Powder Technology, 2005
Abstract Circulating fluidizing system of binary Geldart C powders and Geldart A particles was formed, and was called a circulating powder-particle fluidized bed (CPPFB). Solid residence in the CPPFB was concerned in two aspects, namely, bed turnover time and average turnover time of fine powders.

Altered biochemical markers of bone turnover in humans during 120 days of bed rest
Bone, 2000Microgravity induces significant and progressive bone loss in both humans and animals. This is the consequence of disturbed bone remodeling. We performed a bed rest experiment to simulate microgravity and tried to clarify bone metabolism by measuring biochemical markers of bone turnover. Six healthy volunteers participated in 120 days of bed rest.

Effect of bed rest during pregnancy on bone turnover markers in pregnant and postpartum women
Bone, 2007The aims of our study were to evaluate the changes in bone turnover markers during pregnancy and puerperium as a longitudinal study and to elucidate the effect of bed rest during pregnancy on bone turnover markers in pregnant and postpartum women.The study population comprised 27 Japanese pregnant women aged 23-40 years.

Granular motion in rotating drums: bed turnover time and slumping–rolling transition
Powder Technology, 2002Theoretical models are presented for calculation of the bed turnover time in both the slumping and rolling modes and the slumping-to-rolling transition in rotating drums with less than 50% volumetric fill of free-flowing granular materials. It is suggested that the transition from slumping to rolling occurs when the two turnover times are equal.

Bed Rest Decreases Whole-Body Protein Turnover in Post-Absorptive Man
Clinical Science, 19961. Whole-body protein turnover was measured using the [15N]glycine tracer technique in 10 post-absorptive healthy volunteers during normal daily activities and a period of bed rest. 2. Bed rest reduced whole-body protein turnover (25%), synthesis (26%) and breakdown (25%), but short-term urinary nitrogen excretion remained unchanged.

Changes in bone turnover markers during 14-day 6� head-down bed rest
Journal of Bone and Mineral Metabolism, 2003Osteoporosis caused by exposure to microgravity represents a serious clinical concern, but the mechanisms have yet to be fully elucidated. The present research aimed to elucidate the effects of microgravity environments on bone turnover, with a specific focus on changes in bone resorption markers such as type I collagen cross-linked N-telopeptides (NTx)

The impact of the Community Care Act on bed turnover in a rehabilitation unit
Clinical Rehabilitation, 1995A significant proportion of hospital beds is usually occupied by patients awaiting placement, home adaptations or other care provisions by Social Services. Anecdotal evidence suggests that the number of 'acute bed-blockers' has fallen since the implementation of the Community Care Act (CCA).

Biochemical parameters of bone turnover during ten days of bed rest and subsequent mobilization
Bone and Mineral, 1991Immobilization is associated with increased bone resorption. To investigate the early onset of increased bone resorption, we evaluated 14 patients who were immobilized for 10 days because of lumbar disc protrusion. The fasting urinary hydroxyproline/creatinine ratio increased significantly after four days (P less than 0.01), reached a peak after 10 ...

Deep Sea Research Part B. Oceanographic Literature Review, 1986
Samples of sediments from Australian seagrass (Zostera capricorni Aschers.) beds were taken in June to August 1983 (forN experiments) and November 1982 to January 1983 (N experiments). The ammonium pool turned-over every 0.4 to 0.8 d, as determined with aN isotope-dilution technique.
