In today’s society the issue of security has become a crucial one. This volume brings together contributions on the use of knowledge-based technology in security applications by the world’s leading researchers in the field.
This volume looks at the impact that different cropping systems and tillage have on soil’s biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions. The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers. The chapters address fundamental questions relevant to t...
The view of organic synthesis as "a concentrated expression of predictive ability and creative capacity" was advocated in the early 1950s. A concise and readable account of the role of synthesis in modern science, Organic Synthesis: The Science Behind the Art presents the general ideology of pursuits in the area of organic synthesis, and examines the methodologies that have evolved in the search for solutions to synthetic problems. This unique book details outstanding achievements of modern organic synthesis, not only for their scientific merits, but also for the aesthetic appeal of the target molecules chosen and the intrinsic beauty of the solutions to the problems posed. By judicious sele...

"Nothing of the former world holds true anymore," Zofia Nalkowska wrote in her Wartime Diaries on 7 May 1943. "Nothing has remained." The burning of the Warsaw ghetto had broken Nalkowska's privileged life in two; in the years to come, the need to bear witness to the horrors she had seen firsthand would lead this gifted member of the Polish avant-garde to write the stories in Medallions.
DARWIN’S THEORY OF EVOLUTION ranks among the most influential of modern scientific theories. Applying the methodology of COGNITIVE SEMANTICS , this study investigates how metaphors based on domains of JOURNEY, STRUGGLE, TREE and HUMAN AGENCY serve to conceptualize key concepts of Darwin’s theory — such as evolutionary change, natural selection, and relationships among organisms. At the outset the author identifies original metaphors in The Origin of Species, to turn to their realizations in modern discourse on evolution in later chapters. Thus, the study uncovers how metaphors contribute to structuring the theory by expressing it in a coherent and attractive way, and how they provide mental tools for reasoning. As the first comprehensive study of conceptual metaphors that underlie Darwin’s theory and affect the way we talk and think about evolution, it may be of interest not only to linguists and evolutionary biologists but also to anyone interested in the interconnection between thought and language.
