Two trials that utilized 356 yearling steers were conducted to evaluate the effects of fat sources (3.5% of diet dry matter) in steam-flaked milo finishing diets. Fats differed in fatty acid composition and level of free fatty acids. In Trial 1, soybean oil, tallow and yellow grease were compared to a nonfat control. Feeding fat increased (P less than .05) daily gain, feed efficiency, estimated...

The importance of providing adequate cleansing facilities for industrial workers, and in particular for those whose skin is constantly or frequently exposed to contamination with potentially harmful lubricating oils, is now well recognized. The removal of lubricating oils from the skin, although superficially an apparently simple matter, is, in fact, usually difficult to accomplish without usin...

In this work, a chemical modification method was used to prepare silicone grease with high thermal conductivity. We report two preparation methods for conductive fillers, which are hydroxylated boron nitride-grafted carboxylic oil (h-BN-OH@CS) and amino (h-BN-NH2@CS). When h-BN-OH@CS h-BN-NH2@CS were filled 30 wt% in the base grease, conductivity 1.324 W m−1 K−1 0.982 K−1, is 6.04 4.48 times th...

In this study, the influence of temperature on tribological properties unreinforced or glass-fiber reinforced PA66 in contact with carbon steel under boundary lubrication grease was studied when considering dependence mechanical sliding surface and tribochemical reaction to zinc carboxylate additives grease. XPS ToF-SIMS analyses revealed formation a tribofilm sulfide reactive film surface, whi...

The results of an experimental work carried out to evaluate the effect of palm oil methyl esters, also known as palm oil diesel (POD) and its emulsions as alternative fuel on unmodified indirect injection diesel engine's wear and lube oil performance are presented in this paper. Half throttle engine with constant 2500 rpm setting was maintained throughout the wear debris and lube oil analysis s...
