The Purpose of This Book

The presence of oxygen enhances the formation of the surface coating and depresses the flotation of pyrrhotite. It appears, therefore, that although the floatability of individual mineral may be controlled by pulp potential, the presence of several sulphide minerals, particularly when they are ground with steel media, leads to galvanic interaction among them and the alteration of certain mineral surfaces may be accelerated. Then the pulp potential dependence of their floatability may not follow those of individual mineral. 

This book systematically summarizes the researches on electrochemistry of sulphide flotation in our group. The various electrochemical measurements, especially electrochemical corrosive method, electrochemical equilibrium calculations, surface analysis and semiconductor energy band theory, practically, molecular orbital theory, have been used in our studies and introduced in this book. The collectorless and collector-induced flotation behavior of sulphide minerals and the mechanism in various flotation systems have been discussed. The electrochemical corrosive mechanism, mechano-electrochemical behavior and the molecular orbital approach of flotation of sulphide minerals will provide much new information to the researchers in this area. The example of electrochemical flotation separation of sulphide ores listed in this book will demonstrate the good future of flotation electrochemistry of sulphide minerals in industrial applications.

It is not the purpose of this book to discuss in detail the contributions of NMR spectroscopy to the determination of molecular structure. This is a specialized field in itself and a great deal has been written on the subject. In this section we shall consider only the application of NMR to the elucidation of stereoregularity in polymers. Numerous other applications of this powerful technique have also been made in polymer chemistry, including the study of positional and geometrical isomerism (Sec. 1.6), copolymers (Sec. 7.7), and helix-coil transitions (Sec. 1.11). We shall also make no attempt to compare the NMR spectra of various different polymers instead, we shall examine only the NMR spectra of different poly (methyl methacrylate) preparations to illustrate the capabilities of the method, using the first system that was investigated by this technique as the example. 

The purpose of this book is to share the experience of the author with those in the field. It is an attempt to make these subjects simple and interesting. The book should provide an easy approach to answer the problems an engineer or engineering student may face when handling these machines. 

The purpose of this book is to assist the user in controlling the hazards associated with the generation, accumulation, and discharge of static electricity by presenting... 

The purpose of this book is not to advance the bastions of academia, but to offer the tried and true design approaches implemented by many engineers in the power held. It offers advice and examples which can be immediately applied to the reader s own designs. 

The title of the book requires that a definition of plastics materials be given. This is however very difficult. For the purpose of this book I eventually used as a working definition Those materials which are considered to be plastics materials by common acceptance . Not a positive definition but one which is probably less capable of being criticised than any other definition I have seen. Perhaps a rather more useful definition but one which requires clarification is... 

Eor the purposes of this book, when we refer to safety eulture we are referring to the big pieture of how employees perform work as it relates to safety and health. Safety eulture, simply stated, is a belief and a way of handling safety-related situations that is engrained in all... 

For the purposes of this book, an alkaloid is regarded as a relatively complex, organic base, occurring naturally in a plant and usually possessing marked pharmacological activity. This excludes simple, naturally Occurring bases and the biological amines, which are adequately dealt with... 

It is the purpose of this book to afford a critical review covering both theoretical and experimental aspects of some of the most important and... 

An alternative avenue for the exploration of the polarity of a solvent is by investigation of its effect on a chemical reaction. Since the purpose of this book is to review the potential application of ionic liquids in synthesis, this could be the most productive way of discussing ionic liquid polarity. Again, the field is in its infancy, but some interesting results are beginning to appear. 

This book is intended to work like a short course. The material is presented in a progressive sequence, and the tone is informal. You may notice that the discussions are paced more slowly than usual for a book of this kind. There is also a certain amount of repetition. No apologies are offered for this—it is deliberate. Remember, the purpose of this book is to get you past the "entry barrier" and "up-to-speed" on the basics. This book is not intended to teach you everything you wanted to know about. An extensive bibliography, organized by topic, has been provided to help you explore material beyond the scope of this book. Selected topics are also treated in more detail in the Appendices. 

To fill this need is the purpose of this book, which should be useful to students, scientists, and engineers, as well as production and marketing managers and suppliers of materials, equipment and services. 

Since the purpose of this book is to describe applications of biodegradable polymers to drug delivery systems, particularly from the perspective of the materials employed, the approach taken in this chapter has been to focus on the natural biodegradable polymers which have been used most extensively as matrices for the delivery of drugs. Consideration was also given to the fact that collagen has not been the subject of any recent reviews. 

Examples of the lipase-catalyzed resolution of primary alcohols are listed in Fig. 17,63-126 TTigy usually give low enantioselectivity because of mechanistic reasons, and no effective method for improving the enantioselectivity is available. One of the purposes of this book is to create new ideas and possibilities in this field. The low-temperature method is a promising one to improve the enantioselectivity of these alcohols. 

In seeking a classification that does not present the disadvantages mentioned above, this classification cannot be replaced by those fixed by regulation. Texts on regulations have the disadvantage of presenting an important viscosity . The purpose of this book is not to suggest counter-proposals but to look for approaches that answer technical and scientific concerns. This will be returned to several times. 

This book, which incorporates materials written by some of the finest minds in pharmacy practice and education, can enable the reader to play a crucial role in improving the drug use process for patients, providers, payers, and society. The purpose of this book is to help hone your skills so you can make a real improvement in the therapies you provide to your patients. Current and future clinicians can rely on the information laid out here to enhance your knowledge and allow you to assist your patients with the sound advice that they expect you to provide. Use the text, case histories, and numerous examples detailed here to expand your therapeutic skills, and to help positively impact your patients in the years to come. 

An accident can be defined as "an unplanned event or sequence of events that results in an undesirable consequence." For the purposes of this book, undesirable consequence is defined as an explosion or fire. 

Proteomics is an interdisciplinary science that includes biology, bioinformatics, and protein chemistry. The purpose of this book is to provide the reader with an overview of the types of questions being addressed in proteomics studies and the technologies used to address those questions. The first chapter is a concise outline of the field as it presently stands. The second chapter provides an overview of the use of 2D-gel electrophoresis and mass spectrometry to identify proteins, as well as post-translational...
