While the organometallic chemistry of the d-block transition elements has been a flourishing field for the past 25 years, it has only been in the last several years that dramatic activity and progJ'ess has occurred in the area of lanthanide and actinide organometallic chemistry. The f. -element organometallic research effort has been truly multinational and multidisciplinary. In a large number of countries, sCientists have become increasingly interested in the synthesis, reactivity, spectroscopy, and the molecular and electronic structures of f-element organometallic compounds. The backgrounds of these scientists range from organic, inorganic, nuclear, and catalytic chemistry to chemical and nuclear physics. The motivations for the study of f-element organometallics have been equally varied. In the area of basic research, there has been a growing realization that the lanthanides and actinides represent two unique and, to a great extent, neglected families of elements in which many fascinating aspects of chemistry and bonding remain to be explored. On a more practical level, an increasing number of these elements play important roles in nuclear energy production and in industrial catalytic processes. It has become apparent that efficiency and safety in both areas could greatly benefit from increased knowledge. In the past there has been no suitable international forum available for bringing together researchers in the diverse areas of f-element organometallic science mentioned above.

The first f-block elements were discovered in the 18th and 19th centuries, since the advent of the cyclotron many more of them have been isolated. The applications of these elements range from smoke detectors to catalytic converters and they are used widely in industry, for example, in the refining of oil and the manufacture of glass and ceramics.

The lanthanides and actinides (the f elements) are rarely studied in detail by chemistry undergraduates. More often they appear as an afterthought in bonding, spectroscopy, magnetism, coordination chemistry, and organometallics courses. This is largely because of a lack of an accessible text treating the chemistry of these elements in one cover. Moreover, the placement of lanthanides and actinides in the closing pages of standard inorganic chemistry text books serves to marginalise these elements further. The f elements has therefore been written to fill a gap in the undergraduate chemistry textbook market. It covers much of the fundamental chemistry of the lanthanide and actinide elements, including coordination chemistry, solid state compounds, organometallic chemistry, electronic spectroscopy, and magnetism. Many comparisons are made between the chemistry of the lanthanides and actinides and that of the transition elements, which is generally much more familiar to undergraduate chemistry students. The book uses the chemistry of the f elements as a vehicle for the communication of several important chemical concepts that are not usually discussed in detail in undergraduate courses, for example the chemical consequences of relativity and the lanthanide and actinide contractions. Many important modern applications of f element chemistry, e.g. the use of actinides in nuclear power generation and of the lanthanides in magnetic resonance imaging and catalytic converters in motor vehicle exhausts, are also discussed in depth.

This breakthrough study argues for a significant link between phonetics and phonology. Its authors propose that phonological rules and representations are tightly constrained by the interaction of formal conditions drawn from a limited universal pool and substantive conditions of a phonetically motivated nature. They support this proposal through principled accounts of a variety of topics such as vowel harmony, neutrality, and under specification.Unlike much work on this topic, Archangeli and Pulleyblank provide an explicit account of their assumptions, defined in a comprehensive theory of phonological rules and representations. The authors survey an impressive range of data, including an investigation of cross-linguistic patterns of ATR Harmony. They demonstrate that their theory is flexible enough to account for variation in individual phonological systems, yet it is firmly constrained by a small set of well-motivated principles. Extensive references throughout the book to published and unpublished work provide a valuable roadmap through this semicharted terrain.The approach in Grounded Phonology is modular, in that it presents a theory composed of subtheories, each of which is independently motivated, and the role of each module is to constrain the range of possibilities (of wellformedness)in its domain. Differences among languages can arise from differing intramodular selections or from interaction among modules.Diana Archangeli is Associate Professor in the Department of Linguistics at the University of Arizona.

The past decade has seen a dramatic acceleration of activity and interest in phenomena surrounding lanthanide and actinide organo metallic compounds. Around the world, active research in organo-f element synthesis, chemistry, catalysis, crystallography, and quantum chemistry is in progress. This activity has spanned a remarkably wide range of disciplines, from synthetic/mechanistic inorganic and organic chemistry to radiochemistry, catalytic chemistry, spectroscopy (vibra tional, optical, magnetic resonance, photoelectron, Mossbauer), X-ray and neutron diffraction structural analysis, as well as to crystal field and molecular orbital theoretical studies at the interface of chemistry and physics. These investigations have been motivated both by fundamental and applied goals. The evidence that f-element organo metallic compounds have unique chemical and physical properties which cannot be duplicated by organometallic compounds of d-block elements has suggested many new areas of endeavor and application. For these reasons, a great many scientists felt the need for some international forum devoted exclusively to the subject of lanthanide and actinide organometallic compounds. In September of 1978, a NATO Advanced Study Institute entitled, "Organometallics of the f-Elements," was held at the SOGESTA Conference Center near Urbino, Italy. It was the universal feeling of the partic ipants that this first meeting was a great success and that vital international communication and collaboration had been stimulated. The principal lectures at this Institute were published by Reidel in 1979 as part of the NATO ASI Monograph Series ("Organometallics of the f-Elements," T. J. Marks and R. D. Fischer, editors).

The f-elements and their compounds often possess an unusually complex electronic structure, governed by the high number of electronic states arising from open f-shells as well as large relativistic and electron correlation effects. A correct theoretical description of these elements poses the highest challenges to theory. Computational Methods in Lanthanide and Actinide Chemistry summarizes state-of-the-art electronic structure methods applicable for quantum chemical calculations of lanthanide and actinide systems and presents a broad overview of their most recent applications to atoms, molecules and solids. The book contains sixteen chapters, written by leading experts in method development as well as in theoretical investigations of f-element systems. Topics covered include: Relativistic configuration interaction calculations for lanthanide and actinide anions Study of actinides by relativistic coupled cluster methods Relativistic all-electron approaches to the study of f- element chemistry Relativistic pseudopotentials and their applications Gaussian basis sets for lanthanide and actinide elements Applied computational actinide chemistry This book will serve as a comprehensive reference work for quantum chemists and computational chemists, both those already working in, and those planning to enter the field of quantum chemistry for f-elements. Experimentalists will also find important information concerning the capabilities of modern quantum chemical methods to assist in the interpretation or even to predict the outcome of their experiments.

The F programming language is a dramatic new development in scientific programming. Building on the well-established strengths of the Fortran family of languages, it is carefully crafted to be both safe and regular, whilst retaining the enormously powerful numerical capabilities of its parent language, Fortran 90, as well as its data abstraction capability. Thus, an array language becomes available as part of a medium-size, widely-available language for the first time. In this respect,the language is clearly superior to older ones such as Pascal, C, and Basic. The book begins with an introductory chapter, then describes, in turn, the features of the language: language elements, expressions and assignments, control constructs, program units and procedures, array features, intrinsic procedures, and the input/output facilities. It is completed by six appendices, including the difference between F and Fortran 90, and solutions to most of the exercises. In the absence of a formal standard for F, this book is the defining document for the language, setting out the complete syntax and semantics of the language in a readable but thorough way. It is essential reading for users of F.

The truth about English is that it can get pretty boring. Dangling modifiers, gerunds, punctuation marks--it's enough to make you want to drop out of high school. Swearing and sex on the other hand, well, these time-honored pastimes warm the cockles of our hearts. Now, The Elements of F*cking Style drags English grammar out of the ivory tower and into the gutter, injecting a dull subject with a much-needed dose of color. This book addresses everything from common questions ("What the hell is a pronoun?") to philosophical conundrums ("Does not using paragraphs or periods make my thesis read like it was written by a mental patient?"). Other valuable sections include: •All I've got in this world are my sentences and my balls, and I don't break 'em for nobody •A colon is more than an organ that gets cancer •Words your bound to f*ck up One glance at your friend's blog should tell you everything you need to know about the sorry state of the English language. This book gives you the tools you need to stop looking like an idiot on message boards and in interoffice memos. Grammar has never before been so much f*cking fun.

Increased consumption of electronic equipment has brought with it a greater demand for rare earth elements and metals. Adding to this is the growth in low carbon technologies such as hybrid fuel vehicles. It is predicted that the global supply of rare earth elements could soon be exhausted. A sustainable approach to the use and recovery of rare earth elements is needed, and this book addresses the political, economic and research agendas concerning them. The problem is discussed thoroughly and a multi-disciplinary team of authors from the chemistry, engineering and biotechnology sectors presents a range of solutions, from traditional metallurgical methods to innovations in biotechnology. Case studies add value to the theory presented, and indirect targets for recovery, such as municipal waste and combustion ash are considered. This book will be essential reading for researchers in academia and industry tackling sustainable element recovery, as well as postgraduate students in chemistry, engineering and biotechnology. Environmental scientists and policy makers will also benefit from reading about potential benefits of recovery from waste streams.
