Annual effective dose and concentration levels of gross α and β in various waters from Samsun, Turkey
(Elsevier, 2011)
Samsun city which is between the deltas where YeŞilirmak and Kizilirmak rivers run out, exists in the middle part of Black Sea's costal way. It is the biggest city of the Black Sea Region in terms of population, industry, ...
Determination of mass attenuation coefficients for natural minerals from different places of Turkey
(2011)
The mass attenuation coefficients (?m) for some natural minerals taken from different places of Turkey were measured at various low photon energies. The Am-241 radioactive source and Zr and Cd secondary exciter are used ...
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 ...
Molecular integrals over slater-type orbitals. From pioneers to recent developments
(Nova Science Publishers, Inc., 2011)
It can readily be demonstrated that atomic and molecular orbitalsmust decay exponentially at long-range. They should also possess cusps when two particles approach each other. Therefore, Slater orbitals are the natural ...
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 ...
Effect of CdCl2/annealing on the crystalline transformation of CdTe thin films grown by evaporation at a low substrate temperature
(TÜBİTAK, 2011)
The structural and optical properties of CdTe thin films prepared at a low substrate temperature were investigated before and after the CdCl 2/annealing. The crystal structure of CdTe film was cubic with a strong (111) ...
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 ...
