For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject deterministic principles classical physics, with gravitational field obeying Newton's law or Einstein's equations. Here we treat a quantum determine implications such treatment for experimental observables. We find that falling bodies in are random fluctuations ("noise"...

The metric determines the casual structure of spacetime, but in quantum gravity it is also a dynamical field which must be quantized using this causal structure; this is the famous problem of time. A radical resolution of this paradox is proposed: remove the concept of space-like separation entirely. This can be done by describing all fields in terms on p-jets, living on the observer’s trajecto...

Solvent separation is frequently applied to petroleum vacuum residues to reduce the coke-forming tendencies of these materials. This process is capable of removing all or a substantial amount of asphaltenes from feedstocks that are destined for further processing and thus applied as the first step of refining. Maltenes and asphaltenes obtained from vacuum residues of Heera (HVR) and Jodhpur (JV...

The Voyager mission to the outer solar system discovered that the thermospheres of all the giant planets are remarkably hot. To date, no convincing explanation for this phenomenon has been offered; however, there are a number of recent observational results which provide new information on the thermal structure of Jupiter's upper atmosphere that bear on this outstanding problem. We present an a...

It has been long recognized that liquids can spread under the action of disjoining pressure. In the case of a liquid attracted to the solid by van der Waals forces, a precursor film is formed, and there is no well-defined contact line that would give rise to the infamous viscous stress singularity. Nevertheless, the problem remains difficult, due to the divergence of both viscous and disjoining...
