in this research, the effect of different storage conditions (cold, semi technical and traditional storages) at 180 days after storage on the qualitative and quantitive properties of garlic populations were investigated. white and pink populations were packaged in wooden boxes and net pockets and factors i. e. weight loss, moisture content, spoilage, firmness and total pyruvic acid were measure...
conclusions significant difference in the fundamental frequency, jitter, shimmer, silence duration, friction duration, vocalization duration, and vocal cords contact quality index between the two groups was observed (p < 0.01). results the mean of fundamental frequency for the hearing loss children and the control group were 323.04 hz and 267.53 hz, jitter 10.05% and 1.52%, shimmer 17.24 and 5....
background: military personnel are usually exposed to high levels of impulse noise (in) which can lead to hearing loss. objectives: the purpose of this study was to assess the effects of relatively low level exposure of impulse noise (in) during shooting practice on hearing using pure tone audiometry (pta) and transiently evoked otoacoustic emission (teoae) in military personnel. materials and ...
امروزه تولید الکتریسیته با نشر آلودگی کم و بازده بالا، یکی از مهم ترین اهداف محققین می باشد. در پایان نامه حاضر سیستم ترکیبی تولید همزمان سرمایش، حرارت، قدرت (cchp) با تکنولوژی سرمایش تبرید جذبی، راه اندازی شده توسط انرژی خورشیدی معرفی گردیده. سیال عامل سیکل معرفی شده برای هر سه زیرسیستم تولید توان، حرارت، سرمایش مخلوط دو جزئی آب – آمونیاک می باشد. به منظور محاسبه خواص مخلوط آب – آمونیاک در شرا...
Aims. As a part of the CALYPSO Large Program, we aim to constrain properties protostellar jets and outflows by searching for corresponding emission in sample 21 Class 0 protostars covering broad range internal luminosities ( L int from 0.035 ? 47 ). Methods. We analyzed high angular (~0.??5–1.??0) resolution IRAM Plateau de Bure Interferometer (PdBI) observations three typical outflow jet trace...
abstract the aim of this study, is to evaluate the effect of loss methods application on run-off volume and hydrograph shape used by hydrologic models. in this research, four loss methods including constant loss (φ index), initial loss-loss rate, scs and constant fraction approach were applied to be evaluated. to do this, clark rainfall-runoff model was applied for 24 storm events from kasilain...
portfolio theory assumes that investors accept risk. this means thatin the equal rate of return on the two assets, the assets were chosenthat have a lower risk level. modern portfolio theory is accepted byinvestors who believe that they are not cope with the market. sothey keep many different types of securities in order to access theoptimum efficiency rate that is close to the rate of return o...
background and aim: this article carries out a literature review of the quality and limitations of the narrative-based language intervention (nbli) for preschool and school-age hearing aided and cochlear implanted children. recent findings: the authors conducted a comprehensive search of electronic databases such as web of science, scopus, pubmed, google scholar, cochrane, and proquest from 198...
