated values were compared with the presents in the literature, which were obtained with different Monte Carlo simulations codes. The results showed excellent consistency with the compared codes, enhancing MCNP-5C code the capacity and viability in the sources dosimetry employed in HDR brachytherapy. The method employed may suggest a possible incorporation of this code in the treatment planning systems provided by manufactures together with the equipment, since besides reducing acquisition cost, it can also make the used computational routines more comprehensive, facilitating the brachytherapy ...

O setor sucroalcooleiro no Pontal do Paranapanema: uma análise a partir do licenciamento ambiental

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

A territorialização do setor sucroalcooleiro no Pontal do Paranapanema: estudo de caso do município de Martinópolis - SP

The sugarcane agribusiness has expanded by Brazil in recent years, especially with government incentives, which funded the construction and expansion of distilleries and sugar mills and alcohol throughout the national territory, as well as the expansion of the cultivation of sugarcane sugar. The state of São Paulo is the main focus of expansion in the sector, and its municipalities impacted significantly. The Pontal do Paranapanema is one of the last frontiers of cane sugar in the state, so that the culture has brought transformations mainly from 2003. Thus, we take the case of the municipality of Martinópolis analysis, which investigated some transformations in economic dynamics from 2004, the year he began the deployment of Plant Athena. For this, we conducted interviews with several subjects and analyzed statistical data from IBGE, LUPA, MAPA and CANASAT. Aware that these changes are limited to the capitalist market economy, we analyze the benefits and disadvantages brought by the activity of the plant for the population as part of economic growth characteristic of this scenario, taking it to the very prospect of local subjects. Alongside this growth, all other forms of inequality and exploitation of surplus value also grow which is not understood or perceived by residents. Hence the need to confront views and discourses on development promoted by the alcohol sector
