Classifying proteins into families and identifying important domains and sites is invaluable for helping biologists to identify distantly related proteins and to predict their functions. A daunting array of resources, each with different strengths and weaknesses, is now available for searching genomes and proteomes with ‘protein signatures’ – diagnostic entities that are used to recognise a par...

The adhesion of Streptococcus mitis to solid substrata from phosphate suspensions with various ionic strengths was studied and compared with the adhesion of polystyrene particles. At all ionic strengths, the interfacial free energy of adhesion governed the relative number of bacteria or polystyrene particles adhering at equilibrium, except that in a low-ionic-strength buffer, adhesion occurred ...

We investigate known security flaws in the context of security ceremonies to gain an understanding of the ceremony analysis process. The term security ceremonies is used to describe a system of protocols and humans which interact for a specific purpose. Security ceremonies and ceremony analysis is an area of research in its infancy, and we explore the basic principles involved to better underst...

per cent., using standard Kahn antigen. An immediate reading is made after shaking and the addition of the appropriate strengths of saline, followed by further readings after 4 and 24 hours' incubation at 4 to 6° C. The method thus combines features of the differential temperature and triple quantitative techniques previously described (Kahn, 1940, 1942), and includes a standard Kahn test. Varying

We present extensive and accurate calculations for the excited-state spectrum of spin-polarized neutral helium in a range of magnetic field strengths up to 10 G. Of considerable interest to models of magnetic white dwarf stellar atmospheres, we also present results for the dipole strengths of the low-lying transitions among these states. Our methods rely on a systematically saturated basis set ...

Inadequate access to preventive oral health services contributes to oral health disparities and is a major public health concern in the United States. Federally Qualified Health Centers play a critical role in improving access to care for populations affected by oral health disparities but face a number of administrative challenges associated with implementation of oral health integration model...

SUMMARY. Chinese family and marriage strengths and challenges are delineated in this article, including equity in marriage, affection, the ability to adapt to changes, mutual trust, compatibility, harmony, and family support. Despite the fact that Chinese households are getting smaller as a result of governmental policy and the broadening of housing markets, families remain crucial support netw...
