In this paper, we simulated series arc on electric heaters, vacuum cleaners and incandescent lamps controlled by a dimmer to analyze the characteristics of series arc that causes electric fires. A high pass filter (HPF) was designed to detect arc signal only. The HPF consists of 2-stage coupling capacitors and detection impedance, and its low cut-off frequency of -3 dB was estimated to 3 kHz. B...
FIT-based colorectal cancer screening has been implemented in many countries including Denmark, where 916 colorectal cancer and 4468 high- or medium-risk adenoma patients were identified within April-December 2014, among 16,806 subjects with a positive FIT test. Screening increases the overall requirements for colonoscopy, which may challenge the current capacity. Some countries have increased ...
Background and Aims : One of the factors that lead to failure treatment and return substance abuse is ignoring mental disorders before and after drug withdrawal. Therefore, the aim of the present study was effectiveness of cognitive-behavioral group therapy on anxiety in addicts with successful cut off. Materials and Methods: This study was quasi-experimental. The study design was a pretes...
The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...
The performance of nanoscale Field Effect Diodes as a function of the spacer length between two gates is investigated. Our numerical results show that the Ion/Ioff ratio which is a significant parameter in digital application can be varied from 101 to 104 for S-FED as the spacer length between two gates increases whereas this ratio is approximately constant for M-FED. The high-frequency perform...
