A polymerase chain reaction (PCR) assay has been developed for genotyping beta-lactoglobulin A and B variants in dairy cattle. Either blood or semen samples can be used as a source of DNA. The method is accurate, faster than Southern blot analyses an

Saliva influences rumen function in cattle, yet the biochemical role for most of the bovine salivary proteins (BSPs) has yet to be established. Two cDNAs (BSP30a and BSP30b) from bovine parotid salivary gland were cloned and sequenced, each coding fo

A model is derived for waterjet cutting of soft materials. These are low shear strength materials such as leather, soft woods, rubber, and some plastics. The model is based on the deflection of the jet within the material and an assumed erosion proce
