Fisheries-independent surveys provide critical data products used to estimate stock status and inform management decisions. While it can be possible redistribute sampling effort improve survey efficiency address changing monitoring needs in the face of unforeseen challenges, is important assess consequences such changes. Here, we present an approach that relies on existing simulations evaluate ...

OBJECTIVES The aim of the study was to determine the prevalence of snow crab sensitisation and occupational asthma. STUDY DESIGN Prevalence study of symptoms, pulmonary function testing and allergy testing to crab was conducted in four crab plants of different design in Newfoundland and Labrador, Canada. METHODS Plants workers in four crab plants were interviewed and offered skin testing, R...

While many parts of the world face water scarcity, Bangladesh is fortunate to have an abundance resource. The economic health country depends heavily on fishing industry. Both capture fisheries and culture are common types fisheries. Unlike fisheries, which farming aquatic organisms in closed waters under controlled conditions, typically means harvesting fish other from open waters. This articl...

| The Compton Gamma-Ray Observatory has completed 4 years of observations comprising a full-sky survey and several deep pointings. The Crab is one of the strongest permanent sources in the CGRO energy range (20 keV to 10 GeV). Its total (pulsed and unpulsed) emission is often used as a calibration standard. We present the results of an analysis of data from all four CGRO instruments obtained du...

Due to the fundamental nature of exploration in rough-terrain, a rover accomplishing this task is naturally confronted with an unknown environment. It is especially true regarding its interaction with the soil, as the nature of it is uncertain. This work aims at creating a strategy allowing the rover to learn from its interaction with the terrains encountered, with the goal of optimizing its be...

—Spatial heterogeneity is a striking life history feature of the blue crab Callinectes sapidus in the Chesapeake Bay. Spatial patterns of sexand age-specific habitat use have been well documented and affect the fisheries in the bay. However, a quantitative assessment of the spatial distribution of blue crabs during winter, when they are generally buried in the sediments, has been lacking. We ap...

Background: Prostate cancer is the second most common cancer in men worldwide and the third most common cancer in Iranian men. Chemotherapy is used to treat this cancer, but it has toxic effect. Natural compounds found in marine organisms and plants have anticancer considered. The aim of the present study was to investigate the effect of crab shell extract on induction of apoptosis in prostate ...

Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compar...

For many astrophysical sources with jets, there is evidence for the contemporaneous presence of disks. In contrast, pulsars such as the Crab and Vela show jets but have not yet revealed direct evidence for accretion disks. Here we show that for such pulsars, an accretion disk radiating below detectable thresholds may simultaneously account for (1) observed deviations in the braking indices from...
