Rev Esp Cardiol. 2009;62(11):1332-44 1341 a better understanding of the kinetics of said markers could lead to improvements in their use in cardiovascular diseases. Considering the diversity of the diurnal variations in the intrinsic properties of the cardiovascular system, these should be kept in mind during the design of in vivo experimental studies. Such temporal decisions will undoubtedly r...
Deposition of heteroepitaxial diamond via microwave chemical vapor deposition has been performed on a 4H-SiC substrate using bias enhanced nucleation followed by a growth step. In future work, the diamond film will serve as a protective layer for an alpha particle sensor designed to function in an electrorefiner during pyroprocessing of spent fuel. The diamond deposition on the 4H-SiC substrate...
Recent development in the Internet and Web based technologies require faster communication of multimedia data in a secure form. A number of encryption schemes for MPEG have been proposed. In this paper, we evaluate the compression performance of JPEG which has been encrypted with the zig-zag permutation algorithm, suggest a security enhancement to the scheme, and propose an alternative to entro...
Diamond thin films grown on high resistivity, (100) oriented silicon substrates by the hot filament chemical vapor deposition (HFCVD) method have been characterized by four-point probe and current-voltage (through film) techniques. The resistivities of the as-grown, chemically etched and annealed samples lie in the range of 1 O* fl cm to 10’ 0 cm. The Raman measurements on these samples indicat...

Introduction: Pressure ulcers occur in areas with bony protrusions exposed to pressure. Its incidence is between 1.6% and 49%. Due respiratory failure Covid-19, patients are frequently followed up intensive care units. Some of the intubated, support provided a ventilator. The risk developing pressure sores increases for long time on This study was conducted investigate frequency Covid-19 patien...
In this study, it was aimed to determine the agronomic and chemical components of Origanum dubium, which grows naturally in Ermenek region. The plants used experiment were collected at 5 different altitudes (467, 1096, 1331, 1332 1478 m) district Karaman. carried out garden Vocational School for 3 years 2014, 2015 2016, field Field Crops Department Çukurova Univ. 2 2016. For O. dubium cultivate...
The aim of this study is to investigate the gamma ray radiation absorption properties bismuth oxide (Bi2O3), and determine effect lead (PbO) additive in shielding Bi2O3. For reason, parameters such as mass attenuation coefficient (MAC), linear (LAC), half value layer (HVL), tenth (TVL) mean free path (mfp) were calculated theoretically for Bi2O3, PbO, 50% Bi2O3-50%PbO. all results obtained by u...
Lockdowns put in place response to the COVID-19 health crisis have changed daily functioning for families and potentially emotional experience of individuals their parenting role. Our study aimed highlight importance environmental consequences associated with lockdowns on parental burnout. We compared data burnout levels from two French samples: first collected 2018 ( N = 1332) second during la...
هنوز یک دهه از تاسیس دانشگاه تهران نگذشته بود که ایران در فضای جنگ جهانی دوم و اشغال متفقین ، استقلال خود را در خطر دید. با برکناری رضاشاه از قدرت و روی کار آمدن محمد رضا شاه که موجب بازتر شدن فضای سیاسی گردید فعالیت ها و تحرکات نسبتاً وسیعی در سطح جامعه و به تبع آن در بین دانشجویان و دانشگاه پدید آمد شاید بتوان مطالباتی همچون استقلال، آزادی و احیای مشروطیت را مهمترین خواسته های مردم و دانشجویان...
