Eurasian Economic Union: Asymmetries of Growth Factors

The aim of the study is to assess the asymmetry of influence of factors of economic growth of national economies, which are included in the integration. Unlike previous research, the scientific significance of the obtained results consists in the use of a new method of study – external demand as a factor of economic growth, disaggregated into two components. The first is net exports mutual trade in goods within integration associations. The second is net exports of foreign trade in goods outside the integration. By use of these methods we have evaluated the contribution of these factors on economic growth of the Customs Union and the Common Economic Space (CU/CES), as well as Kazakhstan, Russia and Belarus. In the conducted analysis of scientific research was based on the fact that the economies of the member (CU/CES) are very different in scale, economic potential and volume of foreign trade. Based on this research we conclude: integration is developing successfully and efficiently only with the rise of the national economies of the member countries; to enhance economic growth and competitiveness of the countries of the Eurasian integration it is necessary to increase the volume of mutual trade of member countries of this integration

Optical-domain Compensation for Coupling between Optical Fiber Conjugate Vortex Modes

We demonstrate for the first time optical-domain compensation for coupling between conjugate vortex modes in optical fibers. We introduce a novel method for reconstructing the complex propagation matrix of the optical fiber with straightforward implementation

Complex processing of lipids from liver of the gonatid squid <i>Berryteuthis magister </i>

Berryteuthis magister is one of the most common commercial species in the North-West Pacific, but its liver never was utilized before, though it was a rich source of the lipids with simple ether links, 1- О -alkyl-glycerol ethers (АGE), and ω3 polyunsaturated fatty acids (ω3 PUFA). Technology for complex processing of lipids from its liver is developed and presented in details. These forms of lipids are distinguished by a wide range of biologic activity: AGE are effective immunomodulators which enhance hemopoiesis, relieve lesions and lower risk of secondary lesions under radio-therapy and can be used for treatment of some malignant tumors (glioma, prostate cancer, lung carcinoma, etc.); ω3 PUFA could be used for prophylactic of cardiovascular diseases, Alzheimer’s sclerosis, senile dementia, skin diseases (protein synthesis control) and other diseases. The presented technology provides extraction of three preparations with different chemical composition and pharmacological activity. Both saturated and unsaturated AGE could be extracted using the property of different solubility in organic solvents for different components of the mixture of hydrolyzed lipids. The main component of the saturated AGE fraction is chimyl alcohol (90.5 %), but the unsaturated fraction contains 54.7 % of monounsaturated AGE. The ω3 PUFA are concentrated to summary 46 % content of eicosapentaenoic acid and docosahexaenoic acid by the method of fatty acids crystallization with carbamide. Comparing with traditional raw materials for АGE and ω3 PUFA production, as shark liver, the liver of gonatid squid is more suitable because of its high and accessible resources, whereas sharks are presented in bycatch only so cannot be considered as a stable source

Comparative assessment for efficiency of isolation of arachidonic acid (20:4n-6) from various sources

Methods of arachidonic acid (AA) isolation from animal and vegetal natural sources are considered. Traditional raw material as the lipids of beef liver and alternative source as the red alga Gracilaria vermiculophylla are tested. The AA was isolated by a sequence of known techniques for concentration of polyunsaturated fatty acids: sedimentation of saturated fatty acids in the form of their lithium salts, iodo-lactonization, and high performance liquid chromatography. All these techniques were applied for isolation of AA from the beef liver lipids, where the AA content did not exceed 7.7 % of total lipids, and the yield of AA with purity of 98.76 % was 50.8 %. The AA content in the algae lipids was significantly higher (> 35 %), while the amount of n-3 polyunsaturated fatty acids was insignificant, so two techniques only were applied (sedimentation of lithium salts and liquid chromatography), and the yield of AA with purity of 97.60 % was 68.3 %. Thus, high-purity arachidonic acid could be isolated from the algae G. vermiculophylla using simple and reproducible procedure. Taking into account the high yield of AA, this method is economically feasible and is proposed for biochemical and medical researches

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
