Assessment of metal element concentrations in mussel (M. Galloprovincialis) in Eastern Black Sea, Turkey

Çevik, U.; Damla, N.; Kobya, A.I.; Bulut, V.N.; Duran, C.; Dalgic, G.; Bozaci, R. (0-Belirlenecek, 2008)

The main goal of this work is to determine the effects of pollution of copper, lead and zinc mines on the Eastern Black Sea. Metal and heavy metal concentrations in the Eastern Black Sea mussels were measured using Energy ...

Investigation of the dependency of the upper critical magnetic field on the content x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting structures

Çelik, S.; Öztürk, K.; Çevik, U.; Yanmaz, E. (0-Belirlenecek, 2008)

The Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared by using the solid-state reaction technique. Resistivity measurements of the samples were performed in QD-PPMS ...

Determination of radioactivity levels and hazards of soil and sediment samples in Fi{dotless}rti{dotless}na Valley (Rize, Turkey)

Kurnaz, A.; Küçükömeroğlu, B.; Keser, R.; Okumusoglu, N.T.; Korkmaz, F.; Karahan, G.; Çevik, U. (0-Belirlenecek, 2007)

The natural radioactivity levels in soil and sediment samples of Fi{dotless}rti{dotless}na Valley have been determined. To our knowledge, there seems to be no information about radioactivity level in the Fi{dotless}rti{dotless}na ...

Measurement of the mass attenuation coefficients and electron densities for BiPbSrCaCuO superconductor at different energies

Çevik, U.; Baltaş, H. (0-Belirlenecek, 2007)

The mass attenuation coefficients for Bi, Pb, Sr, Ca, Cu metals, Bi2O3, PbO, SrCO3, CaO, CuO compounds and solid-state forms of Bi1.7Pb0.3Sr2Ca2Cu3O10 superconductor were determined at 57.5, 65.2, 77.1, 87.3, 94.6, 122 and ...

Analysis of regional wild-type cereals in Trabzon-Turkey by EDXRF spectrometry

Çevik, U.; Genç, H.; Baltaş, H.; Ertuğral, B. (0-Belirlenecek, 2007)

The energy dispersive X-ray fluorescence (EDXRF) spectroscopy was used to determine essential and trace element contents of some naturally grown wild-type cereals collected in different regions of Trabzon, Turkey. The ...

Investigation of some superconducting properties of ytterbium diffusion-doped YBa2Cu3O7-x superconductors

Öztürk, K.; Çelik, S.; Çevik, U.; Yanmaz, E. (0-Belirlenecek, 2008)

The effect of Yb diffusion on structural evolution and superconducting properties of YBa2Cu307-x (Y123) prepared in the bulk polycrystalline form were studied. The ytterbium (Yb) diffusion in superconducting Y123 ceramic ...

Determination of the effective atomic numbers and electron densities for YBaCuO superconductor in the range 59.5-136 keV

Baltaş, H.; Çevik, U. (0-Belirlenecek, 2008)

The effective atomic numbers and electron densities of YBa2Cu3O7-? superconductor at 59.5, 65.2, 77.1, 94.6, 122 and 136 keV were calculated by using the measured mass attenuation coefficients. Measurements were made by ...

Assesment of trace elements in rainbow trout (Oncorhynchus mykiss) cultured in the marine aquaculture cages on the black sea coast

Verep, B.; Akin, S.; Mutlu, C.; Apaydin, G.; Ertuğral, B.; Çevik, U. (0-Belirlenecek, 2007)

The concentrations of trace elements were determined in various tissues (internal organs, liver, abdominal and dorsal muscle) of individuals of cultured fishes obtained from two marine cage farms located on the coasts of ...
