Take a Detailed Look at the Practice of Drystone Retaining Wall Construction Drystone retaining walls make very efficient use of local materials, and sit comfortably in their environment. They make an important contribution to heritage and to the character of the landscape, and are loved by many people who value the skill and ingenuity that has gone into their construction, as well as simply how they look. And yet, in engineering terms, they are complex. They can deform significantly as their loading changes and their constituent stones weather. This gives them ductility—they deal with changes by adapting to them. In some ways, they behave like conventional concrete retaining walls, but in many ways they are better. They cannot be designed or assessed correctly unless these differences are understood. Implementing concepts that require no prior knowledge of civil engineering, the authors: Explain the behavior of earth retaining structures Provide a theoretical framework for modeling the mechanical stability of a drystone retaining wall Outline reliable rules for constructing a drystone retaining wall Include charts to support the preliminary sizing of drystone retaining walls Examine the relevance of drystone in terms of sustainability Describe more advanced methods of analysis Drystone Retaining Walls: Design, Construction and Assessment draws on theoretical work and full-scale practical testing to explain how these structures work, without presuming that the reader has received an engineering education. The book goes on to give enough detail to give the professional engineer confidence in the methods used in design and assessment, and insight into what matters most in the way in which drystone retaining walls are built. It shows how to design new or replacement drystone retaining walls that are efficient, sustainable, attractive, and in keeping with the character of the area where they are built, and demonstrates how to make fair assessments of existing walls.

This Dictionary of Fortifications is an attractive and convenient reference for anyone with an interest in castles, forts, walled cities and any other defensive architecture, including temporary structures, of any period. The heart of the book is a useful glossary of over 1,200 terms relating to fortifications through the ages. Drawn from many languages besides English, each has at least a concise definition or description, while more significant entries take the form of short articles. Many are accompanied by a clear sketch, diagram, cross-section, floor plan or map skillfully executed by the author himself. In all, there are over 400 of these black and white illustrations. Although the glossary is organized alphabetically (from Abatis to Zwischenwiderstandnet), cross references allow the reader to easily follow themes of interest through the book. Buttressing the glossary there is a section giving an overview of the historical development of fortifications from prehistory to the present day. A further chapter outlines the concomitant development of siege warfare over the same long span, detailing the evolution of siege engines and other tactics used to overcome fortifications. This is a fascinating reference for anyone with the slightest interest in military architecture.
During the Middle Ages, castles and other fortified buildings were a common feature of the European landscape. As central powers rose and fell, the insecurity of the times inspired a revival of fortifications first introduced in the Roman Empire. Despite limitations in construction techniques and manpower, medieval fortifications were continuously adapted to meet new political circumstances and weapons technology. Here is an illustrated guide to the architecture of medieval fortifications, from the first castles to the fortified cities of the 15th and 16th centuries. In hundreds of detailed and thoroughly researched pen-and-ink drawings, historian and artist Jean-Denis G. G. Lepage introduces the reader to the development and diversity of European medieval military architecture. Each drawing is accompanied by meticulous descriptions of types of buildings (e.g., motte-and-bailey castles), built-in defenses (arrow slits, pepper-pot towers), and particular castles and cities (the Mont-Saint-Michel, the city of Jerusalem). Elements of medieval warfare and weaponry are also covered in drawings and text.
As an applied science, enology is a collection of knowledge from the fundamental sciences including chemistry, biochemistry, microbiology, bioengineering, psychophysics, cognitive psychology, etc., and nourished by empirical observations. The approach used in the Handbook of Enology is thus the same. It aims to provide practitioners, winemakers, technicians and enology students with foundational knowledge and the most recent research results. This knowledge can be used to contribute to a better definition of the quality of grapes and wine, a greater understanding of chemical and microbiological parameters, with the aim of ensuring satisfactory fermentations and predicting the evolution of wines, an7thd better mastery of wine stabilization processes. As a result, the purpose of this publication is to guide readers in their thought processes with a view to preserving and optimizing the identity and taste of wine and its aging potential. This third English edition of The Handbook of Enology, is an enhanced translation from the 7h French 2017 edition, and is published in print as individual themed volumes and as a two-volume set, describing aspects of winemaking using a detailed, scientific approach. The authors, who are highly-respected enologists, examine winemaking processes, theorizing what constitutes a perfect technique and the proper combination of components necessary to produce a quality vintage. They also illustrate methodologies of common problems, revealing the mechanism behind the disorder, thus enabling a diagnosis and solution. Volume 1: The Microbiology of Wine and Vinifications addresses the first phase of winemaking to produce an "unfinished" wine: grading grape quality and maturation, yeast biology then adding it to the grape crush and monitoring its growth during vinification; and identifying and correcting undesired conditions, such as unbalanced lactic and acetic acid production, use of sulfur dioxide and alternatives, etc. Coverage includes: Wine microbiology; Yeasts; Yeast metabolism; The conditions for the development of yeasts; Lactic acid bacteria, their metabolism and their development in wine; Acetic bacteria; The use of sulfur dioxide in the treatment of musts and wines; Products and processes acting in addition to sulfur dioxide; Winemaking; The grape and its maturation; Harvesting and processing of grapes after harvest; Vinification in red and white wine making. The target audience includes advanced viticulture and enology students, professors and researchers, and practicing grape growers and vintners.

Roland Nair calls himself Scandinavian but travels on a U.S. passport. After ten years’ absence, he returns to Freetown, the capital of Sierra Leone, to reunite with his friend Michael Adriko. They once made a lot of money here during the country’s civil war, and, curious to see whether good luck will strike twice in the same place, Nair allows himself to be drawn back to a region he considers hopeless. Adriko is an African who styles himself a soldier of fortune and who claims to have served, at various times, the Ghanaian Army, the Kuwaiti Emiri Guard, and the American Green Berets. He’s probably broke now, but he remains, at thirty-six, as stirred by his own doubtful schemes as he was a decade ago. Although Nair believes some kind of money-making plan lies at the back of it all, Michael’s stated reason for inviting his friend to Freetown is that Nair should meet Michael’s fiancee, a college girl named Davidia from Colorado. Together the three set out to visit Michael’s clan in the Uganda-Congo borderland—but each of these travellers is keeping secrets from the others. Shadowed by Interpol, the Mossad, and MI-6, Nair gets mired in lust and betrayal in a landscape of frighteningly casual violence as he travels with Adriko and Davidia, gets smuggled into a war zone, kidnapped by the Congo Army, and terrorized by a self-proclaimed god ruling over a dying village. Their journey through a land abandoned by the future leads Adriko, Nair and Davidia to meet themselves not in a new light, but rather in a new darkness. A high-suspense tale of kaleidoscoping loyalties in the post-9/11 world, The Laughing Monsters shows one of our great novelists at the top of his game.
