It is common these days for a single system to host many domains, for example uniswa.com and mtn.com or acme .com may run on a single host machine, but behave as if they were on three different hosts. A system usually has a canonical domain, it has its usual or local domain name, and additional domains are configured as virtual domains. The purpose behind this work is to create a mail server solution based on Postfix that is based on virtual users and domains, i..e. users and domains that are in...

In Judgments of Beauty in Theory Evaluation , Devon Brickhouse-Bryson argues that judgments of beauty are a justified part of theory evaluation of all sorts, including both scientific theory evaluation and philosophical theory evaluation. He supports this argument with an account of beauty—inherited from Kant and Mothersill—on which the distinctive nature of judgments of beauty is that they are unprincipled, yet possible. Brickhouse-Bryson analyzes two important methods of...

Truth used to be based on reason. No more. What we feel is now the truest source of reality. Despite our obsession with the emotive and the experiential, we still face anxiety, despair, and purposelessness.How did we get here? And where do we find a remedy? In this modern classic, Francis A. Schaeffer traces trends in twentieth-century thought and unpacks how key ideas have shaped our society. Wide-ranging in his analysis, Schaeffer examines philosophy, science, art, and popular culture to...

Gradiometry is a multidisciplinary area that combines theoretical and applied physics, ultra-low noise electronics, precision engineering, and advanced signal processing. All physical fields have spatial gradients that fall with distance from their sources more rapidly than the field strength itself. This makes the gradient measurements more difficult. However, there has been a considerable investment, both in terms of time and money, into the development of various types of gradiometers driven...

Atomic Physics provides a concise treatment of atomic physics and a basis to prepare for work in other disciplines that are underpinned by atomic physics such as chemistry, biology and several aspects of engineering science. The focus is mainly on atomic structure since this is what is primarily responsible for the physical properties of atoms. After a brief introduction to some basic concepts, the perturbation theory approach follows the hierarchy of interactions starting with the largest. The...

Partial differential equations arise in many branches of science and they vary in many ways. No one method can be used to solve all of them, and only a small percentage have been solved. This book examines the general linear partial differential equation of arbitrary order m. Even this involves more methods than are known. We ask a simple question: when can an equation be solved and how many solutions does it have?The answer is surprising even for equations with constant coefficients. We begin...

Dissecting the hype from the frontiers of bioethics, genomics and neuroscience. Our fates lie in our genes and not in the stars, said James Watson, co-discoverer of the structure of DNA. But Watson could not have predicted the scale of the industry now dedicated to this new frontier. Since the launch of the multibillion-dollar Human Genome Project, the biosciences have promised miracle cures and radical new ways of understanding who we are. But where is the new world we were promised? In Genes,...

This book explains to the general reader the roles of chemistry in various areas of life ranging from the entirely personal to the worryingly global. These roles are currently not widely appreciated and certainly not well understood. The book is aimed at educated laypeople who want to know more about the world around them but have little chemical knowledge. The themes relate to the importance of chemistry in everyday life, the benefits they currently bring, and how their use can continue on a...

Demonstrating the timely relevance of Theodore Dreiser, Edith Wharton, Jack London and Henry Adams, this book shows how debates about evolution, identity, and a shifting world picture have uncanny parallels with the emerging global systems that shape our own lives. Tracing these systems’ take-off point in the early twentieth century through the lens of popular science journalism, John Bruni makes a valuable contribution to the study of how biopolitical control over life created boundaries among...

Modern economies are full of uncertainties and risk. Economics studies resource allocations in an uncertain market environment. As a generally applicable quantitative analytic tool for uncertain events, probability and statistics have been playing an important role in economic research. Econometrics is statistical analysis of economic and financial data. In the past four decades or so, economics has witnessed a so-called 'empirical revolution' in its research paradigm, and as the main...

Customarily, the framework of algebraic geometry has been worked over an algebraically closed field of characteristic zero, say, over the complex number field. However, over a field of positive characteristics, many unpredictable phenomena arise where analyses will lead to further developments.In the present book, we consider first the forms of the affine line or the additive group, classification of such forms and detailed analysis. The forms of the affine line considered over the function...
