OBJECTIVES This study aimed to evaluate the hypothesis that relief of nasal obstruction in subjects with obstructive sleep apnea (OSA) would lead to reduce OSA severity and to discuss the available evidence on the clinical efficacy of nasal surgery as a treatment modality for OSA. STUDY DESIGN Twenty-five subjects who had reduced patency of nasal cavity and narrowing of retroglossal or retrop...
2 The aim of this study was to establish threshold TGR and MDS values which could be 3 used in regulated deficit irrigation in future work. Three irrigation treatments were 4 performed during three seasons in a 37 year-old table olive orchard in Seville (Spain). 5 Control treatment was irrigated with 125% of the crop evapotranspiration. Regulated 6 deficit irrigation (RDI) treatments were perfo...
This study was designed to validate a new home portable respiratory recording device (PRRD) to identify sleep apnoea and hypopnoea in a group of subjects (n=116), from a sample of the general population. Full night polysomnography (PSG) was used as the gold standard and simultaneously performed with PRRD. PRRD measurements included oronasal airflow (thermistry), chest wall impedance, oxygen sat...
خشکسالی یکی از بلایای طبیعی است که در مقایسه با سایر بلایا از نظر شدت، طول مدت، گسترش منطقه، خسارتهای اقتصادی و اثرات بلند مدت آن از اهمیت چشمگیری برخوردار می باشد. هدف یک شاخص خشکسالی تعیین ساده و کمی ویژگی های اصلی از آن است که شامل شدت، تداوم، فراوانی و گستردگی مکانی می باشد. این تحقیق بر روی 41 ایستگاه سینوپتیک که در بخش های مختلف از ایران قرار گرفته اند و دارای آماری بیش از 30 سال می باشند...
comparability analyses are performed to investigate similarities/differences of the standard precipitation index (spi) and the reconnaissance drought index (rdi), respectively, utilizing precipitation and ratio of precipitation over potential evapotranspiration (et0). data are from six synoptic stations in south khorasan province in iran.at the first for calculating spi, the elevation-precipita...
INTRODUCTION Obstructive sleep apnea (OSA) is a well-recognized risk factor of cardiovascular disorders and is related to metabolic syndrome. The aim of this study was to evaluate the effect of BMI and AHI/RDI on metabolic disturbances in patients suspected of OSA. MATERIAL AND METHODS Ninety-nine patients referred with suspected OSA underwent standard polysomnography or limited sleep study. ...

Recently, Squire & Hopkins (2017) showed any coupled dust-gas mixture is subject to a class of linear “resonant drag instabilities” (RDI). These can drive large dust-to-gas ratio fluctuations even at arbitrarily small dust-to-gas mass ratios μ. Here, we explore the RDI in the simple case where the gas satisfies neutral hydrodynamics and supports acoustic waves (ω2 = cs k 2). The gas and dust ar...
In this preliminary study, the effect of regulated deficit irrigation (RDI) on commercial quality (size, weight, soluble solids, firmness and colour), content carotenoids, phenolics sugars black tomato (Solanum lycopersicum L.) ?Sunchocola? was studied. Two water treatments were applied: control with 82,7 398 mm supplied, respectively. Tomato first cluster harvested at three stages maturity The...
Abstract Funding Acknowledgements Type of funding sources: None. Introduction Obstructive sleep apnea (OSA) is associated with left atrial (LA) remodeling, which increases the thromboembolic risk fibrillation (AF) and recurrence after catheter ablation AF. This study aimed to assess association between severity OSA LA remodeling. Method In 126 patients AF who underwent for (male 78.4% male, 58....
