Vacuum Technology : Practice for Scientific Instruments
Nanotechnology has reached a level where almost every new development and even every new product uses features of nanoscopic properties of materials. As a consequence, an enormous amount of scientific instruments is used in order to synthesize and analyze new structures and materials. Due to the surface sensitivity of such materials, many of these instruments require ultrahigh vacuum that has to be provided under extreme conditions like very high voltages. In this book, Yoshimura provides a review of the UHV related development during the last decades. His very broad experience in the design enables him to present us this detailed reference. After a general description how to design UHV systems, he covers all important issue in detail, like pumps, outgasing, Gauges, and Electrodes for high voltages.
Vaccines, medicines and COVID-19 : How can WHO be given a stronger voice?
The considerable health, economic and social challenges that the world faced at the beginning of 2020 with COVID-19 continued and worsened in many parts of the world in the second-half of 2020 and into 2021. Many of these countries and nations wanted to explore COVID-19 on their own, sometimes without listening to the main international health bodies such as WHO, an agency of the United Nations system with long-standing experience and vast knowledge at the global level and of which all countries in the world are members.
Utilizing Sumac (Rhus coriaria) in pharmaceutical preparations for skin health
Aims to extract gelatin from sumac berries and incorporate it into two cosmetic products—a lip balm and a facial/hand mask—evaluating their physicochemical properties, antioxidant activity, and skinbenefiting attributes. A secondary objective is to assess the level of awareness among the Syrian population regarding sumac’s various uses beyond its culinary applications. Sumac fruits were mechanically ground and subjected to immersion, ultrasound, and microwave-assisted extraction methods, followed by filtration and evaporation to yield a viscous gelatinous extract.

It is the aim of this book to share views from experts from industry and academia who look a step ahead, providing their strategies and approaches for the future of user-friendly speech dialog systems.Contributions spotlight issues such as automatic user classification, uncovering users’ interaction schemes, speech interaction as part of multimodal user interfaces, relation of subjective and objective data, and the role of voice and style in designing a brand specific acoustic appearance
Urban Operating Systems : Producing the Computational City
A new wave of enthusiasm for smart cities, urban data, and the Internet of Things has created the impression that computation can solve almost any urban problem. Subjecting this claim to critical scrutiny, in this book, Andrés Luque-Ayala and Simon Marvin examine the cultural, historical, and contemporary contexts in which urban computational logics have emerged. They consider the rationalities and techniques that constitute emerging computational forms of urbanization, including work on digital urbanism, smart cities, and, more recently, platform urbanism. They explore the modest potentials and serious contradictions of reconfiguring urban life, city services, and urban-networked infrastructure through computational operating systems--an urban OS.
Urban Landscape Perspectives
Urban Landscape Perspectives explores how landscape terminology can be usefully brought into the urban debate. Articles in this book include theoretical reflections on the landscape as an eminently project-like figure. It argues for attention to be drawn to the landscape as the origin of the sense of man’s home and of the reasons for the city, as well as to the search for the primary elements of city construction, of its public sphere.
Unsteady Aerodynamics, Aeroacoustics and Aeroelasticity of Turbomachines
The papers represent the latest in state of the art research in the areas of aeroacoustics, aerothermodynamics, computational methods, experimental testing related to flow instabilities, flutter, forced response, multistage, and rotor-stator effects for turbomachinery.
Unifying Perspectives in Computational and Robot Vision
The field of computer vision has developed significantly over the last several years and the application areas span a broad range from medicine to robotics and surveillance. In robotics, computer vision is mainly seen as another sensory modality and new algorithms are commonly developed for different applications. In the computer vision community, there have been more requirements for benchmarking and comparison of methods but very few are still applied in realistic settings and in real-time which is one of the strongest requirements in robotic applications. Unifying Perspectives in Computational and Robot Vision brings the communities of robot and computer vision to a joint appreciation of the value of systems, where there is a need to consider all aspects from perception to action generation.I1222
Une introduction à la médecine traditionnelle chinoise ; Tome 1 : Le corps théorique = An introduction to traditional Chinese medicine ; Vol.1 : The theoretical body
Drawing directly from the primary sources, it illuminates the burgeoning of ideas within the medical community throughout its centuries of history, a development that might give the impression of a seemingly heterogeneous or even confused system of medicine. However, a patient study of the texts in light of the interpretations of the physicians reveals a different picture.

Understanding drugs markets : An analysis of medicines, regulations and pharmaceutical systems in the global south
Highlights the influence of the countries colonial and post-colonial history on their models for state regulation, production, and distribution, explores the determining role transnational actors as well as industries from the North but also and increasingly from the South play in influencing local pharmaceutical markets and looks at the behaviour of health care professionals and individuals. Stepping back, the authors then unpick the pharmaceuticalization process and the multiple regulations at stake by looking at the workings of, and linkages between, (biomedical health) pharmaceutical systems, (representatives of companies) industries, actors in private distribution, and consumer practices.

Uncertainty and Risk : Mental, Formal, Experimental Representations
This book tries to sort out the different meanings of uncertainty and to discover their foundations. It shows that uncertainty can be represented using various tools and mental guidelines. Some decision criteria are then related to each case and assessed. Alternative ways to deal with risk - and risk attitude concepts - are then examined in the above perspective. Behavior under uncertainty emerges from this book as something to base more on inquiry and reflection than on mere intuition.
Ultrasound of the Gastrointestinal Tract
