Abstract: Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 and again in mid-October 1972. Concentrations of inorganic nitrogen, organic carbon, or phosphorus were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for recovery from degradation, although a number of streams east of the Allegheny and Monongahela Rivers are marginal or lacking. Regionally, sulfate is the dominant ion and was observed in concentrations of 40 milligrams per liter or more at 90 percent of the sites. Bicarbonate exceeded 100 milligrams per liter at 22 sites. A moderate to high degree of mineralization is indicated by conductance readings of more than 500 micromhos per centimeter at half of the sampling sites.

Report describing the interferometric measurement process using a laser light source and a Kosters type gage block interferometer. Continuous evaluation and refinement of the process is aided by statistical treatment and control chart techniques. All error sources, both random and systematic, are evaluated and the process is maintained in a state of statistical control.

An index of names of new fossil plant genera found in literature between 1966 and 1973 which is now included in the pendium Index of Paleobotany.

Report is a guide to Standard Reference Materials (SRM's) and should be useful to all users of SRM's particularly those in countries developing national measurement systems. It is not intended to be an exhaustive description of the NBS-SRM program, but rather a review of the role SRM's play in the measurement system, how SRM's are certified, and what the certification means. To illustrate the use of SRM's, several selected industries are described in which SRM's have made significant contributions.

A list of stratigraphic names adopted, revised, reinstated, and abandoned. The nomenclatural changes pertain to geology.

A paper which provides a list of nomenclatural changes. The list also contains publications, the authors, and the names of the reports.

Report discussing elastic scattering and diffractive production processes induced in nuclear targets by high energy projectiles. Special attention is paid to the interaction of high energy hadrons and photons. The common features of all these processes are emphasized throughout the article: The multiple scattering and shadowing processes inside of the target nuclei. An effort is made to develop a unified way of treating nuclear interactions of particles which are either hadrons or exhibit some hadronic components in such interactions.

Report containing "[t]he principles and the mathematical details of a fully relativistic nuclear theory" (p. v). Appendix begins on page 124.

Presented here are notes for a course in PL/I. They might serve as a guide to those who are developing a course, or as class notes for that course. They might be useful as a textbook independent of any course; as such a textbook, however, they are not self-contained because of the built-in assumption that they will supplement lectures and be accompanied by manuals. Very nearly the full language is taught here, with the emphasis on concepts rather than practical details. Discussion of I/O is avoided until roughly the midpoint of the course. The hoped-for consequence for students is an enhanced perception and understanding of the many concepts and their logical relationships. The dawning of the age of transportability for PL/I programs gives the user a reason, for the first time, to avoid convenient but illegal language.

Report presenting new measurement techniques used to obtain potential curves, f-values, and kinetic behavior for Hg2. The Hg2 molecule is representative of a class of molecules which have dissociative ground states and bound excited states. It can therefore be used as a prototype of this class of molecules which are of interest as potential new laser candidates. Because of the non-bound ground state, standard absorption spectroscopic techniques cannot be used to obtain the necessary information about the excited states.

Report issued by the U.S. Bureau of Mines discussing costs of strip mining reclamation. As stated in the introduction, "the Bureau of Mines has undertaken this study to determine, as accurately as possible, the actual costs of reclaiming strip mined land in conjunction with active mining operations" (p. 2). This report includes tables, illustrations, and photographs.

From introduction: The specific purpose of the digital model study was to develop a better understanding of the aquifer system and to show how it responds to various pumping stresses. The scope of the study was to develop a single-transmissive-layer model that could be used to evaluate the effects proposed ground-water development schemes would have on water levels.

This document contains topographic maps for Lubbock and Plainview, Texas for an aerial radiometric and magnetic survey.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey of a region of Northwest Texas which covered the Lubbock and Plainview Geologic Atlas Maps. The area shown on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles. A total of 47 map lines were surveyed spaced at 3-mile intervals beginning at latitude 33000' and ending at latitude 350

Report of the U.S. Energy Research and Development Administration presenting aerial radiometric and magnetic survey data of the Lubbock and Plainview areas in northwest Texas.

Introduction: This report summarizes the results of the study and presents technical information on the water resources of the basin for hydrologists, engineers, planners, and water managers who need this knowledge to guide their endeavors. A brief lay-reader report describing this study is also in preparation for those who may be interested in the general findings and highlights of the investigation without the detail and data compilations contained in this report.

Introduction: This report presents the results of a subsurface uranium favorability study of the Morrison Formation in southwestern Colorado and southeastern Utah. The project began November 1, 1974 and was concluded April 11, 1975. The study was carried out under the auspices of the Grand Junction Office of the Energy and Research Development Administration (ERDA).

From abstract: Conventional direct sampling methods of airport pavement evaluation interfere with aircraft operations; therefore, an evaluation procedure based on nondestructive vibratory testing was developed.

From abstract: Extensive agricultural land clearing and drainage operations underway in a 650 square mile part of the Albemarle-Pamlico region--a 1,634 square mile peninsula in North Carolina lying between Albemarle Sound on the North and the Pamlico River on the south--are changing the hydrology of the area. The artificial drainage system being constructed in the region, although it will probably result in only a slight modification of the natural annual evatranspiration, overland runoff, and ground-water discharge, will likely result in several important problems.
