Detection of methicillin resistance in Staphylococcus aureus is a challenge, especially low-level resistance, which is often misdiagnosed. The aim of this study was to compare the diagnostic accuracies of the automated Vitek 2 system and disk diffusion tests, using cefoxitin and moxalactam, for the detection of methicillin resistance in S. aureus strains. Four sets of genotypically diverse isol...

Tile problem of planctary system formation and its subsequent character can only be addressed by studying the global evolution of solid material entrained in gaseous protoplanetary disks. We start to investigate this problem by considering the space-time development of aerodynamic forces that cause solid particles to dccouple from the gas. The aim of this work is to demonstrate that only the sm...

Few experiments in the coastal plain region of the southeastern United States have reported the effect of long-term tillage and tillage intensity on chemical soil quality indicators. The purpose of this study was to determine the 17-year influence of four tillage systems on chemical soil quality indicators in a Benndale fine sandy loam (coarse-loamy, siliceous, semiactive, thermic, Typic Paleud...

This paper describes a programming framework for clean construction of disk maintenance applications. They can use it to expose the disk activity to be done, and then process completed requests as they are reported. The system ensures that these applications make steady forward progress without competing for disk access with a system’s primary applications. It opportunistically completes mainte...

Recent studies of photon-generation mechanisms in the color-superconducting Color-Flavor Locked (CFL) phase of dense quark matter have found γ-ray emissivities in excess of ∼ 10 erg cm s for temperatures in the 10-30 MeV range. We suggest that this property can trigger γ-ray bursts (GRBs) and associated fireballs at the surface of hypothetical hot (newly born) quark stars with an energy release...

We discuss constraints on the physics of the inner accretion disk, as well as the properties of the black hole itself, that can be derived by a detailed examination of the relativistically broadened spectral features (especially the fluorescent iron line) in the Seyfert galaxy MCG–6-30-15. To begin with, we show that spectral models which purport to eliminate the broad iron line in MCG–6-30-15 ...

This paper describes a programming model and system support for clean construction of disk maintenance applications. Such applications expose the disk activity to be done, and then process completed requests as they are reported. The system ensures that these applications make steady forward progress without competing for disk access with a system's primary applications. It opportunistically co...

We made multi-band radio observations of NGC 2997, including total power mapping at λ20 with the Very Large Array (VLA), sensitive polarization observations at λ13 cm with the Australia Telescope Compact Array (ATCA) and images at λ6 and λ3 cm with the VLA. The detected regular magnetic field extends from the centre to the outer disk. In the central part (galactic radius R ≤ 0.5′), the dominate...

BACKGROUND Ventilation with low tidal volume is recommended for patients with acute lung injury. Current guidelines suggest limiting plateau pressure (Pplat) to < 30 cm H2O for septic patients needing mechanical ventilation. The aim of this study was to determine whether Pplat within the first 24 h of ICU admission is predictive of outcome and whether Pplat < 30 cm H2O is associated with lower ...

BACKGROUND Few cases of GIST bigger than 15 cm have been reported in medical literature, all primarily in elderly patients. We report an unusual case, in which a giant gastric GIST - in a young patient - presented as spontaneous intratumoral bleeding followed by intraluminal rupture. CASE PRESENTATION A 37-year-old man was admitted with an acute onset of abdominal pain. CT showed a 32 x 25 cm...
