Pressure necrosis of the skin is a rarely reported avoidable complication of prone positioning that can be minimised by active collaboration between care teams. We report a case of pressure necrosis of the chin after prone ventilation in the intensive care setting. Such injuries pose a risk of infection, possible need for surgical intervention, and increased costs to the health care system. Pre...

Model parameters of conditioned soils in head chamber of shield machine are determined based on tri-axial compression tests in laboratory. The loads acting on tunneling face are estimated according to static earth pressure principle. Based on Duncan-Chang nonlinear elastic constitutive model, the earth pressures on head chamber of shield machine are simulated. The variation of earth pressure on...

The brittle fracture of a gypsum cylinder, which is used as an artificial kidney stone in lithotripsy research, is simulated by the use of the finite element method. The cylinder is submerged in water and is subjected to a pressure front parallel to one of its planar faces. The stresses induced by the pressure wave lead to fracture in the interior of the cylinder, with the formation of a spall ...

BACKGROUND Stroke is the leading cause of adult disability in the UK. Hypertension is the leading modifiable risk factor for stroke. There is increasing interest n home blood pressure monitors for self-monitoring, but no published research on the experiences of stroke patients who do self-monitor. AIM To explore stroke patients' experiences of self-monitoring with nurse-led support. DESIGN ...

BACKGROUND The rate of blood pressure control among hypertensive patients is poor and the reasons for poor control of blood pressure remain poorly understood globally. OBJECTIVE To assess the rate of blood pressure control among adult hypertensive patients at Jimma University Specialized Hospital. MATERIALS AND METHODS We conducted a hospital based cross sectional study among adult hyperten...

Pressure ulcers, localized areas of tissue damage or necrosis that develop due to pressure over a bony prominence, are common causes of morbidity in older hospitalized and institutionalized persons. Other terms referring to the same phenomena are pressure sores, bedsores, and decubitus ulcers. Risk factors include immobility, friction, shear, incontinence, cognitive impairment and poor nutritio...

Introduction: Brain injury induced coma is the main cause of hospitalization of patients in the intensive care unit (ICU) and their consequent stressful physiological complications, which can be prevented using sensory stimulation as a therapeutic method. Nevertheless, identifying and using the optimal sensory stimulation program is crucial. Objective: The present study was conducted to de...

The monolithic catalytic converter is still the main pollution control device for modern vehicles in order to reach the ever-increasing legislative demands for low emission standards. The catalytic converters require a large expansion from the exhaust pipe to the front face of the monolith. Unfortunately, packaging constraints often do not permit the use of long diffusers. Hence, flow separa...

This study presents effects of the vane spring stiffness on frictional power characteristics of a refrigeration compressor. Comparisons on the compressor performance are investigated for different vane spring stiffnesses with compressors designed with high and low shell pressures. Results show that while compressors with a low shell pressure using a higher spring stiffness combination may reduc...
