Advances in Molecular Breeding Toward Drought and Salt Tolerant Crops
Advances in Molecular Breeding toward Drought and Salt Tolerant Crops seeks to integrate the most recent findings about key biological determinants of plant stress tolerance with modern crop improvement strategies. This volume is unique because is provides exceptionally wide coverage of current knowledge and expertise being applied in drought and salt tolerance research, spanning the scientific hierarchy from physiology, biochemistry, development, and genetics, to the newest technologies being used to manipulate drought and salinity associated traits for germplasm improvement. This book will be an invaluable reference for educators and researchers in agronomy and horticulture, crop breeding, molecular genetics, and biotechnology.
Abstraction, refinement and proof for probabilistic systems
Probabilistic techniques are increasingly being employed in computer programs and systems because they can increase efficiency in sequential algorithms, enable otherwise nonfunctional distribution applications, and allow quantification of risk and safety in general. This makes operational models of how they work, and logics for reasoning about them, extremely important. Abstraction, Refinement and Proof for Probabilistic Systems presents a rigorous approach to modeling and reasoning about computer systems that incorporate probability. Its foundations lie in traditional Boolean sequential-program logic—but its extension to numeric rather than merely true-or-false judgments takes it much further, into areas such as randomized algorithms, fault tolerance, and, in distributed systems, almost-certain symmetry breaking. The presentation begins with the familiar "assertional" style of program development and continues with increasing specialization: Part I treats probabilistic program logic, including many examples and case studies; Part II sets out the detailed semantics; and Part III applies the approach to advanced material on temporal calculi and two-player games.
Abiotic Stress Tolerance in Plants : Toward the Improvement of Global Environment and Food
Stresses in plants caused by salt, drought, temperature, oxygen, and toxic compounds are the principal reason for reduction in crop yield. For example, high salinity in soils accounts for large decline in the yield of a wide variety of crops world over; ~1000 million ha of land is affected by soil salinity. Increased sunlight leads to the generation of reactive oxygen species, which damage the plant cells. The threat of global environment change makes it increasingly demanding to generate crop plants that could withstand such harsh conditions. Much progress has been made in the identification and characterization of the mechanisms that allow plants to tolerate abiotic stresses.
A Rosicrucian Utopia in Eighteenth-Century Russia : The Masonic Circle of N.I. Novikov
The author undertakes an investigation into the history of Russian Freemasonry that has not been attempted previously. Her premise is that the Russian Enlightenment shows peculiar features, which prevent the application of the interpretative framework commonly used for the history of western thought. The author deals with the development of early Russian masonry, the formation of the Novikov circle in Moscow, the ‘programme’ of Rosicrucianism and the character of its Russian variant and, finally, the clash between the Rosicrucians and the State. The author concludes that the defenders of the Ancien Régime were not wrong. In fact the democratic behaviour, the critical attitude, the practice of participation, the freedom of thought, the tolerance for the diversity, the search for a direct communication with the divinity.
