Dimethyl Sulfoxide Oxydation Of Hydroxy-Steroids And Studies On The Oxidation Of The 5’–Hydroxy Group Of Nucleosides, Carmen V. Zenarosa

Dissertations

Introduction

In our earlier work we demonstrated the usefulness of the acidcatalyzed reaction between N-(p -tolyl)diphenylketenimine (21) and dimethyl sulfoxide (DMSO) for the oxidation of secondary alcohols. This was exemplified by the oxidation of 2',3'-O-isopropylideneadenosine and other secondary alcohols.¹ We have now extended this procedure to the oxidation of hydroxy-steroids.

Alkynylamines or ynamines can be written in two resonance forms: R-C≡C-N R'₂ and R-C=C=NR'₂. Because of the close similarity between the latter structure and the structure of a ketenimine (R₂C=C=N-R') and the ability of sulfoxide-ketenimine to effect the oxidation of secondary alcohols, we …

Particle Tracks In Emulsion, Robert Katz, E. J. Kobetich

Robert Katz Publications

A new theory of track formation in emulsion accounts for the tracks of charged particles on the basis of a theory developed earlier for the response of biological molecules and NaI(T1) to energetic heavy ions. The probability that an emulsion grain will remain undeveloped when exposed to δ rays depositing a mean energy E is assumed to be e^-E/E₀ where E₀ is the dose at which l/e (37%) of the emulsion grains remain undeveloped, as in the one-or-more-hit cumulative Poisson distribution. The parameter E₀ incorporates variations in emulsion properties and processing conditions. Calculation of …

Nuclear Zeeman Effect In W182 In Iron, Richard B. Frankel, Y. Chow, L. Grodzins, J. Wulff

Physics

The Mössbauer effect in the 100-keV 2+→0+ transition in W182 was observed with dilute tungsten in iron alloy absorbers with concentrations from 0.5-5.0 at.%W at 4.2°K. From the Zeeman spectra in external longitudinal magnetic fields, the g factor of the first excited 2+ state was found to be 0.22±0.02, and the hyperfine field at tungsten nuclei in iron was found to be -708±25 kOe. The hyperfine interaction for Fe⁵⁷ in these alloys was also measured, and the results are compared with measurements on alloys of Fe with other 5d impurities and with neutron diffraction measurements.

Nmr Determination Of The Conduction-Electron Hyperfine Interaction In Crystalline Cdo, David C. Look

Physics Faculty Publications

Measurements of the Cd¹¹³ nuclear-spin-lattice relaxation time T₁ and Hall effect in crystalline CdO, a degenerate semiconductor, have yielded the contact hyperfine strength of the conduction electrons at the nuclei. The product T₁T=168 sec °K, independent of temperature T and frequency ν for T=1.4,4.2, and 77-350 °K, and for ν=2-10 MHz. Taking the carrier concentration N=2.6×10¹⁹ cm^-3 independent of temperature to within 3% at 4.2, 77, and 300°K, and using an effective electron mass m_e^*=0.2m_e, we calculate an averaged electron probability density at the nucleus, 〈|φ_F(0)|^{2 …}

Peracid Oxidation Of 3-Phenylindene, Christopher Peter Johnson

Master's Theses

Indene oxide (indan, 1,2-epoxy; indene 2,3-oxid is first recorded in the literature in 1919. This compound was formed in practically quantitative yield by the treatment of indene bromo­ hydrin in ether with powdered potassium hydroxide. At this time Van Loon also reported the preparation of indene oxide by mechanical shaking of an anhydrous, ethere!al solution of the bromohydrin with finely powdered potassium hydroxide. The desired product was obtained in a 92-97% yield by this method. Indene oxide has been prepared in a similar manner from trans-2-chloro-l-indanol by treatment "with soda," distillation of the acetone in vacuo after 15 hours, and …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Located in the west central portion of Clark County, Nevada, the Spring Mountain Range borders the western edge of the Las Vegas Valley. Within the mountain range, a fault block, there are several canyons whose geomorphic history is closely related to the geomorphic history of the major alluvial fans which flank the mountains. Lee Canyon, which is the study area is one of these canyons. In Lee Canyon is preserved a complex canyon fill which has been subjected to several periods of down-cutting and valley-widening. The details of the canyon's geomorphic history recorded by filling and fill removal has not …

A Study To Discover The Supply And Demand Of Industrial Arts Teachers In Utah, L. Gyle Hollingsworth

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

With the increase in population and corresponding growth in school enrollment in the state of Utah, the need for more adequate educational facilities becomes ever more apparent. New schools will have to be built and older ones enlarged in order to accommodate the increasing enrollment and need. As a natural consequence , additional teachers will be needed to fill the positions made available by the expansion of the present educational facilities. This requirement will be supplemented by the need for maintaining the present level of teaching staff in view of the outflow of teachers from the system, some through retirement, …

Stochastic Processes Model And Its Application In Operations Research, Chun Yuan Hsu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Just as the probability theory is regarded as the study of mathematical models of random phenomena, the theory of stochastic processes plays an important role in the investigation of random phenomena depending on time. A random phenomenon that arises through a process which is developing in time and controlled by some probability law is called a stochastic process. Thus, stochastic processes can be referred to as the dynamic part of the probability theory. We will now give a formal definition of a stochastic process.

Let T be a set which is called the index set (thought of as time), then, …

The Hyrum And Beirdneau Formations Of North-Central Utah And Southeastern Idaho, James F. Eliason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Hyrum and Beirdneau Formations of North-central Utah and Southeastern Idaho represent rocks of late Middle Devonian (Givetian) to upper Upper Devonian (Famennian) age. They are disconformably underlain by the Early Devonian Water Canyon Formation in most cases and disconformably overlain by the Devonian-Mississippian Leatham Formation or the Mississippian Lodgepole Formation.

The Hyrum Formation is divided into five members based on lithology and color changes. The five members are: (1) Samaria, (2) Lower Dolomite, (3) Lower Carbonate-detritus, (4) Upper Dolomite, and (5) Upper Carbonate-detritus Members. The Samaria Member is the only fossiliferous unit within the Hyrum Formation.

Analysis Of Contingency Tables, James Joseph Biundo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two methods of analyzing multi-dimensional frequency data are detailed.

The Second Order Exponential (SOE) model is applicable for dichotomous classifications. The distribution has two sets of parameters, ϴ_i's and ϴ_j's. The ϴ_i's are interpreted as the log of the odds of the marginal probabilities if no two factor relationships exist. Or if all ϴ_ij are not zero, then the ϴ_i's are analogous to a main effect in a 2^m factorial analysis, (m = number of factors or classifications). The ϴ_if's may be interpreted as a measure and direction …

Lattice Dynamics And Second-Order Raman Spectrum Of Naf, John R. Hardy, A. M. Karo, I. W. Morrison, C. T. Sennett, J. P. Russell

John R. Hardy Papers

The second-order Raman spectrum of NaF has been measured using an argon laser source. For a light beam incident along the [010] direction, polarized along the [001] direction, and viewed along the [100] direction, the scattered radiation is almost completely polarized. It is shown theoretically that it is possible to account for the polarization and the detailed shape of the observed spectrum within the experimental resolution using a Raman polarizability tensor whose second derivatives with respect to nuclear displacements depend only on the positions of first neighbors in the crystal, provided one uses the phonon frequencies derived from a deformation …

Multiple Charge States, Hyperfine Interactions, And Relaxation Processes Of Fe In 57Co-Doped Mgo, J. Chappert, Richard B. Frankel, A. Misetich, N. A. Blum

Physics

The Mössbauer spectra of cobalt-57-doped magnesium oxide have been studied between 1.3 and 550°K in external magnetic fields of up to 135 kOe for both single-crystal and polycrystalline samples. At room temperature and zero external magnetic field, the velocity spectrum is composed of three single lines, attributed to monovalent, divalent, and trivalent iron. In certain samples, for T2+ line undergoes a transition to a quadrupole doublet with a splitting ΔE_Q=0.30±0.02 mm/sec, while in certain other samples, annealed differently, no doublet is observed down to 1.5°K. The first case is in quantitative agreement with a random-strain model …

Quasifree Knockout Of Deuterons In The ⁶Li(Α,Αd)⁴He Reaction At 23.6 Mev, K. Bähr, T. Becker, Oleksa-Myron Bilaniuk, R. Jahr

Physics & Astronomy Faculty Works

α−d correlations in quasi-elastic scattering of 23.6-MeV α particles on the deuteron cluster of the ⁶Li target were measured in and off the principal reaction plane. Despite the low c.m. energy of 14.2 MeV, the impulse approximation provides a reasonable description of the quasifree process. Computations were based on the asymptotic α−d S-state wave function and on the cluster-model wave function of ⁶Li. Insensitivity of the fits to the details of the ⁶Li cluster-model wave function indicates an extreme surface reaction mechanism. The full width at half-maximum of the spectator momentum distribution was found to be 48±6 MeV/c. By comparing …
