the influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. the incorporation of nanoclay into epoxy enhances the impact resistance of the composites. the impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...
Introduction: NEAR Shoemaker and HAYABUSA landed on asteroids and Philae of Roset-ta mission and HAYABUSA-2 are going to land on Churyumov-Gerasimenko comet and 1999 JU3 asteroid , respectively, as of writing this abstract. For such missions in the future, we suggest dust monitoring instrument on a CubeSat dispatched to the target body from the main spacecraft. CubeSat is a type of minia-turize...
We propose a simple continuum model to interpret the shearing motion of dense, dry and cohesion-less granular media. Compressibility, dilatancy and Coulomb-like friction are the three basic ingredients. The granular stress is split into a rate-dependent part representing the rebound-less impacts between grains and a rate-independent part associated with long-lived contacts. Because we consider ...
A descriptive predictive design was used to guide this study. The study conducted in Al-Qadisiyah University. included a convenience sample of 400 undergraduate students. instrument includes students’ sociodemographic sheet age, gender, marital status, and grade. It also Stages Change Scale for Grain Consumption, Decisional Balance Self-Efficacy Consumption. Data Collection: were collected usin...
The purpose of this note is to posit and discuss the concept of "competitive inhibition potential" (CIP), which is an in vivo index of the ability of a competitive inhibitor to elevate plasma concentrations of drug substrates, when the competitive inhibitor is administered at its usual and customary dose.
HST NICMOS PSF-subtracted coronagraphic observations of HD 181327 have revealed the presence of a ringlike disk of circumstellar debris seen in 1.1 m light scattered by the disk grains, surrounded by a diffuse outer region of lower surface brightness. The annular disk appears to be inclined by 31N7 1N6 from face-on, with the disk major-axis P.A. at 107 2 . The total 1.1 m flux density of the li...
