Download or read book Calculations for Molecular Biology and Biotechnology written by Frank H. Stephenson and published by Academic Press. This book was released on 2010-07-30 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculations for Molecular Biology and Biotechnology: A Guide to Mathematics in the Laboratory, Second Edition, provides an introduction to the myriad of laboratory calculations used in molecular biology and biotechnology. The book begins by discussing the use of scientific notation and metric prefixes, which require the use of exponents and an understanding of significant digits. It explains the mathematics involved in making solutions; the characteristics of cell growth; the multiplicity of infection; and the quantification of nucleic acids. It includes chapters that deal with the mathematics involved in the use of radioisotopes in nucleic acid research; the synthesis of oligonucleotides; the polymerase chain reaction (PCR) method; and the development of recombinant DNA technology. Protein quantification and the assessment of protein activity are also discussed, along with the centrifugation method and applications of PCR in forensics and paternity testing. - Topics range from basic scientific notations to complex subjects like nucleic acid chemistry and recombinant DNA technology - Each chapter includes a brief explanation of the concept and covers necessary definitions, theory and rationale for each type of calculation - Recent applications of the procedures and computations in clinical, academic, industrial and basic research laboratories are cited throughout the text New to this Edition: - Updated and increased coverage of real time PCR and the mathematics used to measure gene expression - More sample problems in every chapter for readers to practice concepts

Download or read book Quantum Theory of Finite Systems written by Jean-Paul Blaizot and published by Mit Press. This book was released on 1986 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and pedagogical account of the various methods used in the quantum theory of finite systems, including molecular, atomic, nuclear, and particle phenomena. Covering both background material and advanced topics and including nearly 200 problems, Quantum Theory of Finite Systems has been designed to serve primarily as a text and will also prove useful as a reference in research. The first of the book's four parts introduces the basic mathematical apparatus: second quantization, canonical transformations, Wick theorems and the resulting diagram expansions, and oscillator models. The second part presents mean field approximations and the recently developed path integral methods for the quantization of collective modes. Part three develops perturbation theory in terms of both time-dependent Feynman diagrams and time-independent Goldstone diagrams. A fourth part discusses variational methods based on correlated wavefunctions, including spin correlations. The approximation schemes are formulated for fermions and bosons at eigher zero or non-zero temperature. Although the formalism developed applies to both finite and infinite systems, the book stresses those aspects of the theory that are specific to the description of finite systems. Thus special attention is given to mean field approximations, the ensuing broken symmetries, and the associated collective motions such as rotations. Conversely, some specific features of systems with infinite numbers of degrees of freedom (such as the thermodynamic limit, critical phenomena, and the elimination of ultraviolet divergencies) are deliberately omitted. Jean-Paul Blaizot and Georges Ripka are associated with the Centre d'Etudes Nucleaires de Saclay.

Book excerpt: The Second International Conference on Nuclidic Masses was held in Vienna, Austria, July 15-19, 1963, using facilities of the International Atomic Energy Agency. This was the third conference in the general area of nuclidic masses in recent years. The first, a symposium held at the Max Planck Institut fur Chemie in 1956, was international in character but not in name. The First International Conference on Nuclidic Masses was held at McMaster University in September of 1960 in conjunction with and shortly after the meeting of the General Assembly of the International Union of Pure and Applied Physics and the Kingston Conference on Nuclear Structure. The Second International Conference on Nuclidic Masses was held under the sponsorship of the International Union of Pure and Applied Physics and the Nuclear Science Committee of the National Academy of Sciences-National Research Council of the United States. Financial support for the conference came from the United Nations Educational, Scientific, and Cultural Organization. The conference committee was made up of the following individuals: Chairman: J. H. E. MATTAUCH General Secretary: H. E. DUCKWORTH Local Secretary: F. P. VIEHBOCK w. W. BUECHNER B. GROSS E. R. COHEN M. J. HIGATSBERGER A. DE SHALIT A. O. C. NIER J. W. M. DuMoND H. H. STAUB B. S.

Download or read book The Translation Zone written by Emily Apter and published by Princeton University Press. This book was released on 2011-10-16 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Translation, before 9/11, was deemed primarily an instrument of international relations, business, education, and culture. Today it seems, more than ever, a matter of war and peace. In The Translation Zone, Emily Apter argues that the field of translation studies, habitually confined to a framework of linguistic fidelity to an original, is ripe for expansion as the basis for a new comparative literature. Organized around a series of propositions that range from the idea that nothing is translatable to the idea that everything is translatable, The Translation Zone examines the vital role of translation studies in the "invention" of comparative literature as a discipline. Apter emphasizes "language wars" (including the role of mistranslation in the art of war), linguistic incommensurability in translation studies, the tension between textual and cultural translation, the role of translation in shaping a global literary canon, the resistance to Anglophone dominance, and the impact of translation technologies on the very notion of how translation is defined. The book speaks to a range of disciplines and spans the globe. Ultimately, The Translation Zone maintains that a new comparative literature must take stock of the political impact of translation technologies on the definition of foreign or symbolic languages in the humanities, while recognizing the complexity of language politics in a world at once more monolingual and more multilingual.
