A Substitute for Beerwort as a Yeast Medium in the Bacteriology Laboratory

Ordinary beerwort, the usual medium in the past for yeast culture in Bacteriology laboratories, has become increasingly difficult to obtain. The manufacture of beerwort in the laboratory is a tedious process and the product is variable and often unsatisfactory for good yeast growth

An empirical investigation of the anxiolytic and pain reducing effects of music

This article reports two empirical experiments investigating the anxiety and pain reducing effects of listening to music via personal stereo following surgical procedures involving general anaesthetic. Both experiments involved participants selecting music of their own choice. In Experiment 1, following minor surgery on the foot, 20 participants in an experimental group listened to music while 20 participants in a control group did not. Results indicate that the music group felt significantly less anxiety than the control group. No differences in pain measurements between the two groups were found. Experiment 2 involved a music listening group of 30 females and a no music control group of 28 females. Both groups underwent a total abdominal hysterectomy. Postoperative measures of pain, anxiety and patient-controlled analgesia were taken. No differences between the groups were obtained on these measurements. The results of both experiments are discussed with reference to subjective responses to musical stimuli
