American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.519305
Abstract:

The aim of this study was to compare phenolic compounds contents between different positions within the crown and between collection periods, and to evaluate the tannin contents by the Folin-Ciocalteu method. The collections were performed in Lavras, in the southern region of the Brazilian state Minas Gerais. The experiment was conducted in a completely randomized design (factorial 3 × 4); the first factor being the position (base, middle, top); and the months, the second factor (February, May, September and December). We verified that the leaves of S. adstringens present higher total phenolic and tannin contents at the top (23.05% and 18.23%) and base (21.42% and 16.61%) of the crown, in May (25.79% and 20.85%) and September (25.57% and 20.50%), respectively. There was no difference in the residual phenol and flavonoid contents between the positions within the crown or in the months of collection. These facts suggest that within the crown and climatic changes may be one of the factors affecting phenol levels in Stryphnodendron adstringens.

Revista Brasileira de Ciências do Envelhecimento Humano , 2007,
Abstract: No processo de envelhecimento, as rela es de gênero determinam uma grande fragiliza o das mulheres, levando-as à necessidade de buscar uma identidade dentro de contextos de relacionamento criados no interior do seu grupo de referência. Visando à identifica o de elementos subsidiários à concep o de programas de apoio psicossocial voltados para este segmento social, foram identificadas algumas categorias de análise, relacionadas à prática de atividades físicas. Uma análise de conteúdos com base na inclus o em categorias temáticas ex post facto, realizada sobre entrevistas semi-estruturadas com dez mulheres com idades acima de sessenta anos, permitiu identificar três grandes blocos de itens: a) alternativas à inércia/isolamento, relacionadas à socializa o; b) saúde mental, com base em realiza o e experiência; c) condicionamento físico, compreendendo desdobramentos como a vivência dos limites, o caráter de preven o a doen as e de facilita o nas tarefas diárias. Tais resultados identificam, no caráter receptivo e de continência dos grupos para a realiza o de atividades físicas, alguns elementos de ativa o e de saída da inércia e suas decorrências para o equilíbrio emocional e auto-estima, ligados a conteúdos presentes nos processos de forma o de identidade, na mulher idosa, com a retomada da auto- realiza o e reconstitui o de danos causados por limites determinados por papéis de gênero e estigmas do envelhecimento.

Abstract: the superior mesenteric syndrome is a rare and controversial disease. the compression of the duodenum by the mesenteric artery and aorta causes an intermitent obstruction. preoperative diagnosis is very difficult.we present one case of this syndrome in a pacient with severe weight loss and signs of high intestinal obstruction. the diagnosis was based on clinical and radiologic findings. a duodenojejunostomy was performed after medical treatment failure.this patient died on the 20th posoperative day due to cardiac complications. this syndrome must be remembered in cases of high obstruction in chronic ill patients.
FORECASTING RESIDENTIAL ELECTRICITY CONSUMPTION IN BRAZIL: APPLICATION OF THE ARX MODEL PREVIS O DO CONSUMO RESIDENCIAL DE ENERGIA ELéTRICA NO BRASIL: APLICA O DO MODELO ARX
Joao Bosco de Castro,Alessandra de ávila Montini
Future Studies Research Journal : Trends and Strategies , 2011, DOI: 10.7444/future.v2i2.50
Abstract: This work aims to propose the application of the ARX model to forecast residential electricity consumption in Brazil. Such estimates are critical for decision making in the energy sector, from a technical, economic and environmentally sustainable standpoint. The demand for electricity follows a multiplicative model based on economic theory and involves four explanatory variables: the cost of residential electricity, the actual average income, the inflation of domestic utilities and the electricity consumption. The coefficients of the electricity consumption equation were determined using the ARX model, which considers the influence of exogenous variables to estimate the dependent variable and employs an autoregression process for residual modeling to improve the explanatory power. The resulting model has a determination coefficient of 95.4 percent and all estimated coefficients were significant at the 0.10 descriptive level. Residential electricity consumption estimates were also determined for January and February 2010 within the 95 percent confidence interval, which included the actual consumption figures observed. The proposed model has been shown to be useful for estimating residential electricity consumption in Brazil. Key-words: Time series. Electricity consumption. ARX modeling. O objetivo deste trabalho é propor a aplica o do modelo ARX para fazer previs es do consumo residencial de energia elétrica no Brasil, fundamentais para suportar decis es do setor de energia em bases técnica, econ mica e ambientalmente sustentáveis. A fun o da demanda de energia elétrica foi modelada segundo um modelo multiplicativo com base na teoria econ mica e incluiu quatro variáveis explicativas: tarifa residencial de energia elétrica, rendimento médio real das pessoas ocupadas, índice de infla o de utilidades domésticas e consumo de energia. Para estimar os coeficientes da equa o do consumo de energia elétrica, foi utilizado o modelo ARX, o qual considera na proje o da variável dependente a influência de variáveis exógenas e modela os resíduos por meio de um processo auto-regressivo a fim de aumentar seu poder explicativo. Resultados indicaram um coeficiente de determina o de 95,4% e todos os coeficientes estimados foram estatisticamente significantes a um nível descritivo de 0,10. Foram realizadas proje es do consumo residencial de energia elétrica para os meses de janeiro e fevereiro de 2010 no intervalo de c

Revista Sociedade, Contabilidade e Gest?o , 2012,
Abstract: The objective of this paper is to propose the application of the SARX model to arrive at industrial power consumption forecasts in Brazil, which are critical to support decision-making in the energy sector, based on technical, economic and environmentally sustainable grounds. The proposed model has a seasonal component and considers the influence of exogenous variables on the projection of the dependent variable and utilizes an autoregressive process for residual modeling so as to improve its explanatory power. Five exogenous variables were included: industrial capacity utilization, industrial electricity tariff, industrial real revenues, exchange rate, and machinery and equipment inflation. In addition, the model assumed that power forecast was dependent on its own time lags and also on a dummy variable to reflect 2009 economic crisis. The study used 84 monthly observations, from January 2003 to December 2009. The backward method was used to select exogenous variables, assuming a 0.10 descriptive value. The results showed an adjusted coefficient of determination of 93.9% and all the estimated coefficients were statistically significant at a 0.10 descriptive level. Forecasts were also made from January to May 2010 at a 95% confidence interval, which included actual consumption values for this period. The SARX model has demonstrated an excellent performance for industrial power consumption forecasting in Brazil.
