Mössbauer Properties Of Synthetic Analogs Of Active Sites Of The Iron-Sulfur Proteins, Richard B. Frankel, B. A. Averill, R. H. Holm
Mössbauer Properties Of Synthetic Analogs Of Active Sites Of The Iron-Sulfur Proteins, Richard B. Frankel, B. A. Averill, R. H. Holm
Physics
Mössbauer spectroscopy of the synthetic tetramers [Fe4S4(SR)4]2- (R = alkyl, aryl) and the corresponding trianions obtained by one-electron reduction, when compared with available data for 4-Fe and 8-Fe iron-sulfur proteins, shows that these tetramers are electronic analogs of the active sites of the proteins.

Methyl Proton Nmr Shifts Of Coordinated Methanol In A Series Of Co(Ch,0h),X2+ Compounds, J.R Vriesenga, Jerry Goodisman
Chemistry - All Scholarship
The isotropic contact NMR shifts of the coordinated cis and tram methanol methyl proton resonances of a series of Co(CH30H)5X2+ complexes were measured, where the ligand X was pyridine, /I- and a-picoline, DMF, DMSO, acetonitrile, and water. The question of how to separate the observed shifts into their respective Fermi contact and dipolar (pseudocontact) contributions was examined in detail with the result that a new procedure for carrying out the separation was proposed. The dipolar shifts for these complexes were found to vary widely, with the acetonitrile complex exhibiting the largest dipolar shift. For the DMSO and water complexes the …
Kinectics Of The Ground State Transformation In Fe(Ii) (N, N -Dicyclohexylthiourea)6(Cio4)2, R. Latorre, J. A. Costamagna, E. Frank, C. R. Abeledo, Richard B. Frankel
Kinectics Of The Ground State Transformation In Fe(Ii) (N, N -Dicyclohexylthiourea)6(Cio4)2, R. Latorre, J. A. Costamagna, E. Frank, C. R. Abeledo, Richard B. Frankel
Physics
The high spin complex Fe(II) (N, N'-dicyclohexylthiourea)6(ClO4)6 exists in two forms which only differ in the distortion from octahedral symmetry of the environment of the Fe ion. Thermodynamic data for the transformation from one form to the other as obtained from Mössbauer spectroscopy are presented and a method to derive kinetic parameters is described.
On The Benefactive Feature In Transitivity, Dale Ellen Gaucas
On The Benefactive Feature In Transitivity, Dale Ellen Gaucas
Electrical Engineering and Computer Science - Technical Reports
An elaboration on the transitivity system network introduced by M. A. K. Halliday is developed. This extension consists of a separate feature system network for the participant role of “beneficiary”. The formulation of the proposed grammar rules to conjoin this network and Halliday's is facilitated by building up the transitivity network to describe "systemically” and uniquely each type of benefactive and range clause presented by Halliday. Systemic descriptions of these clauses are given as examples throughout the discussion.

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley
Reports
The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …
Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand
Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand
Reports
Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.
Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …
Esterase Activity In The Greater Wax Moth Larvae, Daphne Lin Pai
Esterase Activity In The Greater Wax Moth Larvae, Daphne Lin Pai
Masters Theses & Specialist Projects
Some properties of esterases of the greater wax moth larvae, Galleria mellonela (L.), were examined and the enzymes partially purified. Several buffer systems were tried and it was found that tris buffer was most suitable. The tris buffer resulted in less hydrolysis of the acetylsalicylic acid. Esterase activity was determined with acetylsalicylic acid in tris buffer, pH = 7.85, 0.05 M. The enzymes were partially purified by combination of acetone powder preparations, ammonium sulfate precipitations and gel filtration.
The ratio of esterase activity to protein content was increased 1.03 fold by acetone powder preparation and 1.5 fold by 70% ammonium …

Photochemistry Of Beta-Methyl-Beta-Nitrostyrene & Its Derivatives, Donald Tang
Photochemistry Of Beta-Methyl-Beta-Nitrostyrene & Its Derivatives, Donald Tang
Masters Theses & Specialist Projects
A series of β- methyl-β-nitrostyrenes have been synthesized and subjected to ultraviolet irradiation. A new technique has been developed for synthesis of 1-phenyl-1,2-propanedione-1-oxime and its derivatives by irradiation of the corresponding styrene. The yields of the oximes were almost quantitative [except 1-(p-nitrophynyl)-1,2-propanedione-1-oxime and 1-(m-nitrophenyl)-1,2-propanedione-1-oxime]. It has been found that irradiation of the appropriate styrene is a very simple, efficient, and general procedure for the synthesis of 1-phenyl-1,2-propanedione-1-oxime and a number of its derivatives. A number of derivatives of β- methyl-β-nitrostyrene (p-CH3, p-Ch30, p-Cl, p-No2, and m-NO2) were irradiated. It was found that …

Hydraulic And Flow Studies Related To Sediment Transport, Kentucky River, Kentucky, Bruce R. Moore, Michael R. Short, Thomas Wachs
KWRRI Research Reports
This study related the conditions of flow and channel shape to distribution of sediment types in the Kentucky River. Seven distinct types of sediment association were delineated and these have a regular pattern of distribution influenced by the presence of navigation locks and dams. The most suitable locations for commercial extraction of bed material were clearly indicated and the variations of sand size delineated by the study. The irregular discharge pattern of the stream indicates potential problems in the disposal of solid waste pollutants.
A remeasurement of the dredge hole in the Ohio River indicated a continuation of the same …
A Study Of Naturally Occurring Algicides Produced By Freshwater Algae, Denny O. Harris, Harry D. Caldwell
A Study Of Naturally Occurring Algicides Produced By Freshwater Algae, Denny O. Harris, Harry D. Caldwell
KWRRI Research Reports
The mode of action of the algicide produced by Pandorina morum was examined by exposing Volvox globator and isolates spinach chloroplasts to a partially purified algicide preparation. Oxygen evolution of Volvox, whole chloroplasts and broken chloroplasts (minus the Calvin cycle),was reduced indicating that the algicide inhibits the light reactions of photosynthesis. Oxygen evolution studies of other Volvocaceae confirmed the observation that Pandorina morum is not significantly influenced by its own inhibitor. Molecular weight approximation by gel filtration established that the inhibitor has a low molecular weight (probably below 100 mw). Field studies indicate that this algicide has tremendous potential as …

Reports
In 1969 the Virginia Institute of Marine Science published a report stating that although marshlands represented only one-half of one percent of the total area of the state, 95 percent of Virginia 's annual harvest of sport and commercial fisheries were dependent to some degree upon these valuable wetlands . The report went on to urge some form of public control over these vital areas in order to relieve some of the pressures created by dredging, filling, diking and bulkheading.
Recognizing the need to address this issue, the 1971 General Assembly passed House Joint Resolution Number 60, creating a Wetlands …

Repeatable Testing-A Tool For Learning Physics, David E. Golden, Robert Fuller, Donald D. Jensen
Robert G. Fuller Publications
Physics courses have traditionally used one-chance-only examinations as a probe to tell the professor how much physics each student has learned, with the result that physics examinations have been a common cause of anxiety among undergraduates. Repeatable equivalent examinations, on the other hand, offer an alternative testing procedure which underscores material not mastered on the first examination and then allows remedial study of this material for the next examination. Furthermore, the thought that it will be possible to have another try at the examination greatly decreases the anxiety associated with examinations. While repeatable examinations are routinely used in Keller-plan courses, …

Oer For Mixed Neutrons And Γ Rays, Robert Katz, S. C. Sharma
Robert Katz Publications
A formula for the OER in a mixed field of neutrons and gamma rays (Hall, 1972a; 1972b) is given .... Our results, calculated from track structure theory (Katz and Sharma, 1973) and secondary particle-energy spectra in tissue from these neutrons (Caswell and Coyne, 1973; Dennis, 1972) are within 5 per cent of the values of Omix found from the Hall formula, when that formula is supplied with calculated values of Rn, On, and Oγ, at appropriate survival levels. Our calculations suggest that the Hall formula may be used with confidence for neutrons of …
Molecular Model For Ice Clusters In A Supersaturated Vapor, Barbara N. Hale, P. L. M. Plummer
Molecular Model For Ice Clusters In A Supersaturated Vapor, Barbara N. Hale, P. L. M. Plummer
Physics Faculty Research & Creative Works
A molecular model previously applied to prenucleation water clusters is used to examine ice Ih, embryos. The canonical partition function is evaluated for clusters having from 6 to 64 water molecules. The intermolecular vibrational free energies are extrapolated to clusters containing up to 120 molecules and free energies of formation, nucleation rates, and critical supersaturation ratios are calculated and compared with experiment. For the clusters studied, the ice Ih structure appears to be much less stable at all temperatures than the more spherical clathratelike cluster.

Second-Order Raman Scattering In Alkali Fluoride Crystals, S. L. Cunningham, T. P. Sharma, Sitaram Jaswal, M. Hass, John R. Hardy
John R. Hardy Papers
We present theoretical and experimental second-order Raman spectra for NaF, KF, RbF, and CsF. The theoretical calculation follows the formalism of Born and Bradburn. For the lattice-dynamic calculation we use the deformation-dipole model and present comparisons with measured dispersion curves. For the polarizability calculation, we retain all eight first-neighbor and all thirty second-neighbor polarizability coefficients. We find that, in addition to all of the first-neighbor coefficients, only three of the second-neighbor coefficients are needed to obtain good agreement between the calculated and observed spectra both as regards peak positions and over-all shape. Comparison with other types of calculations are made.
