a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion w...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
We have studied the laser spectra from conjugated chalcone in a few organic solutions. The laser of the chalcone appears to arise from its monomeric state. Chalcone in solutions of acetone or tetrahydrofuran (THF) was pumped by the third harmonics of an Nd: YAG (355 nm) for different concentrations and pump-pulse energies.
KEYWORDS Load ow analysis, numerical techniques. ABSTRACT A number of facts about quadratic power ow problems f(x) = y + g(x) = 0, x 2 R n x , y 2 R n y and applied Newton-Raphson methods with optimal multipliers are presented. The main results are about solution structure, singular points and Newton-Raphson solutions. Comments and discussions are given. Although we address here to the power ow...
The present study conducted a preliminary examination of the psychometric properties of a recently developed Portuguese translation of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005). A total of 311 Brazilian adults completed the ACSS along with Portuguese translations of measures of actual-ideal body weight discrepancy, body appreciation, sociocultural at...
BACKGROUND Even though itch is a common syndrome of many diseases there is only little knowledge about sex and gender differences in pruritus, especially in central itch perception and modulation. To our knowledge, this is the first fMRI study examining sex differences in perception and its modulation by distraction. METHODS Experimental itch was induced by application of histamine (0.1 mM) v...
