The purpose of this study was to evaluate the effect of different frequencies of pulsed electromagnetic fields on the osteogenic differentiation of human mesenchymal stem cells. Third-generation human mesenchymal stem cells were irradiated with different frequencies of pulsed electromagnetic fields, including 5, 25, 50, 75, 100, and 150 Hz, with a field intensity of 1.1 mT, for 30 minutes per d...

An explosive ordnance is a munition that is either launched or fired with the intent of detonation at a specified target. An unexploded ordnance (UXO) is an explosive ordnance that, due to some malfunction, remains undetonated. As a result, the ordnance can be found at the ground surface, partially buried, or buried at a depth of up to 8 m beneath the surface. Practical and cost-effective strat...

A coil-gun uses pulsed currents of large magnitude to propel ferrous projectiles at high speeds. The various problems associated with high currents and magnetic fields are discussed, as well as the components and design of my experimental coil-gun. I tested the coil-gun at various charge voltages and different projectile sizes, then calculated the efficiency of the coil-gun with measured values...

An estimated 110 million landmines, mostly antipersonnel mines laid in over 60 countries, kill or maim over 26 000 people a year. One of the dilemmas for removing landmines is the amount of false alarms in a typical minefield. Broadband electromagnetic induction spectroscopy (EMIS) is a promising technology that can both detect and identify buried objects as landmines. By reducing the number of...

Electromagnetic induction imaging has wide potential application in the disciplines of medicine, security, industry, geophysics and scientific research in general. The present study focuses on the applications in the security industry and in particular on providing a new tool for cargo screening in the context of the detection of illicit trafficking of special nuclear materials. The thesis repo...

The use of electromagnetic ~EM! induction measurements was evaluated to predict water content in the upper 1.50 m of a prototype engineered barrier soil profile designed for waste containment. Water content was monitored with a neutron probe, and bulk soil electrical conductivity was monitored with a Geonics EM38 ground conductivity meter at ten locations at approximately monthly intervals over...
