Electrochemical reduction of NAP on the glassy carbon electrodes modified with aromatic diazonium salts
(Bentham Science Publ Ltd, 2008)
The electrochemical reduction of 4-{[(1E)-(2-hydroxynaphthyl)methylidene]amino}-1,5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one (NAP) was studied by using cyclic voltammetry in acetonitrile media at a glassy carbon (GC) ...
Adsorption behavior of congo red from an aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 2008)
In this study, a reactive fibrous adsorbent was prepared through the grafting of 4-vinyl pyridine monomer onto poly(ethylene terephthalate) (PET) fibers for the removal of Congo red (CR) dye from an aqueous solution with ...
Preliminary report on surgical mask induced deoxygenation during major surgery
(Soc Espanola Neurocirugia, 2008)
Objectives. This study was undertaken to evaluate whether the surgeons' oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations. Methods. Repeated measures, longitudinal and prospective ...
Comparison of MLP neural network and neuro-fuzzy system in transcranial doppler signals recorded from the cerebral vessels
(Springer, 2008)
Transcranial Doppler signals recorded from cerebral vessels of 110 patients were transferred to a personal computer by using a 16 bit sound card. Spectral analyses of Transcranial Doppler signals were performed for determining ...
The tricriteria flowshop scheduling problem
(Springer London Ltd, 2008)
Multicriteria flowshop scheduling problems have been one of the most attractive subjects in recent years. In the multicriteria flowshop scheduling literature, a very limited number of studies have been performed on problems ...
Banded karyotypes of the Persian squirrel Sciurus anomalus from Turkey
(Firenze Univ Press, 2008)
Karyotypes of seven males and three females of the Persian squirrel, Sciurus anomalus, were analyzed with G- and C-banding techniques and Ag-NOR (nucleolus organizer region) staining. All specimens had the diploid number ...
Effect of homogenization temperature on the martensitic transformation kinetics in a Fe-32%Ni-0.4%Cr alloy
(Elsevier Science Inc, 2008)
Kinetic, morphological and some thermal properties of thermally induced and deformation-induced martensite were studied in a Fe-32%Ni-0.4%Cr alloy. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC) ...
Poly[triaquabis-(μ(2)-3-carboxy-pyrazine-2-carboxyl-ato)dilithium(I)]
(Blackwell Publishing, 2008)
In the title compound, [Li-2(C6H3N2O4)(2)(H2O)(3)](n), the coordination number for both independent Li+ cations is five. One of the Li+ ions has a distorted trigonal-bipyramidal geometry, coordinated by one of the carboxyl ...
Immobilization of glucose isomerase in surface-modified alginate gel beads
(Wiley, 2008)
In this study, glucose isomerase enzyme was entrapped into modified and nonmodified calcium alginate gel beads. Various characteristics of free and immobilized enzymes such as the optimum pH, temperature and dependence of ...
Some fixed point theorems for weakly compatible multi valued mappings satisfying an implicit relation
(Univ Nis, Fac Sci Math, 2008)
In this paper, we prove a common fixed point theorem for multivalued mappings under the condition of weak compatibility. Also, we define compatible maps of type (I) for multivalued mappings and prove a common fixed point ...
