BACKGROUND The U.S. Air Force (USAF) active duty and civilian populations experience a substantial number of lost-workday injuries while lifting, handling, and carrying objects. Back injuries are most frequently reported. PURPOSE The purpose of this study is to describe the hazard scenarios of lift-handle-carry injuries to better identify effective countermeasures. METHODS The data were der...

Tissue Engineering (TE) bears potential to overcome the persistent shortage of donor organs in transplantation medicine. Additionally, TE products are applied as human test systems in pharmaceutical research to close the gap between animal testing and the administration of drugs to human subjects in clinical trials. However, generating a tissue requires complex culture conditions provided by bi...

In this article a hydrodynamic and rheological analysis of a continuous airlift bioreactor with high-cell-density system is presented. A highly flocculating recombinant strain of Sacharomyces cerevisiae containing genes for lactose transport (lactose permease) and hydrolysis (beta-galactosidase) was exploited to ferment lactose from cheese whey to ethanol. The magnetic particle-tracer method wa...
