Jet production rates in association with W and Z bosons in pp collisions at √s = 7 TeV
(Springer, 2012)Measurements of jet production rates in association with W and Z bosons for jet transverse momenta above 30 GeV are reported, using a sample of proton-proton collision events recorded by CMS at √s = 7TeV, corresponding to ... -
Kinetic and thermodynamic investigations of strontium ions retention by natural kaolinite and clinoptilolite minerals
(Oldenbourg Verlag, 2005)The current study was devoted to the determination of various thermodynamic and kinetic parameters resulting from the fixation of Sr2+ by natural samples of kaolinite and clinoptilolite minerals. The sorption process ... -
The kinetics of citral hydrogenation over Pd supported on clinoptilolite rich natural zeolite
(Elsevier, 2005-06)The liquid phase hydrogenation of citral has been investigated over Pd (2.42%) supported on clinoptilolite rich natural zeolite catalyst for different reaction conditions. The zeolite support did not affect the active metal ... -
Kinetics of oil dispersion in the absence and presence of block copolymers
(American Institute of Chemical Engineers, 1999-09)A phenomenological model proposed describes droplet breakup in the turbitlently agitated lean oil-in-water dispersions and provides a correlation between the median droplet size in an agitated vessel of standard geometry ... -
Label-free quantitation, an extension to 2DB
(Springer, 2010-04)Determining the differential expression of proteins under different conditions is of major importance in proteomics. Since mass spectrometry-based proteomics is often used to quantify proteins, several labelling strategies ... -
Large energy gaps in Ca C6 from tunneling spectroscopy: Possible evidence of strong-coupling superconductivity
(American Physical Society, 2007-12)Tunneling in Ca C6 crystals reproducibly reveals superconducting gaps Δ of 2.3±0.2 meV that are ∼40% larger than reported earlier. In an isotropic s -wave scenario, that puts Ca C6 into the class of very strongly coupled ... -
Layer- and strain-dependent optoelectronic properties of hexagonal AlN
(American Physical Society, 2015-10)Motivated by the recent synthesis of layered hexagonal aluminum nitride (h-AlN), we investigate its layer- and strain-dependent electronic and optical properties by using first-principles methods. Monolayer h-AlN is a ... -
Layered clay/epoxy nanocomposites: Thermomechanical, flame retardancy, and optical properties
(Wiley, 2008-07)In this study, layered clay/polymer nano-composites were developed based on epoxy resins and montmorillonite as the nanoplatelet reinforcement. Clay particles were treated with hexadecyltrimethylammonium chloride (HTCA) ... -
Lebesgue-Stieltjes measure on time scales
(TÜBİTAK, 2009)The theory of time scales was introduced by Stefan Hilger in his Ph. D. thesis in 1988, supervised by Bernd Auldbach, in order to unify continuous and discrete analysis [5]. Measure theory on time scales was first constructed ... -
Light induced degradation of hydrogenated amorphous silicon - Germanium alloy (a-SiGe:H) thin films
(National Institute of Optoelectronics, 2005-02)Hydrogenated amorphous silicon germanium alloy thin films prepared by Plasma Enhanced Chemical Vapor Deposition (PECVD) with varying Germanium concentrations have been investigated in both the annealed and the light soaked ... -
Linear wave interaction with a vertical cylinder of arbitrary cross section: An asymptotic approach
(American Society of Civil Engineers, 2017-09)An asymptotic approach to the linear problem of regular water waves interacting with a vertical cylinder of an arbitrary cross section is presented. The incident regular wave was one-dimensional, water was of finite depth, ... -
Linking peroxiredoxin and vacuolar-ATPase functions in calorie restriction-mediated life span extension
(Hindawi Publishing Corporation, 2014)Calorie restriction (CR) is an intervention extending the life spans of many organisms. The mechanisms underlying CR-dependent retardation of aging are still poorly understood. Despite mechanisms involving conserved nutrient ... -
Lithium protects against paraquat neurotoxicity by NRF2 activation and miR-34a inhibition in SH-SY5Y cells
(Frontiers Media, 2015-05-28)Lithium is a mood stabilizing agent commonly used for the treatment of bipolar disorder. Here, we investigated the potential neuroprotective effect of lithium against paraquat toxicity and its underlying mechanisms in ... -
Local oxidation nanolithography on Hf thin films using atomic force microscopy (AFM)
(IOP, 2009)Well controlled Hf oxide patterns have been grown on a flat Hf thin film surface produced by the dc magnetron sputtering method on Si and SiOx substrates. These patterns have been created by using the technique of semi-contact ... -
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
(Elsevier, 2015-03)Measurements of two-particle angular correlations between an identified strange hadron (KS0 or Λ/Λ-) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. ... -
Long-term monitoring of polars
(Cambridge University Press, 2011-07)We present long-term observations of magnetic cataclysmic variables AM Her, AN UMa, AR UMa, DP Leo, and V1309 Ori obtained with the ROTSEIIId telescope. All data have been analysed and preliminary results indicate periods ... -
Low-field behavior of Ti-added MgB2/Cu superconducting wires
(IEEE, 2005-06)We report on low-field magnetic properties of Ti-added (0-20 wt.% of Ti) Cu-clad MgB2 superconducting wires. Wires were produced by mixing appropriate amount of Ti and reacted MgB2 powder which was then placed inside Cu ... -
Low-intensity vibrations normalize adipogenesis-induced morphological and molecular changes of adult mesenchymal stem cells
(SAGE Publications, 2017-02)Bone marrow mesenchymal stem cells that are committed to adipogenesis were exposed daily to high-frequency low-intensity mechanical vibrations to understand molecular, morphological and ultrastructural adaptations to ... -
Machine learning methods for microRNA gene prediction
(Humana Press, 2014)MicroRNAs (miRNAs) are single-stranded, small, noncoding RNAs of about 22 nucleotides in length, which control gene expression at the posttranscriptional level through translational inhibition, degradation, adenylation, ... -
Macromolecular changes in nilotinib resistant k562 cells; An in vitro study by fourier transform infrared spectroscopy
(SAGE Publications, 2012-08)Nilotinib is a second generation tyrosine kinase inhibitor which is used in both first and second line treatment of chronic myeloid leukemia (CML). In the present work, the effects of nilotinib resistance on K562 cells ...
