In this paper, the thermodynamic properties of the aqueous mixed electrolyte system containing 1-butyl-3-methylimidazolium chloride ([BMIm]Cl) and NaCl are reported based on the potentiometric method. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type:Ag-AgCl [BMIm]Cl (m1), NaCl(m2), H2O│IL-...
In order to preparing strontium ion selective electrode 6-(4- nitropheny1)-2-pheny14, 4- dipropy1-3, 5-diaza-bicyclo [3, 1, 0] hex-2-ene (NPDBH) was used as an ionophore. This electrode responds to Sr (II)ion with a sensitivity of 28.2 ± 0.5 mV/decade over the range 1.0 x 10-6 to 1.0 Mat pH 3.0-10.0. Thelimit of detection was 2.4 x 10-7 M. The influences of membrane composition, the pH of the t...
The Iranian Light Source Facility (ILSF) project is the first large scale accelerator facility which is currently under planning in Iran. On the basis of the present design, circumference of the 3 GeV storage ring is 528 m. Beam current and natural beam emittance are 400 mA and 0.477 nm.rad, respectively. Some prototype accelerator components such as high power solid state radio frequency ampli...
Subject-specific four-layer boundary element method (BEM) electrical forward head models for four participants, generated from magnetic resonance (MR) head images using NFT (sccn.ucsd.edu/wiki/NFT), were used to simulate electroencephalographic (EEG) scalp potentials at 256 recorded electrode positions produced by single current dipoles of a 3-D grid in brain space. Locations of these dipoles w...
from its emergence till present time marxist principles has undergone great changes since their promulgation by marx. many theorists and thinkers set at rectifying marxist tenets and introducing those of their own while others advocated its main concepts and attempted at improving them. among marxist philosophers who had an intensive study of marxs ideology, is louis althusser whose reflections...
in this study, we explained a nanobiosensor for dna sequence detection, featuring sequence specificity, cost efficiency, speed, and ease of use. without the need for labels or indicators, it may be ideal for the detection of biological agents. this review describes recent advances in electrochemical impedance spectroscopy (eis) with an emphasis on using nanoparticles and nanotechnology. a power...
BACKGROUND There is considerable uncertainty about the time-course of central auditory maturation. On some indices, children appear to have adult-like competence by school age, whereas for other measures development follows a protracted course. METHODOLOGY We studied auditory development using auditory event-related potentials (ERPs) elicited by tones in 105 children on two occasions two year...
We investigate the effect of dipole-dipole and quadrapole- quadrapole interaction of a weakly interacting Bose gas near the transition temperature on the energy spectra of the thermal and condensate parts. We use the two fluid model and mean field approximation. We show that the effects of the condensate part on the shift of energy is greater than the case of contact potential
Abstract The paper presents the latest results of Monte Carlo inversion IP data in areas water base protection and ore exploration. method determining time constant spectrum using parameters characterizing degree environmental contaminations deposition are presented. Among field applications Hungary, investigation ionic pollution Ráckeve characterization Felsőtelekes waste dump Rudabánya iron m...
