Abstract

Computed tomographic images were generated using collimated microwaves of frequency 10.5 GHz instead of x rays. In the authors' laboratory version of a rotate-translate scanner, the beam is fixed and a phantom is moved between source and detector, the apparatus being suspended in a tank of fluid to provide impedance matching between phantom, source, and receiver. Phantoms consisting of test tubes of water, cylinders of wood, and animal tissues show spatial resolutions of about 2 cm. It is planned to apply the technique first to mammographic examination, which can best utilize the large difference in microwave absorption between fatty and nonfatty tissues.

Evaluation of sites for the location of WEEE recycling plants in Spain.

As a consequence of new European legal regulations for treatment of waste electrical and electronic equipment (WEEE), recycling plants have to be installed in Spain. In this context, this contribution describes a method for ranking of Spanish municipalities according to their appropriateness for the installation of these plants. In order to rank the alternatives, the discrete multi-criteria decision method PROMETHEE (Preference Ranking Organisation METHod for Enrichment Evaluations), combined with a surveys of experts, is applied. As existing plants are located in North and East Spain, a significant concentration of top ranking municipalities can be observed in South and Central Spain. The method does not present an optimal structure of the future recycling system, but provides a selection of good alternatives for potential locations of recycling plants.

Overview of informatics for high content screening.

With the growing use of high content screening (HCS) and analysis in drug discovery and systems biology, informatics has come to the forefront as a critical technology to effectively utilize the massive volumes of high content data and images being generated. Informatics technologies are required to transform HCS data and images into useful information and then into knowledge to drive decision making in an efficient and cost effective manner. In this chapter, we provide an overview of informatics tools and technologies for HCS, discuss some of the challenges of harnessing the huge and growing volumes of HCS data, and provide insight to help toward implementing or selecting, and utilizing a high content informatics solution to meet your organization's needs.
