Birinci Türkiye Büyük Millet Meclisi’nin Adalet Vekillerinden Ahmet Rifat (Çalıka) Bey ve Faaliyetleri
(2021)
Yakın tarihimizde önemli roller oynamış fakat sonrasında unutulup neredeyse kimsenin hatırlamadığı bazı simalar vardır. Ahmet Rifat (Çalıka) Bey de bunlardan biridir. 1914’te daha yirmi yedi yaşındayken Kayseri Belediye ...
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 ...
A NOTE ON SPRAYS OF ISOTROPIC CURVATURE
(Editura Bibliotheca-Bibliotheca Publ House, 2021)
A basic goal of this paper is to calculate, Weyl curvature of R-flat (Ricci-flat) spray of isotropic curvature and a locally projectively R-flat (Ricci-flat) spray, which is a projective invariance. Besides, the equivalents ...
alpha-Amination and the 5-exo-trig cyclization reaction of sulfur-containing Schiff bases with N-phenyltriazolinedione and their anti-lipid peroxidation activity
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2017)
Triazolinedione quenches efficiently the 1,2-dipoles from Schiff bases of glycine esters which are formed via a [1,2-H]-prototropic shift of their alpha-hydrogens, and affords the respective alpha-aminated products in good ...
