PURPOSE/OBJECTIVES To examine the relationship between hope and fatigue (intensity, duration, and interference) in newly diagnosed patients with cancer receiving chemotherapy. DESIGN Cross-sectional and correlational. SETTING Oncology outpatient clinics of two medical centers in northern Taiwan. SAMPLE 182 patients diagnosed with various types of solid tumors in the previous six months an...
Aim: In this naturalistic study the aim was to examine the impact on seizure duration of stimulus intensity, previous treatments (during the first course of ECT), age, gender, and electrode placement. Method: The database of the ECT Service of the Royal Hobart Hospital was examined for the 15 years ending in 2010. First courses of ECT were identified in which the stimulus intensity was not alte...
abstract this research evaluates climate change effects on drought severity in the region of gharesou, iran. the standardized precipitation index (spi) has been used for estimation of drought severity. a geographical information system is applied for calculating the mean areal precipitation time series from 11 meteorological stations, in and out of the area for the hydrological period jan 1971-...
we have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. the present experiment was undertaken to find out the best duration for treatment. a complete transverse fracture was made in the right radial bones of21 adult male rabbits by a stanley knife. the animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental gro...
اندازه گیری شدت صدا (sound intensity) برای تشخیص منابع نویز در یک مجموعه متراکم از قطعات در حال کار و مرتبط با یکدیگر در خودرو کابردهای فراوانی دارد. خوشبختانه بر اساس تلاشهای محققان [ j.y.chunf] and [f. j. fahy] سیستمی طراحی شده که میتوان بدون استفاده از اتاقک آکوستیک شدت صوت را با دقت خوبی در محیط های آزاد اندازه گیری کرد.
1. This investigation has been concerned with an analysis of brightness discrimination as it is influenced by the duration of DeltaI. The durations used extend from 0.002 second to 0.5 second. 2. DeltaI/I values at constant intensity are highest for the shortest duration and decrease with an increase in duration up to the limits of a critical exposure time. At durations longer than the critical...
Indoor diffuse optical intensity channels are bandwidth constrained due to the multiple reflected paths between the transmitter and the receiver which cause considerable inter-symbol interference (ISI). The transmitted signal amplitude is inherently non-negative, being a light intensity signal. All optical intensity root Nyquist pulses are timelimited to a single symbol interval which eliminate...
A knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. Hydrologists have always been concerned about Depth- Area- Duration (DAD) for a specific storm in a watershed. An intense storm occurred on June 6, 1992 which claimed some lives in parts of Mashhad, Khorasan Province, Iran. Data of rainfall depth at 29 raingauge stations around the city and ...

a study on biocompatibility of three endodontic sealers: intensity and duration of tissue irritation
introduction: several studies have evaluated the inflammatory reaction triggered by epiphany (eph), a contemporary endodontic sealer. however, they used conventional parameters, which need additional analysis to better understand the reactions induced by this sealer compared to other traditional sealers. methods and materials: the intensity and time span of tissue irritations for three endodont...
