Pragmatic Introduction To The Finite Element Method For Thermal And Stress Analysis, A: With The Matlab Toolkit Sofea

By: Petr Krysl

This textbook provides an accessible and self-contained description of the Galerkin finite element method for the two important models of continuum mechanics, transient heat conduction and elastodynamics, from formulation of the governing equations to implementation in Matlab.The coverage follows an intuitive approach: the salient features of each initial boundary value problem are reviewed, including a thorough description of the boundary conditions; the method of weighted residuals is applied to derive the discrete equations; and clear examples are introduced to illustrate the method.

Yield Formation in the Main Field Crops

By: V. Cerný,L. Hruška,J. Petr

This book gives a detailed overview of production processes and yield formation in field crops and permanent grasslands. Yield formation is discussed by the authors as a dynamic process, involving many factors at each stage. Knowledge of the optimum levels of individual yield components makes it possible to control this dynamic process. It is intended that this approach will help to point out gaps in the understanding of the production processes and indicate the direction for further research on this subject.The authors report on various aspects which are involved in yield formation, such as uptake of nutrients, root growth, water use, photosynthesis, transport, distribution and accumulation of photosynthates, etc. A separate chapter discusses the production process as seen from a genetic standpoint. It includes an analysis of phenotype and genotype with respect to production potential, also the heredity, variability of yield potential and new cultivation methods are mentioned. The main part of the book deals with the theory and practice of yield formation in cereals, maize, legumes, sugarbeet, potatoes, clovers and perennial grass stands.

Ultra-Low Field Nuclear Magnetic Resonance

A New MRI Regime

By: Robert Kraus Jr.,Michelle Espy,Per Magnelind,Petr Volegov

This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Apatites and their Synthetic Analogues

Synthesis, Structure, Properties and Applications

By: Petr Ptáček

Apatite-type minerals and their synthetic analogues are of interest of many industrial branches and scientific disciplines including material sciences, chemical industry, agriculture, geology, medicine and dentistry. This book provides a basic overview of general knowledges of this topic in order to provide the comprehensive survey from a scientific and technological perspective. The book is divided into 10 chapters, which are devoted to the structure and properties of minerals from the supergroup of apatite, experimental techniques of preparation and characterization of synthetic analogues of apatite minerals, substitution in the structure of apatite as well as utilization of these materials in wide range of common and special advanced applications in industry, material sciences and research. Additionally, the phosphate rocks, their classification, geological role, mining and beneficiation of phosphate ore, production of elemental phosphorus, phosphoric acid and fertilizers are also described. Although this book is meant for chemist, material scientist and research engineers, the individual chapters contain theoretical background, historical aspects as well as examples of synthetic and analytical methods which may be also interesting for students and non-expert readers as well.

Organic Polarographic Analysis

International Series of Monographs on Analytical Chemistry

By: Petr Zuman

Organic Polarographic Analysis deals with the applications of polarography in the analysis of organic compounds. The principles, techniques, and apparatus of organic polarography are discussed, and some selected examples of the applications of organic polarography in various fields of applied chemistry are presented. The direct methods in which the sample is simply dissolved in a suitable supporting electrolyte are also considered. This book consists of 11 chapters and opens with an overview of the basic principles of the polarographic method of analysis, as well as the different types of polarographic limiting currents and of electrode processes. The reader is then introduced to the instruments used in polarography, including the polarograph, dropping and reference electrodes, and electrolysis vessels. Experimental techniques in organic polarography are also described, along with some of its practical applications in fields such as pharmacy, medicine, and biochemistry. Subsequent chapters explore polarographic methods used in the analysis of organic substances, including direct and indirect methods of analysis; separation techniques; and the use of polarography in organic synthesis and isolation of natural products. This monograph is written primarily for organic and analytical chemists.

Physics of Massive Neutrinos

By: Felix Boehm,Petr Vogel

Neutrinos play a decisive part in nuclear and elementary particle physics, as well as in astrophysics and cosmology. Some of their most basic properties, such as their mass and charge conjugation symmetry, are largely unknown. This book focuses on what we know and may hope to know about the mass of the neutrino and its particle-antiparticle symmetry. Topics include neutrino mixing, neutrino decay, neutrino oscillations, double beta decay, solar neutrinos, supernova neutrinos and related issues. The authors stress the physical concepts, and discuss both theoretical and experimental techniques. This updated second edition differs from the first in that it contains an expanded coverage of experimental results and theoretical advances. Since publication of the first edition, many issues that were at that time unresolved, such as tritium beta decay and reactor neutrino oscillations, have been clarified and are discussed here. Also included is an expanded coverage of solar and supernova neutrinos. This book deals with one of the most intriguing issues in modern physics, and will be of value to researchers, graduate students and advanced undergraduates specializing in experimental and theoretical particle physics and nuclear physics.
