Book Description
Lime is a white, powdery substance widely used in construction, agriculture, and industry. It is manufactured by heating limestone. Small amounts may be produced in an open fire but more effectively when enclosed. Early pits were lined with stone and in time enclosed in an oven or kiln. The 19th-century lime kiln, of Roman design, was a large "pot" dug into a hillside, surrounded by a stone box resembling a huge fireplace. Many thousands were built in the Susquehanna River valley. During settlement of "Penn's Woods," large tracts were subdivided many times, and by 1925 we find 12,000 farms in Lancaster County alone, and nearly every farmer wanted to produce his own lime to sweeten the fields and make mortar, plaster, and whitewash. In the most recent record, the 1875 county atlas, we find more than 500 kilns, a peak time for "do it yourself" lime burning. Commercialization relieved the farmer of the hard and dangerous work of lime burning, and the kilns fell idle around the turn of the century. Today we find evidence of 128 extant kilns in the county. Some are little more than remnants of former stonework, but others remain sturdy and sound. Their photos in this book reveal the art and labor of our ancestors who played a major role in the development of our nation.

Book Description
Waterford harbour has centuries of tradition based on its extensive fishery and maritime trade. Steeped in history, customs and an enviable spirit, it was there that Andrew Doherty was born and raised amongst a treasure chest of stories spun by the fishermen, sailors and their families. As an adult he began to research these accounts and, to his surprise, found many were based on fact. In this book, Doherty will take you on a fascinating journey along the harbour, introduce you to some of its most important sites and people, the area's history, and some of its most fantastic tales. Dreaded press gangs who raided whole communities for crew, the search for buried gold and a ship seized by pirates, the horror of a German bombing of the rural idyll during the Second World War – on every page of this incredible account you will learn something of the maritime community of Waterford Harbour.

Book Description
- Modern uses of traditional materials - 'Lime and Limestone' is a comprehensive and up-to-date presentation of the main scientific and technological aspects of the quarrying, processing, calcining and slaking of lime and limestone products. It places emphasis on how the processes are designed to ensure that the products meet market requirements and comply with customer specifications. It describes authoritatively, and in detail, the current uses in the many market segments, including: - iron, steel and other metals, - building, construction and cement, - water, sewage and environmental protection, - chemicals, agriculture and foodstuffs. It also addresses topical issues such as: environmental protection measures within the industry, toxicology, occupational health, storage, transportation, economic aspects, sampling, testing and analysis. The book maintains a good balance between scientific information - of use to technologists - and more general information - of value to production and commercial personnel, both within the lime and limestone industries and in the many industries that they serve.

Book Description
This book presents a state of the art in mortar characterisation, experimentation with and applications of new mortars for conservation and repair of historic buildings. This volume includes the following topics: characterisation of historic mortars (methods, interpretation, application of results), development of new materials for conservation (compatibility, durability, mix designs), the history of mortar technology and fundamental experimental studies of material properties. The papers have been selected from those presented at the 3rd Historic Mortars Conference, held in Glasgow, Scotland, September 11-14th 2013. All the papers here underwent a two stage peer review process, for the conference and again for this volume. In some cases this has resulted in a revision and updating of content.

Book Description
Rotary Kilns—rotating industrial drying ovens—are used for a wide variety of applications including processing raw minerals and feedstocks as well as heat-treating hazardous wastes. They are particularly critical in the manufacture of Portland cement. Their design and operation is critical to their efficient usage, which if done incorrectly can result in improperly treated materials and excessive, high fuel costs. This professional reference book will be the first comprehensive book in many years that treats all engineering aspects of rotary kilns, including a thorough grounding in the thermal and fluid principles involved in their operation, as well as how to properly design an engineering process that uses rotary kilns. This new edition contains an updated CFD section with inclusion of recent case studies and in line with recent developments covers pyrolysis processes, torrefaction of biomass, application of rotary kilns in C02 capture and information on using rotary kilns as incinerators for hydrocarbons. - Provides essential information on fluid flow, granular flow, mixing and segregation, and aerodynamics during turbulent mixing and recirculation - Gives guidance on which fuels to choose, including options such as natural gas versus coal-fired rotary kilns - Covers principles of combustion and flame control, heat transfer and heating and material balances - New edition contains information on pyrolysis processes with low temperatures and torrefaction of biomass. It also covers calcination of petcoke, how rotary kilns are used as incinerators for chlorinated hydrocarbons. - Includes updated material on CFD simulation of kiln gas and solids flow with a selection of recent case studies.

Book Description
Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.

Book Description
This work studies the historical transition from the agrarian solar energy regime to the use of fossil energy, which has fuelled the industrial transformation of the last 200 years. The author argues that the analysis of historical energy systems provides an explanation for the basic patterns of different social formations. It is the availability of free energy that defines the framework within which socio-metabolic processes can take place. This thesis explains why the industrial revolution started in Britain, where coal was readily available and firewood already depleted or difficult to transport, whereas Germany, with its huge forests next to rivers, was much longer dependent on a traditional solar energy regime."
