BACKGROUND Little is known about factors affecting adherence to highly-structured and supervised exercise programs in older people. METHODS Healthy, inactive older (≥65 y) women (N = 30) were randomized into a 1) higher- (ATH-80% VO₂peak); 2) moderate- (ATM-65% VO₂peak) intensity aerobic; or 3) lower-intensity resistance (RTL; 50% VO₂peak) group. All 3 groups exercised 4 days·week⁻¹ for an av...
INTRODUCTION Obstructive sleep apnea syndrome (OSAS) is the most serious consequence of adenotonsillar hypertrophy (ATH). The gold standard diagnostic method is polysomnography (PSG) with nocturnal oximetry, but it requires expensive equipment, the presence of a technician and a specialized doctor, and is very time consuming, making the procedure difficult. The recording of pulse oximetry monit...
This paper reports the results of an across lab metanalysis of effective connectivity in major depression (MDD). Using FDG PET data and Structural Equation Modeling, a formal depression model was created to explicitly test current theories of limbic-cortical dysfunction in MDD and to characterize at the path level potential sources of baseline variability reported in this patient population. A ...
BACKGROUND Epidemiological studies indicate a statistical linkage between atherosclerotic vascular disease (ATH) and Alzheimer's disease (AD). Autopsy studies of cardiac disease in AD have been few and inconclusive. In this report, clinical and gross anatomic measures of cardiac disease were compared in deceased human subjects with and without AD. METHODS Clinically documented cardiovascular ...
گسترش روز افزون مطالعات انجام شده بر روی زئولیت ها، استفاده آن ها را در بسیاری از کشور ها مشخص ساخته است. در ایران نیز از نظر قیمت و دسترسی، تهیه این کانی ها بسیار آسان است. به همین دلیل استفاده از زئولیت ها در سال های اخیر رو به افزایش بوده است. در این مطالعه تاثیر استفاده از سه نوع زئولیت (کیلینوپتیلولیت، آنالسیم و هولاندایت) به عنوان پرکننده در دو سطح 15 و 30 درصد بر ویژگی های کاغذ حاصل از خ...
The use of fifth-generation (5G) new radio (NR) spectrum around 26 GHz is currently raising the quest on its compatibility with well-established Earth exploration-satellite service, which may be blinded by spurious radiation emitted above horizon (AtH) base station (BS) antennas. Indeed, AtH grating lobes are often present during cell scanning due to large interelement spacing in BS array anten...
The pyrolysis of solid polymeric materials is a complex process that involves both chemical and physical phenomena such as phase transitions, chemical reactions, heat transfer, and mass transport of gaseous components. For modeling purposes, it is important to characterize and to quantify the properties driving those phenomena, especially in the case of flame-retarded materials. In this study, ...
In recent years, wood fibres have often been applied as the reinforcement of thermoplastic materials, such as polypropylene, whereas their use in combination with thermosetting resin has been less widespread. This study concerns the production of PMMA-based composites by partly replacing alumina trihydrate (ATH) with wood waste fillers, namely rice husks and almond shells, which would otherwise...
