  • The Encyclopedia of Soils in the Environment is a vitally important scientific publication and an equally important contribution to global public policy. The Encyclopedia brings together a remarkable range of cutting-edge scientific knowledge on all aspects of soil science, as well as the links of soils and soil science to environmental management, food production, biodiversity, climate change, and many other areas of significant concern.

  • The extraordinary ability of the chemical element carbon to combine with itself and other chemical elements in different ways is the basis of organic chemistry and of life. This chemical versatility also gives rise to a rich diversity of structural forms of solid carbon. This introductory chapter is an attempt to survey the very wide range of carbon materials that is now available with emphasis on chemical bonding and microstructure.

  • The micro- and nano- transport of biomolecules is of interest to a wide range of scientific and engineering communities. Application areas include miniaturized technology that will support and advance key sectors, including healthcare, food provisioning, environment services, etc. This ebook is generally intended for undergraduate students from chemical, life and physical sciences wanting to find out about the basic properties of biomolecules and how they can be transported in liquids on the micro- to nano-scale.

  • For more than 30 years there has been remarkable growth in the need for quality water purification by all categories of users – municipal, industrial, institutional, medical, commercial and residential. The increasingly broad range of requirements for water quality has motivated the water treatment industry to refine existing techniques, combine methods and explore new water purification technologies.

  • Overharvesting has led to severe reductions in the abundance and range of nearly every large vertebrate species that humans have ever found worth pursuing. These megafaunal reductions, dating in some cases from first contact with early peoples (Martin 1973), are widely known. In contrast, remarkably little is known about the ecological consequences of megafaunal extirpations. Whales and whaling are part of that legacy. Most people know that large whales have been depleted, but little thought has been given to how the depletions may have influenced ocean ecosystems.

  • On 21 March 1990 John Hammersley celebrates his seventieth birthday. A number of his colleagues and friends wish to pay tribute on this occasion to a mathematician whose exceptional inventiveness has greatly enriched mathematical science. The breadth and versatility of Hammersley’s interests are remarkable, doubly so in an age of increased specialisation. In a range of highly individual papers on a variety of topics, he has theorised, and posed (and solved) problems, thereby laying the foundations for many subjects currently under study.

  • We prove that Cayley graphs of SL2 (Fp ) are expanders with respect to the projection of any fixed elements in SL(2, Z) generating a non-elementary subgroup, and with respect to generators chosen at random in SL2 (Fp ). 1. Introduction Expanders are highly-connected sparse graphs widely used in computer science, in areas ranging from parallel computation to complexity theory and cryptography; recently they also have found some remarkable applications in pure mathematics; see [5],[10], [15], [20], [21] and references therein. ...

  • For over three months No. 3 Squadron had been occupied daily in ranging the heavy guns which night after night crept into their allotted positions in front of Albert. On July 1st 1916 the Somme offensive opened with gas and smoke and a bombardment of unprecedented severity. To the pilots and observers in an artillery squadron the beginning of this battle brought a certain relief, for we were rather tired of flying up and down, being shot at continually by fairly accurate and remarkably well hidden anti-aircraft batteries, while we registered endless guns on uninteresting points.

  • This book captures the experiences and voices of over 6,000 people who have received international assistance, observed the effects of aid efforts, or been involved in providing aid. Over time, across very different contexts and continents, people’s experiences with international aid efforts have been remarkably consistent. While there was a wide range of opinions on specifics, the authors were struck by the similarity in people’s descriptions of their interactions with the international aid system.

  • In both groups (patients with epilepsy and healthy controls) we used a questionnaire Epworth Scale of Sleepiness (ESS) (Johns, 1991). By answering eight questions about probability of falling asleep in standard situations we came to the result, i.e. score of daytime sleepiness ranging from 0 to 24. Rate 0-9 is considered as normal value, above 9 as elevated daytime sleepiness and value above 16 is considered as remarkably elevated daytime sleepiness (Watanabe et al., 2003).

  • Temperature has a strong influence on most individual biochemical reac-tions. Despite this, many organisms have the remarkable ability to keep certain physiological fluxes approximately constant over an extended tem-perature range. In this study, we show how temperature compensation can be considered as a pathway phenomenon rather than the result of a single-enzyme property.

  • The ring-hydroxylating dioxygenase (RHD) from Sphingomonas CHY-1 is remarkable due to its ability to initiate the oxidation of a wide range of polycyclic aromatic hydrocarbons (PAHs), including PAHs containing four- and five-fused rings, known pollutants for their toxic nature.

  • This work models Word Sense Disambiguation (WSD) problem as a Distributed Constraint Optimization Problem (DCOP). To model WSD as a DCOP, we view information from various knowledge sources as constraints. DCOP algorithms have the remarkable property to jointly maximize over a wide range of utility functions associated with these constraints. We show how utility functions can be designed for various knowledge sources.

  • In this opening chapter, we outline some of the most influential (and most contested) definitions of health, and approaches to health promotion. Although some success has been claimed for health promotion interventions, in general the results to date have been modest: for example, safer sex campaigns in preventing HIV infection among gay men. In other areas efforts have been remarkably disappointing, notably in preventing smoking uptake among adolescents. ‘Health promotion’ is a term which has been applied to a very wide range of activities performed in many and diverse contexts....
