Although sampling errors inevitably lead to analytical errors, the importance of sampling is often overlooked. The main purpose of this book is to enable the reader to identify every possible source of sampling error in order to derive practical rules to (a) completely suppress avoidable errors, and (b) minimise and estimate the effect of unavoidable errors. In short, the degree of representativeness of the sample can be known by applying these rules. The scope covers the derivation of theories of probabilistic sampling and of bed-blending from a complete theory of heterogeneity which is based on an original, very thorough, qualitative and quantitative analysis of the concepts of homogeneity and heterogeneity. All sampling errors result from the existence of one form or another of heterogeneity. Sampling theory is derived from the theory of heterogeneity by application of a probabilistic operator to a material whose heterogeneity has been characterized either by a simple scalar (a variance: zero-dimensional batches) or by a function (a variogram: one-dimensional batches). A theory of bed-blending (one-dimensional homogenizing) is then easily derived from the sampling theory. The book should be of interest to all analysts and to those dealing with quality, process control and monitoring, either for technical or for commercial purposes, and mineral processing. Although this book is primarily aimed at graduates, large portions of it are suitable for teaching sampling theory to undergraduates as it contains many practical examples provided by the author's 30-year experience as an international consultant. The book also contains useful source material for short courses in Industry.

Metalworking is generally regarded as a skill that takes years of dedication, requires a large studio space, and costs a lot of money. Fortunately, Simple Soldering proves that does not need to be the case. This handy how-to guide is complete in its exploration of the craft of creating soldered metal jewelry, including tools, techniques, and 20 beautiful projects that beginners and enthusiasts can make at home. Author and teacher Kate Richbourg demystifies basic soldering for any home crafter, showing how to create sophisticated, polished, and professional-looking jewelry pieces through simple soldering techniques. First, she instructs how to set up a jewelry workspace that fits the confines of your budget and living space. Detailed step-by-step instructions walk you through the basic tools and materials you need, plus how to use them. A sample chapter gives a host of introductory exercises that teach solid skills, allowing you to test these techniques on a small scale. Finally, you'll discover 20 finished projects that include earrings, pendants, rings, bracelets, and clasps that may also include bead or wire embellishment. Kate also demonstrates how to combine and layer techniques to gorgeous effect. She also examines common mistakes, shows how to correct or adapt them, and gives advice on when it's time to start over. Most of all, having taught thousands of classes on soldering, Kate has a "you can do it!" attitude that shines through to help even the most reluctant jewelry maker fire up the torch with ease. With Simple Soldering, the art of metal working one-of-a-kind jewelry is now at your fingertips.
