Die e-Shuttle-Katalyse ist ein vielversprechendes Werkzeug, um funktionelle Gruppen zwischen Molekülen hin und her zu übertragen, zwar über einen aufeinanderfolgenden Mechanismus der gepaarten Elektrolyse. Ein seltenes Beispiel für eine Shuttle-Heterodifunktionalisierung zur Übertragung zweier unterschiedlicher funktioneller β-Halogensulfiden ungesättigten Kohlenwasserstoffen zeigen Siegfried R...

Constructions of Escherichia coli-spirochete shuttle vectors are based on naturally occurring plasmids, broad host range plasmids or bacteriophages. This review primarily focuses on genetic tools for Treponema denticola which is associated with periodontal diseases. The T. pallidum FlaA protein, E. coli beta-galactosidase, and the green fluorescent protein were successfully expressed in T. dent...

The digital elevation model derived from SAR Interferometry is prone to atmospheric, penetration into soil medium, system noise and decorrelation errors. Eight ASAR images are selected for this study which have unique data set forming 7 InSAR pairs with single master image. It is expected that all the DEMs should have the same elevation values spatially with in the noise limits. However, they d...

[1] The Shuttle Radar Topography Mission produced the most complete, highest-resolution digital elevation model of the Earth. The project was a joint endeavor of NASA, the National Geospatial-Intelligence Agency, and the German and Italian Space Agencies and flew in February 2000. It used dual radar antennas to acquire interferometric radar data, processed to digital topographic data at 1 arc s...

Indonesian peatlands are one of the largest near-surface pools of terrestrial organic carbon. Persistent logging, drainage and recurrent fires lead to huge emission of carbon each year. Since tropical peatlands are highly inaccessible, few measurements on peat depth and forest biomass are available. We assessed the applicability of quality filtered ICESat/GLAS (a spaceborne LiDAR system) data t...

This short paper describes and analyzes the results of a methodology that allows to conflate existing Digital Elevation Models with a sample set of elevation points in order to obtain more accurate results on modeling elevation information. The set of elevation points has higher vertical accuracy than the DEM and it is used the geostatistical procedure, known as kriging with an external drift, ...

Several studies have indicated that glaciers in the Qinghai-Tibet plateau are thinning, resulting in reduced water supplies to major rivers such as the Yangtze, Yellow, Lancang, Indus, Ganges, Brahmaputra in China, and south Asia. Three rivers in the upstream of Yangtze River originate from glaciers around the Geladandong snow mountain group in central Tibet. Here we used elevation observations...
