− The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in substance and also boundary phenomena by means of Fresnel’s reflection and transmission coefficients. The interaction between electromagnetic radiation and infinite plane shield having finite thickness d, placed in free space in plane waves region depends of material/shi...

The new materials in public art installations give the birth to interactivity and participation, which in turn, introduces new challenges, not only in the creative design process, but also in how to involve the participants in this process and in evaluating the targeted experience such as such as social connectedness and inclusion. Six design cases are presented, as examples for interactive and...

The collection, processing and certification of a new sediment Standard Reference Material (SRM), SRM 2704, is described. Collected from the bottom of the Buffalo River in New York State during the fall of 1986, SRM 2704 is certified for 25 elements with information provided on another 22 elements. Improvements in analytical methods as well as the application of well-defined quality-control pro...

The purpose of this study was to analyze the physical properties and chemical compositions of a new experimental cement (NEC) and compare them with mineral trioxide aggregate (MTA); pH, working time, setting time, dimensional changes following setting, flow, film thickness, and chemical composition of NEC and MTA were assessed. For chemical compositions, all specimens were imaged and analyzed b...

In the last 50 years, very many new energetic compounds have been made as potential ingredients for explosive, propellant and pyrotechnic formulations. Of these compounds very few have come to be used in military munitions. To obtain a better understanding of why this has been the case and to help address the discrepancy, the NATO Insensitive Munitions Information Centre (NIMIC) held a workshop...
