Acute aortic dissection - forensic medicine aspects

Wem investigated some forensic-edical aspects and medico-biological aspects of aortic aneurisms. We examined 2574 forensic autopsies from 1998 to 2004 years. There were studied the following data - sex, age, reasons for the development of the aneurysms, the localization of the intimal lesions, complications and chronobiological pecularities. The level of alcohol were established by Widmark method. We found 20 cases with acute aortic dissection aneurysms (0,78%). The most often place of death is home (45%) and work (20%). The men were more than twice (70% men and 30% women). The average age of the men (55,71) was considerably lower than women's (68,67). The most affected age group (50-79) occupied 75% from all cases. The main etiologic factor was hypertonia and atherosclerosis (70%), in 20% - only hypertonia. We observed intimal lesions 1 sm and 2 sm above aortic valve. The wall of the left ventricle with hypertonia and atherosclerosis showed 21,86 mm. In 85% of the cases we found cardiac tamponada. There were chronobiological peculiarities in sudden death from aortic aneurysms

Weakly Symmetric Graphs, Elementary Landscapes, and the TSP

AbstractWeakly symmetric graphs are defined and their construction from symmetric graphs is explained. It is shown that the TSP on a weakly symmetric graph joined with each of a number of well-known local search neighbourhoods yields elementary landscapes (in which local minima are better than the average). In conclusion, an O(n2) algorithm for identifying weakly symmetric graphs is described
