The mean effective pressure, power output, and thermal efficiency are obtained by introducing the compression ratio, cycle temperature ratio, specific heat ratio and the compression and expansion efficiencies. Optimal performance and design parameters of the Otto cycle are obtained analytically for the ...
Similarly, thecontractile stateof the myocardium can be obtained from the maximum velocity ofblood flowin theascending aortaduring the cardiac cycle (i.e., the initial slope of theaortic flowcurve; seeFigure 4-13). Also, theejection fraction, the ratio of the volume of blood ejected from the...

Low-pressure die cast (LPDC) is widely used in high performance, precision aluminum alloy automobile wheel castings, where defects such as porosity voids a
We observed that only within the surface layer, cells represented a ‘round’ shape and were loosely organized, while within the structure cells appeared progressively compressed towards the core, in the radial direction, and stretched in the ortho-radial plane, with an aspect ratio larger than ...

We found that each genetically associated, 20-mm Hg higher systolic BP was associated with approximately 3-fold higher odds of aortic stenosis in an age- and sex-adjusted model (odds ratio [OR], 3.29; 95% CI, 1.52-7.12; P = .002). Adjustment for additional variables minimally ...

In an Otto or Diesel engine, 29% of the energy in the fuel is transferred to the cooling system, and 33% goes to the exhaust system. With hot cylinder walls, the cooling can virtually disappear. With a higher expansion ratio than compression ratio, the exhaust losses can diminish. Losses...
