This research is devoted to investigate relationship between both Ultrasonic Pulse Velocity and Rebound Number (Hammer Test) with cube compressive strength also study the effect of steel reinforcement on these relationships. A was carried out 32 scale model reinforced concrete elements. Non destructive testing campaign (mainly ultrasonic rebound hammer tests) made same About 72 cubes (15 X 15 X...

In order to detail the characteristics of end-point (EPN) and rebound nystagmus (RN), two series of experiments were performed with infrared oculography for measurement of horizontal eye movements. Experiment 1 consisted of EPN recordings during sustained lateral gaze (40 degrees and 50 degrees) in 20 normal subjects. Experiment 2 consisted of recordings of RN in 5 normal subjects. Nine of 20 s...

The mechanism of postinhibitory rebound increase in GH secretion was studied in 5 normal and 7 acromegalic subjects. Both normal and acromegalic subjects showed prompt GH decreases during the infusion of somatostatin (500 micrograms/75 min) (% decrease: 69.1 +/- 10.4 vs. 73.9 +/- 6.5) and rebound rises after its termination. The rebound rises occurred more promptly and markedly in normal contro...

Bezoar formation is cited to be the cause of delayed absorption of aspirin in overdose of enteric-coated aspirin preparation. However, such phenomenon from oral overdose of regular aspirin preparation has not been clearly demonstrated in human. The use of multiple-dose activated charcoal (MDAC) in salicylate poisoning remains controversial. We report a case of regular-preparation salicylate poi...

Wang and Brown8 were the first to describe the terminal rebound and, except for the fact that it is seen after stimulation of purely muscular nerves, the present experiments confirm theirs in essence. It is agreed that afferent C fibers must be active for the effect to appear. Another condition seems to be that the C fiber reflex must fall during the course of the A fiber reflex; otherwise, the...
