In order to accurately determine Avogadro's constant, N/sub A/, the volume of a nearly perfect single-crystal silicon sphere of 1 kg mass and about 90 mm diameter is to be measured with a relative uncertainty less than 10/sup -7/. For this purpose,a

For the new determination of Avogadro's constant, N/sub A/, one part of the measuring task consists in the high accuracy determination of the volume of a silicon sphere with a mass of 1 kg and a diameter of about 90 mm. An interferometer with spheric

A digital piezo system comprises a PZT and a capacitive sensor combined in a single unit. The desired displacement can be achieved by simply inputting the displacement value into the software. However, when target value of /spl lambda//8 was input to

The hypothesis that there is prostaglandin-mediated hypercalcaemia associated with the Walker carcinosarcoma in the rat was tested by measuring PGE production during the development of the hypercalcaemia, and determining the effects of inhibition of
