Critical Radius Curve Crash Density Nationally, lane-departure crashes frequently occur within curves. Curves with radii between 500 and 1,200 feet (that is, critical radius curves) have a higher serious crash rate than other curves and roadway segments with more curves in this range are considered to

Get PriceThe liquefaction step is skipped. Near the Critical Temperature occurs homogeneous nucleation. Once the bubbles have reached a critical radius, they explode in a mixture of steam and droplets. Using a Marx electric machine, 500 J of electrical energy are brutally discharged in a metallic hollow ellipsoid submerged in water, as shown in Fig 2.

Get PriceMany proteins contain regions of unstructured polypeptide chain that appear to be flexible and to undergo random thermal motion. In some cases the unfolded sequence acts as a flexible tether that restricts the diffusion of a globular protein domain for the purpose of catalysis or self-assembly. In this article, we present a stochastic model for tethered protein domains under various conditions

Get PriceKurt Hensel (1861-1941) discovered the p-adic numbers around the turn of the century. These exotic numbers (or so they appeared at first) are now well-established in the mathematical world and used more and more by physicists as well. This book offers a self-contained presentation of basic p-adic analysis. The author is especially interested in the analytical topics in this field.
