Normal human peak systolic blood flow velocities vary with age, cardiac output, and anatomic site. At the aortic valve, peak velocities of up to 500 cm/sec may be possible. The ascending aorta has the highest average peak velocities of the major vessels; typical values are 150-175 cm/sec....
Curve numberClimate changeSoil moistureBias correctionPeak flowClimate projections point to modifications in the magnitude, frequency and timing of floods in the future. However, robust methodologies to quantify how climate change will modify the catchment response in flood events are required. Continuous...
These methods are most familiar when the reference population is census based, for example, the overall survival experience of the United States population by age and sex. Recently, these ideas have been rediscovered and applied to the proportional hazards model. In this case the reference ...

(Si70Ge30P3)0.35.The Si nanoparticles form proper band alignments with the SiGe matrix to promote the flow of carriers from the nanoparticles into the matrix.The enhancement in electrical conductivity comes from the 50% improvement of the carrier mobility.Additionally,the thermal conductivity can be...
Fact check: Renewable energy is not to blame for the Texas energy crisis Natural gas, the state’s dominant energy source, has provided drastically less energy than expected, according to experts and industry data. […] “Wind was operating almost as well as expected,” said Sam Ne...
citizens very unhappy because wages do not rise to compensate for this inflation. Prices today are high enough to cause significant inflation (about $107 per barrel for Brent oil (Europe) and $97 for WTI (US)), but still not high enough to satisfy th...
The first hint I had of the approach of Winter Storm Younger Dryas was on Monday, February 8. Not being hurricane season, I wasn’t paying too close attention to the weather. The forecast on Monday was for possible freezing rain overnight on Wednesday… But the scary bit was a forecast ...
