The function of precipitation intensity-duration-frequency is needed for the planning and design of water resource projects. Short duration precipitation data are hardly available. However the total hourly-recorded available precipitation data for different parts of NWFP from different departments have been collected and analyzed for the present study. The data from WAPDA is found to be more au...

PURPOSE The purpose of this study was to validate the accuracy of self-reported (SR) training duration and intensity distribution in elite endurance athletes. METHODS Twenty-four elite cross-country skiers (25 ± 4 y, 67.9 ± 9.88 kg, 75.9 ± 6.50 mL · min-1 · kg-1) SR all training sessions during an ~14-d altitude-training camp. Heart rate (HR) and some blood lactate measurements were collected...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...

Previous research indicates that response force increases with stimulus intensity in simple reaction time (SRT) tasks. This result contradicts the common view that the perceptual system activates the motor system via a punctate go signal of fixed size. An elaborated view assumes that the size of the go signal depends on stimulus intensity so that more intense stimuli yield more forceful respons...

This paper aims to investigate the effects of motion duration on the structural seismic demands, seeking potential correlations between motion durations and structural responses at several seismic intensity levels. Three seismic intensity levels with 100years, 475years, and 2475years earthquake return periods (RPs) are first considered for correlation computations. Spectrally matched ground mot...

introduction: excessive olivo-cerebellar burst-firing occurs during harmaline-induced tremor. we hypothesized that antiglutamatergic agents would suppress harmaline tremor. from this point of view, the aim of current study was to investigate the effects of riluzole on harmaline-induced tremor in rat. material and methods: four groups of wistar rats weighing 80–100 g were injected with harmaline...

Two experiments were performed to investigate differential effects of practice and signal intensity on auditory duration discrimination. In Experiment 1, an adaptive forced choice procedure was used to elucidate the effects of practice. Two base durations of either 50 ms and 1,000 ms were employed. As a measure of performance, the difference limen (DL) was computed. Twenty naive volunteers perf...

The purpose of this research is to analyze heat waves characteristics in the warm period of the year as a climatic hazard in Iran. In this study, the daily maximum temperature is taken at 44 synoptic stations during the period 1981-2010. These temperature values were used to extract the intensity, frequency and duration of heat waves using percentile thresholds of 90, 95, and 98. The results sh...

Introduction: The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study.Materials and Methods: Participants were 10 adult patients between 50-80 years with prolifer...
