BACKGROUND Poor fetal growth has been associated with impaired airway function in adult life, but evidence linking birth weight and airway function in early childhood is sparse. We examined the hypothesis that low birth weight for gestation is associated with impaired airway function shortly after birth and that this is independent of impaired postnatal somatic growth. METHODS Airway function...

I. The effects of varying levels of physical activity were tested in rats, starting at ages of 21, 32 and 55 days and continuing until go, 100, 125 and 205 days. 2. Weight changes did not differ significantly between the exercise groups, except in the groups tested up to zog days, when both the exercised group and the group with limited activity were significantly lighter than the control group...

We report on recent progress in the search for dark matter particles with masses from 1 Mev c ^{-2} −2 to Gev . Several candidates this mass range are expected generate measurable electronic-recoil signals direct-detection exp...

The effects of dam previous reproductive status (PRS) on the pre-adjustment of weaning weight for genetic evaluation (WWT) was examined for Santa Gertrudis (SANTA), Brahman (BRAH) and Tropical Composite (TCOMP) breeds of beef cattle. Weaning weight records were classified into 3 groups according to the dam’s PRS: whether in the last year, she had reared a bull calf (PBC), a heifer calf (PHC) or...

A three-member team designed to leverage the unique capabilities of the US Army, industry, and MIT, the ISN mission is to provide a dramatic increase in survivability to the individual Soldier through nanoengineered materials and devices incorporated within a lighter-weight uniform. This mission includes not only decreasing the weight that Soldiers carry, but also improving blast and ballistic ...

INTRODUCTION Hearing protection devices are one of the primary noise reduction tools in developing countries. This study is intended to produce and apply acrylonitrile butadiene styrene (ABS)/clay nanocomposites to fabricate a laboratory single cup earmuffs and then compare it with double cup and single cup pure ABS earmuffs in terms of noise attenuation performance and comfort. In addition, th...

Lighter and lighter products are required by aerospace automotive sectors in order to reduce fuel cost carbon dioxide emissions and, allow using green energy propulsion, such as the electric one. In lighten parts aluminium alloys, which have a high strength weight ratio, most commonly used metal materials. They manufactured through plastic deformation processes often tailored blanks. This work ...
