The effectiveness of a scatter correction approach based on decoupling absorption and scattering effects through the use of the radiative transfer theory to invert a suitable set of measurements is studied by considering a model multicomponent suspension. The method was used in conjunction with partial least-squares regression to build calibration models for estimating the concentration of two ...

We develop a fully continuous model for colloidal suspensions with hydrodynamic interactions. The Navier-Stokes Phase-Field Crystal model combines ideas of dynamic density functional theory with particulate flow approaches and is derived in detail and related to other dynamic density functional theory approaches with hydrodynamic interactions. The derived system is numerically solved using adap...

Simulations of elliptic particulate suspensions in the planar Poiseuille ow are performed by using the lattice Boltzmann equation. E ects of the multi-particle interaction on the lateral migration and rotational motion of both neutrally and non-neutrally buoyant elliptic particles are investigated. Low and intermediate total particle volume fraction fa = 13%, 25%, and 40% are considered in this...

Cellular changes were followed in lung cell suspensions after 175 day inhalation by rats of concentrations 30 mg/m3 or 60 mg/m3 of amosite asbestos every second day combined with daily exposure to cigarette smoke at 30 mg of total particulate matter (TPM)/m3 air. Concomitantly, lung inflammation was assessed by changes in the bronchoalveolar lavage fluid (BALF). A dose-dependent rise in the BAL...

Soluble and particulate complement-fixing antigens of Rickettsia sennetsu were prepared from spleen suspensions of mice infected with the rickettsia and treated with cyclophosphamide. The medium used during purification of antigens, a solution consisting of equal volumes of phosphate-glutamate-sucrose buffer and veronal-buffered saline, was suitable for obtaining antigens with high titers and n...

Mammalian liver contains a heme protein which from its spectrum and properties in particulate preparations has been termed cytochrome b, by Yoshikawa (I), cytochrome m by C. F. Strittmatter and Ball, who localized it in microsomes (2,3), and cytochrome bg by Chance and Williams (4). In view of the fact that this and other microsomal enzymes have been studied chiefly in particulate suspensions, ...
