Mechanisms of cast structure and stressed state formation in Hadfield steel [PDF]
China Foundry, 2016 The paper describes the investigation of mechanisms of cast structure formation in Hadfield steel depending on the changes in the cooling rate of a casting in the following two temperature ranges: crystallization temperature (1,200-1,390 °С) and the ...

Simulations of Jet Heating in Galaxy Clusters: Successes and Challenges
, 2018 We study how jets driven by active galactic nuclei influence the cooling flow in Perseus-like galaxy cluster cores with idealised, non-relativistic, hydrodynamical simulations performed with the Eulerian code ATHENA using high-resolution Godunov methods ...

Theory of cavity-assisted microwave cooling of polar molecules [PDF]
, 2008 We analyze cavity-assisted cooling schemes for polar molecules in the microwave domain, where molecules are excited on a rotational transition and energy is dissipated via strong interactions with a lossy stripline cavity, as recently proposed by A ...

Laser Cooling of two trapped ions: Sideband cooling beyond the Lamb-Dicke limit [PDF]
, 1998 We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogously to sideband cooling of a single ion.

Nature's diffusion experiment: The cooling-rate cooling-age correlation
Geology, 2000 Correlation between the age of orogeny and the cooling rate of metamorphic rocks (through ∼500–180 °C), as determined through various radioisotopic dating methods, suggests that ancient orogens cooled at rates as much as two orders of magnitude slower than those of active orogens.

Magneto-thermal condensation modes including the effects of charged dust particles [PDF]
, 2009 We study thermal instability in a magnetized and partially ionized plasma with charged dust particles. Our linear analysis shows that the growth rate of the unstable modes in the presence of dust particles strongly depends on the ratio of the cooling ...

Absolute Cooling Rates of Freely Decaying Fullerenes [PDF]
Physical Review Letters, 2009 The cooling rates of C60- have been measured in an electrostatic storage ring between several hundred mus and several tens of ms with one-photon laser excitation. The absolute energy scale is established by the photon energy, and the cooling time interval is derived from the nonexponential decay of the ensemble of hot molecules.
