The physical modelling of metal forming processes has been widely used both in University and in Industry for many years. Relatively simple numerical models, such as the Slab Method and the Upper Bound Method, were first used and many such models are implemented in the industry for practical design or regulation of forming processes. These are also under investigation in the University, mainly for treat models ments which require low cost calculations or very fast answers for on-line integration. More recently, sophisticated numerical methods have been used for the simulation of metal flow during forming operations. Since the early works in 1973 and 1974, mainly in U. K. and U. S. A. , the a...
In today’s connected world, the demand for mobile communications and instant access to information, anytime and anywhere, has drastically changed the electronics landscape, both consumer and industrial. Novel 5G and 6G systems will enable connectivity in all forms between humans, devices, machines, and any objects. They will provide virtually ubiquitous, ultra-high bandwidth and low latency network access to individual users, as well as to all objects benefiting from being connected. They will be the "eyes and ears" of Artificial Intelligence systems as it will provide real-time data collection and analysis. Such diversity calls for a new paradigm in terms of flexibility, not only related ...
This book reviews the recent development of fabrication methods and various properties of lotus-type porous metals and their applications. The nucleation and growth mechanism of the directional pores in metals are discussed in comparison with a model experiment of carbon dioxide pores in ice. Three casting techniques are introduced to produce not only metals and alloys but also intermetallic compounds, semiconductors, and ceramics: mold casting, continuous zone melting, and continuous casting. The latter has merits for mass production of lotus metals to control porosity, pore size and pore direction. Furthermore, anisotropic behavior of elastic, mechanical properties, thermal and electrical conductivity, magnetic properties, and biocompatibility are introduced as peculiar features of lotus metals.
This book reviews different aspects of the cancer microenvironment, and its regulation and importance for tumor progression. Methodological advancements and practical applications, in terms of how biomarkers are studied and increasingly included in clinical trials and therapy protocols, are described and discussed. Biomarkers of the Tumor Microenvironment is an educational resource for students and members of the cancer research community as a whole, especially for those using morphology analysis techniques and models focusing on the cross-talk between different cell types in tumors. The textbook provides a comprehensive overview of the microenvironment in various contexts from the perspectives of experienced and accomplished cancer researchers and clinicians.
Now in a much-anticipated two-volume new edition, this gold-standard reference stands as the most comprehensive and authoritative text on equine reproduction. Serving theriogenologists, practitioners and breeders worldwide as a one-stop resource for the reproductive assessment and management of equine patients, Equine Reproduction, Second Edition provides detailed information on examination techniques, breeding procedures, pregnancy diagnosis and management, reproductive tract diseases and surgery, and foaling. A companion website offers hundreds of images from the book in color. For the Second Edition, the stallion, mare and foal sections have been thoroughly updated and revised to include the latest information on every subject. New topics include discussion of nutritional and behavioral factors in the broodmare and stallion, parentage testing, fetal sexing and the health and management of older foals, weanlings and yearlings. Additionally, this outstanding Second Edition features a new section on assisted reproductive techniques, including detailed information on artificial insemination, in-vitro fertilization, embryo transfer and technology.
