In the Atlantic and Gulf states, the crab pot fishery overlaps with much of the habitat of the diamondback terrapin, Malaclemys terrapin. The exclusively estuarine terrapin can be found throughout the coastal bays and creeks of the eastern and Gulf coasts of the United States. Terrapin populations can incur considerable mortality of males and juveniles when crab pots are fished in terrapin habi...

Content of mercury in hepatopancreas, muscle and exoskeleton of blue crab T. prymna from Musa estuary and their relationship with size of the organism and season were determined. Mean concentration of mercury in hepatopancreas, muscle and exoskeleton were 1.23, 0.61 and 0.41 µg/g dw, respectively. There was significant difference (p<0.05) in mercury levels depending on the sex with greater ...

Carbapenem-resistant Acinetobacter baumannii (CRAB) infections are increasing, and they are associated with an increased risk of mortality in hospitalized patients. Linear regression is commonly used to identify concurrent trends, but it cannot quantify the relationship between risk factors and resistance. We developed a model to quantify the impact of antibiotic consumption on the prevalence o...

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...
