genetic programming (gp) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. the genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. in this paper the systems containing amino acids ...
In this work, the results relating to the mean activity coefficient measurements for ionic liquid of 1- propyl -3 methylimidazolium bromide, [PMIm]Br in ethanol+ water mixtures have been reported using potentiometric measurements at T=( 298.2, 308.2 and 318.2)K. The electromotive force (emf) measurements were performed on the galvanic cell of the type:Br-ISE│[PrMIm] (m) ethanol (wt.%), H2O (1−w...
potentiometric investigation on {h2o+nano3+peg1500} mixtures were made at t=308.15k, using electrochemical cells with two ion-selective electrodes, (na+ glass) as the cation ion-selective electrode against (no3- solvent-polymer pvc) as the anion ion-selective electrode. the mean ionic activity coefficients of nano3 were measured at different concentrations of nano3 and peg. maximum concentrati...

Using the Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubilitiesof Li2CO3 were determined in various mixed- solvent "water + ethanol" with various mass percentof ethanol, and in the presence of NaNO3 in various molarities at 25.0°C . The results wereinterpreted in terms of mean ionic activity coefficient and ion association phenomenon.
Potentiometric investigation on {H2O+NaNO3+PEG1500} mixtures were made at T=308.15K, using electrochemical cells with two ion-selective electrodes, (Na+ glass) as the cation ion-selective electrode against (NO3- solvent-polymer PVC) as the anion ion-selective electrode. The mean ionic activity coefficients of NaNO3 were measu...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
In this work, an equation of state has been utilized for thermodynamic modeling of aqueous electrolyte solutions. The proposed equation of state is a combination of simplified statistical associating fluid theory (SAFT) equation of state (similar to simplified PC-SAFT) to describe the effect of short-range interactions and mean spherical approximation (MSA) term to describe the effect of long-r...
