Faunistic studies on Carabidae, Staphylinidae, Elateridae, Cleridae, Cerambycidae and Chrysomelidae (Coleoptera) Families of Çataldağ (Balıkesir-Susurluk) province, Western Turkey
(Kahramanmaraş Sutcu Imam Universitesi Rektorlugu, 2020)This study was conducted between April and November for two years in 2017-2018, by sifting plant debris (Reitter method) in order to identify the beetle fauna (Coleoptera) living on the ground in the old oak and beech ... -
Degree of approximation by means of hexagonal Fourier series
(Scientific Technical Research Council Turkey-Tubitak, 2020)Let f be a continuous function which is periodic with respect to the hexagon lattice, and let A be a lower triangular infinite matrix of nonnegative real numbers with nonincreasing rows. The degree of approximation of the ... -
On approximation of hexagonal Fourier series in the generalized Holder metric
(Hacettepe Univ, 2020)Let f be an H-periodic continuous function. The approximation order of the function f by deferred Cesaro means of its hexagonal Fourier series is estimated in uniform and generalized Holder metrics. -
Construction of arithmetic secret sharing schemes by using torsion limits
(Hacettepe Univ, 2020)Cascudo, Cramer, and Xing [Torsion limits and Riemann-Roch systems for function fields and applications, IEEE Trans. Inf. Theory, 2014] gave a construction of arithmetic secret sharing schemes by using the torsion limits ... -
On isoparametric linear Weingarten hypersurfaces in Riemannian and Lorentzian space forms
(Amer Mathematical Soc, 2020)Linear Weingarten hypersurfaces have been extensively studied by various aspects in the literature. In the present paper, we deal with the classifications of isoparametric linear Weingarten hypersurfaces in Riemannian and ... -
System analysis of HIV infection model with CD4(+)T under non-singular kernel derivative
(Walter De Gruyter GMBH, 2020)Infectious diseases have caused the death of many people throughout the world for centuries. For this purpose, many researchers have investigated these diseases for establishing new treatment and protective measures. The ... -
Synthesis, characterization and enviromental application of grafted silica gel
(Parlar Scientific Publications (P S P), 2020)The aims of this study are i.to modify the silica gel (SG) surface with N-(2-methoxybenzylidene)-3-(triethoxysily)propan-1-amine (MBTPA) to improve the adsorption properties of SG, ii. to characterize the modified sample ... -
The effects of cardiac drugs on human erythrocyte carbonic anhydrase I and II isozymes
(Taylor and Francis Ltd, 2020)Cardiovascular diseases are the leading cause of mortality worldwide. In recent years, the relationship between carbonic anhydrase inhibitors and atherosclerosis has attracted attention. In this study, we aimed to determine ... -
Effects of kinetin on biological parameters and hemocytes of Achroia grisella (Lepidoptera: Pyralidae)

Bilateral-type solutions to the fixed-circle problem with rectified linear units application
(Scientific Technical Research Council Turkey-Tubitak, 2020)In this paper, we prove new fixed-circle (resp. fixed-disc) results using the bilateral type contractions on a metric space. To do this, we modify some known contractive conditions called the Jaggi-type bilateral contraction ... -
A new solution to the discontinuity problem on metric spaces
(Scientific Technical Research Council Turkey-Tubitak, 2020)We study on the Rhoades' question concerning the discontinuity problem at fixed point for a self-mapping T of a metric space. We obtain a new solution to this question. Our result generalizes some recent theorems existing ... -
Some generalized fixed-point theorems on complex valued s-metric spaces
