Abstract: Hipertens o Arterial e Diabetes Mellitus constituem os principais fatores de risco para doen as cardiovasculares. Neste contexto, o acompanhamento farmacoterapêutico demonstra ser uma importante estratégia de controle destas condi es de saúde. Como objetivo, avaliou-se as características dos usuários do Programa Nacional de Hipertens o e Diabetes (Hiperdia) em uma Unidade de Saúde Pública, para averiguar a necessidade de implantar um servi o de Aten o Farmacêutica. Utilizaram-se questionários para verificar a compreens o do usuário sobre: doen a, terapia medicamentosa e ades o ao tratamento. Observou-se que dos 50 usuários entrevistados, a média de idade foi 56,68 ±10,1 anos, sendo 82% gênero feminino. 62% apresentaram ensino fundamental, 12% eram analfabetos e 32% tinham algum conhecimento sobre sua doen a. Em rela o aos medicamentos prescritos, 10% compreendiam o intervalo de uso, 14% relataram dificuldades em tomar e 50% esqueciam de tomá-los. Verificou-se, um gasto de R$785,00/mês com medicamentos, cuja média de atendimento foi para 980 usuários. O que demonstra baixo custo no tratamento, n o justificando os altos índices de interna es hospitalares e morbimortalidade presentes no país. Portanto, acompanhamento farmacoterapêutico poderia contribuir para otimizar os resultados clínicos e reduzir gastos em saúde. Palavras-chave: Hipertens o, Diabetes, Aten o Farmacêutica.

Abstract: The foliar application and seed Ca + B, Mo + P and Stimulate? in peanut, despite being a practice used long ago, few studies have conclusive results, and then this research was to evaluate the physical and physiological quality peanut seeds from the process of application of fertilizers and bio-stimulant. The design was completely randomized, with seed from peanut plants subjected to the use of three products (Ca + B; Mo + P and Stimulate?), two types of applications (via leaf and seeds), growing with PK and absolute control, following a factorial arrangement of [(3 × 2) + 2]. For the dimensions (length and width) of seeds, as well as the thousand seed weight and number of seeds per pod, data were submitted to descriptive statistics, calculating the mean, standard deviation, variance and coefficient of variation of the data obtained. The application of fertilizers, bio-stimulants and groundnut seeds increases germination of seeds produced, causes more seedlings that are vigorous and reduces the percentage of abnormal seedlings.
Real Estate Evaluation engineering suported by multicriteria analysis and artificial neural network
Salesian Journal on Information Systems , 2010,
Abstract: To evaluate real estates means estimate its market value, taking into account several factors, such as: the particular characteristics of the property, market conditions and the balance between stakeholders in the negotiation. All these features make the evaluation a complex task, mainly because the real estate market represents an important segment of the national economy requiring more precise results. In this context, we conducted a survey on evaluation methodologies of properties that are used and identified that the main technique, regression analysis, has limitations that may compromise the outcome of the evaluation. This paper presents the research methodology developed using Multicriteria Analysis and Artificial Neural Network to evaluate residential apartments. The results were considered very satisfactory, indicating that the combination of multicriteria analysis and artificial neural network is efficient and promising.

Journal of the Brazilian Chemical Society , 1999,
Abstract: Presented here is a new process in two stages for bleaching peroxyformic sugar cane bagasse pulp combining photosensitization and photocatalysis. The first stage consists of an irradiation (1h), with tungsten or mercury lamps, of the pulp under alkaline pH in aqueous suspension at a consistency of 5% with TiO2 and methylene blue (MB) or 3,4,9,10-perylenetetracarboxylic acid (PTCA) or Fe (II) 4,4?,4??,4???-tetrasulfophthalocyanine (TSPC) (concentration " 10-5 mol L-1) in the presence of bubbling oxygen and hydrogen peroxide (2% pulp basis). The second photobleaching stage performed with hydrogen peroxide (3%) efficiently completed the delignification and the brightness gain, removing completely the sensitizer from the pulp. Under those conditions, efficient bleaching of the pulp was obtained, using uv/vis light and PTCA or MB (unbleached pulp: kappa number: 13, brightness: 44, viscosity: 900 dm3 kg-1; bleached pulp: kappa number: 1.2-1.3, brightness: 86, viscosity: 510-550 dm3 kg-1) or visible light with MB (kappa number: 1.7, brightness: 80, viscosity: 625 dm3 kg-1). The mechanisms of photobleaching to increase the selectivity and the efficiency of the process remain to be established.
Modelación de episodios críticos de contaminación por material particulado (PM10) en Santiago de Chile: comparación de la eficiencia predictiva de los modelos paramétricos y no paramétricos
Alvarado,Sergio A.; Silva,Claudio S.; Cáceres,Dante D.;
Gaceta Sanitaria , 2010, DOI: 10.1590/S0213-91112010000600006
Abstract: objective: to evaluate the predictive efficiency of two statistical models (one parametric and the other non-parametric) to predict critical episodes of air pollution exceeding daily air quality standards in santiago, chile by using the next day pm10 maximum 24h value. accurate prediction of such episodes would allow restrictive measures to be applied by health authorities to reduce their seriousness and protect the community's health. methods: we used the pm10 concentrations registered by a station of the air quality monitoring network (152 daily observations of 14 variables) and meteorological information gathered from 2001 to 2004. to construct predictive models, we fitted a parametric gamma model using stata v11 software and a non-parametric mars model by using a demo version of salford-systems. results: both models showed a high correlation between observed and predicted values. however, the gamma model predicted pm10 values below 240μg/m3 more accurately than did mars. the latter was more efficient in predicting pm10 values above 240μg/m3 throughout the study period. conclusion: mars models are more efficient in predicting extreme pm10 values and allow health authorities to adopt preventive methods to reduce the effects of these levels on the population's health. the reason for this greater accuracy may be that mars models correct variations in the series over time, thus better fitting the curve associated with pm10 concentrations.

Nonextensive Quantum H-Theorem
R. Silva,D. H. A. L. Anselmo,J. S. Alcaniz
Physics , 2009, DOI: 10.1209/0295-5075/89/10004
Abstract: A proof of the quantum $H$-theorem taking into account nonextensive effects on the quantum entropy $S^Q_q$ is shown. The positiveness of the time variation of $S^Q_q$ combined with a duality transformation implies that the nonextensive parameter $q$ lies in the interval [0,2]. It is also shown that the equilibrium states are described by quantum $q$-power law extensions of the Fermi-Dirac and Bose-Einstein distributions. Such results reduce to the standard ones in the extensive limit, thereby showing that the nonextensive entropic framework can be harmonized with the quantum distributions contained in the quantum statistics theory.

Abstract: a mixture of bovine dna from a male and a female jersey (bos taurus taurus) bred in different proportions was used to determine the sensitivity of pcr to amplify and discriminate the bovine dna samples. samples were obtained from the peripheral blood of a bull and a heifer and dna was isolated using a commercial kit for extraction and purification of nucleic acids. two primers sets were designed to flank genomic regions: one autosomal and one y-specific. dna samples were diluted in water to a final concentration of 4x10-14 ng. the results showed positive amplification of the samples diluted to a concentration of 4x10-10ng and 4x10-4ng for the autosomal and y-specific regions, respectively. pcr was able to discriminate the male dna in a mixture of 99:1 (dna ♀: dna ♂) heifer to bull ratio. therefore, the pcr was successful in amplifying the bovine genome in samples containing low concentrations of dna. thus, pcr can be used as a sensitive and efficient tool to determine the sex of the fetus in pregnant cows, helping to promote correct and efficient animal management, sex selection, and breeding in commercial herds.
