(Elsevier Science Bv, 2015)
The aim of this research was to investigate the effect of the several nanomaterials in electrochemical determination of Cu(II) ions. For this aim, firstly the deposition of graphene oxide (GO), graphene, magnetite (Fe3O4), ...
Due Date Single Machine Scheduling Problems with Nonlinear Deterioration and Learning Effects and Past Sequence Dependent Setup Times
(Hindawi Ltd, 2014)
We present some problems against due dates with nonlinear learning and deterioration effects and past sequence dependent setup times. In this study, two effects (learning and deterioration) are used for the same processing ...
An Artificial Neural Networks Approach to Estimate Occupational Accident: A National Perspective for Turkey
(Hindawi Ltd, 2014)
Occupational accident estimation models were developed by using artificial neural networks (ANNs) for Turkey. Using these models the number of occupational accidents and death and permanent incapacity numbers resulting ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Springer, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
Development of poly(3-aminophenylboronic acid) modified graphite rod electrode suitable for fluoride determination
(Elsevier Science Bv, 2014)
Poly(3-aminophenylboronic acid), (PAPBA) film was formed on the graphite rod surface by potential cycling. The PAPBA-modified graphite rod (PAPBA/GR) electrode prepared in this way was used for potentiometric fluoride ...
Composition of the Essential Oil of Some Centaurea L.
