Abstract: A system automatically calculates drug infusion applicable to a patient to induce a satisfactory anesthetic state during surgery. The automatic calculation system would be determined by target values of physiological monitors to evaluate the patient's condition. Automatic infusion increases patient safety, reducing post-surgical morbidity and mortality, and reduces continuous decision-making by the specialist. An electronic system implements a MIMO-PID controller that calculates the infusion of various drugs on the basis of a control error defined by deviations in the patient's condition, which is analyzed by several monitors. The automatic drug infusions are determined by safety systems for preventing under and/or over infusion events and are complemented with correction and feedback systems.

Abstract: A multiband resonator element which, on the one hand, compensates the components of an electromagnetic field radiated from its phase centre, located on the axis of symmetry of the resonator, to control the polarization purity of a radiating element. On the other hand, it enables the selection of the electromagnetic fields reflected and transmitted on a frequency- and multiband-selective surface. In this sense, this is an innovative element that enables the design of directive radiating elements and with an axial ratio for its circular polarization less than or equal to 1.5 dB for all the angles belonging to the hemisphere centred on broadside. Thus, it can be used in the design of reflectarrays, transmitarrays and any dichroic multiband surface, likewise on metamaterial surfaces.

Abstract: This invention is, in general, related to the technological field of packaging of vegetable products, such as whole fresh fruits and vegetables that tend to have certain surface microbial load. Specifically, this invention relates to a new cardboard packaging which is characterised by having an antimicrobial active coating based on a polymeric compound in combination with essential oils forming inclusion complexes with cyclodextrins. Vapours of essential oils are emitted from the cardboard as sufficiently high relative humidities are reached in the vicinity of this coating which is next to the packed product, and these vapours have an antimicrobial action against fungi, yeasts and bacteria, which both spoil product quality and are pathogenic for consumers. This new packaging significantly achieves increasing food safety and the shelf life of foods packed therein.

Abstract: A method of molecular self-assembly is disclosed using two interacting streams that are allowed to interact and are subsequently forced through an orifice. A first stream of a dope solution of polymer molecules is extruded out of a capillary. The dope stream is surrounded by a focusing fluid which is miscible with the dope solution. The interaction between the jet of dope solution and surrounding focusing fluid creates hydrodynamic stretching and allows for extracting solvent from the dope solution. Concentrated polymers within the solution at stretched regions of the jet interact, and finally self-assembly takes place after the fluids are forced through the outlet of a converging nozzle. The formation of the structure can be optionally completed in a coagulating space. The structures thus obtained such as fibers or threads can be wound onto a mandrel.
