A Three-Component Regulatory System Regulates Biofilm Maturation And Type Iii Secretion In Pseudomonas Aeruginosa, Sherry L. Kuchma, John P. Connolly, George A. O'Toole
Dartmouth Scholarship
Biofilms are structured communities found associated with a wide range of surfaces. Here we report the identification of a three-component regulatory system required for biofilm maturation by Pseudomonas aeruginosa strain PA14. A transposon mutation that altered biofilm formation in a 96-well dish assay originally defined this locus, which is comprised of genes for a putative sensor histidine kinase and two response regulators and has been designated sadARS. Nonpolar mutations in any of the sadARS genes result in biofilms with an altered mature structure but do not confer defects in growth or early biofilm formation, swimming, or twitching motility. After …

We present an analysis of the Hipparcos photometry of the contact binary systems UX Ret and CN Hyi. The Wilson-Devinney code is employed to model the V band light curve for several fixed values of the mass ratio. From the quality-of-fit of the different solutions a final solution is derived for each system. Absolute values of the system are derived using the parallax data from the Hipparcos catalog. Analysis of the V band photometry of two stars (EL Aqr and FN Cam) with spectroscopically known mass ratios is also provided as a validation for the methods adopted for this study.

Formal Concept Analysis can be used to obtain both a natural clustering of documents along with a partial ordering over those clusters. The application of Formal Concept Analysis requires input to be in the form of a binary relation between two sets. This paper investigates how a semantic filesystem can be used to generate such binary relations. The manner in which the binary relation is generated impacts how useful the result of Formal Concept Analysis will be for navigating one’s filesystem.

This study presents the results of the analyses of the coprolite material found among the skeletal remains in M6, a burial chamber discovered in the necropolis of the Van-Yoncatepe Castle, which dates back to the beginning of the 1^{st} millennium BC (Early Iron Age). For this purpose, microbiological and parasitological examinations, as well as biochemical analyses have been carried out. Because the crystallisation values were so high, the parasite evidences could not been revealed. As a result of the microbiological examination, no micro-organisms were isolated. As for the biochemical analyses performed, the material was tested for glucose, uric acid, cholesterol, …
