1. A Meta-analysis to Quantify the Risk of Disseminated Gonococcal Infection With Porin B Serotype.

Author

Subjects
*GONORRHEA, *NEISSERIA gonorrhoeae, *MEMBRANE proteins, *ALLELES
Abstract

The escalating rates of gonorrhea globally are associated with higher numbers of disseminated gonococcal infection (DGI). Expression of the PorB1A allele of the major outer membrane porin protein, PorB, is associated with DGI. This meta-analysis shows that the odds of PorB1A strains to disseminate is 20.53 compared to PorB1B isolates. [ABSTRACT FROM AUTHOR]

4. Bond Strength of Reinforcement Affected by Concrete Sedimentation.

Author

WELCH, GEOFFREY B. and PATTEN, BRUCE J. F.

Abstract

Experimental investigations to examine the effect of concrete sedimentation characteristics on pull-out bond strengths are reported. Concretes of the same compressive strength but varying settlement and bleeding were used with plain round, square, twisted, and deformed bars. The general trend of the results indicated that increased concrete settlement in all cases led to reduced bond of rigidly positioned, horizontal bars, even with small depths of plastic concrete beneath the bars.
