код для вставкиСкачатьThe volatile phytoncides (preferably called phytons, and generally known in the U.S.A. as “higher plant antibiotics”), which the higher plants produce for protection have, in addition to their protistocidal, bactericidal, and fungicidal properties, a growth promoting effect (callus and sprout formation). H . Scltildknecht and G . Rauclz succeeded in identifying the active material, isolated from Robinia pseurlrr- curia, as pure Az-hexenal. Likewise, they were able to trace the antibiotic effect of oak, alder, lupine, black currant, whortleberry, cranberry, and privet to A2-hexenal. Since in all investigated cases the antibiotic effect is due to the A2hexenal content, the theory that each leafy plant has its own specific antibiotic agent could not be proved. / 2.

This monograph is very well suited for self-study, as well as for advanced students and those engaged in the process industries; however it assumes a prior knowledge of introductory physics. Approximately 170 problems scattered throughout the text, with solutions given in a special appendix, facilitate selfinstruction. The book is recommended to anyone connected with the chemical process industries. The printing is good, as is the presentation of the illustrative material. However, not every interested student will be able to afford the book, and it should therefore be made available in instutional libraries. K. ffedden [BB 0055316 I E ] This long-needed textbook summarizes the physical principles underlying the chemical process industries. Using many examples and original comments, the author gives a masterful presentation of the physical laws and their quantitative applications. This book not only enables the student to become familiar with equations but, above all, provides him with a more profound insight into their functional relationship. The fundamental principles presented in the text will serve as a basis for mechanical and process engineers, chemists, physical chemists and physicists in the guidance of their technological work. The first three chapters deal with physical thermodynamics and kinetic phenomena. In the chapter “Mass and Energy Balances”, the author endeavors to give a clear definition of the quantities and units of measure entering into the formulation of energy balances. “The Concept and Application of Entropy” first increases the reader’s understanding of the second law of thermodynamics, and then further clarifies the concept of entropy with examples of application. Two examples of thermodynamic analysis, namely, evaporation of salt solutions and liquefaction of air, are particularly interesting. The “Probability Theory and Kinetic Theory of Gases” brings out, among other things, the general significance of statistics and the mathematics of probability in process technology. Problems in construction, of interest to the equipment designer, are found in chapter 4-“Strength of Materials”. The important field of materials with large surfaces per unit weight and of finely divided substances is treated in another chapter. More than half of the book deals with flow and transfer phenomena. The principles and applications of flow theory are presented in two sections, which are followed by a section treating “Dimensional Analysis and the Theory of Models”. Chapter 9 deals with the analogous momentum, heat and mass transfer phenomena which are related to irreversible thermodynamics. Multiphase flow phenomena, which are of great importance in many fields, are dealt with in chapter 10. Another section is concerned with rheological materials. In the “Summary”, the author endeavors, using a few examples, to present a generalized view point with the object of increasing the coherence of the large variety of material presented. The many references cited (the author index alone contains about 1200 entries) aid in locating the original literature Vitamins and Antivitamins, by A . Pongratz. Protoplasmatologia, Handbook of Protoplasm Research, edited by L. V. Heilbrunn and F. Weber. Vol. 11, B2bP: Published by Springer, Vienna (Austria) 1960. First edition. V, 98 pages. Paperbound DM 35.- (about $ 9.-). This book is a carelessly compiled collection of abstracts from the older vitamin literature up to about 1954, with only a few references to more recent publications, even though the book was not published until 1960. There is, however, a complete coverage of the author’s papers, even where they are of no great significance for the topic Although the title of the book includes the word “antivitamins”, terms like competitive and non-competitive inhibition are never mentioned. F. Moewus’ data o n the biological effects of isorhamnetin and its diglycoside are listed, although they have been disproved several years ago. There are some major errors to be found in the book; e . g . vitamin BIZi s described as a nucleic acid molecule; thioctic acid is suppbsed to carboxylate a-keto acids by oxidation; in P-vitamins, the 6-hydroxyl is alleged to form ethers with different sugars. T o characterize the style, I quote: “Chemical investigation of the structure was aided considerably by the typical form of the &-deficiency sickness in rats (86-RattenmangeIkrankheit)”, or “The reported results concerning the structure and physiological effects of the BIZ vitamins are based o n an unparalled system of logic”. After suffering through misprints, obsolete and illogical phrases, errors of fact, biased opinions, monstrosities in word and sentence construction, and much bad German, the reader comes to the following statement on the last page: “This magnificent wealth of ideas, brought about by the cooperation ofmanydisciplines, can be viewed with pride by all mankind”. In the opinion of this reviewer, such a statement certainly cannot be applied to the present book. R .
