Road traffic injuries as a man-made calamity impose great burden on poor people and needs to be addressed through social justice and end of poverty. Pointing out that around 186,300 children under the age of 18 are killed every year, and much more are injured, urgent need to work on road safety measures will be revealed. Although preventing road traffic crashes from occurring should be the main...

O binômio tempo temperatura possui relação intrínseca com a qualidade dos alimentos expostos e tem como propósito o controle da inocuidade através do monitoramento alimentos. Os encarcerados têm direito à alimentação adequada saudável independente sua condição, neste caso liberdade privativa de direito. Este trabalho objetivo analisar refeições na etapa distribuição em Unidade Prisional Feminin...

Let 77l5..., 77w,... be a sequence of Independent integer-valued random variables. Let SnT]l + -~ + 7jn,Ari = ESn, B* = varS„,P„(m) = P(Sn = m), and f(t,rfj) denote the characteristic function of the random variable 77 •. The local limit theorem (LLT) is formulated as Pn(m) = (27rBy -exp{-(m^f /2B} + o(B~) when n-^00 uniformly for m. The first results on the normal approximation of binomial dis...

Thoroughly tested simulation models are needed to help quantify the long-term effects of agriculture. We evaluated the Root Zone Water Quality Model (RZWQM) response to different N management strategies and then used the tested model with observed weather data from 1961– 2003 to quantify long-term effects on corn (Zea mays L.) yield and flow weighted nitrate-N concentration in subsurface “tile”...

Relative contributions of diverse, managed ecosystems to greenhouse gases are not completely documented. This study was conducted to estimate soil surface fluxes of carbon dioxide (CO(2)), methane (CH(4)), and nitrous oxide (N(2)O) as affected by management practices and weather. Gas fluxes were measured by vented, static chambers in Drummer and Raub soil series during two growing seasons. Trea...

The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers region (FP), and an ecologically intensified (EI) over two consecutive maize growing seasons (2011–12 2012–13), ii) relate factors. Gas measured using vented static chambers, from October through April each season. Fluxes ranged 3 88 ?g N2O-N m?2 h?1 2011–12, between 97 2012–13....

SIRT1 takes down tumors Y uan et al. have identifi ed another anti-cancer effect of the “longevity” protein SIRT1. By speeding the destruction of the tumor promoter c-Myc, SIRT1 curbs cell division. The yeast and nematode equivalents of SIRT1 are fountains of youth that stretch lifespan. Whether SIRT1 slows aging in mammals isn’t certain, but it’s benefi cial in other ways. The protein tunes up...

We investigate a model of gate failure for Boolean circuits in which a faulty gate is restricted to output one of its input values. For some types of gates, the model (which we call the short-circuit model of gate failure) is weaker than the traditional von Neumann model where faulty gates always output precisely the wrong value. Our model has the advantage that it allows us to design Boolean c...
