Abstract

The first thing that will strike you about this issue is its rather large size, which has been the result of three times larger number of Science abstracts compared to the immediately preceding issue IJTS 6(2). We could not carry over some of these abstracts because the next special issue will be quite bulky as it will contain all the abstracts of research papers presented at OCHA 2007 held in November 2007. Presented below is a summary of the three papers published here, with editorial comments.
