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...

DNA vaccines are administered in the form of plasmid DNA (pDNA) carrying a strong promoter and the gene of interest. In this study we investigated the tissue distribution, cellular uptake and the fate of intravenously (i.v.) and intramuscularly (i.m.) injected pDNA in Atlantic cod (Gadus morhua L.). The anatomical distribution of pDNA was determined using both morphological and radiotracing met...

Educational ontologies are classified into οnthologies of Student Learning Outcomes (SLO), Learning Objects (LO) and Cognitive Domains (CoD). In contrast to the conceptualization and implementation of SLO and LO ontologies, based on standards available in the literature, the CoD ontologies involve subjectivity derived from the analysis of basic concepts of each CoD and relational expressions th...

We relate two diierent approaches for the speciication and veriication of hybrid systems. The rst one is logic-based and uses the framework of the Calculus of Durations (CoD), the second one is automata-based and uses algorithmic analysis techniques for hybrid automata. Fragments of CoD have been identiied in 13, 19] for the description of control systems and their requirements. We mainly show ...
