A semi-Markovian renewal reward process with (g) distributed demand
(2020)We consider a classical semi-Markovian stochastic model of type (s, S) with Logistic distributed demand random variables. Logistic distribution is a member of special distribution class known as (g) that encounters in many ... -
Sensitivity analysis and random dynamics for a mathematical model of tuberculosis transmission
(Taylor & Francis Ltd., 2023)In this study, a recent mathematical model for the spread of tuberculosis disease will be analyzed under random conditions. The sensitivity of the basic reproduction number to the changes in the parameters will be analyzed ... -
Sequential forward mother wavelet selection method for mental workload assessment on N-back task using photoplethysmography signals
(Elsevier, 2021)The increasing demands of a cognitive task require additional brain resources. This demand, known as mental workload, can lead to deteriorated task performance. Therefore, assessment of mental workload can provide a proper ... -
Serret-frenet formulas for octonionic curves
(Soc Paranaense Matematica, 2020)In this paper, we define spatial octonionic curves (SOC) in R( )(7)and octonionic curves (OC) in R-8 by using octonions. Firstly, we determine Serret-Frenet equations, and curvatures of the SOC in R-7. Then, Serret-Frenet ... -
Sexual shape dimorphism in Bufo verrucosissimus (Pallas, 1814) from Lake Borçka Karagöl, Türkiye
(Hungarian Natural History Museum, 2023)Sexual dimorphism, i.e., differences in morphology between sexes of a species caused by intersexual differences in the strength or direction of sexual or natural selection, is preva-lent throughout the animal kingdom. ... -
Sexual size and shape dimorphism in the Near Eastern fire salamander, Salamandra infraimmaculata (Caudata: Salamandridae)
(Brill, 2017)Sexual dimorphism, phenotypic difference between males and females of the same species, has been demonstrated in many invertebrates and vertebrates. in many of these studies, which were especially conducted on amphibians, ... -
Sexual size and shape dimorphism in Turkish common toads (Bufo bufo Linnaeus 1758)
(Wiley, 2021)Differences in male and female traits (sexual dimorphism [SD]) are widespread in animals. Dimorphism in morphological characters evolves under the effect of environmental and genetic factors and is shaped by natural and ... -
Shakespearean theatrical works in relation to contemporary social practices of honour-based violence
(Shanghai Normal University, 2014)In his comedies as well as tragedies, Shakespeare confronts the themes of honour and shame, male social standing, female chastity and subordination of women, questioning the prevailing patriarchal attitudes of his time, ... -
Shape-preserving properties of the limit q-Durrmeyer operator
(Elsevier, 2024)The present work aims to establish the shape-preserving properties of the limit q-Durrmeyer operator, Dq for 0<q<1. It has been proved that the operator is monotonicity- and convexity-preserving. What is more, it maps a ... -
Silorane-based composite: Depth of cure, surface hardness, degree of conversion, and cervical microleakage in class II cavities
(Wiley, 2011)Objective: The purpose of this study was to determine the depth of cure, degree of conversion (DC), hardness, and cervical sealing ability of silorane-based composite (Filtek Silorane [FS; 3M, Seefeld, Germany]) and to ... -
A simple and efficient synthesis of benzimidazoles containing piperazine or morpholine skeleton at C-6 position as glucosidase inhibitors with antioxidant activity
(Academic Press Inc Elsevier Science, 2018)A novel 2-(aryl)-6-morpholin-4-yl(or 4-methylpiperazin-1-yl)-1H-benzimidazole derivatives were designed and expeditiously synthesized starting from 5-morpholin-4-yl(or 4-methylpiperazin-1-yl)-2-nitroaniline with various ... -
A simple and efficient synthesis of novel inhibitors of alpha-glucosidase based on benzimidazole skeleton and molecular docking studies
(Academic Press Inc Elsevier Science, 2016)A novel series of benzimidazole derivatives were prepared starting from o-phenylenediamine and 4-nitro-o-phenylenediamine with iminoester hydrochlorides. Acidic proton in benzimidazole was exchanged with ethyl bromoacetate, ... -
A simple neuro-Heuristic computational intelligence algorithm for thin film flow equation arising in physical models
(Ieee, 2017)In this study, computational method are used for finding the approximation in the solution of thin film flow problem using stochastic solver like genetic algorithm (GA) and pattern search (PS). the mathematical model is ... -
A simplified neutrosophic multiplicative set-based TODIM using water-filling algorithm for the determination of weights
(Wiley, 2020)Due to the technological developments around the world, the amount of information that researchers work on increases continuously. This information density contains incomplete and uncertain data that cannot be fully expressed ... -

Simultaneous separation and preconcentration of Cd(II), Co(II), and Ni(II) ions in environmental samples by carrier element-free coprecipitation method prior to their flame atomic absorption spectrometric determination
(Taylor & Francis Inc, 2015)In the present study, Cd(II), Co(II), and Ni(II) ions were separated and preconcentrated via carrier element-free coprecipitation (CEFC) method by using an organic coprecipitating agent, 1,2-bis-(2-tosyl ethoxy) benzene ... -
Single-molecule-resolution ultrafast near-field optical microscopy via plasmon lifetime extension
(AIP Publishing, 2021)Metal nanostructures support plasmon oscillations on their surfaces, which normally decay very quickly. Nevertheless, the lifetime of these oscillations can be extended near a longer lifetime particle, e.g., a molecule. ...
