ROACH accelerated BLAST
Reconfigurable computing, in recent years, has been taking great strides in becoming part of mainstream computing largely due to the rapid growth in the size of FPGAs and their ability to adapt to certain complex applications efficiently. This dissertation investigates the reuse of application …

The mobility of radiocesium and plutonium in Roach Lake in southern Nevada
… I through V) were selected in a dry lake called Roach Lake located in Ivanpah Valley about 41 miles west of Las Vegas, Nevada. The samples were analyzed for Cs-137 and other gamma emitting radionuclides using high purity germanium detectors. the plutonium analysis was performed, after chemical …

Factors affecting the growth and recruitment of cyprinid populations of the River Wensum, Eastern England, with specific reference to roach Rutilus rutilus (L.).
1. The roach Rutilus rutilus population of the River Wensum, Eastern England, has long been the topic of deliberation amongst the angling community due to a perceived decline in their catches since the 1970s. Analysis of fish population survey data collected by the Environment Agency and its …

The response of German cockroaches to commercial toxic baits and their potential to develop resistance
Multiple strains of German cockroaches, Blattella germanica, were exposed to four different toxic baits. The baits used were Roach Ender, Whitmire gel bait (not commercially available), Stapleton’s Magnetic Roach Food and Baygon. For each bait, strains varied in respect to bait consumption, percent …

The ecology of larval and juvenile fishes in lowland rivers, with particular emphasis on foraging
… to daylight. Gut fullness of 0+ juvenile roach and perch increased at night, but there was a reduction in gut fullness at night for larval roach and perch, suggesting a switch in feeding behaviour during ontogeny that was also evident in electivity indices and prey availability. Seasonal …

Predicting the ecological consequences of river management for a riverine cyprinid fish.
… to predict the distribution and growth of roach (Rutilus rutilus), a common, generalist, freshwater fish; known to be typically dominant in heavily modified rivers. Such a model seeks to build on current management models and practices, with emphasis on improving recruitment of juvenile …

The role of aquatic macrophytes in the availability of food for young fish
… associations were found. The O+ roach diet contained microcrustacea from the open water and the weedbeds (50% numerically and 68% by weight). B. longirostris (open) was the preferred food but if not abundant the roach switched to pulchella (weed). Feeding was determined by prey …

Relationships between population density feeding and growth of the roach (Ratilus ratilus, L. 1758) and other coarse fish in a gravel-pit lake in Southern England
Gravel-pit lakes are an increasingly common feature of our landscape, particularly on the flood plains of rivers close to large urban or industrial areas e. g. the Thames Valley (see Fig. 1). When sand and gravel are removed from below the water table, lakes are produced by seepage into the …

The efficacy of back calculation methods for determining length at age data and the use of such data to determine growth standards, national growth patterns and recruitment dynamics of roach (Rutilus rutilus (L.)), dace (Leuciscus leuciscus (L.)) and chub (Leuciscus cephalus (L.)) in UK rivers
… growth curves were originally produced for roach, dace, chub and bream (Hickley and Dexter 1979) and later expanded to include pike (Hickley and Sutton 1984). Habitat rehabilitation (Quinn 1994) and water quality improvements (Environment Agency 2001; 2006) are among a number of factors that …

A comparison of growth rates of coarse fish in gravel-pit lakes in south-east England and of population structure in selected lakes
… are very variable, the commonest species being roach (Rutilus rutilus L.), bream (Abramis brama L.), tench (Tinca tinca L.), perch (Perca fluviatilis L.) and pike (Esox lucius L.). There was no apparent correlation between fish growth rate and age, size or any other measured parameter of a lake. …

Community ecology and population dynamics of the European native oyster (Ostrea edulis) in Essex, UK: A baseline for the management of the Blackwater, Crouch, Roach and Colne Estuaries Marine Conservation Zone
… the designation of the Blackwater Crouch Roach and Colne Estuaries Marine Conservation Zone (hereafter BCRC.MCZ) in 2013, there is now a legal obligation to “protect and enhance” remaining stock of the European native oyster, Ostrea edulis. Despite this, little is known about the current …

Inter-specific hybridization in the fish family Cyprinidae

The effects of certain age factors on the response of the German cockroach to insecticides
Two age factors were studied: the age of the roach at the time of testing, and the age of the female parent at the time reproduction occurred. Age groups from 1-3 days to 25-28 days were used to test the first factor and the first three egg eases were used to test the latter. Age was found to be a …
