Nuclear Orientation Of 253Es In Neodymium Ethylsulfate, A. J. Soinski, Richard B. Frankel, Q. O. Navarro, D. A. Shirley Dec 1970

Nuclear Orientation Of 253Es In Neodymium Ethylsulfate, A. J. Soinski, Richard B. Frankel, Q. O. Navarro, D. A. Shirley

Physics

Einsteinium-253 nuclei were oriented at low temperatures in a neodymium ethylsulfate lattice. From the temperature-dependent α-particle angular distribution a nuclear magnetic moment |μ|=(2.7±1.3)μN was deduced. From the values for the angular distribution function at the lowest temperatures it was possible to test the predictions of the Mang shell-model theory for the relative phases and amplitudes of the α-partial waves. As predicted, the waves of angular momentum L=0 and 2 are in phase, and the L=0 and 4 waves are out of phase. The predicted wave amplitudes are in error, especially that of the L …


Nuclear Magnetic Resonance Investigation Of The Metal-To-Semiconductor Transition In Crystalline Cdo, R. P. Benedict, David C. Look Dec 1970

Nuclear Magnetic Resonance Investigation Of The Metal-To-Semiconductor Transition In Crystalline Cdo, R. P. Benedict, David C. Look

Physics Faculty Publications

Measurements of the Cd113 nuclear-spin-lattice relaxation time (T1) and resonance frequency shift (K) were carried out in several samples of polycrystalline n-type CdO over the temperature (T) range 1.4-300°K, frequency (ν) range 2-10 MHz, and carrier concentration (Ne) range 3.3-44×1018 cm-3. For Ne>1019 cm-3, we find that T1∝Ne-2/3T-1 and K∝Ne1/3, showing that the nuclei are interacting with degenerate conduction electrons. Furthermore, the Korringa relationship holds and the calculated electron density at a nucleus is almost the same as …


A Summary Of Lake Mcconaughy Rainbow Trout Spawntaking Activities, Rod Van Velson Dec 1970

A Summary Of Lake Mcconaughy Rainbow Trout Spawntaking Activities, Rod Van Velson

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The objective of this activity is to raise and stock progeny from adult Lake McConaughy rainbow trout for the purpose of: (1) establishing spawning runs of McConaughy strain rainbow trout in streams which have the potential to support reproduction, (2) develop a stocking program for streams which have a coldwater habitat but lack suitable spawning areas (these rainbow, upon reaching a size of seven to nine inches will migrate downstream to Lake McConaughy. They will return to the streams in their third and fourth years weighing 2.0 to 6.0 pounds), and (3) providing additional life history and management information about …

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt Nov 1970

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt

Nebraska Game and Parks Commission: Staff Research Publications

The possible effects of proposed watershed management practices on fish resources of the Nemaha Basin were poorly understood; thus, a study was undertaken to ascertain the species of fish present and their relative abundance and distribution within the basin. Thirty-five species were collected, 34 of them from the Big Nemaha River system and 28 from the Little Nemaha River system. These data may be used as a basis for future studies of fish population changes in the Nemaha Basin and possibly as a basis for studies in other watersheds.

Perturbation Theory Of The Hooke's Law Model For The Two‐Electron Atom, Ronald White, W. Byers Brown Nov 1970

Perturbation Theory Of The Hooke's Law Model For The Two‐Electron Atom, Ronald White, W. Byers Brown

Center for Advanced Mineral and Metallurgical Processing (CAMP)

The Hooke model for the two‐electron atom replaces the electron–nuclear interaction by a harmonic oscillator potential, but retains the Coulomb repulsion of the electrons. The first‐order perturbation equation for the electron repulsion is solved analytically, and the exact first‐, second‐, and third‐order perturbation energies are obtained. A similar Z-1 perturbation treatment is carried out for the Hartree–Fock equation and other variational approximations. The Z-1 of the correlation energy is compared with that for helium-like atoms and found to be similar.


The Effects Of Channelization In The Missouri River On Fish And Fish-Food Organisms, Earl R. Kendle Nov 1970

The Effects Of Channelization In The Missouri River On Fish And Fish-Food Organisms, Earl R. Kendle

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Plans by the U.S. Army Corps of Engineers to channel the Missouri River from Sioux City to Yankton are of great concern to the ecologists interested in this section of the river. The channelization of the last remaining relatively natural sketch of the Missouri River below the main stem reservoirs could prove to be ecologically disastrous. As the present time too little is known in the form of scientifically proven facts of the likely effects on fish and other organisms inhabitating the river. The populations of certain species of fish far downstream from and in the section to be channelized …

Bioassay Procedures For Oil And Oil Dispersant Toxicity Evaluation, Gilles Laroche, Ronald Eisler, Clarence M. Tarzwell Nov 1970

Bioassay Procedures For Oil And Oil Dispersant Toxicity Evaluation, Gilles Laroche, Ronald Eisler, Clarence M. Tarzwell

United States Environmental Protection Agency: Staff Publications

Hazards to marine and estuarine fauna associated with offshore drilling of oil and with transport of large quantities of oils via tankers are numerous and understandable. At present, there is a growing body of evidence on adverse effects to these organisms of crude oil (1) (2) (3) (4) (5) (6) (7) (8) (9) and chemical oil counteracting agents or dispersants (5) (6) (9) (10) (11) (12) (13) (14) (15) (16) (17). These effects are well summarized by Smith (18) and by Carthy and Arthur (19).

Comparatively few workers have studied the influence of oil-dispersant mixtures of marine life. Studies by …


Digital Systems For On-Site Collection For Water Quality Analysis, M. K. Testerman Nov 1970

Digital Systems For On-Site Collection For Water Quality Analysis, M. K. Testerman

Technical Reports

A prototype system has been developed for recording and transmitting digital data at a remote water quality monitoring station in an unattended manner. As many as eight analog signals from transducers, which measure water quality characteristics such as dissolved oxygen, temperature, pH, chlorides, conductivity, redox, and turbidity, are converted to digital signals and recorded in binary coded decimal format on magnetic tape. This unit may be contacted from a central station for playback of the day's recording. The transmitted data can be recorded at the central station by teletype. Each data record includes a time-of-day "word" so that all data …

Nebraska Trappers' Guide: A Handbook On The Taking Of Muskrat, Mink, Beaver, And Coyote And The Handling Of Pelts, Edson Fichter, George Hytrek

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Management of any game or fur animal is an effort to insure an annual harvestable surplus. Much of this effort must be placed upon the land. The development and maintenance of habitat--the place where the animals can live--constitutes a large portion of this effort. The objective of habitat development is the increase and improvement of homes for wildlife and thereby the increase in numbers and improvement of the quality of the animals produced. Another important and continuous job of game management. is the annual check on populations--their ups and downs. Information on the numbers of animals is necessary if only …


Excitation Of The (2P2)3P State Of Helium Near Threshold, Paul Burrow Nov 1970

Excitation Of The (2P2)3P State Of Helium Near Threshold, Paul Burrow

Paul Burrow Publications

The trapped-electron method is applied to the excitation by electron impact of the (2p2)3P state, the lowest doubly excited state of helium which is stable against auto-ionization. The energy of this state, 59.64±0.08 eV, is in good agreement with theory. An estimate of the slope of the total cross section for excitation of the (2p2)3P state at threshold gives a value of 4 × 10-20 cm2/eV.


Instrumentation And Development Of Techniques To Measure And Evaluate Meteorological Parameters Important To Hydrology, Duane G. Chadwick Nov 1970

Instrumentation And Development Of Techniques To Measure And Evaluate Meteorological Parameters Important To Hydrology, Duane G. Chadwick

Reports

Hydro-meteorological instrumentation concepts are discussed. The necessity for an economic and reliable telemetering system is recognized and ways are shown how to achieve this objective. Particular discussion is given on total-precipitation and water-content-of-snow sensing. A method is also presented showing how to make isohyetal plots of telemetered precipitation information on an x-y plotter by use of a resistance paper method in conjunction with an analog computer.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1970 Annual Summary, Dexter S. Haven

Reports

The Applied Biology Department in the VIMS Division of Applied Marine Science and Ocean Engineering conducts. weekly surveys of oyster "setting" in Virginia rivers from the end of May through early October each year. Starting at the mouth of each river and proceeding upstream to the limits of oyster setting, the collecting areas a.re established on public and private beds. Spat counts are obtained from oyster shells strung on wire and suspended from stakes. The number of spat which set in one week on the smooth side of ea.ch shell on the string are tabulated.


Small Ring Analogs Of Acetylcholine. Synthesis And Absolute Configurations Of Cyclopropane Derivatives., Douglas Armstrong, Joseph G. Cannon Nov 1970

Small Ring Analogs Of Acetylcholine. Synthesis And Absolute Configurations Of Cyclopropane Derivatives., Douglas Armstrong, Joseph G. Cannon

Faculty Scholarship – Chemistry

Conformational rigidity has been conferred upon the OCCN portion of acetylcholine by incorporation of the C atoms into a cyclopropane ring. trans-2-Acetoxycyclopropyltrimethylammonium iodide has been prepared from an olefinic starting material, 2-vinyloxytetrahydropyran; assignment of the trans configuration to the 1,2-disubstituted cyclopropane systems was based upon literature precedent and upon nmr data, and was confirmed by X-ray crystallographic analysis. Resolution of one of the racemic intermediates in the reaction sequence was achieved, which permitted preparation of both enantiomers of the final product. X-Ray crystallographic analysis has demonstrated that the muscarinically active (+)-trans-2-acetoxycyclopropyltrimethylammonium iodide possesses the same absolute configuration …

Some Results On The Distance Properties Of Convolutional Codes, Luther D. Rudolph, Alexander Miczo

Electrical Engineering and Computer Science - Technical Reports

Rate 1/2 binary convolutional codes are analyzed and a lower bound on free distance in terms of the minimum distances of two associated cyclic codes ìs derived. Next, the complexity of computing the free distance is discussed and a counterexample to a conjecture on the relationship of row distance to free distance for systematic codes Ìs presented. Finally, an improved Gilbert bound for definite decoding is derived.
