    Hybridization and spin-orbit coupling effects in quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12

    Full text link
    We study electronic and magnetic properties of the quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12 with a distinct orthogonal connectivity of CuO4 plaquettes. An effective low-energy model taking into account spin-orbit coupling was constructed by means of first-principles calculations. On this basis a complete microscopic magnetic model of Ba3Cu3Sc4O12, including symmetric and antisymmetric anisotropic exchange interactions, is derived. The anisotropic exchanges are obtained from a distinct first-principles numerical scheme combining, on one hand, the local density approximation taking into account spin-orbit coupling, and, on the other hand, projection procedure along with the microscopic theory by Toru Moriya. The resulting tensors of the symmetric anisotropy favor collinear magnetic order along the structural chains with the leading ferromagnetic coupling J1 = -9.88 meV. The interchain interactions J8 = 0.21 meV and J5 = 0.093 meV are antiferromagnetic. Quantum Monte Carlo simulations demonstrated that the proposed model reproduces the experimental Neel temperature, magnetization and magnetic susceptibility data. The modeling of neutron diffraction data reveals an important role of the covalent Cu-O bonding in Ba3Cu3Sc4O12.Comment: 11 pages, 12 figure

    Unmarked Case of Amiodarone-Induced Thyrotoxicosis

    Patient I. had marked complaints, which were typical for thyrotoxicosis syndrome at September 2009. As a result based on depressed level of TSH and increased value of free T4 Graves` disease have been diagnosed, and Thiamazole have been prescribed, but patient wasn`t relieved. In Rostov-on-Don Endocrinology Centr because of there had been no effect from treatment, the diagnosis was call into question. Differential diagnostics thyrotoxicosis syndrome had been led and destructive tryroiditis have been revealed. Also it was found out that patient was taking Cordarone during 1,5 years, which contains a high concentration of iodine and results in development of several thyroid gland`s pathology. Thus, instead of radioiodine therapy patient needs to take glucocorticoids

    ULTRASONOGRAPHY OF SUBCUTANEOUS FAT AS A METHOD OF INSULIN INDUCED LIPOHYPERTROPHY DIAGNOSTICS IN DIABETIC PATIENTS

    Get PDF
    Purpose: To evaluate the frequency of insulin induced lipohypertrophy (LH) in diabetic patients revealed by observation and palpation techniques, as well as ultrasonography of subcutaneous fat.Materials and methods: This study was done on 192 diabetic patients (mean duration of disease was 10 years) who had been under the treatment with insulin a mean 8 years. Observation and palpation techniques, as well as ultrasonography of subcutaneous fat were used in assessing LH in these diabetics.Results: On the basis of palpation LH were revealed in 27,7% patients. Further ultrasonography of injection sites was performed to all patients. LH were revealed in 83,2% patients, including those subjects with palpatory changes. Pathologic areas of subcutaneous fat the most often were occurred in paraumbilical regions – 61% patients.Summary: Problem of LH has been modified. As a result, traditional methods of LH diagnostics have become not an informative. This question is needed an additional investigation

    Effect of natural surface-active substances on the rheological properties of emulsions

    Get PDF
    The effect of natural surface-active substances on the formation of emulsions in oils with different content of resin-asphaltene components (RAC) and paraffin hydrocarbons (PHC) (RAC/PHC from 0.7 to 95) is studied. The influence of oil composition and content of aqueous phase on microstructure, rheological properties, and activation energy of viscous flow of water-oil emulsions is shown. For oils with the ratio RAC/PHC < 1, the increase in water cut results in an increase in viscosity, activation energy of viscous flow, and pour point

    Prompt neutrino fluxes from atmospheric charm

    Full text link
    We calculate the prompt neutrino flux from atmospheric charm production by cosmic rays, using the dipole picture in a perturbative QCD framework, which incorporates the parton saturation effects present at high energies. We compare our results with the next-to-leading order perturbative QCD result and find that saturation effects are large for neutrino energies above 10^6 GeV, leading to a substantial suppression of the prompt neutrino flux. We comment on the range of prompt neutrino fluxes due to theoretical uncertainties.Comment: 13 pages with 11 figures; expanded discussion, added references, version to be published in Phys. Rev.

    BROWN ADIPOSE TISSUE IN ADULTS: CONSENSUS POINTS AND GUIDELINES FOR FUTURE EXPERIMENTS

    Get PDF
    As part of a current worldwide effort to understand  the physiology of human BAT (hBAT) and whether its thermogenic activity can be manipulated to treat obesity, the workshop ‘‘Exploring the Roles of Brown Fat in Humans’’ was convened at the National Institutes of Health on February 25–26, 2014. Presentations and discussion indicated that hBAT and its physiological roles are complex, and research is needed to understand  the health impact of hBAT beyond thermogenesis and body weight regulation, and to define its interactions with core physiological processes like glucose homeostasis, cachexia, physical activity, bone structure, sleep, circadian rhythms. Consensus points and guidelines for future experiments have been summarized in the article of Aaron M. Cypess, Carol R. HaftMaren, R. Laughlin, Houchun H. Hu. Brown Fat in Humans: Consensus Points and Experimental Guidelines (Cell Metabolism. 2014 Sep 2;20(3):408-15. DOI: 10.1016/j.cmet.2014.07.025), which more extensive referat is presented by authors of this paper

    Mechanisms of fertility disorders in obese women

    Get PDF
    Obesity is a common problem among women of reproductive age. Overweight is known to negatively affect a woman’s fertility. So, women of reproductive age who are obese may experience menstrual irregularities, endometrial pathology and, ultimately, infertility. The pathogenetic mechanisms of reproductive dysfunction in obesity remain actively studied issues. It was established that leptin synthesized by adipose tissue inhibits granulosis, cell steroidogenesis and interferes with the ovulation process, which can directly affect reproductive function. Insulin resistance and compensatory hyperinsulinemia, which accompany obesity in women, can contribute to menstrual irregularities, ovulation and, ultimately, fertility. Obesity is also characterized by a state of «relative functional hyperandrogenism», which can affect ovarian function, contributing to the development of infertility. Moreover, obesity is characterized by a state of hyposomatotropinism, which can affect fertility, through changes in ovarian and endometrial function. Weight loss is most likely able to restore fertility in most cases, but there are no practical guidelines that would help the clinician choose the best method to reduce body weight from increased physical activity, dietary restrictions, drug therapy and bariatric surgery

    Institutional criteria for the assessment of intellectual products` potential realization in the venture financing system

    The objective of the research is to elaborate institutional criteria for the assessment of intellectual products` potential realization in the venture financing system which are not presented in the existing works on venture investments. Research methodology is based on synthesis of institutional and new institutional economics theory, theories of innovations, uncertainty and risk, management of innovations. Essential characteristics of venture financing are structured in the paper, its treatment as an economic category is suggested. A number of common institutional criteria for the assessment of intellectual products` potential feasibility in the system of venture financing are outlined and grounded. The structure of institutional field of venture financing (by the example of Sverdlovsk region) is elaborated with consideration of projected development and coevolution of formal and informal institutions as a favorable environment for drawing into economic turnover and commercialization of technological developments and projects. Analytical investigation of structural elements for creation of institutional field of venture financing in Sverdlovsk region is performed, a range of common and specific problems, contradictions and recommendations are outlined. The paper introduces institutional criteria for the assessment of intellectual products` potential feasibility
