摘要:
Current ideas about the moon appear to be mistaken on two fundamental points. First, at least within certain large classes of lunar craters, internal origin (i.e., some form of volcanism) predominates over impact; this result raises questions about the reality of the “era of violent bombardment.” Second, the origin of tektites by meteoritic impact on the earth cannot be reconciled with physical principles and is to be abandoned. The only viable alternative is origin by lunar volcanism, which implies the following: continuance of (rare) explosive lunar volcanism to the present time; existence of silicic lunar volcanism and of small patches of silicic rock at the lunar surface; a body of rock in the lunar interior, probably at great depth, which is closely similar to the earth's mantle and which contains billions of tons of volatiles, probably including hydrogen; and origin of the moon from the earth after the formation of the earth's c

摘要:
Could a large earthquake, like the one that occurred near Charleston, S.C., in 1886, strike elsewhere along the eastern seaboard, or is there a geologic structure, unique to the Charleston area, that was responsible? Because of the lack of hard evidence linking eastern earthquakes to specific geologic structures or faults, the answer to that question has been the subject of much scientific debate. Because of this uncertainty, some scientists have maintained that strong earthquakes conceivably could occur anywhere along the east coast. The Charleston earthquake measured more than 7 on the Richter scale and caused at least 60 deaths and widespread damage. Among other considerations, the design of nuclear power plants is affected by how well scientists can predict the seismic potential of a given area.

摘要:
Streamflow conditions in the Midwest and Southwest were generally average to well above average during January, but many streams in the East—in a broad band from Maine to Florida and west through Alabama—reported well below average flows for the month, according to the U.S. Geological Sur

摘要:
This book presents the elements of process design and of hydraulic design for water and wastewater treatment plants. In particular, hydraulic principles and methods are given for the analysis and design of flows in pipe systems and open channels, for the characteristics of flow measurement devices, and for single and multiple pump operation and selection. These fundamentals are used to illustrate the steps in the hydraulic design of a wastewater treatment plant. In addition, the hydraulic design of pipe manifolds (for distributing flow amongst basins) and of diffusers (for distributing treated wastewater to a body of water) is presented.

摘要:
During the International Magnetospheric Study (IMS), a vast data set was acquired which is presently being brought to bear on solving some of the outstanding questions regarding magnetospheric dynamics. The data involve plasma and field parameters measured on satellites both in the magnetosphere and in the interplanetary medium, as well as ground‐based magnetometer, riometer, and photometer array measurements which can be used to diagnose the state of magnetospheric activity. The data acquisition phase of the IMS concluded at the end of 1979, although some instruments are operating to this day. Since the end of 1979 an intensive effort has been underway to analyze and interpret the data base, and some of the successes of this effort were recently reported in the Symposium on the Achievements of the IMS, which was held in late June in Graz, Austri
