Buch. Zustand: Neu. Neuware - Timothy Leary's advice to 'tune in, turn on and drop out' was a 1960s exhortation to experiment with LSD, but humans had been consuming ergot alkaloids related to lysergic acid diethylamide for at least a thousand years. Opium has been around even longer with its medicinal uses being known to the Ancient Sumerians as long ago as 3400 BC. This is the first book to cover all of the major psychoactive drugs (both natural and synthetic) in one volume, and the only one to cover all aspects of these drugs from their anthropological and sociological influences through to their chemistry and pharmacology. It covers a range of substances including LSD, opium, heroin, cocaine, cannabis, peyote, belladonna, mandrake, and absinthe. The book is highly readable and concentrates on the characters (e.g. authors, painters, pop stars, hippies, politicians and drug barons), both famous and infamous, who have ensured that psychoactive drugs hold an enduring fascination and interest for everyone. The basic chemistry and pharmacological activity covered together with a brief account of useful drugs that have emerged from a study of the psychoactive ones.

Taschenbuch. Zustand: Neu. Neuware - The application of statistics is central to the assessment of data quality and an understanding of statistics is essential for the interpretation of analytical results. 'Practical Statistics for the Analytical Scientist, A Bench Guide' was first published by the RSC in 1997. This well structured manual was designed to help practicing analytical scientists and students identify the correct statistical parameters and tests to apply to their data. Completely revised and updated, the second edition contains new sections on method validation, measurement uncertainty, effective experimental design and proficiency testing. Key features: -covers the essential statistics required in analytical science -describes the application of statistics in important quality assurance activities such as method validation, evaluating uncertainty and proficiency testing -aimed at analysts who may have little knowledge of statistics -focuses on applications rather than theory -'FAQs' in the introduction guide the reader to appropriate chapters -comprehensive list of symbols and notation -extensive worked examples illustrate key statistical techniques -self-assessment questions (with detailed solutions) to test understanding. The book the reader with a set of statistical tools to help them plan effective experiments and apply appropriate statistics for data evaluation.

Buch. Zustand: Neu. Neuware - This is a book of the proceedings of the Pan Africa Chemistry Network (PACN) Biodiversity Conference held at the University of Nairobi, Kenya, on 10-12 September 2008. One of the key activities of the RSC/Syngenta PACN is to connect African scientists through a cycle of conferences and workshops. This conference held at the University of Nairobi was the first of these. It brought together 150 delegates from 12 African countries - Botswana, Burundi, the Democratic Republic of Congo, Ethiopia, Kenya, Nigeria, Rwanda, South Africa, Sudan, Tanzania, Uganda and Zimbabwe - as well as from the UK and Brazil. The lectures covered topics such as making the best use of the diversity of Africa's plants in agriculture and medicine whilst benefiting communities in Africa; the chemistry and biological activity of natural products; agricultural practices for Africa; genetic diversity in farm animals and crop plants; analysis and the environment; understanding crop protection chemicals in the African context; water quality; conservation and the impact of tourism on biodiversity; biofuels; and the processing and use of waste materials. The resulting book, Aspects of African Biodiversity: Proceedings of the Pan Africa Chemistry Network Biodiversity Conference, Nairobi, 10-12 September 2008, provides a valuable overview of many aspects of biodiversity in Africa.

Buch. Zustand: Neu. Neuware - This is currently the only book available on the development of knowledge-based, and related, expert systems in chemistry and toxicology. Written by a pioneer in the field, it shows how computers can work with qualitative information where precise numerical methods are not satisfactory. An underlying theme is the current concern in society about the conflicts between basing decisions on reasoned judgements and wanting precise decisions and measurable effectiveness. As well as explaining how the computer programs work, the book provides insights into how personal and political factors influence scientific progress. The introduction of regulations such as REACH in Europe and modifications to UN and OECD Guidelines on assessment of chemical hazard mean that the use of toxicity prediction is at a turning point. They put a heavy burden on the chemical industry but, for the first time, allow for the use of computer prediction to support or replace in vivo and in vitro experiments. There is increasing recognition among scientists and regulators that qualitative computer methods have much to offer and that in some circumstances they may be more reliable and informative than quantitative methods. This excellent introduction to a field where employment opportunities are growing is aimed at students, scientists and academics with a knowledge of chemistry.

Buch. Zustand: Neu. Neuware - Major technology shifts do not happen overnight and rarely are they the result of a single breakthrough discovery. Nowhere is this more true than for the broad set of enabling technologies that we have come to simply call 'nanotechnology'. Rather than standing on the shoulders of a few intellectual giants, nanotechnologies are created by tens of thousands of researchers and scientists working on minute and sometimes arcane aspects of their fields of expertise in areas as diverse as medicine, telecommunications, solar cells, filtration, coatings, or ever smaller transistors for electronic devices. They come from different sciences, live in different parts of the world and work for different organizations (government laboratories, industry laboratories, universities, private research facilities). This book puts a spotlight on some of the scientists who are pushing the boundaries of technology and it gives examples of their work and how they are advancing knowledge one little step at a time. The book shatters the monolithic term 'nanotechnology' into the myriad of facets that it really is. It is a journey through the world of nanotechnology research and development, taking a personal look at how nanotechnologies get created today and by whom. The book covers 122 very specific research projects that are happening in laboratories around the world and provide commentaries from the scientists in their own words. The book is different to other books in this field because it provides a novel human touch to nanotechnology research by not only covering a wide range of research topics but also the (often nameless) scientists behind this research. The intention is to give the interested reader an idea of the many diverse aspects that today make up nanotechnology research and development. The book is a collection of Spotlight articles from the popular Nanowerk website and each article has been crafted with the author(s) of a scientific paper and signed off by them prior to being posted on Nanowerk. The book is intended for two broad groups of audiences - scientists and nanoscience students who want a bite-size, quick read to get a good first impression of what nanotechnologies are about and how they affect not only their own field but also neighbouring fields and other scientific disciplines further away. And a non-scientific readership that needs to (because it affects their organization and they have to acquaint themselves with nanotechnology) or wants to get a 'non-threatening' (i.e. no formulas, complex diagrams, or unexplained scientific terms) introduction, written by a non-scientist for non-scientists.

Buch. Zustand: Neu. Neuware - There have been enormous recent advances in our ability to produce and trap samples of translationally cold molecules (below 1 K) and ultracold molecules (below 1 mK). Molecules such as NH3, OH and NH have been cooled from room temperature to the milliKelvin regime by a variety of methods including buffer-gas cooling and Stark deceleration. Bose-Einstein condensates have been produced for dimers of both bosonic and fermionic alkali metal atoms, and the first signatures of ultracold triatomic and tetraatomic molecules have been observed. This book will include both cooling of molecules from high temperatures and formation of molecules in ultracold atomic gases; molecules in cold ionic gases and in helium droplets will also be covered.
