Superconductivity in Bismuth. A New Look at an Old Problem

To investigate the relationship between atomic topology, vibrational and electronic properties and superconductivity of bismuth, a 216-atom amorphous structure (a-Bi216) was computer-generated using our undermelt-quench approach. Its pair distribution function compares well with experiment. The calculated electronic and vibrational densities of states (eDOS and vDOS, respectively) show that the...

Hyperuricemia; a new look at an old problem

*Corresponding author: Prof. Mahmoud Rafieian-Kopaei, Medical Plants Research Center, Shahrekord University of Medical Sciences, Sharekord, Iran. E-mail: [email protected] Recently much attention had been directed toward the significance of hyperuricemia in general population and aggravation of nephropathy. Various investigations have shown that elevated uric acid levels might have a deleterio...

Preference Reversal: a New Look at an Old Problem

A generalized weak dominance approach is used to test the documented preference reversal (PR) phenomenon. This approach simply models risky choice behavior in PR as a choice between the best possible outcomes or a choice between the worst possible outcomes by equating smaller paired outcome difference between bets. The preference reversals are therefore seen as a consequence of the fact that ga...

Renal tubular acidosis: a new look at an old problem.

Although the definition of renal tubular acidosis (RTA) is simple, understanding the physiologic basis underlying the various types of this clinical entity is much more difficult. The pathophysiology of this disorder is reviewed using the normal acid-base functions of the involved segments of the nephron as a guide to understanding. Clinical and laboratory features of the subtypes of RTA are ad...
