Laboratory experiments play an important role in improving the modelling of rock avalanches since they contribute to a better understanding of the mechanisms that characterise propagation and to identifying parameters influencing velocity and deposit chara ...
It is widely accepted that metabolic rates scale across species approximately as the 3/4 power of mass in most if not all groups of organisms. Metabolic demand per unit mass thus decreases as body mass increases. Metabolic rates reflect both the ability of ...
We report experimental results related to the dam-break problem for viscoplastic fluids. Using image processing techniques, we were able to accurately reconstruct the free-surface evolution of fixed volumes of fluid suddenly released a plane. We used Carbo ...
We report a measurement of the exclusive e+e-→Λc+Λc- cross section as a function of center-of-mass energy near the Λc+Λc- threshold. A clear peak with a significance of 8.2σ is observed in the Λc+Λc- invariant mass distribution just above threshold. With a ...
