Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of Foot Pedal acute myocardial infarction.We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention.Although preop
Underwater glider (UG) is one of the most promising autonomous observation platforms for long-term ocean observation, which can glide through seawater columns by adjusting its buoyancy and attitude.Hydrodynamic shape, especially the wing parameters, has an important influence on the glide performance of UG.In this paper, a sweep wing strategy inspi
An exhaust vent with a baffle and its corresponding evaluation index are proposed in this paper to increase the heat and contaminant extraction efficiencies for stratified smoke flow in tunnel fires.Numerical simulation and small-scale experiments are performed to investigate the effects of baffles beneath the exhaust vent on the flow pattern and t
Aim To explore the characteristics of online STI test users, and assess the frequency and factors associated with subsequent service use following a negative online STI test screen in individuals without symptoms.Methods One-year retrospective study of online and clinic STI testing within a large integrated sexual health service (Umbrella in Birmin
Saudi Arabia intends to reduce GHG emissions by 278 million tons of CO2eq annually by Foot Pedal 2030 through Nationally Determined Contribution (NDC) to UNFCCC.Among many policies, mass transit system and transit-oriented development are being developed with the expectation to reduce energy consumption and GHG emissions in Riyadh.To what extent su
