Abstract: The present description relates to a flat heat exchanger of the types which use a single working fluid circulating continuously through the inside of one or a plurality of heat transmission conduits for cooling one or more electric or electronic components or the like located in a position close to or in contact with a region of the outer part of at least one heat transmission conduit.

Abstract: The present invention provides designing and synthesizing monomer, polymer, or multimer and formulations of amino-acid chains and peptides from SARS-CoV-2 which are subjected to specific peptide-backbone modifications after being screened by a rational selection which has proven to be highly antigenic and immunogenic useful for human antibody detection and stimulation in higher vertebrates as vaccine components.

Abstract: The invention relates to a liquid-semiconductor neutron detector characterised in that it comprises a hybrid structure consisting of a solid phase and a liquid phase, where the solid phase comprises a substrate of a semiconductor material characterised in that it has a series of grooves along the surface of one of the faces thereof forming an electrode of the detector, and where the liquid phase is contained in said grooves and characterised in that it comprises at least one neutron converter compound containing at least one isotope that is able to capture neutrons and replace them with charged particles suitable for ionising the semiconductor material. The invention also relates to the method for producing said detector and to the use thereof.

Abstract: A radiation detector is disclosed. The detector has an entrance opening etched through a low-resistivity volume of silicon, a sensitive volume of high-resistivity silicon for converting the radiation particles into detectable charges, and a passivation layer between the low and high-resistivity silicon layers. The detector also has electrodes built in the form of vertical channels for collecting the charges generated in the sensitive volume, and read-out electronics for generating signals based on the collected charges.

Abstract: The invention relates to a digital system (1) for performing stereotaxic biopsies with a biopsy needle. The inventive system (1) comprises a series of devices which are used to: emit X-rays, detect and transform X-ray photons into electric signáis, position a tissue sample between the X-ray source and the detector, process the electric signáis, and genérate images. The system can also be equipped with a series of devices complementary to those mentioned above, as well as a means for positioning the aforementioned devices in two positions and obtaining images in two different orientations.
