متن کاملGrain boundary melting in ice.
We describe an optical scattering study of grain boundary premelting in water ice. Ubiquitous long ranged attractive polarization forces act to suppress grain boundary melting whereas repulsive forces originating in screened Coulomb interactions and classical colligative effects enhance it. The liquid enhancing effects can be manipulated by adding dopant ions to the system. For all measured gra...
متن کاملMelting of ice under pressure.
The melting of ice under pressure is investigated with a series of first-principles molecular dynamics simulations. In particular, a two-phase approach is used to determine the melting temperature of the ice-VII phase in the range of 10-50 GPa. Our computed melting temperatures are consistent with existing diamond anvil cell experiments. We find that for pressures between 10 and 40 GPa, ice mel...
متن کاملSimulation of ice-sheet melting
A simple model is presented where the temperature, extent and thickness of sea ice is predicted in a numerical simulation. The model is based on Newton’s law of cooling with added terms to account for black-body emission by the ice and solar and atmospheric radiation. The ice is assumed to be an ellipsoid, with the temperature being uniform throughout. Coupled equations are developed for the te...
متن کاملSuicide warning signs in clinical practice.
This review discusses suicide warning signs in clinical practice and has three simple goals: 1) to help practitioners differentiate in a clinically meaningful fashion between warning signs and risk factors for suicide; 2) to articulate the link among warning signs for suicide, hopelessness, and intent to die; and 3) to assist practitioners in applying warning signs in day-to-day clinical practi...
