Análise da estabilidade dimensional e resistência mecânica em bambu Guadua angustifolia pós-processos de tratamentos químicos e térmico

Nowadays, bamboo is being studied because of their strength properties according with their specific mass and speed of growth, which makes it an important alternative as a new resource that will help reduce pressure on forests and helpping them favoring the minimization of uncontrolled deforestation in many regions of Brazil. This study aimed, in general, to analyze physical and mechanical properties of the material with the divulgation of its potential for industrial application. To do so, in this research were determined in relation to the physical properties, moisture content, dimensional stability and the apparent densities and the mechanics and basic, just a tension parallel to grain, in order to observe the interference of various kinds of treatments (chemical, thermal and natural) on the strength and modulus of elasticity in this request. The species used was the Guadua angustifolia, a species native of Brazil. All tests were performed at Universidade Estadual Paulista - Campus Experimental Itapeva in the laboratory of Materials Properties. The methodology used for testing of moisture, density and tension parallel to grain were based on NBR 7190/1997 for the wood, and dimensional stability tests were based on much the same as in COPANT 462/1972 (South American) . The preservative treatments conducted followed the recommendation of each manufacturer. The values obtained in tests of physical properties were satisfactory especially with respect to density and dimensional stability analyzed by the coefficient of anisotropy, showed that, compared to wood, excellent quality for the shrinkage test, obtaining a coefficient of 1.2. With respect to parallel tensile tests to fibre results showed, in most cases, that test specimens with the presence of us have lower values of resistance and modulus of elasticity when compared with those without us. In the treatment of thermal-treatment there was an apparent treatment there was an apparent increase in...

Clonagem, expressão e purificação de três mutantes truncados da proteína LaRPA-1 de Leishmania amazonensis

A leishmaniose é uma doença que atinge milhões de pessoas no mundo e, de acordo com a FUNASA, está se espalhando por todas as regiões do Brasil. O tratamento desta zoonose é ineficaz, pois os fármacos utilizados apresentam muitos efeitos colaterais e colaboram com o aparecimento de parasitas e vetores resistentes. Portanto um maior conhecimento sobre a biologia molecular destes protozoários poderá facilitar o descobrimento de novas terapias e desenvolvimento de drogas antiparasitárias. O complexo telomérico é formado pela interação de DNA com proteínas, sendo que estas últimas podem também interagir entre si. A proteína RPA de eucariotos compreende um complexo trimérico subdividido em três subunidades. Este cumpre independentemente ou juntamente com outras proteínas diversas funções vitais para a célula, entre elas, auxiliar na manutenção dos telômeros e ajudar a recrutar a telomerase. Além disso, ela parece ser um dos principais componentes do complexo de proteínas que interagem com o terminal simples fita telomérico de protozoários tripanosomatídeos. Curiosamente, em Leishmania spp., as subunidades 2 e 3, ao contrário da subunidade 1 da RPA, não fazem parte do complexo telomérico. Portanto a LaRPA-1 pode apresentar comportamentos peculiares quando comparada a RPA dos outros eucariotos, e se tornar um importante alvo ao se estudar a biologia molecular do parasita. Este trabalho tem como objetivo clonar, expressar e purificar os três diferentes mutantes truncados da proteína LaRPA-1 para, futuramente, utilizar-se estas proteínas recombinantes como ligantes em ensaios de interação proteína:proteína, visando mapear possíveis sítios ou domínios na proteína LaRPA-1.O gene que codifica LaRPA-1 já encontrava-se clonado e sequenciado no laboratório de Telômeros da UNESP de Botucatu....(Resumo completo, clicar acesso eletrônico abaixo)

Estatuto do índio, direito indígena e impacto ambiental: aldeias Guarani do Jaraguá (SP)

In Brazil, there are three main codes that surround the issue of right or possession of various lands according to concepts of ownership or purchase. When it comes to indigenous issues in Brazil is difficult to say which legal code applies more fairly the native population of the country. In the case of the Indians who have their reserves near urban areas there is such a conflict of laws becomes more evident and takes even greater than in other regions of Brazil. As is the case in the indigenous villages of the District of Jaragua in Greater São Paulo, the Tekoá YTU and Tekoá Pyau. The two villages are located in northeastern São Paulo and currently are surrounded by continuous growth and disorderly city of Sao Paulo while their inhabitants fight to preserve the customs and traditions of the Guarani people. They prevail on the City Statute (2001), the Indian Statute (EDI) Environmental Laws and the National Council of Environment (CONAMA) and the Forestry Code, the latter solely because they are near the State Park Jaragua - area environmental preservation

Perfil e avaliação dos participantes de um curso de formação continuada em práticas educacionais inclusivas na modalidade a distância

This article analyses aspects related to a continuing education course about Inclusive and Special Education in the area of Mental Disabilities offered to 20 (twenty) groups of teachers by the Ministry of Education. The Distance Course was offered in different regions of Brazil with a 180 (a hundred and eighty) hours workload. The research included the profi le of the participants, an evaluation of the course by the participants and the analysis of the dropout causes. The aspects of the course under evaluation received a positive evaluation by most of the participants. The most frequent reason for the dropout rates include participants’ limitations in terms of meeting deadlines, personal reasons and diffi culties in using computers. It was concluded that Distance Education seems to be a relevant tool for the acquisition of knowledge about inclusive practice.

Relações de interferência entre plantas daninhas e a cultura do grão-de-bico

The grains of chickpea consumed in Brazil are almost entirely imported. Considering that chickpeas presents conditions to be cultivated in some regions of Brazil, this study aimed to study interference of six weed plants (Amaranthus viridis, Bidens pilosa, Raphanus raphanistrum, Cyperus rotundus, Digitaria nuda and Eleusine indica) on the vegetative development of chickpeas. Thus, we evaluated the shoot length, number of leaves, leaf area, chlorophyll content and dry weight of leaves, stem and root of chickpeas. We observed a significant interference on the chickpeas'development in coexistence with weeds. Among the weeds, D. nuda, E. indica and A. viridis were the most aggressive, highlighting the need for early control of weeds when in cultivation of chickpeas in areas with a history of high density of these weeds. The leaf area of chickpeas was the most affected trait by the coexistence with weeds, affecting the development of the crop.

Plano de carreira, cargos e salários: ferramenta favorável à valorização dos recursos humanos em saúde pública

Human recourses on Brazilian Health System (SUS) are important social points because on this form the State can guarantee the health like a right of Brazilian population, based on National Constitution Dictates. The Plan of Offices, Careers and Salaries (PCCS) is an administrative tool that should be elaborated to attendance objectives of organization. It maintain the satisfaction level of workers, with a politic of Human Recourses that allows its development and so, can get higher productivity, efficiency and objectivity of services rendered at community. The aim of this study is to contextualize the PCCS like an instrument of People Management to guide and incentive one of forms to turn no precarious the work force of Public System Dental Professionals in SUS. For them, it was realized a literature review, and official documents of Health Ministry were consulted, like governmental decrees, laws, health conference written report. It was possible to verify that, although there is legal basement on the use of PCCS-SUS by Brazilian cities like a tool to attract and maintain dental surgeon developing his profession on SUS, is often the absence of valorization of this professional, and this situation no allows his exclusive dedication at health public services. Precarious work in Dentistry is still observed on many regions of Brazil.

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

Capacidade de suporte de carga e densidade do solo em áreas de plantio direto com e sem escarificação

No-till has been used in many different regions of Brazil. However, depending on the location and intensity of machinery traffic, this has caused the problem of soil compaction and many producers are scarification the land as a solution to break through the layer that is restricting plant growth. The objective of this study was to evaluate the influence of scarification (0.30 m) in the physical properties of a dystrophic Alfisol comparing the results with a non-scarified contiguous area; both were previously conducted using no-till. The density and pressure of pre-consolidation were sampled in two areas of non-tillage, one with chiseling (PDCE) and one without (PDSE) by using the UMAS -Mobile Soil Sampling Unit built by NEMPA – Agroforestry Machinery and Tire Testing Center/FCA / UNESP, Botucatu ,SP. The UMAS is equipped with GPS which allows the samples to be georeferenced. The samples were evaluated in the laboratory through the collection of standardized rings. Sampling was performed at a dimension of 15 x 50 m, with 160 rings being collected. The samples containing rings which were used in determining the density and also for testing the consolidometer, were collected from the layers of 0 to 0.10 m, 0.10 to 0.20 m, 0.20 to 0.30 0.30 to I 0.40 m. For the odometer test the undisturbed sample rings were used in obtaining the load bearing capacity of the soil. The soil management adopted provided a decrease in soil density using no-tillage with scarification depths from 0.0 to 0.10 0.10 to 0.20 m while the other depths did not show any decrease. The pre-consolidation pressure in combination with soil aggregate resistance identified that the management process PDCE within all layers was subjected to water content reliability regarding a greater load bearing capacity of the soil. For the PDSE that only was possible in the 0 to 0.10 m, showing greater consolidation of this layer.
