On the system of double equations with three unknowns d
(Semnan Univ, 2021)
The system of double equations with three unknowns given by d + ay + bx + cx(2) = z(2), y + z = x(2) is analysed for its infinitely many non-zero distinct integer solutions. Different sets of integer solutions have been ...
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. ...
On the real quadratic fields with certain continued fraction expansions and fundamental units
(Semnan Univ, 2017)
The purpose of this paper is to investigate the real quadratic number fields Q(root d) which contain the specific form of the continued fractions expansions of integral basis element where d equivalent to 2, 3(mod4) is a ...
Determination of the effects of initial glucose on the production of alpha-amylase from Penicillium sp under solid-state and submerged fermentation
(Taylor & Francis Ltd, 2014)
The effects of catabolite repression of initial glucose on the synthesis of alpha-amylase from Penicillium chrysogenum and Penicillium griseofulvum were investigated under solid-state fermentation (SSF) and submerged ...
Sparse polynomial interpolation with Bernstein polynomials
(Scientific Technical Research Council Turkey-Tubitak, 2021)
We present an algorithm for interpolating an unknown univariate polynomial f that has a t sparse representation (t << deg(f) ) using Bernstein polynomials as term basis from 2t evaluations. Our method is based on manipulating ...
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 ...
Analytical exact solutions for the Razavy type potential
(Wiley, 2020)
A quantum system with Razavy type potential which transforms to single or double well potential according to negative or positive potential parameterk, is solved analytically by using extended form of Nikiforov-Uvarov (NU) ...
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 ...
On computing the degree of a Chebyshev Polynomial from its value
(Academic Press Ltd- Elsevier Science Ltd, 2021)
Algorithms for interpolating a polynomial f from its evaluation points whose running time depends on the sparsity to f the polynomial when it is represented as a linear combination of t Chebyshev Polynomials of the First ...
