Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

Creator:: Sturmer, David Michael
Abstract:: New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

Alternating current and voltage profiles on compensated high-voltage underground power cables

Creator:: Hirakami, Michael
Abstract:: The utilization of extra-high-voltage underground power cables over distances greater than 100 miles presents serious problems relative to the voltage and current limits of such cables. These problems are directly associated with the fixed amount of capacitance inherent in long cable lines. As a result, large charging currents are characteristic...

Physical factors affecting longevity and germination of seed of Western dwarfmistletoe (Arceuthobium campylopodum Engelm. f. campylopodum)

Creator:: Beckman, Kent Mardsen
Abstract:: Longevity and germination of seed of western dwarfmistletoe (Arceuthobium campylopodum Engelm. f. campylopodum) of ponderosa pine (Pinus ponderosa Laws.) was investigated to determine: 1) the influence of humidity and temperature on seed viability and deterioration during storage; 2) the physiology of seed dormancy; 3) the composition of seed reserve food...

Purification and properties of the polygalacturonases produced by Fusarium oxysporum f. sp. lycopersici

Creator:: Harman, Gary Elvan, 1944-
Abstract:: This study was undertaken to determine the sorts of polygalacturonases present in the culture filtrate of Fusarium oxysporum f. sp. lycopersici, to purify and characterize these enzymes, and to study any complexes that may form between polygalacturonase and carbohydrate not degraded by the enzyme. The polygalacturonase in culture filtrate consists...

High-efficiency radio-frequency power amplifiers

Creator:: Ewing, Gerald Dean
Abstract:: This dissertation describes a new radio-frequency power-amplifier circuit and mode of operation that exceeds the efficiency of the conventional class C amplifier in the low and medium h-f range. It will be found useful in applications where linearity between the input and output are not required, as in all applications...

The maximum principle and its application to industrial engineering problems

Creator:: Kanbe, Kenji
Abstract:: The maximum principle developed by the Russian mathematician, L.S. Pontryagin is considered to be one of the most significant contributions to the recent advances in mathematical optimization techniques. Unfortunately, most of the published literature on the application of the maximum principle is in the field of control system design, and...

The design of ultrasonic waveguide system for time delay applications

Creator:: Davis, Thomas James
Abstract:: A waveform-preserving, variable time-delay system capable of several milliseconds delay is described in this thesis. These considerably long delays are achieved by judicious use of the relatively low sonic velocity of gases. Initial system design criteria specified a time delay of ten milliseconds and a signal bandwidth of 0-10 KC....

A sampling criterion enabling signal reconstruction with specified limit error

Creator:: Wilkins, Dennis James
Abstract:: A sampling criterion which provides a numerical relationship between sampling rate and worst-case peak error for linear interpolation of sample points is presented. The criterion, based upon the second derivative of a waveform, is derived, its properties are observed for a sine wave, and its applicability to complex signals is...

An electrolytic tank analog for myoelectric surface potentials

Creator:: Churchill, Frank Tefft
Abstract:: It was observed that certain myoelectric surface potentials are of a pulse nature. The pulses have nearly the same exact waveshape, but are asynchronously repetitive. Physiological evidence indicated that myoelectric pulses are concurrent with the activity of a small unit of organized muscle fibres (motor unit). The electrical activity of...

Determination of food carbon assimilation in copepods

Creator:: O'Connors, Harold Blane Jr
Abstract:: A method for measuring food carbon assimilation in the copepod Calanus finmarchicus was developed, using the diatom Ditylum brightwelli as food. The amount of particulate food carbon ingested was determined as the difference between CHN analyzer analyses for particulate food carbon of pre- and post-grazed food suspensions. The fraction of...

Reactions of organoboranes

Creator:: Thompson, Thomas Myron
Abstract:: An examination was made of some reactions involving a transfer of carbon from boron to carbon. In the case of the reaction of a C[subscript n] alkylorganoborane with dichlorocarbene the intermediate was a C[subscript n]₊₁ chloroalkylorganoborane. Oxidation of this intermediate yielded an homologous acid (33%) and the usual alcohol (66%)....
