Componentes de rendimento da mamoneira irrigada com diferentes lâminas de irrigação.
O trabalho foi conduzido na Fazenda Experimental Rafael Fernandes, município de Mossoró, RN, com o objetivo verificar o efeito de lâminas de irrigação sobre os componentes de rendimento da mamoneira, cultivar ?BRS ENERGIA?, irrigada por gotejamento. Para tanto, utilizou-se o delineamento experimental em blocos ao acaso, em esquema de parcelas subdivididas 5 x 2, com quatro repetições. Os tratamentos foram constituídos das lâminas de irrigação (0,6; 0,8; 1,0; 1,2; e 1,4 da ETc) nas parcelas principais e os espaçamentos nas sub-parcelas (1,5m x 0,30m x 0,30m e 1,5m x 0,30m x 0,40m). Foram tomados dados referentes ao número médio de bagas dos racemos principal e secundário, peso médio da baga (g) dos racemos principal e secundário e número de racemos secundários por planta. Número de bagas do racemo secundário e peso médio da baga do racemo principal apresentaram comportamento quadrático com as lâminas de irrigação aplicadas. O incremento na lâmina favoreceu o aumento do número de racemos secundários por planta

Antioxidant intake among Brazilian adults - The Brazilian Osteoporosis Study (BRAZOS): a cross-sectional study
<p>Abstract</p> <p>Background</p> <p>Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health.</p> <p>Methods</p> <p>The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant.</p> <p>Results</p> <p>Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits.</p> <p>Conclusion</p> <p>These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.</p
Measurement of flavor asymmetry of light-quark sea in the proton with Drell-Yan dimuon production in and collisions at 120 GeV
Evidence for a flavor asymmetry between the and quark
distributions in the proton has been found in deep-inelastic scattering and
Drell-Yan experiments. The pronounced dependence of this flavor asymmetry on
(fraction of nucleon momentum carried by partons) observed in the Fermilab
E866 Drell-Yan experiment suggested a drop of the ratio in the region. We report results from the
SeaQuest Fermilab E906 experiment with improved statistical precision for in the large region up to
using the 120 GeV proton beam. Two different methods for extracting the
Drell-Yan cross section ratios, , from the SeaQuest
data give consistent results. The ratios and the differences are deduced from these cross section ratios for
. The SeaQuest and E866/NuSea ratios are in good agreement for the
region. The new SeaQuest data, however, show that
continues to be greater than up to the highest value
(). The new results on and are
compared with various parton distribution functions and theoretical
calculations
