Cake Collapse in Pressure Filtration

Langmuir, 2001
Aqueous dispersions of latex particles have been aggregated by addition of Ca2+ ions and then filtered in a pressure filtration cell. The filtration cakes have been examined through small-angle neutron scattering, void volume fraction measurements, and permeate flux measurements.

Pressure filtration of Si3N4

Journal of the European Ceramic Society, 1997
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, 1981
Statistical 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, 1965
A 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, 1974
The 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, 1969
The 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.
