Localization of Cofibration Categories and Groupoid C∗C^*-algebras

We prove that relative functors out of a cofibration category are essentially the same as relative functors which are only defined on the subcategory of cofibrations. As an application we give a new construction of the functor that assigns to a groupoid its groupoid $C^*$-algebra and thereby its topological $K$-theory spectrum

Satellite remote sensing for ice sheet research

Potential research applications of satellite data over the terrestrial ice sheets of Greenland and Antarctica are assessed and actions required to ensure acquisition of relevant data and appropriate processing to a form suitable for research purposes are recommended. Relevant data include high-resolution visible and SAR imagery, infrared, passive-microwave and scatterometer measurements, and surface topography information from laser and radar altimeters

Theological Education in the Third World: An Appraisal and Recommendation

Theological education in the third world is coming of age, but not without growing pains. The church overseas has been experiencing tremendous growth in recent years and is becoming more mature. Because of this, the demand for well-trained leaders has increased remarkably. In many areas of the world, the established theological schools have not been able to supply the necessary numbers of trained pastors required by the churches. This is further aggravated by the fact that not all of the graduates of theological and Bible schools actually become pastors. This phenomenon has precipitated a serious and necessary re-evaluation of the whole system of theological education and provoked some observers to criticize it as an impractical Western pattern. A cry for innovative reforms is heard from many sectors. It was in this context that the present study was undertaken

The Impact of Ozone on the Survivability of Brine Shrimp

Ozone (03) is a strong oxidizing agent that is routinely used as a disinfectant in water treatment for bacteria, viral infections, and al­gae. Brine shrimp are used in many aquaculture environments as fish food. Typically the brine shrimp eggs are hatched on site and fed to the fish stock after maturation. Brine shrimp are capable of transporting microbes into the fish stock. In order to eliminate the detrimental effects of infections from this process we ran a series of mortality tests by applying ozone to the brine shrimp. The time du­rations of ozone ranged from 5 min to 24 hours. A second set of experiments expose the brine shrimp directly with ozone over their life cycle (2 months). Our results demonstrate that ozone can be applied directly to the brine shrimp increasing their survivability
