Thermal expansion anomalies of R(Fe, M)(12) (R=Y, Nd; M=Mo and Si)
No full textStructural and thermal-expansion anomaly studies on R(Fe,M)(12) (R=Nd and and Y, M=Mo and Si) compounds were performed by x-ray diffraction. Mo atoms occupy the 8i site. While Si atoms occupy the 8f and 8j sites but not the 8i site. Thermal-expansion anomaly shows only in ab plane in the Mo compounds, while becomes very weak and along with only the c axis in the Si compounds. The anomaly was attributed to the contribution of the interactions of short Fe-Fe distances similar to the previous explanation on other R-Fe intermetallics and that of other strongly positive interactions such as 8j-8j.

Letter from Thomas R. Bodine, American Friends Service Committee Seattle office, to Mary M. Kimber, May 25, 1942
No full textLetter from Thomas R. Bodine to Mary M. Kimber, asking Kimber to visit individuals from the Puget Sound area incarcerated at Pinedale Assembly Center: Rev. Daisuke Kitigawa, Waichi Oyanagi, Chisako Higuchi, Mutsuo Hasiguchi and Mrs. Matsuoka, Makato Kobukata, the Hirabayashi family, and Violet Yokoyama. A note in pencil at the top of the page: "Burcham." A response letter from Grace and Calvin Coke to Thomas R. Bodine is found in item: chs_ms840_0306.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
Evaluation of speed and accident reduction through increased traffic law enforcement
No full textIncludes bibliographical references (leaves 58-59)Increased traffic law enforcement activities were implemented in six Texas counties in an effort to reduce traffic speed and accidents on selected rural roadways. Patrol activities, in addition to normal enforcement efforts, were continued for a 5 month period from August 13, 1979 until December 15, 1979. Speed and accident data were collected and analyzed throughout the study in order to assess the degree of reduction achieved. Data were also collected on several patrol measures in order to evaluate the effort necessary to bring about specified reductions in the traffic parameters of interest. The results indicate that increased patrol activity had the effect of decreasing mean vehicle speed and the percentage of motorists exceeding 55 mph over time. Mean speed was reduced 2.4%, and percent exceeding 55 mph was reduced 19%. Increased patrol activity, in reducing speeds, seems to have the effect of reducing the frequency and severity of accidents. Injury accidents were reduced 9.5%, and property damage accidents were reduced 11.3% on treatment roadways. Regression analyses indicated that a three variable model of speeding tickets per mile of roadway, total number of speeding tickets, and total number of warnings predicted the reduction in mean speed and percent exceeding 55 mph better than a single factor or other multi-factor models. A systematic relationship between patrol activity and accident reduction was not discovered. A set of administrative guidelines were developed based on a regression analysis on the variable speeding tickets per mile. These guidelines provide information regarding the expenditures required to bring about specified degrees of change in speed parameters and are applicable to programs employing increased patrol activity in rural areas over a 5 month period
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
