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

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) ...
SENSITIVE DETERMINATION OF 3,4-DIHYDROXY-L-PHENYLALANINE BY A CLOUD FUNNEL MUSHROOM (Clitocybe nebularis (Batsch), P. Kumm.) HOMOGENATE-BASED AMPEROMETRIC BIOSENSOR
(Trakya Univ Balkan Yerlesesi Enstituler Binasi, 2021)
3,4-dihydroxy-L-phenylalanine (L-DOPA) is one of the precursor molecules for the biosynthesis of neurotransmitters in the brain. Monitoring of L-DOPA levels as a drug or biomolecule in biological fluids is crucial for the ...
