Abstract: The gel compositions as described herein, are less affected by changes in humidity, are readily formed into complex shapes, and can contain high loadings of the hydrophobic material, even when the material is not highly hydrophobic, and provide a more controlled release of the hydrophobic material.

Abstract: The gel compositions as described herein, are less affected by changes in humidity, are readily formed into complex shapes, and can contain high loadings of the hydrophobic material, even when the material is not highly hydrophobic, and provide a more controlled release of the hydrophobic material. It is believed that the slow release is achieved by forming the gel to have a tight cross-linked network with small pore-size. The pore size is correlated to the average correlation length as measured using Small Angle X-Ray Scattering (SAXS). By limiting the average correlation length to less than 8 nm, preferably from 0.3 nm to 8 nm, more preferably from 0.3 nm to 4 nm, a long lasting release of the hydrophobic material is achieved, rather than a blooming effect, whereby the hydrophobic material is released in a short burst.

Abstract: Described are embodiments for determining components of a composite liquid and controlling the flow of the components into containers. In one embodiment, components of whole blood, after separation, are determined and directed to different containers for collection and storage. Embodiments may be implemented on an apparatus configured to separate multiple discrete volumes of composite liquid (e.g., whole blood) into components.

Abstract: Data that represents chemical structures, and fragments thereof, are transformed into corresponding molecular keywords comprising letters and numbers that are associated with the original data representation. These molecular keywords encode the structural features of a given chemical structure. Molecular keywords are generated for linear structures, branching points, adjacent branching points, monocyclic, polycyclic and macrocyclic ring systems, stereo centers, ring-substituent patterns and molecular-formula atom counts. Indexing, database searching, and Web page presentation can be provided in conjunction with the molecular keywords representation.

Abstract: A centrifuge apparatus for processing blood comprising a bottom spring-loaded support plate; a top support plate; an axial inlet/outlet for blood to be processed and processed components of the blood, the axial inlet/outlet being attached to the top support plate by a rotating seal assembly; a variable volume separation chamber mounted between the bottom support plate and the top support plate, the variable volume separation chamber being fluidly connected to the axial inlet/outlet; a pump fluidly connected to the axial inlet/outlet; and a rotary drive unit attached to the bottom support plate. The top support plate is fixed vertically and the bottom spring-loaded support plate is mounted on springs that maintain pressure on the variable volume separation chamber and allow the bottom support plate to move vertically.
