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 ...

In recent years~ severaL species of crab have come under increasing study by scientists. Fluctuations in populations of important commercial species (the blue crab) and the commercial potential of others (the rock crab and deep sea red crab) have led t o this increased attention. But in lab situations, researchers have had problems keeping their specimens alive and healthy for long periods. It ...

guilan province is located in south and south-west of the caspian sea. guilan is one of the richest and the most humid region in the country due to suitable climate, ample rainfall and many water sources (springs, rivers, creeks,..),. despite the prevailing favorable conditions, limnological studies, especially in the mountainous regions of this province are limited. a limnological study was co...

This study examined the effects of sub- and supercritical water pretreatments on the physicochemical properties of crab shell α-chitin and its enzymatic degradation to obtain N,N'-diacetylchitobiose (GlcNAc)2. Following sub- and supercritical water pretreatments, the protein in the crab shell was removed and the residue of crab shell contained α-chitin and CaCO3. Prolonged pretreatment led to α...

Blue crab processors need packaging options for fresh and pasteurized crab meat that reduce processing and packaging costs, improve quality, safety, and shelf life, and accommodate smaller portion sizes. Traditional fresh and pasteurized crab meat containers are 16 oz polyethylene cups and 16 oz steel cans, respectively. Processors have been presented with a number of new commercial options for...

Acinetobacter baumannii has been increasingly reported as a significant causative organism of various nosocomial infections. Here we describe an outbreak of carbapenem-resistant A. baumannii (CRAB) in the ICUs of a Korean university hospital, along with a successful outbreak control program. From October 2007 through July 2008, CRAB was isolated from 57 ICU patients. Nineteen patients were diag...

Models for the diffuse Galactic continuum emission and synchrotron radiation show that it is difficult to reproduce observations of both of these from the same population of cosmic-ray electrons. This indicates that an important contributor to the emission below 10 MeV could be an unresolved point-source population. We suggest that these could be Crab-like sources in the inner Galaxy. Alternati...

Rapid industrialization along with advanced agricultural activities led to the contamination in aquatic environment with heavy metals. Heavy metals ultimately pass into human body through having aquatic animals like fish, prawn and crab. In this study, accumulation of heavy metals (zinc, copper, iron, cadmium and lead) in various organs of four commonly consumed fish (Euthynnus affinis...
