Sequence analysis of environmental DNA promises to provide new insights into the ecology and biogeochemistry of uncultured marine microbes. In this study we used the Sargasso Sea Whole Genome Sequence (WGS) data set to search for hydrolases used by Cytophaga-like bacteria to degrade biopolymers such as polysaccharides and proteins. Analysis of the Sargasso WGS data for contigs bearing both the ...

This study investigates the influence of substrate (AISI M42 tool steel) bias voltage (from −30 to −80 V), on mechanical properties magnetron sputtered TiSiN coating derived from Ti and Si targets. Thermal stability, microstructure (crystallite size, microstrain, lattice constant), morphology (hardness, Young's modulus, residual stresses) properties, deposited coatings, were investigated with s...

Bacterial aminopeptidases play important roles in pathogenesis by providing a source of amino acids from exogenous proteins, destroying host immunological effector peptides and executing posttranslational modification of bacterial and host proteins. We show that MHJ_0125 from the swine respiratory pathogen Mycoplasma hyopneumoniae represents a new member of the M42 class of bacterial aminopepti...

Strategic models of auditor-inspectee interaction have neglected implementation details in multiple-inspectee settings. With multiple inspectees, the target audit probability derived from the standard analysis can be implemented with sampling plans differing in the budgets committed to support them. Overly-committed audit budgets tie up unneeded resources that could have been allocated for bett...

BACKGROUND/AIM Periodontal disease affects gingival tissue and supporting apparatus of the teeth leading to its decay. The aim of this study was to highlight and precisely determine his- tological changes in the gum tissue. METHODS Gingival biopsy samples from 53 healthy and parodontopathy-affected patients were used. Clinical staging of the disease was performed. Tissue specimens were fixed ...

The emission-line regions of starburst galaxies and active nuclei reveal a wealth of spectroscopic information. A unified picture of the relationship among ionized, atomic, and molecular gas makes it possible to better understand these observations. We performed a series of calculations designed to determine the equation of state—the relationship among density, temperature, and pressure—through...

This paper presents an analysis of [Fe IV] emission based on new identifications and previous measurements of [Fe IV] lines in 30 Doradus, IC 4846, M42, SMC N88A, and SBS 0335−052. The Fe abundances obtained by adding the abundances of the relevant Fe ions (mainly Fe ++ and Fe 3+) are found to be lower, by factors in the range 2.6–5.9, than the Fe abundances implied by [Fe III] emission and an ...

A detailed study of the Hourglass Nebula in the M8 star forming region is presented. The study is mainly based on recent subarcsec-resolution JHKs images taken at Las Campanas Observatory and complemented with archival HST images and longslit spectroscopy retrieved from the ESO Archive Facility. Using the new numerical code CHORIZOS, we estimate the distance to the earliest stars in the region ...
