Magneto optical properties and hperfine interactions of Cr3+ Ion substituted copper ferrite nanoparticles
(Springer New York LLC, 2018)
Spinel CuCrxFe2−xO4 (0.0 ≤ y ≤ 1.0) nanoparticles were fabricated by co-precipitation. X-ray diffraction proved the pureness and cubic crystal assembly of products which have the crystallite sizes varying between 16 and ...
Structural, optical and mössbauer study of Ba1 − xCuxFe12O19 (0.5 ≤ x) nano hexaferrites
(Springer New York LLC, 2018)
In this study, a novel Ba1−xCuxFe12O19 (0.5 ≤ x) nano-hexaferrites were prepared by a simple and cost-effective sol–gel auto-combustion method using barium nitrates, iron nitrate, copper (II) acetate monohydrate and citric ...
Synthesis and characterization of Cu–Mn substituted SrFe12O19 hexaferrites
(Springer New York LLC, 2018)
In this study, bimetallic (Cu–Mn) substituted SrFe12O19 hexaferrites [Sr1−2xMnxCuxFe12O19 (0.0 ≤ x ≤ 0.1)] were synthesized via sol–gel auto-combustion approach. The effect of bimetallic substitution on structure, morphology ...
Investigation of geriatric patients with abdominal pain admitted to emergency department
(Hindawi Limited, 2018)
Introduction. The aim of this study is to detect the possible reasons of abdominal pain in the patients aged 65 and older admitted to emergency department (ED) with complaint of abdominal pain which is not related to trauma, ...
Environmental education at faculty of agriculture and changing awareness, attitude and behavior towards environment in Turkey
(Tarbiat Modares University, 2018)
Environmental problems have become increasingly more destructive. For this reason, environmental education and awareness have gained importance. This study had two objectives: to determine the factors affecting the attitude ...
High grade urothelial carcinoma of renal pelvis presenting as spontaneous urinoma
(2018)
Perirenal urine extravasation, also known as urinoma, occurs usually after renal trauma. Spontaneous urinoma is a very rare pathology in daily urology practice. The patients with spontaneous urinoma usually present with ...
Exploring guideline adaptation strategy for Turkey: Is “ADAPTE” feasible or does it need adaptation as well?
(Blackwell Publishing Ltd, 2018)
Rationale, aims, objectives: Clinical Practice Guidelines are mostly developed by 3 methods; namely, de novo, adoption, and adaptation. Nonpublished studies and authors experience shows that most guidelines in Turkey are ...
Study on thermoluminescence of TlInS2 layered crystals doped with Pr
(Elsevier Ltd, 2018)
Praseodymium (Pr) doped TlInS2 crystals were studied by means of thermoluminescence (TL) measurements performed below room temperature with various heating rates. Detected TL signal exhibited glow curve consisting in ...
Important biomarkers that play a role in the chronic obstructive pulmonary disease process
(Society of Medical Biochemists of Serbia and Montenegro, 2018)
Background: Chronic obstructive pulmonary disease (COPD) that includes multiple mechanisms such as inflammation, infection, smoking, hypoxia, and lack of antioxidant response can cause oxidative stress. In our study, we ...
Effect of annealing temperature on magnetic and mössbauer properties of ZnFe2O4 nanoparticles by sol-gel approach
(Springer New York LLC, 2018)
In this study, spinel ZnFe 2 O 4 nanoparticles (NPs) were synthesized by citrate sol-gel route using nickel nitrates, ferric nitrates and citric acid by annealing at 900, 1000, and 1100 ? C. We reported the structural and ...
