, 2015 The volume of air that goes in and out of a musical instrument's sound hole is related to the sound hole's contribution to the volume of the sound. Helmholtz's result for the simplest case of steady flow through an elliptical hole is reviewed. Measurements on multiple holes in sound box geometries and scales relevant to real musical instruments ...

Osong Public Health and Research Perspectives, 2014 Can you remember your old schooldays? For some reason, we remember the old good days as being especially beautiful. All the shrubs on campus were in blossom and the trees were green. The grass was dotted with dandelions. Everyone was happy and carefree, for the vacation was just about to begin. With that to look forward to, no-one was worried about the

Frontiers in Immunology, 2014 THE SILENCE OF HEALTH “Health is life lived in the silence of the organs” wrote the French surgeon Rene Leriche in 1936, a concept later adopted and further developed by the physician and philosopher Georges Canguilhem (1). Albeit certainly resonant with the experience of health defined as the state of well being perceived by an individual, this ...
