In order to improve the diesel engine performance under plateau (high altitude) conditions, a new Speed Adjustable Compound (SAC) supercharging method is proposed. A simulation model based on a six-cylinder V-type turbocharged intercooler diesel engine is built on the GT-POWER platform, and then simulation-based research is carried out. A genetic algorithm (GA) is used to identify the best oper...

BACKGROUND Risk factors and techniques for free flap salvage in head and neck reconstruction are poorly described. METHODS We conducted a retrospective review of all head and neck free flaps performed from 2000 to 2010. RESULTS Overall, 151 of 2296 flaps (6.6%) underwent salvage for microvascular complications. Age, comorbidities, surgeon experience (p = .88), vein grafts, and supercharging...

Maintenance of high-level transgene expression is the main challenge in current gene therapy. Although the cytomegalovirus (CMV) promoter/enhancer or its derivative the CAG promoter has been harnessed in current gene therapy vectors, transgene expression by these vectors is often transient and remains at suboptimal levels due to undefined mechanisms, possibly including the shortage of transcrip...

Variations of the distally based sural artery flap have been used in the literature with varying success rates. This article stresses the axiality of this flap based on the sural nerve and the short saphenous vein. Forty distally based sural artery flaps were used for a variety of defects in the distal leg. In the proximal leg, the groove between the medial and lateral heads of the gastrocnemiu...

Pulse hydraulic fracturing (PHF) is a key technique for reservoir stimulation. PHF can well accelerate the rupture of rock. However, supercharging mechanism not fully understood. The main reason that pressure distribution and its variation, especially peak characteristics, are unclear inside pipe fissure. present research focuses on sine pulse applied at inlet or fracture to reveal variation re...

Recently, many vehicle manufacturers started to invest in new technology reduce the emission produced by their engines. Due regulations that become more stringent and rising demand for highly efficient vehicles, technologies were introduced achieve demand. One of gain popularity modern vehicles is applying force induction systems such as turbocharging supercharging engine. By using turbocharger...

Well-defined containers constructed from multiple protein subunits are a unique class of nanomaterial useful in supramolecular chemistry and biology. These cages widespread nature, where they responsible for diversity important tasks. As such, producing our own designer cages, complete with bespoke functionalities, is promising avenue to new nanodevices, biotechnology therapies. Herein, we desc...
