nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. in this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of prangos ferulaceae leaves. the synthesized silver nanoparticles were characterized by uv-vis spectroscopy, scanning el...

in order to examine the effect of the quantity of nitrogen fertilizer and bush density on vegetative and productive function of henna medicinal plant (lawsonia inermis)  factorial experimentation in the form of block plan was carried in three stages in agriculture research center in south of kerman  province in corp of 2012. the first factor containing nitrogen fertilizer in 4 levels including ...

This paper analyzes the e¤ect of federal and state maternity leave policies on female employment. We analyze if the enactment of the federal Family Medical Leave Act (FMLA) di¤erentially a¤ected states that previously implemented maternity leave laws at the state level than those states which did not. Additionally, we study whether FMLA caused an increase in the female employment and labor forc...

Model selection measures such as hold-out set error, cross-validation error, leave-one-out error etc. are used to evaluate the performance of a classification algorithm on a given data set. To get an accurate estimate of the performance it is important that we choose the appropriate model selection measure or evaluation measure for the setting of interest. In this paper, we describe in brief a ...

Mounting evidence across different disciplines suggests that early-life conditions can have consequences on individual outcomes throughout the life cycle. Relative to other developed countries, the United States fares poorly on standard indicators of early-life health, and this disadvantage may have profound consequences not only for population well-being, but also for economic growth and compe...

OBJECTIVE To report the number of participants needed to recruit per baby born to trial staff during AVERT, a large international trial on acute stroke, and to describe trial management consequences. DESIGN Retrospective observational analysis. SETTING 56 acute stroke hospitals in eight countries. PARTICIPANTS 1074 trial physiotherapists, nurses, and other clinicians. OUTCOME MEASURES N...

today, the work-family conflict is a challenge to nurses and nursing. in this regard, the ghaem hospital's 448 nurses making random sample of 100 individuals were studied. to analysis collected data, partial least squares (pls) and haland procedures were employed.the results were significant and positive relationship between the variables of a conflict between people intention to leave, and wor...

OBJECTIVES To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF) among working women. METHODS This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalenc...

Projection pursuit index measuring quality of projected clusters (QPC) introduced recently optimizes projection directions by minimizing leave-one-out error searching for pure localized clusters. QPC index has been used in constructive neural networks to discover non-local clusters in high-dimensional multiclass data, reduce dimensionality, aggregate features, visualize and classify data. Howev...

A bound on the leave-one-out error for -support vector (SV) machine binary classifiers is presented. This bound is based on the geometrical concept of the span, which was introduced in the context of bounding the leave-one-out error for C-SV machine binary classifiers. It is shown that the bound presented herein requires less restrictive assumptions than the C-SV bound, and that the prediction ...
