Theory and simulation results have demonstrated that four, variable speed flywheels could potentially provide the energy storage and attitude control functions of existing batteries and control moment gyros on a satellite. Past modeling and control algorithms were based on the assumption of rigidity in the flywheel’s bearings and the satellite structure. This paper provides simulation results a...

Tn5-tagged invasion plasmid DNA (pWR110) from Shigella flexneri serotype 5 (strain M90T) was cloned into the expression vector lambda gt11. Recombinant phage (lambda gt11Sfl) expressing pWR110-encoded polypeptide antigens were identified by using rabbit antisera directed against S. flexneri M90T invasion plasmid antigens. Antigens encoded by lambda gt11Sfl recombinant phage were characterized b...

Abstract Cellulose mixed esters (CMEs) substituted with two different types of acyl groups are promising polymeric materials various tunable properties but arduous to produce. This is because the insolubility cellulose in common solvents, and thus, industrial production CMEs desired degrees substitution (DSs) requires a costly multistep process. To accomplish their facile production, homogeneou...

Background/Aim: The classification of periampullary adenocarcinomas into pancreatobiliary-type adenocarcinoma and intestinal-type (PPAC IPAC, respectively) has gained significant acceptance in the medical community. A patient's prognosis is determined by degree differentiation these tumor types. objective present investigation was to assess efficacy volumetric apparent diffusion coefficient (AD...

Recent studies have found the earth's peculiar velocity to be significant in microwave background based tests for compact cosmic topology, and modifications to these tests have been proposed. Tests of non-gaussianity, weak lensing analysis and new tests using improved CMB data will also be sensitive to peculiar velocity. We propose here to simplify matters by showing how to construct a deaberra...

Recent studies have found the earth’s peculiar velocity to be significant in microwave-background–based tests for compact cosmic topology, and modifications to these tests have been proposed. Tests of non-Gaussianity, weaklensing analysis, and new tests using improved cosmic microwave background (CMB) data will also be sensitive to peculiar velocity. We propose here to simplify matters by showi...

A 31-kb fragment of the large virulence plasmid of Shigella flexneri is necessary for bacterial entry into epithelial cells in vitro. One locus of this fragment encodes the IpaA, -B, -C, and -D proteins, which are the dominant antigens of the humoral immune response during shigellosis. To address the role of the ipa genes, which are clustered in an operon, we constructed a selectable cassette t...

The antigen preparation most often used for determining the levels of antibodies to virulence-associated proteins of Shigella spp. consists of a mixture of proteins (including IpaB, IpaC, IpaD, and VirG*) extracted from virulent shigellae with water (water extract). To overcome the lack of specificity for individual antigens in the water-extract enzyme-linked immunosorbent assay (ELISA), the ip...
