Nutrition and Feeding of Fish, Second Edition (Aquaculture)

Book Description

Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture.
This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented.
Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

A Gr8 Book on DFT Concepts.......2007-07-05

I like this book and would recommend it to any beginner into density functional theory. It explains all the modern electronic structure techniques in a rather simple language. Its much more easier and quicker than going into hundreds of papers and not knowing where to start.

The biggest issue with this book is a rather poor organisational structure to the book. That's why I've given it a 4/5 rating. There are some concepts that have been easily thrown in at the end, into the appendices.. and having to turn pages too frequently can be annoying.

But the good work has been done & I'd ask Mr Martin to re-organise the content.

This book has the potential to be a classic.

Excellent book.......2006-03-21

As a graduate student attempting to learn density functional theory and its use in computer programmes, I have found this book to be an excellent addition to my library. Well structured and written.

Not impressive.......2005-06-30

Although the topics the book embrasses are current and essential for practising chemists, physisists and materials scientists the pedagogic care with which it explains some of the topics is poor.

The author makes the assumption that the reader is familiarized with the heavy mathematical formalism and notation which is commonplace in specialized physics articles but fails to remember that graduate students that don't have a physics background, and come from other schools of thought such as chemistry, biochemistry or materials science, might be target readers.

For instance the book's introduction to Hartree-Fock theory must be the most complicated I've ever seen with constant recourse to Dirac's delta function (without even revealing its presence, stating simply that it should be there). The link between DFT and statistical thermodynamics although interesting is not essential for the heart of the discussion. Some classic program applications like Siesta are presented but you get the feeling that it's just for show off.

All in all if you're a physicist with some years of experience in the field of planewave computation you might find the book interesting.

Otherwise if you're a beginner like me forget it! The book by Efthimios Kaxiras (Atomic and Electronic Structure of Solids) is more revealing and pedagogic and supplies every detail in the mathematical formalism. Some physicists with a more chemical sensitivity such as Harrison, chemists such as Roald Hoffmann, Jeremy Burdett or Michael Springborg or materials scientists like Adrian Sutton or David Pettifor are better suited for the novice.

Outstanding.......2004-07-07

This book was recommended to me to help me in my research, and has turned out to be one of the best recommendations I have ever received. This is a great book; by far the best I have come across on the topic of computing the properties of condensed phase materials by quantum mechanical simulations. Here are the reasons why.

1. The chapters are well laid out and one chapter flows neatly to the next.

2. The math is kept to a minimum; the author makes a point of communicating important principles and ideas in concise sentences without resorting to derivations. This is ideal for engineers like me; who by training do not know that much math as compared to physicists who specialize in the solid state.

3. Important ideas are clarified up front. Many texts will lead the reader through long and windy paths of proofs and logic before arriving at the conclusion; thereby losing their reader in the process. Not here; important points are stated clearly at the beginning and at the end of each section.

4. Compare, contrast, and context. There are many ideas, models, approximations, and theorems that have been developed in the past century related to electronic structure. Many of these are closely related to each other in their inspiration, derivation, practice, and/or applications. This book makes the connections between the different concepts. For a non-expert reading through the electronic structure literature, terms like APW, OPW, PAW, LAPW, LMTO, etc... can be quite confusing if not placed within an overriding context. This book provides that context.

5. Good use of appendices. Electronic structure is a lot like politics; most practicioners in either field did not receive formal educations in the subject, but instead got into it under the apprenticeship of other people. This is reflected by a lot of literature by those who succeeded in the field; most of it good in showing of the authors' achievements, but generally useless in preparing the next generation of practicioners. For electronic structure, this is manifested by the many books that require prior knowledge of quantum, thermo, crystallography, mat sci, etc.. In effect, these books were written by experts to be read by other experts. Not this book. Basic ideas are kept in the text; and specific proofs and derivations are kept in the appendices. The result is a text that is much easier to read than most others.

6. The book is concept driven; not application driven. Most texts in materials simulations are actually a compilation of chapters written independently by multiple authors. Each chapter might be given a general title; but the text will be bias towards the research of its authors. For example, a chapter on surface calculations might focus entirely on adsorption, or relaxation/reconstruction, or optical properties; but surely not touching all these subjects. This book does not do this; each chapter is driven by basic concepts, and one concept leads to the next.

Book Description

A comprehensive, practical examination of the basic principles and inner mechanics of matter . . .

Moving from pure principles to real applications, the Quantum Chemistry Workbook is a step-by-step study guide to the inner workings of nature's fundamental systems: free atoms, small molecules, polymers, and crystals. Beginning with a short, clear summary of the basics of quantum mechanics, the Workbook offers a chapter-by-chapter exposition in a highly interactive exercise and question format that allows readers to work through the main concepts discussed. Not simply a conventional workbook, the Quantum Chemistry Workbook encourages discovery and original reflection, allowing users, through its rigorous give and take, to discover the intriguing connections hidden within the science. The Workbook includes:

A comparative overview of how basic concepts and principles actually work in free atoms, small molecules, polymers, and crystals
A practical look at the approximation level of a one-electron type
A complete examination of momentum space, with numerous conceptual illustrations
Atomic units used throughout

Book Description

This textbook does away with the classic, unimaginative approach and comes straight to the point with a bare minimum of mathematics—emphasizing the understanding of concepts rather than presenting endless strings of formulae. It nonetheless covers all important aspects of computational chemistry, such as

vector space theory
quantum mechanics
approximation methods
theoretical models
and computational methods

Throughout the chapters, mathematics are differentiated by necessity for understanding - fundamental formulae, and all the others. All formulae are explained step by step without omission, but the non-vital ones are marked and can be skipped by those who do not relish complex mathematics.

The reader will find the text a lucid and innovative introduction to theoretical and computational chemistry, with food for thought given at the end of each chapter in the shape of several questions that help develop understanding of the concepts.

What the reader will not find in this book are condescending sentences such as, 'From (formula A) and (formula M) it is obvious that (formula Z).'

Too many fundamental errors to be worth considering........2007-06-22

While the stated goal of a treatment of theoretical and computational chemistry without irrelevant mathematical details is admirable, this book falls far short of its ambitious goals.

The thinness of the book, rather than evidence of concise exposition, leaves much to be desired in its selection of what mathematical details are omitted and what is left in. It is far too simplistic to the point of misleading, Even many of the pictures, while certainly colorful, are often banal and unproductive (Figure 4.1 is a prime example of a complete waste of ink).

The book is unfortunately also rife with glaring mistakes. One particular egregious example is the use of the term 'molecular dynamics' wherever 'molecular mechanics' is meant, resulting in incorrect conflation of these concepts. Poor notation which fails to distinguish between states as kets vs. their position-space representations gets the authors into trouble, especially when writing expressions involving gradients, or worse, using kets in their exposition of molecular mechanics! Another fundamental error is the explicit use of a time operator when discussing energy-time uncertainty, which is wrong since energy-time uncertainty does *not* follow from the usual operator commutator relationships such as the one used to demonstrate position-momentum uncertainty (as explained in A. Peres's book and many others).

In conclusion, save your money and get another book. It is too full of errors, frivolous details and misleading 'derivations' to be worth serious attention.

ASIN: 0471553654

Book Description

Quantum Mechanics for Chemists is designed to provide chemistry undergraduates with a basic understanding of the principles of quantum mechanics. The text assumes some knowledge of chemical bonding and a familiarity with the qualitative aspects of molecular orbitals in molecules such as butadine and benzene. Thus it is intended to follow a basic course in organic and/or inorganic chemistry.

Book Description

The theory of surface states underlies our knowledge of the behaviour of electrons at solid surfaces, which is of paramount importance in understanding the mechanisms by which solid-state devices operate and catalytic reactions proceed. In this work, although the subject is viewed through the
"theoretical eye" of a physicist, the topics are treated in an elementary fashion, so the book should appeal to both theoretical and experimental surface scientists from chemistry, materials science and electronic engineering. The main features of the presentation are its instructive, model-based
approach; detailed step-by-step derivations of a the equations; smooth progression through the simple wave-function matching techniques to the more sophisticated Green-function methods; and the historical theme, which traces the evolution of the subject from its founding by the Nobel Laureate Igor
Tamm in 1932, through the invention of the transistor in 1947 by Schockley, Bardeen and Brattain, to recent developments.
