The Western clawed frog, Xenopus tropicalis, is a highly promising model amphibian, especially in developmental and physiological research, and as a tool for understanding disease.It was originally found in the West African rainforest belt, and was introduced to the research community in the 1990s.The major strains thus far known include the Nigeri
The Klett research site was developed in conjunction with the new E6 developments south of Trondheim, Norway.The site comprises non-sensitive clay to about 6 m to 8 m and quick clay with significant silt lenses below this down to at least 30 m.The materials encountered are typical of the marine clays found in Scandinavia and North America.Classical
Acceleration sensors built into smartphones, i-pads or tablets can conveniently be used in the physics laboratory.By virtue of the equivalence principle, a sensor fixed in a non-inertial reference frame cannot discern between a gravitational field 100w products and an accelerated system.Accordingly, acceleration values read by these sensors must be
