Evaluation of a surface equation of state generally involves an evaluation of its ability to represent raw experimental data, or information derived from such data, after the parameters of the equation have been adjusted to optimize this representation, followed by an evaluation of the physical reasonableness of the optimizing parameters in terms of the physical model on which the equation of s...

We describe a general strategy, PERM (Pruned-Enriched Rosenbluth Method), for sampling configurations from a given Gibbs-Boltzmann distribution. The method is not based on the Metropolis concept of establishing a Markov process whose stationary state is the wanted distribution. Instead, it starts off building instances according to a biased distribution, but corrects for this by cloning “good” ...

The efficiency of polyfunctional monomers as cross-linking co-agents on the chemical properties of natural rubber vulcanized by electron beam irradiation was studied. The following polyfunctional monomers were used: trimethylolpropane-trimethacrylate, zinc-diacrylate, ethylene glycol dimethacrylate, triallylcyanurate and triallylisocyanurate. The electron beam treatment was done using irradiati...

Grave and complicated pollution problems are posed by the existence of heavy metals trendy environment this has been a focus study all over world. The Activated carbonized avocado pear seed (ACAPS) activated orange peel (ACOP) were each soaked with potassium hydroxide (KOH) solution at 1:1 ratio, for 48 hours, outcome was washed, air-dried separately oven dried 105℃ 6 hours further heated in mu...

effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. lungmuir, frumkin and flory-huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

The detection of genetically modified (GM) materials in food and feed products is a complex multi-step analytical process invoking screening, identification, and often quantification of the genetically modified organisms (GMO) present in a sample. "Combinatory qPCR SYBRGreen screening" (CoSYPS) is a matrix-based approach for determining the presence of GM plant materials in products. The CoSYPS...

The Flory–Huggins (FH) isotherm first appeared in the literature of water contaminant adsorption mid-2000s. It has come into limelight and received considerable attention recent years, large part due to regular coverage review articles. Here, we point out that a linear form FH is incompatible with original nonlinear version. We show conclusively was destroyed beyond recognition by linearization...
