Controlling the growth of particle size and size distribution of silica nanoparticles by the thin film structure
(Springer, 2012)Nanostructured silicondioxide thin films were prepared by sol-gel spin coating technique. The SiO2 films were made using a conventional mixture of tetraethoxysilane (TEOS) deionized water and ethanol with various NH3/TEOS ... -
Corrected Panel-Reactive Antibody Positivity Rates for Hypersensitized Patients in Turkish Population With Calculated Panel-Reactive Antibody Software
(Elsevier Science Inc, 2017)however the rate was 86.2% using the cPRA. Discussion. cPRA shows the rate of the rejected donors according to all unacceptable antigens. The need for a list of unacceptable antigens in place of the PRA positivity rate is ... -
Correlation of Experimental Liquid-Liquid Equilibrium Data for Ternary Systems Using NRTL and GMDH-Type Neural Network
(Amer Chemical Soc, 2017)In this work liquid liquid equilibrium (LLE) data for the ternary systems (water + propionic acid + solvent) were experimentally obtained at atmospheric pressure and 298.2 K. The ternary systems show type-1 behavior of ... -
Correlation of ternary liquid--liquid equilibrium data using neural network-based activity coefficient model
(Springer, 2014)Liquid--liquid equilibrium (LLE) data are important in chemical industry for the design of separation equipments and it is troublesome to determine experimentally. In this paper a new method for correlation of ternary LLE ... -
Cosmic ray intensity variation during a CME
(Pergamon-Elsevier Science Ltd, 2002)The June 6 2000 coronal mass ejection was an exceptional full halo which made it possible to measure cosmic ray (CR) decrease with a simple experimental set-up. Variation in the local secondary cosmic ray density has been ... -
Coulomb corrections in the lepton-pair production in ultrarelativistic nuclear collisions
(Amer Physical Soc., 2005)We solve the perturbative electron-positron pair production exactly by calculating the second-order Feynman diagrams. We compare our result with Born methods that include Coulomb corrections. We find that a small-momentum ... -
Critical Exponents of Gelation and Conductivity in Polyacrylamide Gels Doped by Multiwalled Carbon Nanotubes
(Taylor & Francis Ltd, 2010)Polyacrylamide (PAM) doped by multiwalled carbon nanotube (MWNT) gels were prepared with different amounts of MWNTs varying in the range between 0.1 and 15 wt%. The PAM-MWNT composite gels were characterized by the steady ... -
Critical Exponents of Kappa Carrageenan in the Coil-Helix and Helix-Coil Hysteresis Loops
(Taylor & Francis Inc, 2009)The steady-state fluorescence technique was used to study coil-helix (sol-gel) and helix-coil (gel-sol) transitions of the kappa carrageenan-water system with various carrageenan contents. Fluorescence (I) and scattered ... -
Critical Exponents of Photoinitiated Gelation at Different Light Intensities
(Taylor & Francis Inc, 2009)A photo-differential scanning calorimetric (Photo-DSC) technique was used to study the photoinitiated radical polymerization of a 75% epoxy diacrylate (EA) and 25% tripropyleneglycoldiacrylate (TPGDA) mixture with ... -
Critical Exponents of Thermal Phase Transitions of kappa-Carrageenan in Various Salt Solutions
(Wiley-VCH Verlag GmbH, 2009)The steady state fluorescence (SSF) technique was employed to study the phase transitions Of kappa-carrageenan in NaCl and KCl solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. Scattered ... -
Critical phenomenon during photoinitiated gelation at different temperatures: A Photo-DSC study
(Elsevier Science, 2011)The behaviour of photoinitiated radical polymerization of an 80 wt% epoxy diacrylate (EA) and 20 wt% tripropyleneglycoldiacrylate (TPGDA) mixture with 2-mercaptothioxanthone (TX-SH) photoinitiator was studied at different ... -
The critical point of a sigmoidal curve
(Babeș-Bolyai University, 2020)Let y(t) be a monotone increasing curve with lim(t ->+/-infinity) y((n))(t) = 0 for all n and let t(n) be the location of the global extremum of the nth derivative y((n))(t). Under certain assumptions on the Fourier and ... -
Crossover from Vibrational to Rotational Collectivity in Heavy Nuclei in the Shell-Model Monte Carlo Approach
(Amer Physical Soc., 2013)Heavy nuclei exhibit a crossover from vibrational to rotational collectivity as the number of neutrons or protons increases from shell closure towards midshell but the microscopic description of this crossover has been a ... -
A crude marriage: Iraq Turkey and the Kirkuk-Ceyhan oil pipeline
(Routledge Journals Taylor & Francis Ltd, 2017)Since the discovery of oil at Kirkuk in northern Iraq oil has shaped relations between Iraq and Turkey as the former needed markets and export routes to the Mediterranean and the latter reliable sources of supply. This ... -
