Abstract: A method for reprojecting images (32, 76) into sinograms (74, 112) includes the steps of recursively dividing a two-dimensional image (32, 76) into sub-images (34, 36, 38, 40) (78, 80, 82, 84) as small as one pixel and reprojecting the sub-images at the same or a smaller number of orientations to form subsinograms (42, 44, 46, 48) (86, 88, 90, 92). These subsinograms (42, 44, 46, 48)(86, 88, 90, 92) are then successively aggregated and processed to form a full sinogram (74, 112). The method uses two algorithms to aggregate the sub - sinograms. In one algorithm, the aggregation is exact, and in the other algorithm, aggregation is an approximation. The first algorithm is accurate, but relatively slow, and the second algorithm is faster, but less accurate. By performing some aggregations with the exact algorithm and some aggregations with the approximate algorithm, switching between the two algorithms in one of a numb er of suitable ways, an accurate result can be obtained quickly.

Abstract: The present invention provides a method for producing a vaccine against cancerous diseases, and the vaccine itself. This method involves first using one or more antibodies that are specifically effective against one or more antigens specially expressed by the tumor cells to select one or more mimotopes of said antigens from a phage peptide library. To obtain the vaccine, said mimotopes are conjugated to a macromolecular carrier singly or multiply in the form of their mono-, di-, tri- or oligomers.  When administered, the inventively produced vaccine leads to a humoral immune response and thus to the formation of an active immunity as a consequence of vaccination.

Title: A system and method for uniaxial compression of an article, such as a three-dimensionally printed dosage form
Inventor: PRYCE LEWIS WENDY E
IPC: A61K47/32
Filed: 2002-10-29
Granted: 2012-03-20
Abstract: A uniaxially compressed dosage form manufactured by three-dimensional printing that preserves the predetermined internal architecture of the dosage form while producing an improved surface finish. The compression compacts the dosage form, eliminating at least some of the void space that remains at the end of conventional three-dimensional printing. Surface finish obtained as a result of the uniaxial compression process can be essentially equal to that obtained from conventional tablet pressing. Additionally, the internal structure or spatial variation of composition of the dosage form is preserved during the pressing operation, with geometric shrinkage occurring mostly in the direction of the axis of pressing. Further, as a result of compression, a greater quantity of API can be packed into a given final volume of dosage form.

Abstract: A retaining wedge for concrete forms has a tapered body of generally trapezoidal or triangular configuration. Oppositely diverging side edges of the body are provided with alternating peaks and valleys so as to present a number of detent-like depressions that encourage a firm and secure gripping action when the wedge is driven into the retaining slot of a locking pin that interconnects a pair of adjacent form panels. The peaks and valleys along each edge are presented by alternating convex and concave intersections between successive edge portions that slope outwardly at different angles from one another. Although certain portions of the edge slope outwardly at a higher angle than others, no edge portions slope inwardly toward the longitudinal axis of the wedge body. Consequently, the wedge is constantly tapering over its full length from one end to the other. A long, slender tip of the wedge facilitates insertion and fast starts.
