In recent years there has been enormous activity in the theory of algebraic curves. Many long-standing problems have been solved using the general techniques developed in algebraic geometry during the 1950's and 1960's. Additionally, unexpected and deep connections between algebraic curves and differential equations have been uncovered, and these in turn shed light on other classical problems in curve theory. It seems fair to say that the theory of algebraic curves looks completely different now from how it appeared 15 years ago; in particular, our current state of knowledge repre sents a significant advance beyond the legacy left by the classical geometers such as Noether, Castelnuovo, Enriques, and Severi. These books give a presentation of one of the central areas of this recent activity; namely, the study of linear series on both a fixed curve (Volume I) and on a variable curve (Volume II). Our goal is to give a comprehensive and self-contained account of the extrinsic geometry of algebraic curves, which in our opinion constitutes the main geometric core of the recent advances in curve theory. Along the way we shall, of course, discuss appli cations of the theory of linear series to a number of classical topics (e.g., the geometry of the Riemann theta divisor) as well as to some of the current research (e.g., the Kodaira dimension of the moduli space of curves).
Challenge Windzer, the mixed-blood protagonist of this compelling autobiographical novel, was born at the beginning of the twentieth century "when the god of the great Osages was still dominate over the wild prairie and the blackjack hills" of northeast Oklahoma Territory. Named by his father to be "a challenge to the disinheritors of his people," Windzer finds it hard to fulfill his destiny, despite oil money, a university education, and the opportunities presented by the Great War and the roaring twenties. Critics have praised Sundown generously, both as a literary work and a vignette into the Native American past.
New Treatments of Leukemia and Lymphoma describes the most important advances in the therapy of hematopoietic cancers that have been derived from recent discoveries in cancer cell biology, kinase biochemistry, and immunology. Detailed descriptions of the large number of new and effective agents that have recently become available for the treatment of leukemias and lymphomas as well as an understanding of their mechanisms of action and their integration into current therapy are provided. A number of experimental drug reagents currently in clinical investigation are also discussed. The therapies include conventional anti-metabolites, monoclonal antibodies directed to cell surface receptors, antibodies tagged with toxins and radiopharmaceuticals, inhibitors of specific kinases, stem cell transplants, and engineered T-cells designed to selectively target hematopoietic cancers. The contents of the book will allow practitioners and investigators alike to understand what is current and state of the art as well as what to look for in the future.* Provides an up-to-date, state of the art discussion of a rapidly changing field * Great breadth covering conventional chemotherapeutic agents, biologic agents such as antibodies, novel small molecule inhibitors and genetically engineered cells * Written by international experts in each of the fields
This is an introduction to diophantine geometry at the advanced graduate level. The book contains a proof of the Mordell conjecture which will make it quite attractive to graduate students and professional mathematicians. In each part of the book, the reader will find numerous exercises.
This volume provides an analysis of what we know about turning around "failing" schools in the United States. It starts with an in-depth examination of the barriers that hinder action on turnaround work. The book analyses the reasons why some schools that find themselves in serious academic trouble fail in their efforts to turn themselves around. Beginning with a discussion of what may best be described as "lethal" reasons or the most powerful explanation for failed reform initiatives, which include an absence of attention to student care and support; a near absence of attention to curriculum and instruction; the firing of the wrong people. Covered in this volume are "critical" explanations for failed turnaround efforts such as failure to attend to issues of sustainability, and "significant" explanations for failed turnaround efforts such as the misuse of test data. The volume concludes by examining what can be done to overcome problems that cause failure for turnaround schools and reviewing ideas in the core technology of schooling: curriculum, instruction, and assessment. As well as exploring problems associated with the leadership and management of schools to see where improvement is possible and an analysis of opportunities found in relationships between schools and their external partners such as parents and community members.
Includes over 30 maps, photos and illustrations The Second Battle of Seoul was the battle to recapture Seoul from the North Koreans in late September 1950. The advance on Seoul was slow and bloody, after the landings at Inchon. The reason was the appearance in the Seoul area of two first-class fighting units of the North Korean People’s Army, the 78th Independent Infantry Regiment and 25th Infantry Brigade, about 7,000 troops in all. The NKPA launched a T-34 attack, which was trapped and destroyed, and a Yak bombing run in Incheon harbor, which did little damage. The NKPA attempted to stall the UN offensive to allow time to reinforce Seoul and withdraw troops from the south. Though warned that the process of taking Seoul would allow remaining NKPA forces in the south to escape, MacArthur felt that he was bound to honor promises given to the South Korean government to retake the capital as soon as possible. On September 22, the Marines entered Seoul to find it heavily fortified. Casualties mounted as the forces engaged in desperate house-to-house fighting. Anxious to pronounce the conquest of Seoul, Almond declared the city liberated on September 25 despite the fact that Marines were still engaged in house-to-house combat. Despite furious resistance by the North Korean forces, the Marines triumphed; pushing the communists soldiers out of Seoul. This U.S. Marine Corps history provides unique information about this important battle of the Korean War.
