    In the article are given an analysis of the results of researches carried out for the purpose of selective treatment of the Naphthalane oil fraction boiling at 260-3400C with ionic liquid (IL) -morfolinphormiate synthesized on the basis formic acid + morpholine and - N-methyl-2-pyrrolidon (N-MP) and  as an extractant. The aim is to remove poisonous components -  sulfur compounds and toxic carcinogenic polynuclear aromatic hydrocarbons in order to improve therapeutic properties of Naphthalane oil cut. For this purpose we have used extraction method. On the basis of the conducted researches the role of -N-methyl-2-pyrrolidone and IL-morpholinephormiatee in extraction conditions have been determined in selective treatment of Nafthalan oil, according to the results of spectral analysis residual amount of aromatic hydrocarbons decreased from 18.5% wt accordance to 2%, 1.5%. As well as the amount of sulphur decreased from 0.0354% to 0.010%,  0.011% and 0.019%.In the next stage the treated raffinates with N-methyl-2-pyrrolidone has been purified on silica. In a result amount of aromatic hydrocarbons drastically decrease to be 0.07% and 0.02%. As a result we aquire transparency and at the same time the percentage amount of aromatic hydrocarbons drastically decreased from 2% to 0,07%, 1.5%, to 0.02%. Raffinates obtained in a 2-4 stage dearomatization with N-MP and IL. Raffinate are measured on NMR, UV and IR spectral analysis

    WOS: 000304468700013In this paper we study the fractional maximal operator M-alpha, 0 (1,lambda)(H-n) to the weak modified Morrey space W (L) over tilde (q,lambda) (H-n) if and only if, alpha/Q <= 1 - 1/q <= alpha/(Q - lambda) and from (L) over tilde (p,lambda)(H-n) to (L) over tilde (q,lambda)(H-n) if and only if, alpha/Q <= 1/p - 1/q <= alpha/(Q - lambda). In the limiting case Q-lambda/alpha <= p <= Q/alpha we prove that the operator M-alpha is bounded from (L) over tilde (p,lambda)(H-n) to L-infinity (H-n) and the modified fractional integral operator (I) over tilde (alpha) is bounded from (L) over tilde (p,lambda)(H-n) to BMO(H-n). As applications of the properties of the fundamental solution of sub-Laplacian L on H-n, we prove two Sobolev-Stein embedding theorems on modified Morrey and Besov-modified Morrey spaces in the Heisenberg group setting. As an another application, we prove the boundedness of F alpha, from the Besov-modified Morrey spaces B (L) over tilde (s)(p theta),(lambda)(H-n) to B (L) over tilde (s)(q theta),lambda(H-n)

    WOS: 000325038100011In the article we consider the fractional maximal operator M-alpha, 0 <= alpha < Q on any Carnot group G (i.e., nilpotent stratified Lie group) in the generalized Morrey spaces M-p,M-phi(G), where Q is the homogeneous dimension of G. We find the conditions on the pair (phi(1), phi(2)) which ensures the boundedness of the operator M-alpha from one generalized Morrey space M-p,M-phi 1(G) to another M-q,M-phi 2(G), 1 < p <= q < infinity, 1/p - 1/q = alpha/Q, and from the space M-1,M-phi 1(G) to the weak space WMq,phi 2(G), 1 <= q < infinity, 1 - 1/q = alpha/Q. Also find conditions on the phi which ensure the Adams type boundedness of the M-alpha from M-p,M-phi 1/p(G) to M-q,M-phi 1/q(G) for 1 < p < q < infinity and from M-1,M-phi(G) to WMq,phi 1/q(G) for 1 < q < infinity. In the case b is an element of BMO(G) and 1 < p < q < infinity, find the sufficient conditions on the pair (phi(1), phi(2)) which ensures the boundedness of the kth-order commutator operator M-b,M-alpha,M-k from M-p,M-phi 1(G) to M-q,M-phi 2(G) with 1/p - 1/q = alpha/Q. Also find the sufficient conditions on the phi which ensures the boundedness of the operator M-b,M-alpha,M-k from M-p,M-phi 1/p(G) to M-q,M-phi 1/q(G) for 1 < p < q < infinity. In all the cases the conditions for the boundedness of M-alpha are given it terms of supremal-type inequalities on (phi(1), phi(2)) and phi, which do not assume any assumption on monotonicity of (phi(1), phi(2)) and phi in r. As applications we consider the Schrodinger, operator -Delta(G) + V on G, where the nonnegative potential V belongs to the reverse Holder class B-infinity(G). The M-p,M-phi 1 - M-q,M-phi 2 estimates for the operators V-gamma(-Delta(G) + V)(-beta) and V-gamma del(G)(-Delta(G) + V)(-beta) are obtained.Ahi Evran University Scientific Research ProjectsAhi Evran University [FEN 4001.12.0018, FEN 4001.12.0019]; Science Development Foundation under the President of the Republic of Azerbaijan projectScience Development Foundation (SDF) - Azerbaijan [EIF-2010-1(1)-40/06-1]; Scientific and Technological Research Council of Turkey (TUBITAK Project)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [110T695]Received November 30, 2011; revised March 2, 2013.

    The article provides updated information about the hydrological characteristics, biodiversity and the influence of these and other anthropogenic factors in the Araz River and some of its tributaries in Azerbaijan.Its is revealed that concentration of such unnatural components as heavy metals, phenols, oil products and other pollutants in the water of the river highly increased during last 50-60 years. As a result, the proportion of dissolved oxygen in the water is partly decreased, while the degree of water mineralization increased 2-4 time. Ten species of macrophytes, 34 species of fishes, 28 species of zooplankton organisms belonging to 3 ecological groups and 95 species of macrobenthic organisms, belonging to 14 systematical groups, were found in Araz River. 6 groups (60 species) of macrobenthic organisms were revealed in the faunas of Okhchuchay River and Hakarichay River.Este artículo aporta información actualizada sobre las características hidrológicas, la biodiversidad y lainfluencia de los factores antrópicos en el río Araz y sus tributarios. Los datos revelan altas concentracionesde metales pesados, fenoles, productos derivados de los hidrocarburos y otros productos en el agua del río,que se han incrementado notablemente en los últimos 50-60 años. Como resultado de dichas perturbaciones se han producido ciertos cambios en la composición físico química del agua, particularmente por ejemplo en los niveles de oxígeno disuelto, que han disminuido, así como en los valores de la conductividad, que se han incrementado,entre 2 y 4 veces. La biodiversidad del río Araz incluye 10 especies de macrófitos, 34 de peces, 28 de zooplancton (que pertenecen a 3 grupos ecológicos) y 95 de macroinvertebrados (pertenecientes a 14 grupos sistemáticos). En el caso de los ríos Okhchuchay y Hakarichay, se determinaron 60 especies de macroinvertebrados (pertenecientes a 6 grupos

    In this article is considered hiding process of bits on least significant bits that make up the binary codes of confidential information with using fractal based stego-key. In order to increase resistance against stegoanalysis, it is proposed to use only a part of graphic images not all the pixels of the containers, but only a part determined by the appropriate rule. As a key-image file displaying a Mandelbrot and Julian fractal is used to determine positions of pixels for hiding secret information on least significant pixels of container. So after creation of fractal image as key file, border point of it is changed with according represented rule, then position of pixels is determined with obtained new positions to hiding information in least significant bits
