BODY POSITION AND MECHANICS OF BREATHING. INFLUENCES OF CHANGING BODY POSITION UPON PULMONARY COMPLIANCE AND MECHANICAL RESISTANCE

Breathing Position Influences Speech Perception

Participants were asked to breath through their mouth or their nose, forcing them to adopt a particular position of their velum (up or down). While breathing in each of these positions, they categorized sounds from an /ada/ to /ana/ continuum. The position of the speech articulators, even though adopted for the purposes of breathing, altered participants’ perception of external speech sounds, s...

The Effect of Body Position Change on Lung Compliance

Since the work of Christie and Meakins (1), the lungs of patients with heart failure have been acknowledged to resist inflation to a greater extent than normal lungs. More recent studies of pulmonary mechanics in patients with congestive heart failure (2-5) have emphasized the lowered lung compliance as well as moderate increases in pulmonary resistance. That acute changes in lung compliance ca...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Position-based rigid-body dynamics

We propose a position-based approach for largescale simulations of rigid bodies at interactive frame-rates. Our method solves positional constraints between rigid bodies and therefore integrates nicely with other position-based methods. Interaction of particles and rigid bodies through common constraints enables two-way coupling with deformables. The method exhibits exceptional performance and ...
