Taschenbuch. Zustand: Neu. Neuware - This book covers our current understanding of the role of mesenchymal stem cells (MSCs) and other mesenchymal progenitors in skeletal regeneration, encompassing bone, cartilage and whole joint regeneration. The expansion reflects developments in the field to include data on the use of MSCs in drug development, growth factors, scaffolds and biomechanical manipulations for skeletal trauma and diseases, including osteoporosis and arthritis.Written for an audience of clinicians and young researchers who are exposed to MSCs in their work, this book summarizes recent findings pertaining to the definition and characterization of MSCs in skeletal tissues and discusses the mechanisms of their actions in regeneration of bone in vivo. The authors describe recent findings pertaining to the efficacy of MSC therapies in animal models and in human clinical trials and bring together literature showing that the ways MSCs are extracted, expanded and implanted can considerably affect bone formation outcomes. Finally, it presents the latest knowledge on the nature of native MSCs in skeletal tissues, which provide a platform for novel in situ tissue regeneration approaches for systemic bone disease such as osteoporosis.

Taschenbuch. Zustand: Neu. Neuware - As conventional oil resources are depleted worldwide, vast heavy oil reserves available in various parts of the world become increasingly important as a secure future energy source. Clear and rigorous, Heavy Oil Production Processes will prove useful for scientists and engineers already engaged in fossil fuel science and technology as well as scientists, non-scientists, engineers, and non-engineers who wish to gain a general overview or update of the science and technology of fossil fuels. Not only does the book discuss production processes but also provides methods that should reduce the environmental footprint and improve profitability.

Taschenbuch. Zustand: Neu. Neuware - Many people think of the Smart Grid as a power distribution group built on advanced smart metering¿but that's just one aspect of a much larger and more complex system. The 'Smart Grid' requires new technologies throughout energy generation, transmission and distribution, and even the homes and businesses being served by the grid. This also represents new information paths between these new systems and services, all of which represents risk, requiring a more thorough approach to where and how cyber security controls are implemented.This insight provides a detailed architecture of the entire Smart Grid, with recommended cyber security measures for everything from the supply chain to the consumer.

Buch. Zustand: Neu. Neuware - Mixed oxides are the most widely used catalyst materials for industrial catalytic processes. The principal objective of this book is to describe systematically the mixed oxide catalysts, from their fundamentals through their practical applications. After describing concisely general items concerning mixed oxide and mixed oxide catalysts, two important mixed oxide catalyst materials, namely heteropolyacids and perovskites, are taken as typical examples and discussed in detail.These two materials have several advantages: 1. They are, respectively, typical examples of salts of oxoacids and double oxide--that is, the two main categories of mixed oxides in solid-state chemistry. 2. Both exhibit excellent catalytic performance in nearly crystalline state and are used in several industrial applications. 3. They have been studied for many years.In addition, metal oxides functioning as a catalyst support (carrier) are included. Although the supports are very important in practical applications, and tremendous progress has been made in the past decades, few systematic reviews exist. It is notable that heteropolyacids and perovskite exhibit unique performance when used as a support.Fundamental catalytic science and technology and solid-state chemistry necessary are presented for the proper understanding of mixed oxide catalysts as well as for R&D. For the latter, the concept of design of practical catalysts is very important. This is considered throughout the book.
