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 Conformational Analysis and Vibrational Spectroscopic Investigation on 1,2bis(ocarboxyphenoxy) Ethane Molecule

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 new correlation with lower kilohertz quasiperiodic oscillation frequency in the ensemble of lowmass xray binaries

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 ... 
A possible link between kHz quasiperiodic oscillations and the magnetospheric boundary
