Electron transport in electrically biased inverse parabolic double-barrier structure
(Iop Publishing Ltd, 2016)
A theoretical study of resonant tunneling is carried out for an inverse parabolic double-barrier structure subjected to an external electric field. Tunneling transmission coefficient and density of states are analyzed by ...
Determination of radioactivity levels of soil samples and the excess of lifetime cancer risk in Rize province, Turkey
(Ijrr-Iranian Journal Radiation Res, 2016)
Background: Turkey, especially the northern part of it, was one of the countries which were contaminated by the Chernobyl accident. Rize is a city located in the Northeastern district of Turkey which was heavily influenced ...
Experimental study on copper uptake capacity in the Mediterranean mussel (Mytilus galloprovincialis)
(Springer Heidelberg, 2016)
To investigate the effect of different sizes, sex, and exposure time on Cu uptake capacity, mussels Mytilus galloprovincialis of different shell sizes were exposed to different Cu concentrations in different aquariums. in ...
Investigation of natural radioactivity and associated radiological hazards in ceramic sanitary ware products commercially sold in Turkey
(Taylor & Francis Ltd, 2019)
All ceramic products used in the construction of buildings contain natural radioisotopes at various rates. These radioisotopes are the main source of outdoor radiation to which people living in houses or workplaces are ...
Determination of natural radionuclides and some metal concentrations in human tooth samples in the Rize province, Turkey
(Taylor & Francis Ltd, 2019)
The main purpose of this study was to identify the concentrations of naturally occurring radionuclides (Ra-226, Th-232 and K-40) and some metals (Fe, Ni, Cu, Zn, Pb and Cd) in tooth samples collected from humans living in ...
Assessment of metal concentrations (Cu, Zn, and Pb) in seawater, sediment and biota samples in the coastal area of Eastern Black Sea, Turkey
(Pergamon-Elsevier Science Ltd, 2017)
This study investigated the contents of Cu, Zn and Pb in seawater, sediment, different shell sizes of mussel (Mytilus galloprovinciaIis) and sea snail (Rapana venosa) samples collected from four different provinces of the ...
Improvement in levitation force performance of bulk MgB2 superconductors through coronene powder adding
(Elsevier Science Sa, 2017)
The effect of coronene (C24H12) addition on the levitation force properties of MgB2 superconductor has been investigated for the first time in this study. the polycrystalline disk-shaped MgB2 + y wt % C24H12 samples (y = ...
The investigation of magnetic levitation performances of single grain YBCO at different temperatures
(Elsevier Science Sa, 2017)
The temperature dependence of the magnetic levitation force has been investigated for single-grain YBCO bulk sample, 20 mm in diameter with a thickness of 8 mm, fabricated by top-seeded melt growth (TSMG) method using Nd123 ...
Determination of radioactivity levels and heavy metal concentrations in seawater, sediment and anchovy (Engraulis encrasicolus) from the Black Sea in Rize, Turkey
(Pergamon-Elsevier Science Ltd, 2017)
Seawater, sediment and fish (anchovy) samples consumed in the Rize province of the Eastern Black Sea region of Turkey were collected from five different stations. the radioactivity levels (Ra-226, Th-232. K-40 and Cs-137) ...
Effect of the Hamiltonian parameters on the hysteresis properties of the kinetic mixed spin (1/2,1) Ising ferrimagnetic model on a hexagonal lattice
(Elsevier Science Bv, 2017)
The hysteresis properties of a kinetic mixed spin (1/2, 1) Ising ferrimagnetic system on a hexagonal lattice are studied by means of the dynamic mean field theory. in the present study, the effects of the nearest-neighbor ...
