The present study was aimed to evaluate the anti-ferlility activity of Caesalpinia pulcherrima Linn in rats. plant is a shrub or small tree. normally considered be an ornamental which planted gardens and parks for its beautiful red yellow flowers. phytochemical screening has shown presence various chemical constituents like alkaloids, flavonoids, steroids triterpenes. bark extracts have exhibit...

Contrary to claims about the irrelevance of philosophy for science, I argue that has had, and still has, far more influence on physics than is commonly assumed. maintain current anti-philosophical ideology had damaging effects fertility science. also suggest recent important empirical results, such as detection Higgs particle gravitational waves, failure detect supersymmetry where many expected...

seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. despite the diversity in quality and quantity of the mediterranean tunisian coast flora, with its large contains of marine organisms and seaweeds, most of them have not yet been ...

This study aims to understand trends in global fertility from 1950-2010 though the analysis of age-specific fertility rates. This approach incorporates both the overall level, as when the total fertility rate is modeled, and different patterns of age-specific fertility to examine the relationship between changes in age-specific fertility and fertility decline. Singular value decomposition is us...

Fertility has declined very markedly in the majority of developing countries over the past thirty to forty years, and it continues to decline almost everywhere. As a result, fertility has reached very low levels in many countries. In addition, currently more than 40 per cent of the world’s population lives in countries with total fertility levels lower than 2.1 children per woman, the level tha...

Soil fertility and nutrient-related plant functional traits are in general only moderately related, hindering the progress in trait-based prediction models of vegetation patterns. Although the relationships may have been obscured by suboptimal choices in how soil fertility is expressed, there has never been a systematic investigation into the suitability of fertility measures. This study, there...
