School Happiness: A Scale Development and Implementation Study
(2019)
Purpose: This research aimed to determine schoolhappiness level of the teachers based on their opinions. For this purpose, ‘School Happiness Scale’ was developed by the researchers. The validity and reliability of the ...
Structural Analysis Model and Teaching Evaluation (Modelling of Open Source Exam Application and Student Opinions)
(2019)
The aim of this research is to seek an answer for the questions of how open source exam application which includes three years practice data for structural analysis of information structures and practical reality; the ...
On the variational curves due to the ED-frame field in Euclidean 4-space
(2020)
In this study, we define a variational field for constructing a family of Frenet curves of the length l lying on aconnected oriented hypersurface and calculate the length of the variational curves due to the ED-frame field ...
Preparation and characterization of mesoporous activated carbons from waste watermelon rind by using the chemical activation method with zinc chloride
(Elsevier, 2019)
Waste watermelon rind was analyzed as a precursor for preparing activated carbons by using a one-step chemical activation process by zinc chloride. The effects of activation parameters, i.e., carbonization temperature, ...
Synthesis of Isoxazolopyridines and Spirooxindoles under Ultrasonic Irradiation and Evaluation of Their Antioxidant Activity
(Hindawi Ltd, 2017)
New polycyclic-fused isoxazolo[4,5-e] pyridines and spirooxindoles were obtained via multicomponent reaction of 5-amino-3-methylisoxazole, indan-1,3-dione, and aromatic aldehydes and reaction of 5-amino-3-methylisoxazole, ...
Trace metal and radionuclide pollution in marine sediments of the Aegean Sea (Izmir Bay and Didim)
(Springer, 2013)
To determine radioactivity and trace metal levels, surface sediments were collected from two important areas (A degrees zmir Bay and Didim) in the Aegean Sea region of Turkey, and were analyzed for concentrations of Po-210, ...
Characterization of an AlN buffer layer and a thick-GaN layer grown on sapphire substrate by MOCVD
(Springer, 2011)
An AlN buffer layer and a thick-GaN layer for high-electron-mobility transistors (HEMTs) were grown on sapphire substrate by metal-organic chemical vapor deposition (MOCVD). The structural and morphological properties of ...
Effects of high-temperature AIN buffer on the microstructure of AlGaN/GaN HEMTs
(Pleiades Publishing Inc, 2013)
Effects on AlGaN/GaN high-electron-mobility transistor structure of a high-temperature AlN buffer on sapphire substrate have been studied by high-resolution x-ray diffraction and atomic force microscopy techniques. The ...
(+)-CSA Catalyzed Multicomponent Synthesis of 1-[(1,3-Thiazol-2-ylamino)methyl]-2-naphthols and Their Ring-Closure Reaction under Ultrasonic Irradiation
(Hindawi Ltd, 2016)
New 1-[(1,3-thiazol-2-ylamino)methyl]-2-naphthols were obtained by condensation of 2-aminothiazole, aromatic aldehydes, and 2-naphthol in the presence of (+)-camphor-10-sulfonic acid ((+)-CSA) as an effective catalyst under ...
Integral inequalities of Hermite-Hadamard type for exponentially subadditive functions
(Amer Inst Mathematical Sciences-Aims, 2020)
In this paper, we introduce a new class of functions, which is called exponentially subadditive functions. We establish Hermite-Hadamard inequalities via exponentially subadditive functions. We also give some related ...
