Here at the HPMI, a novel photovoltaic device structure was created, called the wire-shaped dyesensitized solar cell (WS-DSSC). This cell has been primarily synthesized and fabricated in the laboratory environment with no control. To date, dye-sensitized solar cells (DSSCs or DSCs) have reached an efficiency of 11.9%, which is one of the fastest inclines towards higher efficiency cells. Therefore, a repeatable manufacturing process is needed to fully transfer the incredible gains of this...
Show moreHere at the HPMI, a novel photovoltaic device structure was created, called the wire-shaped dyesensitized solar cell (WS-DSSC). This cell has been primarily synthesized and fabricated in the laboratory environment with no control. To date, dye-sensitized solar cells (DSSCs or DSCs) have reached an efficiency of 11.9%, which is one of the fastest inclines towards higher efficiency cells. Therefore, a repeatable manufacturing process is needed to fully transfer the incredible gains of this structure. This will greatly influence the field of organic electronics, specifically organic solar cells. Due to the lack of volatile materials, the use of a solid-state electrolyte (SSE) could increase the safety of organic electronic devices. The specific scope of this research is the development of anoptimized SSE by introducing a polymer material to an aqueous electrolyte, creating a solid-state electrolyte. The printability aspect of this solid-state electrolyte is also studied to enable the use ofadditive manufacturing in the fabrication of WS-DSSCs. Upon analyzing the viscosity flow curves generated by the collected data they reveal that PVDF, specifically at the 8 wt/wt% concentration, has a much higher initial viscosity than the PEO solution of the same concentration. Leading to the conclusion that it will demonstrate a higher level of shape retention when compared to a PEO solution. Numerically, the initial viscosity of the PVDF sample was 2,780 [Pa*s] compared to just 4.82 [Pa*s] generated by the PEO sample. Conclusive data about the printing behaviors both PEO and PVDF electrolyte samples were not collected for the purposes of comparison. The use of a solid-state electrolyte in additive manufacturing techniques such as fused deposition modeling to print an SSE will greatly improve the speed at which organic electronics can be produced.

In a perfect world, every student would learn exactly the same way and the teacher wouldn't have to change his or her teaching method. However, each student in a classroom learns differently depending on his or her temperament. The genetically acquired temperament of a student has a variety of differences that may affect learning styles, in turn impacting academic performance and thus, grade point average.

Show moreIn a perfect world, every student would learn exactly the same way and the teacher wouldn't have to change his or her teaching method. However, each student in a classroom learns differently depending on his or her temperament. The genetically acquired temperament of a student has a variety of differences that may affect learning styles, in turn impacting academic performance and thus, grade point average. This in turn affects the student's overall confidence in school as well as the teacher's outlook on their class. Teachers may have a hard time adjusting to new students every year regarding both class environments as well as teaching styles. To address these problems, this complementarity mixed method study explores data of student temperament, learning styles, and GPA.

Show moreThis thesis provides an overview of the history, development and of controversies in DNA testing in relation to precedence based on case law, as well as the future of evolving DNA technology in the Criminal Justice System. While there are setbacks of the way DNA is used today, the positive expansion of DNA technology has also been recognized. The immense possibilities of DNA are still being discovered, and lie in defeating limitations of evidence collection and lab quality. The knowledge and implementation of expanding DNA technology will aid in the creation and solid foundation of a more equipped justice system in the fight against crime while protecting the innocent. The goals of the Criminal Justice System in promoting and protecting the privacy, civil liberties and public safety of its citizens can only be achieved through the proper and full use of DNA technology. With a more structured and supported system of evidence gathering, coupled with better lab procedures and analysis, the development and growth of DNA's usage will be seen in rightful convictions and aid in the review of past injustices. The ability to use DNA technology to its full potential will be an important and influential tool for the future in the judicial process.

Paternal behavior is an interesting and important research topic due to its integral contribution to the fitness and well-being of multiple species, including humans. Although paternal behavior is well described in literature, attempts at neurobiological characterization have yielded conflicting results that fail to address brain region interconnectivity. This study was designed to evaluate the relationship between afferent VMH circuitry and the onset of paternal behavior, using the prairie...
Show morePaternal behavior is an interesting and important research topic due to its integral contribution to the fitness and well-being of multiple species, including humans. Although paternal behavior is well described in literature, attempts at neurobiological characterization have yielded conflicting results that fail to address brain region interconnectivity. This study was designed to evaluate the relationship between afferent VMH circuitry and the onset of paternal behavior, using the prairie vole (Microtus ochrogaster) model. Sexually naïve male prairie voles received injections of the retrograde neurotracer Fluoro-Gold (FG), into the VMH. Two weeks later, subjects were exposed to either conspecific pups, contained within a tea-ball, or an empty tea-ball (control) for 1 hr. Immunohistochemical labeling was conducted for both FG and the neuronal activity marker Egr-1, in order to evaluate neuronal and afferent pathway activation between the ventromedial hypothalamus (VMH) and the amygdala (AMYG), bed nucleus of the stria terminalis (BNST), lateral septum (LS) and ventral tegmental area (VTA). Similar to the pathway implicated in the onset of maternal behavior, the results of this study showed pup exposure-induced neuronal activation in the AMYG and BNST, particularly in the efferent pathways from these two brain areas to the VMH. This effect was not found in the LS and VTA projection neurons to the VMH. Together, the data suggests a brain region-specific neuronal activation by pup exposure in particular brain circuitry, implicating its possible involvement in paternal behavior.

Show moreThe term Afrocolombianidad embodies the kaleidoscope of cultural spaces and cultural productions of the African descendant population in Colombia. This investigation is intended to generate and contribute to greater academic and popular interest in the myriad of cultural expressions of Afro-Colombians which will serve to enrich the overall spectrum of Hispanic culture in the Americas. The argument of this thesis is two-fold: Afro-Colombian cultural productions are unique representations and reflections of Afro-Colombian history and social issues; and the cultural identity of Afro-Colombians is unique and merits further study in the context of Hispanic cultural studies in Spanish. Three specific genres of Afro-Colombian cultural production will be investigated in order to bring the argument to fruition, each receiving a chapter of discussion with the following titles: "Linguistic Identities of the Caribbean," "Literary Expressions of Afro-Colombia," and "Stilo y Sabor: Afro-Colombian Music and Dance." Specific cultural productions covered in the thesis include: Palenquero, San Andres Creole, the works of Candelario Obeso, Jorge Artel, and Gabriel Garcâia Mâarquez, Champeta, Cumbia, and Salsa (specifically in Cali). While the information presented in this thesis may not be considered as completely exhaustive as to the many aspects of each cultural expression to be studied, each item of cultural production is given ample attention in order to completely and sufficiently bring the initial two-fold argument of the investigation to fruition.

Show moreThe gafftopsail catfish, Bagre marinus, is a particularly abundant species of marine, mouthbrooding catfish found throughout the Gulf of Mexico. In this study, the age, growth, and maturity of this species was determined for a population within Apalachicola Bay, a large highly productive estuary in Northwest Florida designated as a National Estuarine Research Reserve. New age, growth, and maturity data presented for B. marinus is relevant as the continued exploitation of highly sought-after species in the Gulf of Mexico is likely to lead to the development of a fishery targeting B. marinus similar to the marine catfish fisheries of Central and South America. A total of 235 specimens were sampled in this study between April 2018 to August 2019. Age determination through use of counting the growth bands of lapillal otoliths yielded an age range of 1 to 25 years old for females and 1 to 14 years old for males. Growth was modeled with five different length-at-age models with sexes being modeled independently. Akaike information criterion corrected for a small sample size (AICc) was used to directly compare models and determine most appropriate model for the data presented. For females in this study it was found that the two three-parameter von Bertanlanffy growth models (k = 0.171 0.015, L∞ = 515.03 7.50 mm (fork length, FL)) yielded the best fits for the length at age data of the females with strong support also for the Gompertz model (k = 0.217 0.016, L∞ = 507.84 6.37 mm (FL)). For males in this study, all models excluding the two-parameter von Bertanlanffy growth model exhibited comparable fits of the data with the logistic model yielding the best fit for males (k = 0.429 0.056, L∞ = 470.31 11.55 mm (FL)). Maturity ogives calculated within this study suggest that age-at-maturity was 3 years old for females and 2 years old for males. Age and growth results in this study differed from those estimated for other populations of B. marinus in the Gulf of Mexico.

Catecholaminergic polymorphic ventricular tachycardia (CPVT), also called exercise-induced ventricular tachycardia is a hereditary disease that can cause sudden cardiac death in human patients. Interestingly, while patients with CPVT have normal function of the heart at rest, they show life-threatening arrhythmias during physical activity or acute emotional stress.

Show moreCatecholaminergic polymorphic ventricular tachycardia (CPVT), also called exercise-induced ventricular tachycardia is a hereditary disease that can cause sudden cardiac death in human patients. Interestingly, while patients with CPVT have normal function of the heart at rest, they show life-threatening arrhythmias during physical activity or acute emotional stress. Autonomic nervous system is known to have a role in arrhythmia pathogenesis, and its response changes with aging. However, little is known that how autonomic regulation with aging contributes to arrhythmia burdens in CPVT. Methods: To test our hypothesis, we examined ECG recording with a catecholaminergic challenge (isoproterenol, 3mg/kg + caffeine, 120mg/kg) in anesthetized CPVT mice at different age groups (6 weeks old, 12 weeks old, and 48 weeks old). Results: In CPVT mice, the frequency of arrhythmias were increased with aging. The resting heart rate (HR) decreased with aging, whereas the HR response after adrenergic stress was significantly increased. The average RR interval also increased in advanced age, suggesting a possibility of an increased autonomic regulation. Conclusion: We found that arrhythmia incidence worsens by lowering intrinsic HR, and possibly by a modulation of parasympathetic nerve activity in CPVT mice with advanced age.

Show moreThe present investigation examined the effects of aging and cognitive workload on speech production using temporal and frequency measures of acoustics. The following hypotheses were made: older speakers will have longer phoneme durations than will younger speakers; older speakers will have shorter F2-transitions and smaller F2-transition frequency extents than will younger speakers; all speakers will exhibit greater proportional changes to these measures under increased cognitive workload conditions. Eight adults, four younger and four older, equally matched for sex, participated. They completed a sentence-level Stroop task in two cognitive workload conditions: low cognitive load (congruent Stroop condition) and high cognitive load (incongruent Stroop condition). Participants produced the sentence sixteen times, eight productions for both conditions. Plosive-vowel syllables that came before the Stroop-segment, at the Stroop-segment, and after the Stroop-segment of the sentence were selected for measurement from each sentence production. All speakers exhibited longer phoneme durations before and at the Stroop-segment in comparison to afterwards. Speakers also exhibited longer and more extensive vowel transitions before and at the Stroop-segment in comparison to the post-Stroop segment. In the incongruent condition, the Stroop-segment had longer F2-transition durations. The older adults had longer F2-transitions than the younger adults. The F2-transition frequency extent was greatest at the Stroop-segment. The older adults had wider F2-transitions at the Stroop-segment that further widened during incongruent conditions. These results suggest that the effects of speaker anticipation of the cognitive task were manifested by speech adaptations that occurred as a function of the word’s position in the sentence.
