The Evaluation Potential as Micronized Calcite of White Marble Waste
(Polish Mineral Eng Soc, 2020)
Natural calcium carbonates have a great importance in the world's economy due to their numerous applications areas such as calcium carbonate in the paper and paint industries. The final calcite products have rigorous quality ...
The Effects of Moisture Content and Coal Mixtures on the Grinding Behavior of Two Different Coals
(Taylor & Francis Inc, 2014)
In this article, effects of moisture content and coal mixtures on grinding properties of the samples of two different fine coals, which were used in the Golta Cement Factory in Isparta (Turkey) were investigated. Grinding ...
Magnetic properties, anticancer and antibacterial effectiveness of sonochemically produced Ce3+/Dy3+ co-activated Mn-Zn nanospinel ferrites
(Elsevier, 2020)
Some new types of Ce3+ and Dy3+ co-doped manganese-zinc nanospinel ferrites (CDMZNSFs) of the form (Mn0.5Zn0.5)[Fe2-2xCexDyx]O-4 (with 0.0 <= x <= 0.1) were sonochemically produced and characterized. The structure, morphology, ...
Influence of Dy3+ Ions on the Microstructures and Magnetic, Electrical, and Microwave Properties of [Ni0.4Cu0.2Zn0.4](Fe2-xDyx)O-4 (0.00 <= x <= 0.04) Spinel Ferrites
(Amer Chemical Soc, 2021)
[Ni0.4Cu0.2Zn0.4](Fe2-xDyx)O-4 spinel ferrite nanoparticles with different Dy3+ concentrations (0.00 <= x <= 0.04) were prepared by a citrate sol-gel auto-combustion technique. A strong correlation among Dy concentration, ...
Structural, Magnetic, and Mossbauer Parameters' Evaluation of Sonochemically Synthesized Rare Earth Er3+ and Y3+ Ions-Substituted Manganese-Zinc Nanospinel Ferrites
(Amer Chemical Soc, 2021)
The effect of Er3+ and Y3+ ion-co-substituted Mn0.5Zn0.5ErxYxFe2-2xO4 (MZErYF) (x <= 0.10) spinel nanoferrites (SNFs) prepared by a sonochemical approach was investigated. Surface and phase analyses were carried out using ...

(Sage Publications Inc, 2021)
Objective This study evaluated the effect of low-energy radiofrequency thermocoagulation added to standard liquid sclerotherapy on clinical outcomes of patients with venous insufficiency. Patients and method We included ...
Role of Gal-3 and H-FABP in the early diagnosis of acute coronary syndrome
(Comenius University, 2019)
OBJECTIVES: We aimed to compare the plasma levels of biomarkers such as: serum Gal-3, H-FABP, cTnI, and CK-MB in patients, who were admitted to the emergency room with chest pain, and to determine whether these biomarkers ...
Carotid artery stenosis in asymptomatic patients undergoing coronary artery bypass grafting: who and when should be screened?
(Polskie Towarzystowo Kardiologiczne, 2021)
BACKGROUND Carotid artery stenosis (CAS) is one of the major causes of stroke in coronary artery bypass grafting (CABG). AIMS The aim of this study was to determine which age groups require screening for CAS using carotid ...
Application of multiple linear regression (MLR) analysis for concentration of chromite tailings by the flotation
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2020)
In this study, the concentration of chromite minerals by amine flotation of a chromite tailing (slime) with content 23.84% Cr2O3 from Yesilova-Burdur (Turkey) was investigated. In experimental studies, firstly, some operating ...
Evaluation of Grindability Behaviors of Four Different Solid Fuels Blending by Using the Hardgrove Mill
(Polish Mineral Eng Soc, 2019)
Grindability measurements are widely used in mineral and coal processing industry to determine resistance of materials to comminution. Grindability measurement as testing methods can be divided into two general categories; ...
