A complete set of closed analytical expressions is presented in a unified manner for the internal displacements and strains due to shear and tensile faults in a half-space for both point and finite rectangular sources. These expressions are particularly compact and systematically composed of terms

and the effects of the stresses and strains of life-which alter the metabolic activity. The universality of this phenomenon sug-gests that the reactions which cause it are basic-ally the same in all living things. Viewing this process in the light of present day free radical and radiation chemistry

The genome sequences of two virulent strains of Mycobacterium tuberculosis (H37Rv and CDC 1551) are now available. CDC 1551 is a recent clinical isolate and H37Rv is a commonly used lab strain which has been subject to in vitro passage. The two strains have been shown to display differing

-RFLP) for 1,002 eubacterial sequences showed that with proper selection of PCR primers and restriction enzymes, 686 sequences could be PCR amplified and classified into 233 unique terminal restriction fragment lengths or "ribotypes." Using T-RFLP, we were able to distinguish all bacterial strains

strains, and daily hassles. Life events are acute changes which require major behavioral readjustments within a relatively short period of time (e.g., birth of first child, divorce). Chronic strains are persistent or recurrent demands which require readjustments over prolonged periods of time (e

strategy to simultaneously determine relative protein levels in three yeast strains and provide a demonstration of the ability to measure the absolute quantity of specific target proteins From ‡Applied Biosystems, Framingham, MA 01701; §Cancer Research UK,

outweighs the contribution of horizontal gene transfer in the expansion of protein families. We analyzed closely related prokaryote strains or species with small genomes (Helicobacter, Neisseria, Streptococcus, Sulfolobus), average-sized genomes (Bacillus, Enterobacteriaceae), and large genomes (Pseudomonas

The mechanism of initiation of translation differs between prokaryotes and eukaryotes, and the strategies used for regulation differ accordingly. Translation in prokaryotes is usually regulated by blocking access to the initiation site. This is accomplished via base-paired structures (within the m

ABSTRACT We describe a suffix-tree algorithm that can align the entire genome sequences of eukaryotic and prokaryotic organisms with minimal use of computer time and memory. The new system, MUMmer 2, runs three times faster while using one-third as much memory as the original MUMmer system. It has
