Studies on disinfection of clinical thermometers. II. Oral thermometers from a tuberculosis sanatorium.

A study was made of the chemical disinfection of oral thermometers used by patients with active pulmonary tuberculosis. Only 10% of these thermometers were found to be contaminated with acid-fast bacilli. Because of this small number, the use of a phenol coefficient type test with Mycobacterium tuberculosis was suggested as an alternative method for evaluating tuberculocidal activity. These dat...

Nuclear Thermometers

In intermediate energy nuclear collisions (E/A~50MeV), the nuclei collide and compress, forming what is called a compound nucleus. As the compound nucleus cools and expands, it breaks apart into multiple nuclei in a process called multi-fragmentation. These fragments then begin to cool by emitting small nuclei. The final products of decay are then observed in detectors. The populations of nucle...

Thermometers for low temperature Magic Angle Spinning NMR.

The measurement of temperature in a Magic Angle Spinning NMR probe in the temperature range 85-300K is discussed. It is shown that the shift of the (119)Sn resonance of Sm(2)Sn(2)O(7) makes a good thermometer with shift being given by delta=223 - 9.54x10(4)/Tppm and a potential precision of better than 0.5K over the entire temperature range. The sensitivity is such (e.g. 4.2ppm/K at 150K) that ...
