We have set ourselves the problem of calculating the laminar flow on a body of revolution in an axial flow which simultaneously rotates about its axis. The problem mentioned above, the flow about a rotating disk in a flow, which we solved some time ago, represents the first step in the calculation of the flow on the rotating body of revolution in a flow insofar as, in the case of a round nose, a small region about the front stagnation point of the body of revolution may be replaced by its tangential plane. In our problem regarding the rotating body of revolution in a flow, for laminar flow, one of the limiting cases is known: that of the body which is in an axial approach flow but does not rotate.

Previous investigations that the pancreas is a radioresistant organ. Ivy in 1924 noted the presence of a fibrotic atrophic pancreas in a dog which had received one erythema dose to the epigastrium. Fisher in 1923 reported that four to five erythema doses delivered in a single application caused complete disappearance of the irradiated pancreatic remnant in about two months. These dogs died because of uncontrolled diabetes. One dog that received four erythema doses (possibly 200 r) was sacrificed after five months. At autopsy the irradiated pancreas had disappeared, but 275 mgm of regenerated pancreas were found at the base of the main duct and 100 mgm at the base of the accessory duct. Leven in 1933 implanted radon seeds into the pancreas. Dosages varied from 528 to 1584 millicurie hours. At postmorten the pancreas surrounding the seeds demonstrated fibrous atropy and foci of necrosis. The islets appeared normal but were relatively larger in size. Rauch in 1952 reported that dogs given 200 r in air over the pancreas on alternate days until a total of 1600 r was received failed to show any histological changes after two months. Lushbaugh and Spalding and Lushbaugh reported that over 1500 r of whole-body …

Report presenting a wind tunnel investigation to determine the downwash angles, dynamic pressure loss, and wake width behind wings with sweep angles of 45, 30, and 0 degrees. Results indicated that the spanwise distribution of downwash was affected by sweep in a manner similar to span loading, increased toward the root by sweepforward and toward the tip by sweepback.

Report presenting a correlation of carbon deposition of 19 fuels in a turbojet combustor as a function of the boiling point and of the flame height at the sooting point of the fuels in a simple wick lamp for a particular combustor operating at a single set of conditions. Two similar investigations with different combustors, operating conditions, and nine different fuels yielded similar correlations on the same graph.

Report presenting a wind-tunnel investigation to determine the effects of a section modification on the aerodynamic characteristics of a wing with 35 degrees of sweepback. The wing was modified by increasing the leading-edge radius of the NACA 64A010 section and adding a small amount of camber to the forward portion of the chord. Lift, drag, pitching-moment, and trailing-edge-flap hinge-moment characteristics of the modified wing are compared with results from the original wing.

Report presenting the effects of fuel properties and change in simulated engine operating conditions on carbon deposition in an annular turbojet combustor. The fuel properties examined included specific gravity, volumetric average boiling temperature, hydrocarbon type, and hydrogen-carbon weight ratio. The fuels included hydrocarbons of the paraffinic, olefinic, and aromatic types as well as fuel mixtures.

Report of progress on the metabolic properties of various materials, biological studies of radiation effects, health chemistry and physics.

Summary: "Forty tests were conducted with two amphibious tracked vehicles and one amphibious wheeled vehicle at Eglin Air Force Base, Fla., and near Khon Kaen, Thailand, to determine the vehicles' capabilities for exiting closed bodies of water. Empirical relations, based on the data collected in this study and in previous studies, are presented to support the conclusions that performance of amphibious tracked and wheeled vehicles (in terms of "go-no go") in the water-land interface can be correlated with soil strength (expressed as average cone index of the 0- to 6-in. soil layer), and that the slope-climbing ability in the water-land interface of the tracked vehicles tested compares favorably with that of the same vehicles operating on land surfaces of similar soil composition and consistency" (p. ix).

From Abstract: "This report is one of a sequence of quarterly reports, each designed to up-date its predecessor beginning with HASL-42, "Environmental Contamination from Weapon Tests." Herein are reported data which have accrued since HASL-51. In particular, the levels of strontium 90 in fallout, milk, tap water, vegetation, and foods are given, based on data available from November 1, 1958 to January 30, 1959."

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Scranton quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

"This report describes work performed by the U.S. Environmental Protection Agency (EPS), Environmental research laboratory, Narragansett, R.I. (ERLN), as part of the Interagency Field verification of Testing and predictive Methodologies for Dredged Material Disposal Alternatives Program or the Field Verification Program (FVP)."

This report covers the research, development, and management activities of the programs involving high-performance lithium-aluminum/iron sulfide batteries at Argonne National Laboratory (ANL) and at contractors' laboratories during the period October 1980 through September 1981. These batteries, which are being developed for electric-vehicle propulsion and stationary energy-storage applications, consist of vertically oriented prismatic cells with one or more inner positive electrodes of FeS or FeS2, facing negative electrodes of lithium-aluminum, and molten LiCl-KC1 electrolyte.

From introduction: This report is a summary of the lecture material in the training course held at Idaho Falls, Idaho, to familiarize members of radiological assistance teams with information helpful in the response to an unusual accident including release of radioactive materials to a populated environment.

From introduction: This report is a survey of the composition and abundance of the various species of fish present. Other features to be noted are the rate of growth and the condition of the individual fish as indicated by the relationship between the length and weight. In addition, observations on the success of reproduction, the ability of any species to maintain itself as an integral part of the population and food supply.

Abstract: This Directory provides limited information about some 388 Federal laboratories with ten or more full-time professionals engaged in research and development. Summary data arranged by Federal agency and by State provide a broad overview of the Federal laboratory system. Laboratory lists by staff size, by State and by agency provide a cross reference. For each laboratory, a contact for obtaining technical information is given by name, address, and phone number. Major mission and major scientific or testing equipment is listed for each laboratory.

Report issued by the U.S. National Bureau of Standards discussing results of a survey conducted on automatic mechanized indexing and data processing. As stated in the introduction, "it has concentrated on the major developments in and related demonstrations of automatic indexing potentialities. Examples are also given of indexes compiled by machine and of potentially related research efforts in such areas as natural language text searching, statistical association techniques used for search and retrieval, and proposed systems for concept processing" (p. 1). This report includes an illustration.
