The Pierson–Moskowitz (PM) spectra is an empirical relationship that defines the distribution of energy with frequency within the ocean.. Developed in 1964 the PM spectrum is one of the simplest descriptions for the energy distribution.
The pier of a bridge is an intermediate support that holds the deck of the structure. It is a massive and permanent support, as opposed to the shoring , which is lighter and provides temporary support.
The downward pressure gradient at the pier face directs the flow downwards. Local pier scour begins when the downflow velocity near the stagnation point is strong enough to overcome the resistance to motion of the bed particles. During flooding, although the foundations of a bridge might not suffer damage, the fill behind abutments may scour.

Former Republican National Committee Chair Ronna McDaniel said Sunday that she disagrees with former President Donald Trump’s plan to free those charged and convicted of crimes in the Jan.
All magnitude scales retain the logarithmic scale as devised by Charles Richter, and are adjusted so the mid-range approximately correlates with the original "Richter" scale. [8] Most magnitude scales are based on measurements of only part of an earthquake's seismic wave-train, and therefore are incomplete.
The Miami Bridge, also known as the McDaniel Memorial Bridge, is a new concrete girder bridge that was built to replace a cantilever through truss bridge over the Missouri River at Miami, Missouri between Saline County, Missouri and Carroll County, Missouri. The Miami Bridge carries Route 41. The Miami Bridge was built in 1939, and its deck was ...
The central plot device is the "macroscope", a large crystal that can be used to focus a newly discovered type of particle, the "macron". Macrons are not subject to many of the effects that interfere with light, and as a result the macroscope can focus on any location in space-time with exceptional clarity, producing what is essentially a telescope of infinite resolution in the space-time ...
