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: The present invention relates to alternative equipment for solar energy prospecting with a focus on low cost, low complexity in installation, operation and maintenance, and high reliability. A low-cost solarimetric station consists of compact equipment capable of providing global irradiance measurements and estimates for direct and diffuse components, as well as hemispheric photographs, with acceptable levels of uncertainty. The pyranometer periodically provides global irradiance information to the system, and the camera records photos of the sky. Using machine learning algorithms, and based on that information, the equipment provides estimates for direct and diffuse irradiance components. The equipment has other meteorological sensors, GPS, and wireless communication facilities. The equipment has an energy supply and management system consisting of a photovoltaic module, charge controller, and battery, which provide the energy necessary for the station to operate.

Abstract: The present invention relates to the use of compounds for imparting a temperature regulating effect to a textile and methods of manufacturing a temperature regulating textile. The present invention also relates to a method of manufacturing a temperature regulating textile, wherein the textile forms part of a non-apparel article. Compounds for imparting a temperature regulating effect on a textile are also described.

Abstract: A method for recovering solder from solder coated scrap pieces includes a step of containing a quantity of solder coated scrap pieces within a centrifuge receptacle of a first centrifuge. The centrifuge receptacle has perforation holes and is rotatably mounted about a first centrifuge axis. A solder collection container surrounds the centrifuge receptacle. The method further includes the steps of heating the solder coated scrap pieces and melting the solder thereon with a heater surrounding the solder collection container and with a drive system, rotating the centrifuge receptacle while the first centrifuge axis is in about a horizontal position at a low speed and tumbling the scrap pieces along a longitudinal length of the centrifuge receptacle, and later rotating the centrifuge receptacle at a high speed for centrifugally extracting molten solder from the centrifuge receptacle, radially outwardly through the perforation holes into the solder collection container.
