Influence of the Digestive Tract on Enzyme Activity
Autor: D. A. Ksenofontov, A. A. Ksenofontova
Publikováno v: Journal Biomed. 18:10-16
Enzyme activity at the digestive tract level was experimentally studied on rabbits and mini-pigs. The enzyme activity in the blood flow supplied to and from the rabbit stomach and intestines was assessed. In rabbits, the arteriovenous oxygen differen

Publikováno v: Moscow University Bulletin. Series 4. Geology. 1:50-58
Three series of experiments were carried out to study the possibility of replacing quartz sand in the initial charge for the production of glass with a silica clay. The experiments were carried out at atmospheric pressure and temperatures of 900–12
