The evolution of alternative life-history strategies in fish has largely been overlooked by fisheries managers, although differences in the biology of life-history variants can have important implications for the scale and productivity of fisheries. Cod display strikingly variable colouration in the Gulf of Maine, with redand olive-coloured cod found in close sympatry. Colour types from Cashes ...

itself, and that liver, kidneys, heart, brain and sweetbreads make a useful change from a joint. As a source of vitamin A, cod-liver oil is our most valuable stand-by. The fame of cod-liver oil has undergone vicissitudes. It may have come to us from the Yikings. Belief in it waned, at times during the nineteenth century, and it became fashionable to regard extra butter as being just as good. Th...

Changes in phenotypic variability in natural populations have received little attention in comparison with changes in mean trait values. This is unfortunate because trait diversity may influence adaptive evolutionary change and population stability. We combine two unique data sets to illuminate complex trait changes in Atlantic cod along the Norwegian Skagerrak coast: (i) an annual beach seine ...

This study was carried out to assess the efficiency of a combined system consisting of up-flow anaerobic sludge blanket (UASB) reactor and down-flow hanging sponge (DHS) system for color removal from reactive dyes wastewater. The UASB reactor and DHS system were operated at HRT of 6 and 2.0 h., respectively. The results obtained indicated that, the combined system was quite effective for remova...

Ozonation was investigated as a potential post-treatment step for biologically treated landfill leachate to enhance the biodegradability and observe the influence of the initial organic matter concentration and pH. Changes in COD, UV absorption at 254 nm (UVA254) and BOD content were measured during and after ozonation, and the ozone utilisation efficiency at different conditions was calculated...

In the present work, co-immobilization of cholesterol oxidase (COD) and horseradish peroxidase (POD) on perlite surface was attempted. The surface of perlite were activated by 3-aminopropyltriethoxysilane and covalently bonded with COD and POD via glutaraldehyde. Enzymes activities have been assayed by spectrophotometric technique. The stabilities of immobilized COD and POD to pH were higher th...

ozonation was carried out for decolorization and coD removal of raw and anaerobically treated uAsb (upflow anaerobic sludge blanket) combined industrial (mainly textile) effluent in a lab-scale bubble column reactor. ozonation of anaerobic bioprocess effluent at a dose of 300 mg/h for 10 min resulted in 81% color and 75% coD removal (100 mgo3/80 mg coD) while for raw wastewater 25 min ozonation...

PURPOSE The aims of this study were to 1) compare the metabolic power demand of straight-line and change of direction (COD) sprints including 45° or 90°-turns, and 2) examine the relation between estimated metabolic demands and muscular activity throughout the 3 phases of COD-sprints. METHODS Twelve highly-trained soccer players performed one 25-m and three 20-m sprints, either in straight-li...
