The food and feeding of Flemish Cap cod are described for 5 years based on 3921 stomachs collected in the fishing grounds off the Flemish Cap, Newfoundland in summer 1989–1993. Feeding intensity was high but the prey spectrum was narrow in all years with hyperiids and redfish (Sebastes sp.) predominating. Squid and polychaetes had a high inter-annual variability. Juvenile cod diet was dominated...

Taking advantage of robust facet passivation, we unveil a laser "fossil" buried within a broad area laser diode (LD) cavity when the LD was damaged by applying a high current. For the first time, novel physical phenomena have been observed at these dramatically elevated energy densities within the nanoscale LD waveguide. The observation of the laser "fossil" is interpreted with different mechan...

The removal of COD and oil from dairy wastewater was experimentally investigated using direct current (DC) electrocoagulation (EC). In the EC of dairy wastewater, the effects of initial pH, electrolysis time, initial concentration of COD, and current intensity were examined. The COD in the aqueous phase were effectively removed when aluminum plates were used as sacrificial electrodes. The optim...

BACKGROUND This study examines emotion regulation strategies used by children of mothers with childhood-onset depression (COD) and children of never-depressed mothers (NCOD). METHODS Participants were 49 COD offspring (ages 4-7) and 37 NCOD offspring (ages 4-7) and their mothers. Emotion regulation strategies were assessed observationally during a laboratory mood induction paradigm. RESULTS...

The predatory behavior of a carnivorous marine copepod, Euchaeta norvegica Boeck, feeding on eggs and larvae of the North Atlantic cod Gadus morhua L. was examined. In the laboratory, adult females of Euchaeta norvegica did not feed on eggs. Predation rates on yolk-sac larvae and starved post-yolk-sac larvae did not vary significantly with age up to 14 days old because of little change in size ...

Some amounts of inert products are given into environment due to biological degradation of substrate in activated sludge system. The effluent of biological wastewater treatment consists of inert substrate in influent flow, soluble microbial products and non degradable or slowly degradable organic products. Soluble inert COD (SI) must be determined for discharge standards since it did not give a...

Many types of advanced oxidation processes (AOPs), namely Fenton (Fe 2+ /H2O2) with different doses, Fenton-like (UV/Fe 2+ /H2O2), photo-Fenton (Fe 2+ /H2O2/TiO2), and plasma technology have been investigated for the removal of organic matters (COD content) from landfill leachate. Fenton's oxidation was the most effective as the most effective ratio 1/10 (Fe 2+ /H2O2) which allow the COD remova...

Because codeine (COD) is eliminated primarily via glucuronidation, factors that alter COD glucuronide formation potentially affect the proportion of the dose converted to the pharmacologically active metabolite morphine. Thus, in vitro-in vivo extrapolation approaches were used to identify potential drug-drug interactions arising from inhibition of COD glucuronidation in humans. Initial studies...

In this study, we investigated the efficiency of dissolved methane (D-CH(4)) collection by degasification from the effluent of a bench-scale upflow anaerobic sludge blanket (UASB) reactor treating synthetic wastewater. A hollow-fiber degassing membrane module was used for degasification. This module was connected to the liquid outlet of the UASB reactor. After chemical oxygen demand (COD) remov...
