Disaster and emergency preparedness in Istanbul museums
(Routledge Journals, Taylor & Francis Ltd, 2021)Istanbul is a high-risk city in terms of disasters, as well as having museums hosting many cultural heritage artifacts. The purpose of this study is to analyze the preparation level of museums in Istanbul for disaster and ... -
Tunable electronic and magnetic properties of graphene/carbon-nitride van der Waals heterostructures
(Elsevier, 2020)In this paper, we explore the electronic properties of C3N, C3N4 and C4N3 and graphene (Gr) van der Waals heterostructures by conducing extensive first-principles calculations. The acquired results show that these ... -
AFM induced diffusion of large scale mobile HOPG defects
(Springer Heidelberg, 2019)Defects on crystal and/or thin film surfaces play an important role in their physical and chemical properties. Diffusion or motion of such structures results in microstructural dynamic changes. The diffusion of single ... -
Drying behavior of prina (crude olive cake) using different types of dryers
(Taylor & Francis Inc, 2016)The purpose of this research is to investigate the drying kinetics and determine the suitable drying method of prina, which is obtained after pressing of olives in olive oil factories, and which cannot be used efficiently ... -
Novel dendrimers containing redox mediator: Enzyme immobilization and applications
(Elsevier Science Bv, 2019)In this study, new dendrimers with a ferrocene core were produced by means of a divergent method for the immobilization of the glucose oxidase enzyme (GOx). Pt(II) and Pt(IV) ions were attached to the terminal groups of ... -
Dynamics of a Second-order System of Nonlinear Difference Equations
(Semnan Univ, 2020)In this paper, we investigate the equilibrium points, stability of two equilibrium points, convergences of negative equilibrium point, periodic solutions, and existence of bounded or unbounded solutions of a system of ... -
A Comparative Study of Statistical Methods for Daily Streamflow Estimation at Ungauged Basins in Turkey
(Mdpi, 2020)In this study, a comparative evaluation of the statistical methods for daily streamflow estimation at ungauged basins is presented. The single donor station drainage area ratio (DAR) method, the multiple-donor stations ... -
The environmental impact of governance: a system-generalized method of moments analysis
(Springer Heidelberg, 2021)To investigate the role of governance on environmental quality, two hypotheses are developed; when good governance practices dominate governance structures, then improvement in governance levels leads to better environmental ... -
Dating currency crises and designing early warning systems: Meta-possibilistic fuzzy index functions
(Wiley, 2020)In order to analyse the currency crises in Turkey over the period of January 1990 and October 2019, we first dated currency crises with meta-possibilistic fuzzy index functions. Then, we determined the significant predictors ... -
Oxygen Vacancies in the Single Layer of Ti(2)CO(2)MXene: Effects of Gating Voltage, Mechanical Strain, and Atomic Impurities
(Wiley-V C H Verlag Gmbh, 2020)Herein, using first-principles calculations the structural and electronic properties of the Ti(2)CO(2)MXene monolayer with and without oxygen vacancies are systematically investigated with different defect concentrations ... -
Energy saving in lighting system with fuzzy logic controller which uses light-pipe and dimmable ballast
(Elsevier Science Sa, 2013)Approximately, 20% of the electricity consumed in the world is spent for lighting. More efficient utilization of the sun, as a natural source of light, for lighting would save electricity used for lighting. The aim of this ... -
An investigation into the usability of straight light-pipes in Istanbul
(Sila Science, 2012)With the impact of global warming, recent years has witnessed a tremendous revival of interest in environmental issues. At the moment, the world's electricity generation mainly depends on the fossil fuels which are eventually ... -
Extended q-Dedekind-type Daehee-Changhee sums associated with extended q-Euler polynomials
(Springeropen, 2015)In the present paper, we aim to specify a p-adic continuous function for an odd prime inside a p-adic q-analog of the extended Dedekind-type sums of higher order according to extended q-Euler polynomials (or weighted q-Euler ... -
Determination of Minimum Enzymatic Decolorization Time of Reactive Dye Solution by Spectroscopic & Mathematical Approach
(Office Spectroscopy & Spectral Analysis, 2015)Synthetic dyes are very important for textile dyeing, paper printing, color photography and petroleum products. Traditional methods of dye removal include biodegradation, precipitation, adsorption, chemical degradation, ... -
Early warning systems for currency crises: The Turkish case
(Elsevier, 2012)Different severe financial crises episodes occurred in the Turkish economy in the last two decades. These crises led to severe economic and social consequences for Turkey in terms of increasing interest rates, large reserves ... -
Currency crises in Turkey: An empirical assessment
(Elsevier Science Bv, 2018)Contrary to many previous empirical studies on currency crises, this paper aims to test the relevance of different methodologies and crisis definitions in estimating crisis determinants and predicting crisis episodes in ... -
