Steady glide trajectory optimization for high lift-to-drag ratio reentry vehicle is a challenge because of weakly damped trajectory oscillation.This paper aims at providing a steady glide trajectory using numerical optimal method.A new steady glide dynamic modeling is formulated via extending a trajectory-oscillation suppressing scheme into the thr
Purpose: The purpose of the present study was to analyze the effects of green tea infusion on the toxicity of ovaries of female rats treated with the contraceptive depot-medroxyprogesterone acetate (DMPA).Material and Methods: A total of twenty-four female rats were randomly divided into four groups, incuding the control group (no treatment), the D
Wastewater contains a large range of biological and chemical markers of human activity and exposures.Through systematic collection and analysis of these markers within wastewater samples it is possible to measure the public health of whole populations.The analysis of effluent and biosolids can also be used to understand the release of chemicals fro
Abstract The presence of many pathogens varies in a predictable manner with latitude, with infections decreasing from the equator towards the poles.We investigated the geographic trends of pathogens infecting a widely distributed carnivore: the gray wolf (Canis lupus).Specifically, we investigated which variables best explain and predict geographic
