Aqueous Acid-base Equilibria and Titrations

Author: Robert De Levie

Publisher: Oxford University Press on Demand

ISBN: 9780198506171

Category: Science

Page: 91

View: 3813

This book will give students a thorough grounding in pH and associated equilibria, material absolutely fundamental to the understanding of many aspects of chemistry. It is, in addition, a fresh and modern approach to a topic all too often taught in an out-moded way. This book uses new theoretical developments which have led to more generalized approaches to equilibrium problems; these approaches are often simpler than the approximations which they replace. Acid-base problems are readily addressed in terms of the proton condition, a convenient amalgam of the mass and charge constraints of the chemical system considered. The graphical approach of Bjerrum, Hagg, and Sillen is used to illustrate the orders of magnitude of the concentrations of the various species involved in chemical equilibria. Based on these concentrations, the proton condition can usually be simplified, often leading directly to the value of the pH. In the description of acid-base titrations a general master equation is developed. It provides a continuous and complete description of the entire titration curve, which can then be used for computer-based comparison with experimental data. Graphical estimates of the steepness of titration curves are also developed, from which the practicality of a given titration can be anticipated. Activity effects are described in detail, including their effect on titration curves. The discussion emphasizes the distinction between equilibrium constants and electrometric pH measurements, which are subject to activity corrections, and balance equations and spectroscopic pH measurements, which are not. Finally, an entire chapter is devoted to what the pH meter measures, and to the experimental and theoretical uncertainties involved.

MEG-EEG Primer

Author: Riitta Hari,Aina Puce

Publisher: Oxford University Press

ISBN: 0190497777

Category: Medical

Page: 352

View: 2483

Magnetoencephalography (MEG) and electroencephalography (EEG) provide complementary views to the neurodynamics of healthy and diseased human brains. Both methods are totally noninvasive and can track with millisecond temporal resolution spontaneous brain activity, evoked responses to various sensory stimuli, as well as signals associated with the performance of motor, cognitive and affective tasks. MEG records the magnetic fields, and EEG the potentials associated with the same neuronal currents, which however are differentially weighted due to the physical and physiological differences between the methods. MEG is rather selective to activity in the walls of cortical folds, whereas EEG senses currents from the cortex (and brain) more widely, making it harder to pinpoint the locations of the source currents in the brain. Another important difference between the methods is that skull and scalp dampen and smear EEG signals, but do not affect MEG. Hence, to fully understand brain function, information from MEG and EEG should be combined. Additionally, the excellent neurodynamical information these two methods provide can be merged with data from other brain-imaging methods, especially functional magnetic resonance imaging where spatial resolution is a major strength. MEG-EEG Primer is the first-ever volume to introduce and discuss MEG and EEG in a balanced manner side-by-side, starting from their physical and physiological bases and then advancing to methods of data acquisition, analysis, visualization, and interpretation. The authors pay special attention to careful experimentation, guiding readers to differentiate brain signals from various artifacts and to assure that the collected data are reliable. The book weighs the strengths and weaknesses of MEG and EEG relative to one another and to other methods used in systems, cognitive, and social neuroscience. The authors also discuss the role of MEG and EEG in the assessment of brain function in various clinical disorders. The book aims to bring members of multidisciplinary research teams onto equal footing so that they can contribute to different aspects of MEG and EEG research and to be able to participate in future developments in the field.

This user friendly introduction highlights the importance of electrochemistry and its applications to the modern world and the future. In contrast to other texts currently available, it emphasises understanding and avoids using many pages of complex equations. It also describes the diverse applications of electrochemistry rather than focusing on analytical chemistry alone. Although the book follows a similar structure to the first edition, the earlier chapters have been extensively up-dated and the later chapters are entirely new. The text is supported by a large number of figures which illustrate key points. The book starts by describing the essential electrochemical techniques before moving on to cover experimental problems and applications. To reflect the present interest in fuel cells and the environment, these have become the focus of the final chapters. A useful appendix contains problems with fully worked answers to test the reader's understanding.

A Low-Cost Approach to PCR

Appropriate Transfer of Biomolecular Techniques

Author: Eva Harris,Nazreen Kadir

ISBN: 0195119266

Category: Medical

Page: 304

View: 7665

The polymerase chain reaction (PCR) is a technique used to replicate specific pieces of DNA millions of times, which permits the detection and analysis of minute amounts of nucleic acids. Since its introduction in the late 1980s, this technique has been applied not only in molecular biology research but also in fields as diverse as anthropology, phylogeny, and forensics. However, despite the large impact of PCR, many of its applications remain within the confines of research and the academic environment. Now, in A Low-Cost Approach to PCR: Appropriate Transfer of Biomolecular Techniques, Dr. Eva Harris makes this elegantly simple technique more accessible to researchers, physicians, and laboratory workers throughout the world. She provides a description of the theoretical basis of the technique, the practical details of the method, and the philosophy behind the technology transfer program that she developed over the last ten years. The book serves as a guide for potential users in developing countries and for scientists in developed countries who may wish to work abroad. In addition, the low-cost approach outlined in this book can be useful for high school, undergraduate, or continuing education programs in the United States. While the specific applications of PCR outlined in the book are immediately useful to the study of infectious diseases, the approach presented can be generalized to a number of other technologies and situations. The book will help laboratories in many areas of the world generate information on site for use by physicians, epidemiologists, public health workers, and health policy professionals to develop new strategies for disease control.
