50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Thiosulfate leaching of gold—A review

Minerals Engineering, 2001
Abstract The ammoniacal thiosulfate leaching process for gold and silver extraction has been reviewed in terms of leaching mechanism, thermodynamics, thiosulfate stability, and gold recovery options. The application to different ore types and process options have also been discussed.

Anaerobic thiosulfate leaching: Development of in situ gold leaching systems

Minerals Engineering, 2008
Ferric EDTA and ferric oxalate complexes are both effective oxidants for the aerobic and anaerobic dissolution of gold in thiosulfate solutions, and therefore are potential candidates for the development of an in situ leaching system. The thiosulfate and polythionates were quantified during leaching using HPLC with perchlorate eluent and an anion ...
