Semisolid metallurgy (SSM) is now some 37-years-old in terms of time from its conception and ?rst reduction to practice in the laboratory. In the intervening years, there has been a steadily growing body of research on the subject and the beginning of signi?cant industrial applications. The overall ?eld of SSM comprises today a large number of speci?c process routes, almost all of which fall in the category of either “Rheocasting” or Thi- casting.” The former begins with liquid metal and involves agitation during partial solidi?cation followed by forming. The latter begins with solid metal of suitable structure and involves heating to the desired fraction solid and forming. Research over the past 37 years, and particularly over the last decade, has provided a detailed picture of process fundamentals and led to a wide range of speci?c SSM processes and process innovations. Industrial studies and actual p- duction experience are providing a growing picture of the process advantages and limitations. At this time, the conditions for eventual wide adoption of SSM appear favorable, both for nonferrous and ferrous alloys. It must, however, be recognized that major innovations, such as SSM become adopted only slowly by industries where capital costsarehigh,pro?tmarginsaremodest,andfailuretomeetcustomercommitments carries a high penalty.
There is a comforting tale that heads of higher education institutions (HEIs) like to tell each other. "Go around your university or college," they say, "and ask the first ten people who you meet how their morale is. The response will always be 'rock-bottom.' Then ask them what they are working on. The responses will be full of life, of optimism and of enthusiasm for the task in hand." The moral of the story is that the two sets of responses don't compute; that the first is somehow unthinking and ideological, and the second unguarded and sincere. The thesis of this book is that the contradictory answers may well compute more effectively than is acknowledged: that the culture of higher education and the mesh of psychological contracts, or "deals," that make it up make much of the current discourse about happiness and unhappiness in contemporary life look simplistic and banal. In particular, the much-vaunted "science of happiness" may not have much to say to us. There is also a potential link between the Manichean discourse about morale and our wider culture's approach to happiness. Both normally deal in extremes, and much more rarely in graduations. Why is so much discourse about contemporary higher education structured around (real and imagined) unhappiness? How does this connect with the realities of life within (and just outside) the institutions? Does it matter, and, if so, what should we be doing about it? Based on historical, sociological and philosophical analysis, this book offers some answers to these questions.
The Engaged University is a comprehensive empirical account of the global civic engagement movement in higher education. In universities around the world, something extraordinary is underway. Mobilizing their human and intellectual resources, institutions of higher education are directly tackling community problems – combating poverty, improving public health, and restoring environmental quality. This book documents and analyzes this exciting trend through studies of civic engagement and social responsibility at twenty institutions worldwide. This timely volume offers three special contributions to the literature on higher education policy and practice: a historical overview of the founding purposes of universities, which almost invariably included a context-specific element of social purpose, together with a survey of how these "founding" intentions have fared in different systems of higher education; a contemporary account of the policy and practice of universities – all over the world – seeking to re-engage with this social purpose; and an overview of generic issues which emerge for the "engaged university.

Linear Methods: A General Education Course is expressly written for non-mathematical students, particularly freshmen taking a required core mathematics course. Rather than covering a hodgepodge of different topics as is typical for a core mathematics course, this text encourages students to explore one particular branch of mathematics, elementary linear algebra, in some depth. The material is presented in an accessible manner, as opposed to a traditional overly rigorous approach. While introducing students to useful topics in linear algebra, the book also includes a gentle introduction to more abstract facets of the subject. Many relevant uses of linear algebra in today’s world are illustrated, including applications involving business, economics, elementary graph theory, Markov chains, linear regression and least-squares polynomials, geometric transformations, and elementary physics. The authors have included proofs of various important elementary theorems and properties which provide readers with the reasoning behind these results. Features: Written for a general education core course in introductory mathematics Introduces elementary linear algebra concepts to non-mathematics majors Provides an informal introduction to elementary proofs involving matrices and vectors Includes useful applications from linear algebra related to business, graph theory, regression, and elementary physics Authors Bio: David Hecker is a Professor of Mathematics at Saint Joseph's University in Philadelphia. He received his Ph.D. from Rutgers University and has published several journal articles. He also co-authored several editions of Elementary Linear Algebra with Stephen Andrilli.

Add Expert Analysis of Difficult Cases to Your Practice With Consultant Pathology Superficial Melanocytic Pathology provides expert guidance for resolving the real world problems pathologists face when diagnosing melanomas and other atypical pigmented lesions. It reviews each major category of atypical melanocytic lesions, including the pathology of the superficial categories of melanoma followed by a discussion of the major simulants of melanoma. The book provides an overview of the morphologic description and diagnostic issues for each lesion, followed by 60 detailed, abundantly illustrated case presentations, offering an expert approach to diagnosis for a range of challenging cases. Five hundred high-quality color images support the case presentations. Of special interest is a chapter on "ambiguous" lesions of uncertain significance. The book's thorough analysis of challenging lesions will aid pathologists in differentiating between benign superficial proliferations and malignant melanocytic tumors. All Consultant Pathology Titles Provide: ACTUAL consultation cases and expert analysis EXPERT analysis provides a detailed discussion of the reasoning behind the diagnosis of each case COMPREHENSIVE coverage of challenging diagnoses CASES that are richly illustrated with high-quality photomicrographs
The key role of histopathology in analysis of a melanocytic tumor is the recognition or exclusion of a malignant melanoma. The analysis of typical features leads to a correct diagnosis in the majority of cases. However, there are cases that are problematic, because of conflicting or insufficient criteria, in which a confident diagnosis is difficult. These difficult lesions account for a large proportion of the diagnostic errors and lawsuits in cutaneous pathology. There is another group of cases in which the diagnosis of malignancy remains uncertain-these cases are especially problematic for both the pathologist and the treating clinician in that the diagnostic uncertainty may affect the recommended treatment and the need to advise the patient of the circumstances. The goal of this unique book is to provide detailed insight into a wealth of expert experience in such cases, with in-depth review of the expert's analysis and diagnostic process supported by high-quality color photomicrographs and discussion of the diagnostic principles involved in evaluating these lesions. Tumorigenic Melanocytic Proliferations is essential reading for surgical pathologists, dermatopathologists and dermatologists. In addition it will of interest to pathology residents and fellows, dermatology residents and dermatopathology fellows. About the Series: The Consultant Pathology series is designed to disseminate the knowledge of expert surgical pathology consultants in the analysis and diagnosis of difficult cases to the full community of pathology practitioners. The volumes are based on actual consultations and presented in a format that illustrates the expert's process of evaluating the case, including indications for consultation, the consultant's findings and comment, and discussion of the entity that amplifies the case description. Each volume in the Consultant Pathology series is authored by international experts with extensive case experience in the areas covered.
