This book is about selectively toxic agents. That is to say, it is about those substances that affect certain cells without harming others, even when they are close neighbours. Toxicity need not be fatal. It can be made easily reversible, as is the case with general anaesthetics. Selective toxicity covers an immense field: most of the drugs used for treating illness in man and his economic animals, as well as all of the fungicides, insecticides, and weed killers that are used in agriculture. Essentially, this book is a discussion of the physical and chemical means which contribute to selectivity, and this is the basis of molecular pharmacology. _Selective Toxicity began as a course of lectures that Professor F. G. Young encouraged me to give in University College London, in 1948 and again in 1949. The first edition appeared in 1951, as a very small book because little was then known about the factors that provide selectivity. Since those early days, the subject has undergone tremendous development. At first, industry was un­ receptive to the word 'toxicity', however qualified! Yet the market was being supplied with biologically powerful substances of which several had the potential to cause harm. This aspect was brought to light by two events of the early 1960s. The first of these was the discovery that a sedative, thalidomide, administered to expectant mothers, after what was then considered to be adequate testing, had caused permanent deformities in about 10000 children.

Methanogenic archaea may have been among earth earliest organisms and today play essential roles in a variety of anaerobic habitants. The present investigation was to study the methanogen population in estuarine sediments in the mouth of Manimuthar River at the Palk Strait and seasonal sampling was made. Most Probable number (MPN) of methanogenic archaea was determined in the period of one year(2009). The archaeal populations were found to be at the maximum of 1.1x105 MPNgm-1 of wet sample during the post-monsoon season. The correlation co efficient (r) values calculated between the methanogenic archaea and various physico chemical parameters in this nitrogen, sodium shows a high significant correlation to the MPN viz., n=18; r=0.976; and r=0.977 at; p<0.001 level respectively. Seasonal variation in the methanogenic population could be influenced by independent abiotic variables such as temperature, salinity, pH, electrical conductivity, nutrients and minerals. The investigation concluded that the methanogenic populations were highly influenced by physico chemical parameters in estuarine ecosystem. This is the first report in distribution of methanogens in this region.

This textbook covers the fundamentals of physical chemistry, explaining the concepts in an accessible way and guiding the readers in a step-by-step manner. The contents are broadly divided into two sections: the classical physico-chemical topics (thermodynamics, kinetics, electrochemistry, transport, and catalysis), and the fabric of matter and its interactions with radiation. Particular care has been taken in the presentation of the algebraic parts of physico-chemical concepts, so that the readers can easily follow the explanations and re-work relevant discussion and derivations with pen and paper. The book is accompanied by a rich mathematical appendix. Each chapter includes a selection of (numerical) exercises and problems, so that students can practice and apply the learned topics. An appendix with solutions allows for controlling the learning success. Carefully prepared illustrative color images make this book a great support for teaching physical chemistry to undergraduate students.This textbook mainly addresses undergraduate students in life sciences, biochemistry or engineering, offering them a comprehensive and comprehensible introduction for their studies of physical chemistry. It will also appeal to undergraduate chemistry students as an accessible introduction for their physical chemistry studies.

Are living organisms―as Descartes argued―just machines? Or is the nature of life such that it can never be fully explained by mechanistic models? In this thought-provoking and controversial book, eminent geophysicist Walter M. Elsasser argues that the behavior of living organisms cannot be reduced to physico-chemical causality. Suggesting that molecular biology today is at the same point as Newtonian physics on the eve of the quantum revolution, Elsasser lays the foundation for a theoretical biology that points the way toward a natural philosophy of organic life.Explicitly repudiating "vitalism" (the notion that the laws of nature need to be modified when applied to living organisms), Elsasser argues instead that the structural complexity of even a single living cell is "transcomputational"―that is, beyond the power of any imaginable system to compute. Beginning from this insight, Elsasser leads the reader through a step-by-step process that ultimately arrives at the conclusion that living and non-living matter are separated by "a no-man's land of irrationality."Trained in Germany as a physicist, Elsasser first pondered the implications of quantum mechanics for biology as early as 1951. The more closely he studied the inherent complexity of life, the more skeptical he became of the reductionist view of organisms as tiny machines. "An organism," he concluded, "is a source of causal chains which cannot be traced beyond a terminal point because they are lost in the unfathomable complexity of the organism." Like the physicist who works within the bounds of an unfathomable universe, Elsasser argues, the biologist must seek answers within a system that is no less unfathomable.

This book covers the history, botany and agricultural aspects of the crop, summarising the techniques that have been developed to improve harvesting, processing and packaging of olives. Full details are provided relating to the physico-chemical and microbiological aspects of processing of each of the olive types. It will serve as a practical guide to agricultural scientists, food scientists and technologists who are involved in the preparation of table olives.

Within the discipline of environmental sciences, the stable-isotope methodology is being increasingly used, especially in the study of the water cycle and of paleo-climatology. This book reviews the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionalism, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. It focuses on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, concludes up the presentation.

An accessible yet rigorous introduction to the influential French philosopher Gilbert Simondon's philosophy of individuation.Gilbert Simondon (1924–1989), one of the most influential contemporary French philosophers, published only three works: L'individu et sa genèse physico-biologique (The individual and its physico-biological genesis, 1964) and L'individuation psychique et collective (Psychic and collective individuation, 1989), both drawn from his doctoral thesis, and Du mode d'existence des objets techniques (On the mode of existence of technical objects, 1958). It is this last work that brought Simondon into the public eye; as a consequence, he has been considered a “thinker of technics” and cited often in pedagogical reports on teaching technology. Yet Simondon was a philosopher whose ambitions lay in an in-depth renewal of ontology as a process of individuation―that is, how individuals come into being, persist, and transform. In this accessible yet rigorous introduction to Simondon's work, Muriel Combes helps to bridge the gap between Simondon's account of technics and his philosophy of individuation.Some thinkers have found inspiration in Simondon's philosophy of individuation, notably Gilles Deleuze and Félix Guattari. Combes's account, first published in French in 1999, is one of the only studies of Simondon to appear in English. Combes breaks new ground, exploring an ethics and politics adequate to Simondon's hypothesis of preindividual being, considering through the lens of transindividual philosophy what form a nonservile relation to technology might take today. Her book is essential reading for anyone who wants to understand Simondon's work.

Joseph Needham (1900 95) was a British biochemist and historian, known for his contributions to scientific research and writings on the history of science in China. First published in 1931, this book forms part of Needham's mammoth three-volume work on the subject of physico-chemical embryology. Broadly speaking, the volumes found their basis in three tasks: the collection from various scientific papers of the facts known about the physico-chemical basis of embryonic development; the relation of these facts to each other and to the facts derived from the labours of investigators in morphological embryology; and, on the basis of the first two tasks, ascertaining whether any generally valid principles were apparent. Illustrative figures and tables are included throughout. This book will be of value to anyone with an interest in the works of Needham and the development of chemical embryology."
