The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.
Chemical Synthesis of Hormones, Pheromones and Other Bioregulators

Год издания:
Many small molecules occur naturally as «messenger» chemicals which regulate the behaviour and functions of microbes, plants, insects and animals. Examples include hormones, pheromones, phytoalexins, and antifeedants. These biofunctional molecules are of great interest to researchers in helping develop our understanding of biological function and in the development of new drugs. However extracting them from nature can be prohibitively expensive, so there is great interest in devising methods of synthesising them from simple starting materials in the laboratory. Chemical Synthesis of Hormones, Pheromones and Other Bioregulators is an introduction to the techniques and strategies for the synthesis of biofunctional small molecules. Topics include: what are biofunctional molecules? why must biofunctional molecules be synthesized? how can we synthesize biofunctional molecules? the synthesis of phytohormones, phytoalexins and other biofunctional molecules of plant origin the synthesis of insect juvenile hormones and antifeedants the synthesis of pheromones and the significance of chirality in pheromone science the synthesis of microbial hormones and pheromones, antibiotics, and other biofunctional molecules of microbial origin the synthesis of marine antifeedants and medicinal candidates a synthetic examination of incorrectly proposed structures of biomolecules reflections on science as a human endeavor Drawing on a career of almost 50 years researching and teaching this subject, Kenji Mori's Chemical Synthesis of Hormones, Pheromones and Other Bioregulators is a must-have textbook for students and researchers of organic synthesis and natural products, and a stimulating and inspiring account of a distinguished chemical career.
Automatic Control Systems. New Concepts and Structures of Regulators

The present study explores the possibility of achieving a commensurate or better result by a simpler controller in comparison with the well-known sophisticated methods of synthesizing PI?D?-regulators. It is shown that these regulators are more complex than the well-known and successfully used PIDregulators. The possibility of achieving better results in an easier manner is demonstrated. The requirements for an ideal linear automatic control system in the form of an ideal amplitude-frequency characteristic are justified. The methods of designing such regulators are given and examples showing their advantage are presented. Criticism of nonanalytic methods for calculating controllers is also provided and the advantages of methods based on numerical optimization are justified. Also, the monograph discusses adaptive and selfadjusting systems from the new point of view. It gives modern classification based on modeling and analytical research. The monograph can be used as a textbook for full-time and part-time PhD- and Master-students in the fields of «Automation and Mechatronics» and «Control in Technical Systems».
