Dynamic magnetic features of a mixed ferro-ferrimagnetic ternary alloy in the form of ABpC1−p
(Springer Heidelberg, 2021)
In this work, we studied the dynamic magnetic features of a mixed ferro-ferrimagnetic ternary alloy in the form of AB(p)C(1-p). We also investigated the effect of Hamiltonian parameters on the system's dynamic magnetic ...
Assessing pollution levels and health effects of heavy metals in sediments around Cayeli copper mine area, Rize, Turkey
(Bellwether Publishing, Ltd., 2021)
Heavy metal concentrations of Mn, Cr, Fe, Ni, Cu, Zn, Cd and Pb in sediment samples collected from 12 stations in the Black Sea coast, Buyukdere and Sabuncular streams around Cayeli copper mine area in Rize, Turkey were ...
Beam dynamic studies at accelerator system of gun for a self-amplified spontaneous emission free electron laser project
(Elsevier, 2021)
One of the important factors in high radiation generation facilities is the production of a high quality electron beam. To do that, the requirements of an optical electron source, such as current, radiation emission, etc. ...
Evaluation of ecological risk, source, and spatial distribution of some heavy metals in marine sediments in the Middle and Eastern Black Sea region, Turkey
(Springer Heidelberg, 2021)
In the present study, the concentration levels of heavy metals such as Mn, Fe, Ni, Cu, Zn, Cr, and Pb in sediment samples collected from 16 sampling locations in the Middle and Eastern Black Sea regions, Turkey, were ...
Polarization effects on intersubband absorption in GaN/ZnGeN2 quantum wells
(Igdir University, 2021)
The effects of spontaneous and piezoelectric polarizations on the intersubband absorption in the GaN/ZnGeN2 quantum well are studied. Schrödinger and Poisson equations are solved self-consistently. The first order linear ...
Determination of heavy metal levels in some moss samples collected from near the highways in Burdur province
(Çankırı Karatekin Üniversitesi, 2021)
The main sources of atmospheric heavy metals deposition are agricultural activities, fossil fuels, central heating
stations and the exhaust gases of motor vehicles. In this study, the total of 29 mosses samples were ...
The radiation shielding properties of the low temperature alloys
(Afyon Kocatepe University, 2021)
Solder alloys are significant for many applications. In addition to the physical electrical and magnetic
properties of solders, it is of great importance to determine the shielding properties of the materials in
order ...
Hierarchical clustering of selected countries according to the variables of population, national income and exports of goods and services
(2021)
The changes in the population, gross domestic product (GDP) and exports of goods and services of the 32 countries
that we have selected for 25 years have annually been examined. In this study, we use hierarchical ...
Improved performance of CdS powder-based hybrid solar cells through surface modification
(Gümüşhane Üniversitesi, 2021)
The effects of surface modification of CdS through organic Eosin-Y, indoline D205, and Ru-based complex N719 and
N3 dyes on CdS-based hybrid solar cells were studied. Chemical bath deposition (CBD) and doctor blade methods ...
On the 30th anniversary of the Chernobyl Nuclear Power Plant Accident, assessment of the activity concentrations and the radiological hazard parameters of soil samples collected from Rize province and districts
(Elsevier Ltd, 2021)
Uranium, thorium and potassium are the main terrestrial sources of radiation that are located at different levels in the soil depending on the geographical and geological conditions and contribute to increase of the natural ...
