Terahertz frequency sensing has a unique part to play in the detection and identification of materials and objects. This frequency range, corresponding to a wavelength of around 0.1 mm, can be used to identify materials from their molecular spectra and to produce images of concealed objects. Terahertz spectra of drugs of abuse and explosives presented by a number of the contributing authors show that the presence of these materials can be detected in envelopes, packages and through clothing.
The technology of terahertz detection has largely been developed around expensive and bulky...

In case of security threats there is a need for temporal access to complete, updated, reliable information, in a dedicated form, is an essential prerequisite to effectively counter security threats. Currently the necessary information exists in a multitude of forms and formats geographically and physically scattered over different countries, institutes and organisations, and are subject to widely different data policies and management schemes. Moreover, there is no complete and updated overview of the existing information, e.g. in the form of a metadata catalogue. As a result, integration...

The assessment of land use and land cover is an important activity for cont- porary land management. Human land-use practices are the most significant factors influencing environmental management at local, regional, national, and global scales. In the past, environmental policies have often reflected a reactive response to environmental perturbations with management efforts focused on short-term, local-scale problems such as pollutant abatement. Currently, environmental management philosophy is evolving toward examination of critical environmental problems over larger spatial scales and...

Persistent organic pollutants (POPs) are organic compounds of natural or anthropogenic origin that resist photolytic, chemical and biological degradation. They are characterized by low water solubility and high lipid solubility, resulting in bioaccumulation in fatty tissues of living organisms. These properties of unusual high persistence and semi-volatility, coupled with other characteristics, have resulted in the presence of POPs all over the world, even in regions where they have never been used. With the evidence of long-range transport of these substances to regions, the international...

Since the end of the Cold War, the nuclear threats facing the world are dramatically evolving and have become even much more complex. However, the events of the past years have proved the necessity to reevaluate these threats on a level never before considered. The need to prevent, detect and respond to Nuclear/Radiological threats leads to many requirements that are not met by current scientific technologies and scientific communities.
For this concern now we are aware and recognize, the first, that no single institution (no single country) possesses all the required assets to...
