17. A novel method for measuring health care system performance: experience from QIDS in the Philippines
Objectives Measuring and monitoring health system performance is important albeit controversial. Technical, logistic and financial challenges are formidable. We introduced a system of measurement, which we call Q*, to measure the quality of hospital clinical performance across a range of facilities. This paper describes how Q* was developed, implemented in h

18. Radiation Resistance of Soil Azotobacter
Vela, Gerard R. (School of Aerospace Medicine, Brooks Air Force Base, Tex.), and Orville Wyss. Radiation resistance of soil Azotobacter. J. Bacteriol. 89:1280–1285. 1965.—Quantitative recovery of Azotobacter from soils subjected to γ-radiation from a cobalt-60 source showed the soil populations to be much more highly resistant than isolates from such cu

19. ENZYME ASSOCIATED WITH BACTERIOPHAGE INFECTION
Eklund, Curtis (The University of Texas, Austin) and Orville Wyss. Enzyme associated with bacteriophage infection. J. Bacteriol. 84:1209–1215. 1962.—A capsule-digesting enzyme was formed when azotobacter cells were infected with bacteriophage. The enzyme appeared in the medium when the phages lysed the cells. By disrupting phage-infected cells prematurel

20. Chelation Effects on Azotobacter Cells and Cysts
Goldschmidt, Millicent C. (University of Texas, Austin), and Orville Wyss. Chelation effects on Azotobacter cells and cysts. J. Bacteriol. 91:120–124. 1966.—Ethylenediaminetetraacetate (EDTA) is very toxic to Azotobacter in the presence of nitrogen compounds that form complexes with it. This appears to be due to stronger chelation of certain metal ions b

21. Characterization of Conjugation Factors in Escherichia coli Cell Walls I. Inhibition of Recombination by Cell Walls and Cell Extracts
Lancaster, John H. (University of Texas, Austin), E. P. Goldschmidt, and Orville Wyss. Characterization of conjugation factors in Escherichia coli cell walls. I. Inhibition of recombination by cell walls and cell extracts. J. Bacteriol. 89:1478–1481. 1965.—An assay procedure was devised to determine quantitatively the interference with conjugation of cel

22. Endogenous Encystment of Azotobacter vinelandii
When young cells of Azotobacter vinelandii are impinged on membrane filters, washed free of carbon substrate, and placed on a mineral salts basal medium, the culture will proceed to encyst although at a slower rate than if n-butanol were supplied as a substrate. The endogenous cysts are depleted in polyβ-hydroxybutyrate and have a narrower intine but show a

23. Preparation of Noninfectious Arbovirus Antigens
Noninfectious arbovirus antigens were prepared from borate-saline suspensions of infected suckling mouse brain buffered with tris(hydroxmethyl)aminomethane and treated with β-propiolactone (BPL). The activity and stability of these antigens were enhanced by altering the buffering system, by passing the virus seed through a series of four or more continuous

24. RESISTANCE OF THE AZOTOBACTER CYST
Socolofsky, M. D. (University of Texas, Austin) and Orville Wyss. Resistance of the Azotobacter cyst. J. Bacteriol. 84:119–124. 1962—The Azotobacter cysts were found to be more resistant than the vegetative cells to various harmful agents. Studies involving ultraviolet irradiation indicated that cysts required twice as great a dosage, as correspondingly
