Complete Genome Sequence of the Agarase-Producing Marine Bacterium Strain S89, Representing a Novel Species of the Genus Alteromonas

We report here the annotated genome sequence of the marine bacterium Alteromonas sp. S89 and the identification of six genes coding for agar-degrading enzymes. The sequenced Alteromonas sp. S89 genome is composed of a 3,864,871-bp circular chromosome that includes 3,236 complete open reading frames.

Draft Genome Sequence of Marinobacterium stanieri S30, a Strain Isolated from a Coastal Lagoon in Chuuk State in Micronesia

In this study, we isolated xylan-degrading bacteria from a coastal lagoon of Micronesia and identified the bacteria as Marinobacterium stanieri S30. GSFLX 454 pyrosequencing and sequence analysis of the M. stanieri S30 genome generated 4,007 predicted open reading frames (ORFs) that could be candidate genes for producing enzymes with different catalytic functions.

Complete Genome Sequence of Strain S85, a Novel Member of the Family Flavobacteriaceae

An agar-degrading marine bacterium identified as a novel member of the family Flavobacteriaceae (strain S85) was isolated from seawater in Micronesia. The sequenced strain S85 genome is composed of 3,384,629 bp in a circular chromosome, which includes 2,883 complete open reading frames.

Draft Genome Sequence of the Xylan-Degrading Marine Bacterium Strain S124, Representing a Novel Species of the Genus Oceanicola

We isolated a xylan-degrading bacterium from seawater of Micronesia and identified it as Oceanicola sp. strain S124. We sequenced the Oceanicola sp. S124 genome using GSFLX 454 pyrosequencing and predicted 4,433 open reading frames (ORFs) including putative saccharification and phage-related genes.

Impact Analysis of a Full Model Doublet-Type Spacer Grid in the Fuel Assembly of a PWR

A spacer grid is one of the main structural components in the fuel assembly of a Pressurized Light Water Reactor (PWR). It supports fuel rods and maintains geometry from external impact loads. In ICONE10, a paper was published for impact analysis of a partial model spacer grid. A five by five grid model was established and the analysis results were discussed. At this moment, a full model with a sixteen by sixteen grid is analyzed for impact analysis. This grid has a new doublet-type shape. The finite element model with 16×16 grid cells is established for nonlinear analysis. It is composed of inner straps, outer straps, guide thimbles, etc. The model is considered the aspects of welding and the contacts between the components. The critical impact load that leads to plastic deformation is identified. Nonlinear finite element analysis is carried out by a software system called ABAQUS/EXPLICIT. The results are discussed in the context of the previous results from the partial model and incorporation of the analysis results into the design change is discussed.Copyright
