Screening is regarded as a cost-effective and clinically useful approach for the early diagnosis of several malignancies, especially such common cancers as those of the breast and the cervix. This 1991 is a publication from the Project on evaluation of Screening for Cancer, organized by the International Union Against Cancer (UICC), one of the world's foremost agencies in the field of cancer epidemiology and control. It contains recommendations from the international authorities on cancers for which screening is used. Findings from studies in many countries are presented and evaluated, and methodological issues are also discussed. This is an influential and authoritative statement on the scope of cancer screening. It will be of interest to oncologists, epidemiologists and others in the public health field.

If you need a book that relates the core principles of quantum mechanics to modern applications in engineering, physics, and nanotechnology, this is it. Students will appreciate the book s applied emphasis, which illustrates theoretical concepts with examples of nanostructured materials, optics, and semiconductor devices. The many worked examples and more than 160 homework problems help students to problem solve and to practice applications of theory. Without assuming a prior knowledge of high-level physics or classical mechanics, the text introduces Schrodinger s equation, operators, and approximation methods. Systems, including the hydrogen atom and crystalline materials, are analyzed in detail. More advanced subjects, such as density matrices, quantum optics, and quantum information, are also covered. Practical applications and algorithms for the computational analysis of simple structures make this an ideal introduction to quantum mechanics for students of engineering, physics, nanotechnology, and other disciplines.
