E100 CMAJ, January 10, 2012, 184(1) © 2012 Canadian Medical Association or its licensors When students asked the celebrated Sir William Osler about the role of the physician of the day, he is quoted as saying “diagnosis, diagnosis and diagnosis.” Consistent with this, 80% of the 67 original articles in Volume 1 of the Canadian Medical Association Journal related to the description and diagnosis...

“It is undoubtedly the final frontier of cataract and refractive surgery.There is great interest and excitement in this field of research at the moment and we are seeing some very interesting approaches coming on stream which hold great promise for future treatment of presbyopia,” said David Spalton FRCS, FRCOphth, who co-chaired the symposium. Dr Spalton said it was important to remember that ...

The concept of chiral symmetry has been of great importance in elementary-particle physics for many years. ' ' In the context of massless quarks and quantum chromodynamics it is, of course, an exact symmetry, and should survive the proof of confinement in some way. It is not surprising, therefore, that immediately after the presentation of the original MIT bag model4 Chodos and Thorn' attempted...

A determination of the A0 and A1 cavity modes (here called collectively ”air modes”) in the violin has been made using CO2, helium and air/helium mixtures. The use of a “glove bag” enabled the atmosphere surrounding the violin to be better controlled than relying on the difference in density to displace the air inside the instrument. The cavity modes in CO2 and He were moved to frequencies as p...

The aim of our study was to identify which support conditions result in producing the best accuracy with a bolt action, large calibre firearm, even over long distances. Precision is feature that shows how closely impact points are grouped relative each other. According Litz, precision primarily determined by non-deterministic coefficients. He also states choice right equipment aimed at reducing...
