Abstract: An approach to hyperthermia for cancer treatment based on multiphonon relaxation of optical excitation in rare-earth (particularly Dy3+) doped nanocrystals after laser irradiation allows fast and accurate local heating to a preset temperature. A collection of nanoparticles suitable for use in hyperthermia treatment of cancerous and non-cancerous cells by laser irradiation in the wavelength of the transparency window of biological tissue (800 nm-1300 nm) preferably 800-900 nm is provided, where each nanoparticle comprises a crystalline host structure, and at least one species of rare-earth dopant ion.

Abstract: The invention is directed at the definition of the dynamic movement parameters of a material object during sports competitions or training and makes it possible to improve a judgment objectivity during said sports competitions. A footmark trajectory resulting from the interaction of am object with surrounding objects or environment is recorded in an infrared spectral range. The dynamic of modifications of infrared footmarks in different spectral ranges are recorded. The trajectories of shadows formed by external infrared sources are recorded. The inventive device system comprises an infrared camera, a computer and a mechanical oscillation receiver. Said infrared camera can be provided with a system of optical filters for modifying the spectral range of the sensitivity thereof.
