Interspecific and intraspecific size and shape variation in skull of two closely related species Bufo bufo (Linnaeus, 1758) and Bufo verrucosissimus (Pallas, 1814) from Turkey
(TUBİTAK Scientific & Technical Research Council Turkey, 2021)Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans ... -
Contribution to the taxonomy of little known Tragopogon species endemic to Turkey
(Wiley, 2021)In the present paper, two little-known species (T. olympicus Boiss. and T. pichleri Boiss.) endemic to Turkey are evaluated in terms of morphology based on numerous authentic and/or new collections. Additionally, the ... -
Conventional and microwave-assisted synthesis of novel 1,2,4-triazole derivatives containing tryptamine skeleton and evaluation of antimicrobial activity
(Bentham Science Publishing, 2021)1,2,4-Triazole-3-one (3) obtained from tryptamine was transformed to the corresponding carbox(thio)amides via several steps (6a-d). Their reaction with sodium hydroxide performed the 1,2,4triazole derivatives (7a-d). ... -
Evaluation of color stability of experimental dental composite resins prepared from Bis-EFMA, a novel monomer system
(Technical Assoc Photopolymers JAPAN, 2021)Color stabilities of experimental composite resins based on Bis-EFMA (a novel bisphenol A [BPA]-free monomer system) with 3M ESPE FiltekTM Z250 (FZ) and experimental composite resins based on bisphenol A-glycidyl methacrylate ... -
Three new dihydroisocoumarin glycosides with antimicrobial activities from Scorzonera aucheriana
(Elsevier, 2021)Three new dihydroisocoumarin glycosides (iso-scorzopygmaecoside, scorzoaucherioside I, and scorzoaucherioside II) together with five known compounds (scorzopygmaecoside, scorzocreticoside II, 3,5-O-dicaffeoyl-epiquinic ... -
On the dynamical behavior of nonlinear Fitzhugh-Nagumo and Bateman-Burger equations in quantum model using Sinc collocation scheme
(Springer, 2021)The main objective of this study is to numerically investigate the dynamical behavior of nonlinear Fitzhugh-Nagumo and Bateman-Burger systems through the Sinc collocation method by means of the theta-weighted scheme on ... -

Generating methods for principal topologies on bounded lattices
(Kybernetika, 2021)In this paper, some generating methods for principal topology are introduced by means of some logical operators such as uninorms and triangular norms and their properties are investigated. Defining a pre-order obtained ... -
Magnetic levitation force and trapped field properties of multiseeded YBCO with triangular arrangement of seeds
(Wiley, 2021)Although there are studies in literature using different number of seeds with different arrangements, especially line and rectangular, it is seen that there is no detailed study handling the levitation force together with ... -
Comparison of electrostatic potential obtained from different atomic point charges calculation methods for a large set of molecules
(World Stientific Publishing, 2021)The Electrostatic Potential is of great importance in chemical reactivity since it is closely related to many of molecular properties. Despite the fact that there are significant improvements in the quantum mechanical ... -
Correlation coefficients of simplified neutrosophic multiplicative sets and their applications in clustering analysis
(Springer, 2021)The use of fuzzy sets, intuitionistic fuzzy sets and neutrosophic sets can often handle with real-life problems that contain incomplete and uncertain information. The 0-1 scale is used to deal with such information which ... -
