Adsorption behaviour of methylene blue from aqueous solution on poly(ethylene terephthalate)-g-4-vinylpyridine/2-hydroxyethylmethacrylate fibers
(Walter De Gruyter Gmbh, 2007)In this study, a novel fibrous adsorbent obtained by grafting 4-vinyl pyridine (4-VP)/2-hydroxyethylmethacrylate ( HEMA) comonomers onto poly ( ethylene terephthalate) ( PET) fibers was used for removal of methylene blue ... -
C-heterochromatin and NORs distribution in karyotypes of three vespertilionid bat species from Turkey
(Walter De Gruyter Gmbh, 2015)The chromosomal banding analysis of the karyotypes of Turkish populations of Eptesicus serotinus, Nyctalus lasiopterus and Barbastellus barbastellus was performed with the use of C-banding and Ag-NOR staining. The results ... -
Controlled release of indomethacin from crosslinked alginate beads
(Walter De Gruyter Gmbh, 2008)Beads of the sodium alginate ( NaAlg) were prepared by dropping aqueous sodium alginate ( NaAlg) into glutaraldehyde ( GA) as a crosslinker and HCl as a catalyst mixture solution. Beads prepared were used to deliver a model ... -

Differences in structure, allergenic protein content and pectate lyase enzyme activity of some Cupressaceae pollen
(Walter De Gruyter Gmbh, 2018)Objective: Cupressaceae pollen has commonly been reported to be an important aeroallergen and causal factor of spring, autumn and winter pollinosis in many countries. The aim of this study was to compare of the structure ... -
Expression of antimicrobial peptides in recurrent adenotonsillitis
(Walter De Gruyter Gmbh, 2016)Background: Recurrent acute tonsillitis is one of the most frequent otorhinolaryngology clinic referrals, yet its pathogenesis remains poorly understood. Antimicrobial cationic peptides are components of the innate system. ... -
The Finite-Size Scaling Study of the Specific Heat and the Binder Parameter of the Two-Dimensional Ising Model for the Fractals Obtained by Using the Model of Diffusion-Limited Aggregation
(Walter De Gruyter Gmbh, 2009)The two-dimensional Ising model with nearest-neighbour pair interactions is simulated oil the Creutz cellular automaton by using the finite-size lattices with the linear dimensions L = 80, 120, 160, and 200. The temperature ... -
Generalized Baskakov type operators
(Walter De Gruyter Gmbh, 2017)In this paper, we introduce a generalization of Baskakov operators based on a function rho. We prove a weighted Korovkin type theorem and compute the rate of convergence via weighted modulus of continuity for these operators. ... -
Generalized q-Baskakov operators
(Walter De Gruyter Gmbh, 2011)In the present paper we propose a generalization of the Baskakov operators, based on q integers. We also estimate the rate of convergence in the weighted norm. In the last section, we study some shape preserving properties ... -
On Approximation Properties of a New Type of Bernstein-Durrmeyer Operators
(Walter De Gruyter Gmbh, 2015)The present paper deals with a new type of Bernstein-Durrmeyer operators on mobile interval. First, we represent the operators in terms of hypergeometric series. We also establish local and global approximation results for ... -
On Fibonomial Sums Identities With Special Sign Functions: Analytically Q-Calculus Approach
(Walter De Gruyter Gmbh, 2018)Recently Marques and Trojovsky [On some new identities for the Fibonomial coefficients, Math. Slovaca 64 (2014), 809-818] presented interesting two sum identities including the Fibonomial coefficients and Fibonacci numbers. ... -
On the modification of the Szasz-Durrmeyer operators
(Walter De Gruyter Gmbh, 2016)In this paper we consider the modification of Szasz-Durrmeyer operators based on the Jain basis function. Voronovskaya-type estimates of point-wise convergence along with its quantitative version based on the weighted ... -
