Sayfa 273 - The members of the special committees on concrete and reinforced concrete of the American Society of Civil Engineers, the American Society for Testing Materials, the American Railway Engineering and Maintenance of Way Association, and the Association of American Portland Cement Manufacturers met at Atlantic City, NJ, on June 17, 1904.
Sayfa 275 - ... president or some other representative of each society be appointed to serve on the national advisory board for the investigation of fuels and structural materials. . In response to this invitation a meeting was held in Washington, DC, June 3, 1905, in the office of the Director of the United States Geological Survey. Later the personnel of this board was slightly changed, and in March, 1906, the members received direct appointments from President Theodore Roosevelt.
Sayfa 205 - experimenters are born, not made." He should keep constantly in mind the end to which his experiments tend, and understand clearly the effect of every step in the progress of his tests, and its influence on the final result.
