Reducing the friction of liquid flows on solid surfaces has become an important issue with the development of microfluidics systems, and more generally for the manipulation of fluids at small scales. To achieve high slippage of liquids at walls, the use of gas as a lubricant--such as microbubbles trapped in superhydrophobic surfaces--has been suggested. The effect of microbubbles on the effecti...

Abstract Introduction Previous research has shown that comfort, including comfort of the sleep surface, is essential to quality. In addition structure and firmness a mattress may also play role when it comes More empirical needed establish impact particular mattresses on both objective self-reported measures This study compared an innerspring participants’ prior their original mattress. Methods...

BACKGROUND Retears after rotator cuff repairs occur relatively frequently and may compromise the functional result. The goal of this study was to analyze the mechanical properties following arthroscopic techniques for rotator cuff repair and to evaluate possible alternative techniques. METHODS In the first part, five different bone anchors (the Revo screw; Mitek Rotator Cuff anchor, 5.0-mm St...

STUDY DESIGN A biomechanical cadaveric study. OBJECTIVE We sought to determine the amount of motion generated in an unstable cervical spine fracture with use of the vacuum mattress versus the spine board alone. Our hypothesis is that the vacuum mattress will better immobilize an unstable cervical fracture. SUMMARY OF BACKGROUND DATA Trauma patients in the United States are immobilized on a ...

Background The National Athletic Trainers' Association (NATA) advocates for cervical spine immobilization on a rigid board or vacuum splint and for removal of athletic equipment before transfer to an emergency medical facility. Purpose To (1) compare triplanar cervical spine motion using motion capture between a traditional rigid spine board and a full-body vacuum splint in equipped and unequ...

Recognition of sleep patterns and posture has sparked interest in various clinical applications. Sleep postures can be monitored autonomously constantly to provide useful information for decreasing health risks. Existing systems mostly use images train the model learn based on many sensors. For example, a camera, pressure sensor, electrocardiogram. In this study, (named as SleepCon) was designe...

EARLYBUDDY is a smart alarm clock app for Android devices. It primarily uses traffic data to help the user wake up on time when there an estimated delay. Users can choose timeframe within which they must awaken rather than single wake-up time. The will then select inside that window based projected delay frequent updates. If it detects be late their destination, change existing them up. also sp...
