The agricultural world has changed significantly during the last years. The excessive use of heavy machinery, waste disposal, the use of agrochemicals and new soil cultivation means led to severe problems, which agricultural engineers have to cope with in order to prevent soil from permanent irreversible damage. This Soil Biology volume will update readers on several cutting-edge aspects of sustainable soil engineering including topics such as: soil compaction, soil density increases, soil disturbance and soil fragmentation; soil tillage machineries and optimization of tillage tools; soil traffic and traction, effects of heavy agricultural machines, the use of robotics in agriculture and controlled traffic farming; mechanical weed control, the characterization of soil variability and the recycling of compost and biosolids in agricultural soils.
This interdisciplinary handbook provides extensive information about research in medieval studies and its most important results over the last decades. The handbook is a reference work which enables the readers to quickly and purposely gain insight into the important research discussions and to inform themselves about the current status of research in the field. The handbook consists of four parts. The first, large section offers articles on all of the main disciplines and discussions of the field. The second section presents articles on the key concepts of modern medieval studies and the debates therein. The third section is a lexicon of the most important text genres of the Middle Ages.

The result is a reference work which exhaustively documents the current status of research in medieval studies and brings the disciplines and experts of the field together.
At first glance, roads seem like the simplest possible geotechnical structures. However, analysis of these structures runs up against complexities related to the intense stresses experienced by road surfaces, their intense interaction with climate, and the complicated behavior of the materials used in road construction. Modern mechanistic approaches to road design provide the tools capable of developing new technical solutions. However, use of these approaches requires deep understanding of the behavior of constituent materials and their interaction with water and heat which has recently been acquired thanks to advances in geotechnical engineering. The author comprehensively describes and ex...
A wealthy Swedish privateer in the service of the Dutch dies intestate in Guyana. Almost 300 years later the huge inheritance has still not been accounted for. Olof Högberg's famous history of the Lambert Inheritance, published in 1916, is now translated for the first time into English.
This two volume guide provides a comprehensive overview of the fundamental principles and guidelines for documenting cultural heritage places. It seeks to aid heritage managers and decision makers in understanding their roles and responsibilities inn this essential activity. Volume 1 (Guiding Principles) explains why heritage managers must make sure that heritage information fully integrated into all research, investigation and conservation activities. Through the discussion of basic principles, benefits and new approaches, it assists those in charge of preserving immovable cultural heritage by bringing current heritage information practices to a new level. By recording we create a reference...
