Desiccation Tolerance In Insect Cells, John Marcus Anderson

Masters Theses

In anhydrobiotic animals a reoccurring strategy to survive water stress involves the accumulation of low molecular weight solutes (e.g., trehalose) and highly hydrophilic macromolecules [e.g., late embryogenesis abundant (LEA) proteins]. We utilized two different water-stress models (spin-drying, and hyperosmotic dehydration) to investigate the impact of transgenic expression of a trehalose transporter [BT003466 (TRET)] and of a group 1 LEA protein [ACX81198 variant (LEA1)] on membrane integrity in cell lines from Spodoptera frugiperda (Sf-21) and Drosophila melanogaster (Kc167), respectively. Kc167 cells were challenged with sucrose or trehalose concentrations ranging from 0 to 200 mM supplemented in standard culture medium. Significant inhibition …

Feeding Behavior Of Nestling Eastern Bluebirds (Sialia Sialis) In East-Central Illinois, Amanda Lamb

Masters Theses

I observed feeding of nestlings in Eastern Bluebirds in nest boxes in east-central Illinois. Provisioning rate of males and females were compared and early observation periods (younger nestlings) were compared with late observation periods (older nestlings). I also compared the average food size brought to the nestlings by males and females and during early and late observations. No significant differences were found between average food sizes throughout the study. In addition, food size was not significantly correlated with mean nestling weights within a brood. However, males had significantly fewer confirmed feedings than females for the last observation period. In addition, …

The Toxicity Of Acetaminophen, Caffeine And Carbendazim In Earthworms (Eisenia Fetida), Matthew M. Bulman

Masters Theses

There has been a need for the assessment of ground water contamination risk on terrestrial organisms. One terrestrial organism, Eisenia fetida, was chosen as a test species and exposed to three common pharmaceutical and/or pesticide related contaminants: acetaminophen (CAS#103-90-2), caffeine (CAS#58-08-2) and carbendazim (CAS#10605-21-7), respectively. Levels of contamination varied from grams per liter to micrograms per liter (ppb) using distilled water as the solvent. Eisenia fetida was examined through a 28 day range/index toxicity test.

Linking The Colonization Rate Of Vesicular Arbuscular Mycorrhizae (Vam) To Species Dynamics In Succession, Jie Luo

Masters Theses

Vesicular arbuscular mycorrhizae (YAM) are the most common mycorrhizal fungi that form symbiotic associations with plant species. They form hyphae, vesicles and arbuscules which expand root surface area and exchange nutrients within root cells. Greater abundance of YAM can result in more nutrient uptake and disease resistance to the host plant. While mycorrhizae are often important to the growth and reproduction of individual species, their role in regulating plant community dynamics is less clear. Previous research has shown that YAM are tightly related to plant traits such as relative growth rate, foliar N and P concentrations, and responses to soil …

Dibenzimidazolium Salts And Their Interactions With 1,5-Dinaphtho-38-Crown-10, David B. Bernthal

Masters Theses

The use of imidazolium salts in mechanically interlocked molecules, like pseudorotaxanes, is of interest because they can be functionalized with side arms that allow for coordination chemistry. It has been previously shown that tetraakylbenzobisimidazolium salts successfully thread through crown ethers, such as 15DN38C10 or BPP34C10, to form pseudorotaxanes. As an extension of the results that were gathered about this novel template, it was our goal to explore the degree to which larger imidazolium salts interact with such crown ethers. This research focused on the interactions between 15DN38C10 and dibenzimidazolium cations that were tetra-substituted with methyl groups, butyl groups, and benzyl …

Internal Motion In Weakly Bound Halomethane Complexes, Amelia J. Thomas

Masters Theses

A complementary blend of computational and spectroscopic methods has been used to analyze three halomethane complexes which exhibit different types of internal motion. In CH2FrCO2, the CH2F2 undergoes a "rocking" motion which inverts the dipole moment component along the c axis. For thjs complex, the spectra of six isotopologues were measured and an experimental structure was determined (see figure). The barrier to inversion was 142(3) cm·1 based on an experimental AE (AE is the energy difference between v=0+ and v=ff), which is in good agreement with the ab imtio ZPE-corrected barrier of 122 cm •1 . Upon comparison with similar …

Dynamic Crisis Modifiers: Bp's Gulf Of Mexico Oil Spill, Catherine G. Bocke

Masters Theses

When an organizational crisis emerges, crisis communicators must craft specific messages for their stakeholders and the public. While an organization is attempting to shape how the public perceives it during a crisis, the media work to frame the public's perception of the crisis through news coverage. Situational crisis communication theory (SCCT) is a prescriptive theory that assesses a crisis situation to determine which crisis response will best protect the organization's reputation. Two factors, crisis history and severity, serve as modifiers that can affect the crisis situation, and ultimately influence the best response. BP's Gulf of Mexico oil spill serves as …

Masters Theses

Oxycyte is a perfluorocarbon-based material that can mimic the oxygen carrying capabilities of hemoglobin and is in the testing stages of acting for use as a blood substitute. However, a problem associated with using Oxycyte as a blood substitute is that it clumps together too easily and does not coagulate. An approach for studying the problem uses optical tweezers to help model the forces between Oxycyte particles. Elements of optical tweezers, including laser beams, microscopes, and operation by trapping particles with light will be outlined. An experimental system created to study the forces between particles is presented. Experimental issues and …

The Relationship Between Dialectical Self And Hedonic, Eudaimonic, And Social Well-Being, Ayaka Hisanaga

Masters Theses

The present study examined the relationship between a dialectical self and three different conceptions of well-being: hedonic, eudaimonic, and social well-being. Dialectical self refers to the ability to recognize contradictions and changes in the self. The study was built upon previous research by Spencer-Rodgers and her colleagues (2004) that found a negative relationship between being dialectical and hedonic well-being (specifically selfesteem and life satisfaction). Although this previous study indicated that the more one perceives oneself as tolerant of contradiction and change, the more one would tend to experience life dissatisfaction and negative feelings (i.e., hedonic well-being), the current study predicted …

Effect Of Reservoir Discharge And Sanitary Effluent On An Urban Stream, Daniel Hiatt

Masters Theses

Eutrophication of aquatic ecosystems may occur from several sources, primarily from anthropogenic inputs. Excess nutrient deposition can result in eutrophication and community compositional shifts in organisms located in impacted ecosystems. In the Sangamon River located outside Decatur, IL, discharge from the local reservoir, which receives inputs from both a city landscape and agricultural landscape and a wastewater treatment plant (WWTP). These may result in a large influx of nutrients into this system. Increased nutrient levels have the potential to shift benthic periphyton, and macroinvertebrate communities and cause extinction of low tolerance native species. To examine the impacts of inputs for …

Inferencing Abilities Of Children With Specific Language Impairment, Kelsey J. Depew

Masters Theses

Inferencing is the ability to make judgments based upon limited information. It is necessary for basic problem solving, negation social interaction, and comprehension of oral and written language. Despite the importance of inferencing in daily life, there are currently no commercially available tests dedicated entirely to the assessment of inferencing. Previous research has demonstrated a developmental progression of inferencing abilities in neurotypical children. However, no clinical norms exist. Additionally, little research has been conducted regarding the inferencing abilities of children with language impairments. The purpose of this project was to compare inferencing abilities of children with language impairment to typically …

Viewing political violence within the context of one of the most divisive political regions in the nation-central Illinois, this thesis utilizes an unprecedented comprehensive reading of the region's provost marshal reports as its window into community life in postEnrollment Act central Illinois. From this newfound perspective this thesis uses those reports to create a framework to reinterpret traditional sources such as newspapers and government officials' correspondence. It finds that the upsurge in violence in postEnrollment Act central …

Identification Of Starry Milia-Like Cysts In Seborrheic Keratoses And Malignant Melanomas Using Image Processing Techniques, Viswanaath Subramanian

Masters Theses

"Seborrheic keratoses are the most common benign tumors found in older individuals. Seborrheic keratoses are normally benign in nature, but sometimes in a large lesion area of seborrheic keratoses, secondary tumors, or squamous cell carcinoma in situ or malignant melanoma may occur. It has been found that seborrheic keratoses have a few features that distinguish them from melanomas. Milia-like cysts, comedo-like openings and network-like structures are the most prominent features found in seborrheic keratoses. Comedo-like openings are pigmented structures and are mostly oval yellowish, brown or black in appearance. They can also be observed in melanocytic lesions and melanomas. Milia-like …

Automatic Detection Of Annular-Granular Patterns In Melanoma In Situ Dermoscopy Images, Parivash Hajiyani

Masters Theses

"Early detection of malignant melanoma greatly benefits patients, as the overall success is dependent on finding these melanomas before they reach the invasive stage. Dermoscopy is a non-invasive skin imaging technique that studies have shown can improve the diagnostic accuracy of dermatologists by as much as 30% over clinical examination. In this project machine vision and image analysis techniques are used to detect annular granular areas in dermoscopy images automatically. The proposed algorithm utilizes the luminance ratio between annular and granular areas within the darkest 30% of the lesion. All points whose luminance value are less than 30% of the …

Blast And Impact Resistance Of "Long" Carbon Fiber Reinforced Concrete, Darwin Ishmael Keener

Masters Theses

"Traditional reinforced concrete is one of the most commonly used materials for protective structures. However, conventional reinforced concrete (RC) is susceptible to significant spalling (small to medium sized chunks of concrete detaching from the original member) during blast events. The force of the blast turns spalled concrete into projectiles, resulting in secondary fragmentation. Furthermore, the concrete debris makes for difficult and uncertain footing. Both phenomena endanger personnel and complicate post-blast recovery efforts. Changes need to be made to conventional reinforced concrete structures to improve their blast and impact survivability and fragmentation resistance in order to protect personnel and facilitate post-blast …

Microstructure And Mechanical Properties Of Silicon Carbide-Titanium Diboride Ceramic Composites, Derek Scott King

Masters Theses

"The microstructure, hardness, fracture toughness, Young's modulus, strength and Weibull modulus of silicon carbide-titanium diboride (SiC-TiB₂) ceramics were studied. First, SiC-TiB₂ ceramics with 15 vol.% TiB₂ particles were processed using two green processing methods, spray drying (ST) and ball milling (SiC-15TiB₂). In addition, SiC-TiB2 ceramics with TiB₂ contents ranging from 0 to 100 vol.% were produced to determine a TiB₂ content that produced the best combination of mechanical properties. From spray drying, segregation of the TiB₂ particles in ST led to a granule-like microstructure and spontaneous microcracking in the final ceramic. In ceramics containing 20 and 40 vol.% TiB₂, the …
