Gabriel-Cromwell aziridination of amino sugars; chiral ferrocenoyl-aziridinyl sugar synthesis and their biological evaluation
(Elsevier Sci Ltd, 2021)
N-sugar substituted chiral aziridines were synthesized via Gabriel-Cromwell reaction. Novel pure diastereomers of aziridine derivatives (4 diastereomers) were readily obtained in high yields and their structures were ...
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 ...
The role of cystatin C, neutrophil-lymphocyte ratio and platelet-lymphocyte ratio in the evaluation of kidney function in women with preeclampsia
(Elsevier Taiwan, 2021)
Objective: We aimed to compare the diagnostic efficiency of cystatin C with traditional kidney markers in preeclampsia and to evaluate the relationship of these markers with neutrophil-lymphocyte and thrombocyte-lymphocyte ...
Geoid undulation prediction using ANNs (RBFNN and GRNN), multiple linear regression (MLR), and interpolation methods: A comparative study
(Univ Nacional De Colombia, 2021)
This study evaluated different methods for geoid undulation prediction and included two types of artificial neural networks (ANNs) -the radial basis function neural network (RBFNN) and the generalized regression neural ...
Social isolation, anxiety, mental well-being and push travel motivation: the case of COVID-19 in Turkey
(Routledge Journals, Taylor & Francis Ltd, 2021)
This study investigates the effects of social isolation, anxiety, and mental well-being perceptions on push travel motivations, in the context of the COVID-19 crisis affecting individuals living in Turkey. The reason for ...
A novel approach regarding the fixed points of repelling nature
(Pergamon-Elsevier Science Ltd, 2021)
Although there are various numerical techniques to find the stable equilibria of a nonlinear system in scientific computing, no widely-used computational approach has been encountered to discover the unstable equilibria ...
Application of organic photovoltaic cell: poly(2-aminofluoren)/multi-walled carbon nanotube composites
(Springer, 2021)
This work presents the 2-aminofluorene polymer matrix based on the multi-walled carbon nanotube module for an alternative energy conversion system as a photovoltaic solar cell. The properties of the MWCNT-PAF composite ...
Current Approach to Surgical Treatment of Ectopic Pregnancy
(Springer, 2021)
Purpose of Review The purpose of this review is to update readers on recent surgical treatment modalities of ectopic pregnancies (EP) and their advantages vs disadvantages. Recent Findings EP was generally managed with ...
Some Ciric Type Periodic Point Results with Q-function on Quasi Metric Spaces
(Amer Inst Physics, 2021)
In this paper, we proved a Ciric type periodic point result with a Q-function on quasi metric spaces. We also give an illustrative example to show the effectiveness of our main result.
Experimental and Numerical Study of Cutting Force Performance of Wave Form End Mills on Gray Cast Iron
(Springer Heidelberg, 2021)
Milling is a machining method used extensively nowadays in the manufacturing industry. In the milling process, one of the most important parameters affecting the machining performance is cutting tool geometry. In general, ...
