Prawn, shrimp and crabs sold in Japan are mostly imported from overseas. Detection of irradiated crustaceans is very important for quality assurance. In this study, we used ESR to detect radiation-induced radicals after irradiation of prawn, shrimp and crabs of major species. No radiation-induced radicals were detected in prawn (black tiger prawn) or shrimp (white leg shrimp). Radiation-induced...

A model of an accelerated expansion of the Crab Nebula powered by the spinning-down Crab pulsar is proposed, in which time dependence of the acceleration is connected with evolution of pulsar luminosity. Using recent observational data, we derive estimates of the Crab neutron-star moment of inertia. Correlations between the neutron star moment of inertia and its mass and radius allow for rough ...

The Corps of Engineers Integrated Compartment Water Quality Model (CE-QUAL-ICM or simply ICM) was designed to be a flexible, widely applicable eutrophication model. Ecopath with Ecosim (EWE) is a freely distributed network model supported by the Fisheries Centre, University of British Columbia. This study aimed to develop a coupling between the two models so that they could be used, in combinat...

typing analysis, which would contribute to the knowledge of the molecular epidemiology of CRAB isolates. Although many distinct sequence types of CRAB, including some international clones, have been identified in Brazil, there still are no data from this Brazilian region. In summary, we demonstrated the persistence of a few clones responsible for endemic levels of CRAB isolates in hospitals in ...

The possible involvement of opioid system in the regulation of hemolymph glucose level in the fresh water crab Oziotelphusa senex senex Fabricius, was investigated. Opioid agonist and antagonist was also used in addition to methionine-enkephalin itself. Injection of the opioid, methionine-enkephalin and FK 33-824 significantly elevated hemolymph glucose level. In contrast, injection of naloxone...

Many exploration rovers have been proposed in the past, but none was compared to other systems. Therefore, this paper not only introduces the locomotion concept CRAB, but also compares it to other rovers regarding obstacle negotiation capabilities. Instead of relying only on simulation, a comparison was also performed with real breadboards. In reality the CRAB is compared to RCL-E (Concept E by...

The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision. The crab cavity is chosen to have the same frequency as the main linac (11.9942 GHz) as a compromise between size, phase stability requirements and beam loadin...

An investigation was conducted to estimate approximate production and assess the marketing of mud crab in the south-western region of Bangladesh. Crab culture was done by hardening and fattening collected from the natural source. Most of the fattening farms were 0.2 to 2 acres. Fattening and hardening period varied from 10 to 30 days. The Sundarban mangrove, tidal rivers, estuaries, canals, shr...

Carcinus maenas (Green Crab) is an invasive crab species on the east and west coasts of the United States dating back to 1817. The introduction of another invasive species in 1988, Hemigrapsus sanguineus (Asian Shore Crab), has created competitive interactions between the crabs. A demographic study was conducted to compare crab populations. A total of 155 crabs were collected, 25 of which were ...

Problem from eating poisonous seafood can be seen in marine medicine[1-3]. Several marine animals can be toxic. The good examples are fishes[4], mussels[5] and shellfishes[6,7]. Horseshoe crab (Carcinoscorpius rotundicauda) can be poisonous and intoxication due to intake is possible[8]. Horseshoe crab poisoning can be seen in many countries with seacoasts including China and Thailand. In animal...
