Applications of Supercapacitors in Robotic Systems
Get PDFThis project explores the utilization of a bespoke supercapacitor system to energize and propel a robot across various challenging courses. The custom supercapacitor setup serves as the primary power source, providing rapid charging capabilities and high energy density. The research investigates the integration of this innovative power solution into the robot\u27s design, aiming to optimize its performance and endurance in competitive environments
Length-Weight Relationship of Flier (Centrarchus macropterus) in Moro Creek
Get PDFLength-weight relationships provide foundational knowledge for managing fisheries populations. However, there are many species where the length-weight relationships are not widely understood. The Flier (Centrarchus macropterus) is one species where there is a lack of information regarding its length-weight relationship and spatial variation associated with this relationship. A new study was needed to assess the length-weight relationship for this species. Fliers were collected from upper Moro Creek during October 2023. Multiple gears (backpack electrofishing and seining) were employed to increase detection of this species. Length (mm), and weight (g) were recorded for every individual observed. A total of 85 Flier were sampled from four sites in the upper Moro Creek watershed, and their average (±SE) length was 75.7 (±1.8) mm and average weight was 8.5 (±0.7). The length-weight for Flier in upper Moro Creek was Log(W) =-4.2 + 2.7Log(L). Mean (±SE) Fulton’s condition factor (K) was 1.7 (±0.1), mean LeCren’s relative condition factor (Kn) was 1.0 (±0.1) and mean relative weight (Wr) was 100.5 (2.9). Our estimates of condition on this species are similar to other estimates of condition for this species in other water bodies. However, it is apparent that our data displays some sampling bias to older (larger) individuals in this population, which may have influenced our ability to accurately estimate the length-weight relationship of this species. This research provides a foundation of knowledge on the length-weight relationship of Fliers in predominantly lotic ecosystem in Arkansas
Faculty Perceptions in Working with Students with Disabilities Who Have Accomodations
Get PDFThis research investigated the university faculty members’ attitudes towards accommodations for students with disabilities. A survey was emailed to 243 faculty members at a medium-sized public four-year University in Central Arkansas and resulted in 59 responses. The survey contained 26 prompts with 9 being demographic based questions. Other than the demographic questions, the other 17 prompts were created using an alternating Likert scale with opposing values assigned to 1 and 7. These prompts followed themes regarding knowledge of the disabilities services, institutional support and personal teaching policies. Findings found that majority of faculty had a positive attitude when it regarded policies that provided students with accommodations as well as understanding of the services. However, findings also indicated a strong need for additional training when it came to these policies. Statically significant differences in perceptions were found among faculty of differing prior training levels and gender. Implications and further findings are discussed
Evaluating the Importance of Biosecurity in Swine Operations
Get PDFSwine health is critical to maintaining a profitable and productive swine operation. Biosecurity and sanitation are important practices that help maintain herd health. This study aimed to discover how biosecurity protocols and management practices differ between swine operations of different sizes. With diseases such as Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Brucellosis, and Porcine Circovirus type 2 (PCV2) being common in the swine industry, a strong biosecurity protocol protects swine farmers from financial losses associated with disease outbreaks. In 2004 alone, the estimated financial loss to PRRSV was over $761 million. Data concerning biosecurity and sanitation was collected from three swine farms in Arkansas via interviews. The farms were selected for this study based on their sow population, location in Arkansas, and their willingness to disclose information about their management practices. A comparative analysis was used to understand how each operation implemented biosecurity and sanitation practices and what key differences could be found. The collected data revealed that no differences (p \u3e 0.05) in disease outbreaks existed among the farms surveyed although they have different biosecurity features. A key biosecurity feature that contributed to this result was that all three farms were isolated from other swine operations and did not allow farm laborers to work with swine outside of the operation. Varying levels of biosecurity enforcement existed among the three operations, but it is evident that a biosecurity protocol not only protects the swine within the operation but also the health and finances of farm owners and their staff
Spatial Assessment of Slender Madtom (Noturus exilis) Diets within the Illinois Bayou
No full textThe Slender Madtom (Noturus exilis) is a common species with a widespread distribution across the Mississippi River basin. In Arkansas, they can be found in upland rivers/streams in the Arkansas River and White River watershed. Very little data has been collected on the diet of this species and how it varies. We wanted to spatially assess the diet of Slender Madtoms. Slender Madtoms were sampled from 8 sites in the Illinois Bayou watershed using seines and kick nets. Small-scale gastric lavage was used to extract diet data from all individuals. All prey items were preserved and identified to the genus level (if possible). Bray-Curtis dissimilarity was used to assess the composition of prey items between sites. A total of 157 different prey items from 41 fish (43-88 mm), covering 6 orders were extracted from Slender Madtoms during September-October (2023). Prey items consisted mostly of Chironomids (True Flies, n= 74), Heptageniid (Mayflies, n= 27), and Philopotamid (Caddisflies, n=18). There were varying levels of diversity among Slender Madtom diets from site to site; Shannon-Weiner Species Diversity Index (H=0.10-1.97), Evenness (E=0.65-1.00), and Simpson’s Dominance Index (1-D= 0.00-0.80). Slender Madtom diets from the lowest sampling site were more similar to diets from other sites (mean [±SE] Bray-Curtis Distance=0.51 [±0.13]), than the upper most site (mean Bray-Curtis Distance= 0.93 [±0.17]). The most diverse diets observed in this species were from the lowest site on Illinois Bayou (n= 38 prey items, 5 orders), suggesting a spatial relationship in diet diversity. Further sampling will incorporate diets from Slender Madtoms at more sites, and also assess temporal changes in diets from fish at these sites. This research will aid in the understanding of Slender Madtom diets and how they vary spatially
Ranking Arkansas: Student-Surveyed Mental Maps and Preference Mapping of Arkansas Counties, 2018-2021
No full textArkansas has been described as “two states in one”, with two diagonally split regions: a growing upland north and west, and a declining lowland south and east. However, do Arkansas residents share these in-state regional associations of “growth” and “decline”? 48 Arkansas high school graduates enrolled in the “Arkansas Geography” course at Arkansas Tech University between 2018 and 2021 were surveyed about their preferences of all 75 Arkansas counties. Only 10 of 75 Arkansas counties were rated positively by students, with higher scores occurring around Northwest Arkansas, Russellville, and Hot Springs. The lowest-rated counties were in the Arkansas Delta and in very rural areas of the Ozarks or Ouachita mountains. A possible “home effect” exists as students rated their home counties highly, but the effect was largely minimized. County ratings were consistent across the 2018, 2020, and 2021 surveys. Most Arkansas regions were rated higher than the constituent counties in each region, giving credence to regional perceptions as ideas. These results are useful, not only for understanding intrastate issues within Arkansas, but also because associating high preferences with population and economic growth can aid future decision-making from planners and other stakeholders
