Spacesuits are essential for astronauts to survive and work in the harsh environment of space. They provide a pressurized environment, protection from radiation and micrometeoroids, and a means for temperature control. HVAC systems for space suits are one of the most critical components of these life-saving garments. They must be able to keep astronauts cool in direct sunlight and warm in the cold temperatures of space. They must also be reliable and lightweight, as every ounce of weight counts in space. This book provides a comprehensive overview of HVAC systems for space suits. It covers the design, development, testing, and operation of these systems. It also discusses the latest technologies and trends in spacesuit HVAC. This book is intended for a variety of audiences, including engineers, scientists, and students who are interested in the design and development of spacesuits and other life support systems. It is also a valuable resource for astronauts and other space professionals who need to understand the operation and maintenance of spacesuit HVAC systems. I hope that this book will help to advance the development of spacesuit HVAC systems and make space exploration safer and more comfortable for astronauts.
Polymeric Foams Structure–Property–Performance: A Design Guide is a response to the design challenges faced by engineers in a growing market with evolving standards, new regulations, and an ever-increasing variety of application types for polymeric foam. Bernard Obi, an author with wide experience in testing, characterizing, and applying polymer foams, approaches this emerging complexity with a practical design methodology that focuses on understanding the relationship between structure–properties of polymeric foams and their performance attributes. The book not only introduces the fundamentals of polymer and foam science and engineering, but also goes more in-depth, covering foam processing, properties, and uses for a variety of applications. By connecting the diverse technologies of polymer science to those from foam science, and by linking both micro- and macrostructure–property relationships to key performance attributes, the book gives engineers the information required to solve pressing design problems involving the use of polymeric foams and to optimize foam performance. With a focus on applications in the automotive and transportation industries, as well as uses of foams in structural composites for lightweight applications, the author provides numerous case studies and design examples of real-life industrial problems from various industries and their solutions. Provides the science and engineering fundamentals relevant for solving polymer foam application problems Offers an exceptionally practical methodology to tackle the increasing complexity of real-world design challenges faced by engineers working with foams Discusses numerous case studies and design examples, with a focus on automotive and transportation Utilizes a practical design methodology focused on understanding the relationship between structure-properties of polymeric foams and their performance attributes

The scale of ecological crises made us realize that every kind of politics has always been cosmopolitics, politics of a cosmos. Cosmos embraces everything, including the multifarious natural and material entities that make humans act. The book examines cosmopolitics in its relation to design practice. Abandoning the modernist idea of nature as being external to the human experience - a nature that can be mastered by engineers and scientists from outside, the cosmpolitical thinking offers designers to embark in an active process of manipulating and reworking nature ’from within.’ To engage in cosmopolitics, this book argues, means to redesign, create, instigate, and compose every single feature of our common experience. In the light of this new understanding of nature, we set the questions: What is the role of design if nature is no longer salient enough to provide a background for human activities? How can we foster designers’ own force and make present what causes designers to think, feel, and act? How do designers make explicit the connection of humans to a variety of entities with different ontology: rivers, species, particles, materials and forces? How do they redefine political order by bringing together stars, prions and people? In effect, how should we understand design practice in its relation to the material and the living world? In this volume, anthropologists, science studies scholars, political scientists and sociologists rethink together the meaning of cosmopolitics for design. At the same time designers, architects and artists engage with the cosmopolitical question in trying to imagine the future of architectural and urban design. The book contains original empirical chapters and a number of revealing interviews with artists and designers whose practices set examples of ’cosmopolitically correct design’.
Following his successful mission to recover the missing warship ESS Crimson, Captain John Duggan finds himself unredeemed in the eyes of his superiors. His duties resume and this time he’s given something easy - escort a cargo ship to a distant planet and bring it home safely. But war is never so predictable and a straightforward mission becomes something much more important. The outcome may well determine the future of humanity. Someone has terrible plans for the ESS Crimson and Duggan is about to find himself party to endless destruction. Even as worlds die, a new threat is waiting on the horizon. Bane of Worlds is a universe-spanning sci-fi adventure, which continues the Survival Wars series.
Welcome to the world of HVAC hydronic systems, where the marriage of heating, ventilation, and air conditioning meets the elegance and efficiency of water-based heating and cooling solutions. This book is an exploration of the principles, design, and applications of hydronic systems in the context of HVAC. As the demand for energy-efficient and environmentally friendly solutions continues to grow, hydronic systems have emerged as a preferred choice for heating and cooling residential, commercial, and industrial spaces. These systems leverage the unique properties of water as a medium for transferring thermal energy, offering numerous advantages over traditional air-based HVAC systems. The aim of this book is to provide a comprehensive and accessible resource for understanding the fundamentals of hydronic systems, their components, and their integration into building infrastructure. Whether you are a seasoned HVAC professional seeking to expand your knowledge or a student entering the field, this book will serve as a valuable guide. In the chapters that follow, we will delve into the key principles underlying hydronic systems, exploring topics such as fluid dynamics, heat transfer, system components, control strategies, and system design considerations. We will discuss various types of hydronic heating and cooling systems, including radiant floor heating, chilled beam systems, and fan coil units, highlighting their unique features and applications. Additionally, we will examine the role of pumps, boilers, heat exchangers, valves, and other essential components in hydronic systems. We will explore the intricacies of system balancing, zoning, and control, emphasizing the importance of proper installation, operation, and maintenance practices to ensure optimal system performance and energy efficiency. Throughout this book, we will also address emerging trends and technologies in the field of HVAC hydronic systems, such as advanced control algorithms, renewable energy integration, and smart building automation. By staying informed about these developments, you will be equipped to navigate the evolving landscape of HVAC engineering. It is my hope that this book will serve as a source of inspiration, knowledge, and practical guidance for those involved in the design, installation, and operation of HVAC hydronic systems.
