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
(Tsing Hua Univ, 2020)In this paper, we define new contractive conditions on a complex valued S-metric space. These contractive conditions generalize the classical Rhoades' contractive condition, Nemytskii-Edelstein contractive condition and ... -
A research on native plant taxa with invasive character in flora of Balikesir
(Kahramanmaraş Sutcu Imam Universitesi Rektorlugu, 2020)In this study, native plant taxa with invasive character that spread in flora of Balikesir were determined. Their distribution depending on habitat types and their ecological risks were revealed. For this purpose, in ... -
The effect of halogen substitution on the bowl-to-bowl inversion, molecular structure and electronic properties of sumanene
(Univ Babes-Bolyai, 2020)Halogen (X: F, Cl, and Br) substituted sumanene derivatives were subjected to a detailed computational study, exploring the molecular structure, bowl-depths, bowl-to-bowl inversion dynamics, and electronic properties. ... -
Inhibitory effects of anticancer drugs on cytosolic carbonic anhydrase isozymes
(Parlar Scientific Publications (P S P), 2020)Anticancer drugs are widely used cancer treatment. Human carbonic anhydrase I and II were shown widely distribution with erythrocytes so it is important to understand how effect is anticancer drugs these isozymes. In this ... -
Grafted silica gel for removal of heavy metal ions
(Parlar Scientific Publications (P S P), 2020)In this study, the silica gel (SG) surface was activated and then, immobilized with N-(2-chlorobenzylidenc)-3-(triethoxysil)propan-1 -amine (CBTPA) to improve its adsorption properties against heavy metal ions. The prepared ... -
An integral formula for bi-slant submanifolds in complex space forms
(Hacettepe Univ, 2020)The present paper deals with bi-slant submanifolds in complex space forms. We obtain an integral formula of Simons' type for bi-slant submanifolds of a complex space form with positive constant holomorphic sectional ... -
A fractional mixing propagation model of computer viruses and countermeasures involving mittag-leffler type kernel
(Springer International Publishing Ag, 2020)Countermeasures are recognized as a remarkable effort to comprehend the computer virus problem and estimate its forthcoming actions. Countermeasure-Competing (CMC) strategy is a conception comprising viruses and countermeasures. ... -
Novel β-lactam compounds as activators for polyphenoloxidase
(Wiley V C H Verlag GMBH, 2020)A copper-containing enzyme polyphenol oxidase (other name is tyrosinase) plays crucial role in melanin biosynthesis, as a compound responsible for human pigmentation. Non controlled loss of melanin can cause hypopigmentation ... -
The chemical components, antioxidant and anticancer activities of ziziphus jujube extracts from Turkey
(Agrimedia GMBH, 2020)The bioactive components which are nutritionally and medically important of jujube fruit have been shown to vary with growing conditions. In this study, the cytotoxic effect of Ziziphus jujube fruit, which is in two different ... -
Immobilization xanthine oxidase on interdigitated electrode for biosensor investigation
(Parlar Scientific Publications (P S P), 2020)Biosensors can be developed using different biological materials and immobilization technologies. Interest in immobilization techniques has increased because they allow for the improvement of some stability characteristics ... -
Upregulation of PSMD4 gene by hypoxia in prostate cancer cells
(Tubitak Scientific & Technical Research Council Turkey,, 2020)Ubiquitin-proteasome pathways have a crucial role in tumor progression. PSMD4 (Rpn10, 26S proteasome non-ATPase subunit 4), which is a subunit of the regulatory particle, is a major ubiquitin (Ub) receptor of 26S proteasome. ... -
Fractional order mixed difference operator and its applications in angular approximation
(Hacettepe Univ, 2020)Lebesgue spaces are considered with Muckenhoupt weights. Fractional order mixed difference operator is investigated to obtain mixed fractional modulus of smoothness in these spaces. Using this modulus of smoothness we give ... -
Synthesis and optical characterization of bipod carbazole derivatives
(Walter De Gruyter GMBH, 2020)In this study, some new biscarbazole derivatives were synthesized for the purpose of being used in OLED technologies and related areas. The following compounds: {1,2-bis(2-(3,6-diphenyl-9H-carbazole-9-yl) ethoxy)ethane ... -
The effect of photomultiplier tube glass entrance window on plastic scintillator cast sheet photon dosimetry: A Monte Carlo study
(IOP Publishing, 2020)Plastic scintillators are commonly used for medical dosimetry due to the density and effective atomic numbers that are closer to human soft tissue. When a photomultiplier tube (PMT) is used with a thin scintillator, reflected ... -
