With rising environmental concerns on potable water safety and eutrophication, increased media attention and tighter environmental regulations, managing animal waste in an environmentally responsible and economically feasible way can be a challenge. In this study, the possibility of using granular anammox process for ammonia removal from swine waste treatment water was investigated. A rapid dec...

Increasing numbers of hatchery-produced fish entering marine environments has caused concern over potential fitness depressions in wild populations, yet no study has addressed the likelihood of hybridisation between farmed and wild marine fish. Escape rates of Atlantic cod Gadus morhua L. from commercial net pens have been substantial and there is a risk of interbreeding between depleted local ...

The Atlantic cod (Gadus morhua) is a migratory gadid found on both sides of the North Atlantic. In the Northwest Atlantic, cod are distributed nearly continuously along the continental shelf from Greenland to North Carolina, spawning in relatively discrete, temporally stable areas, and different regions are regarded as different management units defined primarily by latitude and bathymetry (Ruz...

−A biomaterial was successfully synthesized from Plantago ovata by using an FeCl3-induced crude extract (FCE). The potential of FCE to act as a natural coagulant was tested for the pretreatment of real textile wastewater. Tests were performed to evaluate the effects of FCE quantity, salt concentration, and wastewater pH on chemical oxygen demand (COD) reduction during a coagulation/flocculation...

Europe's fishermen should stop catching North Sea cod and continue to avoid Bay of Biscay anchovies next year if the two species are to stand a chance of survival after years of chronic overfishing, scientists announced last month. Despite improvements in the numbers of northern hake, herring and mackerel, other species living in the northeast Atlantic need more time to rebuild stocks, the Inte...

cf. C. A. 30, 1179.7. The fogging and bactericidal effects of the vapor from irradiated cod-liver oil and from ozonide of olive oil were found to be due to substances liberating active O. Ozonides of olive oil, emulsions of ozonide in salt soln. and in serum, and the vapor from ozonides are all germicidal. Bacteria are not only killed by the O liberated from these oils but their growth rate may...

Although intake of multivitamin supplements is becoming increasingly popular, the relationship between intake of multivitamin supplements and incident asthma remains unclear. Prospective studies in adults with long-term follow-up are especially scarce. Our objective was to investigate the association between intake of multivitamin supplements and asthma development in Norwegian adults. We follo...

Complement fixing antibody in animals injected with heat killed tubercle bacilli in oil appears earlier in the lesion at the site of injection than in the blood serum. Complement fixing antibody in an extract prepared by suspending one part by weight of tissue from the local site in five parts of saline is in general in higher concentration than in the blood, for a period of approximately 3 wee...

−The removal of pesticides from water is a major environmental concern. This study investigates the electrochemical removal of the insecticide imidacloprid (IMD) from aqueous solutions on a boron-doped diamond (BDD) and Ta/PbO2 anodes under galvanostatic electrolysis. The influence of operating parameters, such as applied current density (50-100 mA cm), initial chemical oxygen demand COD (0) (2...
