Abstract: This invention provides a live attenuated human rotavirus vaccine and a method for the preparation of such a vaccine. The method overcomes problems experienced hitherto in the growth of human rotaviruses, by the use of larger quantities of inocula at the initial growth stage and subsequent passages.

Abstract: A novel and improved method to detect indirectly a temperature of an object employing nuclear magnetic resonance techniques (NMR). The method involves obtaining an NMR spectrum to determine chemical shift, relaxation times, spin-spin couplings or quadrupole couplings for an element of a compound having at least one conformational isomer wherein the compound is influenced by a temperature of the object. Uniquely, the present invention may detect temperature in the body of an animal. Further, the present invention discloses a novel method to determine and monitor thermal physiological states in an animal as well as determine and monitor thermal states in an object. Because of the unique and advantageous non-invasive, non-destructive and non-ionizing properties, the present invention may be employed in an object or animal continuously.
