Modern Technology vs. the Simpler Times What was life like back in the simpler times? Everyone can agree that life back then was extremely different from what it is today. There were no phones‚ or e-mail. No Facebook‚ cars‚ dishwashers‚ or microwaves. In fact if one could travel back in time and see what it was they might think they were sent to some other planet. All of the advancements have improved human civilization and helped people move forward. Life today is much better than it was back in

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

When a tornado forms or passes over a water surface‚ it is called a waterspout. Like tornadoes‚ they form in many shapes and often occur in series or families. Measurements of tornadoes can be a few kilometers an hour to as high as 64 to 80 kilometers per hour. We should know what to do before‚ during‚ and after a tornado has hit our town. Tornados cause much damage and we people should be prepared before a tornado‚ during a tornado and what to do after a tornado. Before a tornado‚ we should listen
