The dynamical solar atmosphere
Journal of Physics: Conference Series, 2010 High resolution space and ground-based telescopes made it clear that one of the most fundamental characteristics of solar atmosphere is that it is dynamic, showing stationary and non-stationary motion on all time and space scales. Dynamical changes in the solar atmosphere are rather difficult to interpret given the presence of the magnetic field and ...

Influence of the spatial distribution of gravity wave activity on the middle atmospheric dynamics
, 2016 . Analysing GPS radio occultation density profiles, we have recently pointed out a localised area of enhanced gravity wave (GW) activity and breaking in the lower stratosphere of the east Asian–northwestern Pacific (EA/NP) region.

Advanced Engineering Materials, EarlyView.Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

The importance of northern peatlands in global carbon systems during the Holocene [PDF]
, 2009 We applied an inverse model to simulate global carbon (C) cycle dynamics during the Holocene period using atmospheric carbon dioxide (CO2) concentrations reconstructed from Antarctic ice cores and prescribed C accumulation rates of Northern Peatlands (NP)

Advanced Engineering Materials, EarlyView.A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Orbital atmospheric physics and dynamics [PDF]
There are two ways of modeling the upper atmosphere. One is the empirical model that makes use of experimental data on means and excursions from the mean and fits the data in a self-consistent manner.
