Injective modules over downup algebras
(Cambridge University Press, 2010)The purpose of this paper is to study finiteness conditions on injective hulls of simple modules over Noetherian downup algebras. We will show that the Noetherian downup algebras A(α, β, γ) which are fully bounded are ... 
Measurement of the Wboson helicity in topquark decays from tt̄ production in lepton+jets events in pp collisions at√s = 7 TeV Th
(Springer, 201310)The Wboson helicity fractions in topquark decays are measured with tt̄ events in the lepton+jets final state, using protonproton collisions at a centreofmass energy of 7TeV, collected in 2011 with the CMS detector at ... 
Determining the Cterminal amino acid of a peptide from MS/MS data
(Proteomass Scientific Society, 201312)Proteomics is currently chiefly based on mass spectrometry (MS) which is the tool of choice to investigate proteins. Two computational approaches to derive the tandem mass spectrum precursor’s sequence are widely employed. ... 
Stressenergy connection: Degravitating the vacuum energy
(World Scientific Publishing, 2013)This talk summarizes recent studies on the gravitational properties of vacuum energy in a nonRiemannian geometry formed by the stressenergy tensor of vacuum, matter and radiation. Postulating that the gravitational effects ... 
Yapay sindirim sıvısında doğal zeolitlerde meydana gelen morfolojik değişmeler
(IEEE, 2009)Doğal zeolitler biyoaktif maddelerdir. Doğal zeolitlerin hayvanlarda biyokütle arttırıcı besi katkı maddesi, insanlarda ülser tedavisinde mide asitliğini tamponlayıcı, asitliği düşürücü ilaç gibi değişik kullanım alanları ... 
The Hirota Method for reactiondiffusion equations with three distinct roots
(AIP Publishing, 2004)The Hirota Method, with modified background is applied to construct exact analytical solutions of nonlinear reactiondiffusion equations of two types. The first equation has only nonlinear reaction part, while the second ... 
Hirota method for solving reactiondiffusion equations with generalized nonlinearity
(World Academic Press, 2006)The Hirota Method is applied to find an exact solitary wave solution to evolution equation with generalized nonlinearity. By introducing the power form of Hirota ansatz the bilinear representation for this equation is ... 
An operator splitting approximation combined with the supg method for transport equations with nonlinear reaction term
(Tech Science Press, 2012)In this work, an operator splitting method is proposed in order to obtain a stable numerical solution for transport equation with nonlinear reaction term. We split the transport equation into a reaction part and an ... 
A conserved linearization approach for solving nonlinear oscillation problems
(Natural Sciences Publishing, 201805)Nonlinear oscillation problems are extensively used in engineering and applied sciences. Due to nonavailability of the analytic solutions, numerical approaches have been used for these equations. In this study, a numerical ... 
Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/c in PbPb collisions at √sNN=5.02 TeV
(Elsevier, 201801)The Fourier coefficients v2 and v3 characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at sNN=5.02 TeV are measured with data collected by the CMS experiment. The ...

Increasing solubility of metal silicates by mixed polymeric antiscalants
(Elsevier, 201901)The increase of silicate solubility is a big challenge for both hot and cold water because it reduces the deposition of metal silicates frequently observed in such systems and causes operational obstacles. The deposition ...
