Dieta.—Male Wistar rats were placed on a semi synthetic diet at weaning, and the food consump tion of each was measured. A week later each rat was paired with one of equal body weight and food consumption. At this time one rat of each pair was designated as the experimental rat which would receive a tumor transplant; the other rat, his pair fed control, consumed the amount of diet eaten by th...

The technical feasibility of geothermal power production will be demonstrated in the geothermal research wells Groß Schönebeck using a borehole doublet. This task includes safeguarding the thermal fluid cycle and the optimisation of energy conversion technology at the surface. In order to complete the Enhanced Geothermal System, three massive hydraulic stimulations were performed injecting a to...

The air quality design value is the mathematically determined pollutant concentration at a particular site that must be reduced to, or maintained at or below the National Ambient Air Quality Standards (NAAQS) in order to assure attainment. The design value may be calculated based on ambient measurements observed at a local monitor in a 3-year period or on model estimates. The design value, howe...

This paper describes the development of a v ision-based finger track ing system for media art; the system utilizes an infrared camera and a Kalman filter to accomplish this finger recognition image processing technology . The system is stable and fast, and is able to recognize not only gestures but also the speeds of gestures. Our work , called the "Narrative Hand", switches movies to show the ...

This is a rare syndrome, characterised by an acute, life-threatening, non-inflammatory encephalopathy and fatty degeneration of the liver with minimal or no clinical signs of liver involvement. In classic Reye's syndrome, there is a severe but self-limiting disturbance of mitochondrial structure and associated enzymatic disturbances usually lasting about six days. This is accompanied by an inte...

Environmentally cued plasticity in hatching timing is widespread in animals. As with later life-history switch points, plasticity in hatching timing may have carryover effects that affect subsequent interactions with predators and competitors. Moreover, the strength of such effects of hatching plasticity may be context dependent. We used red-eyed treefrogs, Agalychnis callidryas, to test for la...

We present two heuristics based on constraint technology that solve the problem of generating air traffic management contingency plans, which are used in the case of a catastrophic infrastructure failure within EUROCONTROL, the European Organisation for the Safety of Air Navigation. Of the heuristics presented, one is based on constraintbased local search and tabu search, and the other one is a...
