Whilst intense solar flares are almost always accompanied by a coronal mass ejection (CME), reports on stellar CMEs rare, despite the frequent detection of 'super flares'. The torus instability magnetic flux ropes is believed to be one main driving mechanisms CMEs. Suppression instability, due confining background field that decreases sufficiently slowly with height, may contribute lack CME det...
This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...
We prove some consistency results about b(λ) and d(λ), which are natural generalisations of the cardinal invariants of the continuum b and d. We also define invariants bcl(λ) and dcl(λ), and prove that almost always b(λ) = bcl(λ) and d(λ) = dcl(λ)
The French government has committed to launch the satellite TARANIS to study transient coupling processes between the Earth’s atmo sphere and near-Earth space. The prime objective of TARANIS is to detect energetic charged particles and hard radiation emanating from thunderclouds. The British Nobel prize winner C.T.R. Wilson predicted lightning discharges from the top of thunderclouds into spac...
An overview on the present observational status and phenomenological understanding of cosmic rays above 10 eV is given. Above these energies the cosmic ray flux is expected to be gradually dominated by an extra-galactic component. In order to investigate the nature of this transition, current experimental activities focus on the measurement of the cosmic ray flux and composition at the ’ankle’ ...
345 “A Letter to my Younger Colleagues” is a series of essays written by selected senior Canadian paediatricians, who were named as outstanding mentors by a prominent group of their younger peers. I hope you enjoy and treasure the rich pearls of wisdom that each author offers, based on a lifetime of professional practice and personal reflections. Andrew Lynk MD Assistant Editor, Paediatrics & C...
Grasslands comprise natural tropical savannah over managed temperate fields to tundra and cover one quarter of the Earth's land surface. Plant growth, maintenance and decay result in volatile organic compound (VOCs) emissions to the atmosphere. Furthermore, biogenic VOCs (BVOCs) are emitted as a consequence of various environmental stresses including cutting and drying during harvesting. Fluxes...
A unique parameterization of the QCD equation of state below and above T c We present a unique parameterization of the equation of state of strongly interacting matter in the temperature interval 0.6T c · · · 3T c at µ = 0 within a quasi-particle model based on quark and gluon degrees of freedom. The extension to non-vanishing baryon-chemical potential is discussed.
