CARACTERÍSTICAS DAS ROCHAS DA FORMAÇÃO CORUMBATAÍ UTILIZADAS NA INDÚSTRIA DE REVESTIMENTO CERÂMICO.

A Formação Corumbataí é atualmente utilizada com sucesso pela indústria de revestimento cerâmico no pólo de cerâmica de Santa Gertrudes. Este engloba os municípios de Santa Gertrudes, Rio Claro, Cordeirópolis, Limeira, Piracicaba e Araras. De acordo com os estudos geológicos realizados, as argilas da Formação Corumbataí foram divididas em cinco litofácies cerâmicas, sendo elas: maciça, laminada, intercalada I, intercalada II e alterada. De acordo com suas características químicas, são consideradas como argilas com teores médios de elementos fundentes, com os valores da soma dos óxidos alcalinos (Na2O + K2O) variando de 2,9% na litofácies alterada até valores de 4,3% na litofácies intercalada I. Os argilominerais predominantes são a illita e a caulinita (presentes em todas as litofácies), além da montmorillonita que ocorre com freqüência nas litofácies intercalada I e II e laminada. Outros minerais importantes são: quartzo, feldspato do tipo albita, hematita e calcita. Os resultados cerâmicos possibilitaram enquadrar as litofácies cerâmicas dentro do Grupo BIIb na Classificação de Revestimentos Cerâmicos (BII – valores de resistência à flexão da ordem de 180-300 Kgf/cm2; b – valores de absorção de água (Abs) de 6 a 10%), porém, alguns valores de Abs ficaram acima de 10% nas litofácies intercalada I, intercalada II e na alterada.

A Consciência Corporal e a Formação de Professores de Pré-Escola e Ensino Básico

O tema consciência corporal ocupa um espaço restrito na área da Educação. Normalmente o associamos às atividades físicas sem saber bem o seu significado em um sentido mais amplo. Propomos, a partir deste ensaio, a reflexão sobre a importância do desenvolvimento da consciência corporal, tanto no nível existencial, quanto no nível da aprendizagem em si. Pretendemos também demonstrar o papel do professor neste processo e a importância de ele trabalhar a própria consciência. corporal.

Integração básico-clínica no internato médico: Psiquiatria e Farmacologia

This study quantifies fifth year medical students' knowledge after their participation in a basic clinical integration activity of psychiatry and pharmacology and investigates their opinions on the importance of the activity. A quali-quantitative study was performed using pre- and post-test assessment (multiple choice) and linguistic content analysis using the Discourse of the Collective Subject (DCS) technique. A significant increase in the percentage of correct answers in the post-test assessment was found compared to pre-test (p <0.001). The central ideas obtained from the DCS content analysis were: very relevant activity; expansion of the activity to other internships; difficulty in basic disciplines; application of cognitive assessment; and teacher's active participation in discussions. These results suggest that integration between pharmacology and the practical intern activities in psychiatry allowed pharmacological concepts to be broadened, rendering the learning meaningful. Although students identified the need for better organization of the activity, its the level of acceptance was verbalised through the suggestion that it could be extended to the other fifth year internships.

Degradação de membrana impermeabilizante de polietileno de alta densidade usada em tanques de armazenamento de vinhaça

High-density polyethylene (HDPE) water-proof membranes are used as coatings in vinasse (leachate from sugar cane) storage tanks. The leachate is pumped into the tanks at temperatures of 80-90 °C. Due to these high temperatures and acidity of the waste, these membranes can be degraded, cracked and then loose the function for which they have been designed. This may cause contamination of the soil and groundwater. This study evaluated the effect of vinasse in HDPE membranes after 4 months of exposure in a controlled environment. An aggressive, alkaline pH liquid (sodium hydroxide) was also used. The objective was to evaluate the membrane resistance in contact with acidic and alkaline residues. Physical and mechanical tests, measurement of the carbon black content and thermo gravimetric analysis (TGA) were used to determine degradation of polymer membranes after chemical immersion. While sodium hydroxide resulted caused only minor changes in the physical properties, vinasse induced a thickness change of 7.8%. With immersion in vinasse, an average decrease in strength and deformability (yield) of 34% and 23.5% were measured, respectively. The stiffness increased by 7.8% (average) and the tear strength decreased by 2.7% (average).

Biofertilizante bovino, cobertura morta e revestimento lateral dos sulcos na produção de pimentão

The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

O saber fazer docente na educação para a sexualidade em Coimbra, Portugal: a realidade de 02 escolas de ensino básico

The research addresses the teacher know-how in relation to how it is crafted to education for sexuality in two public schools in Coimbra - Portugal, with teachers from different areas of the 3rd cycle of basic education (humanities, sciences and biological sciences), which corresponds to the Elementary School II in Brazil. It will be based on law 60/2009 of August 6, regulated by Decree 196-A of April 9, 2010 of the Ministry of Education - Portugal, which establishes the implementation of sexual education in primary and secondary schools across the country. This research is funded by FAPESP - Research Support Fund of the State of São Paulo, process number 2011/12902-3. The research was based on a qualitative approach, conducting case studies and using semistructured interviews for data collection. The performance of the topic of sexuality and gender relations at Portuguese’s classroom aims to provide young people the opportunity to exercise their sexuality in a responsible, healthy and pleasurable way. The law seeks to ensure that this work is established in the Portuguese school effectively. Therefore, the trajectory of teachers formation (initial or continuing) will also be a focus of this research, to understand how and where it is built and how they act in their daily classroom practices, with their students the sexuality and gender relations

Interação entre universidade e escola de ensino básico: um panorama dos projetos de extensão do Instituto de Biociências - Botucatu

A extensão é compreendida como uma interação entre a Universidade e a comunidade na qual está inserida e como uma via de mão dupla onde a Universidade leva conhecimentos e/ou assistência à comunidade e recebe dela influxos positivos e reais necessidades, ou seja, constitui-se uma relação de troca de conhecimentos. As atividades de extensão desenvolvidas no Instituto de Biociências (IB) da UNESP - Campus Botucatu, por meio de projetos, são diversificadas quanto ao público alvo, quanto ao local de realização e também quanto aos objetivos.

Thus , this work discuss the durability of mixed mortar lining , made with waste from the process Kraft pulp production , known as dregs and grits , in partial replacement of sand. Tests were conducted to simulate conditions as adverse environments of constant heat and fire, with the aim of analyzing the behavior of mortar mixed matched the behavior of standard mortar

Revestimento interno de tubulação por um processo de centrifugação utilizando resina éster-vinílica com adição de cargas

Being the corrosion one of the great problems facing the industry today, specifically the internal corrosion of pipes in chemical and petrochemical industries, hence this work proposes a new type of internal coating in order to avoid fouling and decrease the pressure loss in the flow. For this, we use a composition of vinyl ester resins and manometric loads, which after cleaning and preparation of the internal surface of the tube will be applied through a process of centrifugation, adjusted by a lathe. After curing the resin, a test of roughness will be realized in order to analyze the reduction of friction factor and thus be able to conclude whether there was a significant decrease in pressure drop. With test results in hand, we hope to obtain a coating that meets most of the properties required by the industry and to provide a reduction in operating costs and a visible improvement in the conditions of use of the pipe
