Purpose The most significant application of polychlorinated biphenyls (PCBs) is in transformers and capacitors. Therefore, power plants are important suspected sources for entry of PCBs into the environment. In this context, the levels and distribution of PCBs in sediment, soil, ash, and sludge samples were investigated around Seyitomer thermal power plant, Kutahya, Turkey. Moreover, identity and contribution of PCB mixtures were predicted using the chemical mass balance (CMB) receptor model.

An ab initio study on ethylenedinitramine and its monovalent ions
Türker, Burhan Lemi (Elsevier BV, 2005-02-14)
An explosive material, ethylenedinitramine (EDNA), its mono and di aci forms, as well as its monovalent cation and anion forms have been considered for 6-31G (UHF) type ab initio quantum chemical treatment in order to investigate the stability of EDNA in the neutral form and when charges develop on it exposed to electrical fields during the storage, handling or explosion process. The calculations indicate stable species. The aci forms are less stable than EDNA itself and the anion form is more stable than t...
Quantum chemical treatment of cyanogen azide and its univalent and divalent ionic forms
Türker, Burhan Lemi; Atalar, Taner (Elsevier BV, 2008-05-30)
An explosive material, cyanogen azide (CN4) and its univalent and divalent anionic and cationic forms have been studied quantum chemically by using different theoretical approaches. In this study, the structures considered have been screened for their relative stabilities. Also, they have been investigated whether the charged forms play a role in the usual explosion process or any electrical charging during storage cause explosion. Various quantum chemical properties are obtained and discussed. It has been ...
A theoretical study on vomitoxin and its tautomers
Türker, Burhan Lemi; Guemues, Selcuk (Elsevier BV, 2009-04-15)
In the present work, the structural and electronic properties of vomitoxin (deoxynivalenol, a mycotoxin) and all of its possible tautomers have been investigated by the application of B3LYP/6-31 G(d,p) type quantum chemical calculations. According to the results of the calculations, tautomer V-4 has been found to be the most stable one among all the structures both in the gas and aqueous phases. The calculations also indicated that, vomitoxin and V-2 possess the deepest and the highest lying HOMO levels, re...
Comparison of two glutathione S-transferases used in capacitive biosensors for detection of heavy metals
Saatci, Ebru; Nistor, Mihaela; Gaspar, Szilveszter; Csoregi, Elisabeth; İşcan, Mesude (Informa UK Limited, 2007-01-01)
This work describes the development of a heavy-metal biosensor based on either recombinant 6His-Tag glutathione S-transferase (GST-(His)(6)) or glutathione S-transferase Theta 2-2 (GST-theta 2-2), and a capacitive transducer. The dynamic range of the pure bovine liver GST-Theta 2-2 biosensor was 1 fM to 1mM for Zn2+, and 10pM to 1mM for Cd2+. The GST-(His) 6 biosensor was able to detect Zn2+ and Cd2+ in the range of 1 fM to 10 mu M, and Hg2+ in the range of 1 fM to 10mM. The bovine liver GST Theta 2-2 biose...
A Detailed Power Loss Analysis of Modular Multilevel Converter
Erturk, Feyzullah; Hava, Ahmet Masum (2015-03-19)
This paper thoroughly examines the semiconductor power loss characteristics of modular multilevel converters (MMC). Power loss behavior is examined under different pulse width modulation (PWM) methods and operating conditions. The effects of stored energy level, circulating current control utilization, power factor and submodule voltage balancing method on power loss are studied. Furthermore, unbalanced power losses and specific semiconductor stresses within a submodule are visualized by investigating the l...
