Metastability in drowning-out crystallisation: precipitation of highly soluble sulphates

Crystallisation of a highly metastable hydrated calcium pyrophosphate phase

Metastability, nucleation, and noise-enhanced stabilization out of equilibrium.

We study metastability and nucleation in a kinetic two-dimensional Ising model that is driven out of equilibrium by a small random perturbation of the usual dynamics at temperature T. We show that, at a mesoscopic/cluster level, a nonequilibrium potential describes in a simple way metastable states and their decay. We thus predict noise-enhanced stability of the metastable phase and resonant pr...

Serum Level of Soluble CD226 Receptor in Healthy Individuals is Highly Variable and Associated with Age

Pediatric near-drowning and drowning.

Childhood water submersion remains a major public health problem. The aim of this article is to present an updated overview of the topic with data from our region and special attention to prevention strategies. Children less than 5 years and males are particularly at risk. Infants are at higher risk of drowning in bathtubs, toilets, or washing machines, while most drowning in older children occ...

Immersion, near-drowning and drowning.

“Drowning” is defined as “suffocation by submersion, especially in water”66; it continues to be the third most common cause of accidental death in the general population and, for children in many countries, the second most common cause after road accidents.75 In the USA, 40% of drowning victims are less than 4 yr old.74 In Britain, the Office of Population Census reports that child deaths from ...
