Ancient Underground Opening and Preservation contains 59 papers presented at the International Symposium on Scientific Problems and Long-term Preservation of Largescale Ancient Underground Engineering (Longyou, China, 23-26 October 2015). The contributions focus on scientific and technical issues related to long-term preservation of large-scale anc

Ureases: Foundations, Classes, and Applications provides a thorough, practical analysis of ureases—enzymes of growing relevance across a range of biotechnological applications and drug discovery. Unique in many aspects, ureases are one of the few enzymes to have nickel in their active sites. Ureases covers all aspects of this enzymatic class. Starting with foundational overview, the book discusses historical urease research and the current state, from basic biochemistry to the use of ureases as hallmarks in enzymology, crystallography, and bioinorganic chemistry. The different classes of ureases, structurally diverse but chemically equivalent, are individually discussed. The multi-protein, multi-step activation of ureases (with chemical modification of residues, transport, and transfer of nickel ions) are examined in-depth, along with the catalytic mechanisms of ureolysis and its inhibitors. The final two sections of the book address multiple applications of ureases in health and biotechnology, respectively, going from gastric ulcer treatment to architectural uses in buildings and engineering. Future applications and next steps in research are also considered. - Considers fundamental aspects of urease biochemistry, ureolysis and urease inhibitors - Discusses urease research across a range of applications, from drug discovery to biosensors, water purification, architecture and the food industry - Features chapter contributions from international leaders in the field

The war on terrorism is not a new war, only the battlefront has changed. This war is a spiritual one that manifested when man fell to sin in the Garden of Eden. Enter Conner Mckenzie, a retired federal agent turned archeologist. After being forced into retirement due to anxiety issues, Conner sets out on a global quest to prove the existence of God using modern-day archeological evidence. His quest, however, brings his past life back, and Conner, along with his team of like-minded men, find themselves on the forefront of not only the war on terrorism but a war on Christianity itself. Traversing the globe, they follow recent archeological discoveries that could prove the physical existence of King David. Conner finds a hidden, sinister agenda in the war on terrorism that, if it succeeds, will change the face of Christianity on the planet forever.

The International Federation of Library Associations and Institutions (IFLA) is the leading international body representing the interests of library and information services and their users. It is the global voice of the information profession. The series IFLA Publications deals with many of the means through which libraries, information centres, and information professionals worldwide can formulate their goals, exert their influence as a group, protect their interests, and find solutions to global problems.

Did you know . . . • Ancient Romans invented a machine to harvest grain? • Farmers in ancient China destroyed the pests that harmed crops by bringing in their natural predators? • The ancient Mayans restored nutrients to the soil by planting corn and beans together? People learned to farm more than twelve thousand years ago. The first farmers used simple technology. They carried water to their crops by hand. They made farm tools from wood and animal bones. Over the centuries, ancient farmers devised better technology. Ancient Middle Easterners learned to breed sheep to produce different colors of wool. The ancient Chinese learned how to grow more rice using irrigation techniques. The ancient Greeks built machines for pumping water, grinding grain, and crushing grapes and olives. What kinds of crops did ancient farmers grow? What kind of animals did they raise? And how did people get their food before agriculture? Learn more in Ancient Agricultural Technology.

Often hidden away or incorporated into other architectural features, icehouses are a largely forgotten part of our heritage. As winters warmed through the nineteenth century, and supplies of natural ice declined, the development of artificial refrigeration made redundant these curious buildings – often status symbols in themselves – which had been designed to store winter snow and ice into the summer. Icehouses allowed perishables to be preserved, chilled delicacies to be enjoyed, and fevers to be relieved – and on a commercial scale they fed an international trade that carried snow from mountain peaks and ice from frozen lakes to supply the needs of industry, markets and householders. In this illustrated introduction, Tim Buxbaum explains how icehouses developed; how, when and where they were built; and how they operated, including a chapter on icehouses from around the world.

While cereals remain the world's largest food yield - with more than 2.3 billion metric tons produced annually - consumer demands are on the rise for healthier cereal products with greater nutrition. Cereal Grains: Properties, Processing, and Nutritional Attributes provides a complete exploration of the scientific principles related to domesticatio

All the traces of historic heritage are a fundamental part of our environment and reward us in the form of cultural enrichment, with the ability to have a positive effect both on our lifestyle and economy. Therefore, the preservation of ancient monuments, historic towns and sites has increasingly drawn the attention of public opinion, governmental
