Potential Carbon

In groundwater, the lack of carbon source is a key problem of in-situ denitrification. It is very important to choose appropriate solid carbon-source materials. In this work, wheatstraw and sawdust were selected as potential carbon sources to evaluate the performance for in-situ biological denitrification in groundwater by column experiments. The results showed that sawdust was a suitable corbon source with less release of nitrogen compounds and relatively stable release of organic carbon, compared with wheatstraw, and was applicable for further use as a filling material in in-situ ground water bioremediation.

As the lack of carbon source is a key problem of in-situ denitrification in groundwater, choosing appropriate solid carbon source materials is very important. In this study, wheatstraw and sawdust were selected as potential carbon sources to evaluate the performance for in-situ biological denitrification in groundwater by three laboratory-scale column experiments operated at a flow rate of 2.0 cm3/min for 78 d. The results showed that sawdust was a suitable carbon source with less release of nitrogen compounds and relatively stable release of organic carbon, compared with wheatstraw, and was applicable for further use as a filling material in in-situ groundwater bioremediation.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
