  • Colloid and surface chemistry occupy a paradoxical position among the topics of physical chemistry. These are areas which have traditionally been considered part of physical chemistry and are currently enjoying more widespread application than ever due to their relevance to environmental and biological problems. At the same time, however, colloid and surface chemistry have virtually disappeared from physical chemistry courses. These topics are largely absent from the contemporary general chemistry course as well.

  • “Just do an Internet search.” “It’s on the Internet.” How often have we said or been told that we could find it on the Internet. This third edition of The Water Encyclopedia: Hydrologic Data and Internet Resources started from a premise that most of the information provided within this publication could be found on the Internet. As our team of contributing authors started reviewing each section within each chapter, it soon became apparent that you cannot always find it on the internet.

  • The genesis of this book began on the sunny shores of southern France in September 1993. For five days in the delightful Mediterranean coastal town of La Londe Les Maures, a gathering occurred of a group of scientists interested in furthering both the understanding and use of thermal infrared (TIR) remote sensing data for analysis of land surface processes.

  • This paper addresses a data-driven surface realisation model based on a large-scale reversible grammar of German. We investigate the relationship between the surface realisation performance and the character of the input to generation, i.e. its degree of underspecification. We extend a syntactic surface realisation system, which can be trained to choose among word order variants, such that the candidate set includes active and passive variants.

  • The pH values will bring effects in flora and fauna nearby, change the taste of water and lead to heavy corrosion in pipe lines. High conductivity naturally indicates the presence of ionic substances dissolved in the river water. However, the result showed that 90% of the study site exceeded the data reported for non-contaminated rivers due to excessive metal ions within the water. At the site nearer to kaolin industry the conductivity is 852 times higher than the non-polluted study site. The industrial discharge also changed the hardness in river water.

  • In the book "Chemometrics in practical applications", various practical applications of chemometric methods in chemistry, biochemistry and chemical technology are presented, and selected chemometric methods are described in tutorial style. The book contains 14 independent chapters and is devoted to filling the gap between textbooks on multivariate data analysis and research journals on chemometrics and chemoinformatics.

  • Storage devices hold data, even when the computer is turned off. The physical material that actually holds data is called a storage medium. The surface of a floppy disk is a storage medium. The hardware that writes data to or reads data from a storage medium is called a storage device. A floppy disk drive is a storage device. The two primary storage technologies are magnetic and optical.

  • The EU Water Framework Directive (2000/60/EC) is probably the most significant legislative instrument in the water field that was introduced on an international basis for many years. It moves towards integrated environmental management with key objectives to prevent any further deterioration of water bodies, and protect and enhance the status of aquatic ecosystems and associated wetlands. It aims to promote sustainable water consumption and will contribute to mitigating the effects of floods and droughts.

  • This book is designed as a supplementary text for upper division under- graduate and graduate real estate investment courses. The CD-ROM included with the book contains spreadsheets for data analysis tailored specifically to real estate settings. The major thrust is to bridge the gap between theory and practice by showing the student how to implement his real estate education in the real world. The study of real estate follows long traditions grounded in Urban Economics and Finance.

  • Written by a premier astronomy expert, this book begins with a discussion of the Sun, from sunspots to solar eclipses. It then features over 100 tables on characteristics of the Moon, and the names, positions, sizes, and other key descriptors of all the planets and their satellites. The book tabulates solar and lunar eclipse, comets, close-approach asteroids, and significant meteor showers dates. Twenty-four maps show the surface features of the planets and their moons. The author then looks to the stars, their distances and movements, and their detailed classification and evolution.

  • Environmental accounting is a term with a variety of meanings. In many contexts, environmental accounting is taken to mean the identification and reporting of environment- specific costs, such as liability costs or waste disposal costs. For the purposes of this analysis, a much more general definition is used. "Environmental accounting" is more than accounting for environmental benefits and costs. It is accounting for any costs and benefits that arise from changes to a firm's products or processes, where the change also involves a change in environmental impacts.

  • Breaking waves on the sea cause the ejection of many tiny droplets of seawater into the atmosphere. These droplets dry by evaporation leaving sea salt particles suspended in the air. Particles are also directly emitted by the bursting of air bubbles on sea surface Such particles are generally in the size range between 1 to 20µm. [19]. Whilst these particles are, in the main, rather coarse in size, a minor part of their mass is in particles small enough to have an appreciable atmospheric lifetime, which has been estimated as three days [20].

  • In this paper, we focus our attention on providing a formal framework for expressing data mining tasks in- volving time granularities, and on proposing efficient algo- rithms for performing such tasks. To this end, we introduce the notion of an event structure. An event structure is essen- tially a set of temporal constraints on a set of variables representing events. Each constraint bounds the distance between a pair of events in terms of a time granularity.
