background; various industries produce and discharge wastes containing different heavy metals into the environment. apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. method; the cadmium (cd) (ii) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of aspergillus versicolor were examined as...

We analyzed the effects of gravitational unloading on muscular fatigability and the effectiveness of resistive vibration exercise to counteract these changes. Changes in knee extensor fatigability as a consequence of 8 weeks of horizontal bedrest with or without daily resistive vibration exercise were evaluated in 17 healthy male volunteers. Bedrest increased fatigability (% decrease in maximal...

Coralline algal (maerl) beds are widespread, slow-growing, structurally complex perennial habitats that support high biodiversity, yet are significantly understudied compared to seagrass beds or kelp forests. We present the first eddy covariance (EC) study on a live maerl bed, assessing the community benthic gross primary productivity (GPP), respiration (R), and net ecosystem metabolism (NEM) d...

BACKGROUND After striking changes in rates of sudden unexplained infant death (SIDS) around 1990, four large case-control studies were set up to re-examine the epidemiology of this syndrome. The European Concerted Action on SIDS (ECAS) investigation was planned to bring together data from these and new studies to give an overview of risk factors for the syndrome in Europe. METHODS We undertoo...

This month, we focus on current research in bed rest in pregnancy. Dr. Lorenz discusses four recent publications, and each is concluded with a "bottom line" that is the take-home message. The complete reference for each can be found in on this page, along with direct links to the abstracts.

This work studied the influence of effluent recirculation upon the kinetics of anaerobic degradation of dairy wastewater in the feedless phase of intermittent upflow anaerobic sludge bed (UASB) reactors. Several laboratory-scale tests were performed with different organic loads in closed circuit UASB reactors inoculated with adapted flocculent sludge. The data obtained were used for determinati...

I n t e r v e n t i o n Patients were allocated to bed rest (n = 84), physiotherapy (n = 83), or continuation of ADLs (n = 83). Bed rest could be done at home or in the hospital and lasted 7 days. Physiotherapy sessions were scheduled twice weekly for 4 to 8 weeks and involved segmental mobilization, disc unloading and loading exercises, and hydrotherapy. Patients in the continuation-of-ADLs gr...

For many years, average bed occupancy level has been the primary measure that has guided hospital bed capacity decisions at both policy and managerial levels. Even now, the common wisdom that there is an excess of beds nationally has been based on a federal target of 85% occupancy that was developed about 25 years ago. This paper examines data from New York state and uses queueing analysis to e...
