Mr. Don Walter should be commended for his technical paper dealing with the real-world problems of preparing anaerobic digester feeds from a difficult raw material, municipal solid waste (MSW). The information presented in the paper is not readily available in the published litera­ ture, and will be valuable to engineers interested in MSW processing and digestion. The author discusses some of t...

Maize and solvent extracted soybean meal (SBM) were ground through a 2 or 3 mm screen, resulting in “fine” and “coarse” material. The mean particle sizes of fine and coarse feed were 0.62 vs. 0.96 mm (maize) and 0.63 vs. 1.01 mm (SBM). Maize or SBM of either particle size was included in experimental diets at two different levels at the expense of maize starch. Three week old broilers had free ...

This article describes the effect of particle size distribution, pellet size and dehydration techniques on the improvement of physical properties of the pelleted feed products. It is shown that dehydration with vacuum has positive effect on durability when compared to air technique. Products volume and particle size distribution also had an effect on physical properties. INTRODUCTION In porous ...

the growing interest in using natural fibers as reinforcing agents of polymer-based composites is mainly due to their advantages such as lower cost, lower density, ease of preparation, lower energy requirements for processing, biodegradability, wide availability and relative non-abrasiveness over traditional reinforcing fibers such as glass and carbon. in this study, wood-plastic composite (wpc...

Nanocrystalline ZrO2 with particle size of about 38 nm was directly synthesized by sol-gel auto-combustion method. The overall process involved three steps: formation of homogeneous sol at 50-55°C; formation of dried gel at 110°C, and combustion of the dried gel at 400°C. Experiments revealed that ZrO2 dried gel derived from glycine (Fuel) and nitrate sol exhibited self pr...
