In summary: As a material is heated, it increases in temperature until it enters a phase transition. During the transition, added heat does not increase the temperature. As this heat is being added, what is the substance? Is it a mixture of liquid and gas perhaps? If so, what ...
Numerical modeling of phase change requires accurate estimations of heat and mass transport at the interface. The present work develops a model in ANSYS-Fluent with user-defined functions to address phase change with a planar interface. An interface boundary method determines the heat fluxes with the...
When the boundary condition causing a phase change is interrupted, the phase change process continues until the temperature distribution in the whole system becomes uniform due to the temperature gradients existing in both phases. This continuing phase change during the so called stand-by solidification...

As a natural record of the climate change, phenopheses can objectively reflect temperature changes. Because the phenophases during 1888～1916 was generally later than nowadays, it can be inferred that the climate during 1888～1916 was colder than the present day. The average spring temperature ...
the past 2,000 years using a globally distributed compilation of proxies for δprecip, δMWand δSW. We show that global mean surface temperature exerted a coherent influence on global δprecipand δMWthroughout the past two millennia, driven by global ocean evaporation and condensation processes...
The cell cycle in amoebae of Dictyostelium discoideum has been analysed in cells growing asynchronously in axenic medium. For cells growing at the optimum growth temperature of 22 degrees C with a culture doubling time of 8 h the average times for the cell cycle phases are as follows: G1, ...
The control pulse is applied before the pressure rises due to the presence of fast combustion, allowing ignition to be detected during the inflammation phase, thus allowing the possibility to place additional ignition events, if necessary. This technique was experimentally analyzed in a Constant ...
