Calculation of the T-X phase diagram for a mixture of liquid crystals
(Pergamon-Elsevier Science, 2000-12)In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. ... -
Calix[4]amine Langmuir-Blodgett thin film sensing properties against volatile organic compounds
(IOP Publishing LTD, 2019)Thin films of CBAMINE were deposited at air-water interface by the method of Langmuir-Blodgett (LB) technique onto a suitable substrate. Atomic force microscopy technique was used to characterize its thin film properties. ... -
Cation effect on gel-sol transition of kappa carrageenan
(Springer, 2008-04)The steady state fluorescence (SSF) technique was employed to study gel - sol transitions of kappa carrageenan in NaCl, KCl and CaCl2 solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. ... -
Cation effects on phase transition of kappa-iota-carrageenan hybrids: a photon transmission study
(Taylor & Francis Group, 2007)Phase transitions of kappa-iota-carrageenan hybrid in various types of salts were studied using photon transmission technique: NaCl, KCI, MgCl2, CaCl2 and KCl+CaCl2 were chosen as the salt solutions for the carrageenan ... -
The Cauchy problem for a class of two-dimensional nonlocal nonlinear wave equations governing anti-plane shear motions in elastic materials
(IOP Publishing Ltd, 2011-04)This paper is concerned with the analysis of the Cauchy problem of a general class of two-dimensional nonlinear nonlocal wave equations governing anti-plane shear motions in nonlocal elasticity. The nonlocal nature of the ... -
Cement fabrics and optical luminescence ages of beachrock, North Cyprus: Implications for Holocene sea-level changes
(Elsevier Ltd., 2016-05-16)CaCO3-cemented beachrocks are widely found along the northern coast of Cyprus. In this study, we aim to discuss the cementation history of beachrocks at ten particular sites within the context of Holocene sea-level changes. ... -
Cementation characteristics and age of beachrocks in a fresh-water environment, Lake Iznik, NW Turkey
(Elsevier Science BV, 2012-12-01)This paper focuses on the cement characteristics and optical luminescence age of late Pleistocene-Holocene beachrock, exposed on the southeast shore of freshwater Lake Iznik in northwest Turkey, based on field observations, ... -
Ceramic encapsulated latex composites
(Elsevier Inc, 2006-04-15)This work reports the encapsulation of latex particles in Al(2)O(3)-polystyrene (PS) composite films. These films were prepared from PS particles in Al(2)O(3) dispersion at room temperature in various latex contents. ... -
The cerebral blood flow deficits in Parkinson’s disease with mild cognitive impairment using arterial spin labeling MRI
(Springer, 2020-09)Parkinson's disease (PD) with mild cognitive impairment (PD-MCI) is currently diagnosed based on an arbitrarily predefined standard deviation of neuropsychological test scores, and more objective biomarkers for PD-MCI ... -
A certain class of harmonic mappings related to functions of bounded boundary rotation
(Eudoxus Press, 2014-05)Let V(k) be the class of functions with bounded boundary rotation and let S-H be the class of sense-preserving harmonic mappings. In the present paper we investigate a certain class of harmonic mappings related to the ... -
A certain class of starlike log-harmonic mappings
(Elsevier Science BV, 2014-11)In this paper we investigate some properties of log-harmonic starlike mappings. For this aim we use the subordination principle or Lindelof Principle (Lewandowski (1961) [71). -
Characteristic classes of foliations via SAYD-twisted cocycles
(European Mathematical Society, 2015)We find the first non trivial “SAYD-twisted” cyclic cocycle over the groupoid action algebra under the symmetry of the affine linear transformations of the Euclidian space. We apply the cocycle to construct a characteristic ... -
A characteristic map for compact quantum groups
(Springer Heidelberg, 2017-09)We show that if G is a compact Lie group and g is its Lie algebra, then there is a map from the Hopf-cyclic cohomology of the quantum enveloping algebra U-q(g) to the twisted cyclic cohomology of quantum group algebra ... -
Characterization of Bulgarian oil shale kerogen revealed by oxidative degradation
(Elsevier GMBH, Urban & Fischer Verlag, 2009)A 13-step alkaline permanganate degradation of Bulgarian oil shale kerogen concentrate at ambient temperature was carried out. A high yield of oxidation products (90.1%) and a low yield of gaseous products (2.79%) were ... -
Cinsel işlev bozuklukları ve depresyon
(Muhammed YILDIZ, 2019-12-31)Depresyon ile cinsel işlev bozuklukları arasında bir korelasyon olduğu düşüncesi psikologlar ve psikiyatristler tarafından yaygın bir şekilde kabul görmesine karşın bu konuda yeterli çalışma yapılmamış, daha çok sosyal ve ... -
Classification of minimal Lorentzian surfaces in S-2(4) (1) with Constant Gaussian and normal curvatures
(Mathematical Society of The Repulic Of China, 2016-12)In this paper we consider Lorentzian surfaces in the 4-dimensional pseudo Riemannian sphere S-2(4)(1) with index 2 and curvature one. We obtain the complete classification of minimal Lorentzian surfaces S-2(4)(1) whose ... -
Classification of surfaces in a pseudo-sphere with 2-type pseudo-spherical Gauss map
(Wiley-V C H Verlag GMBH, 2017-11)In this article, we study submanifolds in a pseudo-sphere with 2-type pseudo-spherical Gauss map. We give a characterization theorem for Lorentzian surfaces in the pseudosphere S-2(4) subset of E-2(5) with zero mean curvature ... -
A clinical case of treatment-resistant schizophrenia: 60 hospitalizations and 342 ECT sessions in 36 years; lack of social support or undertreatment?
(İstanbul Üniversitesi, 2015-06)It is reported that between 20% and 25% of patients have schizophrenia that is resistant to treatment. The treatment resistance in schizophrenia is defined by many authorities. One of the generally accepted definitions is ... -
