Abstract: An ingestible pill platform for colon imaging is provided, designed to recognize its entry to the colon and expand in the colon, for improved imaging of the colon walls. On approaching the external anal sphincter muscle, the ingestible pill may contract or deform, for elimination. Colon recognition may be based on a structural image, based on the differences in diameters between the small intestine and the colon, and particularly, based on the semilunar fold structure, which is unique to the colon. Additionally or alternatively, colon recognition may be based on a functional image, based on the generally inflammatory state of the vermiform appendix. Additionally or alternatively, pH, flora, enzymes and (or) chemical analyses may be used to recognize the colon. The imaging of the colon walls may be functional, by nuclear-radiation imaging of radionuclide-labeled antibodies, or by optical-fluorescence-spectroscopy imaging of fluorescence-labeled antibodies.

Abstract: A composition of matter including a star-like high polypropylene (SHPP), the polypropylene manufactured by a continuous reactive process at molten phase and characterized by a comb-like, fork-like and/or star-like molecular structure, including polypropylene, ranging from about 80 to 99% of formula, free-radical initiator having T1/2 of at least 1 min at temperature higher than 100° C., ranging from about 0.01 to 2% of formula, one or more branching nucleus monomers (BMN) having two or more vinyl or allyl reactive groups, adapted to form at least one branch point when grafted onto the polypropylene, ranging from about 0.1 to 20% of formula, and one or more monomers having at least one vinyl or allyl reactive group, ranging from 0 to about 20% of formula.

Abstract: A novel process for modification of polyolefines and their copolymers thereof, enables the production of modified PP with minimal deterioration of molecular weight and low gel content PE and their copolymers and with minimal yellowness. The novel compound is comprised of polyolefin resin or a mixture of resins, unsaturated acidic monomer and organic peroxide, together with low volatility polar acrylic co-monomer and low softening point resin, in a continuous reactive reactor The novel process minimizes sublimation of maleic anhydride and improves distribution of monomers and initiator prior to the melting of the polyolefin.

Abstract: A reactive fine particle includes one or more functional compounds A or its precursors having a maximal size of less than 2 microns, adapted for synthesis, modification, curing, cross-linking, secession and/or initiating of polymerization of polymers; and one or more inert particles B having at least the maximal size of 2 microns and carrying said functional compounds A at its outer surface and/or in its inner portion. The compounds A to inert particles B weight ratio is ranging from 0.01A:100B to 50A:100B.

Abstract: Liquid thermosetting ink for ink-jet applications includes at least a resin, at least one solid latent curing agent having a maximal particle size of less than 2 microns and an inert filler having fine particles. The single-pack or two-pack ink has a viscosity lower than 50 Cp at the application temperature, a surface tension lower than 80 dyn/cm at the application temperature, and a glass transition temperature of cured ink of greater than 120° C.

Abstract: The present invention concerns treated fibrous porous material having a defined nanostructure comprising reactive sites thereon, wherein said fibrous porous material is treated with a low viscosity organic solution comprising organic solvent, isocyanate component unsaturated resin and optionally additional additives. The treated fibrous porous material is further mixed with a resin to form a composite. The composite may be formed by various methods of mixing and molding. The invention is further directed to various composites made therefrom. The fibrous porous material is selected from the group comprising cellulose, lignin, synthetic ceramics, porous metal nanopowders, kaolin, bio fibers and porous powders of biological origin or their mixtures. The resin may be any polymer virgin or scrap obtained from industrial or domestic waste, and is selected from thermoplastic or thermosetting polymers.
