Effect Of Temperature On Retention Of Enantiomers Of Β-Methyl Amino Acids On A Teicoplanin Chiral Stationary Phase, Antal Péter, Gabriella Török, Daniel W. Armstrong, Géza Tóth, Dirk Tourwé Dec 1998

Effect Of Temperature On Retention Of Enantiomers Of Β-Methyl Amino Acids On A Teicoplanin Chiral Stationary Phase, Antal Péter, Gabriella Török, Daniel W. Armstrong, Géza Tóth, Dirk Tourwé

Chemistry Faculty Research & Creative Works

The isocratic retention of enantiomers of β-methyl amino acids (β-methyltyrosine, β-methylphenylalanine, β-methyltryptophan and β-methyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) was studied on a teicoplanin-containing chiral stationary phase at different temperatures and at different mobile phase compositions, using the reversed-phase mode. With variation of both mobile phase composition and temperature, almost baseline separations could be achieved for all four enantiomers of sterically hindered amino acids. The retention factors and selectivity factors for the enantiomers of all investigated compounds decreased with increasing temperature. The natural logarithms of the retention factors (ln k) of the investigated compounds depended linearly on the inverse of temperature (1/T). van 't …

Experimental Observation Of Relativistic Nonlinear Thomson Scattering, Szu-Yuan Chen, Anatoly Maksimchuk, Donald Umstadter Dec 1998

Experimental Observation Of Relativistic Nonlinear Thomson Scattering, Szu-Yuan Chen, Anatoly Maksimchuk, Donald Umstadter

Donald Umstadter Publications

Classical Thomson scattering—the scattering of low-intensity light by electrons—is a linear process, in that it does not change the frequency of the radiation; moreover, the magnetic-field component of light is not involved. But if the light intensity is extremely high (~1018 Wcm–2), the electrons oscillate during the scattering process with velocities approaching the speed of light. In this relativistic regime, the effect of the magnetic and electric fields on the electron motion should become comparable, and the effective electron mass will increase. Consequently, electrons in such high fields are predicted to quiver nonlinearly, moving in figure-eight patterns …

Grass Shrimp Palaemonetes Pugio Predation On Sediment- And Stem-Dwelling Meiofauna: Field And Laboratory Experiments, Christopher S. Gregg, John W. Fleeger Dec 1998

Grass Shrimp Palaemonetes Pugio Predation On Sediment- And Stem-Dwelling Meiofauna: Field And Laboratory Experiments, Christopher S. Gregg, John W. Fleeger

Faculty Publications

Field and laboratory experiments were conducted to clarify the predatory role of Palaemonetes pugio Holthius in salt-marsh benthic communities. Field experiments (cage enclosures using P. pugio as a predator) were conducted on unvegetated mudflat and vegetated-marsh sites. Neither sediment- or stem-dwelling meiofaunal abundances were significantly impacted. Laboratory experiments measured the functional response of P. pugio feeding on suspended harpacticoid copepods, tested the efficiency of P. pugio feeding on harpacticoids in sediments, and measured the predation rate of P. pugio on stem-dwelling meiofauna. Grass shrimp feeding rate on suspended copepods followed a type II functional response, increasing with increasing prey density …

Relativistic Nonlinear Optics, Phillip F. Schewe, Ben Stein, Donald P. Umstadter Dec 1998

Relativistic Nonlinear Optics, Phillip F. Schewe, Ben Stein, Donald P. Umstadter

Donald Umstadter Publications

Laser light is a convenient way of transporting both electric and magnetic fields. When an electron encounters light, however, it is usually the electric field that does the talking; the magnetic part of light is less influential since its effect on the electron is proportional to the electron's speed as a fraction of the speed of light (c). In new experiments at the University of Michigan this is all changed since the intensity of the laser light used is so great (a terawatt of power, compared to a milliwatt for a laser in a CD player) that the electrons in …

Heterogeneity And Bias In Abundance Estimates Of Outmigrating Chinook Salmon In The Chena River, Alaska, Ted M. Lambert Dec 1998

Heterogeneity And Bias In Abundance Estimates Of Outmigrating Chinook Salmon In The Chena River, Alaska, Ted M. Lambert

Fisheries

The objective was to examine bias due to heterogeneity in capture probability (p) in an abundance estimate for chinook salmon (Oncorhynchus tschawytscha) outmigrants in the Chena River, Alaska. A higher proportion of day-marked fish (21 / 636 = 0.0330) compared to night-marked fish (17 / 1724 = 0.0098; p<0.0001, α=0.05) was recaptured at the lower site in a Cormack-Jolly-Seber experiment with upper, middle and lower sites. Heterogeneity was also likely at the middle site between upper site-marked and unmarked fish. Simulations with heterogeneity confined to the middle and lower sites (i.e., due to inadequate mixing) caused small bias (<2.5%) in the upper site abundance estimate. With heterogeneity at all three sites (a subpopulation effect), the upper site estimate had 22.9% to 29.3% negative bias. Because heterogeneity observed in the Chena was probably due to inadequate mixing (related to daytime trap evasion), bias in the upper site estimate was probably small.

Lake Productivity Indices As Estimators Of Carrying Capacity For Burbot And Northern Pike In Interior Alaska, Thomas David Simpson Dec 1998

Lake Productivity Indices As Estimators Of Carrying Capacity For Burbot And Northern Pike In Interior Alaska, Thomas David Simpson

Fisheries

Two Alaska sport fish species, burbot and northern pike, were used to test the ability to estimate carrying capacity of fishes based on biotic and abiotic indices of lake productivity. Understanding the quantitative relationships between the potential fish productivity of freshwater lakes and physical, biological, or chemical characteristics could provide models sufficient for calculating a timely prediction of carrying capacity to evaluate the population status. This would provide a technique for allocating limited resources for fishery stock assessment as an aide in resource management of sport fisheries. The lakes covered in the study lie in an area spanning West 151°--142°/North …

The Effect Of Particle Properties On The Flow Characteristics Of Electrophotographic Powders, Joseph Pedano Dec 1998

The Effect Of Particle Properties On The Flow Characteristics Of Electrophotographic Powders, Joseph Pedano

Theses and Dissertations

The effect of particle size on the flow characteristics and tribo-electrical charge of dry electrophotographic (toner) powders was investigated. Toner samples, consisting of the same base formulation, but differing in particle size were prepared and studied using commercially available processing and analytical equipment. The effect of post-blending fumed silica into the toner was also investigated as part of this work. The results indicate that toner particle size has a strong effect on toner flow characteristics. The flowability measurements that were most affected by the particle size were the cohesiveness and compressibility properties of the toner powders. The data showed that …

Long-Wavelength Collective Excitations In A Two-Dimensional Spin-Polarized Electron Gas: A Phenomenological Theory, D C. Marinescu, J J. Quinn Dec 1998

Long-Wavelength Collective Excitations In A Two-Dimensional Spin-Polarized Electron Gas: A Phenomenological Theory, D C. Marinescu, J J. Quinn

Publications

The dispersion relations of the collective excitations induced in a 2D spin-polarized electron gas are derived within the framework of the Landau-Silin theory applied to a two-component Fermi liquid. The quasiparticle interaction is described by spin-dependent coefficients, which are parametric functions of the initial degree of polarization. The motion of the low-energy excitations satisfies a semiclassical transport equation solved consistently with the Maxwell equations for the electromagnetic field produced by spin and charge fluctuations. The long-wavelength limit of the self-sustained oscillations is analyzed as a function of the initial degree of polarization of the system, preset by a dc magnetic …

On The Basic Representation Theorem For Convex Domination Of Measures, J. Elton, Theodore P. Hill Dec 1998

On The Basic Representation Theorem For Convex Domination Of Measures, J. Elton, Theodore P. Hill

Research Scholars in Residence

A direct, constructive proof is given for the basic representation theorem for convex domination of measures. The proof is given in the finitistic case (purely atomic measures with a finite number of atoms), and a simple argument is then given to extend this result to the general case, including both probability measures and finite Borel measures on infinite-dimensional spaces. The infinite-dimensional case follows quickly from the finite-dimensional case with the use of the approximation property.

Parental Grief Responses To Perinatal Loss, Lisa M. Peacock Dec 1998

Parental Grief Responses To Perinatal Loss, Lisa M. Peacock

Masters Theses

An exploratory, descriptive design was used to examine parental grief and coping responses to perinatal loss. Florence Selder's Life Transition Theory (1989) was used as the conceptual fiamework. A survey approach was used for data collection. This included basic demographic questions, the Perinatal Bereavement Scale and the Jalowiec Coping Scale. A convenience sample was obtained, consisting of 24 women and 6 men in northern Michigan communities who had experienced a perinatal loss at some time in the past. Data were collected by an anonymous mailed survey. The results of the study revealed that all parents in this sample did exhibit …

Events With A Rapidity Gap Between Jets In P̅P Collisions At √S = 630 Gev, F. Abe, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration Dec 1998

Events With A Rapidity Gap Between Jets In P̅P Collisions At √S = 630 Gev, F. Abe, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We report a measurement of the fraction of dijet events with a rapidity gap between jets produced by color-singlet exchange in p̅p collisions at √s =630 GeV at the Fermilab Tevatron. In events with two jets of transverse energy ETjet > 8 GeV, pseudorapidity in the range 1.8 <|ηjet | < 3.5 and η1 η2 < 0, the color-singlet exchange fraction is found to be R=[2.7 ± 0.7(stat) ± 0.6(syst)]%. Comparisons are made with results obtained at √s =1800 GeV and with theoretical expectations.
