  • The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind.[26] The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000 BC;[27] scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.

  • When students start an undergraduate course in engineering, they experience a step change in the level of complexity of the materials that had to be learned. Fluid Mechanics is one such module taught in the first year of the engineering undergraduate courses. It is a core module for Chemical, Mechanical and Civil engineers. The concepts may seem difficult and hard to grasp at the first instance but as the knowledge broadens, one may find it fascinating. This book is a collection of lecture notes developed from a series of lectures delivered to first year Chemical Engineers.

  • Recently public attention has turned toward the intricate interrelation between economic growth and global warming. This book focuses on this nexus but broadens the framework to study this issue. Growth is seen as global growth, which affects the global environment and climate change. Global growth, in particular high economic growth rates, implies a fast depletion of renewable and nonrenewable resources. Thus the book deals with the impact of economic growth on the envi- ronment and the effect of the exhaustive use of natural resources as well as the reverse linkage.

  • We prove the existence of dynamical delocalization for random Landau Hamiltonians near each Landau level. Since typically there is dynamical localization at the edges of each disordered-broadened Landau band, this implies the existence of at least one dynamical mobility edge at each Landau band, namely a boundary point between the localization and delocalization regimes, which we prove to converge to the corresponding Landau level as either the magnetic field goes to infinity or the disorder goes to zero. ...

  • .RISK Recent events from the economic downturn to climate change mean that there has never been a better time to be thinking about and trying to better understand the concept of risk. In this book, prominent and eminent speakers from fields as diverse as statistics to classics, neuroscience to criminology, politics to astronomy, as well as speakers embedded in the media and in government, have put their ideas down on paper in a series of essays that broaden our understanding of the meaning of risk.

  • • There is need to diversify urban-development activities within the municipality. An outward spread of these development activities and the creation of satellite towns in areas such as Olkaria, Sulmac and Sharlimar would minimise the pressure on the natural environment, land, forests, air and water resources, as well as on the capacities of socio-economic infrastructures such as sewerage and water supply facilities and roads. This will also result in a reduction of land use conflicts, which is a major cause of environmental degradation in any given urban scenario. ...

  • The history of science shows many close connections between physics and astronomy. It is well known that a number of physical laws evolved from a base of astronomical observations. For example, Kepler observed and, later Newton derived, the laws of gravitation while studying the motion of planets and their satellites. The existence of thermonuclear energy was solidly established when it explained the energy balance of the Sun and stars.

  • In writing a volume of this kind, one becomes keenly aware that science is indeed a community of scholars. We stand on the shoulders of giants, and mistake the broadened vision for our own. In this instance the giants are Kurt Lewin, George Herbert Mead, Sigmund Freud, William I. and Dorothy S. Thomas, Edward C. Tolman, Lev Vygotsky, Kurt Goldstein, Otto Rank, Jean Piaget, and Ronald A. Fisher. ·From these I learned mainly by reading. There are others who struggled to teach me, often against resistance. Chief among them were my first teachers in psychology, Frank S. Freeman, Robert M.

  • Ecosystem accounts are being developed as part of the System of Environmental-Economic Accounts which aims at supplementing the UN System of National Accounts with information on the environment and natural capital. The purpose is to broaden the scope of the variables taken into account in policymaking in order to improve understanding of the interdependence and interactions between the economy and the environment.

  • A major focus of current work in distributional models of semantics is to construct phrase representations compositionally from word representations. However, the syntactic contexts which are modelled are usually severely limited, a fact which is reflected in the lexical-level WSD-like evaluation methods used.

  • This paper begins with looking to changes in the definition of marketing. It traces marketing's expansion from a discipline concerned with business transactions in an economic market place, through a discipline concerned with any organisation that can be said to have customers, to a discipline concerned with all organisations in their relationships with all their publics, not just their customers.

  • The theory of Yin-Yang holds that the world is material and that this material world evolves constantly as the result of the mutual action of two opposing material forces. What is Yin-Yang? At its origin, the terms were used to designate the two slopes of a mountain. The sunny side was Yang and the shady side was Yin. Later, their meaning broadened to include all opposites.

  • For the last 60 or so years the chemotherapy of bacterial infections has been dominated by natural products and their semi-synthetic variants. Although the term antibiotic was initially used exclusively to describe those anti-bacterials of natural or semi-synthetic origin, it has become broadened in common usage to include antibacterial agents of purely synthetic origin as well. The emphasis of this chapter will be on the discovery of novel prototype structures that represent the different classes of antibiotic e.g.

  • The Bank plans to include a page of environmental indicators in Country Assistance Strategies — the documents drawn up to guide policy discussion with each client country — as well as in its cross-country analytical work. A key figure that is likely to guide Bank decision-makers, and by extension, policy-makers in many countries, is the new concept of “genuine savings”. Genuine savings figures aim to denote the rate at which national wealth (broadened to include human capital, and natural capital) is being created or destroyed.

  • Programs that can assist in the creation or automatically create trip diaries and stories will considerably increase use, especially for future viewers who have no idea of the content. For example, a fishing trip diary with a timeline, animated maps and annotations is substantially more valuable to us and our progeny than a collection of unlabelled photos in a labeled folder. New capture devices vastly broaden the nature of personal recording.

  • This publication sheds light on the issue of decentralisation in Mexico. It shows that decentralisation can make decision-making more efficient and increase local participation in development issues. Decentralisation can provide a better framework to improve local infrastructure and to channel the necessary finance from public and private sources. The modernisation of infrastructure systems in Mexico's cities and regions would improve the quality of life and stimulate economic development, thus fostering entrepreneurship and employment.

  • Site-directedmutagenesis was used to investigate the control of 2-oxoacid cosubstrate selectivity by deacetoxycephalo-sporin C synthase. The wild-type enzyme has a requirement for 2-oxoglutarate and cannot efficiently use hydrophobic 2-oxoacids (e.g. 2-oxohexanoic acid, 2-oxo-4-methyl-penta-noic acid) as the cosubstrate. The followingmutant enzymes were produced: R258A, R258L, R258F, R258H and R258K. All of the mutants have broadened cosubstrate selectivity and were able to utilize hydrophobic 2-oxoacids.
