Acupuncture as a Complimentary and Alternative Method of Managing Polycystic Ovarian Syndrome

The purpose of this paper is to evaluate the efficacy of acupuncture therapy in the treatment of polycystic ovarian syndrome (PCOS) by reviewing clinical trials and randomized and observational studies. The mechanism of acupuncture treatment in PCOS and implications for future use are aIso reviewed. A comprehensive literature search was conducted through the databases Medline, PubMed, Allied and Complimentary Medicine (AMED), and The National Center for Complimentary and Alternative Medicine (NCCAM) to identify all relevant articles. Available acupuncture studies on human subjects with PCOS from 1976 to 2009 were reviewed. Even though more research is needed to discover the true effect of acupuncture, studies implyincidence of side effects make it an excellent alternative treatment option for women with PCOS

TAX STIMULATION OF INVESTMENT ACTIVITY IN RUSSIA

The article considers the problem of tax incentives for investment activity in the Russian Federation in the current economic conditions. It is shown that in crisis economic conditions, with a financial resources deficit, tax incentives are a key mechanism ensuring the implementation of investment programs of natural monopolies and import substitution projects. The objectives of the tax policy are defined and recommendations are formulated to improve a number of taxes in order to stimulate investment in the Russian economy

Evaluation of the Comparative Effectiveness of Fiscal Measures and Supply Chain Strategy at Stimulating Oil Production from 2010 to 2016 Carried Out with the ï¥-KAM Mathematical Model

The article evaluates the effectiveness of measures of supply chain management and national fiscal policies aimed at stimulating oil production in several countries (the USA, Canada, Brazil, Norway and Russia). Calculations were carried out with the ï¥-KAM mathematical model using the data for the period from 2010 to 2016. The model includes the following: the input indicators are budget transfers and tax benefits for oil producers, and the output indicators are the average annual volumes of oil production. Regarding the price efficiency of fiscal policy aimed at stimulating oil production in 2010–2016, Russia showed the lowest result. At the same time, Russia demonstrated the highest efficiency of using budget transfers to stimulate oil production, and Canada achieved the greatest efficiency in applying tax measures

Impact of fiscal, monetary and structural economic policies on the growth rates of leading economies : 2000-2016

The article analyzes the impact of measures and instruments of fiscal, monetary, and structural economic policies on the growth rates of the economies of many countries around the world from 2000 to 2016, considering the provisions of the structural theory of development. The dynamics of the following indicators of national economies is analyzed: GDP growth rate; total tax rate, central government debt; domestic credit to the private sector; consumer price inflation; high-tech exports as a share of country industrial exports and in value terms. It was revealed that for balanced long-term growth of the economy, it is necessary that the structure of the national economy should include industries whose exported goods are characterized by high elasticity of demand, and goods imported by low elasticity of demand. Selective tools of state stimulating economic policy should be aimed at industries that can generate innovations and promote the dissemination of the results of technological progress.peer-reviewe

Time accurate numerical cavitation erosion prediction of multiphase flow through a venturi

Cavitation erosion affects the efficient operation of the vessel’s propeller, leading to increased costs of operation and maintenance. Traditionally, erosion is predicted using dedicated cavitation tests with utilization of soft paint application or materials as erosive sensors. However, even with materials that are most susceptible to erosion, such tests constitute significant amount of time. It is well-known that cavitation erosion occurs with the impact of high velocity liquid jets generated by the imploding bubbles, also called water hammer effect, and induced shock waves over time. However, it is both not a viable approach to simulate the complete duration of an experiment using numerical methods and extremely expensive in terms of computational time. Therefore, it is a common simplification to assume cavitation events to be repetitive for numerical simulations and based on this assumption there has been a plethora of studies utilizing the numerical simulations for cavitation erosion prediction. Whilst these simulations utilize instantaneous erosive power indicators for cavitation erosion estimation, an approach that takes into account of the summation/accumulation of the erosive intensity over time for precise erosion threshold determination is non-existent. Within this framework this study presents a time accurate numerical cavitation erosion prediction based on the intriguing experimental study conducted by Petkovšek & Dular (2013) that achieved visual cavitation erosion within 1.5 seconds. In addition to the well-known erosive indicators such as Erosive Power Function (Eskilsson & Bensow, 2015), Gray Level Method (Dular et al., 2006) and Intensity Function Method (van Terwisga et al., 2009), in house functions developed by Lloyds Register (LR) Technical Investigation Department (TID) (Ponkratov, 2015; Ponkratov & Caldas, 2015) are used to compare against the experimental results. Comparisons both aided the determination of a time accurate threshold and utilized as an evaluation case for each erosive indicator

Graphical Analysis of the Growth Rate of National Economies by Considering the Supply Chain Strategy in 25 Countries over the Period From 2000 to 2016

The article presents the graphical analysis of economic indicators for 25 countries: GDP growth rate (%) and GDP per person employed (thousand US dollars) for the period from 1990 to 2016 by considering the supply chain strategy (SCS) and transparency. The authors carried out the decomposition of economic growth rates of selected countries according to the following factors: 1) extensive factors – the growth rate of the capital stock and the size of labor force; 2) intensive factors – RD expenditures; 3) the dynamics of foreign direct investment in the country 4) supply chain strategy. Over the past 16 years, only a few countries from the sample have shown growth of the national economy higher than the growth rates of the world economy. These are China, Turkmenistan, India, Malaysia, and Singapore (their economies grew at a rate of more than 5% per year). The most dynamic renewal of fixed assets can be observed in China, the United States and Japan. At the same time, over the past 10 years China has demonstrated an active investment policy, increasing the investment in fixed assets almost five times. China and India were countries that most actively used the size of labor force as a factor of extensive growth. Korea, Japan, Germany, USA, China and Singapore demonstrated the most dynamic growth in RD expenditures. Despite the non-monotonous dynamics of foreign direct investment in these countries, over the entire period of observation from 1990 to 2017, the United States has been the most attractive country for foreign direct investment. At the same time, the most significant growth in foreign direct investment was recorded in China and, recently, in the United Kingdom

PROBLEMS OF THE FINANCIAL RESULT ANALYSIS OF THE COMPANIES CONSOLIDATED GROUP IN THE INVESTMENT DEVELOPMENT CONDITIONS

The analysis of the financial result of the companies consolidated group has considered. The interpretation of the «financial result» concept applied to the group of financial and organizational related enterprises has given. It has shown, that the main analysis problems are the relationships opacity within the group as well as the specificity of the individual companies accountability and their subsequent consolidation into the group's accountability. An example of the financial result analysis of the companies group operating in the conditions of the investment development program has given
