Free Download An Introduction to Gauge Theories, 2nd Edition English | 2025 | ISBN: 1032883227 | 290 pages | True PDF,EPUB | 13.56 MB Written by world-leading experts in particle physics, this new book from Luciano Maiani and Omar Benhar, with contributions from the late Nicola Cabibbo, is based on Feynman's path integral formulation of quantum field theory. Key elements of gauge theories are described―Feynman diagrams, gauge-fixing, Faddeev-Popov ghosts―as well as renormalisation in Quantum Electrodynamics. Quarks and QCD interactions are introduced. Renormalisation group and high-momentum behaviour of the coupling constants are discussed in both QED and QCD, with asymptotic freedom derived at one-loop. These concepts are related to the Higgs boson mass and models of grand unification. The new edition has been updated throughout, with two new chapters presenting an outline of Lattice QCD field theory and the renormalisation group analysis of the prominent ΔI = 1/2 rule in kaon decay. The most recent Lattice QCD results on the light quark mass spectrum and on a quantitative justification of the ΔI = 1/2 rule are also discussed. The Chapter on the anomalous magnetic moment of the muon now includes an update on the Lattice QCD determination of the hadronic vacuum polarisation contribution, which turns out to be in good agreement with the most recent experimental determination of the muon g-2.  Free Download An Introduction to Environmental Biotechnology By Milton Wainwright 1999 | 171 Pages | ISBN: 1461373948 | PDF | 15 MB An Introduction to Environmental Biotechnology provides an introduction to the subject of environmental biotechnology. Environmental biotechnology refers to the use of micro-organisms and other living systems to solve current environmental problems such as the detoxification of pollutants and clean-up of oil tanker spills. Additionally, it refers to the biotechnology of the agricultural environment, as well as the use of biopesticides and the application of microorganisms to the mining, metal recovery and paper industries. This is the only comprehensive introductory account of this subject matter. Beginning with an introduction to microbial growth, An Introduction toEnvironmental Biotechnology aims to provide the non-specialist with a complete overview of environmental biotechnology. It is presented in an easy to read style with illustrations and includes frequent references to the use of higher plants as well as micro-organisms in environmental biotechnology. An Introduction to Environmental Biotechnology is geared toward a non-specialist audience, including engineers and environmental chemists, and environmental scientists who have limited knowledge of microbiology and biotechnology.  Free Download An Introduction to Electrical Engineering with Lab Activities English | 2025 | ISBN: 9815129309 | 544 pages | True PDF,EPUB | 382.58 MB Electrical engineering is an extremely broad and fast-changing profession that is rooted in many difficult concepts. Students might have a difficult time appreciating the relevance of the fundamental concepts that they are asked to grasp early in their education. Many difficult concepts are obscured by the traditional use of mathematics early in the treatments without sufficient exposure to the underlying meaning of the equations.  Free Download An Introduction to Dyslexia for Parents and Professionals By Alan M. Hultquist 2006 | 112 Pages | ISBN: 184310833X | PDF | 1 MB This practical guide provides basic need-to-know information for parents and professionals and answers frequently asked questions about dyslexia. Using illustrative case studies, Alan M. Hultquist addresses many of the issues surrounding dyslexia, including possible causes and subtypes, means of testing, remediation and the controversial matter of ''staying back'' to repeat a school year. He identifies possible methods of classroom accommodation for dyslexic students in a range of subject areas. The list of useful resources at the back of the book can be used by parents and professionals to help explain dyslexia to children, and to help them find further information and teaching tools. This complete introductory guide to dyslexia is a must'read for parents of children with dyslexia, especially parents with children who are newly diagnosed, and for all those who work with dyslexic children and their families.  Free Download An Introduction to Dirac Operators on Manifolds (Progress in Mathematical Physics №24) By Jan Cnops 2002 | 211 Pages | ISBN: 1461265967 | PDF | 5 MB Dirac operators play an important role in several domains of mathematics and physics, for example: index theory, elliptic pseudodifferential operators, electromagnetism, particle physics, and the representation theory of Lie groups. In this essentially self-contained work, the basic ideas underlying the concept of Dirac operators are explored. Starting with Clifford algebras and the fundamentals of differential geometry, the text focuses on two main properties, namely, conformal invariance, which determines the local behavior of the operator, and the unique continuation property dominating its global behavior. Spin groups and spinor bundles are covered, as well as the relations with their classical counterparts, orthogonal groups and Clifford bundles. The chapters on Clifford algebras and the fundamentals of differential geometry can be used as an introduction to the above topics, and are suitable for senior undergraduate and graduate students. The other chapters are also accessible at this level so that this text requires very little previous knowledge of the domains covered. The reader will benefit, however, from some knowledge of complex analysis, which gives the simplest example of a Dirac operator. More advanced readers---mathematical physicists, physicists and mathematicians from diverse areas---will appreciate the fresh approach to the theory as well as the new results on boundary value theory.  Free Download An Introduction to Differential Geometry - With the Use of Tensor Calculus English | March 23, 2011 | ASIN: B004R9PLZ4 | 317 pages | EPUB (True) | 13.81 MB Since 1909, when my Differential Geometry of Curves and Surfaces was published, the tensor calculus, which had previously been invented by Ricci, was adopted by Einstein in his General Theory of Relativity, and has been developed further in the study of Riemannian Geometry and various generalizations of the latter. In the present book the tensor calculus of cuclidean 3-space is developed and then generalized so as to apply to a Riemannian space of any number of dimensions. The tensor calculus as here developed is applied in Chapters III and IV to the study of differential geometry of surfaces in 3-space, the material treated being equivalent to what appears in general in the first eight chapters of my former book with such additions as follow from the introduction of the concept of parallelism of Levi-Civita and the content of the tensor calculus. Of the many exercises in the book some involve merely direct application of the text, but most of them constitute an extension of it. In the writing of the book I have received valuable assistance and criticism from Professor H. P. Robertson and from my students, Messrs. Isaac Battin, Albert J. Coleman, Douglas R. Crosby, John Giese, Donald C. May, and in particular, Wayne Johnson. The excellent line drawings and half-tone illustrations were conceived and executed by Mr. John H. Lewis.  Free Download An Introduction to Computational Fluid Dynamics: The Finite Volume Method By Henk Kaarle Versteeg; Weeratunge Malalasekera 2007 | 503 Pages | ISBN: 0131274988 | PDF | 12 MB This established, leading textbook, is suitable for courses in CFD.
