"SAS[superscript 2]: A Guide to Collaborative Inquiry and Social Engagement represents a groundbreaking international effort to support the creation and mobilization of practical, authentic knowledge for social change. The guiding principle behind SAS[superscript 2] (Social Analysis Systems, www.sas2.net) is that group dialogue and social inquiry are crucial for local and global development. Social issues must be addressed socially and in a multistakeholder mode, not by private interests and experts alone, and the insights that emerge fully integrated into processes of knowledge production, planning, and decision-making." "This book will be an invaluable resource for researchers, consultants, facilitators, and activists working with people to solve problems and support inclusive inquiry and decision-making. It will also be useful to scholars and academics studying and teaching participatory action research in the social sciences."--BOOK JACKET.

This book develops techniques for simulating digital logic circuits in Microsoft’s Excel that provide a useful tool to both the student and the practicing engineer. It introduces the subject by showing how logic devices, taken from the standard 7400 family, can be modeled and stored in a library. These functions can then be combined by the user as building blocks to design more complex circuits, both combinatorial and sequential. The simulations not only allow the designs to be verified to ensure they provide expected outputs and states, but can also perform detailed timing analysis. Worst case timing conditions can be imposed to stress the circuits so that the resultant behavior can be observed. Methods showing how the user can add additional devices to the simulation library are also covered.

From July 7 to 12, 2008 in Zelenogradsk, a cosy resort on the bank of the Baltic Sea near Kaliningrad in Russia, the 1st International Conference “Atmosphere, Ionosphere, Safety (AIS-2008)” has been carried out. The State Russian University of I. Kant, Semenov Institute of chemical physics of the Russian Academy of Sciences, Pushkov Institute of terrestrial magnetism and radio-waves propagation of the Russian Academy of Sciences, and Russian Committee on Ball Lightning (BL) have acted as organizers of the conference. Financial support was made by Russian Fund of Fundamental Research Project N. 08-03-06041 and European Of?ce of Aerospace Research and Development Grant award FA8655-08-1-5052. The International conference “Atmosphere, Ionosphere, Safety” (AIS-2008) was devoted to (i) the analysis of the atmosphere–ionosphere response on natural and man-made processes, the reasons of occurrence of the various accompanying geophysical phenomena, and an estimation of possible consequences of their in?uence on the person and technological systems; (ii) the study of the monitoring possibility and search of the ways for the risk level decrease. Discussion of the physical and chemical processes accompanying the observable geophysical p- nomena was undertaken. One can see from a list of the Conference sections that questions of safety took only rather modest place, so main topics of the Conference became discussion of processes taking place in the atmosphere, ionosphere and methods of monitoring these processes.

This work develops a set of advanced signaling concepts for IP-based networks. It proposes a design for secure and authentic signaling and provides QoS signaling support for mobile users. Furthermore, this work develops methods which allow for scalable QoS signaling by realizing QoS-based group communication mechanisms and through aggregation of resource reservations.

The field of DNA repair is vast and advancing rapidly. Recent investigations have begun to focus on the involvement of chromatin in the repair of broken DNA. Although I have no doubt that many breakthroughs in our understanding of chromatin, chromatin regulation, and DNA repair lie in our future, presently this is a new line in inquiry. As such there are many, many unanswered questions. Indeed, most of the correct questions have probably not even been asked yet. Here I have attempted to present a review of some of the current body of knowledge that may prove relevant to understanding the role of chromatin in DNA repair. Because the volume of research, and the relevant findings, come from a staggering array of labs, systems, and ideas I have focused primarily on findings developed from the study of the budding yeast Saccharomyces cerevisiae. Unfortunately, this means that I have left out a great deal of information. It is my hope, however, that the information I do detail, particularly in Chapter 1, will give a flavor for the scope of the problem and perhaps highlight some of the interesting directions this field is taking, or may one day take. I would also point out that the primary research that is presented herein is not in any way meant to represent the comprehensive scope of research being performed. To understand DNA repair will require investigation from innumerable labs, performed by innumerable researchers, moving in unexpected directions.

The lectures reported in these proceedings were given in the Workshop on Nuclear Reactors — Physics, Design and Safety held at the International Centre for Theoretical Physics in Trieste in 1994 by experts from leading international research institutions and industries. They have been organized in a self-consistent form with the objective of giving basic, up-dated information to scientists and engineers from developing countries in modern methods for the computation and analysis of nuclear reactors, with particular emphasis on reactor physics, design and safety.

An early view of eukaryotic chromosomes was that of static structures, which stored DNA not in use within a given cell type. It was thought that packaging of DNA into higher levels of chromatin structure would suffice to repress gene expression and that the challenge to the cell would be to rescue specific sequences from these structures. The exten sive packaging of inactive DNA was considered the primary difference between eukaryotic and prokaryotic genomes and except for that point both would be similarly regulated by cis-acting sequences and trans acting factors. Our view of eukaryotic chromosomes has evolved dra matically over the last decade. The picture of chromosomes that is emerging is that of dynamic breathing organelles actively regulating the flow of genetic information from the genome. Indeed chromatin is so fluid that even maintaining gene quiescence is an active process and is tightly regulated. Chromatin dynamics is a consequence of protein complexes that modify histones, remove histone modifications, mobi lize nucleosomes or stabilize nucleosomes. Awide variety of such com plexes have now been described. Some are abundant and may play glo bal roles in chromosome fluidity and function. Others are more rare and specialized for specific functions at discreet loci. Moreover, several complexes share biochemical activities and genetic studies suggest overlapping functions in vivo. Many components of these complexes were first revealed in genetic screens, while others were discovered by novel cell biological or biochemical approaches.
