An experienced marathon runner died suddenly during a competitive race. At necropsy, ventricular hypertrophy but no asymmetrical septal hypertrophy was found. Histological studies showed features of hypertrophic cardiomyopathy. The coronary arteries were normal. We propose that the runner died from myocardial ischaemia, precipitated by marathon running on a background of hypertrophic cardiomyop...

The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in...

The blood glucose response of a male ultramarathon runner was monitored throughout a 1005-km race. Before the race the runner had a fasting blood glucose concentration of 5.1 mM. At no stage during the race were his mean blood glucose levels less than 5.8 mM. This was partially attributed to the eating patterns of the athlete, the times at which blood samples were taken, the glycaemic index of ...

Verticillium wilt, caused by Verticillium dahliae, is widespread in intensive strawberry (Fragaria ananassa) growing areas. It is effectively controlled in site preparation by soil fumigation with methyl bromide but with the ban on ozone-depleting chemicals, which applies to methyl bromide, there has been an international effort to find alternatives, which will protect the crop from planting to...

The etiology of running injuries is multifactorial in nature. These factors can be simplified into those related to structure, mechanics and dosage. In order to fully understand the cause of an injury, one must carefully assess each of these factors. This includes taking a thorough history, as well as an evaluation of runner’s structure and alignment. However, if the injury occurred during the ...

This paper presents an integrated portable measurement system for the study of high speed and high temperature unsteady plasma flows such as those found in the vicinity of high current switching arcs. The system permits direct and non-intrusive measurement of arc light emission images with a capture rate of 1 million images per second (1MHz), and 8 bit intensity resolution. Novel software techn...

One-dimensional stability analysis of a hydraulic system composed of a penstock, a runner, and a draft tube was carried out to determine the cause of the full load draft tube surge. It is assumed that the cavity volume at the runner exit is a function of the pressure at the vortex core evaluated from the instantaneous local pressure at the runner exit and an additional pressure decrease due to ...

In this paper a general approach to gate array routing is presented, based on an abstract routing space model. An efficient k–terminal net maze runner is described. It does not partition nets into 2–terminal net routing problems, but solves the problem by simultaneously growing k search waves. It is shown that the explored routing space diminishes when compared to bi–directional routing schemes...
