Phase Transformation in Metals
This textbook explains the physics of phase transformation and associated constraints from a metallurgical or materials science point of view, based on many topics including crystallography, mass transport by diffusion, thermodynamics, heat transfer and related temperature gradients, thermal deformation, and even fracture mechanics. The work presented emphasizes solidification and related analytical models based on heat transfer. This corresponds with the most fundamental physical event of continuous evolution of latent heat of fusion for directional or non-directional liquid-to-solid phase transformation at a specific interface with a certain geometrical shape, such as planar or curved front. Dr. Perez introduces mathematical and engineering approximation schemes for describing the phase transformation, mainly during solidification of pure metals and alloys. Giving clear definitions and explanations of theoretical concepts and full detail of derivation of formulae, this interdisciplinary volume is ideal for graduate and upper-level undergraduate students in applied science, and professionals in the metal making and surface reconstruction industries.

Structural Health Monitoring Damage Detection Systems for Aerospace
This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http: //odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.

It focuses on emissions of chemical compounds during the preparation and formation of molding sands, molds pouring with molten metal, molds cooling and castings knocking out. It also addresses the effects of the spent molding sands reclamation process and the influence of spent sands on the environment during their storage. Establishing the most sustainable techniques for limiting the negative impact of foundry processes on the environment is explored in detail. The book will be valuableto academics and industry professionals alike.Describes the mechanisms of hardening and thermal destruction of individual binders in moulding and core sands;Assesses the influence of moulding and core sands technology on the environment;Discusses state of the art moulding and core sand technology.
Her Cold War
While Rosie the Riveter had fewer paid employment options after being told to cede her job to returning World War II veterans, her sisters and daughters found new work opportunities in national defense. The 1948 Women's Armed Services Integration Act created permanent military positions for women with the promise of equal pay. Her Cold War follows the experiences of women in the military from the passage of the Act to the early 1980s.In the late 1940s, defense officials structured women's military roles on the basis of perceived gender differences. Classified as noncombatants, servicewomen filled roles that they might hold in civilian life, such as secretarial or medical support positions. Defense officials also prohibited pregnant women and mothers from remaining in the military and encouraged many women to leave upon marriage. Before civilian feminists took up similar issues in the 1970s, many servicewomen called for a broader definition of equality free of gender-based service restrictions. Tanya L. Roth shows us that the battles these servicewomen fought for equality paved the way for women in combat, a prerequisite for promotion to many leadership positions, and opened opportunities for other servicepeople, including those with disabilities, LGBT and gender nonconforming people, noncitizens, and more.
Biodiversity of Marine Microbes
The book entitled "Biodiversity of Marine Microbes" aims at highlighting the significance of marine microbes as primary producers, their contribution in complex ecological processes and their roles in biogeochemical cycles and ecosystem functioning. The book includes five research papers covering the diversity and composition of marine microbial communities representing all three domains of life in various marine environments, including coastal eutrophic areas, ice waters, and lagoons. One paper examines the diversity and succession of bacterial and archaeal communities from coastal waters in mesocosm experiments. The combination of classical tools with novel technological advances implemented in the methods of the papers offered an opportunity to answer fundamental questions and shed light on the complex and diverse life of marine microbes
Advances in Structural Mechanics Modeled with FEM
It is well known that many structural and physical problems cannot be solved by analytical approaches. These problems require the development of numerical methods to get approximate but accurate solutions. The minite element method (FEM) represents one of the most typical methodologies that can be used to achieve this aim, due to its simple implementation, easy adaptability, and very good accuracy. For these reasons, the FEM is a widespread technique which is employed in many engineering fields, such as civil, mechanical, and aerospace engineering. The large-scale deployment of powerful computers and the consequent recent improvement of the computational resources have provided the tools to develop numerical approaches that are able to solve more complex structural systems characterized by peculiar mechanical configurations. Laminated or multi-phase composites, structures made of innovative materials, and nanostructures are just some examples of applications that are commonly and accurately solved by the FEM. Analogously, the same numerical approaches can be employed to validate the results of experimental tests. The main aim of this Special Issue is to collect numerical investigations focused on the use of the finite element method
International Environmental Labelling Vol.7 DIY
This book is dedicated to the subject of environmental labels. The basis for the classification of its parts goes back to the types of environmental labelling according to the classification provided by the International Organization for Standardization. The idea of compiling this book came to the author's mind when it was observed that national environmental labelling models had been developed in most countries. This is, however, not the case everywhere; in many other countries, even the initial steps have not been taken.

100 Years of Ferroelectricity 1921-2021
Since the discovery in 1921 of ferroelectric properties in Rochelle salt by Valasek, no new ferroelectric material was found until Busch and Scherrer in Switzerland in 1935 discovered ferroelectricity in Potassium dihydrogen phosphate (KDP). However, during the Second World War, researchers in the US in 1943 discovered ferroelectric materials such as BaTiO3 having ferroelectric properties well above room temperature, that led to an explosion of research after the war in Western and Central Europe, Russia, and Japan, because of their promising and potential applications.This book gives an overview of relevant experimental and theoretical work in ferroelectricity. It is organized into three Sections, corresponding to three time periods. The first (1921-1960) includes early work by Valasek, works by Busch and Scherrer, Mason and Mattias, Shirane and Takeda, ending with theoretical work by Cochran on crystal stability and the soft mode theory of ferroelectricity. The second one (1961-2002) includes a number of experimental and theoretical publications on ferroelectric materials and ferroelectric transitions. The number of international meetings began to increase, and the number of papers increased exponentially. New subfields at that time included ferroelectric liquid crystals, thin films, dipolar glasses and relaxors.The last and final section (2002-2021) includes more recent publications on fundamental structural studies, neutron diffraction work on PZT, quantum tunneling and zero-point energy in ferroelectrics, investigations on the anomalous temperature dependence behavior of liquid water and other recent developments.The book will be a useful compendium on ferroelectrics for materials scientists, and/or PhD graduate students on ferroelectrics all around the world.

Deep Energy Retrofit
This book provides detailed information on how to set up Deep Energy Retrofits (DERs) in public buildings, and shares in-depth insights into the current status of the major technologies, strategies and best practice examples of how to cost-effectively combine them. Case studies from the U.S.A. and Europe show that that Deep Energy Retrofit can be achieved with a limited core technologies bundle readily available on the market. Characteristics of some of these core technology measures depend on the technologies available on an individual nation's market, on the minimum requirements of national standards, and on economics (as determined by a life cycle cost analysis). Also, requirements to building envelope-related technologies (e.g., insulation levels, windows, vapor and water barriers, and requirements for building airtightness) depend on specific climate conditions. This Guide provides best practice examples of how to apply these technologies in different construction situations.High levels of energy use reduction using core technology bundles along with improvements in indoor climate and thermal comfort can be only achieved when a Deep Energy Retrofit adopts a quality assurance process. In addition to design, construction, commissioning, and post-occupancy phases of the quality assurance process, the Guide emphasizes the importance of clearly and concisely formulating and documenting the Owner's goals, expectations, and requirements for the renovated building during development of the statement of work. Another important component of the quality assurance process is a procurement phase, during which bidders' qualifications, their understanding of the scope of work and its requirements, and their previous experience are analyzed.The building sector holds the potential for tremendous improvements in terms of energy efficiency and reducing carbon emissions, and energy retrofits to the existing building stock represent a significant opportunity inthe transition to a low-carbon future. Moreover, investing in highly efficient building materials and systems can replace long-term energy imports, contribute to cost cutting, and create a wealth of new jobs. Yet, while the technologies needed in order to improve energy efficiency are readily available, significant progress has not yet been made, and "best practices" for implementing building technologies and renewable energy sources are still relegated to small "niche" applications.Offering essential information on Deep Energy Retrofits, the book offers a valuable asset for architects, public authorities, project developers, and engineers alike.
