Buch. Condizione: Neu. Neuware - Over the past decade the topic of emissions reduction and control has remained an important area of research due to the enforcement of various Government policies in an attempt to minimize the impact on the environment. One area in which a great deal of research has been conducted to address this policy is NOx/SOx suppression. However, despite the progress that has been made over this time period, further research into the most effective method of reducingNOx/SOx emissions is still urgently required. In developed countries, a more stringent requirement in the level of emissions (such as is NOx/SOx component of less than 10ppm) will be enforced in the near future. Developing countries will also need a new technology that is effective and that is suited to each countries needs. Additional research and development efforts are thus necessary to meet such requirements.

Buch. Condizione: Neu. Neuware - This compendium contains a collection of key papers from the journal Energy Policy, offering a valuable reference point on the role of flexibility mechanisms in the mitigation of climate change. Originally published between December 1999 and August 2001, all of these articles concern particular aspects of the Kyoto mechanisms or variations on the theme of flexibility that have evolved elsewhere.

Buch. Condizione: Neu. Neuware - Gas phase ion chemistry is a broad field that has many applications and which encompasses various branches of chemistry and physics. Advances in Gas Phase Ion Chemistry, Volume 4, describes innovative ways of studying reactions as well as the application of unique apparatuses to problems in this field. This volume contains a series of chapters, in the general area of gas phase chemistry and physics, which are at the cutting edge of research.

Buch. Condizione: Neu. Neuware - Alkaloids: Chemical and Biological Perspectives, the 15th volume of the ACBP series, features four important reviews of research on alkaloids. Chapter 1 is the first comprehensive review of the carbon-13 and proton NMR shift assignments and physical constants of diterpene alkaloids and their derivatives. In addition to the catalogue of spectral and physical data, the chapter includes a table of the occurrences of these alkaloids in various plant species, tables containing molecular formulas versus calculated high-resolution mass values, and calculated high-resolution mass values versus the molecular formulas of diterpenoid alkaloids, as well as seven tables summarizing the carbon-13 chemical shifts of various functional groups in diterpenoid alkaloids.

Buch. Condizione: Neu. Neuware - Features the Beginnings of Chromatography, which highlights MS Tswett, the inventor of chromatography, and several other early pioneers. This title includes a bibliography of publications on the history of the evolution of chromatography. It also contains chapters on support and stationary phases, and separations.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Machine component wear is one of the costliest problems within industry. In fact, a 1997 survey in the UK placed wear costs at 25% of turnover, or approximately $1 billion. In many cases, making design and or material changes can reduce this cost by 50% or more! This handbook reviews component wear, and guides the reader through solutions to wear problems, testing methods for materials and wear mechanisms, and information on wear performance of different materials for components. The bottom line is that it helps to reduce ''the bottom line'' removing risks associated with changes to machinery.This book is based on practical use. It outlines the following practices: reviews of wear mechanisms that occur in various types of machinery and solutions to industrial wear problems; guides to relative wear performance of different component materials; comparison of the wear performance of those materials; reviews of laboratory tests to simulate wear, and selection of appropriate tests; identification of improved materials, and; examination of worn surfaces. 157 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Geometric Topology is a foundational component of modern mathematics, involving the study of spacial properties and invariants of familiar objects such as manifolds and complexes. This volume, which is intended both as an introduction to the subject and as a wide ranging resouce for those already grounded in it, consists of 21 expository surveys written by leading experts and covering active areas of current research. They provide the reader with an up-to-date overview of this flourishing branch of mathematics. 1144 pp. Englisch.
