Tittel/Title: Scenario-C: The cod predation model. Sammendrag/Abstract: The Scenario C project aims at a dynamic minimal realistic model for capelin, herring, cod, harp seals and minke whales in the Barents Sea and for herring in the Norwegian Sea. This report is an attempt to estimate a consumption function for cod from estimated monthly abundances of capelin, herring and younger cod in region...

The Baltic Sea ecosystem is hypothesized to have undergone a regime shift during the last 3 decades, altering its functioning and the composition of its zooplankton and fish communities. The new stable state has been considered as 'cod hostile' due to reduced spawning success in cod, as well as increased predation on and declining food sources for cod larvae. Nonetheless, the eastern Baltic cod...

The effect of the food/microorganisms (F/M) ratio and dissolved oxygen (DO) concentration in sequencing batch reactors (SBRs) on the microbial activity has been examined. One of the SBRs was fed with synthetic wastewater containing inorganic carbon compounds (COD/N ratio 0.7 g COD/g N). To the other SBR, both inorganic and organic carbon was supplied leading to 6.9 g COD/g N. The F/M ratios in ...

The aim of the present work was to evaluate the effect of the carbon/nitrogen (COD/N) ratio on the implementation of technologies treatment of swine wastewater (SW). The results show that the chemical processes are efficient for N removal (up to 99%) contained in SW when COD/N ratio is higher than 10 g/g. However, these processes are inefficient in COD removal (< 33%). COD/N ratio parameter is ...

A syntax-correcting CIF parser, COD::CIF::Parser, is presented that can parse CIF 1.1 files and accurately report the position and the nature of the discovered syntactic problems. In addition, the parser is able to automatically fix the most common and the most obvious syntactic deficiencies of the input files. Bindings for Perl, C and Python programming environments are available. Based on COD...

A membraneless bioelectrochemical system - rotatable bio-electrochemical contactor (RBEC) consists of an array of rotatable electrode disks was developed to convert the chemical energy from wastewater organics (acetate) directly into electricity. Each rotatable electrode disk had an upper-air exposing and a lower-water submerging halves. Intermittent rotation (180°) enabled each halve to altern...
