Book Description
Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased. The book spans a broad spectrum of Antarctic science from the "ozone hole" to microbiology to the sea ice. The main focus is on the role of Antarctica and the Southern Ocean in the world climate system, e.g. the formation of sea ice and its relevance to ocean circulation, the biological pump in relation to CO2 release. The past climate history is revealed by the analysis of ice cores and sediments. Studies of plate tectonics and fossil records reach further back in earth history. Key words in the biological chapters are krill and the rich Antarctic benthos. Finally, the potential conflict between conservationists, researchers and tourists is discussed.

Book Description
In this hardbound edition of the 7th novel in the series, the planet Pluto suddenly disappears. There one minute and gone the next. Is this the start of an invasion? Tom Swift is called upon to investigate. For starters he agrees to refurbish and move the long-defunct Hubble Space telescope into a position where it might scan the now empty area. Finding nothing he builds an ultra fast space probe. But when that disappears as it nears the missing planet's position, it raises even more questions. A second probe is flung far to one side. The only thing to do is to go out himself, and so Tom sets about building a new, giant and incredibly fast spaceship, The Sutter. Before he can launch it, Pluto or something slightly larger reappears and begins heading inward toward the Sun. The problem is that the Earth is in the way. If Tom can't deflect this paradox planet from its course, all mankind might perish. But what secrets can this planet hold? And, why does it suddenly slow down inside Jupiter's orbit?

Book Description
The Archive of Place weaves together a series of narratives about environmental history in a particular location � British Columbia's Chilcotin Plateau. In the mid-1990s, the Chilcotin was at the centre of three territorial conflicts. Opposing groups, in their struggle to control the fate of the region and its resources, invoked different understandings of its past � and different types of evidence � to justify their actions. These controversies serve as case studies, as William Turkel examines how people interpret material traces to reconstruct past events, the conditions under which such interpretation takes place, and the role that this interpretation plays in historical consciousness and social memory. It is a wide-ranging and original study that extends the span of conventional historical research.

Book Description
Prior to 1979, consideration of the problem of the carcinogenicity of the aromatic amine class of chemicals took place primarily in poster sessions and symposia of annual meetings of the American Association for Cancer Research and analogous international associations. In November 1979 the first meeting concerned with the aromatic amines was held in Rockville, Haryland under primary sponsorship of the National Cancer Institute. The proceedings from this meeting were published as Monograph 58 of the Journal of the National Cancel' Institute in 1981. The second meeting in this series, the Second International Conference on N-Substituted Aryl Compounds, was held in March/April of 1982 in Hot Springs, Arkansas. The National Cancer Institute and The National Center for Toxicological Research were the primary sponsors of this meeting. The proceedings were published as Volume 49 of the journal En-vil'onmental Health Perspectives in 1983. The third meeting in this series was held in April of 1987 at the Dearborn Hyatt in Dearborn, Michigan. The principal sponsor of this meeting was the Heyer L. Pre ntis Comprehensive Cancer Center of Metropolitan Detroit. The proceedings, Carcinogenic and Mutagenic Responses to Aromatic Amines and Nitroal'enes, were published in 1987 by Elsevier Press. The fourth meeting was held in Cleveland, Ohio, on July 15-19, 1989.

Book Description
The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates. This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming and (in lamnid sharks) may even aid in energy conservation. However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.

Book Description
As Africa urbanises and the focus of poverty shifts to urban centres, there is an imperative to address poverty in African cities. This is particularly the case in smaller cities, which are often the most rapidly urbanising, but the least able to cope with this growth. This book argues that an examination of the food system and food security provides a valuable lens to interrogate urban poverty. Chapters examine the linkages between poverty, urban food systems and local governance with a focus on case studies from three smaller or secondary cities in Africa: Kisumu (Kenya), Kitwe (Zambia) and Epworth (Zimbabwe). The book makes a wider contribution to debates on urban studies and urban governance in Africa through analysis of the causes and consequences of the paucity of urban-scale data for decision makers, and by presenting potential methodological innovations to address this paucity. As the global development agenda is increasingly focusing on urban issues, most notably the urban goal of the new Sustainable Development Goals and the New Urban Agenda, the work is timely.

Book Description
Rule of law has vanished in America’s criminal justice system. Prosecutors decide whom to punish; most accused never face a jury; policing is inconsistent; plea bargaining is rampant; and draconian sentencing fills prisons with mostly minority defendants. A leading criminal law scholar looks to history for the roots of these problems—and solutions.
