OBJECTIVE Clinicians commonly recommend that power wheelchair users with spinal cord injury perform wheelchair tilt and recline maneuvers to redistribute seating loads away from the ischial tuberosities. However, ischial pressure reduction may be accompanied by coccygeal pressure increases. Although the coccyx is among the most common sites of pressure ulcers, few studies have reported coccygea...

This paper highlights the influence of contact line (pinning) forces on the mobility of dry bubbles in microchannels. Bubbles moving at velocities less than the dewetting velocity of liquid on the surface are essentially dry, meaning that there is no thin liquid film around the bubbles. For these "dry" bubbles, contact line forces and a possible capillary pressure gradient induced by pinning ac...

Back Cover: In article number 2100251, Qiang Zhang and co-workers propose a flexible pressure sensor based on graphene/[email protected] The exhibits high sensitivity (0.053 kPa?1), stability (2000 cycles loading) variability (0 – 35 kPa detection limit). Furthermore, the array can effectively detect static pressure, systolic corresponding abnormal in rectal model experiment, which show good pr...

This paper deals with a multi-objective optimization of a novel micro solar driven combined power and ejector refrigeration system (CPER). The system combines an organic Rankine cycle (ORC) with an ejector refrigeration cycle to generate electricity and cold capacity simultaneously. Major thermodynamic parameters, namely turbine inlet temperature, turbine inlet pressure, turbine back pressure, ...

OBJECTIVES Propofol causes considerable pain upon injection, although different methods and propofol formulations have been used to decrease this pain. We aimed to investigate the effect of i.v. esmolol pretreatment on propofol injection pain. METHODS Ninety ASA I-II patients undergoing elective surgery under general anesthesia were randomly assigned into three groups of thirty each. A 20 G c...

The systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) daily profiles incidence was studied in 53 patients with arterial hypertension. A significant difference in the frequency of occurrence of different types of SBP, DBP and PP daily profile was revealed. In the structure of SBP daily profile nondipper and dipper types were dominated, DBP dipper and overdippe...
