Metamaterials can exhibit electromagnetic and elastic characteristics beyond those found in nature. In this work, we present a design of elastic metamaterial that exhibits multiple resonances in ...

SATURDAY AND SUNDAY: Both days are uncomfortably hot. Max heat index = 100 to 105. Light wind Saturday, then you’ll feel a ...

Any natural earthquake shows a distinct pattern of seismic waves, recorded with a seismogram. A seismometer will first detect the Primary (P- or compressional waves) and Secondary (S- or ...

For the compressional wave (P-wave), the appropriate value of E is K + 4/3 μ or λ + 2μ, while for the shear wave (S-wave) the appropriate value of E is μ. 1-4 The λ is Lame's constant.

Compressional heating is the result of downsloping wind coming off the mountains. That air is compressed, which will lead to an increase in temperature and a drop in relative humidity.

Seismological observations of the 2012 moment magnitude 8.6 Sumatra earthquake reveal unprecedented complexity of dynamic rupture. The surprisingly large magnitude results from the combination of deep ...

This comparative study suggests that pregelatinized starches are superior to natural starches in terms of improving the plastic deformation in tablet formulations during compression.

Compressional and transpressional structures provide some of the world's largest known hydrocarbon reservoirs and remain major frontier plays. 3-D seismic has revolutionized structural ...

Weather Talk: Compressional heating The hot weather of the past few days has been caused in part by a process in the atmosphere known as compressional heating. When the high pressure forms in the ...

I’ve heard you refer to compressional heating. What is it? Paolo McPaki Evanston Dear Paolo, When air descends in the atmosphere it is compressed, undergoing an increase in temperature and density.
