In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....

Assembly of carbon nanotubes (CNTs) in effective and productive ways is of vital importance to their application. Recent progress in synthesis of CNTs has inspired new strategies for utilizing the unique physiochemical properties of CNTs in macroscale materials and devices. Assembling CNTs by dry processes (e.g., directly collecting CNTs in the form of freestanding films followed by pressing, s...

se of freeze granulated powders is successfully used as an industrially viable alternative to loose powder sintering for transparent polycrystalline lumina (PCA). Freeze granulation with narrow granule size distribution was realized after suspension condition optimization, with very good owability and regular spherical shapes. The key factors are low viscosity slurries linked to the complex int...

nitrate toxicosis associated with consumption of pigweed red-root (amaranthus retroflexus) wasdiagnosed in a small herd of cattle in the suburb of mashhad, northeastern iran. the clinical signs wereruminal tympany, incoordination, tachycardia, dyspnea, head pressing, aggressive movements and jugulardistension. seven animals including 3 young calves and 4 cows died of intoxication; other affecte...

Tiger nut (Cyperus esculentus) tuber contains oil that is high in monounsaturated fatty acids, and this oil makes up about 23% of the tuber. The study aimed at evaluating the impact of several factors and enzymatic pre-treatment on the recovery of pressed tiger nut oil. Smaller particles were more favourable for pressing. High pressure pre-treatment did not increase oil recovery but enzymatic t...

In porous ceramics processing, the green body shaping technique largely determines control of final structure and material properties. The study is aimed at finding affordable approaches for two different narrow-fraction fillers: F240 electro-corundum hollow alumina microspheres. results revealed influence accessible techniques (semi-dry pressing, direct casting, slip casting) on structural mec...
