Segregation Of Copper To The Surface Of Copper-Nickel Alloys, Peter A. Dowben
Segregation Of Copper To The Surface Of Copper-Nickel Alloys, Peter A. Dowben
Peter Dowben Publications
Copper segregation profiles at the surfaces of Cu17Ni83(111) and Cu17Ni83(100) have been calculated by a semiempirical procedure based upon previously published data. These profiles indicate that surface enrichment of copper is not limited only to the topmost layer but occurs for several layers away from the surface as well. A comparison of the calculated segregation profiles based upon the experimental results for the (100) and (111) surfaces of Cu17Ni83 do not agree with predictions based upon thermodynamic models of segregation.
Lattice Dynamics Of Mixed Crystals Of Tise2, Roger D. Kirby, G.A. Freund, Jr.
Lattice Dynamics Of Mixed Crystals Of Tise2, Roger D. Kirby, G.A. Freund, Jr.
Roger Kirby Publications
We present the results of Raman scattering measurements on the mixed-crystal systems TiSe2-xSx, TiSe2-xTex, ZrxTi1-x Se2. At room temperature with the pure compounds all have crystal structures represented by the D3d(P3̃m1) space group with three atoms per unit cell. There are two Raman-active k=0 phonons, one of A1gˉ symmetry and one of Eg symmetry. In the TiSe2-xTex system, the A1gˉ and Egˉ phonon frequencies shift smoothly with concentration, and the shifts are well described by a simple virtual-crystal …
The Variability Of Holocene Climate Change: Evidence From Varved Lake Sediments, Walter E. Dean, J. Platt Bradbury, Roger Y. Anderson, Cathy Barnosky
The Variability Of Holocene Climate Change: Evidence From Varved Lake Sediments, Walter E. Dean, J. Platt Bradbury, Roger Y. Anderson, Cathy Barnosky
United States Geological Survey: Staff Publications
Varved sediments from a lake near the present forest-prairie border in northwestern Minnesota provide an annual record of climate change for the last 10,400 years. Climate-sensitive mineral, chemical, and biological components show that the mid-Holocene dry interval between 8500 and 4000 years ago is asymmetrical and actually consists of two distinct drier pulses separated by a moister interval that lasted about 600 years. Cyclic fluctuations with periods of several hundred years were abrupt and persistent throughout the Holocene and are most clearly recorded within the two drier pulses.
Livestock Guarding Dogs Protect Domestic Sheep From Coyote Predation In Kansas, William F. Andelt
Livestock Guarding Dogs Protect Domestic Sheep From Coyote Predation In Kansas, William F. Andelt
Great Plains Wildlife Damage Control Workshop Proceedings
Sheep (Ovis cries/ producers were surveyed in Kansas to determine the efficacy of livestock guarding dogs (Canis familiaris) for protecting sheep from coyote (Canis latrans) predation. The majority of producers rated their guard dogs' predator control performance as good or excellent, indicating. that the dogs reduced their reliance on other control methods and substantially reduced monetary losses.

Yellow Giants In Young Clusters. Ii. A Comparison Of Observation With Theory, Edward G. Schmidt
Yellow Giants In Young Clusters. Ii. A Comparison Of Observation With Theory, Edward G. Schmidt
Edward Schmidt Publications
Luminosities and effective temperatures are calculated for 17 nonvariable yellow giants and supergiants and nine Cepheids which were previously identified as members of open clusters. These stars are identified as being in the helium core burning stage of evolution. A comparison with the predictions of pulsation theory does not show any disagreement. On the other hand, several comparisons with the theory of stellar evolution produce discrepancies which suggest that effects neglected in the calculations may play an important role in the evolution of these stars.
Statistical Consulting In A Geographically Dispersed Organization, Richard M. Engeman, William E. Dusenberry
Statistical Consulting In A Geographically Dispersed Organization, Richard M. Engeman, William E. Dusenberry
USDA Wildlife Services: Staff Publications
There has been much discussion in the recent statistical literature concerning the optimal manner for a consulting statistician to operate within a larger organization. Marquardt (1979) described the "total involvement" approach, involving a statistician from conceptualization of a project to the final report; Finney (1982) discussed the questions a statistician should ask for effective consulting; and Bishop, Peterson, and Tragser (1982) argued that a statistician's most substantive contributions are made during the planning stages of a study. McCulloch et al. (1982) described a program for training statistical consultants, and Hunter (1981) discussed the roles a statistician may assume.

Model Calculations Of The Micrometer To Millimeter Intrinsic Absorption For Simple Ceramics, John R. Hardy, P. J. Edwardson, J. A. O'Gara
Model Calculations Of The Micrometer To Millimeter Intrinsic Absorption For Simple Ceramics, John R. Hardy, P. J. Edwardson, J. A. O'Gara
John R. Hardy Papers
A systematic study has been made of the strength of the intrinsic absorption, or loss, for millimeter to micrometer electromagnetic radiation propagating in simple ceramic materials. This study employed a number of model diatomic systems whose simplicity enabled the basic two-phonon decay process, responsible for this intrinsic loss, to be computed with precision, even at the lowest frequencies, on a dedicated microcomputer. It was found that, at least at low frequencies, the loss was a relatively structureless universal function of the atomic mass ratio, in general agreement with earlier results for real alkali halides. In particular, it was found that, …

After the expenditure of some $200 billion (1984$) since the launch of its first spacecraft in early 1958, the United States has obtained the scientific knowledge and developed the technological capability and professional expertise to succeed in virtually any theoretically possible civilian space venture that it may choose to undertake, But America’s second quarter-century of space activities promises to differ markedly from the first, almost wholly exploratory, era. If space is to be successfully developed in roughly the same fashion as have other, more familiar natural resources and environments, the next stage will be characterized by establishing and securing the …
Central-Peak-Soft-Mode, Coupling In Ferroelectric Gd2(Moo4)3, J. Petzelt, F. Smutny, V. Katkanant, F. G. Ullman, John R. Hardy, A. A. Volkov, G. V. Kozlov, S. P. Lebedev
Central-Peak-Soft-Mode, Coupling In Ferroelectric Gd2(Moo4)3, J. Petzelt, F. Smutny, V. Katkanant, F. G. Ullman, John R. Hardy, A. A. Volkov, G. V. Kozlov, S. P. Lebedev
John R. Hardy Papers
Transmission measurements on Gd2(MoO4)3 in the ( 5-50)-cm-1 region were performed with use of tunable backward-wave oscillator sources (5-30 cm>-1) and a Fourier spectrometer (30-50 cm>-1). The resulting dielectric spectra show an additional low-frequency dispersion which was fitted with a standard central-peak model. Its characteristic relaxation frequency is ~20 cm>-1 and the coupling between the soft mode and central mode increases near the transition temperature. This model also accounts very well for the weak anomaly in the clamped permittivity Ec measured at 63 MHz. The same central mode …

J. P. Finley: The First Severe Storms Forecaster, Joseph G. Galway
NOAA Technical Reports and Related Materials
During the 19th century, while others were debating about the theory and morphology of tornadoes, Finley set out to prove that tornadoes, like other weather phenomena, could be forecast. He developed forecast rules and made experimental forecasts. His forecasting and analysis activities made him the center of controversy during most of his professional life and led to open debate in the literature, but he set precedents in meteorological forecasting that are still valid today. His career as a meteorologist started while he was a private in the United States Army. His interest continued even when he had achieved the rank …

The Luminosity Scale Of Cepheid Variable Stars: A Revision, Edward G. Schmidt
The Luminosity Scale Of Cepheid Variable Stars: A Revision, Edward G. Schmidt
Edward Schmidt Publications
The period-luminosity-color relation for classical Cepheids is discussed in terms of a recent re-determinations of the distance moduli of open clusters with Cepheid members. The distance moduli of eight clusters with well established Cepheid members were determined from Stromgren four-color and Hβ photometry of the B stars. Possible sources of systematic errors in these distance moduli are discussed. Zero points are derived from these data for the period-luminosity-color (PLC) relation on the UBV system and the period-luminosity relations for near-infrared magnitudes. The present relations yield absolute magnitudes which are fainter by 0.4-0.6 mag than those now commonly used. The source …

Surface-Wave-Induced Interference Effects In Angle-Resolved Photoemission, Peter A. Dowben, D. Heskett, E.W. Plummer, Y. Sakisaka, T.N. Rhodin, Cyrus Umrigar
Peter Dowben Publications
New features are observed in normal-emission photoelectron spectra from Ni(100) in a narrow range of photon energies around 25 eV. These features are inconsistent with either direct transitions from the bulk or emission from occupied surface states or resonances. We suggest that they are a consequence of interference between the ordinary direct transition emitting an electron in the normal direction and the excitation from the same initial state into a final state that would normally be emitted from the surface at Γ― in the second surface Brillouin zone, but at this energy is trapped in a surface wave.
