(Gazi Universitesi, Turk Kulturu ve Haci Bektas Veli, 2015)Sheikh Safiyuddin Erdebili is the founder of Erdebil sect in Safavid period and the issue of being a sayyid and Shiite for him has not been explained clearly until today. Some historians suppose that he is a Sunni and ... -
KILLING MAGNETIC FLUX SURFACES IN EUCLIDEAN 3-SPACE
(HONAM MATHEMATICAL SOC, 2019)In this paper, we give a geometric approach to Killing magnetic flux surfaces in Euclidean 3-space and solve the differential equations which expressed the mentioned surfaces. Furthermore we give some examples and draw ... -
Kinematic equations of Lorentzian magnetic flux tubes based on split quaternion algebra
(Springer Heidelberg, 2021)The aim of the paper is to present a new geometric viewpoint for magnetic flux tubes (MFTs) in the three-dimensional Lorentzian space through split quaternion algebra. For this, we prove that an MFT can be completely ... -
A kinematic model of the Rytov's law in the optical fiber via split quaternions: application to electromagnetic theory
(Springer Heidelberg, 2022)In this paper, we analyze the homothetic motion of the polarization plane traveling along the linearly polarized light wave ((LPL)-wave) in the optical fiber on the condition that the angle between the polarization vector ... -
Kinematic modeling of Rytov's law and electromagnetic curves in the optical fiber based on elliptical quaternion algebra
(Elsevier Gmbh, 2021)In this paper, we aim a kinematic method to investigate the behavior of polarized light in an optical fiber. Geometric phase equations are obtained using elliptic quaternions. The behavior of polarized light is studied for ... -
Kinematical modeling of circular and elliptical polarization of the polarized light via screw transformation
(Iop Publishing Ltd, 2022)In this paper, it is shown that the motion of a polarized light wave in an optical fiber has a special meaning that relates the scalar and vector part of the dual quaternion to the kinematics concept of a screw. We describe ... -
Kinetics of CO2 capture by carbon dioxide binding organic liquids: Experimental and molecular modelling studies
(ELSEVIER SCI LTD, 2016)In the scope of this work, new carbon dioxide binding organic liquids (CO(2)BOLs) were developed and kinetic parameters in terms of pseudo first-order rate constants for homogenous reaction between CO2 and CO(2)BOLs in ... -
KW-Type Nonlinear Contractions and Their Best Proximity Points
(Taylor & Francis Inc, 2021)In this paper, we present two main results about best proximity points for multivalued mappings. First, taking into account Klim and Wardowski's approach in fixed-point theory, we obtain a new result for multivalued mappings ... -
The laboratory evaluation of insecticidal activities and phytochemical analysis of Marrubium astracanicum Jacq. subsp. astracanicum Jacq. against Callosobruchus chinensis (L.) and Callosobruchus maculatus (F.)
(Elsevier, 2023)Callosobruchus spp. as the important pests of legumes and synthetic insecticides are often used to control them. Due to many side effects of synthetic insecticides, the utilization of plant extracts as an alternative control ... -
Lack of association between VNTR variant of the circadian gene (PER3) and major depressive disorder in a sample of a Turkish population
(Taylor & Francis Inc, 2023)Major depressive disorder (MDD), which is a prevalent psychiatric disorder, is characterized by sleep-wake disturbances. An underlying circadian rhythm disorder mainly may cause these disturbances. The study presented here ... -
