The main objective of this paper is, in terms of LCA (life cycle assessment), to compile and discuss, environmental impacts of aircraft, gas turbine engine and components, and maintenance process and operations in the ...
Health risk assessment of trace elements in medicinal plants consumed as medicine and food in Rize, Turkey
(Parlar Scientific Publications (P S P), 2020)
Trace element (Cd, Pb, Ni, Fe, Zn, Cu, Cr, Co and Mn) levels were measured using Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) in twelve different medicinal plants consumed as medicine and food in Rize, ...
Local structure displacements in La1-xCex OBiSSe as a function of Ce substitution
(Pergamon-Elsevier Science Ltd, 2020)
We have investigated the local structure of layered La1-xCexOBiSSe system by Bi L-3 -edge extended X-ray absorption fine structure (EXAFS) measurements for different Ce substitutions. Ce L-3-edge X-ray absorption spectroscopy ...
The effect of solid boriding time on the structure, hardness and corrosion properties of AISI 5140 steel
(Maik Nauka/Interperiodica/Springer, 2020)
In this study, AISI 5140 steel samples were borided in an electrical furnace at a temperature of 950 degrees C for 4, 6 and 8 h. Structural examinations, hardness measurement and corrosion tests were performed to determine ...
Radioactivity in Kosovo honey samples
(Hard, 2020)
The aim of this study was to determine naturally occurring radionuclides (K-40, Ra-226 and Th-232) and the artificial radionuclide Cs-137 in various honey samples from Kosovo. This study is of particular importance because ...
Enthesitis and its relationship with disease activity, functional status, and quality of life in psoriatic arthritis: a multi-center study
(Springer Heidelberg, 2020)
Psoriatic arthritis (PsA) is an inflammatory arthritis with distinct phenotypic subtypes. Enthesitis is assigned as a hallmark of the disease, given its significant relations to disease activity and quality of life. Our ...
Microstructural, mechanical and tribological properties of ultrafine-grained Cu-Cr-Zr alloy processed by high pressure torsion
(Elsevier Science Sa, 2020)
The effect of temperature on tribological properties of coarse grained (CG) and ultrafine-grained (UFG) Cu-Cr-Zr alloy processed via high pressure torsion (HPT) was investigated. Dominant wear mechanism depends on both ...
