Rontgen Rays in Dermatology
r The authors of this book on the value of " Rontgen days !" Dermatology," unfortunately for English readers, Ascribe only the different kinds of German apparatus, instead of giving the type of apparatus employed in a particular case. The section on X-ray dermatitis and the biological effects of X-rays is excellent and is illustrated by coloured plates. The chapters deal with the affections of ...

متن کاملDiffusive Shock Acceleration of High Energy Cosmic Rays
The process of diffusive acceleration of charged particles in shocked plasmas is widely invoked in astrophysics to account for the ubiquitous presence of signatures of non-thermal relativistic electrons and ions in the universe. A key characteristic of this statistical energization mechanism is the absence of a momentum scale; astrophysical systems generally only impose scales at the injection ...
متن کاملInfluence of boundary reflection and refraction on diffusive photon transport.
We report computer simulations which test the accuracy of the diffusion theories used in the analysis of multiple light scattering data. Explicitly including scattering anisotropy and boundary reflections, we find that the predicted probability for transmission through a slab is accurate to 1% if the slab thickness is greater than about 5 transport mean free paths. For strictly isotropic scatte...
متن کاملTurbulent amplification of magnetic field and diffusive shock acceleration of cosmic rays
The diffusive shock acceleration of cosmic rays by supernova remnants depends upon the generation of magnetic fluctuations by cosmic rays upstream of the shock. Strongly driven, non-resonant, nearly purely growing modes grow more rapidly than the resonant Alfvén waves usually considered. Non-linear simulation shows that the magnetic field can be amplified from its seed value by orders of magnit...
