در این تحقیق، از شاخصهای SPIRDI و SPEI برای تحلیل روند شدت- مدت- فراوانی خشکسالی در مناطق خشک و نیمهخشک ایران استفاده گردید. تعداد 25 ایستگاه سینوپتیک در اقلیم فوق با طول دوره مشترک آماری (1996-2014) انتخاب و شدت، مدت و فراوانی خشکسالی در هشت زیراقلیم برآورد گردید. نتایج نشان داد که روند خشکسالی ا...
Although chronic sleep fragmentation and oxygen saturation (Sao2) drops alone do not induce obstructive sleep apnoea (OSA), both are part of the feedback loop leading to obstructive sleep apnoea syndrome (OSAS). To determine factors in respiratory disturbance and Sao2 drops, we used polysomnographic and cephalometric data from 120 OSAS patients to construct a model which we then applied prospec...
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...
هدف از این تحقیق تعیین سه شاخص SPI، RDI و SDI در پایش خشکسالیهای هواشناسی و هیدرولوژیکی در دشت بم و بررسی ارتباط آنها با یکدیگر، تحلیل مشخصههای خشکسالی در مقیاسهای زمانی مختلف و احتمال وقوع آنهاست. بررسی نتایج حاصل با استفاده از آزمون t جفت شده نشاندهنده تفاوت معنیدار در نتایج شدت، مدت و فراوانی در شاخص SPIباRDI بوده و بیشترین شباهت ویژگیهای یاد شده SDI با RDI بهدست آمد. نتایج آزم...
OBJECTIVE To evaluate the subjective and objective outcomes of extended uvulopalatal flap (EUPF) surgery in patients with obstructive sleep apnea. DESIGN Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), Snore Outcomes Survey (SOS), Epworth Sleepiness Scale (ESS), and polysomnography were performed preoperatively and then 6 months postoperatively. SETTING Tertiary care, sleep...
In light of climate change and its impacts on plant physiology, optimizing water usage and improving irrigation practices play a crucial role in crop management. In recent years, new optical remote sensing techniques have become widespread since they allow a non-invasive evaluation of plant water stress dynamics in a timely manner. Unmanned aerial vehicles (UAV) currently represent one of the m...

OBJECTIVES/HYPOTHESIS Determine the feasibility and accuracy of using virtual surgical planning (VSP) to direct the surgical and polysomnography (PSG) outcomes of patients with obstructive sleep apnea (OSA). STUDY DESIGN Prospective case series. METHODS Skeletal and soft tissue dimensions were measured from computed tomography (CT) to include posterior airway space (PAS) diameters at the oc...
Anterior mandibular positioners (AMPs) have become increasingly popular as alternatives to continuous positive airway pressure for the treatment of obstructive sleep apnea. However, widespread acceptance of AMP is limited by an efficacy rate of 50-80% and an inability to predict which patients will respond to therapy. We evaluated 23 patients with obstructive sleep apnea (respiratory disturbanc...
