Tension of the forehead increases as a response to unpleasant stimuli. In three experiments EMG activity in corrugator muscle was measured to test this response as an indicator of noise annoyance. In Exp. 1 (n = 24) monotonic sound level-response functions were obtained for four levels of 100- and 1000-Hz tones. In Exp. 2 (n = 20) recordings were made(More)
The Gram-positive bacterium Geobacillus stearothermophilus ATCC 12980 is completely covered with a two-dimensional crystalline monolayer composed of the S-layer protein SbsC. In order to complete the structure of the full-length protein, additional soluble constructs containing the crucial domains for self-assembly have been successfully cloned, expressed(More)
