The purpose of this note is to analyze male excess mortality in relation to general mortality trends in a country with low levels of mortality, using Italian data for the period 1951-1981, and to examine the effect of this excess male mortality on the sex distribution of the population. Consideration is given to the apparent paradox whereby "at least(More)
The main limitation for determining feed efficiency of freely grazing ruminants is measurement of daily individual feed intake. This paper describes an investigation that assessed a method for estimating intake of forage based on changes in BW of ewes. A total of 24 dry and non-pregnant Romane ewes (12 hoggets, HOG; mean±SD 51.8±2.8 kg BW; body condition(More)
Conversion of cephalosporin C into glutaryl 7-aminocephalosporanic acid was catalysed by D-aminoacid oxidase from Trigonopsis variabilis, covalently immobilized on the polystyrenic resin Duolite A365. Spontaneous degradation of substrates was limited without depressing enzymatic activity at the optimum reaction pH 8.0. The highest product yield was 1.77(More)
Four different hysrolytic enzymes were isolated and partially purified from Brevibacterium imperiale B222 cells. The stereoselectivity of each enzyme was assayed by using the nitrile, amide and esters derivatives of 2-aryloxypropionic acid. Within the cellular pool of hydrolytic enzymes, a non-stereoselective nitrile hydratase, a stereoselective amidase and(More)
