Nanostructured and advanced materials for applications in sensor, optoelectronic and photovoltaic technology ; Proceedings of the NATO Advanced Study Institute on nanostructured and advanced materials for applications in sensors, optoelectronic and photovoltaic technology ; Sozopol, Bulgaria, 6-17 September 2004

Nanotechnology is an emerging scientific field receiving significant worldwide attention. On a nanometer scale, materials or structures may possess new and unique physical properties. Some of these are now known to the scientific community, but there may well be many properties not yet known to us, rendering it as a fascinating area of research and a suitable subject for a NATO ASI. Yet another aspect of the field is the possibility for creating meta-stable phases with unconventional properties and the ultra-miniaturization of current devices, sensors, and machines. Such nanotechnological and related advanced materials have an extremely wide range of potential applications, viz. nanoscale electronics, sensors, optoelectronics, photonics, nano-biological systems, na- medicine, energy storage systems, etc. This is a wide-ranging subject area and therefore requires the formation of multi-disciplinary teams of physicists, chemists, materials scientists, engineers, molecular biologists, pharmacologists, and others to work together on the synthesis and processing of materials and structures, the understanding of their physical properties, the design and fabrication of devices.

Modern architecture and climate design before air conditioning

explores how leading architects of the twentieth century incorporated climate-mediating strategies into their designs, and shows how regional approaches to climate adaptability were essential to the development of modern architecture. Focusing on the period surrounding World War II'before fossil-fuel powered air-conditioning became widely available'Daniel Barber brings to light a vibrant and dynamic architectural discussion involving design, materials, and shading systems as means of interior climate control. He looks at projects by well-known architects such as Richard Neutra, Le Corbusier, Lúcio Costa, Mies van der Rohe, and Skidmore, Owings, and Merrill, and the work of climate-focused architects such as MMM Roberto, Olgyay and Olgyay, and Cliff May. Drawing on the editorial projects of James Marston Fitch, Elizabeth Gordon, and others, he demonstrates how images and diagrams produced by architects helped conceptualize climate knowledge, alongside the work of meteorologists, physicists, engineers, and social scientists. Barber describes how this novel type of environmental media catalyzed new ways of thinking about climate and architectural design.

Micrometeorites and the Mysteries of Our Origins

This book relates an attempt to decrypt the still-obscure first billion years of history of the young Earth, during a cataclysmic period during which our planet was heavily bombarded by bodies ranging in size from that of Mars to 0.1 mm sized tiny micrometeorites. It was thus found that micrometeorites played an essential role in the formation of the post-lunar atmosphere. They also provided a surprisingly large diversity of reactions in the organic prebiotic chemistry required for the birth of life on our blue planet. The author presents a wide-ranging review of the type of knowledge required to decrypt this history, which provides extensive background information from astronomy, planetary dynamics, planetology, astrobiology and earth sciences. This book will appeal to both the scientist and the general reader. It will be a source of material for lectures, and possibly new investigations, in these fields.

Microbiology of Extreme Soils

This volume provides an excellent introduction to the study of extreme soil micro-biology, and a variety of the challenging and fascinating environments that Earth-bound microbes face. Some are natural, and some are the result of human activity, and all of them have lessons to teach us about life’s adaptations within the “extreme” hori-zons of terrestrial soils. What’s more, each of these chapters (including the chapter on the soils of Mars by Ronald L. Crawford and David A. Newcombe) can give us insights into strategies that may make life possible beyond the safe confines of our present-day biosphere, to other worlds in this solar system and beyond

Microbial Activity in the Rhizosphere

The rhizosphere is a very complex environment in which the effects of the plant on soil microorganisms and the effects of the microorganisms on the plant are interacting and are interdependent. Plant root exudates and breakdown products attract microbes and feed them and, in turn, the plants often benefit from the microbes. Interactions among microorganisms and plant roots are essential for nutritional requirements of the plant. Plant growth, development and productivity are largely dependent on the soil environment in the root region rhizosphere. The new techniques of studying the rhizosphere enables us to get a much better understanding of the dynamics of the rhizosphere population, such rhizosphere studies being of interest to agriculturists, soilbiologists, chemists, microbiologists and molecular biologists. The rhizosphere microbes in?uence the root environment in several ways. They may change the oxidation-reduction potential, influence the availability of moisture and nutrients, produce growth inhibiting or growth promoting substances in the form of exudates, provide competition and possibly induce many other effects. My corrhizal associations are beneficial in mineral uptake and in increasing root surface area for effective ion absorption. Antagonism, ompetition and synergism in soil and the rhizoplane (rhizosphere) are the most important microbial interactions to consider in the study of rhizosphere biology. With the growing information on the production of growth regulators, competitiveness of the microbes in the rhizosphere, microsymbionts, and other factors, their effect upon plant growth will become more evident. Experiments on the introduction of microbes or their products in the rhizosphere will help to improve our understandingofthebiologyoftherhizosphere.

Membrane Trafficking in Viral Replication

The ability of viruses to exploit cellular functions for their own ends makes them highly effective pathogens and exquisite experimental tools. Work with viruses underpins much of our current understanding of molecular cell biology and related fields. Each of the eight chapters in this volume deals with a specific aspect of viral interactions with cellular membranes. These include chapters on viral entry, viral membrane fusion, viral membrane protein synthesis and transport, viral replication, viral interactions with cytoskeletal systems and the nucleus, the trafficking of viral membrane proteins and viral perturbation of host cell protein trafficking. These chapters should provide both an overview of cellular membrane trafficking mechanisms and viral interactions with these systems, as well as reviews of the current state of each of the fields.

Integrated Urban Water Resources Management

Growing populations and rising standards of living exert stress on water supply and the quality of drinking water. In wastewater management, new challenges are caused by new chemicals of concern, including endocrine disrupters, pharmaceuticals, hormones, and personal care products, which often pass through wastewater treatment plants unabated, but may cause serious impacts on receiving aquatic ecosystems. Advanced wastewater treatment leads to production of biosolids, which are processed in various ways, including on-land applications in agriculture. Municipal effluents, combined with increasing withdrawals of water, lead to the worsening of receiving water quality. Expert opinions indicate that the only way to deal with the current urban water management dilemmas is by integrated management and innovative delivery of water services. This book presents important aspects of Challenges in Management of Urban Water Resources, Challenges in Urban Water Supply, Urban Drainage and Water Bodies, Wastewater Treatment and Security, and Wastewater Treatment and Reuse.
