Download or read book Building Adaptation written by James Douglas and published by Routledge. This book was released on 2006-08-11 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: As existing buildings age, nearly half of all construction activity in Britain is related to maintenance, refurbishment and conversions. Building adaptation is an activity that continues to make a significant contribution to the workload of the construction industry. Given its importance to sustainable construction, the proportion of adaptation works in relation to new build is likely to remain substantial for the foreseeable future, especially in the developed parts of the world. Building Adaptation, Second Edition is intended as a primer on the physical changes that can affect older properties. It demonstrates the general principles, techniques, and processes needed when existing buildings must undergo alteration, conversion, extension, improvement, or refurbishment. The publication of the first edition of Building Adaptation reflected the upsurge in refurbishment work. The book quickly established itself as one of the core texts for building surveying students and others on undergraduate and postgraduate built environment courses. This new edition continues to provide a comprehensive introduction to all the key issues relating to the adaptation of buildings. It deals with any work to a building over and above maintenance to change its capacity, function or performance.

Download or read book An Enterprise Map of Ghana written by John Sutton and published by Hodder Christian Books. This book was released on 2012 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ghana's economy has grown rapidly over the past decade, and the goal of becoming a middle-income country in the fairly near future now seems attainable. The likely contribution of the oil sector makes the goal look all the more achievable. Yet this goal is unlikely to be attained without a substantial advance in Ghana's industrial capability. This is therefore a good moment to ask some questions. What are the current capabilities of Ghanaian firms? Where did those capabilities come from? Can the development of the oil sector lead to a parallel advance in related local industries? This volume presents the first general overview of Ghana's industrial sector. Each industry is profiled in detail, and the history and capabilities of leading firms are explored at length. ------------------ This is the second volume in John Sutton's "Enterprise Map" series, which profiles the industrial capabilities of selected countries in sub-Saharan Africa. The first volume was on Ethiopia and the forthcoming third volume will be on Tanzania. Further volumes in this series will appear in due course.

Available in PDF, EPUB and Kindle. Book excerpt: Both technically and economically, additives form a large and increasingly significant part of the polymer industry, both plastics and elastomers. Since the first edition of this book was published, there have been wide-ranging developments, covering chemistry and formulation of new and more efficient additive systems and the safer use of additives, both by processors in the factory and, in the wider field, as they affect the general public. This new edition follows the successful formula of its predecessor, it provides a comprehensive view of all types of additives, concentrating mainly on their technical aspects (chemistry/formulation, structure, function, main applications) with notes on the commercial background of each. The field has been expanded to include any substance that is added to a polymer to improve its use, so including reinforcing materials (such as glass fibre), carbon black and titanium dioxide. This is a book which has been planned for ease of use and the information is presented in a way which is appropriate to the users' needs.

Download or read book Principles and Applications of Modified Atmosphere Packaging of Foods written by B. Blakistone and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modified atmosphere packaging may be defined as an active packaging method in which an altered atmosphere is created in the headspace that retards chemical deterioration while simultaneously retarding growth of spoilage organisms. Shelf lives of perishable products, such as dairy products, meat, poultry, fish, fruits and vegetables, and bakery items are limited by biochemical changes in the product catalysed by exposure to the normal atmosphere (21 % oxygen, 78% nitrogen and less than 0. 1 % carbon dioxide) and growth of spoilage organisms. Modification of the atmosphere within a package containing these products helps to better maintain the quality of the food under longer storage conditions and retards the growth of undesirable organisms. Of course, deterioration is also slowed by chilling, which is required for the transport to market of highly perishable items like meat, poultry and fish that would either spoil or have the potential for contamination by certain food pathogens. Chilling plus a modification of the atmosphere optimizes the keeping quality of food. Modification of the atmosphere has been known for over a century as a means of food preservation and has become a very popular means of food preservation in the latter part of the 20th century. Modified atmosphere packaging (MAP) is practised extensively in Europe, Canada and the USo Both vacuum packaging (rem oval of air from the package) and addition of gases within the package are considered MAP.

Download or read book An Enterprise Map of Zambia written by John Sutton and published by . This book was released on 2013-04 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the first decade of the new millennium, Zambia's real GDP rose by 80%. Much of this rise came from the mining sector, but a substantial fraction came from the manufacturing sector, whose output rose by 50% in real terms over the decade. This volume provides a detailed account of Zambia's current industrial capabilities. From mining-related industries through general manufacturing, agribusiness and construction, it describes the structure of each of the country's major industries. It provides detailed profiles of fifty leading industrial companies that together represent the frontier of current capabilities in each area of activity. Along the way, it addresses key issues of current interest. Where did the capabilities of Zambia's leading industrial companies come from? How many of these companies came from abroad? How many had their origins in the public sector? And how many were set up by domestic trading companies that began local manufacturing operations? The copper industry generates three-quarters of Zambia's export earnings. But to what extent has Zambia developed downstream capabilities in the manufacture of copper products? How large a role is China playing in the flow of Foreign Direct Investment to Zambia? And in what industries are Chinese companies active? This is the fourth volume in John Sutton's "Enterprise Map" series, which profiles the industrial capabilities of selected countries in sub-Saharan Africa. Volumes on Ethiopia, Ghana and Tanzania have already appeared. The forthcoming fifth volume will be on Mozambique.
