Measurement of stiffness of rock from laboratory and field tests Naeem O. Abdulhadi & Amjad F. Barghouthi Arab Center for Engineering Studies (ACES) ABSTRACT This paper compares the deformation modulus of rock measured from laboratory and field tests which were carried out as part of the site investigation works for a major project in Irbid‚ Jordan. Laboratory resonant column and torsional shear tests were performed at different confining pressures whereas ultrasonic velocity tests were

left planet earth and embarked on one of the most important missions in NASA’s history. I should probably back up though‚ and explain to you how this came about. April 16th was sunny with only a few clouds in the sky‚ the smell of spring was in the air and with the end of second semester right around the corner‚ the quad was packed with people eager to catch some much desired sun rays. Unfortunately for me though I was stuck in astronomy. That day’s topic was our very own planet earth. Dr. Bozyan

Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage to create a magnetic field that deflects the beam away from

Democritus and the atom: c.420 BC In the late 5th century BC Democritus sets out an interesting theory of elemental physics. Notions of a similar kind have been hinted at by other Greek thinkers‚ but never so fully elaborated. He states that all matter is composed of eternal‚ indivisible‚ indestructible and infinitely small substances which cling together in different combinations to form the objects perceptible to us. The Greek word for indivisible is atomos. This theory gives birth to the atom.
