Understanding the mechanisms of spatial population dynamics is crucial for the successful management of exploited species and ecosystems. However, the underlying mechanisms of spatial distribution are generally complex due to the concurrent forcing of both density-dependent species interactions and density-independent environmental factors. Despite the high economic value and central ecological...

This investigation proved that respirometry combined with sequencing batch reactor (SBR) could be an effective way for the removal of COD in tannery wastewater. Measurement of oxygen uptake rates (OUR) and corresponding COD uptake rates showed that a 12-h operating cycle was optimum for tannery wastewater. The removal of COD by degradation was stoichiometric with oxygen usage. A plot of OUR val...

The wastewater treatment with a two-phase expanded granular sludge bed (EGSB) system for anaerobic degradation of acetate, benzoate, terephtalate and p-toluate from purified terephtalic acid (PTA) production was studied. The feasibility and effectiveness of the system was evaluated in terms of organic oxidation by chemical oxygen demand (COD), gas production, bacterial adaptability and stabilit...

This work focused on glycerol exploitation for biogas and hydrogen production. Anaerobic digestion of pure glycerol was studied in a continuous stirred tank reactor (CSTR), operated under mesophilic conditions (35C) at various organic loading rates. The overall operation of the reactor showed that it could not withstand organic loading rates above 0.25 g COD L d, where the maximum biogas (0.42 ...

A new integrated Bayesian framework for making quantitative assessments, predictions, and risk analyses of shrimp (Pandalus borealis) stock development is constructed. A biomass dynamic model, based on the logistic function but including an explicit term for cod predation, suggests that the quantity of shrimp consumed by cod could equal that taken by the fishery. The model proved superior to an...

BACKGROUND This study examined preschoolers' emotion regulation (ER) strategies and the association with temperament, maternal interactive style, and maternal history of childhood-onset depression (COD). METHODS Participants were 62 children and their mothers, 37 of whom had mothers with COD. Children's ER was assessed using a disappointment paradigm; temperament assessment also was laborator...

We investigated the conventional characterisation and biological treatability of wastewaters of the “Izmit Industrial and Domestic Wastewater Treatment Plant”. Respirometric procedures were carried out for the experimental assessment of organic contents of wastewater. The mean value of total COD was 1201 mg·l-1 and varied within a wide range of 580 to 1822 mg·l-1 for the 14 different influents....

Cemento-osseous dysplasia (COD) is a disease characterized by the replacement of normal bone with fibrous tissue and metaplastic bone, and occurs in the tooth-bearing areas of the jaws. It is usually asymptomatic and often found incidentally on radiographs. Herein, we report a rare case in which florid COD (FLCOD) and focal COD (FOCOD), two different forms of COD, coexisted in the maxilla of a ...

The labile compound [RuCl2(NCCH3)2(cod)], an alternative starting material to [RuCl2(cod)]n for the preparation of ruthenium(II) complexes, has been prepared from the polymer compound and isolated in yields up to 87% using a new work up procedure. The compound has been obtained as a yellow solid without water of crystallization. Complexes [RuCl2(NCR)2(cod)] spontaneously transform into the dime...

The reaction of [Ir(IMes)(COD)Cl], [IMes 1⁄4 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene, COD 1⁄4 1,5cyclooctadiene] with pyridazine (pdz) and phthalazine (phth) results in the formation of [Ir(COD)(IMes)(pdz)]Cl and [Ir(COD)(IMes)(phth)]Cl. These two complexes are shown by nuclear magnetic resonance (NMR) studies to undergo a haptotropic shift which interchanges pairs of protons within th...
