Development of a Descriptive Model of Flow Disruption Effect on Bypass Time in a Cardiovascular Operating Room
<p>The current paper proposes utilizing extant flow disruption data, collected from two cardiovascular operating rooms, and utilizing that to develop a mathematical model. Of particular interest is bypass time which is a critical surgical phase, the length of which has been linked to post-operation …

Development of a superabsorber based haemofiltration technology for use in paediatric cardiac surgery
… bovine blood, computational modelling of blood flow and scanningelectron microscope imaging of the control membrane highlighted the importance of bothutilising flow disruption techniques to limit fouling, and controlling the swelling behaviour ofthe superabsorber material, in achieving rapid …

Optimizing interventions for the treatment of vascular flow disruptions
… rely on perfusion and therefore intact blood flow. When flow is disrupted the coupled interaction between the functional and fluid domains of a tissue is impeded and viability is lost. Aortic stenosis is a paradigmatic example of vascular flow disruption. In health there is no gradient across …

Numerical Wing/Store Interaction Analysis of a Parametric F16 Wing
… the effects of the pylon induced lateral flow disruption as well as wing-tip-vortex effects. It can identify the presence of aerodynamic interference between the store, pylon, and wing wakes and examine its significance with respect to the pressure and lift forces on the participating …

High Speed Acoustophoresis for Multiphase Micron-Sized Particle Assembly
… power also increases streaming, a bulk fluid flow which destroys the assembled pattern when large enough and, thus, caps transducer power, setting a floor on particle size and assembly time. This thesis presents a strategy for circumventing the streaming flow disruption- assembling particles …

Turbulent interactions with normal shocks and their effects on aluminum particle burn time
… indicative due to poor seeding capabilities and flow disruption when the seeded particles were swept o the loading plate in the shock tube. An estimated 1% turbulence intensity was still observed in the laminar case, although it is clear from the velocity profi les that the fl ow is significantly …

Zonal flows in accretion discs and their role in gravito-turbulence
This thesis focuses on the evolution of zonal flows in self-gravitating accretion discs and their resulting effect on disc stability; it also studies the process of disc gravito-turbulence, with particular emphasis given to the way the turbulent state is able to extract energy from the background …

Development of a continuous flow microreactor for chemical synthesis with in-line catalysis, heating and detection
The development of a micro fluidic flow organic synthetic system incorporating heterogeneous catalysis, novel heating regimes and in-line spectroscopic detection is described. The reactions used to model the flow synthesis include Suzuki and acetylation reactions using heterogeneous immobilised …

The Identification and Classification of Flow Disruptions in the Operating Room during Laparoscopic Cholecystectomy and Open Hernia Repair Procedures
… to medical error occur in the operating room. Flow disruptions are events that cause a "break" in the primary surgical task, or the loss of any team member's situational awareness. An empirical link between flow disruptions and surgical errors in the OR has been established; therefore, …
