This paper presents the treatment of Acid green V by an electrochemical oxidation using Ti/RuO2 IrO2 TiO2 as anode and cathode and NaCl as supporting electrolyte in a tubular flow reactor under continuous single pass process. During the electrolysis, COD reduction, color removal, and energy consumption were investigated under different flow rates and current densities. The experimental results ...

The coefficient of determination (CoD) has significant applications in genomics, for example, in the inference of gene regulatory networks. We study several CoD estimators, based upon the resubstitution, leave-one-out, cross-validation, and bootstrap error estimators. We present an exact formulation of performance metrics for the resubstitution and leave-one-out CoD estimators, assuming the dis...

14 Kildin cod is a small landlocked population of Atlantic cod reproductively isolated from 15 marine counterparts for around 1500-2000 years. The Kildin cod lives in a shallow 16 meromictic lake in the five-meter intermediate layer of water with sharp gradients of oxygen 17 and salinity. The cod had an effective population size of around one hundred individuals and 18 evolved unique physiologi...

Anaerobic treatment is applied extensively of removal of organic pollutants (COD) from wastewater. It is more competitive than aerobic treatment in applications where the quantity of COD to be removed is large. The major fraction of COD is converted to useful methane gas, and only a small fraction becomes waste sludge. The COD loading rate of anaerobic reactors is higher than that of aerobic re...

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...
