This is a comment on a paper by Greaves, Rodriguez, and Ruiz-Camacho [Am. J. Phys. 77, 894 (2009)] which reports a measurement of the one-way speed of light., Comment: 1 page, LaTex, no figures

Aharonov and Reznik have recently (in quant-ph/0110093) argued that the form of the probabilistic predictions of quantum theory can be seen to follow from properties of macroscopic systems. An error in their argument is identified., Comment: LaTeX, 6 pages, no figures

Cabello has recently (in quant-ph/0210081) observed that ``...an EPR-experiment with a fixed POVM on each particle provides a violation of Bell's inequality without requiring local observers to choose between the alternatives.'' In this note I discuss the implications of this observation for tests of locality., Comment: LaTeX, 3 pages, no figures

Widom, Srivastava, and Sassaroli have published [Phys. Lett. A 203, 255 (1995)] a calculation which purports to show that "future events can affect present events". In this note an error in their calculation is identified., Comment: 3 pages, LaTeX, no figures

There is a great need to provide effective, on-going education and monitoring for the large numbers of asthmatic patients, in particular for those who have a history of aggravating asthma. The complex asthma self management and the busy modern lifestyles makes it unlikely that patients without outside help and support can effectively follow their self-care plans on a regular basis. This study, evaluated the impact of an asthma self-care support system, delivered by telecommunications and computer technology, which has the potential of making a significant contribution in the management of asthma. Analysis of 40 patients using the system showed a significant improvement in the asthma symptoms, lung function test, adherence to action plan and overall decrease in the use of quick relief inhaler.

In radiation of the thorax, the lung has been shown to be a major dose-limiting organ. The early and late responses of the lung to radiation has been reviewed, with primary emphasis on the following cell types: type II pneumocyte, type I pneumocyte, pulmonary endothelial cell and macrophage. The earliest observable and quantifiable cellular response to radiation is exhibited by the type II pneumocytes as a decrease in lamellar bodies and a corresponding increase in surfactant content of the alveolar lavage. By 18-63 weeks following exposure, several type II cells, restored in their lamellar body population, undergo degeneration and sloughing into alveolar spaces. Type I pneumocytes generally exhibit little change, although some investigators describe alveolar denudation due to degenerating type I cells. Macrophages decrease in numbers following irradiation, returning to normal populations by 4 weeks. These changes correspond closely to the changes in alveolar lavage phospholipid phosphorus. Descriptions of radiation-induced damage to endothelial cells are variable. However, blebbing and vacuolation appear to be late developing responses, although altered permeability may be earlier in its expression. Radiation pneumonitis and fibrosis are the two major clinical and experimental responses of the lung to radiation following exposures of greater than 12 Gy. The former appears to involve type II cells, macrophages and pulmonary endothelial cells, and for the latter macrophages, fibroblasts, type II pneumocytes and the pulmonary endothelial cells are involved. The two events are not interdependent, and may not necessarily be interrelated.
