PWV measurement influenced by distance between two recording sites.
To the Editor: We have read the recent letter by Hermeling et al. entitled “Potentials and Pitfalls of Local PWV Measurements,”1 discussing the advantages and challenges for local pulse wave velocity (PWV) measurements. The letter was in reference to an article by Vappou et al. regarding pulse wave imaging measurement of arterial stiffness in vivo.2 In the common carotid artery, due to the susc...
متن کاملبررسی امکان پیش بینی بارش با برآورد بخارآب تعلیق پذیر از مشاهدات GNSS به روش تعیین موقعیت مطلق دقیق
در علوم نقشهبرداری از سامانه‌ی ناوبری ماهواره‌‌ای جهانی (GNSS) برای اهداف ژئودتیک و ژئودینامیک استفاده شده است ولی در سال‌های اخیر از این سامانه برای اندازه‌گیری پارامترهای جو کره‌ی زمین نیز استفاده شده است. یکی از این پارامترها، بخار آب تعلیق‌پذیر (PWV) اتمسفر می‌باشد. امکان اندازه‌گیری PWV توسط گیرنده‌های GNSS، به واسطه‌ی تأخیر اتمسفری ایجاد شده در سیگنال ارسال شده از طرف ماهواره فراهم می‌شو...

TOWNSEND LETTER – MAY 2010 This article explores an exciting, noninvasive, easy-to-use, and economical method of assessing patients’ cardiovascular physiologic status that is backed by more than 25 years of advanced research in medical physics. A 2007 Clinical Medicine article points the way to better clinical treatment of CVD, stating: “Arterial stiffness measured by pulse wave velocity (PWV) ...
متن کاملDecadal variations in atmospheric water vapor time series estimated using ground-based GNSS
Ground-based GNSS (Global Navigation Satellite Systems) have efficiently been used since the 1990s as a meteorological observing system. Recently scientists used GNSS time series of precipitable water vapor (PWV) for climate research. In this work, we use time series from GNSS, European Center for Medium-Range Weather Forecasts Reanalysis (ERA-Interim) data, and meteorological measurements to e...
متن کاملThe quality of nursing documentation in some private and provincial hospitals in the Cape Peninsula and the PWV--area.
An investigation was undertaken with the aim of establishing standards for the documentation of nursing care. Nursing care records in the medical and surgical units of private and general hospitals in the PWV-area and the Cape Peninsula were audited. A considerable number of deficiencies were identified in the daily record keeping of nursing care.
