The question how much surplus of electric charge ("surcharge") fits on an object is generally very difficult to answer. Here it shown that easy answer when the a \emph{failed white dwarf} star (a brown dwarf in its ground state) made protons and electrons: Given number protons, many electrons can there be? Surprisingly, (in form: as few $\mathfrak{A}$ $\mathfrak{B}$) independent speed light $c$...

The European sovereign debt crisis has impaired many European banks. The distress on the European banks may transmit worldwide, and result in a large-scale knock-on default of financial institutions. This study presents a computer simulation model to analyze the risk of insolvency of banks and the consequent knock-on defaults in a bank credit network. Simulation experiments quantify the worst i...

The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...

La surcharge des services d’urgences est un problème rencontré par les systèmes de santé à l’échelle mondiale . En Suisse, plus 80% sont concernés cette problématique. Les grands consommateurs (GCSU) contribuent [2]. Le recours fréquent aux urgences souvent lié au cumul difficultés somatiques, psychologiques et sociales, fréquentes chez GCSU.
