Red deer (Cervus elaphus), like other ruminants, excrete approximately 70% of the nitrogen they ingest. Developing ways in which to reduce the rate of loss, such as manipulating the diet or selecting for efficiency of growth, requires close monitorin

Education differences in sickness absence and the role of health behaviors: a prospective twin study
Publikováno v:
BMC Public Health, Vol 20, Iss 1, Pp 1-11 (2020)
Abstract Background Long-term sickness absences burden the economy in many industrialized countries. Both educational attainment and health behaviors are well-known predictors of sickness absence. It remains, however, unclear whether these associatio
