Much of this book was written during a sabbatical visit by J. C. H. S. to the Max Planck Institute in Stuttgart during 1991. We are therefore grateful to Professors M. Ruhle and A. Seeger for acting as hosts during this time, and to the Alexander von Humbolt Foundation for the Senior Scientist Award which made this visit possible. The Ph. D. work of one of us (J. M. Z. ) has also provided much of the background for the book, together with our recent papers with various collaborators. Of these, perhaps the most important stimulus to our work on convergent-beam electron diffraction resulted from a visit to the National Science Foundation's Electron Microscopy Facility at Arizona State University by Professor R. H(lJier in 1988, and from a return visit to Trondheim by J. C. H. S. in 1990. We are therefore particularly grateful to Professor H(lJier and his students and co-workers for their encouragement and collaboration. At ASU, we owe a particular debt of gratitude to Professor M. O'Keeffe for his encouragement. The depth of his under standing of crystal structures and his role as passionate skeptic have frequently been invaluable. Professor John Cowley has also been an invaluable sounding board for ideas, and was responsible for much of the experimental and theoretical work on coherent nanodiffraction. The sections on this topic derive mainly from collaborations by J. C. H. S. with him in the seventies."

R6,040 Discovery Miles 60 400 Ships in 10 - 15 working days

From its early days in the 1950s, the electron microanalyzer has offered two principal ways of obtaining x-ray spectra: wavelength dispersive spectrometry (WDS), which utilizes crystal diffraction, and energy dispersive spectrometry (EDS), in which the x-ray quantum energy is measured directly. In general, WDS offers much better peak separation for complex line spectra, whereas EDS gives a higher collection efficiency and is easier and cheaper to use. Both techniques have undergone major transformations since those early days, from the simple focusing spectrometerand gas proportional counter of the 1950s to the advanced semiconductor detectors and programmable spectrometersoftoday. Becauseofthesedevelopments, thecapabilities and relative merits of EDS and WDS techniques have been a recurring feature of microprobeconferences for nearly40 years, and this volume bringstogetherthepapers presented at the Chuck Fiori Memorial Symposium, held at the Microbeam Analysis Society Meeting of 1993. Several themes are apparent in this rich and authoritative collection of papers, which have both a historical and an up-to-the-minute dimension. Light element analysis has long been a goal of microprobe analysts since Ray Dolby first detected K radiation with a gas proportional counter in 1960. WDS techniques (using carbon lead stearate films) were not used for this purpose until four years later. Now synthetic multilayers provide the best dispersive elements for quantitative light element analy sis-still used in conjunction with a gas counter."

This volume features contributions from participants of an ESRF Workshop on "Systems Biology" held in Berkeley, USA, in November 2005. Significant progress has been made in developing technologies that enable systems interrogations at a molecular level. Overwhelming data sets are generated ever faster, providing enormous detail. In order to be useful, however, all these data must be appropriately integrated, analyzed in the context of all other information available and eventually modelled, enabling predictions for therapeutic interventions. Recent successes and challenges of applying systems level measurements to the different steps of drug discovery and development in the pharmaceutical industry are summarized.

R4,572 Discovery Miles 45 720 Ships in 12 - 17 working days

Emphasis in agricultural production has shifted from mere quantity to quality products. Practical experience and scientific investigations have shown that, of the various culture measures, balanced fertilization above all exerts a considerable influence on the quality of agricultural products. Simply adding more of what the crop has already absorbed to capacity is unproductive, expensive, wasteful and damaging to the environment. Therefore, balanced crop nutrition increases crop quality, safeguards natural resources and brings benefit to the farmer. Otherwise rapid population growth and severe urbanization will exhaust our natural resources.

Towards Holistic Medicine (Hardcover): Bing Yuan Towards Holistic Medicine (Hardcover)
Bing Yuan
R4,807 Discovery Miles 48 070 Ships in 12 - 17 working days

In recent years, systems biology seems to have encountered insurmountable obstacles. Precision medicine faces the problem of integration in disease regulation, despite the establishment of biomarker systems and the continuous discovery of new targeted drugs. Towards Holistic Medicine explores the development of modern medicine and the future medical model in the broader perspective of Chinese and Western medicine, biology, and even the methodological evolution of natural science in recent centuries. The book discusses how modern medicine will move past systems biology and precision medicine and toward holistic medicine.

Christopher Kaczor
R1,307 Discovery Miles 13 070 Ships in 9 - 15 working days

The overturning of Roe v Wade makes the ethical consideration of abortion more important than ever. Appealing to reason rather than religious belief, this book is the most comprehensive case against the choice of abortion yet published. This third edition of The Ethics of Abortion critically evaluates all the major grounds for denying basic rights to fetal human beings, including the views of those who defend not only abortion but also post-birth abortion. It also provides several (non-theological) justifications for the conclusion that all human beings, including those in utero, should be respected as persons. This book also critiques the view that abortion is not wrong even if the human fetus is a person. The Ethics of Abortion examines hard cases for those who are prolife, such as abortion in cases of rape or in order to save the woman's life, as well as hard cases for defenders of abortion, such as sex selection abortion and the rationale for being "personally opposed" but publicly supportive of abortion. It concludes with a discussion of whether artificial wombs might end the abortion debate. Answering the arguments of defenders of abortion, this book provides reasoned justification for the view that all intentional abortions are ethically wrong and that doctors and nurses who object to abortion should not be forced to act against their consciences. Updates and Revisions to the Third Edition Include: Discusses Achas Burin's 2014 essay, "Beyond Pragmatism: Defending the 'Bright Line' of Birth" in chapter 3 Incorporates into chapter 8 David Boonin's cogently argued 2019 book, Beyond Roe: Why Abortion Should be Legal - Even if the Fetus is a Person Expands chapter 9 to examine tragic cases in which prenatal diagnosis determines with certainty that a fetus will die shortly after birth Includes an updated and expanded section in chapter 11 on recent debates about conscience protections Considers in chapter 12 recent arguments that parents have a right to kill if the product of conception is in an artificial womb Updates statistics on numbers of abortions in the United States, including corrections to statistics that were once thought true but are now known as erroneous Updated bibliography

R5,953 Discovery Miles 59 530 Ships in 10 - 15 working days

I was pleased and at the same time filled with some misgivings when Professors Alberto Giotti end Ryan Huxtable asked me to introduce this book. The book is the outcome of the Symposium held in Firenze-San Miniato (PI), October 6-9, 1986. The symposium was entitled "Sulfur Amino Acids, Peptides and Related Compounds" and was the 7th international symposium on taurine ssnd assooiated substances. It is always difficult to introduce, with the right brevity end emphasis, a topic which has been studied in depth by numerous experte. Nevertheless, I shall do my best to give a historical perspeotive of the subjects of the meeting which I consider to be very important for the frontiers of researoh on taurine. ~he following topios have also beoome coherent areas of study during the development of researoh on taurine: metabolism, nutrition, neurochemistry, cardiovasoular regulation. Although taurine was isolated in 1821 by ~iedman and Gmel1n, its only biochemioal role known at the time was the synthesis of bile saIte in mammalian tissue. There has been an inoreasing interest in the biologioal action of taurine from metabolio aspects to other biologioal aspects (nutrition, development, eto.). In 1975 it was first demonstrated that taurine deprivation produoed retinal degeneration in cats; more reoent studies showed that a taurine-free diet or the administration of taurine transport inhibitors caused retinal degeneration in other mammlas. More reoent studies have pointed out the role of taurine in development, and the first part of this book is dedicated to these topios.

Jeff Jones
R4,630 Discovery Miles 46 300 Ships in 12 - 17 working days

This book addresses topics of mobile multi-agent systems, pattern formation, biological modelling, artificial life, unconventional computation, and robotics. The behaviour of a simple organism which is capable of remarkable biological and computational feats that seem to transcend its simple component parts is examined and modelled. In this book the following question is asked: How can something as simple as Physarum polycephalum - a giant amoeboid single-celled organism which does not possess any neural tissue, fixed skeleton or organised musculature - can approximate complex computational behaviour during its foraging, growth and adaptation of its amorphous body plan, and with such limited resources? To answer this question the same apparent limitations as faced by the organism are applied: using only simple components with local interactions. A synthesis approach is adopted and a mobile multi-agent system with very simple individual behaviours is employed. It is shown their interactions yield emergent behaviour showing complex self-organised pattern formation with material-like evolution. The presented model reproduces the biological behaviour of Physarum; the formation, growth and minimisation of transport networks. In its conclusion the book moves beyond Physarum and provides results of scoping experiments approximating other complex systems using the multi-agent approach. The results of this book demonstrate the power and range of harnessing emergent phenomena arising in simple multi-agent systems for biological modelling, computation and soft-robotics applications. It methodically describes the necessary components and their interactions, showing how deceptively simple components can create powerful mechanisms, aided by abundant illustrations, supplementary recordings and interactive models. It will be of interest to those in biological sciences, physics, computer science and robotics who wish to understand how simple components can result in complex and useful behaviours and who wish explore the potential of guided pattern formation themselves.

R3,789 Discovery Miles 37 890 Ships in 10 - 15 working days

This book explains how to analyze independent data from factorial designs without having to make restrictive assumptions, such as normality of the data, or equal variances. The general approach also allows for ordinal and even dichotomous data. The underlying effect size is the nonparametric relative effect, which has a simple and intuitive probability interpretation. The data analysis is presented as comprehensively as possible, including appropriate descriptive statistics which follow a nonparametric paradigm, as well as corresponding inferential methods using hypothesis tests and confidence intervals based on pseudo-ranks. Offering clear explanations, an overview of the modern rank- and pseudo-rank-based inference methodology and numerous illustrations with real data examples, as well as the necessary R/SAS code to run the statistical analyses, this book is a valuable resource for statisticians and practitioners alike.
