Magnetic Resonance in Solids | Year: 2017

The angular and temperature dependencies of the electron paramagnetic resonance (EPR) linewidth in the weak constant field and of the relaxation rates measurable by the Gorter type experiments in zero constant magnetic field (Gorter RRs) are analytically investigated in magnetically concentrated paramagnets with the dominating exchange interaction. The consideration is restricted to the experiments, where the EPR linewidth is both anisotropic and linear over the temperature. It is suggested that under such conditions the EPR broadening is caused by the spin-lattice relaxation of the anisotropic interaction via the one-phonon mechanism. The analytical results are brought to the form suitable for the extraction of the Dzyaloshinsky-Moriya and the crystal field interaction constants from the experiment. It is shown that the EPR linewidth at the constant field direction along any crystal axis is equal to the half sum of the zero-field RRs for the two other crystal axes. The obtained results are successfully used for the interpretation of the EPR experimental results in the La0.9Sr0.1MnO3 and La0.875Sr0.125MnO3 single crystals in the Jahn-Teller strongly distorted phase in the definite temperature interval. The angular dependencies of the Gorter RRs and the EPR linewidth are presented graphically at the constant field continuous rotations in the three crystallographic planes in La0.9Sr0.1MnO3. © Kazan Federal University (KFU).

In the present paper, using the thin discontinuous Co films as examples we have investigated the influence of the shape of magnetic particles on the magneto-optical and optical properties of the nano-dispersive structures. Obtained results have confirmed the significant change of the components of the tensor of effective dielectric permittivity and subsequently of the magneto-optical and optical properties which was brought about by the change of the shape of magnetic particles. These calculations proved that if we take into account the shape of the particles, we will achieve a good agreement between the experimental results and the theoretical calculations. © 2016 IEEE.

In the present paper curried out a comparative analysis between the stroboscopic and phase-modulated methods of fluorescence analysis of optically solid media. It is shown that both methods have advantages and disadvantages, but the stroboscopic method is more sensitive. Parameters of fluorescence spectroscopy, like: radiation spectrum, life duration, quantum yield, fluorescence anisotropy - represent the sensitive functions of the processes, which depend of the life duration of excited condition. The molecules can participate in these processes which are in 10 nm distance from fluorofore at the moment of excitation. Therefore, the stroboscopic method has wide application in biology, medicine, material studies and nanotechnology, and of course, in ecology. © 2016 IEEE.

When the transfer of modern sciences to and the study of the Black Sea Region (BSR) began in the late 18. century, this area was not yet considered part of Europe. The proposed inter/multidisciplinary research and exchange projects title refers to that fact. Knowledge and science exchange between Europe and the BSR intensified in the course of the 19th and early 20th century and was interrupted when as result of WWI/WWII a significant part of the BSR was integrated into the Soviet Unions orbit. The BSR disappeared behind the Iron Curtain and the academic cultures of West and East drifted apart. The previous 25 years have witnessed strengthening ties between BSR countries and between the BSR and the rest of Europe as well as globalisation of knowledge and scientific exchange. The integration of the BSR into the European Research Area (ERA) is on the way but not yet completed. The proposed project provides excellent opportunities to critically reflect the sketched processes and to look into future. The suggested projects quality, credibility and novelty lies in its * attempt to systematically investigate knowledge and cultural exchanges between the BSR and Western Europe from the late 18th century to the present, * theoretical and methodological approaches with the potential to establish new pathways for future research and in its foregrounding of gender aspects. The suggested project establishes a network consisting of 12 research institutions from 12 BSR countries and Austria. It includes representatives of all the core disciplines of the humanities emerging around 1900. Innovative aspects of the proposed project consist of 1) drawing attention to an emerging region (BSR) consisting of countries previously considered as belonging to separate historical regions, 2) systematic investigation of knowledge and culture exchange within and beyond the region, 3) innovative theoretical framework, 4) inter/multidisciplinary methodology and 5) explicit gender perspectives.

In the present work we have shown the effciency of complex investigation of the ion implanted garnet surface region by magneto-optical and optical methods. We have investigated the optical and magneto-optical properties of the ion-implanted (YBiCaSm)3(FeGeSi)5O12 garnet films. It has shown that ion implantation influences significantly the magneto-optical properties of the garnet films and practically does not change its optical characteristics. We have also determined the spectral dependences of the component of the tensor of dielectric permittivity for the surface of ion implanted (YBiCaSm)3(FeGeSi)5O12 ferrite-garnet films before and after implantation process. These calculations let us evaluate the influence of implantation on an electronic energy structure of the surface layer for the sample.

The aim of research was monitoring of the main atmospheric air pollutants concentration on Adjara Autonomous Republic territory in order to determine their role in causing different diseases. The following atmospheric air pollutants have been determined in Batumi: dust, carbon monoxide, sulfur and nitrogen dioxide. The number of diseases registered in Adjara Autonomous Republic, which may be linked to the air pollution, has been studied. These are the following: chronic and nonspecific bronchitis, asthma and asthma status diseases, allergic rhinitis, trachea-, bronchi- and lung malignant tumor. In order to reduce the number of risk-factors significant attention should be paid to the proper functionality of the vehicles and systematic observations should continue on the chemical pollution of the air to make proper decisions to reduce the number of diseases.


The aim the research was to study the hormonal state of reproductive age women with tumors of body of uterus. The quantitative changes of sex steroid hormones: progesterone (P), estradiol (E), testosterone (T), gonadotropine -Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) were investigated. Distribution of ABO blood group antigens and Rh-Hr systems genetic variants in the blood of women living in Adjara Region was also studied. For study was used reproductive age women's blood with benign (fibromioma) and malignant (endometrial cancer) tumors of body of uterus (the middle age was 20-45 years). The determination of hormones was made by the enzymatic analysis method (ELAIZA). For the research of blood groups, were used the immunoserologic methods. The study have revealed that in blood of reproductive age women with benign and malignant tumors of body of uterus, level of estradiol was increased while levels of progesterone and testosterone were sharply reduced. Amount of Follicle-stimulating hormone and Luteinizing hormone were also increased. It's significant that, both hormones were sharply increased in case of cancer of body of uterus, in comparison with control group and benign tumor. According to distribution of ABO blood group phenotypes - O (I) phenotypic group of ABO system has its highest frequency in blood of women with cancer of body of uterus. Cancer of body of uterus is associated with O (I) phenotypic groups; benign tumor of body of uterus - with A(II) and AB(IV) phenotypic groups. Women with cc and EE genetic variants of Rh-Hr system have sensitivity to the development of benign and malignant tumors of body of uterus; women with ee genetic variant have lower sensitivity towards body of uterus cancer and sharply expressed sensitivity to uterus benign tumors. In women with malignant tumors of body of uterus the frequency of distribution of Rh-Hr system CC genetic variant was sharply reduced.

A relative lack of data for Eastern Europe and unknown epidemiology of childhood asthma in Batumi (Georgia) justified a study aimed at determining the prevalence of physician-diagnosed asthma and related respiratory conditions, a comparison of the prevalence of these conditions between urban and rural children, and identification of their environmental correlates.Subjects of the cross-sectional population-based study were 3238 urban and 2081 rural children aged 5-17years whose respiratory status was assessed using the ISAAC questionnaire.The overall prevalence of asthma was larger in rural children than in urban children (2.8% vs. 1.8%, respectively; p = 0.01). Spastic bronchitis occurred with similar frequency in urban (7.8%) and rural children (6.5%). Compared with urban children, rural subjects had dry cough at night (13.1 vs 8.2%, p < 0.001) and attacks of dyspnea (4.7 vs 2.4%, p < 0.001) more often. The prevalence of other symptoms did not differ significantly between urban and rural subjects. Results of multivariate analyses showed that both asthma and spastic bronchitis were associated (p < 0.05) with parental history of asthma, dampness in the house, and poor financial standing of the family. In addition, asthma was related to coal/wood-based heating whereas spastic bronchitis was associated with passive smoking and lower parental education.The findings show a low prevalence of ever-diagnosed asthma in the examined population. Nosological tradition and similar correlates of asthma and spastic bronchitis suggest that some cases of asthma might be included in the diagnostic category of spastic bronchitis.

Aim - to define the parameters of physical development of children in orphanages. 72 children (45 boys, 27 girls) without chronic debilitating diseases and condition aged from 1 to 6 years from Tbilisi and Makhinjauri orphanages (Georgia) were assessed. Height and weight of all subjects were measured and BMI, height SDS (standard deviation score) and weight SDS were calculated. Data were compared to the normal values (national data). The retardation of the physical development were seen along almost all findings. The significant differences regarding age and gender were not revealed. The most expressed tendency to delay was expressed in the height of boys, particularly aged 3-5 years. Our data confirm that institution upbringing has a negative impact on the growth of children of 1-6 years of age. In children aged from 1 to 6 years who are healthy but live in orphanages there is a marked tendency to lag behind in physical development, mainly in height. The above-mentioned confirms the opinion about negative impact of upbringing in orphanages on the physical development of children.
