Semi-empirical model for Henry's law constant of noble gases in molten salts.

Henry's law constant, which describes the proportionality of dissolved gas to partial pressure of free gas in liquid-gas equilibrium systems, can also be applied to mass transport applications. In this work, we investigated an approach for determining the solubility of noble gases in a molten salt liquid utilizing the equilibrium concept of Henry's gas constant. Henry's gas constant is described as a mathematical function dependent on the van der Waals radius of the noble gas and the temperature of the molten salt.

Molecular dynamics simulation for PBR pebble tracking simulation via a random walk approach using Monte Carlo simulation.

Using a Monte Carlo (MC) simulation, random walks were used for pebble tracking in a two-dimensional geometry in the presence of a biased gravity field. We investigated the effect of viscosity damping in the presence of random Gaussian fluctuations. The particle tracks were generated by Molecular Dynamics (MD) simulation for a Pebble Bed Reactor.

EuroQol and survival prediction in terminal cancer patients: a multicenter prospective study in hospice-palliative care units.

Goals Of Work: Although the EuroQol (EQ-5D) is widely used for economic evaluation, it remains unclear whether it can be combined with medical data to predict survival in patients with terminal cancer.

Patients And Methods: We carried out this prospective study on 142 terminal cancer patients in four hospice-palliative care units. Association was sought between survival time and a range of variables such as cancer site, performance, previous treatment, age, sex, pain, and EuroQol.
