Automotive Systems A u to m o tive Sstem s Th e fuel pressure control system (FPCS) was developed to comply with increasingly strict fuel-effi ciency and emissions regulations by improving fuel economy and reducing emissions. It controls the discharge fl ow rate of the fuel pump and fuel injection pressure in accordance with engine operating conditions. Past fuel supply systems have operated th...

A unique normalized radial pressure profile characterizes the bed of a gas-solid vortex reactor over a range of particle densities and sizes, solid capacities, and gas flow rates: 950-1240 kg/m3, 1-2 mm, 2 kg to maximum solids capacity, and 0.4-0.8 Nm3/s (corresponding to gas injection velocities of 55-110 m/s), respectively. The combined momentum conservation equations of both gas and solid ph...

OBJECTIVE To determine if prophylactic use of intraocular pressure (IOP)-lowering medication is effective in reducing the IOP spikes after intravitreal injections of pegaptanib, bevacizumab, and ranibizumab. METHODS Seventy-one patients with exudative age-related macular degeneration received intravitreal injections of 1 of 3 anti-vascular endothelial growth factor medications: 30 patients re...

The state of melt viscosity in injection process is significantly influenced by the setting parameters due to that the shear rate of injection process is higher than other processes. How to determine plastic melt viscosity during injection process is important to understand the influence of setting parameters on the melt viscosity. An apparatus named as pressure sensor bushing (PSB) module that...

PURPOSE To investigate the effect of intramuscular Botulinum toxin type A (BoNT-A) injection on gait and dynamic foot pressure distribution in children with spastic cerebral palsy (CP) with dynamic equinovarus foot. MATERIALS AND METHODS Twenty-five legs of 25 children with CP were investigated in this study. BoNT-A was injected into the gastrocnemius (GCM) and tibialis posterior (TP) muscles...

AEiSTRACT Reinjection of spent geothermal brine is a common means of disposing of geothermal effluents and maintaining reservoir pressures. Contrary to the predictions of twefluid models (tweviscosity) of nonisothermal injection, an increase of injectivity, with continued injection, is often observed. Injectivity enhancement and thermally-affected pressure transients are particularly apparent i...

In coping with the trend toward the much higher powered electric-motor driven injection molding machine, multi-AC servomotors control system has become necessary in order to control the molding machine mechanism. Thus, it is inevitable to use a synchronous positioning control technique not to cause the excessive mechanical stress in the machine body. It is possible to realize the synchronous po...

In the most application of nozzle with gas-liquid two-phase flow, the quality of mixture in exhaust of nozzle is the most important parameter as well as the flow velocity. On the other hand, in some industrial application, such as water injection in forced induction (turbocharged or supercharged) internal combustion engine the spray quality is the main goal of designing. In this case and for im...

SUMMARY Responses to vertebral and aortic injection of synthetized angiotensin II of the systemic arterial pressure and heart rate were examined in humans and the following results were obtained: Angiotensin II injections in the dosages from 0.016 to 0.06ƒÊg./Kg. caused the following effects. 1) Vertebral injection produced a higher rise in the systemic arterial pressure than that produced by a...
