We analyze plane strain deformations of a representative volume element (RVE) to evaluate effective thermophysical parameters of a particulate composite comprised of two perfectly bonded heat conducting elasto-thermo-visco-plastic constituents. It is assumed that the composite is also isotropic and its response elasto-thermo-visco-plastic. Effective values of material parameters so computed are...

This study presents a comparative computational examination of different cubic equations state (EoS) on hydrate inhibition fluid systems involving real reservoir fluids. Two gas inhibitors (Monoethylene glycol – MEG and methanol) were considered alongside 4 EoS namely; Cubic-Plus-Association (CPA) coupled with Infochem mixing rules, Soave-Redlich-Kwong (SRK) the Huron-Vidal (HV) rule, Peng Robi...

In this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (LNG) mixtures. In one approach, 12 cubic equations of state (EoSs), comprising the popular Peng-Robinson (PR) and Redlich-Kwong-Soave (RKS), are employed to predict the saturated liquid density of 20 LNG mixtures. In the other approach, these EoS are used in conjunction with a rec...

During the past two decades, mass spectrometry has become established as the primary method for protein identification from complex mixtures of biological origin. This is largely attributable to the fortunate coincidence of instrumental advances that allow routine analysis of minute amounts (typically femtomoles) of involatile, polar compounds such as peptides in complex mixtures, with the rapi...

If the selection of an adequate prior was the major conceptual and modeling challenge of Bayesian analysis, the major implementational challenge is computation. As soon as the model deviates from the conjugate structure, finding the posterior (first the marginal) distribution and the Bayes rule is all but simple. A closed form solution is more an exception than the rule, and even for such close...

Application of cavity ring down (CRD) spectrometry for measuring the optical properties of pure and mixed laboratory-generated aerosols is presented. The extinction coefficient (α ext), extinction cross section (σ ext) and extinction efficiency (Q ext) were measured for polystyrene spheres (PSS), ammonium sulphate ((NH 4) 2 (SO 4)), sodium 5 chloride (NaCl), glutaric acid (GA), and Rhodamine-59...

A thermodynamic modeling for the vapor–liquid equilibrium of binary systems of supercritical fluids and ionic liquids is presented. The van der Waals mixing rules and a cubic equation of state are used to evaluate the fugacity coefficient on the systems. Then, a particle swarm algorithm was used to minimize the difference between calculated and experimental bubble pressure, and calculate the in...

this paper reviews the relationship between the rule of law, good governance, and sustainable development as those terms are used by the relevant development organizations; describes the efforts made by various organizations to promote the rule of law and good governance; and addresses the need to strengthen compliance and enforcement for sustainable development. a recent movement, which has re...
