Growing stockpiles of nuclear weapons grade fissile materials (plutonium and highly enriched uranium) are a "clear and present danger" to international security. Much of this material is uncontrolled and unsecured in the former Soviet Union (FSU). Access to these materials is the primary technical barrier to a nuclear weapons capability since the technology know-how for a bomb making is available in the world scientific community. Strategies to convince proliferators to give up their nuclear ambitions are problematic since those ambitions are a party of largest regional security. There is no national material control and accounting in Russia. No one knows exactly how much fissile materials they have, and if any is missing. A bankrupt atomic energy industry, unpaid employees and little or no security has created a climate in which more and more fissile materials will likely be sold in black markets or diverted to clandestine nuclear weapons programs or transnational terrorist groups. Control over these materials will ultimately rely on the continuous and simultaneous exercise of several measures. While there is little one can do now to stop a determined proliferator, over time international consensus and a strengthened non-proliferation regime will convince proliferators that the costs outweigh the gains.
Currently Drosophila is a dominant experimental model in developmental biology and in gene regulation in eukaryotes. This volume summarizes some thirty years of experience in the handling of in vitro cultured Drosophila cells. Its main emphasis is on gene transfer methodology, cell responses to heat shock, hormonal regulation of genes, and on the expression and mobility of transposable elements. - Some thirty years of experience in handling in vitro cultured Drosophila cells - Cell cultures which provide material for a multiplicity of biochemical approaches - DNA-mediated gene transfer as an irreplaceable tool for analyzing basic mechanisms of regulation - Drosophila cell lines which qualify them for use in biotechnology
As in previous editions, this book approaches the study of child development from an inside/outside perspective, looking at children from an abstract or research-based point of view as well as from a personal or experiential perspective. The ''whole child'' is addressed at each stage of development in a chronological format with each stage presenting physical, cognitive, social, and emotional facets of the child. Strong coverage of research, theory, and issues in developmental psychology is augmented with examples to show their implications to students.
