Osmotic reflection coefficient
… concentration generates a net volume flux called osmotic flow. The simple case is of the ideal semi-permeable membrane which completely excludes the solute. The flow through such a membrane is directly proportional to the thermodynamic pressure drop less the osmotic pressure drop. For membranes …

Microfluidic Electro-osmotic Flow Pumps
… developed thin film technologies, an electroosmotic flow (EOF) pump was incorporated in a microfluidic liquid chromatography device. An EOF pump was chosen because of its simple design and small size. EOF pumps fabricated on silicon and glass substrates were evaluated. The experimental flow …

Numerical Simulations in Electro-osmotic Flow
… driving mechanism that exists in electro-osmotically generated flow with large channel diameter-to-Debye length ratios (Z). The physics of the flow field were compared between the moving wall model (MWM) and electro-osmotic flow (EOF) at Reynolds numbers of 1 and 1800, and Z > 2500. Also, …

Bioresorbable Osmotic Pump for Long–term Contraception
… Here, we investigated a fully bioresorbable osmotic pump system that provides over 1.5 years of contraception. Osmotic pump systems are recognized for their capacity to provide near zero-order drug release kinetics coupled with immediate drug release cessation upon completion of osmotic …

Thermally Developing Electro-Osmotic Convection in Circular Microchannels
<p>Thermally developing, electro-osmotically generated flow has been analyzed for a circular microtube under imposed constant wall temperature (CWT) and constant wall heat flux (CHF) boundary conditions. Established by a voltage potential gradient along the length of the microtube, the …

Myceloid cell formation in Arthrobacter globiformis during osmotic stress
… was found to form myceloids when subjected to osmotic stress. Addition of known osmoprotective compounds did not relieve this effect. Since myceloid formation may result from altered penicillin-binding proteins (PBPs), PBP profiles of stressed and unstressed A. globiformis were studied. Eight …

The osmotic stress response of ale and lager yeast
… and physical stress during the brewing process. Osmotic stress is evident at discreet points throughout this industrial process, yet the impact of this stress on yeast tolerance, defence and repair has not been investigated. Haploid strains of Saccharomyces cerevisiae exhibit different tolerances …

Glucose dynamics in rat skeletal muscle : recovery from osmotic stress
… kinetics in rat skeletal muscle during iso-osmotic recovery from hyper- and hypo-osmotic stress. Rat EDL muscles were incubated for sixty minutes in either HYPO (190 mmol/kg), ISO (290 mmol/kg), or HYPER (400 mmol/kg) media (Sigma medium-199, 8 mM glucose) according to an established in …

Resource Recovery By Osmotic Bioelectrochemical Systems Towards Sustainable Wastewater Treatment
… development. An innovative treatment concept - osmotic bioelectrochemical system (OsBES), which is based on cooperation between bioelectrochemical systems (BES) and forward osmosis (FO), has been introduced and studied in the past few years. An OsBES can accomplish simultaneous treatment of …

Regulation of Protein Turnover during Hyper-osmotic Stress in Skeletal Muscle
… of this study was to examine the effect of hyper-osmotic stress on protein turnover in skeletal muscle tissue using an established in-vitro model. Rat EDL muscles were incubated in either hyper-osmotic (400 ± 10 Osm) or isoosmotic (290 ± 10 Osm) custom-modified media (Gibco). …

Understanding Protein -Nucleic Acid Recognition: Probing With Osmotic and Hydrostatic Pressure
This work demonstrates the usefulness of combining high pressure techniques with theoretical calculations. Through the use and development of high pressure methods, a better understanding of the factors involved in site-specific recognition in protein-nucleic acid systems was achieved.
