A Certain Class of Harmonic Mappings Related to Functions of Bounded Boundary Rotation
(Eudoxus Press, Llc, 1424 Beaver Trail Drive, Cordova, Tn 38016 Usa, 201405)Let V(k) be the class of functions with bounded boundary rotation and let SH be the class of sensepreserving harmonic mappings. In the present paper we investigate a certain class of harmonic mappings related to the ... 
A certain class of starlike logharmonic mappings
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 201411)In this paper we investigate some properties of logharmonic starlike mappings. For this aim we use the subordination principle or Lindelof Principle (Lewandowski (1961) [71). (C) 2014 Elsevier B.V. All rights reserved. 
A Characterization for Convex Functions of Complex Order b
(İstanbul University Science Faculty, 1997)The main purpose of this note is tö give a new characterization for convex functions of complex order b. It should be noticed that by giving specific values to b we obtain new characterizations of important subclasses of ... 
A combinatorial discussion on finite dimensional Leavitt path algebras
(Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2014)Any finite dimensional semisimple algebra A over a field K is isomorphic to a direct sum of finite dimensional full matrix rings over suitable division rings. We shall consider the direct sum of finite dimensional full ... 
A comparative study of auditory and visual event related coherences

A Conformational Analysis and Vibrational Spectroscopic Investigation on 1,2bis(ocarboxyphenoxy) Ethane Molecule
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 201201)The minima on the potential energy surface of 1,2bis(ocarboxyphenoxy)ethane (CPE) molecule in its electronic ground state were searched by a molecular dynamics simulation performed with MM2 force field. For each of the ... 
A Fouriertransform infrared and laserRaman spectroscopic investigation of 4,4′bipyridyltransition metal(II) tetracyanonickelate clathrates
(199603)The FTIR and Raman spectra are reported of M(4,4bipyridyl)Ni(CN)4nG (where M = Mn, Fe, Co, Cu or Zn and G = benzene or aniline;n = 0–2) clathrates. The host structure consists of a threedimensional rigid lattice formed ... 
A mechanism for the dependence of sunspot group tilt angles on cycle strength
(Iop Publıshıng Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 20151101)The average tilt angle of sunspot groups emerging throughout the solar cycle determines the net magnetic flux crossing the equator, which is correlated with the strength of the subsequent cycle. I suggest that a deepseated, ... 
A Molecular Mechanics Conformational Study of Peptide T
(Elsevier, 19970120)Conformational behaviour of peptide T, a competitor of the human immunodeficiency virus in the binding to human T cells, was investigated by theoretical conformational analysis. Two types of conformations are found to be ... 
A Natural Limit on the Observable Periods of Anomalous Xray Pulsars and Soft Gammaray Repeaters
(Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 117474501 USA, 2011)We investigate the dependence of the evolution of neutron stars with fallback disks on the strength of the magnetic dipole field of the star. Using the same model as employed by Ertan et al. (2009), we obtain model curves ... 
A new correlation with lower kilohertz quasiperiodic oscillation frequency in the ensemble of lowmass xray binaries
(Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 20161101)We study the dependence of kilohertz quasiperiodic oscillation (kHz QPO) frequency on accretionrelated parameters in the ensemble of neutronstar lowmass Xray binaries. Based on the mass accretion rate, M, and the ... 
A new hybrid nonlinear congruential number generator based on higher functional power of logistic maps
(PERGAMONELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 20091030)We propose a nonlinear congruential pseudorandom number generator consisting Of summation of higher order composition of random logistic maps under certain congruential mappings. We change both bifurcation parameters of ... 
A new method for calculating fuel consumption and displacement of a ship in maritime transport
(Taylor & Francis As, Karl Johans Gate 5, No0154 Oslo, Norway, 20171211)Fuel consumption is the most important parameter which is effected by the petrol prices. Optimization of the sailing speed decreases the fuel cost because it is proportional to the sailing speed. In this study, the present ... 
A Note On A Problem Of Abramovich, Aliprantis And Burkinshaw
(Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 201109)Let B and T be two positive operators on a Banach lattice such that B is compactfriendly and T is locally quasinilpotent. Introducing the concept of positive quasisimilarity, we prove that T has a nontrivial closed ...
