Seasonal variation in plant biomass in a salt marsh community in northern Turkey
(2007)Seasonal pattern in above- and belowground live and dead biomass in a salt marsh community was investigated. Multiple peaks were observed in terms of all biomass types. Maximum aboveground live and dead biomass was observed ... -
Sediment distribution coefficients (K-d) and bioaccumulation factors (BAF) in biota for natural radionuclides in eastern Black Sea coast of Turkey
(Elsevier, 2019)y Germanium (HPGe) detector was used to measure natural (Ra-226, Th-232 K-40) radioactivity levels in sediment and seawater samples, and soft tissues of Mediterranean mussels (Mytilus galloprovincialis) of three different ... -
Seed morphology of epilobium and chamaenerion (Onagraceae) in Turkey
(Magnolia Press, 2017)Macro- and micro-morphological features of seeds belonging to 26 taxa from Turkey were observed under the light and scanning electron microscopy. Present findings partly agree with segregation of Epilobium and Chamaenerion ... -
Selective radiation measurement for safety evaluation on base stations
(Gazi University, 2013)In this paper, general information about unionized radiation, standards and measurement routines for wireless communication systems, electromagnetic fields and antenna structures are given. The safety of mobile phones has ... -
Semi-conductive carbon from industrial tea waste biomass for a p-n junction
(Springer, 2024)Some semiconducting carbonaceous material was developed from industrial tea waste biomass by catalytic pyrolysis and heteroatom doping; then, a p-n junction was realized on an n-type Si substrate. I-V characteristics of ... -
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 ... -
