These workers also noted that spermatozoa motility had decreasing trend as osmotic pressure increased or decreased from 300 mOsm/kg in tris extender.
This example illustrates dilution of solute in the vascular space caused by excess free water intake; osmotic pressure in the cell then increases, causing a shift of fluid to the cell and cell swelling.
The osmotic pressure created in the interstitium by the presence of these large molecules draws water from the circulation.
In Digitaria eriantha, both EG and FPG also decreased at high osmotic pressures, indicating a sensitivity to severe drought.
We can see from equation below that release rate from osmotic system is inversely proportional to membrane thickness: dM/ dt = A, hK[pi]C where dM/dt is drug delivery rate, A and h are the membrane area and thickness respectively, C is the concentration of compound in the dispersed fluid (soluble fraction of the drug), [pi] is the osmotic pressure of the system, and K is the equation constant.
This may be of fundamental importance to deep-sea adaptation, because analyses of deep-sea bony fishes have revealed that TMAO contents increase with depth (16), (17), resulting in an increase in internal osmotic pressure.
Forward osmosis or 'manipulated osmosis' or just 'osmosis' are terms used to describe a natural phenomenon, whereby a solvent flows from a region of lower osmotic pressure across a selectively permeable membrane to an area of higher osmotic pressure.
These conditions will produce cardiogenic pulmonary edema whenever they cause the pulmonary capillary wedge pressure to exceed the value of the colloid osmotic pressure in the pulmonary capillaries, which normally is around 25 mm Hg.
Back to the osmotic pressure theory of double layer, vertical swelling pressure was strongly dependent on the mid-plane potential which is a function of soil properties (specific surface and cation exchange capacity), water electrolyte properties (cation concentration, dielectric constant, valence of cation), and the distance between the platelets (which could be obtained either from void ratio or dry density) [3,4].
An EC of 1 dS/m will have an osmotic pressure of 36kPa (Marshall et al.
In tadpoles, tolerance to extreme osmolarity conditions is asymmetrical; they can survive in diluted media or even in distilled water for long periods of time (Salibian, 1977; Zamorano and Salibian, 1994), whereas their tolerance to concentrated electrolyte solutions is near the osmotic pressure limit of the extracellular medium (Schrock and Hanke, 1979) by means of adaptive adjustment mechanisms (Balinsky, 1981; Gasser and Miller, 1986; Padhye and Ghate, 1992; Warburg and Rosenberg, 1990).
VIII Salt gradient energy in the form of osmotic pressure equal to 240 metre head, exists at the estuary between sea water and river water.
