OBJECTIVE Neonatal invasive candidiasis is associated with significant morbidity and mortality. We describe the association between invasive candidiasis and changes in use of antifungal prophylaxis, empirical antifungal therapy, and broad-spectrum antibacterial antibiotics over time. METHODS We examined data from 709,325 infants at 322 NICUs managed by the Pediatrix Medical Group from 1997 to...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...

The mel scale, relating subjective pitch in mels to physical frequency in cycles per second, is now commonly found in texts and handbooks in engineering psychology. It is usually derived from the psychophysical method known as bisection, in which the listener adjusts a variable frequency to sound half as high in pitch as a standard tone. The average subject will not, for example, adjust the var...
Auditory ERPs were recorded from eight tinnitus patients and 12 controls. Tone pips of 1000 and 2000 Hz, as well as the patient's tinnitus pitch (around 4000 Hz) were used. Controls received tone pips at 1000, 2000, and 4000 Hz. Tones were presented at 30, 36, 42, 48 and 54 dB/SL. The intensity dependence of the auditory N100 was calculated for each frequency in each group. Patients showed a st...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
Audi ological evaluation in infants should include the middle ear (immitance measures and otoscopy) and also a cochlear evaluation. Aim: To check which tympanometry tone test (226 Hz or 1000 Hz), transient otoacoustic emissions and otoscopy. Methods: Transient otoacoustic emissions were taken from sixty infants ranging from zero to four months of age. The babies were assigned to two groups of 3...
Auditory steady-state responses (ASSRs) were elicited by simultaneously presenting multiple AM (amplitude-modulated) tones with carrier frequencies of 500, 1000, 2000, and 4000 Hz and modulation frequencies of 77, 85, 93, and 102 Hz, respectively. Responses were also evoked by separately presenting single 500- or 2000-Hz AM tones. The objectives of this study were (i) to determine the cochlear ...
Supplemental irrigation under prolonged drought conditions has a key role in providing water for transpiration of rain-fed fig trees. The effect of different times and amounts of supplemental irrigation at different distances from the tree trunk on quantity and quality of Estahban rain-fed fig production was evaluated during two years. A randomized complete block design with four replications o...
