   Sammanfattning : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. LÄS MER

4. 3. Influence of oilseed supplementation on ruminant meat and milk with emphasis on fatty acids

   Författare :Tyler Turner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : In the human diet, long-chain polyunsaturated fatty acids (LC-PUFA, ≥ C20) are supplied almost exclusively from animal sources. Red meat represents a significant source of LC-PUFA in many areas of the world. However, the health aspects of consuming ruminant tissues are often viewed critically due to the proportions of saturated fatty acids (SFA). LÄS MER

5. 4. Teenage Kicks – The Differential Development of Drug Use, Drunkenness, and Criminal Behaviour in Early to Mid-Adolescence

   Författare :Russell Turner; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drug use; Drunkenness; Alcohol intoxication; Criminal behaviour; Delinquency; Adolescence; Adolescent development; Risk behaviour; Risk factor; Prevention; Critical realism; realist method; Person-oriented method;

   Sammanfattning : This thesis studies the development of drug use, drunkenness, and criminal behaviour in early to mid-adolescence. Its main aims are to improve knowledge about how and why these three behaviours develop and to contribute towards the development of theory that can have applications in prevention policy and practice. The thesis comprises four studies. LÄS MER
