Electrochemical properties and catalytic activity in the ethylene polymerization processes of nickel complexes with 2,2′-bipyridine in the presence of ortho-phosphinophenol derivatives

© 2015, Pleiades Publishing, Ltd. Electrochemical properties of the [NiBr2(bpy)2] complex, where bpy = 2,2′-bipyridyl, have been studied in the presence of derivatives of ortho-phosphine phenol: 2-diphenyl phosphanyl-4-methyl phenol CH3C6H3(PPh2)OH (1), 2-diphenyl phosphanyl-4-methylphenyldiphenyl phosphinate CH3C6H3(PPh2)OP(O)Ph2 (2), and 2-diphenylphosphoryl-4-methyl phenol CH3C6H3(P(O)Ph2)OH (3). It is found that interaction of products of electrochemical reduction of complex [NiBr2(bpy)2] with 1 and 2 results in formation of active catalysts of the process of homogeneous oligomerization/polymerization of ethylene

АНТЕГРАДНАЯ ПАПИЛЛОТОМИЯ С ИСПОЛЬЗОВАНИЕМ YAG:HO ЛАЗЕРА ПРИ СТЕНОЗЕ БОЛЬШОГО СОСОЧКА ДВЕНАДЦАТИПЕРСТНОЙ КИШКИ

The purpose of our study was to develop and implement a new invasive method of papillotomy – an antegrade dissection of the major duodenal papilla using high-energy holmium (YAG:Ho) laser. Results of antegrade laser papillotomy in 35 patients are presented. All surgical procedures were laparoscopic, no indications for conversion were found. The use of high-energy holmium laser helps perform an adequate papillotomy with minimal damage to the surrounding tissues. Studies have shown that antegrade laser papillotomy is feasible in the presence of parapillary diverticula, severe deformity of the duodenum, and also when retrograde interventions are extremely difficult or impracticable. The high efficiency of the applied technique (in all cases the stenosis of the major duodenal papilla has been successfully eliminated) and the absence of complications and deaths is shown. Based on the analysis of the study results, a therapeutic algorithm for managing patients with stenosis of the major duodenal papilla is proposed.Разработан и внедрен новый способ папиллотомии путем антеградного рассечения большого сосочка двенадцатиперстной кишки высокоэнергетическим излучением гольмиевого (YAG:Ho) лазера. Представлены результаты выполнения антеградной лазерной папиллотомии у 35 пациентов. Все оперативные вмешательства выполнены лапароскопически, показаний для конверсии не было. Применение высокоэнергетического гольмиевого лазерного излучения позволило выполнить адекватную папиллотомию при минимальном риске повреждения окружающих тканей. Исследования показали, что антеградная лазерная папиллотомия выполнима при наличии парапиллярных дивертикулов, выраженной деформации двенадцатиперстной кишки, а также когда ретроградные вмешательства крайне затруднительны или невыполнимы. Показана высокая эффективность применяемой методики (во всех случаях успешно устранен стеноз большого дуоденального сосочка) и отсутствие осложнений и летальных исходов. На основе анализа результатов исследования предложен лечебный алгоритм ведения пациентов со стенозом большого сосочка двенадцатиперстной кишки

Russian population health-related quality of life indicators calculated using the EQ-5D-3L questionnaire

Objectives. The paper aims was forming the first health-related quality of life population indicators using EQ-5D–3L survey that represents the Russian population by gender and age, as well as by the attained level of education. Material and methods. For compiling population indicators, we use the EQ-5D-3L questionnaire. The study was conducted on the adult Russian population aged 18 to 75 years. A representative sample was 12616 respondents. Results. 59.3 % of the sample is in good health (profile 11111). The proportion of respondents reporting any health problems increases with age. The average score on a 100-point visual analogue scale is 72.4 (standard deviation 18,1; 95 per cent confidence interval from 72,1 to 72,7). Men, on average, tend to assess their health higher than women. However there are no statistically significant differences in health scores among educational groups, taking into account gender and age data. Conclusions. Comparison of health-related quality of life estimations with normative population data allows us to track differences in health between population groups, as well as to analyze the health status and progress in treating patients. The Russian health-related quality indicators from EQ-5D-3L survey are similar to the Hungary population indices, as well as to many European countries, the USA, and Argentina for age cohorts under 45 years of age. For the cohorts of respondents older than 45 years, Russian estimations are much lower than in other countries. This evidence confirms that borrowing scales from other countries for converting EQ-5D-3L values into a preference EQ-5D-3L index is not acceptable for Russian patients, especially for the elderly

Government Support Policy of the russian Enterprises During the 2008—2009 Crisis: Criteria of Treating the Companies as “Strategic”

Support of individual enterprises was an important part of anti-crisis policy of Russian government during 2008—2009. The officially declared goal of this support was maintaining sustainability of “systemically important”, or strategic enterprises. Using regression analysis, the author seeks to determine the extent to which inclusion in the The List of strategic organizations approved by the Government Commission on sustainable development of the Russian economy in December 2008 was defined by the social significance of the company or by its affiliation with one of the 16 largest Russian business groups.</jats:p

Financial literacy training programs and financial behaviour: Why people do not become “financially literate”?

The paper takes a critical view on the prevalent approaches to developing financial literacy programs. It has been shown that meta-analytical and review studies indicate low efficiency of financial literacy improvement programs: their effect on financial behavior is either statistically insignificant or statistically significant, but practically negligible. Among potential reasons of financial literacy programs low efficiency the role of behavioral factors in financial decision making and the impossibility of determining “financially literate” behavior from the perspective of an outside observer are considered. It is concluded that the currently dominant criteria for assessing financially competent behavior can be characterized either as procedural, within which not the consequences of financial decisions are considered, but how consciously they are taken, or as normative, within which the government differentiates the consumers attitudes into wrong and right. Both groups of criteria are based on a non-economic understanding of rationality.</jats:p
