Complex radiation-thermal history of Kaidun meteorite on data of track study of silicate minerals

The results of track study of approximately 80 individual silicate mineral crystals (ol, px, plag) picked out from Kaidun meteorite are presented. A wide range of observed rho(sub VH) value distributions indicate the complex irradiation history of Kaidun minerals. In one anortite crystal having two track groups with different parameters the pre-accretion irradiation traces were observed in all probability

Modernization of Primary Healthcare: Efficiency of Social Policy in the Post-Soviet State

The national security depends on the health of the population, which, in its turn, depends on the healthcare system. After the collapse of the Soviet Union, Russia focused on the primary healthcare. The goals, tools, and results of the reforms that have taken place in the last three decades are usually considered from the point of view of law, economic feasibility, or organizational effectiveness. The author applied the historical and political approach to these reforms, thus evaluating their ability to preserve and increase human health. Fertility, morbidity, and mortality usually serve as national health criteria. The research relied on regulatory legal acts, speeches of senior government officials, official statistics, and sociological surveys. Demographic problems and budget deficits proved to be the main reasons behind the post-Soviet reforms, which transferred some material obligations from the federal to the local level and expended the scope of commercial medicine. Part of the financial burden moved from expensive specialized hospitals (secondary healthcare) to cheaper polyclinic and preventive medicine (primary healthcare). Federal budget expenditures decreased as patient capacity and the number of medical organizations went down and the productivity of primary healthcare went up. However, the national mortality and morbidity kept growing. The current diagnostic preventive healthcare model concentrates on primary healthcare: it reduces financial expenditures but fails to solve the demographic problems

Determination of Total Antioxidant Content in Various Drinks by Amperometry

In the present work the total content of phenolic antioxidants in juice of some fruit and vegetables, in wines, water extracts of tea and herb were measured by amperometry. Efficiency of the method allowed determining the total antioxidant content in their binary and multimixes, including processes of frosting-defrosting and juice diluting as well. The deviation of experimentally received values of the total antioxidant content in some drink mixes from the values calculated proceeding from the additivity principle of the antioxidant content in separate drinks has been revealed

Stimulating of entrepreneurs’ innovative activity in the Republic of Bashkortostan

The article views some aspects of promoting innovative activity in the Republic of Bashkortostan. The measures stimulating innovative activity have been grouped into blocks.1. Creating favorable conditions for innovative activity. 2. Increasing the population’s innovative activity. 3. Development of the system of scientific and production cooperation and innovation commercialization. 4. Investment support of innovative projects. 5. Development of innovative infrastructure. 6. Development of innovative small businesses. 7. Information provision of innovative activity. The main directions of implementing the above-mentioned conditions are: - lawmaking activity in the Republic, taking into consideration the federal legislation, international standards and traditions; - financial and tax inducement of scientific-technical and innovative activity; - international technological integration; - private-state partnership in the sphere of innovative activity. Recommendations are suggested, relating to the innovative policy activation for more efficient fulfillment of the key functions of the Republic’s scientific and research sector. The authors conclude that the Republic has all necessary preconditions for small entrepreneurship functioning: the natural conditions favorable for many kinds of economic activity, the forming local market infrastructure for small business servicing, and the availability of large enterprises and centers of economic activity.Keywords: entrepreneur, entrepreneurship, innovation, innovative activity, region, infrastructure, investments, stimulation, monitoring

Dietary fiber is a reliable and apparent element of treatment for patients with type 2 diabetes mellitus and cardiovascular diseases: an easy solution to a complicated problem

Cardiovascular diseases are a frequent comorbid condition in patients with type 2 diabetes mellitus (t2DM). This problem tends to remain acute because of the progression of t2DM, which increases the chances of cardiovascular events. Medicine today has a range of innovative hypoglycemic drugs, which proved their safety and effectiveness towards diseases of cardiovascular system. However, high cardiovascular mortality demonstrates that the medication is not enough effective. Partly lack of success may be explained by not enough work with unmodified risk factors, such as physical activity, smoking and excessive and wrong nutrition. Studies about dietary fiber (DF) let us discuss their including in the dietary plan of patients with t2DM and cardiovascular diseases. One of the promising DF types is Cyamopsis tetragonoloba extract. It showed its effectiveness concerning carbohydrate metabolism and lipid profile, improving, metabolic features of t2DM patients and lowering the risks of cardiovascular events. What is more, the advantage of Cyamopsis tetragonoloba extract is easy to use and has no side effects

ФИЗИКО-ХИМИЧЕСКИЕ ЗАКОНОМЕРНОСТИ ПРОЦЕССА ЭЛЕКТРОВОССТАНОВЛЕНИЯ КИСЛОРОДА В ПРИСУТСТВИИ ПРИРОДНЫХ АНТИОКСИДАНТОВ

The effect of individual antioxidants on physico-chemical parameters of ORR was studied under conditions of liner semi-infinite diffusion. Rate constants for coupled homogeneous reduction of active oxygen by the range to flavonoids were calculated under the optimal linear sweep rate.Possibility of determination of the parameters of reduction of active oxygen process (chemical and electrochemical rate constant, reversibility of process) in addition of individual antioxidants was showed by the computer simulation. Identification of substances with antioxidant properties was illustrated by changing of reduction current of active oxygen.Keywords: oxygen reduction reaction, ORR, antioxidant, flavonoids, rate constant, voltammetry(Russian)DOI: http://dx.doi.org/10.15826/analitika.2013.17.4.007A.N.
