The comparison of nucleotide or protein sequences from the same or different organisms is a very powerful tool in molecular biology. By finding similarities between sequences, scientists can infer the function of newly sequenced genes, predict new members of gene families, and explore evolutionary relationships. Now that whole genomes are being sequenced, sequence similarity searching can be us...

The paper defines and describes blast waves, their interaction with a structure and its subsequent response. Explosions generate blast waves, which need not be due to explosives. A blast wave consists of two parts: a shock wave and a blast wind. The paper explains how shock waves are formed and their basic properties.The physics of blast waves is non-linear and therefore non-intuitive. To under...

purpose: in recent years high explosive bomb attacks have been increasingly directed against   civil structures by various terrorist organizations. this paper describes a numerical method for   assessing the interaction of high explosive air blast within the complex geometrical type of a   congested urban environment.   materials and methods: the first step in predicting blast effects on a targ...
