Uncovering the Hidden Excited State toward Fluorescence of an Intracellular pH Indicator

Creator:: Tang, Longteng, Zhu, Liangdong, Wang, Yanli, and Fang, Chong
Abstract:: Intracellular pH (pH(i)) imaging is of paramount importance for life sciences. In this work, we implement the ultrafast electronic and stimulated Raman spectroscopies to unravel the fluorescence mechanism of an excitation-ratiometric pH(i) indicator in basic aqueous solution. After photoexcitation of the pH(i) indicator HPTS, a hidden charge-transfer (CT) state following...

Experimental thermodynamic first and second law analysis of a variable output 1-4.5 kWe, ICE-driven, natural-gas fueled micro-CHP generator

Creator:: Taie, Zachary and Hagen, Christopher
Abstract:: This work experimentally assesses the thermodynamic performance of the only single kWe, variable-output continuous duty, internal combustion engine driven, residential micro-combined heat and power (mCHP generator (Marathon Engine Systems ecopower) available in the United States. The system underwent steady state testing over its full operating range, and first (energy) and...

Dendrometry Field Manual

Creator:: Strimbu, Bogdan M.
Abstract:: As it was conceptualized, the manual is aligned with other field manual that are currently in use by different universities, such as Mississippi State University, Stephen F Austin, or University of British Columbia. The present manual is the first unified version of Louisiana Tech University of a Field Manual to...

Pummerer Cyclization Revisited: Unraveling of Acyl Oxonium Ion and Vinyl Sulfide Pathways

Creator:: Li, Xin and Carter, Rich G.
Abstract:: Two viable pathways (vinyl sulfide and acyl oxonium ion) for the Pummerer cyclization have been unraveled that expand the reaction scope and capabilities. Use of Bronsted-enhanced Lewis acidity was key to realization of the vinyl sulfide pathway, whereas selective complexation of the sulfur lone pair facilitated the unprecedented acyl oxonium...

Secondary Metabolism and Interspecific Competition Affect Accumulation of Spontaneous Mutants in the GacS-GacA Regulatory System in Pseudomonas protegens

Creator:: Yan, Qing, Lopes, Lucas D., Shaffer, Brenda T., Kidarsa, Teresa A., Vining, Oliver, Philmus, Benjamin, Song, Chunxu, Stockwell, Virginia O., Raaijmakers, Jos M., McPhail, Kerry L., Andreote, Fernando D., Chang, Jeff H., and Loper, Joyce E.
Abstract:: Secondary metabolites are synthesized by many microorganisms and provide a fitness benefit in the presence of competitors and predators. Secondary metabolism also can be costly, as it shunts energy and intermediates from primary metabolism. In Pseudomonas spp., secondary metabolism is controlled by the GacS-GacA global regulatory system. Intriguingly, spontaneous mutations...

Instability of the Northeast Greenland Ice Stream over the last 45,000 years

Creator:: Larsen, Nicolaj K., Levy, Laura B., Carlson, Anders E., Buizert, Christo, Olsen, Jesper, Strunk, Astrid, Bjork, Anders A., and Skov, Daniel S.
Abstract:: The sensitivity of the Northeast Greenland Ice Stream (NEGIS) to prolonged warm periods is largely unknown and geological records documenting such long-term changes are needed to place current observations in perspective. Here we use cosmogenic surface exposure and radiocarbon ages to determine the magnitude of NEGIS margin fluctuations over the...

Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Expression of a Structural Protein of the Mycovirus FgV-ch9 Negatively Affects the Transcript Level of a Novel Symptom Alleviation Factor and Causes Virus Infection-Like Symptoms in Fusarium graminearum

Creator:: Bormann, Joerg, Heinze, Cornelia, Blum, Christine, Mentges, Michael, Brockmann, Anke, Alder, Arne, Landt, Svenja Kim, Josephson, Brian, Indenbirken, Daniela, Spohn, Michael, Plitzko, Birte, Loesgen, Sandra, Freitag, Michael, and Schaefer, Wilhelm
Abstract:: Infections of fungi by mycoviruses are often symptomless but sometimes also fatal, as they perturb sporulation, growth, and, if applicable, virulence of the fungal host. Hypovirulence-inducing mycoviruses, therefore, represent a powerful means to defeat fungal epidemics on crop plants. Infection with Fusarium graminearum virus China 9 (FgV-ch9), a double-stranded RNA...

Visual Metaphors on Album Covers: An Analysis into Graphic Design's Effectiveness at Conveying Music Genres

Creator:: Le, Vivian T.
Abstract:: The rise of digital streaming has largely impacted the way the average listener consumes music. Consequentially, while the role of album art has evolved to meet the changes in music technology, it is hard to measure the effect of digital streaming on modern album art. This research seeks to determine...
