Download or read book Ph Measurements written by C Westcott and published by Elsevier. This book was released on 2012-12-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: pH Measurements is a seven-chapter simplified text on obtaining a high degree of accuracy in practical pH measurement. The introductory chapter of this book relates the principles of pH measurements to the actual measurement. This chapter specifically tackles the factors involved in the measurement and what magnitude of effect does each factor have on the measurement. These topics are followed by discussions on the components of pH equipment and technique, including the electrodes and buffers. A chapter considers the general approach of pH measurements and illustrates with examples of some common difficult samples. The concluding chapter shows the isolation and correction a pH equipment malfunction. pH equipment operators and users will find this book rewarding.
Download or read book Determination of PH written by Roger Gordon Bates and published by . This book was released on 1964 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: In portraying the rise and fall, in eighteenth century Ireland and England, of Barry Lyndon - an adventurer-gambler, a cad and a romantic idealist - Kubrick departs from Thackeray's picaresque novel in scope and tone. The first person narrator of the novel gives way in the film to the third person who assumes a good deal of the storytelling function, adding to the sense of detachment and abstraction typical of Kubrick. The way that this film polarised the critics suggests that it may hold a key to his oeuvre. Enervating pictorialism or a stately meditation upon the trappings of cultural ritual that we call civilisation? The painterly tableaux suggest the 'otherness' of a past era - a world as alien as that of 2001 - in a way matched by few other period films.

"pH and Brain Function is an important resource for researchers in all areas of neuroscience as well as cell biology and physiology." --Book Jacket.
Download or read book Biology of the Insect Midgut written by M. Lehane and published by Springer Science & Business Media. This book was released on 1996-10-31 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entomological research benefits from a great diversity of technical approaches - from the molecular to the descriptive - and these are applied to an even greater diversity of insect species. As a consequence, common themes and trends in entomological research can often be overlooked as each researcher focuses on his or her own area of interest. The purpose of this volume is to bring together diverse areas of research under one common theme. The book is divisible into four conceptual areas: the structural biology of the midgut; digestion and transport; the insect midgut as a target for control strategies; and the idgut as an environment for other organisms. Each chapter is written by scientists active in the reviewed research area and a truly international team of contributors has been chosen by the editors. Biology of the Insect Midgut will be of immense use to advanced undergraduate and postgraduate students, and researchers in entomology, physiology and pest control.

Download or read book Methods of Seawater Analysis written by Klaus Grasshoff and published by John Wiley & Sons. This book was released on 2009-07-30 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.
Download or read book Buffers for pH and Metal Ion Control written by D. Perrin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a practical manual for chemists, biologists and others whose work requires the use of pH or metal-ion buffers. Much information on buffers is scattered throughout the literature and it has been our endeavour to select data and instructions likely to be helpful in the choice of suitable buffer substances and for the preparation of appropriate solutions. For details of pH measurement and the preparation of standard acid and alkali solutions the reader is referred to a companion volume, A. Albert and E. P. Serjeant's The Determination of Ionization Constants (1971). Although the aims of the book are essentially practical, it also deals in some detail with those theoretical aspects considered most helpful to an understanding of buffer applications. We have cast our net widely to include pH buffers for particular purposes and for measurements in non-aqueous and mixed solvent systems. In recent years there has been a significant expansion in the range of available buffers, particularly for biological studies, largely in conse quence of the development of many zwiUerionic buffers by Good et al. (1966). These are described in Chapter 3.
Download or read book Grit written by Angela Duckworth and published by Simon and Schuster. This book was released on 2016-05-03 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this instant New York Times bestseller, Angela Duckworth shows anyone striving to succeed that the secret to outstanding achievement is not talent, but a special blend of passion and persistence she calls “grit.” “Inspiration for non-geniuses everywhere” (People). The daughter of a scientist who frequently noted her lack of “genius,” Angela Duckworth is now a celebrated researcher and professor. It was her early eye-opening stints in teaching, business consulting, and neuroscience that led to her hypothesis about what really drives success: not genius, but a unique combination of passion and long-term perseverance. In Grit, she takes us into the field to visit cadets struggling through their first days at West Point, teachers working in some of the toughest schools, and young finalists in the National Spelling Bee. She also mines fascinating insights from history and shows what can be gleaned from modern experiments in peak performance. Finally, she shares what she’s learned from interviewing dozens of high achievers—from JP Morgan CEO Jamie Dimon to New Yorker cartoon editor Bob Mankoff to Seattle Seahawks Coach Pete Carroll. “Duckworth’s ideas about the cultivation of tenacity have clearly changed some lives for the better” (The New York Times Book Review). Among Grit’s most valuable insights: any effort you make ultimately counts twice toward your goal; grit can be learned, regardless of IQ or circumstances; when it comes to child-rearing, neither a warm embrace nor high standards will work by themselves; how to trigger lifelong interest; the magic of the Hard Thing Rule; and so much more. Winningly personal, insightful, and even life-changing, Grit is a book about what goes through your head when you fall down, and how that—not talent or luck—makes all the difference. This is “a fascinating tour of the psychological research on success” (The Wall Street Journal).
