We present a study of a group of long period waves excited by theearthquakes of Friuli (Italy) in 1976 and recorded between longitudinaland transverse body waves by Long-period seismographs at epicentraldistances up to about 3 000 Km. The spectral analysis has permitted usto determine periods of the main phases which make up the wave group.In regard to the longer period phase, which appears first in the recordings,the velocity obtained by the dromochrones equals 8.4 Km/s. The groupvelocity is instead 7.4 Km/s. Such phases have been considered as beinglongitudinal channel waves in the astenosphere. Such hypothesis explainsthe inconsistencies which had appeared in previous studies on channelwaves in the astenosphere.

The microdilution checkerboard technique was utilized to distinguish synergistic activity between tobramycin and four beta-lactams: piperacillin-tazobactam, ticarcillin-clavulanate, ceftazidime, and ceftriaxone. Beta-lactam-aminoglycoside combinations were tested against 75 clinical isolates of Pseudomonas aeruginosa, Acinetobacter baumanii, Citrobacterfreundii, Serratia marcescens, and Enterobacter cloacae. Despite in vitro susceptibilities, all isolates demonstrated either synergism or indifference; no antagonism was observed. Against pathogenic gram-negative nosocomial isolates, a greater percentage of synergy was consistently observed with combination regimens containing tobramycin and piperacillin-tazobactam or ticarcillin-clavulanate than with the cephalosporin-containing regimens.
