Towards Direct Writing Of 3-D Photonic Circuits Using Ultrafast Lasers, Arnaud Zoubir

Electronic Theses and Dissertations

The advent of ultrafast lasers has enabled micromachining schemes that cannot be achieved by other current techniques. Laser direct writing has emerged as one of the possible routes for fabrication of optical waveguides in transparent materials. In this thesis, the advantages and limitations of this technique are explored. Two extended-cavity ultrafast lasers were built and characterized as the laser sources for this study, with improved performance over existing systems. Waveguides are fabricated in oxide glass, chalcogenide glass, and polymers, these being the three major classes of materials for the telecommunication industry. Standard waveguide metrology is performed on the fabricated waveguides, …

Stage-Specific And Interactive Effects Of Sedimentation And Trout On A Headwater Stream Salamander, Winsor H. Lowe, Keith H. Nislow, Douglas T. Bolger

Dartmouth Scholarship

In species with complex life cycles, stage-specific effects of environmental conditions combine with factors regulating stage-specific recruitment to determine population-level response to habitat disturbance. The abundance of the stream salamander Gyrinophilus porphyriticus(Plethodontidae) is negatively related to both logging-associated sedimentation and brook trout (Salvelinus fontinalis) in headwater streams throughout New Hampshire, USA. To understand the mechanisms underlying these patterns, we investigated stage-specific and interactive effects of sedimentation and brook trout on G. porphyriticus. We conducted quantitative surveys of salamanders, brook trout, and substrate embeddedness in 15 first-order streams and used a controlled experiment to test the direct and interactive effects of …

Multi-Channel Fetal Magnetocardiographic Signal Seperation For Analysis Of Heart Rate Variability, Joshua Quaid Campbell

Theses and Dissertations

Objective: The objectives were to implement signal-processing techniques to separate the fetal magnetocardiogram (FMCG), as collected by SQUID (Superconducting QUantum Interference Device) gradiometers, from mixtures of maternal and fetal biomagnetic signals recorded during the antepartum period and to develop a database of normal FMCG values of the fetal cardiac time intervals and heart rate variability measures. Materials and Methods: The research was performed in three phases: 1) Independent component analysis (ICA), nonlinear filtering techniques, and orthogonal projection methods were optimized enabling the FMCG to be processed using traditional signal analysis techniques; 2) The cardiac time intervals and heart rate variability …

An Analysis Of Mentorship In Michigan Police Agencies, Jeffrey G. Swanson

Masters Theses

The purpose of this research is to investigate how newer police officers are familiarized into their agency with respect to the manner in which they were trained and mentored. The concept of mentoring programs has been highly successful in the private and business sectors for many years. Since the concept of formal mentoring programs in law enforcement is largely limited to date, this study incorporates research in several other disciplines, to determine if there may be a corollary regarding law enforcement and other disciplines, and if so, to what degree mentoring exists among patrol officers. A survey was distributed to …

Probing Molecular Free Energy Landscapes By Periodic Loading, Oliver Braun, Andreas Hanke, Udo Seifert

Physics & Astronomy Faculty Publications

Single molecule pulling experiments provide information about interactions in biomolecules that cannot be obtained by any other method. However, the reconstruction of the molecule’s free energy profile from the experimental data is still a challenge, in particular, for the unstable barrier regions. We propose a new method for obtaining the full profile by introducing a periodic ramp and using Jarzynski’s relation for obtaining equilibrium quantities from nonequilibrium data. Our simulated experiments show that this method delivers significant more accurate data than previous methods, under the constraint of equal experimental effort.

Studies Of Ergot Alkaloid Biosynthesis Genes In Clavicipitaceous Fungi, Caroline Machado

University of Kentucky Doctoral Dissertations

Neotyphodium species, endophytic fungi associated with cool-season grasses, enhance host fitness and stress tolerance, but also produce biologically active alkaloids including ergot alkaloids associated with fescue toxicosis in grazing animals. One approach to reduce fescue toxicosis is to manipulate genes in the ergot alkaloid pathway. The gene, dmaW, encoding the first pathway-specific step in ergot alkaloid biosynthesis, was cloned previously from Claviceps spp. and its function was demonstrated by expression in yeast. Putative homologs have been cloned from Neotyphodium coenophialum (from tall fescue) and Neotyphodium sp. Lp1 (from perennial ryegrass). In order to confirm the function of dmaW in ergot …

Isolation And Characterization Of A Second Protein L-Isoaspartyl Methyltransferase Gene In Arabidopsis Thaliana, Qilong Xu

University of Kentucky Doctoral Dissertations

Conversion of aspartate and asparagine residues to isoaspartate is a prevalent covalent protein modification in cells. The accumulation of these altered residues can lead to the loss of protein function and the consequent loss of cellular function. The L-ISOASPARTATE METHYLTRANSFERASE (EC 2.1.1.77) (PIMT) iteratively methylates abnormal isoaspartyl residues leading to conversion to L-aspartate, thereby mitigating the injurious effects of aging. Arabidopsis thaliana is unique among eukaryotes studied to date in that it possesses two genes (At3g48330 (PIMT1) and At5g50240 (PIMT2)) encoding PIMT. The PIMT2 gene exhibits a complex transcriptional control involving different transcriptional initiation sites and 5'- and 3'- alternative …

"There is something ludicrous in philosophical discourse," Michel Foucault writes, "when it tries, from the outside, to dictate to others, to tell them where their truth is and how to find it... " (Foucault 1985, 9). In our age of moral relativism and multiculturalism, it is easy to hear in this sentence a simple condemnation of intellectuals who pose as authorities on questions of belief, and it is all too easy to agree; yes, of course, we ought not tell other people what to think. But given the issues, directions, and investments of Foucault's work, especially in The Use of …

The Virulence Of Blackthink™ And How Its Threat Of Ostracism Shackles Those Deemed Not Black Enough, Kimberly Jade Norwood

Scholarship@WashULaw

This Article explores a non-traditional form of discrimination based on color. In the United States we are accustomed to hearing about discrimination in the context of historic injustices the black community has faced for no other reason but that they were born black or African-American. This Article deals with another form of discrimination against black people based on skin color: discrimination based on not being black enough. Blacks who do not fit a particular expectation about what it means to be black are often marginalized or even ostracized from their communities. They are vilified as Sells-Outs, Oreos and Uncle Toms. …

Predicting Phenological Development In Winter Wheat, Qingwu Xue, Albert Weiss, P. Stephen Baenziger

Department of Agronomy and Horticulture: Faculty Publications

Accurate prediction of phenological development is important in the winter wheat Triticum aestivum agroecosystem. From a practical perspective, applications of pesticides and fertilizers are carried out at specific phenological stages. In crop-simulation modeling, the prediction of yield components (kernel number and kernel weight) and wheat-grain yield relies on accurate prediction of phenology. In this study, a nonlinear multiplicative model by Wang & Engel (WE) for predicting phenological development in differing winter wheat cultivars was evaluated using data from a 3 yr field experiment. In the vegetative phase (emergence to anthesis) the daily development rate (r) was simulated based on the …

An Investigation For Genetic Susceptibility To Type 1 Diabetes Mellitus And Its Microvascular Complications, D.M. Hegazy

School of Biomedical Sciences Theses

Long-term exposure to diabetes mellitus is associated with metabolic abnormalities such as chronic hyperglycemia and redox imbalance. Uncontrolled hyperglycaemia and genetic factors are implicated in the pathogenesis of diabetic microvascular diseases. Genetic mutation through the genes coding for enzymes involved in glucose metabolism and immuno-regulatory mechanisms may contribute to the susceptibility to type I diabetes mellitus (TIDM) and its chronic microvascular diseases. Previous studies have shown that the transcription factor, nuclear factor kappa 8 (NFκB) and heat shock proteins (HSPs) are two redox-sensitive cellular responses of most immune and inflammatory diseases including diabetes and its late vascular complications. NFκB promotes …

From Cannibalism To Empowerment: An Analects-Inspired Attempt To Balance Community And Liberty, Sor-Hoon Tan

Research Collection School of Social Sciences

The Confucian tradition has often been credited with a strong allegiance to the value of community. It recognizes that certain goods might be attained through special forms of human association, but not by any solitary individual. Are such community goods attained at the expense of the liberty of individual members? Philosophers have struggled with the tension between liberty and community since the dawn of Western philosophy. Aristotle complained about the false idea of liberty as "doing what one likes," which is contradictory to the true interests of the polis.2 Such lib- erty, or rather license, is undoubtedly detrimental to any …

Zebra Mussel And Fouling Problems In The Euphrates Basin, Alaeddi̇n Bobat, Mehmet Oğuz Hengi̇rmen, Walter Zapletal

Turkish Journal of Zoology

The Zebra mussel, Dreissena polymorpha Pallas, is one of the most important fouling organisms in freshwater ecosystems. Infestations by Zebra mussels have caused chronic problems in both raw water(incoming water into facilities) intakes and man-made structures such as water treatment facilities, power plants and industrial facilities. In the mid-1980s, this pest, a species nonindigenous to North American freshwaters, was introduced into the Great Lakes of North America. This introduction probably occurred by means of the ballast water of a transoceanic ship, and concern has focused again on this nuisance and its impact. Recently, the Zebra mussel, a species native to …

Morphological and biological data as well as missing pieces of information about the species were sought to be completed with the addition of a large number of new localities. Moreover, the data obtained were compared with those in the relevant literature in an attempt to shed light on the taxonomical status of the species.

Faunistic And Morphological Studies On Ciliates (Protozoa, Ciliophora) From A Small Pond, With Responses Of Ciliate Populations To Changing Environmental Conditions, Naci̇ye Gülkiz Şenler, İsmai̇l Yildiz

Turkish Journal of Zoology

Sixty-nine ciliate species were identified in 19 samples from a small pond covered by Lemna minor in Van, Turkey. Statistical analysis was employed to examine the relationships between ciliates and the physical and biological parameters. Total ciliate abundance appears to be related mainly with physical and biological factors such as the dissolved oxygen in the bottom layer and the volume of Lemna and temperature in the surface layer. Some species were investigated in detail using live observation, silver impregnation, and morphometry.
