We report the draft genomes of twoSphingopyxissp. strains isolated from a chloraminated drinking water distribution system simulator. Both strains are ubiquitous residents and early colonizers of water distribution systems. Genomic annotation identified a class 1 integron (intI1) gene associated with sulfonamide (sul1) and puromycin (pac) antibiotic resistance genes.

BACKGROUND Fumonisin B(1) is a cancerogenic mycotoxin produced by Fusarium verticillioides and other fungi. Sphingopyxis sp. MTA144 can degrade fumonisin B(1), and a key enzyme in the catabolic pathway is an aminotransferase which removes the C2-amino group from hydrolyzed fumonisin B(1). In order to study this aminotransferase with respect to a possible future application in enzymatic fumonisi...

Title of Document: LEGISLATING HEALTHCARE QUALITY. Beomsoo Kim, Doctor of Philosophy, 2006 Directed By: Professor, William N. Evans, Department of Economics Health care market has often been regulated by government legislation. A California law passed in 1999 regulating minimum nurse to patient ratios in hospital units is one of them. This legislation was prompted by results from previous resea...

In this paper, we present a genetic algorithm with a very small population and a reinitialization process (a micro genetic algorithm) for solving multiobjective optimization problems. Our approach uses three forms of elitism, including an external memory (or secondary population) to keep the nondominated solutions found along the evolutionary process. We validate our proposal using several engi...

This paper formulates a stochastic optimal stopping model for the replacement of mainframe computer systems in the telecommunications industry. It describes the replacement behavior by focusing on unique features of computer systems, which are associated with technological development. The optimal stopping rule is the solution of a stochastic dynamic programming model that specifies the system ...

To the Editor: The genus Sphingomonas was proposed by Yabuuchi et al. in 1990 (1) and amended by Takeuchi et al. in 1993 (2). It now has been subdivided into 4 separate genera: Sphingomonas sensu stricto, Sphingobium, Novosphingobium, and Sphingopyxis. The bacteria of the genus Sphingomonas are yellow-pigmented, nonfermenting, gramnegative bacilli with a single polar fl agellum; they are widely...

Our focus has been on the design and analysis of metamaterials that will lead to the realization of new classes of devices. In large part, the materials are not defined by lithography, and hence are amenable to inexpensive large-scale manufacture. Nonlinear optimization methods have been used to design structures that are based on anisotropic metamaterials and operate as efficient energy collec...

Rat liver gap junctions were isolated in Ca2+-free media and analyzed in controlled environments by x-ray diffraction of partially oriented pellets. Different treatments of the same preparations were compared. The ordered hexagonal lattices gave rise to detail that was sensitive to low Ca 2+ concentrations (0.05 mM), but not to Mg 2+ (up to 0.16 mM) or pH (between 6.0 and 8.0). The major Ca2+-m...

This study addresses the call for increased research on common public school practices and progress monitoring by public school teachers. An alternating treatment design was implemented by a preschool teacher to evaluate the effect of sensory-integration based activities compared with an attention control on the on task behavior of three participants with disabilities. The preschool participant...
