Geochemical and isotopic characteristics of stream and terrace sediments of the Harsit Stream, NE Turkey
(Geological Soc Publ House, 2017)
The current study compares and contrasts the elemental concentrations and the Nd, Sr and O isotopic compositions of sediments collected from the Harsit Stream bed sediments (HSBS) and terrace sediments (HSTS). There are ...
Synthesis, characterization and thermal behaviour of novel phthalocyanines bearing chalcone groups on peripheral positions
(Bulgarian Acad Science, 2015)
A new nickel, zinc, cobalt, copper and metal-free phthalocyanine was synthesized by nucleophilic aromatic substitution reaction of (E)-3-(3-hydroxyphenyl)-1-phenylprop-2-en-1-one with 4-nitrophthalonitrile and cyclotetramerisation ...
Betting on the Future: A Comparison Macroeconomic Dynamics of Labour Income Share in The United States: Evidence From MARS
(Adapt Univ Press, 2020)
Macroeconomic dynamics of the labour income share (herein: lis) in the United States for the period of 1948Q1-2019Q1 are tried to be determined in this study, where the Multivariate Adaptive Regression Splines (will be ...
BLUE STAIN IN LUMBER INDUSTRY AND LOSSES CAUSED BY CUTTING METHODS
(Slovak Forest Products Research Inst, 2020)
In this study, it is aimed to determine the waste and productivity losses of Scots pine (Pinus sylvestris L.) logs that were exposed to blue stain degradation. In this context, a total of 39 timber production processes ...
Synthesis and Determination of Some Biological Activities of Novel 2,4-Dinitrophenyl Derivatives
(Wiley-V C H Verlag Gmbh, 2015)
The antioxidant and radical scavenging activities of the synthesized compounds 3, 5, and 6 were determined by various in vitro assays such as 2,2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid radical (ABTS(+)) scavenging, ...
Mineralogical and Chemical Characteristics of Clay Areas, Gumushane Region (NE Turkey), and Their Detection Using the Crosta Technique with Landsat 7 and 8 Images
(Springer, 2021)
The clay areas in Gumushane (NE Turkey) were examined in mineralogical and geochemical terms, and by remote sensing methods. X-ray diffraction, scanning electron microscope and chemical analysis were completed on samples ...
Design of a MATLAB GUI for Day Ahead Forecasting of PV Panel Power
(IEEE, 2019)
This paper introduces design and utilization of a MATLAB graphical user interface (GUI) platform to forecast day ahead hourly Photovoltaic (PV) panel power by using forecasted day ahead global horizontal solar radiation. ...
A novel OTA-based circuit model corroborated by an experimental semiconductor memristor
(Elsevier Science Bv, 2018)
A semiconductor memristor device based on a 300-nm ZnO thin film was fabricated by direct-current reactive sputter. The memristive behavior of this device was confirmed by time dependent current-voltage (I-V-t) measurements, ...
Stability estimates for solution of IBVP to fractional parabolic differential and difference equations
(Amer Inst Physics, 2016)
In this work, we investigate initial-boundary value problems for fractional parabolic equations with the Neumann boundary condition. Stability estimates for the solution of this problem are established. Difference schemes ...
Multiobjective optimization of laminated composite cylindrical shells for maximum frequency and buckling load
(Elsevier Sci Ltd, 2009)
This paper deals with multiobjective optimization of laminated cylindrical shells to maximize a weighted sum of the frequency and buckling load under external load. The layer fibre orientation is used as the design variable ...
