BACKGROUND It is unknown whether there are differences between bacteremia caused by carbapenem resistant Acinetobacter baumannii (CRAB) and carbapenem resistant Acinetobacter nosocomialis (CRAN). This study aims to investigate the differences, especially in clinical outcomes, between patients with bacteremia caused by CRAB or CRAN. METHODS This is a 9-year retrospective study comparing the cl...

We present near-infrared observations obtained with ISAAC on the VLT of the Crab pulsar and its environment. Photometry of the pulsar in Js, H and Ks shows the pulsar spectrum to extend fairly smoothly from the UV/optical regime. PSF subtraction of the pulsar allows us to study its immediate neighborhood in some detail. In particular, the knot positioned just 0. ′′6 from the pulsar has been rev...

The size composition, growth pattern, sex ratio and feeding habits of the blue swimming crab, Portunus segnis from Persian Gulf in south of Iran, was studied. Sampling was performed by trawl net during a one- year period (July 2011 to May 2012) as processed 864 crabs was collection. The crabs carapace width ranged were from 7.5-17.5 cm for males and 7.0-16.5 cm for females. The crab ca...

  Baseline ecological studies of Pondicherry mangroves are important for monitoring, management and conservation of mangrove ecosystems. A brachyuran crab faunal assemblage at four stations of Pondicherry mangroves is described and monthly samplings were made during September 2008 – August 2009. Totally 22 species of brachyuran crabs belonging to 12 genera and 5 families were recorded crabs bel...

The H I environment of the Crab Nebula is investigated using 2.75 ′ and 9 ′ resolution data from (respectively) the DRAO Synthesis, and Effelsberg 100 m, radio telescopes. No clear evidence for an interaction between the Crab and the surrounding H I is found; the Crab probably lies within the boundaries of a large scale, low-density void in the H I distribution. The presence of a wind-blown H I...

The mussel aquaculture industry has raised concerns following the discovery of green crab Carcinus maenas in Placentia Bay Newfoundland in August 2007. Post-larval green crabs have been found in feral mussel beds in high densities in Europe. If this is true for other green crab populations, mussel seed transfers from Placentia Bay could provide a vector for post-larval juvenile crab transfer to...

l. The mechanical behaviour of crab shell is similar to that of prawn solid cuticle, especially in the occurrence of a low strain discontinuity in their bulk tensile stress-strain curves. 2. Although isolated crab chitin breaks in tension by the progressive failure of individual lamellae and exhibits post-fracture delamination, whole crab cuticle fails in an entirely brittle manner. 3. The mech...

The role of predation in structuring soft-sediment communities varies as a function of the number and composition of predators that co-occur in a given habitat. In Bonne Bay, Newfoundland, contrasting abundances or predators in different areas of the bay may contribute to different regulatory roles of predators on infauna. To test this hypothesis, results from a field exclusion experiment were ...

The HL-LHC upgrade will use deflecting (or crab) cavities to compensate for geometric luminosity loss at low *  and non-zero crossing angle. A local scheme with crab cavity pairs across the IPs is used employing compact crab cavities at 400 MHz. Design of the cavities, the cryomodules and the RF system is well advanced. The LHC crab cavities will be validated initially with proton beam in the ...

objective: prostate cancer is the second most common cancer worldwide. chemotherapeutic agents have been shown to have adverse side-effects, and natural compounds have been recommended for cancer treatment, nowadays. crab shell has been shown to have cancer preventative and suppressive effects in vivo and in vitro. the aim of present study was to investigate the effect of crab shell extract on ...
