Abstract: A biodegradable based polymers for the production of biodegradable medical applications is provided. The biobased material has a copolymer constituted by dextran modified with glycidyl methacrylate and poly (#-caprolactone) modified with 2-isocyanatoethylmethacrylate, which are combined in different formulations and used to produce membranes, 3-D scaffolds and hollow tubes that can be used as biomedical devices for diverse applications, such as drug delivery systems, tissue engineering scaffolds, repair and regeneration of peripheral nerves, among others.

Abstract: Targeted sequencing of genetic regions that differ between two DNA preparations uses genomic fragment enrichment. This method can be used to study genetic variation among closely related species and microbial communities.

Abstract: Refractory materials (typically refractory bricks) having the exposed working surface treated to form a silica sand glazed surface for their utilization in iron ore reduction reactors, for example of the moving bed type, fluidized bed type, rotary kilns, or the like, and method and apparatus for treating refractory bricks before installation as well as for treating refractory linings already installed in existing iron ore reduction plants, which produce direct reduced iron (DRI), prereduced iron ores, or the like. Some operational problems, involving adherence and buildup of aggregates from small metallic iron particles on the refractory lining of said reduction reactor, are minimized with a corresponding decrease in operating costs and an increase in the availability of the DRI producing plant.
