Simulation Of Particle Tracks In Emulsion, Thomas E. Furtak, Robert Katz

Micrographs of energetic particles in nuclear emulsion are simulated by computing the spatial distribution of developed grains with the δ-ray theory of track structure, and representing the developed grains by points of light on an IBM 2250 visual display unit. The simulated tracks display many of the features of actual track structure and serve as a visual comparison between experiment and theory,

Dielectric Polarization And Alignment And The Structure Of Polar Fluids, John D. Ramshaw, D. W. Schaefer, John S. Waugh, J. M. Deutsch
Dielectric Polarization And Alignment And The Structure Of Polar Fluids, John D. Ramshaw, D. W. Schaefer, John S. Waugh, J. M. Deutsch
Physics Faculty Publications and Presentations
An analysis is made of the information about the structure of dense polar fluids which resides in the dielectric constant, the Kerr constant, and the nuclear magnetic resonance (NMR) quadratic electric field effect. The inadequacy of the "local-field" model for liquids is discussed. The existence of a nonzero molecular hyperpolarizability is shown to destroy an equivalence which would otherwise exist between the Kerr and NMR experiments, and can easily account for apparent discrepancies between the reported Kerr and NMR data for nitrobenzene and nitromethane. A method is presented for removing dielectric boundary effects from statistical averages, so that the averages …
Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz
Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz
Faculty Publications
Using a set of commercially prepared sodium ferrocyanide absorbers enriched to 91.2% Fe57 the Lamb-Mössbauer factor was measured to be 0.28±0.03. The thickness of Fe57 for these absorbers was measured using x-ray absorption techniques and was found to be considerably smaller than that advertised by the manufacturer even after correcting for the size of the ferrocyanide particles in the absorbers.

A Study Of Primary Productivity In A Nebraska Interstate 80 Lake, Gilbert Adrian, Carl Throckmorton, Bob Mcdonald
Nebraska Game and Parks Commission: Staff Research Publications
The primary productivity of a small gravel pit lake in the Platte River Valley of Nebraska was studied for a 2-year period. Daily production rates were estimated from near weekly samples, with calculations done by computer. Emphasis was placed on production under ice during winter conditions. Annual production was estimated and is compared with several other lakes in North America.

Let {V(t,ω), t ≥ O, ω ε Ω} be a diffusion process on the real line with infinitesimal operator 1/2σ2(⋅)D2 + m(⋅)D. Markov processes {Vn, n = 1,2,....} on the real line are constructed in such a way that the paths of Vn are step functions with jump size n-1/2 and
PO [lim sup |Vn(s)-V(s)| = 0] =1
n∞ 0≤s≤t,
where PO assigns probability one to paths starting at the origin at t = 0.

Theory Of Relativistic Magnetic Dipole Transitions: Lifetime Of The Metastable 2s3 State Of The Heliumlike Ions, Gordon W. F. Drake
Theory Of Relativistic Magnetic Dipole Transitions: Lifetime Of The Metastable 2s3 State Of The Heliumlike Ions, Gordon W. F. Drake
Physics Publications
It has recently been established that the radiative lifetime of the metastable 2S3 state of helium and the heliumlike ions is determined by single-photon magnetic dipole (M1) transitions to the ground state, rather than the two-photon process proposed by Breit and Teller. The theory of nl-n′l M1 transitions with n ′ is developed in the Pauli approximation and extended to two-electron systems. Terms arising from relativistic energy corrections and finite-wavelength effects are included. The results for hydrogenic systems are shown to be identical to those obtained in the relativistic four-component Dirac formulation. The coefficients in the Z-1 perturbation expansion of …

Don't Crop Areas Liable To Waterlogging, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The increasing areas of crops being sown in high rainfall districts make it likely that many crcp areas include sections liable to severe waterlogging.
This report presents results of a 1970 trial which clearly show that sowing such sections is not economic.

Mossbauer Study Of An Intramolecular Antiferromagnet, R. Lechan, C. R. Abeledo, R. B. Frankel
Physics
Mossbauer measurements at 4.2 ≤T ≤ 22 K and OsHosBO kOe are + reported in (Fe Salen Cl)2, a molecular complex containing two coupled Fe3+ ions bridged by oxygen atoms. At 4.2 K only the ground state with effective spin S = 0 is appreciably populated. Analysis of the magnetic field and temperature dependence of the magnetic hyperfine field yields an exchange constant J= -6.7 cm>sup>-1 and a hyperfine field of -192 kOe per unit spin at each Fe3+ nucleus.

Growing Plants With Salty Water, C V. Malcolm, S. T. Smith
Journal of the Department of Agriculture, Western Australia, Series 4
LACK of good quality water in many parts of Western Australia often forces people to use salty water for irrigation and gardening.
This article gives some hints on how to reduce salt damage to plants when salty water must be used for irrigation or gardening.
It includes a table of plants which may be irrigated with water of varying degrees of salinity and lists precautions which should be taken for each group.

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Journal of the Department of Agriculture, Western Australia, Series 4
High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.
This article describes the technique and discusses its possibilities on the Ord.
The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.

Range Evaluation Using Aerial Photography, D G. Wilcox
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture, in association with the University of Western Australia, recently undertook a study of the application of aerial photography to range condition monitoring in three rangeland types in the mulga zone of Western Australia.
The project was financed by the Rural Credits Development Fund and the C.S.l.R.O. Rangelands Research Unit.
This article deals in a general way with the possible use of aerial photography in rangeland administration.
