The construction of the space-like surface of constant breadth
(World Scientific Publ Co Pte Ltd, 2019)
The objective of this study is to define an ovaloid surface on the convex closed space-like surfaces of constant breadth when principal curvatures of these surfaces are continuous, non-vanishing functions, and to obtain ...
Dose rates and seasonal variations of U-238, Th-232, Ra-226 K-40 and Cs-137 radionuclides in soils along Thrace, Turkey
(Springer, 2014)
Concentrations of U-238, Th-232, Ra-226, K-40 and Cs-137 are measured in collected soil samples from various locations in the Thrace region of Turkey. The activity concentrations range from 12.82 to 101.75 Bq kg(-1) d.w. ...

First - principles calculations on stability and mechanical properties of various ABO(3) and their alloys
(Elsevier Science Sa, 2018)
In this study, we perform first principle calculations based on density functional theory (DFT) to obtain the ground state structural, elastic and dielectric properties of various ABO(3) type ceramics and their {A(x)A'((1-x))}BO3 ...
Spectroscopic characterization of novel d-amino acid-Schiff bases and their Cr(III) and Ni(II) complexes as antimicrobial agents
(Springer Birkhauser, 2013)
The aim of this work was to investigate the antibacterial and antifungal activities of novel d-amino acid-Schiff bases including fluorine atom and their Cr(III) and Ni(II) complexes. All these substances have been examined ...
Statistically Defining Optimal Conditions of Coagulation Time of Skim Milk

Thin films of peripheral and non-peripheral tetra-substituted copper phthalocyanines [CuPcR4, R =-O(CH2CH2O)(3)CH3 or -S(CH2CH2O)(3)CH3] and their hybrids with single walled carbon nanotubes( SWCNT) have been investigated ...
Solutions of local fractional sine-Gordon equations
(Taylor & Francis Ltd, 2019)
In this paper, we study sine-Gordon equation in order to obtain exact solitary wave solutions in the domain of fractional calculus. By using the definition of conformable fractional derivative, we obtain analytical solutions ...
