Swelling of gun barrels is an occurrence which is usually explained by the presence of dirt. This work demonstrates that it results from the intersection of the barrel and bullet hardness curves which activates the failure mechanism suggested by the two-temperature-gradients model. The presence of dirt can be a favourable but not a necessary condition for Nike Air Max 2010 Canada
this type of failure to occur.

wood to endure impact loading have arisen in the immediate past from naval requirements and these are briefly discussed.A short summary of the nature of wood is provided and then some contemporary sources of information about its impact behaviour are given. A commonly used sectionalpressure approach for approximately determining the depth of penetration into wood by a projectile is advocated.
The concepts of aF(C, D)-pseudomonotone mapping and of a (C, D)-pseudomonotone pair of mappings are introduced. By employing Fan's lemma, we establish several existence results for generalized vector equilibrium problems. The new results extend and modify various existence theorems for similar problems.
The14C activities of North Atlantic water at Geosecs stations 5, 27, and 29 are reported. The influence of the correction for isotope fractionation on the14C results is discussed, and experimental procedures are given.
