Estimates of hourly diffuse radiation on tilted surfaces in southeast of brazil

Abstract: The global radiation incident on a tilted surfaces consists of components direct, diffuse and reflected from the ground. On a hourly database, the direct radiation can be calculated by geometric projections (ratio of the incidence angle to the solar zenith angle). The reflected radiation has a small effect on calculations and may be calculated with an isotropic model. Both components presents dependence of measures in incidence or horizontal surface. The great difficulty is to evaluate the diffuse radiation by variations of circumsolar, brightness horizontal, isotropic and anisotropic subcomponents. This study evaluated twenty models to estimate hourly diffuse radiation incident on tilted surfaces at 12.85° (latitude - 10°), 22.85° (latitude) and 32.85° (latitude + 10°) facing to North, under different cloudiness sky conditions, in Botucatu, Sao Paulo State, Brazil (22°53′ S, 48°26′ W and 786 m above the mean sea level). In contrast, models for estimating the diffuse component show major differences, which justify the validation for local calibrations. There is a decrease of the maximum total radiation scattered with increasing atmospheric transmissivity and inclination angle. The best results are obtained by anisotropic models: Ma and Iqbal, Hay, Reindl et al. and Willmott; isotropic: Badescu and Koronakis, and the Circumsolar model. The increase of the inclination angle allows for a reduction in the performance of statistical parametric models for estimating the hourly diffuse radiation.

Resting energy expenditure measured vs. estimated and this relationship with body composition in women

Abstract: OBJECTIVES: To compare the resting energy expenditure (REE, kcal/d) measured to the disposable equation of literature and to associate this to body composition. METHODS: Twenty-eight sedentary women were volunteers [weight: 79 ± 12 kg; stature: 164 ± 5 cm; age: 36 ± 11 years; body mass index (BMI, kg/m2): 29 ± 4]. The body composition was estimated with anthropometry methods; REE was measured by indirect calorimetry and was estimated by the main equations of the literature. Equations were developed to estimate REE and the best of them was REE-Our. RESULTS: The different time of harvest produced a similar result to REE measured. The Harris & Benedict, FAO/WHO/UNO only weight, and weight plus height, Schofield and REE-Our equations results were statistically similar to REE measured. The Siervo & Falconi, Schofield and Henry & Rees equations did not have correlation with the measured calorimetry. The best-isolated predictor of the REE was the body mass and the best association when adjusted to unit (kg) was lean body mass. The equation developed in the present work was: REE(kcal/d)= 21837 - 14,448 * Weight(kg) + 54,963 * Lean Mass(kg) - 9,341 * Stature(cm) - 4,349 * Age(years) - 19753 * Body Density(g/ml). CONCLUSION: The REE prediction equations can prompt to errors and seem to be population specific. The best prediction result was with the equation developed with anthropometrics variables of the volunteers (measured= 1617 ± 237 kcal/d; REE-Our= 1616 ± 167 kcal/d).

Percepções de enfermeiros sobre seu trabalho na Estratégia Saúde da Família

Abstract: This study aimed to analyze the perceptions of nurses regarding their work in the Family Health Strategy. It consists of a qualitative descriptive study based on the socio-historical foundations and intersubjective aspects of the nursing work. Data were collected in 11 Family Health Units in Cuiaba, Mato Grosso, Brazil, by means of semi-structured interviews with 11 nurses, and submitted to thematic analysis. The nursing work is perceived as based on strategic and preventive actions, on the participation in the delivery of care, in contrast to the administrative participation, and on embracing interactions with patients. The nurses demonstrated compliance with the axes proposed for the work in the Family Health Strategy and a certain lack of knowledge and unchallenged acceptance of these, especially with respect to the promotion of health and the renewal of the local administrative practice. This study reveals the importance of reflecting regarding the nursing work and the perceptions of nursing professionals as for the construction of the Family Health Strategy model. DESCRIPTORS: Family Health Program. Nursing. Work. Social values.

Anti-inflammatory, antinociceptive, and antipyretic effects of methanol extract of Cariniana rubra stem bark in animal models

Abstract: Cariniana rubra Miers (Lecythidaceae), popularly known as “jequitiba-vermelho”, is a large Brazilian tree whose bark is used in infusion and decoction for the treatment of inflammatory conditions. This study aims to assess the anti-inflammatory, antinociceptive, and antipyretic effects of Cariniana rubra methanolic stem bark extract (EMCr) using experimental animals. Anti-inflammatory activity of EM Cr was tested on carrageenan and dextran-induced rat paw edema, carrageenan-induced pleurisy in rats and acetic acid-increase vascular permeability in mice. Antinociceptive and antipyretic activities were evaluated using acetic acid-induced writhing, formalin and hot-plate tests in mice, as well as brewer’s yeast-induced pyrexia in rats. The extract inhibitied carrageenan and dextran-induced edema, reduced exudate volume and leukocyte migration on the carrageenan-induced pleurisy and on the vascular permeability increase induced by acetic acid. The EMCr inhibited nociception on the acetic acid-induced writhing and in the second phase of formalin test, and decreased rectal temperature. It was, however, inactive against thermal nociception. Phytochemical analysis with EMCr showed the occurrence of saponins, triterpenes, sterols and phenolic compounds. Phytosterols ( β -sitosterol, stigmasterol), pentacyclic triterpenes ( α - and β -amyrin as a mixture), arjunolic acid, a phytosterol glycoside (sitosterol 3-O- β -D-glucopyranoside), and triterpenoid saponins (28- β -glucopyranosyl-23-O-acetyl arjunolic acid; 3-O- β -glucopyranosyl arjunolic acid and 28-O-[ α -L-Rhamnopyranosyl-(1 → 2)- β -glucopyranosyl]-23O-acetyl arjunolic acid) were the main identified compounds. It can be presumed that EM Cr caused their effects by inhibiting the liberation and/or action of different inflammatory mediators. These findings support the traditional use of Cariniana rubra preparations to treat inflammation.
