We investigated the relative biological effectiveness (RBE) of fast neutrons compared with X-rays in impeding development of immunity to an infective agent, the intestinal cestode Hymenolepis nana. Mice were irradiated with neutrons or X-rays and 2 days later given an immunizing dose of H. nana eggs. After another 2 days, the mice received a challe

The results of test programs conducted by the Protection and Survival Laboratory to investigate the performance of prototype or operational seating and restraint systems relative to their ability to provide protection against crash injury and to investigate the performance of anthropomorphic dummies in the dynamic environment are reported. The data

This document reviews three phases of a study conducted to evaluate and improve the crashworthiness of passenger carrying vehicles in intercity service. Phase I surveyed the accident data over a period 1966 to 1973 and identified those areas responsible for the mS3jority of accidents involving human injury (both operating personnel and fare-paying

This report is written in two sections. Part A deals with the results the second sampling (designated I+6) of the experimental sulphur-asphalt test sections on U.S. 77 in Kenedy County, Texas. The initial sampling (designated I) was reported earlier (Ref. 3) and is also included in this submission for comparison purposes. The second section, Part B

In our discussions with various railroad personnel, suppliers, and consultants, we are left with the impression that yard design know-how is possessed by a handful of people scattered within the railroad industry. Most of their valuable knowledge is either undocumented or obscurely documented. The need for a systematic compilation of this scattered

The objective of this study was to determine the magnitude and characteristics of safety problems, in terms of reported accidents, that are associated with moving vehicular traffic around and through highway maintenance and utility work zones. This was accomplished by examining 280 maintenance and utility work zone accidents that occurred on the Vi

This study will analyze the potential effects of multiple car hard red spring wheat rates on the country elevator industry in North Dakota. The study will base its analysis on data developed from a mail survey of North Dakota country elevator operators and the historical grain movements from these elevators.
This study was conducted to provide information related to the post-crash evacuation of intercity buses. A review of bus accident data and relevant I literature was completed to provide an understanding of the variables related I to bus evacuation. A survey was completed to document the passenger characteristics of a typical bus load. A special dat

This study examines the methods used for evaluating transportation developments, particularly those for disadvantaged groups. Two methodological questions are examined: what measures characterize the social condition to be ameliorated, most effectively utilized? and in what evaluation framework are these measures The social condition is interpreted

An evaluation of the laws of Virginia governing pedestrian movement and the operation of bicycles and motorcycles revealed that a number of changes are called for. Comparisons between current Virginia law, the Uniform Vehicle Code (U.V.C.) and selected statutes from other states dramatize the need for amendment. The language of the proposals presen

This study was undertaken to develop a permeable yet stable, asphalt-treated, layered shoulder drainage system for a typical pavement section. Stability and permeability characteristics of several mixes were evaluated in the laboratory. Two installations were constructed in North Louisiana on Interstate 20 using the design criteria established by t
...
This study attempted to correlate measured X-ray intensities with concentrations of each member of paint pigment systems, thereby establishing calibration curves for the quantitative analyses of such systems.
The cold weather paving specification for bituminous concrete adopted in 1970 was reexamined to determine its effectiveness and any need for revisions. Density and temperature measurements were obtained on five field projects and observations were made of the rolling practices employed. The results and feedback from field personnel were used to rec

The purpose of this study was to determine the Department's needs for traffic count data, to relate them to an evaluation of the traffic count programs and procedures, to identify problems and deficiencies with data requirements, and to seek means of improving the programs. In approaching these objectives, interviews were conducted with representat

During the summer of 1977, field surveys and conferences with Virginia Department of Highways and Transportation district personnel were conducted to determine the statewide status of maintenance efforts in erosion, and sedimentation control. As a result of this study two types of problems were identified: (1) field, and (2) administrative and pers
