Innovations in beef carcass fabrication to improve subprimal yield, retail cut yield, and overall carcass value were evaluated. Alternating sides from 30 beef carcasses were assigned to either an innovative or conventional style of fabrication. The innovative method resulted in greater (P<0.001) total subprimal yield and less (P<0.001) lean trimmings from the forequarter; however, hindquarter t...

Catalytic naphtha reforming is one of the most important processes in which, low quality naphtha is converted into high octane motor gasoline. In this study, a mathematical model was developed and was used for investigation the effect of temperature, pressure, hydrogen to hydrocarbon ratio on the octane number, the yield of product and the undesirable phenomena of coke deposition in a semiregen...

This paper describes experimental research to directly quantify the ordinary heterotrophic organism (OHO) cell yield coefficient under anoxic and aerobic conditions with real wastewater as substrate. Until recently these two values were assumed equal in activated sludge models, despite theoretical predictions that the anoxic yield should be reduced relative to its aerobic value. In this study, ...

Herd differences in value of milk for fluid use, nonfat dry milk, and Cheddar, Swiss, Mozzarella, and cottage cheeses were determined. Data were 1988 herd average fecords from the National Cooperative Dairy Herd Improvement Program that included milk, fat, and protein yields from 50,608 herds (3.8 million cows) that produced 28.8 billion kg of milk Values of annual yield were calculated both on...

objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...
