Book Description
The Book of R is a comprehensive, beginner-friendly guide to R, the world’s most popular programming language for statistical analysis. Even if you have no programming experience and little more than a grounding in the basics of mathematics, you’ll find everything you need to begin using R effectively for statistical analysis. You’ll start with the basics, like how to handle data and write simple programs, before moving on to more advanced topics, like producing statistical summaries of your data and performing statistical tests and modeling. You’ll even learn how to create impressive data visualizations with R’s basic graphics tools and contributed packages, like ggplot2 and ggvis, as well as interactive 3D visualizations using the rgl package. Dozens of hands-on exercises (with downloadable solutions) take you from theory to practice, as you learn: –The fundamentals of programming in R, including how to write data frames, create functions, and use variables, statements, and loops –Statistical concepts like exploratory data analysis, probabilities, hypothesis tests, and regression modeling, and how to execute them in R –How to access R’s thousands of functions, libraries, and data sets –How to draw valid and useful conclusions from your data –How to create publication-quality graphics of your results Combining detailed explanations with real-world examples and exercises, this book will provide you with a solid understanding of both statistics and the depth of R’s functionality. Make The Book of R your doorway into the growing world of data analysis.

Book Description
This monograph is devoted to long-range surface forces sig nificant far beyond a single monolayer and felt over tens or even hundreds of molecular layers adjacent to an interface. The transi tion from the concept of short-range effects that reigned earlier to the concept of long-range forces simultaneously signified the transition from a two-dimensional world to a three-dimensional one, incomparably richer in physicochemical phenomena. This transition took many years and evolved through many steps. It began with the Gouy-Chapman theory of diffuse ionic atmospheres, which together with London's theory of molecular forces was used as a basis for the development (beginning in 1937) of the DLVO theory of stability of lyophobic colloids. Further elaboration of the theory involved the introduction of new types of force, and a generalization (in 1954) to the case of interaction between unlike particles (hetero coagulation). This theory is fundamental in such large-scale prac tical problems as flotation, water treatment, dyeing, soil science, microbiology, and interaction between biological cells. This book is the first comprehensive monograph devoted to sur face forces. This fact makes it easier to attract the reader's interest; yet, the reader's demands become all the more difficult to satisfy completely. Indeed, the research that we review and analyze here covers about 50 years of work. Much data has been amassed, so that the main problem was a careful selection and an alysis.

Book Description
This second edition of EPA's bestselling book, Description and Sampling of Contaminated Soils: A Field Guide, Second Edition, has been revised and significantly expanded over the original edition. An ideal reference for anyone involved in site investigations, this guide describes how to determine the amount and extent of soil contamination and potential for movement of contaminants in the soil and groundwater. It contains checklists, tables, and step-by-step descriptions of methods and procedures for: Cost-effective, detailed site investigations for evaluating the potential for contaminant transport Field collection of information on soil engineering properties required for remediation selection and design This guide also features an adaptation of soil description procedures used by the U.S. Soil Conservation Service (SCS) for investigating contaminated sites. The SCS soil description and classification procedures, when used in combination with the Unified Soil Classification System currently used by geologists and engineers, greatly improves contaminated site assessments.
