Abstract: Provided are Ti(C,N)-based cermets with Ni3Al and Ni as binder and a preparation method thereof. The Ti(C,N)-based cermets are prepared by raw materials subjected to ball-mill mixing, die forming, vacuum degreasing and vacuum sintering, wherein weight percentage of each chemical component of the raw materials is as follows: TiC 34.2˜43%, TiN 8˜15%, Mo 10˜15%, WC 5˜10%, graphite 0.8˜1.0%, Ni 20˜24%, and Ni3Al powder containing B 6˜10%. Ni powder and Ni3Al powder containing B are used as binder. The Ti(C,N)-based cermets feature in excellent corrosion resistance, oxidation resistance and mechanical properties at high temperature, has a hardness of 89.0˜91.9 HRA, a room temperature bending strength of 1600 MPa or more, and a fracture toughness of 14 MPa·m1/2 or more, and is applicable for manufacturing high-speed cutting tools, dies and heat-resisting and corrosion-resisting components.

Abstract: A computer-based method for diagnosing a region of interest within an anatomical structure having the steps of receiving a 3D volumetric representation of the anatomical structure, and identifying at least one volume of interest and volume of normal of the anatomical structure. A first feature set can be generated based on a density, a gradient and a curvature of the volume of interest, and the first feature set can be compared to a second feature set to diagnose the region of interest to at least one a plurality of pathology types.

Abstract: A method for producing foams containing biological materials is described. A solid or semi-solid paste is formed by combining biologically active material with a protecting agent in an aqueous solvent. The paste formed is allowed to set, and may optionally then be apportioned into the desired shape. The paste may be frozen to allow formation of ice crystals to act as porogens. Subsequently, the paste is exposed to travelling wave radiant energy under vacuum (t-REV) for drying. This causes the solvent to boil off, leaving dried material containing the biologically active material, the protecting agent, and a relatively low water content. Biologically active materials which can be used include cells, microbial cultures, live attenuated microbes, probiotics, yeasts, enzymes, vaccines, proteins, and any heat-sensitive biological material. By directing energy via a travelling wave through a sample, good control of temperature and process conditions can be achieved.

Abstract: An antimicrobial composition and a method for administering the antimicrobial composition through the water or feed of livestock, wherein the antimicrobial composition is made up of lysozyme and various other agents that act synergistically with lysozyme, such as, dried egg powder, albumen, a sequestering agent and/or a lantibiotic. The composition is used to inhibit the growth of, and diseases and epidemiological significant effects caused by, Clostridium perfinigens, E, coli and Salmonella, in the gut of livestock. More particularly, the antimicrobial composition and method relate to a feed additive that can be administered to poultry and/or swine through their feed. The use of such a feed additive may also inhibit other enteric pathogens that may be present in the gut of livestock.
