Buch. Zustand: Neu. Neuware - Origin and Aims of this essay It was not by choice but by the misfortunes or fortunes of the last war, that I became involved with rivers. In December 1946 I obtained a lecturing post at the then Gordon Memorial College at Khartoum and the Principal of the college brought me to confluence of the two Niles and urged me to 'do something' on the biology of the river. I was very reluctant, my experience was limited to lakes in Poland up to 1939, and I did not know anything about work on rivers. The 'equipment' was a rowing boat, hired, and a 'home made' plankton net. This limited our first exploratory steps to the immediate vicinity of Khartoum. In both the White and Blue Nile we discovered the presence of a pure plankton. This was contrary to opinions expressed in the limited scientific literature available at Khartoum which stimulated our doubts and the search for the origin of this phenomenon. And so, early in our work, we became aware of the longitudinal sequence of events in running water, a fundamental feature of river ecology. of work were daunting; In the Nile, as in other long rivers, the difficulties the water courses stretch for thousands of kilometers south and north of our base, our work had to be done in time free from lecturing duties, no research grants were available.

Buch. Zustand: Neu. Neuware - Recent advances in the field of high pressure techniques influenced me to propose an Advanced Study Institute in Hi0h Pressure Chemistry. It was intended that the summer school should devote itself exclusively to the description and discussion of the effects of pressure in chemistry. Besides typical effects on matter, the application of high pressure techniques to existing research methods were to be treated, as well as pressure effects on reaction rates and equilibria. According to the concept of the Advanced Study Institute Program, the Summer School proceedings were meant to be a high level teaching activity. It was emphasized that the contributions should have the character of surveys rather than of highly specialized reports on recent research results. NOw, following the successful completion of the summer school, which involved very close cooperation with my colleagues during its preparation, it is my sincere wish to thank all the lecturers and contributors to this volume for the extreme care they used in preparing the lectures and manuscripts. I am especially grateful to the members of the organizing committee for their valuable assistance. Finally, the financial support of the Scientific Affairs Division of the North Atlantic Treaty Organization is equally appreciated by participants and organizers of the Advanced Study Institute.

Buch. Zustand: Neu. Neuware - The 2nd International Symposium on Trichoptera was held at the University of Reading, England, 25-29 July 1977. It attracted 68 participants from 22 countries, which was a gratifying response to the circulation of about 250 workers on caddis flies. It was H. MALICKY who appreciated the need for a specialized meeting of this kind and organized the 1st International Symposium on Trichoptera, which was held at Lunz am See, Austria, 16-20 September 1974. This volume of Proceedings includes 38 papers; all except one were presented and discussed in the sessions listed in the programme. The papers were given in a lecture theatre of the Palmer Building, and demonstrations were laid out in a laboratory of the Department of Zoology where members met for their mprning and afternoon breaks. Members were accommodated in St Patrick's Hall, one of the University Halls of Residence. They were the guests of the University at an informal reception on 25 July. On the afternoon of 27 July an excursion was made to the River Lambourn at Bagnor near NeWbUry. This chalk stream has been the subject of an ecological study by a team from the Department of Zoology since 1970. The excursion was also an opportunity to see something of the local caddis fauna, and to do some collecting. The final session on 29 July, under the chairmanship of G. B. WIGGINS, was followed by a discussion on future plans.
