Abstract: A characterization device, system, and method for characterizing reflective elements from the light beams reflected in it. The device has two variable-gain detectors on a common structure, which can be portable or fixed, and for capturing light beams reflected by a reflective element, and from at least one processor characterizing the quality of the reflected light beams and evaluating the quality of the reflective element from its reflective capacity. Each detector has a lens for increasing the signal-to-noise ratio of the reflected beam or beams, a light sensor on which the beam or beams captured by the lens are focused, an automatic gain selection system associated with the optical sensor, and a data communication device associated with the device itself. A characterization system and a characterization method for characterizing reflective elements from the quality of the light beams reflected in at least one reflective element or heliostat.

Abstract: A low-erosion radio frequency ion source is disclosed having a hollow body with conductive interior walls that define a cylindrical cavity, with a gas supply inlet for plasma-forming gases and a power supply inlet for injecting radio frequency energy into the cavity; an expansion chamber connected to the cavity by means of a plasma outlet hole; an ion-extraction aperture in contact with the expansion chamber; coaxial conductor disposed in the cavity, parallel to the longitudinal axis thereof, one or both ends of the coaxial conductor being in contact with a circular interior wall of the body, forming a coaxial resonant cavity; the coaxial conductor having a conductive protuberance opposite the plasma outlet hole and which extends radially into the cavity. It substantially reduces the erosion of the conductive materials.

Abstract: The present invention relates to a new humanised animal model of psoriasis. Said model is generated by grafting humanised skin equivalents in the animal, injecting T lymphocytes and cytokines involved in the generation of the disease in humans, and performing the tape-stripping technique in order to generate damage in said grafted equivalents. Said model may be used to study the disease, as well as for the identification and evaluation of the efficacy of compounds against said disease.

Abstract: A concentrated solar radiation assembly comprising a housing divided into segments by housing trusses; window blocks positioned within the segments supported by the housing trusses; and, internal trusses positioned on top of the window blocks and within the segments. The assembly may be hermetically sealed, large-scale and refrigerated by water flow within the trusses.

Abstract: The present invention relates to a humanized, non-human mammal model, preferably a humanized mouse model, with an engrafted portion of human skin having hyper-patient sensitivity to ultra violet (UV) light, and a method for preparing such non-human mammal model and its use for studying acute and long term effects on human skin by exposure to UV light and for testing topically or systematically applied or administered substances for their capability to prevent, repair and/or cure damages of such exposed human skin. This mouse model comprises an engrafted portion of human skin based on skin cells of a human Xeroderma pigmentosum (XP) or Gorlin's Syndrome (GS) patient. XP and GS are rare human autosomal disorders characterized clinically by hypersensitivity to UV light, especially to UVB rays, and high predisposition for developing skin cancers on sunlight exposed skin areas.
