A storage battery is a cell. or a series of cells capable of storing up electric energy and giving it off at a required time. A storage battery acts upon the same principle as a galvanic cell in giving forth electric current as the equivalent of chemical energy, but it...
Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...
The problems facing our nation's public schools today cannot
be divorced from our enthusiasm for technology and the positive
relationship we believe it shares with our perception of progress.
Based on the second law of thermodynamics, the law of entropy,
author Jeremy Rifkin argues that the development of increasingly
"efficient"...
The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...
Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...
During the depression era, millions of Americans listened to the weekly radio
addresses given by Father Charles Edward Coughlin. He devoted his career to
speaking out against the evils of America and felt it his duty to warn Americans
against the perpetrators of this evil. But after 1934, the tone...
For several years researchers have investigated how teachers’ beliefs
impact a classroom. Equally important to consider when striving to improve
education are the beliefs held by the students. College Algebra is an important
class for many collegiate students, and gaining an insight into their beliefs about
mathematics and desires for...
