Articular cartilage is subjected to dynamic mechanical loading during normal daily activities. This complex mechanical loading, including cell deformation and interstitial fluid flow, affects chondroc...
Two-Dimensional Flow and NOx Emissions in Deflagrative Internal Combustion Wave Rotor Configurations
Two-Dimensional Flow NOx Emissions
2014/11/13
A wave rotor is proposed for use as a constant volume combustor. A novel design feature is investigated as a remedy for hot gas leakage, premature ignition, and pollutant emissions that are possible i...
Modified Through-Flow Wave-Rotor Cycle with Combustor-Bypass Ducts
Combustor-Bypass Ducts Through-Flow Wave-Rotor Cycle
2014/11/13
A wave-rotor cycle is described that avoids the inherent problem of combustor exhaust gas recirculation (EGR) found in four-port, through-flow (uniflow) pressure-gain wave-rotor cycles currently under...
Coil embolization of bronchial artery aneurysm with high flow bronchial artery-pulmonary artery fistula
Bronchial Artery Aneurysm Bronchial Artery-Pulmonary Artery Fistula Embolization
2013/2/19
We report a case of an asymptomatic 36-year-old man with a bronchial artery aneurysm in the right hilum. Selective angiography revealed a 25mmsaccular aneurysm and an efferent artery of the aneurysm f...
I like it but I don’t have time to tell patients’ families: Exploring barriers and facilitators of pain and dementia knowledge flow between healthcare providers and family caregivers
Dementia Pain Knowledge Translation Sticky Knowledge
2013/1/28
Pain in persons with dementia is prevalent, largely undetected, and undertreated within the care setting. Family members require resources to help them assume a more significant role in pain assessmen...
