This is a textbook for an introductory combinatorics course lasting one or two semesters. An extensive list of problems, ranging from routine exercises to research questions, is included. In each section, there are also exercises that contain material not explicitly discussed in the preceding text, so as to provide instructors with extra choices if they want to shift the emphasis of their course.Just as with the first two editions, the new edition walks the reader through the classic parts of combinatorial enumeration and graph theory, while also discussing some recent progress in the area: on the one hand, providing material that will help students learn the basic techniques, and on the oth...
This book provides a unique and unusual introduction to graph theory by one of the founding fathers, and will be of interest to all researchers in the subject. It is not intended as a comprehensive treatise, but rather as an account of those parts of the theory that have been of special interest to the author. Professor Tutte details his experience in the area, and provides a fascinating insight into how he was led to his theorems and the proofs he used. As well as being of historical interest it provides a useful starting point for research, with references to further suggested books as well as the original papers. The book starts by detailing the first problems worked on by Professor Tutte and his colleagues during his days as an undergraduate member of the Trinity Mathematical Society in Cambridge. It covers subjects such as comnbinatorial problems in chess, the algebraicization of graph theory, reconstruction of graphs, and the chromatic eigenvalues. In each case fascinating historical and biographical information about the author's research is provided.
In Anthropology of Tourism in Central and Eastern Europe: Bridging Worlds, Sabina Owsianowska and Magdalena Banaszkiewicz examine the limitations of the anthropological study of tourism, which stem from both the domination of researchers representing the Anglophone circle as well as the current state of tourism studies in Central and Eastern Europe. This edited collection contributes to the wider discussion of the geopolitics of knowledge through its focus on the anthropological background of tourism studies and its inclusion of contributors from Austria, Bulgaria, Estonia, and Poland.

The observed concentrations of pharmaceuticals and personal care products (PPCPs) in raw wastewater confirm that municipal wastewater represents the main disposal pathway for the PPCPs consumed in households, hospitals and industry. In sewage treatment plant effluents most PPCPs are still present, since many of these polar and persistent compounds are being removed only partially or, in some cases, not at all. Treated wastewater therefore represents an important point source for PPCPs into the environment. After passing a sewage treatment plant the treated wastewater is mostly discharged into rivers and streams or sometimes used to irrigate fields. If drinking water is produced using resourc...
The book is about history of Lithuania and Russia in Medieval Ages, about writing chronicles, and meanings of words used at the time. It is an analysis of over 30 volumes of the Full Collection of Russian Chronicles, that dates back to 855 A.D. The chronicles in Medieval Ages were written in Slavic using Cyrillic alphabet by monks of the Russian Orthodox Church and in Old German and Medieval Latin by monks of the Teutonic Order. Full texts from Lithuanian in Old Belorussian tongue and excerpts in translations from Russian and Teutonic are included. The book starts in 13th century Lithuania—the time Lithuania emerged as state. The analysis of chronicles takes its reader through said above r...
More than 10 years after the "First European Symposium on Organic Micropollutants in the Aquatic Environment", the "Sixth Symposium" was held in Lisbon (Portugal) from 22 to 24 May 1990. The Symposium was organised within the framework of the Concerted Action COST 641 * which is included in the Fourth R&D Programme on the Environment of the Commission of the European Communities expiring at the end of 1990. After restructuring the Concerted Action in 1984, particular attention has been devoted to fate and transformation of organic micropollutants in the aquatic environment. Therefore, a major aim of the Symposium was to review current studies and progress in these areas, besides more general...
The Life-Cycle of Pharmaceuticals in the Environment identifies pathways of entry of pharmaceuticals into the environment, beginning with the role of global prescribing and disposal practices. The book then discusses typical levels of common pharmaceuticals and how they can be determined in natural waters such as raw and treated sewage, and in potable water. In addition, sections examine methods currently available to degrade pharmaceuticals in natural waters and some of their ecotoxicological impacts, along with future considerations and the growing concept of product stewardship. - Encompasses the full lifecycle of common pharmaceuticals, from prescription and dispensing practices to their occurrence in a range of different types of natural waters and their environmental impact - Explores the role of the healthcare system and its affect on users - Beneficial for environmental engineers involved in the design and operation of appropriate degradation technologies of the pharmaceutical prescription and disposal practices
AS URGENT AS EVER: Nonpartisan policy recommendations and personal strategies for protecting against skyrocketing tax rates, reduced benefits, high inflation, and ruined currency. “Lays out in easy-to-understand prose why Social Security and Medicare need a comprehensive overhaul.” —Los Angeles Times In 2030, as 77 million baby boomers hobble into old age, walkers will outnumber strollers; there will be twice as many retirees as there are today but only 18% more workers. How will America handle this demographic overload? How will Social Security and Medicare function with fewer working taxpayers to support these programs? According to Laurence Kotlikoff and Scott Burns, we’ll see sky...
