AIMS To identify the frequency of cognitive and functional decline (CFD) among adults 50 years of age and older by a population-based study. METHODS Cognitive function was analyzed by the Mini-Mental State Examination, and the functional conditions were based on instrumental activities of daily living (IADL). Cases of CFD included individuals with cognitive decline and 2 or more compromised I...

This study describes the development, implementation, and evaluation of an effective curriculum for students to learn computational fluid dynamics (CFD) in introductory and intermediate undergraduate and introductory graduate level courses/ laboratories. The curriculum is designed for use at different universities with different courses/laboratories, learning objectives, applications, condition...

Curiosity as a feeling of deprivation (CFD) reflects feelings of uncertainty and tension that motivate information-seeking and problem-solving behavior. Twenty-seven CFD items were administered to 321 participants (248 women, 73 men) along with other measures of curiosity and other personality traits such as anxiety, anger, and depression. Factor analyses of the CFD items identified 3 factors f...

INTRODUCTION Altered total cavopulmonary connection (TCPC) hemodynamics can cause long-term complications. Patient-specific anatomy hinders generalized solutions. 4D Flow MRI allows in vivo assessment, but not predictions under varying conditions and surgical approaches. Computational fluid dynamics (CFD) improves understanding and explores varying physiological conditions. This study investiga...

For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computational fluid dynamics) software and desktop computing power have made it possible for some manufacturers to investigate unique fluid flow fields in routine design applications. In this paper, four case studies of CFD in high performance exp...

PURPOSE To report the findings of the clinical and molecular evaluation in a Greek family with fleck corneal dystrophy (CFD). METHODS A 58-year-old woman was seen on routine ophthalmic examination and diagnosed as having CFD. All available family members were examined to evaluate the clinical findings and inheritance of the disease. Twenty members of the family in five generations underwent s...

When coupling computational fluid dynamics (CFD) with a detailed thermal comfort model describing the human thermoregulation, the characteristics of the micro-climate of the human body have to be known. In the paper, CFD has been applied to investigate human body’’s micro climate. A climate chamber equipped with a thermal manikin has been used to validate the CFD simulations against measurement...

This paper introduces computational fluid dynamics (CFD), a numerical approach widely and successfully used in aerospace engineering, to deal with surface traffic flow related problems. After a brief introduction of the physical and mathematical foundations of CFD, this paper develops CFD implementation methodology for modeling traffic problems such as queue/platoon distribution, shockwave prop...

Although gender discrimination has been illegal in organizations since the passage of the Civil Right Act of 1964, individuals remain hesitant to claim internally by making members of their employing organization aware of gender discrimination. Yet surprisingly little research has examined the individual difference and contextual antecedents to internal discrimination claims. We advance an inte...

مدل سازی سینی برج تقطیر از این نظر که پارامترهای مختلف هندسی و شرایط عملیاتی را به راندمان مربوط می کند، از اهمیت زیادی برخوردار است. مدل سازی بر مبنای دینامیک سیالات محاسباتی، cfd، به این دلیل که بدون محدودیت هندسه و در بازه ی زمانی کوتاه تر، نتایج قابل قبولی را برای پیش بینی رفتار سیستم مهیا می کند، ابزار قدرتمندی است. از این رو مدل سازی هیدرودینامیکی و انتقال جرم سینی غربالی با روش cfd در سا...
