Korovkin type approximation theorems in weighted spaces via power series method
(Element D.O.O., 2018)
In this paper we consider power series method which is also member of the class of all continuous summability methods. We study a Korovkin type approximation theorem for a sequence of positive linear operators acting from ...
Synthesis, characterisation and DFT calculations of azo-imine dyes
(Turkish Chemical Society, 2018)
In this study, azo dyes containing an imine group were synthesised by coupling p-hydroxybenzylidene aniline with the diazonium salts of p-toluidine, 4-aminophenol, aniline, p-chloroaniline, p-fluoroaniline and p-nitroaniline. ...
Nicotinamide-modified poly(HEMA-GMA)-Nic cryogels for removal of pesticides
(Turkish Chemical Society, 2018)
Chlordane is only one of the persistent pesticides used in some countries despite the ban. Removal of chlordane, a severe threat to all living things, was performed using nicotinamide-modified poly (2-hydroxyethyl ...
Nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole derivatives: Synthesis of pyrrolopyrazinone, pyrrolotriazinone, and pyrrolooxazinone moieties
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2017)
Intramolecular nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole esters is described. Efficient routes towards the synthesis of pyrrolopyrazinone, pyrrolotriazinone and pyrrolooxazinone have been ...
A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
(Nature Publishing Groups, 2018)
Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ...
The legal foundations of the commercial relations between the Ottomans and Neapolitans
(Ahmet Yesevi University, 2014)
Having gained the ahdname, ahdname-i hümâyûn or capitulation, a European nation was permitted to establish an embassy in Istanbul and consulates in the ports of the Ottoman Empire. In 1740, the Kingdom of the Two Sicilies ...
A note on the generalized Matsumoto relation
(TUBİTAK, 2017)
We give an elementary proof of a relation, first discovered in its full generality by Korkmaz, in the mapping class group of a closed orientable surface. Our proof uses only the well-known relations between Dehn twists. © TÜBİTAK.
First order self-adjoint multipoint quasi-differential operators
(TÜBİTAK, 2018)
In this paper, using the Calkin-Gorbachuk method, the general form of all self-adjoint operators generated by first order linear singular multipoint quasi-differential expressions in the direct sum of weighted Hilbert ...
Some results on uniform statistical cluster points
(TUBİTAK, 2017)
In this paper, we present some results linking the uniform statistical limit superior and inferior, almost convergence and uniform statistical convergence of a sequence. We also study the relationship between the set of ...
Some results concerning the summability of spliced sequences
(TUBİTAK, 2016)
A spliced sequence is formed by combining all of the terms of two or more convergent sequences, in their original order, into a new spliced sequence. In this paper replacing convergent sequences by bounded sequences, we ...
