Preconcentration and electroanalysis of silver at pt electrode modified with poly(2-aminothiazole)
(Maik Nauka/Interperiodica/Springer, 2013)
Conducting poly(2-aminothiazole) (PAT) films were electrodeposited on a platinum disc electrode surface by constant potential electrolysis of 2-aminothiazole (AT) for the stripping voltammetric determination of Ag(I). Ag(I) ...
Kantrovich Type Generalization of Meyer-Konig and Zeller Operators via Generating Functions
(Ovidius Univ Press, 2013)
In the present paper, we study a Kantorovich type generalization of Meyer-Konig and Zeller type operators via generating functions. Using Korovkin type theorem we first give approximation properties of these operators ...
A fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type
(Charles Babbage Res Ctr, 2013)
In this paper, we prove a fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type. In short, we are going to study mappings A, B,S,T : X -> X for which there exists a ...
Analysis of Phenol in Cigarette Filter Tar Using QuEChERS Sample Preparation and High-Performance Liquid Chromatography/UV Detection System
(Asian Journal Of Chemistry, 2013)
QuEChERS sample preparation was used for determination of phenol in cigarette filter tar. The method involved extraction with acetonitrile followed by solid-phase extraction cleanup with XAD-4 sorbent and the analyse was ...
Korovkin-Type Theorems in Weighted Lp-Spaces via Summation Process
(Hindawi Ltd, 2013)
Korovkin-type theorem which is one of the fundamental methods in approximation theory to describe uniform convergence of any sequence of positive linear operators is discussed on weighted L-p spaces, 1 <= p < infinity for ...
Some new generalizations of Mizoguchi-Takahashi type fixed point theorem
(Springer International Publishing Ag, 2013)
In the light of the paper of Hasanzade Asl et al. (Fixed Point Theory Appl. 2012: 212, 2012, doi:10.1186/1687-1812-2012-212), we obtain a fixed point theorem for multivalued mappings on a complete metric space. Our result ...
Preliminary study on heavy metal concentrations of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Camligoze Dam Lake, Sivas, Turkey
(Bmc, 2013)
The concentrations of heavy metals (Ag, Cd, Co, Cu, Ni, Pb, Zn) were analyzed in muscle, skin and liver of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Camligoze Dam Lake located at Central Anatolian region of ...
Fabrication and characterization of gold-nanoparticles/chitosan film: a scaffold for L929-fibroblasts
(Taylor & Francis Ltd, 2013)
The objective of the present study was to fabricate a gold nanoparticle crosslinked chitosan (Ch/AuNPs) composite film simple and to evaluate its use as a carrier matrix for L929-fibroblasts. L929-fibroblasts were seeded ...
Modification of glassy carbon electrode in basic medium by electrochemical treatment for simultaneous determination of dopamine, ascorbic acid and uric acid
(Elsevier Science Sa, 2013)
In this paper, a modified glassy carbon electrode was prepared by electrochemical method in basic media (0.5 M NaOH solutions) and was used to electrochemically detect dopamine (DA), ascorbic acid (AA), uric acid (UA) and ...
Common fixed point theorems on non-complete partial metric spaces
(Inst Mathematics & Informatics, 2013)
In the peresent paper, we give a common fixed point theorem for four weakly compatible mappings on non-complete partial metric spaces. Some supporting examples are provided.
