Viral Ecology

Viral Ecology defines and explains the ecology of viruses by examining their interactions with their hosting species, including the types of transmission cycles that have evolved, encompassing principal and alternate hosts, vehicles, and vectors. It examines virology from an organismal biology approach, focusing on the concept that viral infections represent areas of overlap in the ecology of viruses, their hosts, and their vectors. Key Features * The relationship between viruses and their hosting species * The concept that viral interactions with their hosts represents a highly evolved aspect of organismal biology * The types of transmission cycles which exist for viruses, including their hosts, vectors, and vehicles * The concept that viral infections represent areas of overlap in the ecology of the viruses, their hosts, and their vectors

Biotechniques for Air Pollution Control

Proceedings of the 3rd International Congress on Biotechniques for Air Pollution Control. Delft, The Netherlands, September 28-30, 2009

Energy and feedstock materials for the chemical industry show an increasing demand. With constraints related to availability and use of oil, the energy and chemical industry is subject to considerable changes. The need for the use of cheaper and widely available feedstocks, and the development of sustainable and environmentally friendly chemical processes is growing rapidly under both economical and public pressure. Therefore, waste gas treatment has gradually been integrated into the process design. Instead of discharging their waste gases into the atmosphere, industries increasingly attempt to become self-sufficient and recover compounds from their own wastestreams or use (upgraded) wastestreams of neighbouring industries as raw material. The proceedings of the 3rd International Symposium on Biotechniques for Air Pollution Control, held on 28-30 September 2009 in Delft, the Netherlands, give an overview of innovative biotechnology based processes for treatment of waste gasses. Various innovative research aspects of environmental chemistry, environmental engineering, and bioprocess technology are discussed.

Signals and Systems Analysis In Biomedical Engineering, Second Edition

The first edition of this text, based on the author’s 30 years of teaching and research on neurosensory systems, helped biomedical engineering students and professionals strengthen their skills in the common network of applied mathematics that ties together the diverse disciplines that comprise this field. Updated and revised to include new material as the field has grown, Signals and Systems Analysis in Biomedical Engineering, Second Edition continues to provide a ready source of information on those specialized mathematical techniques most useful in describing and analyzing biomedical signals. New chapters on nonlinear and complex systems Enriched with many examples that promote sound practical analysis, this volume covers classical linear systems theory and its applications to biomedicine. It examines the important use of joint time-frequency analysis to characterize non-stationary physiological signals, and explores the mathematics of tomographic imaging (the Radon transform, the Fourier slice theorem, and the filtered back-projection algorithm). It also describes the analytical signal and the Hilbert transform and some of its biomedical applications. New chapters in this edition include one on the analysis of nonlinear biochemical systems and biochemical oscillators, as well as one introducing complex systems and illustrating ways to best model them. Four appendices with additional material Extensive appendices supplement the text, including "Simnon® Programs Used in Chapters 11 and 12," "How to use Root Locus to Determine the Stability of SISO Linear Systems," "Signal Flow Graphs and Mason’s Rule," and "Computational Tools for Biomedical Signal Processing and Systems Analysis." An extensive glossary is included as well as an ample listing of sources for further study. A solutions manual is available for instructors wishing to convert this refrence to classroom use.

Signals and Systems Analysis In Biomedical Engineering

The interdisciplinary field of biomedical engineering requires its practitioners to master not only engineering skills, but also a diversity of material in the biological sciences. This text helps biomedical engineers strengthen their skills in the common network of applied mathematics that ties together these diverse disciplines. Based on the author's 30 years of experience in teaching as well as his personal research on neurosensory systems, Signals and Systems Analysis in Biomedical Engineering provides a ready source of information on those specialized mathematical techniques most useful in describing and analyzing biomedical signals, including ECG, EEG, blood pressure, biochemical spectrograms, and tomographic images. Enriched with many examples that promote sound practical analysis, this book: Presents the traditional systems mathematics used to characterize linear time-invariant (LTI) systems and, given inputs, find their outputs Explains the relations between impulse response, real convolution, transfer functions and frequency response functions Reviews specialized mathematical techniques used to characterize and model nonlinear systems Introduces the basic mathematical tools used to describe noise and how it propagates through LTI and NLTI systems Describes how signal-to-noise ratio can be improved by signal averaging and linear and nonlinear filtering

7.1 Introduction This chapter will introduce an important mathematical tool for
describing nonstationary (NS) biomedical signals; i.e., joint time-frequency
analysis (JTFA). The following sections describe various transforms used to make

The Essential Physics of Medical Imaging

This renowned work is derived from the authors' acclaimed national review course (“Physics of Medical Imaging") at the University of California-Davis for radiology residents. The text is a guide to the fundamental principles of medical imaging physics, radiation protection and radiation biology, with complex topics presented in the clear and concise manner and style for which these authors are known. Coverage includes the production, characteristics and interactions of ionizing radiation used in medical imaging and the imaging modalities in which they are used, including radiography, mammography, fluoroscopy, computed tomography and nuclear medicine. Special attention is paid to optimizing patient dose in each of these modalities. Sections of the book address topics common to all forms of diagnostic imaging, including image quality and medical informatics as well as the non-ionizing medical imaging modalities of MRI and ultrasound. The basic science important to nuclear imaging, including the nature and production of radioactivity, internal dosimetry and radiation detection and measurement, are presented clearly and concisely. Current concepts in the fields of radiation biology and radiation protection relevant to medical imaging, and a number of helpful appendices complete this comprehensive textbook. The text is enhanced by numerous full color charts, tables, images and superb illustrations that reinforce central concepts. The book is ideal for medical imaging professionals, and teachers and students in medical physics and biomedical engineering. Radiology residents will find this text especially useful in bolstering their understanding of imaging physics and related topics prior to board exams.

Essential Hypertension and Its Causes

Neural and Non-Neural Mechanisms

Essential hypertension (EH) is the most common type of high blood pressure and is responsible for much death and serious illness, which has been the reason for the huge research effort to determine its causes. However, countless scientific articles still keep proclaiming that "the causese of essential hypertension remain unknown." In view of the number of publications that descend on the hypertension specialist like a waterfall, such proclamations seem to overlook the considerable amount of knowledge that we already have about the etiology of EH. The problem may be a lack of synthesis rather than a lack of information. This book brings together some of this knowledge into a coherent and clinically relevant account about the pathogenesis of EH. With an extremely broad reach, this book aims to give a balanced view of the causes of EH, its neural, genetic, and environmental causes.

Hence, each type of hypertension merits detailed analysis of its underlying
mechanisms. The neural cardiovascular control system is a nonlinear adaptive
system. Sometimes the neural parameter changes come automatically into play
