Evaluation of batch test for measurement of active biomass in activated sludge mixed liquor
No full textIncludes bibliographical references.Over the past two decades significant advances have been made in the areas of engineering (design) and technology (implementation and operation) of the single sludge activated sludge system. Activated sludge systems have been successfully designed and implemented at full-scale for the biological removal of carbon (C), nitrogen (N) and phosphorus (P). This implementation has been aided by the development of a suite of steady state design models (e.g. WRC, 1984; Wentzel et aI., 1990; Maurer and Gujer, 1994) and kinetic simulation models (e.g. Dold et al., 1980, 1991; Van Haandel et aI., 1981; Henze et al. , 1987; Wentzel et aI., 1992; Henze et al., 1995)

Analyzing reversible changes in hygroscopicity of thermally modified eucalypt wood from open and closed reactor systems
No full textInfrastructure and service delivery - lessons from SA and China
No full textThe HSRC conducted a collaborative study with the Chinese Academy of Social Science (CASS) to explore aspects of best practice in service delivery in terms of water, sanitation and electricity. The study found that important obstacles to service delivery fall within the governance, policies, programmes and stakeholder relationships of local government practices, i.e the intangible aspects of service delivery. Elmé Vivier and Marie Wentzel report.

Intimin-mediated export of passenger proteins requires maintenance of a translocation-competent conformation
No full textIntimins from pathogenic bacteria promote intimate bacterial adhesion to epithelial cells. Several structurally similar domains form on the bacterial cell surface an extended rigid rod that exposes the carboxy-terminal domain, which interacts with the translocated intimin receptor. We constructed a series of intimin-derived fusion proteins consisting of carboxy-terminally truncated intimin and the immunoglobulin light-chain variable domain REIv, ubiquitin, calmodulin, beta-lactamase inhibitor protein, or betan-lactamase. By systematically investigating the intimin-mediated cell surface exposure of these passenger domains in the presence or absence of compounds that interfere with outer membrane stability or passenger domain folding, we acquired experimental evidence that intimin-mediated protein export across the outer membrane requires, prior to export, the maintenance of a translocation-competent conformation that may be distinct from the final protein structure. We propose that, during export, competition exists between productive translocation and folding of the passenger domain in the periplasm into a stable conformation that is not compatible with translocation through the bacterial outer membrane. These results may expand understanding of the mechanism by which intimins are inserted into the outer membrane and expose extracellular domains on the cell surface
