摘要:

The report of the Committee on Snow consists of a survey of current activities dealing with research on snow compiled by members of the Committee in correspondence with workers listed below. The character of the reports and the comprehensiveness of the subjects attest to the virility of research on snow.

摘要:

The members have cooperated splendidly in advancing the objectives of the Committee which are to suggest, stimulate, coordinate, and report on research in precipitation. They have reported several research investigations, reports on some of which will be presented in subsequent issues of theTransactionsand at future annual meetings. Kittredge of the University of California reports a study on the influence of forests on snow. This deals with the density of freshly fallen snow in the open and under the crowns of trees. A relation has also been established between the water equivalent of snow intercepted by the crowns and the amount of precipitation per storm.

摘要:

The author has given an interesting and enlightening account of the difficulties met in keeping accurate levels on a site which is being used for construction operations. He and his assistants are to be congratulated on the patience and ingenuity they showed in carrying their job to a successful conclusion.From the nature of the work described in the paper, it is evident that the expense involved was by no means negligible. The author was fortunate that in this case the size and public importance of the White House project ensured that the necessary funds were provided, once the need for keeping accurate level records was recognized. On less important construction jobs, the cost such a task is often a stumbling block, even when the resulting records might be considered an essential part of good construction practice. Certainly the obstacles reported in the paper are not encouraging to anyone planning similar work with limited funds at his disposal.

摘要:

The suggestion of an effect on monthly rainfall totals as a result of cloud seeding is based on deviation to the right of the regression line. However, as Krick and Smith point out, the deviation may even be great under natural conditions. In all but two of the seven evaluations, greater deviations than for the month of seeding has occurred in past years. Obviously, more years of seeding must be added to the record before an effect can be claimed. If the seeding has been successfully restricted to the target area in Oregon and is effective, an area immediately to the north and one to the south must have experienced relatively less rainfall.This follows from the fact that the moisture‐laden air flows strongly from the west. Accordingly, Figures 8, 9, and 10 were constructed to show this relationship. The control stations were related by simple arithmetic average (the alternative method mentioned by Krick and Smith) to similar averages for the three areas to the eas

摘要:

In their preface the authors say, “Nuclear physics is by no means a finished edifice. It is very much to be hoped that the fundamental laws can be discovered which will account for all the known properties of nuclei and will allow us to predict new, unknown properties successfully. At present we must restrict ourselves to the investigation and correlation of all known nuclear properties on a semi‐empirical basis. This book is devoted in its entirety to this task.”This task is indeed an enormous one, which hardly any other authors have ever attempted to achieve in a textbook, mainly because of the rapidly accumulating experimental facts that demand interpretation. Although Blatt and Weisskopf state that they had to omit many details and special developments, this relatively small volume covers almost all the aspects of theoretical nuclear physics and critically distinguishes between well‐established fundamentals and more speculative

摘要:

A co‐operative plan for preparing translations of Russian scientific literature has been put into effect by the Department of Scientific and Industrial Research, Cunard Building, 15 Regent Street, London, S.W.I, Great Britain. A wide variety of journals is included in this service, and translations are made if two or more requests are received for the same paper. The cost is on a sliding scale per page, with the minimum charge for cases where nine or more requests have been received. Full details, with contents lists of the journals covered, are contained in the monthly Translated Contents Lists of Russian Periodicals, published by H.M. Stationery Office, P.O. Box 569, London, S.E.
