"The current study contributes toward understanding the influence of congestion pricing on commuter behavior by specifically examining what dimensions of commute travel behavior are affected as a response to congestion pricing."

The following document is a compilation of quarterly reports from August 1946 to November of 1947 from the Biology Division of the University of Chicago.

Letter from Imperial Sugar Company to brokers and trade discussing a cancelled wire transfer.

Report describing threats to waterways in the Great Lakes area by invasive carp species. It includes background about the various species, the potential negative impacts and federal responses, as well as litigation, international concerns (regarding Canada), and areas of interest for Congress.

The following quarterly report is the third in a series that discusses the investigation on the production of purified graphite through the use of self-purifying raw materials, covering the period of January, February and March of 1952.

From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

Report documenting the measuring of strontium-90 levels contained in the bones of children and adults of various age brackets across the United States.

Report regarding ion chamber measurements made of the external environmental radiation in various location in the United States during the summer of 1957.

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."

Report documenting the development phase of a multiple-source, urban atmospheric dispersion model that describes environmental transients.

Report issued by the Argonne National Laboratory discussing the Conference on the Toxicity of Carbon 14. At the outset of the meeting it was emphasized that the group was brought together to discuss work which had a bearing on the toxicity of C14 compounds used either clinically or industrially, and the hope was expressed that the group might be able to reach some conclusions on these matters. This report includes tables.

Technical paper issued by the Bureau of Mines over the development of gas masks designed for fighting fires. The characteristics of the different types of masks in development are presented. This paper includes tables, illustrations, and photographs.

From Abstract: This report provides background and procedural information for the use of a general-purpose Stirling-engine analysis code developed at Argonne National Laboratory and available through the National Energy Software Center. Different engine configurations are easily specified, or the user may make use of provided data for existing engines, both kinematic and free piston. The code models heat transfer and fluid mechanics throughout the engine and accounts for system energy flows and losses. Good agreement is shown between code predictions and experimental measurements. The present analysis method was chosen for fast execution and useful information on energy flows in the system. A description is provided of the code structure that is intended to accept different analysis modules that can provide improved system modeling or optimization capability.
