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 ...
Determination of hypertension disease using chirp z-transform and statistical features of optimal band-pass filtered short-time photoplethysmography signals
(Iop Publishing Ltd, 2020)
Hypertension is the condition where the normal blood pressure is high. This situation is manifested by the high pressure of the blood in the vein towards the vessel wall. Hypertension mostly affects the brain, kidneys, ...
Use of the cold substrate method for biomaterials: the dtructural and biological properties of the Ag layers deposited on Ti-6Al-4V
(Springer, 2020)
Silver nanofilms were vacuum-deposited on Ti-6Al-4V substrates at low (< 300 K) temperatures to improve their biocompatibility. After the surface of the Ti-6Al-4V samples was coated with Ag over the temperature range from ...
The comparison of levitation and lateral force of bulk and cut-pasted bulk GdBCO samples at different temperatures
(Elsevier Science Sa, 2020)
In this work, in the first time, we have investigated the levitation and lateral force properties of bulk and cut-pasted bulk GdBCO samples at different temperatures and different cooling heights (CH) to determine the ...
A reactor antineutrino detector based on hexagonal scintillator bars
(Elsevier, 2020)
This study presents a new concept of segmented antineutrino detector based on hexagonal plastic scintillator bars for detecting antineutrinos from a nuclear reactor core. the choice of hexagonal scintillator bars is original ...
Cold substrate method to prepare plasmonic Ag nanoparticle: deposition, characterization, application in solar cell
(Springer Heidelberg, 2020)
In this study, the surface plasmon effects of the Ag nanoparticle were investigated depending on the substrate temperature and coating time. Deposition procedure for the Ag coating was the vacuum deposition at low substrate ...
