A teoria, a prática, o professor e a educação ambiental: algumas reflexões

The acceleration of economic and scientific development caused by the production system and mechanistic science, have created new power structures and new political and social problems, including environmental ones, consolidating a period of widespread crisis in different spheres of society. In this context, reflection about the major causes of environmental problems is necessary in the field of environmental education. Therefore, considering that the current environmental crisis is directly related to the mode and the devices of production of the capitalist system, initiatives on environmental education should reflect, from a historical and dialectical process, on what is advocated by capitalist society. Considering the various theoretical-practical concepts and approaches in environmental education, the principles of Critical Environmental Education can provide conditions to confront the structural crisis that we are facing, through the educational process. It is a political process of reflection and critical appropriation of knowledge, attitudes, values and behaviors that aims to contribute to build a sustainable society from the social and environmental points of view. We intend to articulate it through the theoretical formulations of Historical-Critical Pedagogy with the purpose of presenting a reflection that may contribute to a pedagogic response to environmental issues, especially regarding the formation of teachers who develop projects in schools. Thus, this present study intends to highlight the contributions of the philosophy of praxis in the formation of environmental educators, grounded in theoretical aspects of Critical Environmental Education.

Fernando Henrique Cardoso e a dependência da região Amazônica

The goal for this research is to analyse the thinking of Fernando Henrique Cardoso (FHC), to understand his vision about underdevelopment nations and his teses about dependence, in order to comprehend its consequences of his the thinking for the Brazil and primarily to the brazilian Amazon region. Considering that the penetration geographical on Amazon and the history of the region make part of the totality of the process on expansion of the capitalism, in his form, function, rythm and volume of the accumulation occurred also in the other regions of the Brazil (and abroad), we have to study it in this way, showing that is a totality. Then to understand the actions of Cardoso as president, mainly on this region. Bringing this discussion to the social function of the corporations and the many faces of underdevelopment

Sitios Assistenciais em Unidade de Terapia Intensiva e Relação do Nursing Activities Score com a Infecção Hospitalar

The Patient Classification System has become essential concerning to the practice in management and care from a nurse. This study analyzed the implementation of Assistance Sites in an intensive care unit for adults as a way of organization and classification of patients, as well as the impact of this process on the quality of care according to the Nursing Activities Score and the relation with the Hospital Infection. This is a quantitative, prospective, descriptive and transversal study. The data collection was realized from July until October 2010. The sample was consisted of 214 patients, mostly male, neurosurgical and with a mid age of 57 years. The NAS was on the average of 71.72%. Regarding the Hospital Infection before and after implantation, there was a reduction in the rates of pneumonia. However, the nursing workload remained the same. Moreover, It was evident the importance of using the Nursing Activities Score and the implementation of new ways for classification of patients to improve the organization of the care.

Propriedades de pasta e térmicas de misturas instantâneas de farinha de soja, fécula e farelo de mandioca

The application of extrusion technology in the food industry has enabled the development of new commercial products of fast preparation, and maintaining the nutritional characteristics after the process. During this process there are changes in raw material due to the action of temperature, humidity and mechanical friction resulting in a modified product which can be used in various industrial applications. This work aimed to evaluate the effect of the composition of the raw material and operating conditions of the extrusion process on the properties of paste and thermal properties in the development of a functional instant flour of cassava and soybean. The results showed significant effects of all operating parameters on the rheological properties studied. The extruded flours showed no residual gelatinization enthalpy, suggesting that the starch in the samples was gelatinized. The experimental conditions of the smallest percentages of cassava residue (10%) and high soybean flour (25%) mixed with cassava starch, extrusion temperature of 75ºC and low screw speed (170rpm) leads to obtain instant flour with desirable characteristics.

Torneamento da liga de alumínio da classe 6005 utilizando ferramenta cerâmica

Machining processes are one of the most important manufacturing processes in the modern world. In these processes, there are many elements which will influence in the final result of the machined part. Among them, the tools are the principal factor of the rising cost, because its global influence on the process. In aeronautical industries, this can be more evidenced due the need to machining several alloys, between them, aluminum alloys. These alloys have to demonstrate a specific surface finishing to be used in aircraft's fuselage. This kind of industry is one of the segments which is still rising in Brazil, and they are looking viable alternatives in the manufacturing processes of materials, due the need to produce more and more parts and equipment, with costs increasingly reduced. The purpose of this project is the development of a ceramic with differentiated properties. The ceramics were developed using a pre-sintering at 1200 °C, with posterior sintering at 1600°C, and subjected to dry turning process on aluminum alloy 6005. The characterizations showed that ceramics presented with toughness on the center of 1700 MPa and on the surface of 1950 MPa, density 98,5 ±0,14. g/cm³. Ceramics were grinded and faceted, according to ISO standard 1832, and subjected to turning tests in a ROMI lathe brand, model GL240M, using cutting speeds of 500, 800 and 1000 m/min with different feed rates. The machining results showed low occurrence of flank wear to all cutting speeds, and better surface finishing average values of Ra = 0,4935 μm and Rt = 8,112 μm. In general, it could be seen that the tool presents important potential to machining 6005 alloy, and that the use of correct parameters can decrease and/or eliminate subsequent processes, providing important reductions in costs related to the machining processes

Effect of steeping conditions (sulfur dioxide, lactic acid, and temperature) on starch yield, starch quality, and germ quality from the Intermittent Milling and Dynamic Steeping process (IMDS) for a Brazilian corn hybrid

Effect of lactic acid, SO2, temperature, and their interactions were assessed on the dynamic steeping of a Brazilian dent corn (hybrid XL 606) to determine the ideal relationship among these variables to improve the wet-milling process for starch and corn by-products production. A 2x2x3 factorial experimental design was used with SO2 levels of 0.05 and 0.1% (w/v), lactic acid levels of 0 and 0.5% (v/v), and temperatures of 52, 60, and 68degreesC. Starch yield was used as deciding factor to choose the best treatment. Lactic acid added in the steep solution improved the starch yield by an average of 5.6 percentage points. SO2 was more available to break down the structural protein network at 0.1% than at the 0.05% level. Starch-gluten separation was difficult at 68degreesC. The lactic acid and SO2 concentrations and steeping temperatures for better starch recovery were 0.5, 0.1, and 52degreesC, respectively. The Intermittent Milling and Dynamic Steeping (IMDS) process produced, on average, 1.4% more starch than the conventional 36- hr steeping process. Protein in starch, oil content in germ, and germ damage were used as quality factors. Total steep time can be reduced from 36 hr for conventional wet-milling to 8 hr for the IMDS process.
