Precision Measurements to Test the Standard Model and for Explosive Nuclear Astrophysics (Springer Theses)
by Adrian A. ValverdeThis thesis presents two significant results in the field of precision measurements in low-energy nuclear physics. Firstly, it presents a precise half-life determination of 11C, leading to the most precise ft-value for a beta decay transition between mirror nuclides, an important advance in the testing of the electroweak sector of the Standard Model. Secondly, it describes a high-precision mass measurement of 56Cu, a critical nucleus for determining the path of the astrophysical rapid-proton capture process, performed by the author using the LEBIT Penning trap at the National Superconducting Cyclotron Laboratory. This new measurement resolves discrepancies in previously-reported calculated mass excesses. In addition, the thesis also presents the construction and testing of a radio-frequency quadrupole cooler and buncher that will be part of the future N = 126 factory at Argonne National Laboratory aimed at producing nuclei of interest for the astrophysical rapid-neutron capture process for the first time.

Precision Metal Additive Manufacturing
by Richard Leach and Simone CarmignatoAdditive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design. Richard Leach is a professor in metrology at the University of Nottingham and heads up the Manufacturing Metrology Team. Prior to this position, he was at the National Physical Laboratory from 1990 to 2014. His primary love is instrument building, from concept to final installation, and his current interests are the dimensional measurement of precision and additive manufactured structures. His research themes include the measurement of surface topography, the development of methods for measuring 3D structures, the development of methods for controlling large surfaces to high resolution in industrial applications and the traceability of X-ray computed tomography. He is a leader of several professional societies and a visiting professor at Loughborough University and the Harbin Institute of Technology. Simone Carmignato is a professor in manufacturing engineering at the University of Padua. His main research activities are in the areas of precision manufacturing, dimensional metrology and industrial computed tomography. He is the author of books and hundreds of scientific papers, and he is an active member of leading technical and scientific societies. He has been chairman, organiser and keynote speaker for several international conferences, and received national and international awards, including the Taylor Medal from CIRP, the International Academy for Production Engineering.

Preclinical Evaluation of Antimicrobial Nanodrugs (Nanotechnology in the Life Sciences)
by Juan BuenoTranslational medicine addresses the gap between research and the clinical application of new discoveries. To efficiently deliver new drugs to care centers, a preclinical evaluation, both in vitro and in vivo, is required to ensure that the most active and least toxic compounds are selected as well as to predict clinical outcome. Antimicrobial nanomedicines have been shown to have higher specificity in their therapeutic targets and the ability to serve as adjuvants, increasing the effectiveness of pre-existing immune compounds. The design and development of new standardized protocols for evaluating antimicrobial nanomedicines is needed for both the industry and clinical laboratory. These protocols must aim to evaluate laboratory activity and present models of pharmacokinetic-pharmacodynamic and toxicokinetic behavior that predict absorption and distribution. Likewise, these protocols must follow a theranostics approach, be able to detect promising formulations, diagnose the infectious disease, and determine the correct treatment to implement a personalized therapeutic behavior. Given the possibilities that nanotechnology offers, not updating to new screening platforms is inadequate as it prevents the correct application of discoveries, increasing the effect of the valley of death between innovations and their use. This book is structured to discuss the fundamentals taken into account for the design of robust, reproducible and automatable evaluation platforms. These vital platforms should enable the discovery of new medicines with which to face antimicrobial resistance (RAM), one of the great problems of our time.

Predicting Flow-Induced Acoustics at Near-Stall Conditions in an Automotive Turbocharger Compressor
by Roberto Navarro GarcíaThis thesis offers new insights into the fluid flow behavior of automotive centrifugal compressors operating under near-stall conditions. Firstly it discusses the validation of three-dimensional computational fluid dynamics (CFD) unsteady simulations against acoustic experimental measurements using an original procedure based on plane wave pressure decomposition. It then examines the configuration of the CFD cases, highlighting the key parameters needed for a successful calculation. Moreover, it describes both the compressor mean and unsteady flow field from best-efficiency to near-surge operating points. Lastly, it provides readers with explanations of the various phenomena that arise when the mass flow rate is reduced and the compressor is driven to poor and noisy performance. Written for students, researchers and professionals who want to improve their understanding of the complex fluid flow behavior in centrifugal compressors, the thesis offers valuable practical insights into reducing the acoustic emissions of turbochargers.
Predicting Outcomes of Investments in Maintenance and Repair of Federal Facilities
by Committee on Predicting Outcomes of Investments in Maintenance Repair for Federal Facilities"Challenging. . . The real value of this book is in Mr. Hacker's calm, analytical eye, his unblinking view of American history and his unwillingness to accept cant and 'common sense' as facts. " --Tom Wicker The New York Times Book Review Why does race remain America's deepest and most enduring division? Despite all efforts to increase understanding and expand opportunities, black and white Americans still lead separate lives, continually marked by tension and hostility. In his bestselling analysis of a divided society, Andrew Hacker explains why racial disparities persist. He clarifies the meaning of racism, conflicting theories of superiority and equality, as well as such subtle factors as guilt and sexual fears. Using completely updated statistical data to paint the stark picture of racial inequality, Two Nations depicts the realities of family life, of income and employment, as well as current controversies affecting education, politics, and crime, including the role of race in the Simpson trial. This startling look at the facts that so many choose to ignore is balanced by the voices of African Americans, and shows how race influences the attitudes and behavior of all Americans. Reasoned, accurate, and devastating, Two Nations demonstrates, better than emotional appeals can, how this great and dividing issue has defined America's history and, as Hacker forecasts it, will play a pivotal role in the coming century. "Provocatively enlightening. . . Probably the most candid book on present day American racism to be written in the 20th century. " --Claude Brown Author of Manchild in the Promised Land "A telling portrait of American life. . . of the very different ways the two races live. . . The numbers are stark and irrefutable. " --The Wall Street Journal EXPANDED AND UPDATED EDITION -- Including a new chapter on the O. J. trial
