The inelasticity in nucleus-nucleus collisions at high energies is calculated in the framework of geometrical multichain model. The very fast increase of the inelasticity is found as a result of a second-stage cascading process. The same behaviour is expected for all the models using the wounded nucleon idea. The simple formula for the number of wounded nucleons inside colliding nuclei does not...

Between the initial excitation of nucleons by the passing throughout each other and the final cascading of newly created hadrons there should be considered one more step. We call it the second step cascading process. It acts as an interaction of wounded nucleon from one nucleus with another nucleon from the same nucleus. This mechanism leads to the significant increase on the inelasticity for n...

Each Tuesday, the U.S. Department of Defense provides an online update of American military casualties (the number of wounded or dead) from Operation Iraqi Freedom and Operation Enduring Freedom.1 According to this update, as of November 16, 2004, a total of 10,726 service members had suffered war injuries. Of these, 1361 died, 1004 of them killed in action; 5174 were wounded in action and coul...

In the first 6.5 years of Operation Iraqi Freedom (OIF), U.S. military casualties exceeded 3,400 hostile deaths, 800 nonhostile deaths (due to disease, nonbattle injury, and other causes), and over 31,000 troops wounded in action. Casualty rates in Iraq have been considerably lower that during the Vietnam conflict, and a greater proportion of troops wounded in Iraq survive their wounds. Before ...

Proteinase inhibitors were extracted from the upper leaves of tomato plants, Lycopersicon esculentum Mill., 48 hours after wounding single lower leaves. Inhibitors were partially purified by affinity chromatography and isoelectric focusing. Significantly higher levels of trypsin and chymotrypsin inhibitory activity were recovered from wounded plants than from unwounded controls. Several inhibit...

Polymorphonuclear invasion of the wounded rat cornea is quantitatively described. The inflammatory cells enter the wounded tissue during the 5th postoperative hour. They steadily increase in number until they reach a maximum between 24 and 36 hours and return to normal by about the 6th day. Six hour wounds are used to evaluate the influence of topically applied drugs on the polymorphonuclear in...
