Correlations Between Liquid Crystal Director Reorientation And Optical Response Time Of A Homeotropic Cell, Haiying Wang, Thomas X. Wu, Xinyu Zhu, Shin-Tson Wu Jan 2004

Correlations Between Liquid Crystal Director Reorientation And Optical Response Time Of A Homeotropic Cell, Haiying Wang, Thomas X. Wu, Xinyu Zhu, Shin-Tson Wu

Faculty Bibliography 2000s

Correlations between the director reorientation time and its consequent optical response time (both decay and rise) of a homeotropic liquid crystal (LC) cell under crossed polarizers are derived theoretically based on small angle approximation. Results indicate that the optical response time is linearly proportional to the LC director reorientation time and is weakly dependent on the initial bias voltage. To validate the derived correlations, transient phase and transmittance responses at various bias voltages are analyzed numerically by solving the Erickson-Leslie equation. Pretilt angle is found to make an important contribution to the optical response time. Gray scale switching of the …

High-Yield Expression Of A Viral Peptide Animal Vaccine In Transgenic Tobacco Chloroplasts, Andrea Molina, Sandra Hervás-Stubbs, Henry Daniell, Angel M. Mingo-Castel, Jon Veramendi Jan 2004

High-Yield Expression Of A Viral Peptide Animal Vaccine In Transgenic Tobacco Chloroplasts, Andrea Molina, Sandra Hervás-Stubbs, Henry Daniell, Angel M. Mingo-Castel, Jon Veramendi

Faculty Bibliography 2000s

The 2L21 peptide, which confers protection to dogs against challenge with virulent canine parvovirus (CPV), was expressed in tobacco chloroplasts as a C-terminal translational fusion with the cholera toxin B subunit (CTB) or the green fluorescent protein (GFP). Expression of recombinant proteins was dependent on plant age. A very high-yield production was achieved in mature plants at the time of full flowering (310 mg CTB-2L21 protein per plant). Both young and senescent plants accumulated lower amounts of recombinant proteins than mature plants. This shows the importance of the time of harvest when scaling up the process. The maximum level of …

Time-Resolved Mueller Matrix Imaging Polarimetry, Ihor Berezhnyy, Aristide Dogariu Jan 2004

Time-Resolved Mueller Matrix Imaging Polarimetry, Ihor Berezhnyy, Aristide Dogariu

Faculty Bibliography 2000s

We present a new method of time-resolved Mueller matrix imaging polarimetry for spatial and temporal characterization of the polarization effects in backscattering from turbid media. The technique allows measuring the time evolution of spatially varying polarization patterns of diffusely backscattered light with picosecond resolution. A series of time-resolved polarization patterns are obtained at various time delays, are analyzed in sequence, and used to separate the polarimetric contributions of different scattering paths. Specific features of the 2D Mueller matrix components corresponding to light backscattered from colloidal suspensions were determined and characterized. The temporally- and spatially-resolved measurements permit detailed analysis of the …

Induction Of A Novel Class Of Diacylglycerol Acyltransferases And Triacylglycerol Accumulation In Mycobacterium Tuberculosis As It Goes Into A Dormancy-Like State In Culture, Jaiyanth Daniel, Chirajyoti Deb, Vinod S. Dubey, Tatiana D. Sirakova, Bassam Abomoelak, Hector R. Morbidoni, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

Mycobacterium tuberculosis enters the host by inhalation of an infectious aerosol and replicates in the alveolar macrophages until the host's immune defense causes bacteriostasis, which leads the pathogen to go into nonreplicative drug-resistant dormancy. The dormant pathogen can survive for decades till the host's immune system is weakened and active tuberculosis develops. Even though fatty acids are thought to be the major energy source required for the persistence phase, the source of fatty acids used is not known. We postulate that the pathogen uses triacylglycerol (TG) as a storage form of fatty acids. Little is known about the biosynthesis of …

Method For Determination Of Singlet Oxygen Quantum Yields For New Fluorene-Based Photosensitizers In Aqueous Media For The Advancement Of Photodynamic Therapy, Wade William Grabow Jan 2004

Method For Determination Of Singlet Oxygen Quantum Yields For New Fluorene-Based Photosensitizers In Aqueous Media For The Advancement Of Photodynamic Therapy, Wade William Grabow

Electronic Theses and Dissertations

Photodynamic therapy (PDT) has been investigated over the past three decades and is currently an approved therapeutic modality for skin cancer, the treatment of superficial bladder, early lung and advanced esophageal cancers, and age-related macular degeneration in a number of countries. In PDT, the absorption of light by a chromophore generates cytotoxic species such as reactive singlet oxygen, leading to irreversible destruction of the treated tissue. The measurement of the singlet oxygen quantum yield is an important determinant used to evaluate the efficiency of new photodynamic therapy agents developed in the laboratory, to screen potential photosensitizers in aqueous media.The singlet …

Partitioning A Graph In Alliances And Its Application To Data Clustering, Khurram Hassan-Shafique Jan 2004

Partitioning A Graph In Alliances And Its Application To Data Clustering, Khurram Hassan-Shafique

Electronic Theses and Dissertations

Any reasonably large group of individuals, families, states, and parties exhibits the phenomenon of subgroup formations within the group such that the members of each group have a strong connection or bonding between each other. The reasons of the formation of these subgroups that we call alliances differ in different situations, such as, kinship and friendship (in the case of individuals), common economic interests (for both individuals and states), common political interests, and geographical proximity. This structure of alliances is not only prevalent in social networks, but it is also an important characteristic of similarity networks of natural and unnatural …

A Comparative Static Analysis For Invasive Species Management Under Risk Neutral Preferences, Pamela Safford Jan 2004

A Comparative Static Analysis For Invasive Species Management Under Risk Neutral Preferences, Pamela Safford

Electronic Theses and Dissertations

This thesis investigates the optimal ex-ante mix of self-protection and self-insurance technologies employed to reduce the risk of biological invaders in the presence of exogenous variables within the probability and damage functions. This is accomplished by using a theoretical endogenous risk model that extends previously developed frameworks. This thesis contributes to the previous work in two ways. (1) Employing a general framework with simultaneous decision making over self-protection and self-insurance, this thesis analyzes how each parameter including income, the costs of each activity, an exogenous factor that affects only the probability of an invasion, and a separate exogenous factor that …

New Antiepileptic Drugs. A Clinical Overview, Sameer A. Otoom, Azhar S. Daoud Jan 2004

New Antiepileptic Drugs. A Clinical Overview, Sameer A. Otoom, Azhar S. Daoud

Neurosciences

After a gap of approximately 20 years, a new generation of antiepileptic drugs (AEDs) has recently been developed. More than 8 drugs have been licensed in at least one country during the 1990s. While lamotrigine, gabapentin, vigabatrin and oxcarbazepine are widely used in some countries, felbamate, topiramate, tiagabine, levetiracetam, and zonisamide are still used on a narrow scale. A feeling of optimism occurs after the development of these drugs, although only a small number of epileptic patients become free of seizures after the addition of these new AEDs to their regimen. Generally, the safety profile of the new AEDs is …

Effect Of Zooid Spacing On Bryozoan Feeding Success: Is Competition Or Facilitation More Important?, Marney C. Pratt Jan 2004

Effect Of Zooid Spacing On Bryozoan Feeding Success: Is Competition Or Facilitation More Important?, Marney C. Pratt

Biological Sciences: Faculty Publications

Most Recent bryozoan species are encrusting sheets, and many of these colonies have densely packed feeding zooids. In this study, I tested whether tight packing of feeding zooids affects food capture. Colonies of a bryozoan with an encrusting sheet form (Membranipora membranacea) were dissected to produce individuals whose feeding zooids were (1) closely packed, (2) more widely spaced, or (3) isolated. For each type, rates of particle ingestion were measured in still water and in a freestream velocity of 2.7 cm s-1. Ingestion rate increased when zooids were closest together, probably because of reduced refiltration and increased feeding current strength …

Characterization Of Drawn And Undrawn Poly-L-Lactide Films By Differential Scanning Calorimetry, John F. Turner Ii, A. Riga, Anne O'Connor, Jing Zhang, Jennifer Collis

Chemistry Faculty Publications

Poly-L-lactic acid (PLLA) is an optically active, biocompatible and biodegradable polymer that has been widely investigated as an artificial cell scaffold material. In its most crystalline form, PLLA is highly anisotropic and is one of the most piezoelectric polymers known. Conversely, amorphous PLLA exhibits little, if any, piezoelectric behavior. Compression molded PLLA films can be endowed with varying amounts of crystalline character and piezoelectricity by uniaxially stretching the polymer in a hot air bath. Understanding the precise crystalline architecture of PLLA that results from tensile drawing is important for constructing cell scaffolds that have highly tailored biodegradation and cell guiding …
