This paper describes a mathematical model for a novel rotary pneumatic rotary actuator with potential applications in revolute direct robotic mechanisms. The analytical model describes the behaviour of the rotary pneumatic actuator and simulated results using this model are generated. Potential applications of this model are discussed in the context of soft model based controllers used in prost...

Abstract Metal cutting fluids (MCFs) under flood conditions do not meet the urgent needs of reducing carbon emission. Biolubricant-based minimum quantity lubrication (MQL) is an effective alternative to lubrication. However, pneumatic atomization MQL has poor properties, which detrimental occupational health. Therefore, electrostatic requires preliminary exploratory studies. systematic reviews ...

Experiments in pneumatic chemistry paved the way for medical innovation in the last quarter of the eighteenth century. Thomas Beddoes and James Watt were instrumental in the spread of the use of new gas chemistry in pneumatic therapy, but they were far from alone. There was no shortage of experimental subjects, as the practice was quickly taken up by medics throughout Britain.

The electromagnet pneumatic proportional servo valve is widely used in industrial automation, medical equipment, scientific composition detectors, and other fields that require precise adjustment of high-pressure air flow due to its simple working structure, large output power, frequency response, good control performance. However, the pressure small, making it vulnerable impact external enviro...

The CoRoT project is a collaboration of French and UK partners funded by the EU Interreg Programme. research group has developed mobile robot demonstrating autonomous operations particularly aiming for applications within flexible manufacturing factories small to medium enterprises (SMEs). robot’s capability full separation classifies it as modular robotic system. Although possible, introduces ...

PURPOSE Intussusception is a common surgical emergency in infants and children. The incidence of intussusception is from one to four per 2,000 infants and children. If there is no peritonitis, perforation sign on abdominal radiographic studies, and nonresponsive shock, nonoperative reduction by pneumatic or hydrostatic enema can be performed. The purpose of this study was to compare the success...

Computational Fluid Dynamics (CFD) simulations of gas-solid flow through a positive low-pressure pneumatic conveyor were performed using Eulerian-Eulerian framework. Pressure drop in pneumatic conveying pipelines, creation and destruction of plugs along the horizontal and vertical pipes, effect of 90° elbows and U-bends on cross-section concentrations, and rope formation and dispersion were...

BACKGROUND Pneumatic tourniquets are medical devices that occlude blood flow to distal part of extremities and are commonly used in upper limb surgeries to provide a dry, clean and bloodless field. To decrease pressure-related injuries and potential risk of complications subjected to the high inflation pressure of pneumatic tourniquet, minimal inflation pressures are recommended. METHODS A ne...

BACKGROUND Pneumatic compression of the lower part of the body increases systemic vascular resistance and left ventricular afterload. AIM We compared the diagnostic accuracy of dobutamine stress echocardiography (DSE) with pneumatic compression of the lower extremities, vs. standard DSE, for detection of angiographically significant coronary artery disease (CAD) in patients with normal baseli...
