Tradução, adaptação e validação da versão brasileira do questionário utian quality of life (uqol) para avaliação da qualidade de vida no climatério

The present study had as objective translates, to do equivalence and validation of the Utian Quality of Life (UQOL) for the Brazilian population through methods internationally accepted, in which the original questionnaire was translated for the Portuguese by three teachers and the consensual version was translated back for English by two American teachers (back translation). A multidisciplinary committee evaluated all versions and the final version in Portuguese was applied to climacteric women for the process of adaptation. Validation of the instrument was performed by measuring the reliability and validity properties. Construct validity was examined through the comparison between UQOL and the general measuring scale of quality of life Short Form-36 (SF-36). The final version of translation process was easily recognized by the target population, that didn't tell understanding problems. The results obtained for the reliability intra and interobserver showed significant agreement in all of the subjects. The construct validity was obtained through correlations statistically significant among the domains occupational, health and emotional of UQOL with the SF-36 domains. For the exploratory factorial analysis, it was verified that three factors explain 60% of the total variance of the data, the present study allowed concluding that UQOL was appropriately translated and adapted for applicability in Brazil, presenting high reliability and validity. In that way, the executed project provided the involvement of different areas as gynecology, psychology and physiotherapy (interdisciplinary). Thus, this instrument can be included and used in Brazilian studies to assessment the quality of life during the climacteric years

Selectivity of the plant growth regulators trinexapac-ethyl and sulfometuron-methyl to cultivated species

The aerial spraying of plant ripeners on sugar cane (Saccharum officinarum L.) crops causes often the contamination of neighboring areas, which subsidizes formal complaints from the neighbors. These contaminations are due to spraying taking place during inadequate environmental conditions or from technical mistakes during the application. One of the most important causes of this contamination is the susceptibility of the species being cultivated surrounding sugar cane. In order to evaluate the effects of sugar cane plant ripeners trinexapac-ethyl and sulfometuron-methyl on peanuts, cotton, potato, coffee, citrus, beans, sunflower, cassava, rubber, soybean, and grapes, eleven experiments - one for each species - were carried out from May 2009 to Jan. 2010. The field experiment was set according to a completely random design with five treatments and four replications. Just before or during flowering, a single treatment of trinexapac-ethyl at 100 or 200 g ha-1 and sulfometuron-methyl at 7.5 or 15 g ha-1 was applied to plants. A control treatment (plants not treated) for each species was part of each experiment. Trinexapac, at the doses of 100 and 200 g ha-1, showed selectivity to peanuts, cotton, potato, coffee, citrus, sunflower, cassava, rubber, soybean, and grape. At the lowest dose (100 g ha-1), it was selective for bean. Sulfometuron, at the dose of 7.5 g ha-1, was selective for peanuts and, at the two studied doses (7.5 and 15 g ha-1), it was selective for coffee, citrus, cassava, and rubber.

Caracterização morfológica de frutos e sementes e desenvolvimento pós-seminal de monjoleiro (Acacia polyphylla DC.)

Acacia polyphylla DC. é uma espécie arbórea, característica dos estádios iniciais da sucessão secundária, de ocorrência natural no Brasil. Pertence à família Leguminosae-Mimosoideae, sendo recomendada em programas de reflorestamento misto, recuperação de áreas degradadas e manejo de fragmentos florestais. Entretanto, não foi encontrado nenhuma referência que fizesse menção aos aspectos químicos e morfológicos das sementes, bem como, aos aspectos do desenvolvimento pós-seminal desta espécie. Assim sendo, o presente trabalho objetivou caracterizar morfologicamente e ilustrar frutos e sementes, quantificar alguns componentes químicos presentes nas sementes e descrever as diferentes fases do desenvolvimento pós-seminal. Para tanto, foram realizadas descrições associadas às estruturas externa e interna das sementes. As descrições morfológicas dos frutos e das sementes foram efetuadas em relação a forma, ao tamanho, a superfície, a micrópila e a forma e a localização do embrião. Para a descrição morfológica das plântulas, as sementes foram colocadas para germinar em meio de cultura Murashige & Skoog reduzido à metade da concentração e incubadas a temperatura de 25ºC, sendo descritas e ilustradas as plântulas normais e anormais. O fruto é uma vagem deiscente contendo de oito a 16 sementes achatadas, de tegumento testal, embrião axial e invaginado. A germinação das sementes é epígea e as plântulas fanerocotiledonares.

Produção de metano entérico em pastagens tropicais

Na presente revisão, buscou-se apresentar os principais impactos ambientais causados pela pecuária, sobretudo, em relação às emissões de gases efeito estufa (GEE). Além disso, buscou-se apresentar possíveis formas de mitigar essas externalidades. A criação de bovinos, no Brasil, acontece de forma extensiva, muitas vezes em áreas com pastagem degradada e, portanto, de baixa produtividade. Isso possibilita à atividade uma oportunidade de redução do impacto causado ao meio ambiente, uma vez que ações tomadas, no sentido de melhorar o rendimento animal, devem resultar em um menor consumo de recursos naturais (terra e água) e maior eficiência do sistema digestivo animal. Os principais problemas apontados pelos pesquisadores, no que tange à pecuária extensiva, são o metano emitido pela fermentação entérica dos ruminantes, o óxido nitroso emitido pelos dejetos dos animais em pastejo e o dióxido de carbono trocado pelo solo e vegetação. Muitos fatores influenciam a produção de CH4 entérico dos ruminantes, inclusive o tipo de carboidrato fermentado, o sistema digestivo do animal, a quantidade e o tipo de alimentos consumidos. Diante do exposto, pesquisadores têm desenvolvido tecnologias para reduzir a emissão de metano, através da melhoria das práticas de manejo alimentar, manipulação ruminal, por meio de suplementação com monensina, lipídios, ácidos orgânicos e compostos de plantas. Outras estratégias de redução de metano que foram investigadas são: defaunação e vacinas, que buscam inibir micro-organismos metanogênicos e a metanogênese. Assim, a busca por sistemas de produção eficientes tem sido uma das perspectivas da pecuária mundial para reduzir a emissão de poluentes e intensificar a produção animal.

A área possui 375,04 ha de áreas de preservação permanente (APPs), e desta superfície verificou-se que apenas 72,17 ha (19,24%) encontram-se compostos por vegetação arbórea ou mata, e destas 302,87 ha precisam ser enriquecidos e reflorestados com vegetação nativa da região, de acordo com legislação vigente. Os dados de área possibilitam futuras propostas de modelos de adequação ambiental para a microbacia, de acordo com a legislação ambiental vigente.

Método monoscópico para a determinação automática da altura de edifícios em fotografias aéreas

This paper proposes a monoscopic method for automatic determination of building's heights in digital photographs areas, based on radial displacement of points in the plan image and geometry at the time the photo is obtained. Determination of the buildings' heights can be used to model the surface in urban areas, urban planning and management, among others. The proposed methodology employs a set of steps to detect arranged radially from the system of photogrammetric coordinates, which characterizes the lateral edges of buildings present in the photo. In a first stage is performed the reduction of the searching area through detection of shadows projected by buildings, generating sub-images of the areas around each of the detected shadow. Then, for each sub-image, the edges are automatically extracted, and tests of consistency are applied for it in order to be characterized as segments of straight arranged radially. Next, with the lateral edges selected and the knowledge of the flight height, the buildings' heights can be calculated. The experimental results obtained with real images showed that the proposed approach is suitable to perform the automatic identification of the buildings height in digital images.

Morphoquantitative aspects of nitrergic myoenteric neurons from the stomach of diabetic rats supplemented with acetyl-L-carnitine

The NADPH-diaphorase (NADPH-d) positive myoenteric neurons from the body of the stomach of rats with streptozotocin-induced diabetes with or without supplementation with acetyl-L-carnitine (ALC) were evaluated. At the age of 105 days the animals were divided into four groups: normoglycaemic (C), normoglycaemic supplemented with ALC (CC), diabetic (D) and diabetic supplemented with ALC (DC). The supplementation with ALC (200 mg/kg body weight/day) to groups CC and DC was made during 105 days. After this period the animals were killed and the stomach removed and subjected to the histochemical technique of NADPH-d for the staining of the neurons of the myoenteric plexus. The area of 500 neurons of each group was investigated, as well as the neuronal density in an area of 23.84 mm(2) in each stomach. ALC promoted reduction (P < 0.05) of fasting glycaemia, water ingestion and areas of the profiles of the cell bodies of the NADPH-d neurons in the diabetic animals. The density of these neurons was not statistically different in the groups studied. It is suggested, therefore, a moderate neuroprotective effect of ALC, because the diminishment of the areas of the neuronal profiles in the supplemented diabetic animals, although being statistically significant relative to the non-supplemented diabetics, was not sufficient to equal the values from the non-diabetic controls.

Study of the timber constructive systems that are more commercialized in Brazil

The Brazilian houses in wood are executed with several techniques and species, in function of the areas they are located, therefore, it is treated of regional traditional houses, built practically without modem technological resources. These houses are the ones of the tropical areas, where there is abundance of this material, or the ones of the south region, prevailing the European immigrant's constructive techniques. Nowadays, in the urbanized centers of the country it is observed that this type of house can be found sheltering the most lacking populations, in the slums; or in highly sophisticated residential units which are conceived and executed by specialist professionals for a social class of high purchasing power; or still, those that are marketed by companies of small load, that offer standardized residences, usually acquired by the middle class as second residence, in the field or in the coast. The work has for objective to study the houses of these companies that are consolidated at the market, identifying the constructive system, the product; as well as, its production process, trying to verify which technologies are incorporated to these processes. The analysis that was made allows a larger understanding of the product, wood house, that exists in the market and identification of the technological degree in the productive process of those constructive systems.

Remediação de solos contaminados com diesel por lavagem com solução de tensoativos

Combating pollution of soils is a challenge that has concerned researchers from different areas and motivated the search for technologies that aim the recovery of degraded soils. Literature shows numerous processes that have been proposed with the intent of remediating soils contaminated by oils and other by-products of the oil industry, considering that the processes available have, generally, high operating costs, this work proposes a costeffective alternative to the treatment of Diesel-contaminated soils. The washing solutions were prepared using water as aqueous phase, the saponified coconut oil (OCS) as surfactant and n-butanol as co-surfactant. In this study, the soil was characterized by physical and chemical analyses. The study of diesel desorption from the soil was held in bath, using hexane and washing solutions, which had 10 and 20 wt.% active matter (AM - co-surfactant/surfactants) respectively. The study of the influence of active matter concentration and temperature in bath agitated used an experimental planning. The experiment also developed a system of percolation in bed to wash the soil and studied the influence of the concentration of active substance and volume of washing solution using an experimental planning. The optimal times to achieve hexane extraction were 30 and 180 min, while the best results using a 10% AM was 60 min and using a 20% AM was 120 min. The results of the experimental planning on bath showed that the maximum diesel removal was obtained when at a 20 wt.% of AM and under 50 °C, removing 99.92% of the oil. As for experiments in the system of percolation soil bed, the maximum diesel removal was high when the volume of the washing solution was of 5 L and the concentration of 20% AM. This experiment concluded that the concentration of AM and the temperature were vital to bath experiments for diesel removal, while in the system of percolation soil bed only concentration of AM influenced the soil remediation
