Taschenbuch. Condizione: Neu. Neuware - The Occupational Safety and Health Administration (OSHA) has updated their recordkeeping requirements for the first time since 1971. This results in a significant number of changes for every employer with ten or more employees, which can often cause confusion and failure to comply. OSHA 2002 Recordkeeping Simplified goes beyond the explanation that OSHA supplies to provide an easy understanding of these new requirements.

Buch. Condizione: Neu. Neuware - This book is a continuation of 'Acoustic and Elastic Wave Fields in Geophysics, Part I' published in 2000. The second volume is dedicated to propagation of linear plane, spherical and cylindrical acoustic waves in different media. Chapter 1 is devoted to principles of geometric acoustic in plane wave approximation. The eikonal and transport equations are derived. Ray tracing and wavefront construction techniques are explained. Chapter 2 deals with dynamic properties of wave fields. The behavior of pressure and displacements amplitudes in zero approximation is analysed in two ways: using Poynting vector and solving the transport equation. This chapter contains several examples related to shadow zones and caustics. In Chapter 3 using the results of analysis of high-frequency wave kinematics and dynamics some fundamental aspects of Kirchhoff migration are described. Chapters 4 and 5 are devoted to propagation of plane waves in media with flat boundaries in the case of normal and oblique incidence. Special attention is paid to the case when an incident angle exceeds the critical angles. Formation of normal modes in the waveguide is discussed. Chapter 6 deals with a spherical wave reflection and refraction. The steepest descent method is introduced to describe the behavior of reflected, transmitted, head and evanescent waves. In Chapter 7 propagation of stationary and transient waves in a waveguide formed by a flat layer with low velocity are investigated. Normal modes and waves related to the branch points of integrands under consideration are studied. Dispersive properties of normal modes are discussed. Chapter 8 describes wave propagation inside cylinder in acoustic media. Several appendices are added to help the reader understand different aspects of mathematics used in the book.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Periodic Table of the Elements is the most widely used basis for systematic discussion of inorganic chemistry. Two experienced chemists encapsulate their knowledge and teaching experience in this succinct text, suitable for both undergraduate and post-graduate courses. Part one explains how fundamental properties of atoms determine the chemical properties of elements, and how and why these properties change in the Periodic Table. The main properties discussed include radii and energies, ionization potentials, and electron affinities. Particular emphasis is placed on unique properties of the first s, p, and d shells, on the effects of filled 3d and 4d shells on the properties of p and d elements, and on relativistic effects in the heavy elements. The overall treatment will clarify many complex concepts. Part two presents an outline of inorganic chemistry within the framework of the Periodic Table, detailing the application and relevance of the principles set out in part one. 208 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The processes of manufacture and assembly are based on the communication of engineering information via drawing. These drawings follow rules laid down in national and international standards. The organisation responsible for the international rules is the International Standards Organisation (ISO). There are hundreds of ISO standards on engineering drawing because drawing is very complicated and accurate transfer of information must be guaranteed. The information contained in an engineering drawing is a legal specification, which contractor and sub-contractor agree to in a binding contract. The ISO standards are designed to be independent of any one language and thus much symbology is used to overcome any reliance on any language. Companies can only operate efficiently if they can guarantee the correct transmission of engineering design information for manufacturing and assembly.This book is a short introduction to the subject of engineering drawing for manufacture. It should be noted that standards are updated on a 5-year rolling programme and therefore students of engineering drawing need to be aware of the latest standards. This book is unique in that it introduces the subject of engineering drawing in the context of standards. 150 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mining the Web: Discovering Knowledge from Hypertext Data is the first book devoted entirely to techniques for producing knowledge from the vast body of unstructured Web data. Building on an initial survey of infrastructural issues-including Web crawling and indexing-Chakrabarti examines low-level machine learning techniques as they relate specifically to the challenges of Web mining. He then devotes the final part of the book to applications that unite infrastructure and analysis to bring machine learning to bear on systematically acquired and stored data. Here the focus is on results: the strengths and weaknesses of these applications, along with their potential as foundations for further progress. From Chakrabarti's work-painstaking, critical, and forward-looking-readers will gain the theoretical and practical understanding they need to contribute to the Web mining effort. 368 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A variety of complementary techniques and approaches have been used to characterize peptide and protein unfolding induced by temperature, pressure, and solvent. Volume 62, Unfolded Proteins, assembles these complementary views to develop a more complete picture of denatured peptides and proteins. The unifying observation common to all chapters is the detection of preferred backbone confirmations in experimentally accessible unfolded states. 398 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Chronobiology is the study of timing mechanisms in biological systems as diverse as plants, animals and some micro-organisms. It includes rhythmic phenomena ranging from short period (ultradian) through daily (circadian) to long period (monthly, annual) cycles of behaviour, physiology and biochemistry. In recent years spectacular advances have been made, particularly in the field of circadian rhythms, and hardly a week passes without important papers appearing in the major scientific journals.The third edition of Insect Clocks, like its predecessors, deals with the properties and functions of clock-like processes in one of the planet's most abundant groups of organisms. The first half of the book is concerned with circadian rhythmicity, the second with annual responses such as over-wintering diapause, seasonal morphs and cold hardiness. Insect Clocks puts modern developments in these fields into a secure framework of the 'classical' literature that has defined the subject.The book is directed at active researchers in the field as well as newcomers and scientists working in many other areas of modern biology. It will also serve as a textbook for advanced and less advanced students and should find its way into university libraries wishing to keep abreast of the times. 576 pp. Englisch.
