A handbook of mathematical functions that is designed to provide scientific investigations with a comprehensive and self-contained summary of the mathematical functions that arise in physical and engineering problems.

A bibliography that lists about 1,300 U.S. Geological Survey publications related to coal and published prior to January 1, 1971.

From introduction: This report specifies the connections from units to the Highway in sufficient detail to ensure compatibility between units from different sources of design and production.

From introduction: This report covers all aspects of an energy system based on nonfossil synthetic fuels and includes discussions on the production of the fuels; their storage, transmission, and end uses; and an overall systems analysis illustrating the role these fuels might assume in the future.

Report issued by the Bureau of Mines over development of geophysical equipment. Methods and instruments used during the studies are presented. This report includes tables, maps, and illustrations.

Report issued by the Bureau of Mines over petroleum reservoir pressure distribution. As stated in the introduction, "the purpose of this investigation is to provide the petroleum engineer with the computer techniques to determine quickly the pressure distribution in a petroleum reservoir" (p. 1). This report includes tables, and illustrations.

Report issued by the Bureau of Mines over the oil yields at the Green River. The average oil yields from the area are discussed. This report includes tables, and illustrations.

Introduction: This report was started as part of a study of the North Cascade Primitive Area, an area of about 830,000 acres, which adjoined the Canadian border on the north and which extended from Mount Shuksan on the west to Rock Mountain on the east. In the fall of 1968, Public Law 90-544, 90th Cong., reclassified the North Cascade Primitive Area and certain other national forest lands and created the North Cascades National Park, the Ross Lake National Recreation Area, and the Pasayten Wilderness. Ross Lake National Recreational Area, a corridor 21/2-4 miles wide along the Skagit River and its dammed portions, Ross, Diablo, and Gorge Lakes, separates the park into two parts and separates the northern part of the park from the Pasayten Wilderness. The present study concerns those parts of North Cascades National Park and the Ross Lake National Recreation Area that are north of Skagit River and west of Ross Lake (fig. 1), as well as part of the Mount Baker National Forest west of the park (pl. 2).

From contributions of astrogeology: The principal goal of research in astrogeology is the solution of several cardinal problems of geology...The present volume is the first of a series of professional papers that will describe major results of research in astrogeology.

Summary: The motion of Rifle Gap Dam was measured in September 1969 during the Project RULISON underground nuclear explosion. The observed response was then compared with the response computed in a mathematical model. Observed and computed responses were similar. From this study it appears that the mathematical models used are applicable to the design and analysis of soil structures, at least for ground motion intensities comparable to those observed at Rifle Gap Dam. (p. xi).

Report regarding refraction seismic and vibratory tests conducted on a railroad test embankment near Aikman, Kansas as well as attenuation and dynamic laboratory tests. The refraction seismic tests indicated the existence of two distinct velocity zones, one for the embankment and one for the underlying limestone bedrock.

Abstract: This report presents some of the results of the past year's work in a continuing study of thermionic converters. It is a study of the basic processes in thermionic diodes, and the application of this basic information to the achievement of practical thermionic energy conversion.

Various flow visualization results at a nominal Mach number of 5 are presented for cylindrically blunted, unswept and 60-degree swept fins with and without small clearance gaps, partially immersed in a turbulent boundary layer of about 2.6 inches thickness. In addition, pressure and heat transfer measurements were obtained on the flat plate upon which the fin was mounted. Oil smear, azobenzene and Schlieren flow visualization tests were made.

A preliminary map showing the lithology of parts of the Powder River Basin, Wyoming.

This is a preliminary map of the east-west cross section, Powder River Basin, Wyoming.

This map shows geologic formations of sandstone, shale, siltstone, mudstone, and coal, carbonaceous markers, coal seams, creeks and rivers, draws and gulches, mountains, buttes, and numbered locations of uranium test holes.

Base map from U.S. Geological Survey, Forks Ranch, Quietus, and Bear Creek School at scale 1:24,000.

In this report, information is presented by means of tables and illustrations preceded by brief explanations. It includes the agencies collecting the data, the number of stations located on surface and ground waters where temperature measurements are made, the distribution of stations by States and by the 21 regions of the Water Resources Council.

The report consists of three principal sections; environmental setting, water resource management, and the hydrologic system. The environmental setting describes the land and people as related to water resources. The section on water resource management is intended to provide practical information needed for the planning and management of water resources. The section on the hydrologic system is a more technical discussion of water in the Red River basin. The section on water management can be used to locate the water, determine the amount available and its quality; whereas, the section on the hydrologic system describes the operation of the system how water moves through the system and why the quality is as it is.

A report regarding the Precambrian through Cretaceous strata of probable fluvial origin in southeastern United States and their potential as uranium host rocks.

From Abstract: "This report summarizes a systematic 20-year study of the organic sulfur compounds in Wasson, Texas, crude oil and, to a lesser extent, of three crude oils, that culminated in some 200 individual sulfur-compound identifications. This report reviews early sulfur literature covering petroleum sulfur compound identifications completed before this study was begun, and cites 58 papers resulting from this work."

From Abstract: "The compositions of various gums and inorganic deposits are reported in terms of elemental analysis and spectroscopic examinations. The reactions of tetraethyllead with selected hydrocarbons are also reported."

Ruler issued by the United States National Bureau of Standards. The front includes measurements in centimeters (to 15) and inches (to 6); there is text on the back comparing metric and customary units for length, volume, and weight.
