Radionuclides and heavy metals concentrations in Turkish market tea
(Elsevier, 2011)
Tea is one of the most popular beverages in the world. The Eastern Black Sea Region of Turkey is one of the main tea producers in Turkey and the fifth in the world. Thus, the chemical components in tea have received great ...
Spectrum analyzer measurement technique for safety evaluation on wireless communication systems
(IEEE, 2011)
In this paper, general information about, unionized radiation, wireless communication systems and electromagnetic fields are given. The safety of mobile phones has been evaluated in terms of specific absorption ratio (SAR). ...
Preparation and characterization of new window material CdS thin films at low substrate temperature (<300 K) with vacuum deposition
(Elsevier, 2011)
Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare new window material CdS thin films. The structural, optical and electrical properties ...
Radionuclide concentration in tea, cabbage, orange, kiwi and soil and lifetime cancer risk due to gamma radioactivity in Rize, Turkey
(Wiley, 2011)
BACKGROUND: In this study, the activity concentrations of 232Th, 238U, 40K and 137Cs were measured in tea, cabbage, orange, kiwi and soil samples collected from different stations using gamma spectrometry with a high-purity ...
Fuzzy logic controlled buck-boost DC-DC converter for solar energy-battery system
(IEEE, 2011)
In this paper, a Fuzzy Logic Controlled (FLC) buck-boost DC-DC converter for solar energy-battery systems is presented. General design of a fuzzy logic controller (FLC), based on Matlab/Simulink is performed. This design ...
Study of microwave surface resistance of type-II superconductors carrying transport current
(Wiley, 2011)
We investigate the microwave surface resistance of an infinitely long type-II superconductor in the critical state carrying transport DC current, in the absence and in the presence of external magnetic fields. Calculations ...
Structural and optical properties of ZnO thin films by the spin coating Sol-Gel method
(Kluwer Academic Publishers, 2011)
ZnO thin films were deposited onto glass subsrates by a Sol-gel spin coating method. The structural and optical properties of ZnO thin films were investigated. The molar ratios of the zinc acetate dihydrate to Monoethanolamine ...
Sipping tests for the irradiated fuel elements of the TR-2 research reactor
(Carl Hanser Verlag, 2011)
Sipping tests have been performed for fuel elements of the TR-2 reactor at Çekmece Nuclear Research and Training Center (CNRTC), in order to find out which one failed in the core. A sipping assembly has been constructed ...
Heavy metal analysis around Murgul (Artvin) copper mining area of Turkey using moss and soil
(Elsevier, 2012)
This research investigates heavy metal pollution around one of the most important mining areas in Turkey, the Murgul mining, by means of analyzing moss and soil samples collected in the neighborhood of the copper mining ...
Radioactivity and heavy metal concentrations in food samples from Rize, Turkey
(Wiley, 2012)
BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident in 1986. A comprehensive study was planned and carried out to determine the radioactivity levels and heavy metal concentrations in four food categories ...
