We investigate the equilibrium morphology of a finite volume of liquid placed on two parallel rigid fibers of different radii. As observed for identical radii fibers, the liquid is either in a column morphology or adopts a drop shape depending on the inter-fiber distance. However the cross-sectional area and the critical inter-fiber distance at which the transition occurs are both modified by t...

introduction using agro-industrial by-products in ruminants feeding could help in semi arid climate condition throughout the year. raisin by-product is produced in huge magnitude in malayer city, hamedan province. local different raisin by-products which produced during machinery cleaning and sorting of sun dried treated grapevine cluster (vitisvinifera l. cv. sultana), are as:1) some outer lay...

Studies were conducted with four (50 to 70 kg) barrows to evaluate the mobile nylon bag technique (MNBT) for determining the apparent protein digestibility (AD) in a variety of feedstuffs. One-gram samples of each feedstuff, ground through a 1.0-mm mesh screen, were enclosed in nylon bags (25 X 40 mm; 48 microns mesh). Following predigestion (.01 N HCl; 4,000 Folin Intestinal Pepsin Units/liter...

The question of increasing the reliability and durability reinforced concrete structures is a priority. One ways to increase strength using dispersed reinforcement. interest fiber-reinforced in Russia, as well Europe, Asia USA has increased significantly recent ten years. improvement physical mechanical properties noted depend on reinforcement parameters, such volume content fiber, characterist...

In this work, ozone modification method and air-oxidation are used for the surface treatment of polyacrylonitrile(PAN)based carbon fiber. The surface characteristics of carbon fibers are characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites are investigated by means of the single fiber pull-out tests. As a ...

A hybrid composite consisting of rubber-toughened nylon-6,6, short glass fibers, and a thermotropic liquid-crystalline polymers (LCP) was investigated by the LCP content being varied. The thermal behavior, morphology, and crystallization behavior due to hybridization were studied by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), scanning electron microscopy (SEM), F...
