This review article outlines an overview of new trends and modern approaches for practical implementation of magnetic water treatment to eliminate scaling salts (carbonate, chloride and sulfate salts of Ca2+, Mg2+, Fe2+ and Fe3+ cations) in power heat-exchanger devices and pipe lines. The principles of physical effects of the magnetic field on H2O molecules as well as the parameters of physico-chemical processes occurring in water and the behavior of the dissolved in water scaling salts subjected to the magnetic treatment are discussed. It is demonstrated that the effect of the magnetic field on water is a complex multifactorial phenomenon resulted in changes of the structure of hydrated ions as well as the physico-chemical properties and behavior of dissolved inorganic salts, changes in the rate of electrochemical coagulation and aggregate stability (clumping and consolidation), formation of multiple nucleation sites on the particles of fine dispersed precipitate consisting of crystals of substantially uniform size. There are also submitted data on constructive features of various magnetic water treatment devices produced by domestic industry, based on the permanent magnets and electromagnets (solenoids), such as hydro magnetic systems (HMS), magnetic transducers (MT) and magnetic activators (MA) of water. It was estimated the efficiency of using the various magnetic water treatment devices in water treatment technologies.

The key methods for positron annihilation study is: a) identifying spectrum of angle distribution of annihilation photons (URAF) ; the study of temporary distribution spectrums of annihilation photons (VRAF), characterized by intensity and lifetimes ; b) Doppler widening of annihilation line (DUAL), characterized by S parameter – is a correlation of central part of annihilation photopeak to the distribution area of annihilation photopeak. The VRAF method provides data on electronic density where the annihilation positron is located, and URAF and DUAL methods provide data on distribution of impulses and chemical composition of the environment, surrounding nano objects in the area of annihilation. The overview shows that these methods allow to identify the nature and the density of dislocations in semiconductors, as the effective centers for positrons capturing are negatively-charged and neutral dislocations.

There are submitted data on the possibility of applying the Kirlian effect in modeling of non-equilibrium conditions with gas electric discharge simulating primary atmosphere are submitted. The physical basis and technique of visualization of gas discharge luminescence in alternating electric fields of high electrical voltage (5–30 kV) and frequency (10–150 kHz) as well as electrosynthesis of organic molecules are presented. We submitted data on research by colour coronal spectral Kirlian analysis and IR-spectroscopy of water samples of various origin and various degree of water purification and water processing, and also samples of hot mineral, sea and mountain water from various sources of Bulgaria. It was measured the average energy of hydrogen bonds between H2O molecules in the process of cluster formation (dimer, trimer) compiles – 0,10670,0011 eV.

The review article considers the properties of the atom of positronium ( ) of small radius in the excitonic presentation. The key role of this problem is the use of many-electron approach. The use of excitonic presentation of Vanier system + crystal is the best model of the small radius. The natural justification of the approach of the ‘heavy’ small radius and the concerned errors of the annihilation process is possible in the framework of this model. The considered transport mechanisms enable to obtain the number of new valuable results. The most important is that the values can capture the small radius, which is comparable to the experimental values of the annihilation rate. Significantly, crystals with high concentration of defects can annihilate exactly from localized states.

Osteoporosis is a metabolic bone multifactorial disease characterized by increased bone fragility due to a decrease in bone mass and microarchitectural spongy and compact bone tissues. The major complications of osteoporosis are fractures of the hip bone and vertebral bodies, the treatment of which is accompanied by significant difficulties and possible complications in the postoperative period because of the poor bone quality. Particularly acute this problem is the use of bone grafts and prostheses – marked osteoporosis can significantly reduce the osseointegration of materials. To improve the biocompatibility of the implants a lot of techniques used in modern medicine sach as modification the geometry and topology of the implant surface and deposition on the surface of biologically active molecules. One of the most studied compounds, which are used to cover the implants and independently as osteoplastic material is hydroxyapatite. The purpose of our study was to investigate changes in the periimplant area of the distal epiphysis of femur after implantation of nanocomposite material based on chitosan and hydroxyapatite. Implantation of chitosan-apatite nanocomposite material into the distal femoral epiphysis with signs of osteoporosis leads to normalization of trabecular structure and mineral saturation in periimplant zone. Given the data, the apatite-chitosan composite can be considered as the applicant for the surface modification of bone implants.

This paper presents the results of evaluation of possible biophysical methods and approaches for registering various non-ionizing radiation (NIR) wave types of the human body in the electromagnetic range. Many types of NIR (electromagnetic waves, infrared radiation, thermo radiation, bioluminiscence) emitted from the human body were reviewed. In particular the results on of spontaneous biophoton emission and delayed luminescence from the human body are submitted along with infrared thermography (IRT) results. It was shown that 1 cm2 of skin generally emits 85 photons for 1 s. The intensity of biophoton emission ranges from 10−19 to 10−16 W/cm2 (approx. 1–1000 photons.cm-2.s-1). The specific photon emission from part of the human thumb was detected as a spectrum of various colours with the method of Colour coronal spectral analysis on a device with an electrode made of polyethylene terephthalate (PET hostaphan) with applied electric voltage 15 kV, electric impulse duration 10 s, and electric current frequency 15 kHz. It was established that photons corresponding to a red color emission of visible electromagnetic spectrum have energy at 1,82 еV. The orange color of visible electromagnetic spectrum has energy at 2,05 eV, yellow – 2,14 eV, blue-green (cyan) – 2,43 eV, blue – 2,64 eV, and violet – 3,03 eV. The reliable result measurement norm was at E ≥ 2,53 eV, while the spectral range of the emission was within  = 380–495 nm and  = 570–750 nm ± 5 nm. Also were estimated some important physical characteristics (energy of hydrogen bonds, wetting angle, surface tension) of water by the methods of non-equilibrium energy (NES) and differential non-equilibrium energy (DNES) spectrum of water, that helps understand in general how electromagnetic radiation interacts with water and establish the structural characteristics of water.
