Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I With the immense success of modem science it has generally become accepted that the only way to acquire knowledge is by the use of the method uniformly practiced by working scientists. Consequently, the credibility of the claims of religion, which seem to be based on belief in revelation, tradition, authority and the like, have been considerably shaken. In the face of the serious threat provided by the ascendancy of modem scientific method ology, religious thinkers have adopted various defensive attitudes. Some have retreated into an extreme position where Theism is completely safe from any attack on it by the use of empirical methods of inquiry, maintaining that contrary to appearances, religion makes no factual claims whatsoever. To be religious, they say, is to subscribe to a certain value system; it is to adopt a set of practices and a given attitude to the meaning and purpose of life without making any assertions about this or that empirical feature of the universe. Others wishing to remain more faithful to what religion traditionally meant throughout the ages, agree that Theism does make factual claims but that these are so radically different from the kind of claims made by science that it is only right that they should be established by a separate method on its own. In matters of faith reliance on widely entrenched tradition and sacred authority is not objectionable according to some. 212 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume constitutes the proceedings of the~ymposium: 'Measur ing Selection in Natural Populations', held in memory of late professor Ove Frydenberg. The Symposium took place in Sandbjerg Manor House in Southern Jutland May 10-14, 1976. The purpose of the symposium was to reflect contemporary research on the mechanisms of biological evolu tion. The arrangement of the symposium was possible only with the assis tance and work of many other people. Professor Ole Barndorff-Nielsen took an active part in the planning and arrangement of the symposium. Our gratitude is also due to Ellen Christensen, Jens Ole Frier, Arno Jensen, Preben Jensen and Anne Nissen, all of whom took care of the practical arrangements at the symposium. The publication was prepared with the assistance of Arno Jensen, Preben Jensen, Verner Blak Nielsen and Kirsten Svendsen. The Symposium was financed by grants from The Danish Natural Science Research Council, The Danish Atomic Energy Commission and The University of Aarhus. Aarhus, June 1977 Freddy B.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From the point of view of individual consumer there are too many scientific papers being produced and published every year, too many to be looked up in the tremendous and steadi Iy increasing number and volume of scientific periodicals and proceedings from allover the world. This is not only the result of the 'publish or perish' law, but also - let us hope mainly - the result of the increasing amount of true scientific information discovered. Even in a single scientific field too many papers are to be preselected according to the individual interest and to be looked through in order to see what they are reporting on. [And of course they are too many in these preselected to be read and studied in detai I. At the present nobody wi I I help us with this last link of what is called the information chain. But let us not speak about this lamentable point now. l Some tools are already wei I known and have been used to master more easily the overwhelming flood of scientific production as far as the first selection of information is concerned. Bibl iographies covering specific fields are one of these tools. They extremely faci I itate the preselection and when carefully indexed they give the user much more than a heap of selected titles. Such a periodiC bibliography in the field of plant-water relations is sti I I lacking. 100 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book really ought to be read on vacation, just for enjoyment. Granted, cancer is, literally, a deadly serious matter, and cancer research is primarily a part of medicine with Hippocrates in its back ground. Yet, cancer research is also natural science, and as such it yields the joys and sorrows of any science. The cancer problem is also a brain teaser, a challenge for the curious. This introductory report on experimental cancer research is there fore directed to curious students of many disciplines: naturally to medical students, but also to chemists and physicists who have an interest in biological phenomena; biology students will surely en counter pr9blems peculiar to their field in what is supposedly a medi cal one. We have attempted to write without assumptions to a certain degree, for a chemist is essentially in over his head in medicine, and a physician has only the slightest idea of the chemical problems im portant in cancer research. We had no intention of giving a complete view of the field, and from the large number of different lines of development we have chosen only a few. Chemotherapy, as an ex ample, has been treated quite cursorily, along with RNA tumor viruses, although it is possible that just these subjects are especially important for human tumors. Tumor induction via radiation could only be mentioned in passing, in spite of its great practical significance; similarly the role of hormones was only intimated. 312 pp. Englisch.…

The third part is an introduction to Brauer Theory. 200 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -It has become a tradition in the Union to publish the Invited Discourses and the Proceedings of the Joint Discussions held at a Gene ral Assembly in a separate volume entitled HIGHLIGHTS OF ASTRONOMY. This is the fourth volume of its kind and it contains some of the scientific highlights of the Grenoble General Assembly. In order to reduce its size it was decided to publish its content in two separate parts. The part (I) contains the full texts of the In vited Discourses given by Prof. J.-C. Pecker and by Dr. C. Sagan, and an abstract of Dr. P. Morrison's paper, thus complying with his wish to forego publication of the full text of his Discourse. Furthermore it collects the proceedings of three Joint Discussions and one Joint Meeting all of which are related essentially to observations from space, to external galaxies and to cosmology. Part (n) contains the proceedings of the four Joint Discussions and one Joint Meeting related essentially to stars and the structure of our Galaxy. Clearly Volume 4 (parts I and TI) of the Highlights reflects only a part of the scientific activities which took place at the Grenoble General Assembly. Many more important papers and discussions were held during Commission meetings and joint meetings. They may be found in the Commissions' reports published in the Transactions Vol. XVI B, 1977. 380 pp. Englisch. …

It com prises e. g. such models like cash balance models, production smoothing models and pure inventory models. We shall here mainly be concerned with stochastic dynamic problems and shall give exact definitions in the next section. Most of our work will concentrate on cash balance models. However, production smoothing situations and pure inventory problems will also be investigated. Since we are faced in principle with dynamic stochastic situa tions a dynamic programming approach would be appropriate. This approach, however, due to computational restraints, is limited to only but the simplest models. Therefore, in practice, one ruduces stochastics just in taking forecasts of demand and then treating the problem as a deterministic optimization problem. In addition one often introduces certain safety stocks to safeguard the system from possible forecasting errors. In general, this proce dure is suboptimal. However, there exists one particular situa tion when a separation in a forecasting procedure and a subse quent optimization of the remaining deterministic model is not suboptimal. This is known as the linear-quadratic model, i. e. a model having linear system equations and a quadratic cost crite rion. For this type of model H. A. Simon ~3J and later H. Theil [25J have shown that the above separation property holds. In fact, Simon's and Theil's results are nothing else but what has later and more generally become known to control engineers as Kalman's famous separation principle.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 128 pp. Englisch.…
