A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...

Transducing bacteriophages CP-51 and CP-53 were compared. Unlike CP-51, CP-53 appeared to be a lysogenizing phage. CP-51 gave greater frequencies of co-transduction for linked markers than did CP-53. CP-51 was found to be a larger phage which carried more deoxyribonucleic acid (DNA) than CP-53. CP-51 DNA contained about 43% guanine plus cytosine and in addition contained 5-hydroxymethyluracil i...

Four patterns intended to support the development of embedded systems are presented in this paper. These patterns are written for developers of software, and some associated hardware, for the ubiquitous 8051 family of microcontrollers. There are primarily intended to assist software developers who have experience in ‘desktop’ software development (in C or a related language) in the process of a...

The relative rate at which ribosomal protein 51 (rp51) mRNA is synthesized was measured by pulse-labeling cells in vivo with [3H]adenine. Two strains of Saccharomyces cerevisiae were compared: A364A (wild type) and ts368 (rna2), a temperature-sensitive strain in which the level of rp51 mRNA decreases and an intron-containing rp51 precursor RNA increases. When cells were shifted up to the nonper...

THE PRIVATE HEALTH insurance industry in the United States is made up of three broad categories: Blue Cross and Blue Shield associations, commercial insurance companies, and independent plans. In 1970 these private health insurance organizations provided some protection to approximately four-fifths of the civilian population-against the costs of hospital care and surgical care. For 72 percent o...

A woman's life expectancy has increased from 48.3 years in 1900 to 79.4 years in 1997 . Today, our challenge is to make those extra years of life healthy and productive . Women represent 51 percent of the total U.S . population ; 59 percent of the over-65 population ; and 71 percent of Americans older than age 85, the fastest growing segment of the population . Women also constitute 46 percent ...

BACKGROUND Type 2 diabetes affects approximately 8 percent of adults in the United States. Some risk factors--elevated plasma glucose concentrations in the fasting state and after an oral glucose load, overweight, and a sedentary lifestyle--are potentially reversible. We hypothesized that modifying these factors with a lifestyle-intervention program or the administration of metformin would prev...

This chapter highlights the persistence of ethnicity in Bolivian politics and society when viewed over the long term, intertwined with such other key factors as the development of a national state and class conflict. The 2001 census provides the most recent data on how Bolivians classify themselves ethnically. This census asked people over the age of fifteen to state which ethnic group they tho...
