This study assessed the contribution of the apical hair cells to hearing. Guinea pigs, chinchillas and monkeys were behaviorally trained using positive reinforcement to respond to pure-tone stimuli. When a stable audiogram had been determined, each subject received one of three experimental treatments: ototoxic drug administration, low-frequency noise exposure, or the application of a cryoprobe...

in this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of a387-gr91/aisi316 steels. process parameters of the pulsed current gas tungsten arc welding (pcgtaw) including of peak current (p), background current (b), pulse frequency (f), and on time percentage (o) were chosen as the influencing factors on corrosion behavio...

[Purpose] The aim of this study was to determine the effects of high-frequency current therapy on the abdominal obesity levels of young women. [Subjects] Twenty-two women with abdominal obesity were randomly allocated to either an experimental group (n 1 = 10) or a control group (n 2 = 12). [Methods] The experimental group subjects received high-frequency current therapy for the abdominal regio...

An evaluation of the influence of sex upon cerebral atherosclerosis was carried out in 5,033 consecutive autopsies studied by a special well-standardized coding technique. A sex difference in frequency of cerebral atherosclerosis appears from the fourth to the sixth decade. During this period the percentage of female cases with no atherosclerosis lags behind the percentage of male cases by a 15...

In this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of A387-Gr91/AISI316 steels. Process parameters of the pulsed current gas tungsten arc welding (PCGTAW) including of peak current (P), background current (B), pulse frequency (F), and on time percentage (O) were chosen as the influencing factors on corrosion behavio...

BACKGROUND In this paper the real role and place of human resource (HR) in health system reform will be discussed and determined within the whole system through the comprehensive Human Resource Management (HRM) model. METHOD Delphi survey and a questionnaire were used to 1) collect HR manager ideas and comments and 2) identify the main challenges of HRM. Then the results were discussed in an ...
