This is the exercise book accompanying Pressure Control During Drilling
Porous sedimentary formations penetrated by the rock bit contain fluids such as oil, gas or salt water. If the hydrostatic pressure of the drilling fluid drops below the formation pore pressure, pore fluid will enter the well and “kick” the mud out of the well. To control the pressure while drilling you need to understand the behavior of gas. This book aims at explaining the physics and the engineering approaches behind pressures in the sediments, detection of unstable wellbores, equipments necessary to close and kill the well, killing methods and offshore challenges

Food biopolymers: Structural, functional and nutraceutical properties provides valuable coverage of all major food biopolymers of from plant, animal and marine sources. The text focuses on the structural characteristics of biopolymers including starch, non-starch polysaccharides, proteins and fats. A full section is dedicated to the nutraceutical potential and applications of these polymers. Further sections provide comprehensive overviews of the development of functional food products and important data on biopolymer behavior and nutraceutical potential during processing. Researchers hoping to gain a basic understanding of the techno-functional, nutraceutical potential and applications of food biopolymers will find a singular source with this text. The first section of this work focuses on the the structure, functions, bioactivity and applications of starches. The next chapters cover non-starch polysaccharides. Further sections are dedicated to proteins, lipids and oils. A detailed overview is provided for each, followed by application procedures, specifics on individual types, proteins and enzymes, and nutraceutical properties. This work can be used as a singular source for all relevant information on food biopolymers and their structural and functional properties, including their potential to increase food quality, improve shelf life, and reduce pollution and waste in the food industry. .

The observational component of astronomy is an exciting and vital part of any astrophysics degree. With the advent of low-cost astronomical cameras and remote and robotic operation, more students than ever have the opportunity to observe and perform observatory research.
This updated and fully corrected textbook provides a comprehensive overview of practical observing techniques for undergraduate astrophysics courses. The chapters introduce students to the basics of the field before delving into telescope types, the nature and operation of the astronomical camera, imaging techniques and reduction, photometry and spectrography, and solar and radio observations.
The second edition covers the latest research on calibrating the telescope-camera-observatory system. It contains revised information on all available astronomy equipment, including filters, webcams, sensors, and telescope designs. Also included is an entirely new chapter on exoplanet transit measurements. The textbook’s practical approach will guide readers from basic first-year techniques to those required for a final-year project.

This book offers a comprehensive overview of recent theoretical studies on rhodium-catalyzed C-H functionalization, a topic that has attracted considerable attention over the years. It includes a brief experimental history, elementary reactions, and theoretical perspectives and describes in detail recent advanced computational studies on different types of Rh-catalyzed C-H functionalization, the underlying mechanisms, and the origin of regioselectivity in a series of such reactions. Providing examples shows readers how to use theoretical tools to solve problems related to mechanisms of organometallic reactions. As such, the book is an interesting and useful resource for a wide readership in various fields involving synthetic organic, organometallic, and catalysis reactions.

This book introduces readers to experimental techniques of general utility that can be used to practically and reliably determine nucleation rates. It also covers the basics of gas hydrates, phase equilibria, nucleation theory, crystal growth, and interfacial gaseous states. Given its scope, the book will be of interest to graduate students and researchers in the field of hydrate nucleation. The formation of gas hydrates is a first-order phase transition that begins with nucleation. Understanding nucleation is of interest to many working in the chemical and petroleum industry, since nucleation, while beneficial in many chemical processes, is also a concern in terms of flow assurance for oil and natural gas pipelines. A primary difficulty in the investigation of gas hydrate nucleation has been researchers' inability to determine and compare the nucleation rates of gas hydrates across systems with different scales and levels of complexity, which in turn has limited their ability to study the nucleation process itself. This book introduces readers to experimental techniques that can be used to practically and reliably determine the nucleation rates of gas hydrate systems. It also covers the basics of gas hydrates, phase equilibria, nucleation theory, crystal growth, and interfacial gaseous states. Given its scope, the book will be of interest to graduate students and researchers in the field of hydrate nucleation.

This book covers a wide range of topics on work function and band alignment, from the basics to practical examples. Work function and band alignment determine electric properties at the interface including surfaces, such as electron emission, the Schottky barrier height, and ohmic contact. Basic physics is used to systematically explain how to adjust and measure work function and how to modify the band alignment required for controlling work function in functional materials and electrodes. Methods introduced in the book help to improve device performance and to solve the problems of controlling the voltage and efficiency of devices in a great variety of applications, including electronic devices, optical devices such as displays, and energy devices such as solar cells and batteries. Understanding the technical methods necessary for controlling work function and band alignment can help to solve problems such as non-ohmic contact at source–electrode or drain–electrode interfaces in metal–oxide–silicon structures, which directly contributes to improving power saving and reducing heat generation in computers.

The third edition of the by now classic reference on rigorous analysis of symmetry breaking in both classical and quantum field theories adds new topics of relevance, in particular the effect of dynamical Coulomb delocalization, by which boundary conditions give rise to volume effects and to energy/mass gap in the Goldstone spectrum (plasmon spectrum, Anderson superconductivity, Higgs phenomenon). The book closes with a discussion of the physical meaning of global and local gauge symmetries and their breaking, with attention to the effect of gauge group topology in QCD.

This book focuses on the calculus of variations, including fundamental theories and applications.
This textbook is intended for graduate and higher-level college and university students, introducing them to the basic concepts and calculation methods used in the calculus of variations. It covers the preliminaries, variational problems with fixed boundaries, sufficient conditions of extrema of functionals, problems with undetermined boundaries, variational problems of conditional extrema, variational problems in parametric forms, variational principles, direct methods for variational problems, variational principles in mechanics and their applications, and variational problems of functionals with vector, tensor and Hamiltonian operators. Many of the contributions are based on the authors’ research, addressing topics such as the extension of the connotation of the Hilbert adjoint operator, definitions of the other three kinds of adjoint operators, the extremum function theorem of the complete functional, unified Euler equations in variational methods, variational theories of functionals with vectors, modulus of vectors, arbitrary order tensors, Hamiltonian operators and Hamiltonian operator strings, reconciling the Euler equations and the natural boundary conditions, and the application range of variational methods. The book is also a valuable reference resource for teachers as well as science and technology professionals
