    Full Text Available The paper deals with the theory and practice of social audit of the municipal system of general education. The authors have developed a conceptual model of social audit to accurately identify both the short- and long-term development prospects of the given system. The paper describes the social audit procedures in Berezovsky municipal district of Sverdlovsk region including four stages: the content analysis of municipal documents concerning the development strategy of the general education system, diagnosis of the current conditions and problems, effectiveness evaluation of the municipal system of general education, and practical  recommendations for improving the education quality. The above mentioned audit demonstrates that the indices of education development are unsystematically tracked, obstructing therefore the adjustment process. To solve the given problems the following measures are recommended: personnel policy development, creating the regional managerial reserve and organizing management workshops, informing the teachers about the modern educational tools, and updating the municipal program of the «Educational System Development of Berezovsky Municipal District for 20011–20015». However, the above suggestions target only the current problems disregarding the challenges of tomorrow which require the advancing strategy. In authors’ opinion, the main emphasis should be re-placed on the quality improvement of the municipal educational services instead of the infrastructure reinforcement.

    The outstanding theoretical physicist Arkady Benediktovich Migdal was one of the pioneers of theoretical nuclear physics in the Soviet Union, the founder of a major scientific school, a man of diverse gifts and irresistible personal charm. A. B. Migdal was born on March 11, 1911, in Lida (Belarus). In the 1920s his family moved to Leningrad. Migdal produced his first scientific work at age 17. He then enrolled at the physics department of the Leningrad State University (LSU), but studied there only a short while: arrested, he spent over two months under investigation, then was released (releases were still granted sometimes then). From 1931 to 1936, while working at the factory "Electrical Appliance," he produced several scientific works. At this time he managed to recover a place at the LSU extension division. After graduation in 1936 A. B. Migdal enrolled in graduate school at the Leningrad Physical-Technical Institute, where he formed his research interests and his own research style. His thesis adviser was M. P. Bronshtein. [Note: See footnote, p. 171.] Despite the briefness of this contact with Bronshtein - in 1937 Matvei Petrovich was arrested and executed - this bright, talented and deep person played a major role in Migdal's scientific development...

    The Clusters of Orthologous Groups (COGs) of proteins systematize evolutionary related proteins into specific groups with similar functions. However, the available databases do not provide means to assess the extent of similarity between the COGs. We intended to provide a method for identification and visualization of evolutionary relationships between the COGs, as well as a respective web server. Here we introduce the COGcollator, a web tool for identification of evolutionarily related COGs and their further analysis. We demonstrate the utility of this tool by identifying the COGs that contain distant homologs of (i) the catalytic subunit of bacterial rotary membrane ATP synthases and (ii) the DNA/RNA helicases of the superfamily 1. This article was reviewed by Drs. Igor N. Berezovsky, Igor Zhulin and Yuri Wolf.

    Full Text Available The work is devoted to study of features of the status of smoking in patients with the chronic obstructive pulmonary disease (COPD. Degree of nicotine addiction, types of smoking behavior in various age groups of patients are determined. The interrelation at sick HOBL between motivation to refusal of smoking and the attitude towards health is analyzed. The directions of psychotherapeutic impacts for increase in efficiency of the techniques directed to refusal of smoking are offered.Objective  – to study the motivation to quit smoking and attitudes towards health in patients with COPD. Materials  and  methods. A questionnaire by D. Horney for determining the type of smoking behavior; Fagerstrem test for the determination of nicotine dependence; the questionnaire for determining the motivation to refuse to smoke; the questionnaire of N.E. Vodopyanova «Assessment of the level of satisfaction with the quality of life» (2005 and the methodology «Attitude to health» by R. A. Berezovsky.Results.  The average age for the entire sample of respondents was 65.3±7.6 years, the length of smoking in smokers was 33.5±14.3 years. The predominant type of smoking behavior in the survey sample was «Support». In patients with high motivation, the assessment of the level of satisfaction with the overall «quality of life index» (ICI was 26 points. In patients with low motivation to quit smoking, the mean value (ICR was 21.Conclusion. Patients with high motivation to quit smoking were older than patients with low motivation. A group of patients with COPD with high motivation to quit smoking was characterized mainly by low or medium degree of nicotine dependence; the dominant type of smoking behavior of them was «Support.» On the contrary, in the group of patients with low motivation, physical dependence on nicotine prevailed; the «thirst» was the dominant type of smoking behavior.

    Soviet and Russian theoretical physicist Lev Borisovich Okun passed away on 23 November, 2015, after a long illness.     Lev Okun was born in 1929, in western Russia and graduated from the Moscow Institute for Physics and Engineering in the early 1950s under the supervision of Arkady Migdal. Lev Okun came to the Institute of Theoretical and Experimental Physics (ITEP) in 1954 as a graduate student of Isaac Pomeranchuk, the head of the ITEP Theory Department. In 1956 he was instrumental in the proof of the Okun–Pomeranchuk theorem, establishing the asymptotic equality of cross sections of certain scattering processes. A number of Okun’s pioneering works were devoted to weak interactions of elementary particles. In particular, he was among the first to explain the special features of CP preserving neutral kaon decays, and his results on the false vacuum decay and domain walls in cosmology are of paramount importance....

    2015-05-01

    We report a case of a 14-year-old female with primary adenocarcinoma of the transverse colon. She was hospitalized after presenting with abdominal pain and signs of intestinal obstruction. There was no health antecedent or family history of neoplasia. Physical examination revealed a distended abdomen. Tenderness was elicited to palpation of the right lower quadrant. Magnetic resonance imaging of the abdomen revealed obstructive signs, with a constricting lesion in the mid-transverse colon of probable neoplastic nature. Laparoscopic segmental resection of the colon was followed by standard right hemicolectomy. A circumferential mid-transverse tumor was diagnosed as primary colorectal carcinoma (CRC) of signet-ring cell type, AJCC stage IIIC, Dukes' C stage. On the basis of immunohistochemistry and clinical data, hereditary nonpolyposis and hamartomatous colorectal cancer syndromes were excluded. Involvement of either the p53, BRAF, or K-RAS genes was ruled out by immunohistochemistry profiling and genetic testing. The neoplasm was categorized as sporadic. The possibility of activation of the Wnt signaling pathway was suspected, because of a defective turnover of the β-catenin protein. Postoperatively, the patient was treated with both systemic and intra-abdominal adjuvant chemotherapy, including oxaliplatin. Between 18 and 24 months after diagnosis, intra-abdominal tumor recurrences were detected. The patient underwent bilateral oophorectomies for Krukenberg tumors and received salvage chemotherapy. Recently, additional recurrent metastatic retroperitoneal disease caused hydronephrosis. The retroperitoneal mass was debulked and a ureteric stent was placed. At the time of this writing, 43 months after diagnosis, the patient is receiving FOLFOX chemotherapy combined with panitumumab. CRC of childhood is exceedingly rare, generally develops in the setting of unrecognized genetic predisposing factors to cancer, presents with advanced disease, is high grade, and tends to have dismal prognosis.

  14. Towards a complete Fermi surface in underdoped high Tc superconductors

    Science.gov (United States)

    Harrison, Neil

    The discovery of magnetic quantum oscillations in underdoped high Tc superconductors raised many questions, and initiated a quest to understand the origin of the Fermi surface the like of which had not been seen since the very first discovery of quantum oscillations in elemental bismuth. While studies of the Fermi surface of materials are today mostly assisted by computer codes for calculating the electronic band structure, this was not the case in the underdoped high Tc materials. The Fermi surface was shown to reconstructed into small pockets, yet there was no hint of a viable order parameter. Crucial clues to understanding the origin of the Fermi surface were provided by the small value of the observed Fermi surface cross-section, the negative Hall coefficient and the small electronic heat capacity at high magnetic fields. We also know that the magnetic fields were likely to be too weak to destroy the pseudogap and that vortex pinning effects could be seen to persist to high magnetic fields at low temperatures. I will show that the Fermi surface that appears to fit best with the experimental observations is a small electron pocket formed by connecting the nodal `Fermi arcs' seen in photoemission experiments, corresponding to a density-wave state with two different orthogonal ordering vectors. The existence of such order has subsequently been detected by x-ray scattering experiments, thereby strengthening the case for charge ordering being responsible for reconstructing the Fermi surface. I will discuss new efforts to understand the relationship between the charge ordering and the pseudogap state, discussing the fate of the quasiparticles in the antinodal region and the dimensionality of the Fermi surface.

    2011-06-01

    we have assembled a representative set of papers written by experts with diverse scientific backgrounds, each offering a unique viewpoint on using computational and physics methods to study biological systems at different levels of organization. We start with studies that aim to decipher the mechanisms of molecular recognition using biophysics methods and then expand our scale, concluding the issue with studies of interaction networks at cellular and population levels. Biomolecules interact with each other in a highly specific manner and selectively recognize their partners among hundreds of thousands of other molecules. As the paper by Zhang et al points out, this recognition process should be fast and guided by long-range electrostatic forces that select and bring the interacting partners together. The authors show that the increase of salt concentration leads to destabilization of protein complexes, suggesting an optimization of the charge-charge interactions across the protein binding interfaces. The following paper by Berezovsky further explores the balance of different interactions in protein complexes and uses physical concepts to explain the entire spectrum of protein structural classes, from intrinsically disordered to hyperthermostable proteins. The author describes highly unstructured viral proteins at one end of the spectrum and discusses the balance of stabilizing interactions in protein complexes from thermophilic organisms at the other. Recently accumulated evidence has indicated that native proteins do not necessarily require a unique structure to be biologically active, and in some cases structural disorder or intrinsic flexibility can be a prerequisite for their function. From the physical point of view, these disordered/flexible proteins exist in dynamic equilibrium between different conformational states, some of which could be selected upon binding to another partner. Such a property allows disordered proteins to achieve specific binding and at
