โœฆ Synopsis

The heat transfer across metallic contacts in vacuum is studied in the temperature range from 300 to 6 K, An enthalpy of 35 MJ is removed from two large copper rings by a cooling device built into a levitated superconducting quadrupple plasma physics device. Above 50 K the contact conductance has a value of 3.5 W per K I, which is found to be independent of temperature. Between 5.5 and 20 K the conductance varies as shown by the following empirical relation: C (W K-I) = 4 x 10 -4 x T 2"8 (where T is in K).

Inhibition of immobilized alkaline phosphatase by several metal ions and EDTA was studied in a single-channel flow-injection system. The enzyme was immobilised on controlled pore glass. The same enzyme preparation was used for three months. The inhibition by the tested compounds is reversible, the i
