Separation and preconcentration of lead, chromium and copper by using with the combination coprecipitation-flame atomic absorption spectrometric determination
(Elsevier Science Inc, 2014)
A coprecipitation method was developed for the quantitative separation and preconcentration of Pb(II), Cr(III) and Cu(II) ions. Analytes were coprecipitated using a triazole derivative (2-{4-[2-(1H-indol-3-yl)ethyl]-3-(4 ...
Oxidation of cyanobenzocycloheptatrienes: Synthesis, photooxygenation reaction and carbonic anhydrase isoenzymes inhibition properties of some new benzotropone derivatives
(Pergamon-Elsevier Science Ltd, 2014)
The oxidation of some cyanocycloheptatrienes with CrO3 and pyridine was investigated and a few new nitrile functionalised benzotropone derivatives were obtained. Photooxygenation reaction of these products was also studied. ...
Attitudes Toward Ethically Questionable Negotiation Tactics: A Two-Country Study
(Springer, 2014)
Current research has identified five discrete US negotiation tactics, a traditional one considered to be ethical, and four considered to be ethically questionable. Scholars have independently used culture to explain how ...
Backfill and subsoil interaction effects on seismic behavior of a cantilever wall
(Techno-Press, 2014)
The main focus of the current study is to evaluate the dynamic behavior of a cantilever retaining wall considering backfill and soil/foundation interaction effects. For this purpose, a three-dimensional finite element model ...
A new 5,6-dihydro-2-pyrone derivative from Phomopsis amygdali, an endophytic fungus isolated from hazelnut (Corylus avellana)
(Elsevier, 2014)
Aims of this study were to isolate endophytes from different parts of hazelnut - Corylus avellana L. to obtain bioactive secondary metabolites and search for the presence of gene region of taxadiene synthase (Ts), a key ...
The petrogenesis of Early Eocene non-adakitic volcanism in NE Turkey: Constraints on the geodynamic implications
(Elsevier Science Bv, 2014)
Whole-rock geochemistry, mineral chemistry, the Ar-40-Ar-39 age, and Sr-Nd isotopic data are presented for the Early Eocene non-adakitic volcanic rocks on the eastern corner of the Eastern Pontides orogenic belt (NE Turkey). ...
High order of accuracy difference schemes for the inverse elliptic problem with Dirichlet condition
(Springer International Publishing Ag, 2014)
The overdetermination problem for elliptic differential equation with Dirichlet boundary condition is considered. The third and fourth orders of accuracy stable difference schemes for the solution of this inverse problem ...
Preparation of a New Sorbent, Cetyltrimethylammonium Bromide (CTAB)-Modified Obsidian, for the Separation and Preconcentration of Pb(II) and Cd(II) Ions in Food and Water Samples
(Atomic Spectroscopy Press Ltd, 2014)
Cetyltrimethylammonium bromide (CTAB)-modified obsidian (CTAB-OB) was utilized as a new sorbent for the separation and preconcentration of Pb(II) and Cd(II) ions by solid phase extraction in some environmental samples prior ...
The Arabidopsis thaliana FASCICLIN LIKE ARABINOGALACTAN PROTEIN 4 gene acts synergistically with abscisic acid signalling to control root growth
(Oxford Univ Press, 2014)
Background and Aims The putative FASCICLIN-LIKE ARABINOGALACTAN PROTEIN 4 (At-FLA4) locus of Arabidopsis thaliana has previously been shown to be required for the normal growth of wild-type roots in response to moderately ...
ASSESSMENT OF KINETICS, THERMODYNAMICS AND EQUILIBRIUM PARAMETERS OF CR(VI) BIOSORPTION ONTO Pinus brutia TEN
(Wiley, 2014)
The aim of the present study was to investigate the sorption potential of pine bark (Pinus brutia Ten.) for removal of Cr(VI) ions from aqueous solutions. The biosorption characteristics of Cr(VI) ions onto bark biomass ...
