Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence Apr 1973

Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence

Theses and Dissertations

Purified Bacillus subtilis DNA taken up by one-day-old barley embryos and permanently fixed within the barley cell is shown to have maintained its biological activity in B. subtilis transformation. Cesuim chloride density gradient centrifugation of DNA isolated from the roots of barley embryos after the uptake and incorporation of radioactive, bromouracil-labelled B. subtilis DNA indicates the presence of the bacterial DNA in several discreet bands of well-defined density, whose density is changed by sonication. These preliminary findings concerning the fate of bacterial DNA taken up by barley roots are discussed in terms of the recombination model of Ledoux and Huart …

The Purification And Characterization Of Cytochrome B₅ From Porcine Kidney, M. Dean Klingler Apr 1973

The Purification And Characterization Of Cytochrome B₅ From Porcine Kidney, M. Dean Klingler

Theses and Dissertations

A soluble form of cytochrome b_5, with a 413/280 nm ratio of nearly unity, has been isolated and purified from porcine kidney using fractional precipitation, ion exchange resins, and gel filtration procedures. The cytochrome b_5 shows heat stability up to 50° and is stable in the pH range 6.0 to 8.5. The oxidized protein exhibits an absorption maximum at 413 nm, while the reduced form shows three peaks: 423, 526, 556 nm. Molecular weight determinations have given variable results, suggesting the possibility of a polymer composed of four and eight units of a 13,500 molecular weight protomer. This study has …

|Ni.|Pa Calorimetric Study Of The Heat Of Ionization Of Water At 10 And 40°C, And,|Nii.|Pa Calorimetric Determination Of The Heat Of Reaction Of Tris (Hydroxymethyl) Aminomethane (Tham) With Hydrochloric Acid In Aqueous Solution At 10, 25, And 40°C, Griffith Lyn Kimball

Theses and Dissertations

The heat of neutralization, ΔH_-N, of perchloric acid with sodium hydroxide has been determined at 10 and 40° in a low ionic strength, μ, region using a nonisothermal, constant-temperature-environment solution calorimeter. Correction of the data to infinite dilution by extrapolation of a plot of ΔH_-N vs μ^0.5 gives values at zero ionic strength for the heat of ionization of water of 14.216 and 12.695 kcal/mole, respectively, at 10 and 40° . The data are correlated with those of earlier workers to give an equation allowing the calculation of the heat of ionization of water at zero ionic strength over the …

⁷Li(D,P)⁸Li Excitation Function :|Be[Subscript D] = 0.623 Mev To 1.968 Mev, Albert E. Schilling Apr 1973

⁷Li(D,P)⁸Li Excitation Function :|Be[Subscript D] = 0.623 Mev To 1.968 Mev, Albert E. Schilling

Theses and Dissertations

In this study the excitation function for the ^7Li(d,p)^8Li reaction is determined at incident deuteron energies ranging from 0.623MeV to 1.968MeV by counting the delayed alpha-particles as a result of the ^8Li beta decay. This excitation function reveals resonances at 0.777±0.012MeV and 1.031±0.015MeV with cross sections of 202±9mb and 188±8mb respectively. The uncertainty in the cross section values was due to three independent sources of error within this experiment, the solid angle, the ^8Li half-life, and the target (LiF) thickness. The uncertainty in the energy values was determined from an energy calibration of the accelerator used in this study. Resonances …

Transient Convective Heat Transfer In Closed Containers During And After Gas Injection, Jennings Donell Means Apr 1973

Transient Convective Heat Transfer In Closed Containers During And After Gas Injection, Jennings Donell Means

Theses and Dissertations

This dissertation presents experimental data correlations for the spatially - averaged convective heat transfer coefficient for thin walled closed containers during and after gas injection. The different modes of heat transfer were identified, and correlations were made for each. Correlations are presented for the injection period, post-top injection, post-bottom injection, post- tangential, post-radial injection, and post-ejection heat transfer for various tank geometries. Of special significance are the very high heat transfer rates that were shown to be present in some cases immediately after injection. Heat transfer rates were shown to be, for a short period, up to almost two orders …

The Design And Analysis Of An Electro-Pneumatic Signal Converter, Richard K. Thornton Apr 1973

The Design And Analysis Of An Electro-Pneumatic Signal Converter, Richard K. Thornton

Theses and Dissertations

In the field of process control it is desirable to study dynamic characteristics such as frequency response and distortion when determining just how equipment is to be controlled. Pneumatic controllers, transmitters, control valves, etc., all have dynamic behaviors which can be expressed mathematically as transfer functions. Each component plays an important role in determining the entire system behavior. Frequency response is one technique used in developing a component’s transfer function. By driving a device with a sinusoidal signal of fixed amplitude and frequency the output amplitude and phase shift are measured and compared with that of the input. Varying the …

Reactions Of N₂F₄ And Sf₆ With H₂ Induced By Co₂ Laser Pulses And By Electrical Discharge, John Leslie Lyman Apr 1973

Reactions Of N₂F₄ And Sf₆ With H₂ Induced By Co₂ Laser Pulses And By Electrical Discharge, John Leslie Lyman

Theses and Dissertations

A high power pulsed CO_2 laser was used to induce reactions in gas mixtures containing either N_2F_4 or SF_6. The rate of laser induced dissociation of N_2F_4 to NF_2 was as much as 1000 times faster than the thermal rate, and the rate law was of lower order than the thermal, bimolecular rate law. Explosion threshold and induction time data were obtained for butene stabilized mixtures of N_2F_4 and H_2. HF laser gain was observed during the first few microseconds of CO_2 laser pulse, but it was strongly quenched by the explosion. The laser driven reaction of SF_6 with H_2 …

Finite Conductance Element Method Of Conduction Heat Transfer, E. Clark Lemmon Apr 1973

Finite Conductance Element Method Of Conduction Heat Transfer, E. Clark Lemmon

Theses and Dissertations

One of the basic goals in engineering is to formulate models which will provide a means for analytically predicting observed phenomenon. For some time, the partial differential equations describing the steady state and transient conduction of heat within a solid have been available. However, the straight forward use of these equations is often restricted due to the surface geometry of the solid. If the surface geometry is at all irregular, exact solutions will in general not exist. In that case, a solution is sought by some approximate numerical technique. The two techniques most often used are the finite difference method …

An Aerodynamic Investigation Of The Causes Of Overhead Electrical Transmission Line Gallop, Eric Nathan Skousen Apr 1973

An Aerodynamic Investigation Of The Causes Of Overhead Electrical Transmission Line Gallop, Eric Nathan Skousen

Theses and Dissertations

Overhead electrical transmission lines vibrate due to the action of a prevailing wind. These cable vibrations can be classified into two categories— high-frequency and low-frequency. The high-frequency vibrations, "aeolian" vibrations or "singing wires," is a low-amplitude phenomenon. It has been largely controlled with the use of various mechanical dampers [l, 2],

Incidence Of Spotted Fever In Wood Ticks Of Utah Recreational Sites, C. Selby Herrin Mar 1973

Incidence Of Spotted Fever In Wood Ticks Of Utah Recreational Sites, C. Selby Herrin

Great Basin Naturalist

In 1964, 135 male and 223 female Dermacentor andersoni Stiles were collected at 48 national forest recreation areas in Utah. Using guinea pigs immunological tests were performed on each of 62 samples to determine the presence of the Rocky Mountain spotted fever rickettsia. Thirteen of the samples (21 percent) were positive. These 13 samples contained 35 males and 34 females yielding an infection rate of at least 3.6 percent, assuming one infected tick was in each sample.

The Mysteries Of God, Noel B. Reynolds Mar 1973

The Mysteries Of God, Noel B. Reynolds

Faculty Publications

LDS discourse commonly uses the term mysteries to refer to truths that we don’t know or shouldn’t worry about. But the scriptures—and particularly the Book of Mormon—speak of the mysteries very positively, as something we should seek to know. The scriptural terminology appears to refer to the things of God that the faithful come to know—things that nonbelievers never understand.
