Multimedia Environmental Models: The Fugacity Approach, Third Edition, takes a broad approach of viewing chemical behavior in the total biosphere of connected biotic and abiotic compartments. Chemicals are subject to the laws of "mass balance," a constraint that provides the opportunity to establish quantitative expressions for chemical fate that are central to chemical management and regulatory legislation. This book employs both the conventional concentration-based procedures and those based on application of the more elegant and powerful concept of fugacity to characterize equilibrium, steady-state distribution, and time-dependent transport between environmental phases such as air, water, and soil. Organic chemicals are emphasized because they are more easily generalized when assessing environmental behavior.Features Illustrates professional approaches to calculating the fate of chemicals in the environment Explicitly details all worked examples in an annotated step-by-step fashion Presents real-life freely downloadable models of use to government, industry, and private consulting professionals and students alike Clarifies symbols and notation

A comprehensive account of the state of the science of environmental mass transportEdited by Louis J. Thibodeaux and Donald Mackay, renowned experts in this field, the Handbook of Chemical Mass Transport in the Environment covers those processes which are critically important for assessing chemical fate, exposure, and risk. In a comprehensive and authoritative format, this unique handbook provides environmental chemists, geoscientists, engineers, and modelers with the essential capabilities to understand and quantify transport. In addition, it offers a one-stop resource on environmental mass transfer and mass transport coefficient estimation methods for all genres. The book begins by discussing mass transport fundamentals from an environmental perspective. It introduces the concept of mobility — key to environmental fate, since transport must occur prior to any reaction or partitioning within the natural multimedia compartments. The fugacity approach to environmental mass transfer and the conventional approach are examined. This is followed by a description of the individual mass transport processes and the appropriate flux equations required for a quantitative expression. The editors have identified 41 individual processes believed to be the most environmentally significant, which form the basis for the remainder of the book Using a consistent format for easy reference, each chapter:Introduces the specific processes Provides a detailed qualitative description Presents key theoretical mathematical formulations Describes field or laboratory measurements of transport parametersGives data tables and algorithms for numerical estimates Offers a guide for users familiar with the process who are seeking a direct pathway to obtain the numerical coefficientsPresents computed example problems, case studies and/or exercises with worked-through solutions and answersThe final chapter presents the editors’ insight into future needs and emerging priorities. Accessible and relevant to a broad range of science and engineering users, this volume captures the state of the transport science and practice in this critical area.

Multimedia environmental models are powerful tools for predicting the fate and distribution of chemicals in the environment. They are used for assessing the potential exposure of ecosystems and humans to contaminants, as well as for developing and evaluating chemical management approaches. This book has been developed with the aim of providing support to students and researchers who are new to fugacity-based environmental modelling or wish to refresh their knowledge and skills. The nature and approach of fugacity-based calculations is developed methodically and sequentially from very first steps, with computational details explicitly shown and discussed. Whereas our text "e;Multimedia Environmental Models: The Fugacity Approach"e; gives detailed justification for the theoretical underpinnings of the fugacity approach, this workbook instead focusses on the step-by-step exposition of computational details and approaches without excessive theoretical justification. We believe that this approach will serve to help clarify the necessary computational steps and approaches needed to design and implement fugacity-based computations in real-life environmental contexts.Key Features Step-by step development of computations and models Sequenced introduction of topics to help develop computational facility Screen-shots of model and worksheet calculations with equations revealed for clarity Explicitly detailed calculations and methodology Many examples chosen from published works of realistic applications.

Short-listed for the 1978 Governor General’s Award for Non-Fiction The 19th century spawned a unique breed of men who took pride in their woodsmen skills and rough codes of conduct. They called themselves lumberers, shantymen, timber beasts, les bucherons – and, more recently, lumberjacks, working in the vast forests of eastern Canada and British Columbia. Across the country, farm boys would go to the woods, lumbering being the only winter work available. Immigrants – Swedes and Finns more often than not – resumed the trades they had learned so well in the forests of northern Europe. They broke the cold, hard monotony of camp life with songs, tall tales and card games. Within these pages, author Donald MacKay allows us a glimpse into that moment in our heritage when men entered the virgin forest to carve out an industry from the seemingly endless array of pine, spruce, maple and balsam fir found there.

This is the story of the Highland Scots who sailed to Pictou, Nova Scotia, in 1773 aboard the brig Hector. These intrepid emigrants came for many reasons: the famine of the previous spring, pressures of population growth, intolerable rent increases, trouble with the law, the hunger of landless men to own land of their own. Upon arrival at Pictou, after an appalling storm-tossed crossing, they found they had been deceived. The promised prime farming land turned out to be virgin forest. Only the kindness of the Mi'kmaq and the few New Englanders already settled there enabled them to survive until they learned how to exploit the forests and clear land. But survive they did, and their prosperity encouraged shiploads of emigrants, many fellow clansmen, to join them, making northeastern Nova Scotia a true New Scotland.

It was suggested to the author of this book of short stories that he relate his education accomplishments and high points in his life as it related to writing. Universities, and there were several, creative writing as far as those were available to an old student. He served four years active and four years reserve in the military. At fifty six he decided to graduate from high school. He had already been to three universities, learning Spanish, Russian, and Latin, and had taken a first course in creative writing. It was the first, of several rather unsteady steps, to a possible life of writing short stories. After graduating from high school he proceeded to move from one university creative writing course to another until he reached the university of N.C. at Chapel Hill with a professor, a well known writer, who taught advanced creative writing . It was required that a demonstration of writing ability needed to be offered before a student would be accepted to his class. MR. MacKay was accepted and presented many stories to the professor who was well taken with the creative talent demonstrated. It was the most positive acceptance by a professional writer and a compliment beyond any this writer had ever received. This is book #5 of a list of 8. Maybe he could be an accepted writer; that remains to be seen. Readers will make that judgment.

I've made all my choices freely in this life, but how I wish they were all perfect without errors. Only in the last fifteen years can I say I have chosen, not perfectly mind you, but wisely. All my choices are now founded upon reason and common sense and logic and a belief in an actual Creator, which is a philosophy called Deism. Unlike revealed religious beliefs that seek to isolate mankind and to sever the tie that binds one human to another, Deism never makes demands. Deists are instead individuals who choose to stand alone in their trust in the Creator. Paradise or Heaven, should there be such places, are reserved for religious believers. The rest of humanity? Deism seeks to unite mankind with a universal truth that all can accept not founded on a book called holy created by mankind to control mankind. Deism looks to the Cosmos, Nature, and the endlessness of the night's sky, each as a book to help guide mankind. Deism does not require a promise or a reward of Heaven or Paradise as an incentive to be a good and loving person; it is simply the right thing to do. We all shall see truth if there is anything to see in the by and by. Perhaps, we will simply go to a deep, dreamless sleep and know nothing more as a few souls believe? I really don't know what happens at the last moment; even so, I will maintain my trust in the Creator to the very end. I shall hold to reason and common sense until my time here is ended.
