The predicted flux on the earth of solar neutrinos has eluded detection, confounding current ideas of solar energy production by nuclear fusion. The dominant low-energy component of that flux can be detected by mass-spectrometric assay of the induced tiny concentration of 1.6 x 10(7) year lead-205 in old thallium minerals. Comments are solicited from those in all relevant disciplines. 相似文献

The Antiquities Act of 1906, which has provided the legal basis for protecting the U.S.'s prehistoric and historic heritage, is no longer adequate. Artifact hunters and collectors have descended on national forests and U.S. parks in ever-increasing numbers. The drafters of the 1906 act could not have anticipated the lucrative market in prehistoric artifacts in the 1970's. The act has come under attack in the courts as being unconstitutionally vague. In light of the recent criminal prosecutions under the Antiquities Act and the constitutional challenges, reviewed in this article, the authors propose a new Antiquities Act which expands the scope of the act to include those who would deal in artifacts taken unlawfully from federal lands and increases the criminal penalties for a violation of the act. 相似文献

A major component of the Inter-Union Commission on Geodynamics Project, labeled "Internal Properties and Processes," included certain experimental and theoretical research in tectonophysics, seismology, geochemistry, petrology, volcanology, and planetology. This review focuses on a few research areas in which there have been surprises and reversals. In particular, attention is given to the attempts to quantify the thermal profile in the earth's interior and the material properties of the earth's interior. 相似文献

As part of today's quickened effort to upgrade the quality and quantity of nuclear structure physics research, many program proposals are being made by colleges and universities both here and abroad. Mindful of the high degree of interest in these proposals, High Voltage Engineering Corporation is planning to publish excerpts from some of them in the hope you will find them both stimulating and informative. 相似文献
