... High-pressures experiments are mostly aimed at studying phase transformations in solids, synthesising new phases and studying their composition, crystal and magnetic structure, physical and thermodynamical properties. ... The specific feature of investigations at LHPP that distinguishes it from most other high-pressure laboratories is combining in situ measurements with studies at ambient pressure of new high-pressure phases fixed by quenching to liquid nitrogen temperature. ...

... Star formation requires interstellar clouds that are cold and dense enough for self-gravity to overcome internal pressure from gas thermal motions and other factors, thus leading to cloud contraction and eventual collapse to stellar densities. ... Absorption has all of these parameters plus one more describing the fraction of the emission (p) that is behind the absorbing cloud. ... Obser ving Interstellar Hydrogen Clouds Clouds in the ISM can produce either emission or absorption spectra. ...

... The properties of the dust grains (e.g., temperature and mass) can be derived from fitting far-IR SEDs (т??100 ЮМm). Only with SPIRE on Herschel has it been possible to get high spatial resolution at 200 to 500 ЮМm that is beyond the peak (~160 ЮМm) of dust emission in most galaxies. Aims: We investigate the differences in the fitted dust temperatures and masses determined using only 200 ЮМm data is for deriving these dust properties. ...

... A consistent theory of turbulence has not been constructed as yet (this problem is linked with one of the one million dollar problems of the Clay Mathematics Institute), and therefore researchers all over the world rely on computer simulations to understand the underlying physics and processes in star forming environments. As computer power grows our simulations become more and more realistic, allowing us to include a lot of interesting and potentially vital physics into our models.  ...

... Determining the nominal roll angle for stable intervals . ... We found the necessary information in a file 'rh*.ao', which has a binary extension table for each obi. ... Unlike the question of determining the nominal roll angle, we know of no a priori indication of this problem (although the guide star configuration may be the cause, or at least associated with this condition): it is necessary to examine the source position for each obi. ... The guide star record is at the end of the 'anc file'. ...

... When creating a mosaic from a set of individual frames, the correct background offset for each frame must be determined for proper matching. In this paper we describe a method for constructing a mosaic from a set of individual frames by applying a minimization technique. ... Typically these are frames with some known defect (see ? ... Determining which frames to exclude from the final mosaic is critical, since one bad frame can create background offset errors that propagate throughout the mosaic. ...
