A method and device for non-invasive real-time control of inner body temperature variables during therapeutic cooling or heating using computer simulations, machine learning and control techniques. The invention refers to a method and device that enable control of inner body temperatures according to different therapeutic protocols. The technical problem that the invention solves is the control of inner body temperatures (hidden temperatures) that are difficult or impossible to be measured. In that context, a predictive model is used to estimate (predict) the values of the controlled inner temperature variables based on smaller number of other variables whose measurement is more feasible, i.e. temperatures on the body surface. However, simulations are usually resource and time consuming. The predictive model is constructed using advanced methods for data analytics to capture the correlation between the hidden variable and the measurable ones in data resulting from preliminary computer simulation of the system for different input simulation parameters.

This invention relates to bonded magnets and the method for their production. Such magnets benefit from the fact that for binding, they utilize Low-Melting-Point metal or an alloy, and thus can be used at temperatures where conventional bonded magnets cannot operate. This composite magnet is made of magnetic phase and non-magnetic metallic binder. The mechanical and magnetic properties of metal-bonded magnets vary with the ratio of the two phases. The optimum result is achieved when adding 20-40 wt. % of binder. A huge difference can be observed between conventional and spark-plasma sintering (SPS) processing. An increase in remanence is up to 30%, as a consequence of simultaneous application of pressure and temperature. Additionally, minimized exposure time contributes to preservation of magnetic properties, which is a strong advantage of SPS technique. The value added of such magnets is the ability to withstand temperatures above 200° C., due to metallic matrix.

Subject of the invention is a process that allows the control of lactic acid fermentation of wine and is based on the use of magnetic particles. The production of wine is based on fermentation of must, which covers two fermentation processes; alcohol fermentation and lactic acid fermentation. Lactic acid or secondary fermentation, which usually begins after alcoholic fermentation, is a desirable process, as it reduces the acidity of the wine, strengthens the organoleptic characteristics of the wine and improves the microbiological stability of the wine. For known processes, acid-acid fermentations with addition of lactic acid bacteria, such as Oenococcus oeni, to must. Lactic bacteria convert malic acid into lactic acid and carbon dioxide. A technical problem that is not satisfactorily solved is the control of the process of lactic acid fermentation and the removal of lactic acid bacteria from the wine after lactic acid fermentation. Lactic acid bacteria multiply in the process of lactic acid fermentation and usually completely alter the substrate of malic acid into a product of lactic acid. When they run out of the primary substrate, malic acid, they begin to metabolize other substances into the wine, which can have a significant negative effect on the taste of the wine. It is an object and object of the present invention to enable the control of lactic acid fermentation by isolating lactic acid bacteria from the wine at the appropriate stage of the lactic fermentation process or after completion of lactic acid fermentation. By eliminating bacteria, fermentation processes stop. The elimination of lactic acid bacteria is achieved by irreversible adsorption of magnetic particles onto their surfaces, which enables their removal from the must by using an external magnetic field.

13 protein mushroom extracts and 1 protein extract from mycelium with antibacterial activity against R. solanacearum have shown activity in tests. Moreover, an A. phalloides protein fraction also completely inhibited bacterial growth. The extracts and fractions not only displayed potent inhibition of bacterial multiplication but more commonly displayed bactericidal effect, rather than bacteristatic. In vivo testing of 5 selected extracts on tomato and potato plants lead to a conclusions, that C. geotropa, S. variegatus and T. saponaceum extracts lower disease occurrence and delay bacterial wilting on both tomato and potato plants. Thus, mushroom protein extracts of the present invention are an important tool to treat bacterial wilt caused by R. solanacearum. Moreover inhibition of 12 R. solanacearum strains as well as R. mannitolilytica and E. coli by mushroom protein extracts proves their broad spectrum activity, which could be beneficial in the fields of medicine, biotechnology, waste management/bioremediation and agriculture.

The device for generating UV radiation, providing primarily UV A and UV B radiation with a minimum amount of radiation in the IR region and the visible light region, comprises at least one source tube, which is closed and whose walls are permeable to UV-A and UV-B radiation, while the source tube contains a constant part of sulphur monoxide molecules (SO) and, simultaneously, a constant part of free electrons. The method for generating UV radiation using the device according to the invention lies in the fact that the source tube is filled with SO molecules with a part of free electrons at a defined temperature, pressure, kinetic energy and electron density of the free electrons, while the SO molecules are continuously fed in and fed out to/from the source tube in such a way, that the pressure in the source tube and the part of the free electrons remains constant.

The present invention belongs to the field of silicon photomultipliers based sensor systems, more precisely to the field of processes for extending the usability of sensor systems with silicon photomultipliers in the regime of piled-up pulses of light and devices, which are based on these processes. The extension of the silicon photomultiplier performance into the piled-up regime is made by adding an intermediate step into the measurement of the incident light intensity. This step takes into account the properties of the sensor and dynamically compensates for the gain loss due to temporary inhibition of parts of sensor. On the basis of this estimation the system reports numerically modified estimations for brightness of flashes.

A method is described whereby titanium or titanium alloys are colored in different colours .A processing chamber, such as a quartz tube 1, may be used which is sealed with two gate valves 2,3. The work pieces are arranged in the processing chamber on a sample holder 4. A vacuum is then applied to the chamber 1. Oxygen is then passed into the processing chamber and a magnetic field applied. The method utilises an oscillating magnetic field in a low pressure oxygen-containing atmosphere to initiate titanium oxidation. The oxide layer so produced is thick enough to obtain chosen colour through interferometric effects. Colours range from yellow with the thinnest oxide layer, through to purple, blue, gold, violet, green to grey. No deposition of coatings or anodic oxidation occurs. This can be used for various applications, including: decorative purposes, labelling, protecting the surfaces made of titanium or titanium alloys, and increasing the biocompatibility.

The present invention provides an angle-sensitive camera for detecting radiation, including a stationary detector (1) and a set of simultaneously rotating gamma-ray absorbent obstructions or windows in a cylindrical obstruction element (3), rotating about an axis passing through the detector. Detection of the radiation incident from a given direction is hindered twice per device revolution. There are at least two obstructions in fixed positions at angles between 40 and 50 degrees sweeping through a spherical or cylindrical surface surrounding the detector. The azimuthal and elevation angle of the radiation direction translate uniquely into the exact times of detection hindrance during each revolution.

Novelty: Increasing comparative tracking index (CTI) of electrical devices comprising at least two electrodes electrically insulated with composite material containing glass particles, preferably glass fibers and metallic fillers embedded in polymer matrix, comprises e.g. (a) inserting the electrical devices into a processing chamber, (b) evacuating the processing chamber down to the pressure of 100, preferably 1 Pa, and (c) exposing the electrical devices in the processing chamber to oxygen ions of kinetic energy of 5-80 eV, preferably 10-30 eV. Use: The method is useful for: increasing CTI of electrical devices; modifying an electronic device, where the electronic device comprises a product that comprises insulators, rotors or commutators (all claimed); and improving the CTI performances of the polymer matrix composites by surface modification by means of oxygen plasma treatment. Advantage: The method: provides the CTI without requiring the need of additional polymer (halogenated polymers, phosphorus or nitrogen containing polymers), hence eco-friendly; utilizes the glass fibers embedded in polymer matrix without significant distortion of the bulk properties of insulating material; and utilizes the oxygen ions that do not only cause preferential heating of the surface of composite material containing glass particles, preferably glass fibers, embedded in polymer matrix, but interacts chemically with hydrogenated carbon material from which the polymer is obtained.

The invention refers to an ultrafast quench based nonvolatile bistable device which consists of an active material on a passive or active substrate which changes its physical properties, after exposure to a sufficiently temporally short external perturbation causing an ultrafast quench. The perturbation can be from an external ultrashort laser pulse or ultrafast electrical pulse from an electrooptic device or any other generator of ultrashort pulses. This change of the materials properties can be detected as a change of optical properties or electrical resistance. The dielectric properties can be reverted back to their original state by the application of a heat pulse applied by an electrical heater within the device or an external laser.
