Abstract Pressure filtration is receiving increasing scientific and technological interest as a promising forming technique in the field of technical oxide and non-oxide ceramics. In this study various aspects of pressure slip casting of Si 3 N 4 were examined; in particular, slip behaviour, casting curves at different pressures (up to 10 MPa) and ...

Filtration pressure equilibrium: a statistical analysis
American Journal of Physiology-Renal Physiology, 1981Statistical analysis of data in published micropuncture studies was applied to determine: a) the number of rats and samples of glomerular capillary pressure (Pg), end-capillary oncotic pressure (COPE), and proximal tubule pressure (Pt), needed in a single study to state with 95% confidence that a measured mean net efferent effective filtration ...

Screen filtration pressure and pulmonary hypertension
American Journal of Physiology-Legacy Content, 1965A series of experiments was devised to test the resistance to flow through the lungs of blood samples with different screen filtration pressures (SFP). The pulmonary artery and left atrial presures were measured in dogs rendered acutely hypotensive by rapid bleeding, and in others subjected to severe soft tissue trauma. Following acute hypotension the

Autoregulation of effective glomerular filtration pressure
American Journal of Physiology-Legacy Content, 1974The curvilinear relationship between the sieving coefficients for polyvinylpyrrolidone 125I (fractional clearances/GFR) and the molecular radii of hydrodynamically equivalent spheres was studied in 42 normal mongrel dogs under Nembutal anesthesia. The parameters characterizing the porosity of an equivalent isoporous membrane, r (radius of cylindrical ...

Screen Filtration Pressure of Blood--An Evaluation
Cardiovascular Research, 1969The relative importance of some factors in the determination of screen filtration pressure (SFP) of human blood has been examined. The physical determinants of SFP are defined and the effect of time, anticoagulant, red cells, platelets, and leucocytes are established.

Filtration Rates and Pressure Driving Force in AV Filtration
Blood Purification, 2008The whole blood filtration rate of hemofilters were measured in in vitro circuits simulating the pressure and flow conditions of arteriovenous filtration. For all devices tested, filtration rate was found to be independent of blood velocity and wall shear rate but to increase linearly with applied transmembrane pressure according to the following ...

The role of porosity in filtration: IV. Constant pressure filtration
AIChE Journal, 1960AbstractCertain assumptions which have previously served as a basis for the conventional equations employed in constant pressure filtration are shown to be in error. It is demonstrated that the specific filtration resistance, the ratio of the mass of wet to mass of dry cake, and the rate of flow, q = dv/dθ, are not constant as has been assumed.

Pressure filtration of flocculated suspensions
AIChE Journal, 1995AbstractFrom the development of a compressional rheology of a flocculated suspension, a number of separation processes have been modeled. With respect to the two‐stage pressure filtration process of compact formation and then consolidation, the rheological formulation appears at first examination to eb significantly at variance with the conventional ...

Colloid Osmotic Pressure, Filtration, Interstitial Pressure
1969More than a hundred years ago [1859] Claude Bernard (quoted in [363]) recognized the importance of colloids for maintaining a normal BV. The classic work of Starling [1379] at the turn of the century laid the cornerstone for our ideas about oncotic pressure. In general his views are still valid today; he realized that proteins are also able to pass the
