"This book covers the modular invariant theory of finite groups, the case when the characteristic of the field divides the order of the group. It explains a theory that is more complicated than the study of the classical non-modular case, and it describes many open questions. Largely self-contained, the book develops the theory from its origins up to modern results. It explores many examples, illustrating the theory and its contrast with the better understood non-modular setting. It details techniques for the computation of invariants for many modular representations of finite groups, especially the case of the cyclic group of prime order. It includes detailed examples of many topics as well as a quick survey of the elements of algebraic geometry and commutative algebra as they apply to invariant theory. The book is aimed at both graduate students and researchers--an introduction to many important topics in modern algebra within a concrete setting for the former, an exploration of a fascinating subfield of algebraic geometry for the latter"--back cover.

An international treaty banning the testing of any nuclear device in any environment - a comprehensive test ban treaty (CTBT) - has been on the political agenda for nearly 40 years. Objections to a CTBT have been political, technical, or a combination of both. However, the possibilities seem better after the end of the Cold War. In the prevailing, cooperative disarmament climate a CTBT appears likely to be approved by most countries in 1996. Hence the great current interest in monitoring technologies and capabilities. Such issues are comprehensively addressed here, a preamble being devoted to the political developments and setbacks over the past 40 years. Since seismic means are considered the dominant monitoring element, they are explored in detail. Contributions cover network deployments, advanced signal processing, wave propagation in heterogeneous media, and seismic source representations, and a variety of techniques for source classification (including neural networks). Complementary monitoring techniques, such as hydroacoustics, radionuclides and infrasound, are also summarised. The IAEA operation for monitoring compliance with the Non-Proliferation Treaty is also presented. The book also includes eyewitness accounts of the Soviet 50 Mt megabomb development and test, as well as the efforts made by the state to monitor the nuclear test programmes of the western powers. Includes some 33 articles written by distinguished scientists active in CTBT monitoring research for decades.

Sybilla Beckmann

Mathematics for Future Elementary Teachers with Activities, 5th Edition connects the foundations of teaching elementary math and the “why” behind procedures, formulas and reasoning so students gain a deeper understanding to bring into their own classrooms. Through her text, Beckmann teaches mathematical principles while addressing the realities of being a teacher. With in-class collaboration and activities, she challenges students to be actively engaged. An inquiry-based approach to this course allows future teachers to learn through exploration and group work, leading to a deeper understanding of mathematics. Known for her contributions in math education, Beckmann writes the leading text for the inquiry approach; in Mathematics for Elementary Teachers with Activities, students engage, explore, discuss, and ultimately reach a true understanding of mathematics. Beckmann’s text covers the Common Core State Standards for Mathematics (CCSSM) now implemented in most states. However, states not following Common Core will not find the information intrusive in the text.

M.J. Ross

During the first half of the nineteenth century British explorers eagerly sought the Northwest Passage, making great advances in exploring and charting polar regions. Polar Pioneers is the story of John Ross and his nephew James Clark Ross, British naval officers who made important contributions to world exploration. In 1818 John Ross led an expedition to search for the Northwest Passage. He got as far as Baffin Bay, but when he reached the only practicable entrance to the passage he declared it to be no more than a bay enclosed by mountains. In subsequent years he was widely derided for that error and carried the scars of public and professional humiliation for the rest of his life. In 1829 he mounted a private expedition to search for the passage, during which he became trapped in the Canadian Arctic and survived a four-year ordeal of isolation and hardship. He proved that whatever his shortcomings as an explorer, he could never be accused of lacking courage. . James Clark Ross was one of the most experienced and respected explorers of his day. He led or took part in eight expeditions to the Arctic, including John Ross's 1818 and 1829 expeditions and three with the great explorer William Edward Parry. He also led a highly successful scientific expedition to the Antarctic in 1839-43. His many important discoveries included locating the North Magnetic Pole, and he ensured the presence of the Ross family name throughout both polar regions: Ross Island, Ross Ice Shelf, and Ross Sea in the Antarctic; James Ross Strait, Ross Bay, Ross Point, and Rossoya in the Arctic.
