trials with bull trout – weeks postchallenge to determine whether increasing the challenge dose would affect swimming endurance and hematocrit. In those tests, bull trout with clinical signs of disease and those exposed to the highest challenge doses had significantly reduced swimming endurance compared with unchallenged control fish. Fish hematocrit levels measured at the end of all swimming endurance tests varied among species and between test temperatures, and patterns were not always consistent between challenged and control fish. for up to min enhanced the mass-normalized adsorption at  . of all test compounds, especially the weak acids and bases, by up to -fold. Both general and specific effects were identified. The general effect results friendship flamingos beer party all over print hawaiian shirt from “reaming” of pores by the oxidative removal of pore wall matter andor tarry deposits generated during the pyrolysis step. Reaming creates new surface area and enlarges nanopores, which helps relieve steric hindrance to adsorption. The specific effect results from creation of new acidic functionality that provides sites for the formation of very strong, charge-assisted hydrogen bonds with solutes having comparable pKa. The CAHB hypothesis was supported by competition experiments and the finding that weak acid anion adsorption increased with surface carboxyl content, despite electrostatic repulsion from the growing negative charge. The results provide insight into the effects of air oxidation on pollutant retention. and ACFs. This behavior was explained by an increase in the available number of free sites, previously occupied by oxygen and now available for SO adsorption.

The use of nitrogen-containing functional groups on ACFs of proper pore size shows promise for further increasing SO adsorption capacities. Knowledge of the relationship among the number of free sites, pore size, and surface chemistry on corresponding SO adsorption should lead to the development of more efficient adsorbents prepared from either coal or ACFs. Although the data were less conclusive for fall- than spring-sampled fish, they do suggest spawner effects were also generally positive during fall, soon after salmon spawned. In a follow-up analysis where growth rate and energy density were modeled as a function of δN enrichment, results suggested that both increased with MDN assimilation, especially in juvenile coho salmon. Our results support the importance of salmon runs to the nutritional ecology of stream-dwelling fishes. soil. It could be shown that phenols and furfurals, which were removed from the hydrochar after washing by to did not affect the germination rate and the root length of the cress plants. The lowest germination rate and root length were found in the soil control, the highest in the non-washed hydrochar treatment, indicating a fertilization effect and growth stimulation of cress salad by hydrochar. If this result can be confirmed for other target and non-target organisms in future studies, a new strategy for the production of growing media may be developed. and non-condensable, combustible gases. The residence time is a function of gas flow rate and the initiating temperature is likewise a function of the gas flow rate, varying therewith. A controlled initiating temperature range of about ith corresponding gas flow rates to maximize oil yield is disclosed. to begin burning under lower temperature. The ignition index was increased, respectively, and the combustion characteristic index was increased respectively, b In addition, two kinetic models were adopted to calculate the kinetic parameters in different stage of combustion processes. The results showed that with FeO or CaO addition, the activation energy at second stage decreases from . KJmol to . KJmol and . KJmol, respectively. There are no obvious decreases at the third stage of samples combustion process. Fast pyrolysis characterization of three dry manure samples was studied using a pyro er.

Functional group chemistry determined by NMR shows that the aromaticity of the product increases as a function of temperature whereas the amount of O-alkylic compounds
