Finding Geometric Variances From Nominal Measurements, Austin Bridenthal Apr 2025

Finding Geometric Variances From Nominal Measurements, Austin Bridenthal

American Journal of Rising Scholar Activities

This study worked to find differences between the measurements of what parts should be and what they actually were. When a part is manufactured, it is given a nominal measurement which provides the exact geometric numbers representing that section of the part. The true measurements of parts are almost never exactly the same as the nominal measurement, due to varying production issues during component manufacture. A Hexagon Laser Scanner (LS) was used to create computer generated figures of the parts, while Siemens NX, CATIA V5, Creo, Solidworks, and Inventor softwares were used to create Computer-Aided Design (CAD) models of the …


Modification Of Process Inputs Using Hog Cooling Pads, Gilbert Benitez Apr 2025

Modification Of Process Inputs Using Hog Cooling Pads, Gilbert Benitez

American Journal of Rising Scholar Activities

Purdue University researchers have developed a low-cost hog cooling pad which uses ground-based water as a coolant for sows in farrowing crates. Initial testing has proven the positive effects of the unit on sow and piglet productivity, but thus far little research has been done on seeing whether or not the use of the pads reduces water consumption by the animals or how much energy is required to operate the units. This study examined data collected during an indirect calorimetry testing program. The limited availability of water sensors hindered the meaningfulness of the water consumption data, but the energy consumption …

Probing Surface Characteristics Of Plant-Based Protein Powders, Anthony Scott

American Journal of Rising Scholar Activities

Plant-based protein powders are expected to take-on a larger role in human diet as concerns regarding animal-based protein production grow. Unfortunately, not much physical property information about these proteins is available. This study was an attempt by researchers to perform an initial investigation of five powders: Mung bean, peas, pumpkin seed, Fava bean, and Soybeans. Typical particle sizing was determined, along with the surface morphology. Shear testing on the bulk materials was performed to establish the powders’ potential flowability. Inverse gas chromatography provided surface energies of the five protein types, and an X-ray photoelectron spectrograph was used to determine the …


Shock Pulse Absorption Using An Elastomeric Structure Enhanced With Non-Newtonian Fluid, Noah Herbert Apr 2025

Shock Pulse Absorption Using An Elastomeric Structure Enhanced With Non-Newtonian Fluid, Noah Herbert

American Journal of Rising Scholar Activities

Non-Newtonian fluids have unique properties which may make them ideal materials to be used in the manufacture of safety equipment. Different types of materials have widely differing properties, and researchers are only now beginning to investigate the physical properties of these various materials. Two different forms of impact experimentation were selected for the ongoing investigation, hammer blow testing and air cart collision testing. Specialty pucks were manufactured, along with control specimens for physical property determination. Normalized energy absorption in collision was recorded against the frequency of the response for 19 different materials. In general, the non-Newtonian fluid filled pucks exhibited …


Changes In The Δ17o Values Of Nitrate Contained In Sedimentary Strata Of The Confidence Hills Formation To Mark Shifts In Precipitation Over Time During The Pliocene-Pleistocene Transition, Brandon Botha Apr 2025

Changes In The Δ17o Values Of Nitrate Contained In Sedimentary Strata Of The Confidence Hills Formation To Mark Shifts In Precipitation Over Time During The Pliocene-Pleistocene Transition, Brandon Botha

American Journal of Rising Scholar Activities

During the Pliocene-Pleistocene transition, the Earth went through significant changes. The Earth transitioned from a warm, relatively wet climate to a cooler and drier climate with the formation of ice caps. The goal of this project was to create a tool to be able to evaluate the ability of a paleo-climate model to predict changes in mean annual precipitation or determine what caused these changes. The main hypothesis was changes in the Δ17O values of nitrate contained in the sediments of the Confidence Hills formation would mark shifts in precipitation during the Pliocene-Pleistocene transition. The collected samples were crushed using …


Chemical Enhancement Of Mechanically Fibrillated Nanocellulose (Mcnf) Films For Improved Mechanical Performance, Robert Miller Apr 2025

Chemical Enhancement Of Mechanically Fibrillated Nanocellulose (Mcnf) Films For Improved Mechanical Performance, Robert Miller

American Journal of Rising Scholar Activities

Mechanically extracted cellulose nanofibrils (mCNF), which have not been chemically modified, were used to create mechanically isotropic films. Crosslinking systems like carbodiimides, poly-functional aziridines, blocked isocyanates, and polyamide epichlorohydrin were added to chemically crosslink the nanocellulose films and improve the mechanical properties. The process to make the casting mixtures involved taking 3.1wt% mCNF, DI water, and a premeasured crosslinker solution to create a three to one ratio of solids for the final mixture of crosslinker to mCNF. Two cases were analyzed with each of the different crosslinkers: one with a viscosifier and one without to determine the crosslinking compound. The …

English Writing Centers In China: Opportunities, Challenges, And Paths Forward, Bradley Hughes, Jingtian Zhang Apr 2025

English Writing Centers In China: Opportunities, Challenges, And Paths Forward, Bradley Hughes, Jingtian Zhang

The Writing Center Journal

English writing centers at Chinese universities present a fascinating paradox. On one hand, the number of universities with writing centers and the professional interest in writing centers in China have grown steadily over the past two decades. But on the other, the number of centers is still modest and only a few centers have had a significant influence on the culture of writing on their campuses, which is surprising given the vast number of universities in China and the documented need for strengthening and expanding writing instruction in English. This international research study explores the current state of English writing …


We Should Promote Genai Writing Tools For Linguistic Equity, Nathan Lindberg Apr 2025

We Should Promote Genai Writing Tools For Linguistic Equity, Nathan Lindberg

The Writing Center Journal

In this essay, I suggest that we should embrace generative artificial intelligence (GenAI) writing tools, particularly chatbots (e.g., ChatGPT, Copilot, Claude), because they can enable linguistic equity by leveling the academic playing field for English as an additional language students. As writing experts, we can find ways to use this technology to enhance learning, and, since we know both student and faculty positions, we can help develop policies so such tools can be used effectively and ethically. Alternatively, we can ignore them and risk becoming irrelevant.


Somewhere In The Middle: Assistant Directors’ Leadership, Labor, And Power In Writing Centers, Keri L. Carter, John L. Carter Apr 2025

Somewhere In The Middle: Assistant Directors’ Leadership, Labor, And Power In Writing Centers, Keri L. Carter, John L. Carter

The Writing Center Journal

The position of writing center assistant director resides in the middle of the often blurry lines of hierarchy. While many writing centers advocate for team leadership, the fact remains that universities are steeped in bureaucratic tradition familiar to university leaders, students, and tutors. Assistant directors accomplish tasks that keep the day-to- day center functioning, yet these tasks equate to sometimes invisible work in the center and often invisible work in the university as a whole. Furthermore, research on assistant directors’ roles, labor, and identities is exceedingly limited. Thus, the purpose of this qualitative, phenomenological study is to understand how hierarchies …


Beyond Convenience: A Mixed-Methods Study Of Asynchronous Multimodal Tutoring And Its Impact On Understanding And Connection, Sohui Lee, Abigail Michelini Apr 2025

Beyond Convenience: A Mixed-Methods Study Of Asynchronous Multimodal Tutoring And Its Impact On Understanding And Connection, Sohui Lee, Abigail Michelini

The Writing Center Journal

Although traditional asynchronous tutoring is associated with text-based communication, writing centers are beginning to experiment with asynchronous multimodal tutoring with the assistance of accessible and interactive multimedia technologies and instructional platforms like VoiceThread. Using a mixed-methods approach of surveys and interviews of undergraduate students at a Hispanic Serving Institution (HSI), this study explores the potential benefits of asynchronous multimodal tutoring beyond access and convenience: We examine why students choose to submit their papers for asynchronous multimodal feedback, and whether they perceive that the multimodal aspect of the feedback improves their understanding and enhances their connection with tutors.

Department of Speech, Language, and Hearing Sciences Faculty Publications

Systemic hydration is known to promote optimal functioning of bodily systems—including the vocal folds. The impact of systemic dehydration on the biology of the vocal folds and the downstream effects of dehydration on voice output are not well understood. An in vivo rat model of systemic dehydration was employed to investigate vocal fold gene expression, histological changes, and acoustic changes in vocalization. Ultrasonic vocalizations (USVs) were recorded every day for 5 days (baseline), in male and female Long-Evans rats (N = 36, ages: 3–4 months) using an anticipatory reward paradigm. Next, rats were dehydrated (N = 18) using a published …

Unleaded Aviation Fuel: Assessing Stakeholder Perceptions And Preparing An Organization For Change, Ryan Guthridge, Nicholas D. Wilson, Brandon Wild Apr 2025

Unleaded Aviation Fuel: Assessing Stakeholder Perceptions And Preparing An Organization For Change, Ryan Guthridge, Nicholas D. Wilson, Brandon Wild

Journal of Aviation Technology and Engineering

Since the Clean Air Act of 1996 banned the use of leaded fuel for automotive applications, leaded aviation gasoline (AVGAS) has become one of the leading sources of lead pollution in the nation due to the volume of AVGAS consumed in general aviation applications (GAMA, 2019). The Federal Aviation Administration has recently recognized this concern with the establishment of the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative, which was formally established in February 2022 to foster an important campaign to research and inform the general aviation community on the process for transitioning to unleaded AVGAS. This essay seeks to inform …


Morphological Awareness: An Avenue For Improving Vocabulary, Word Recognition, Spelling And Reading Comprehension, Chenell Loudermill Apr 2025

Morphological Awareness: An Avenue For Improving Vocabulary, Word Recognition, Spelling And Reading Comprehension, Chenell Loudermill

Science of Reading

Learning requires the integration of many skills, with language development being a crucial foundational aspect. Language development across five domains-phonology (the sounds within a language), morphology (word structure/formation), semantics (word meaning), syntax (sentence structure/grammar), and pragmatics (use in varying contexts)-unequivocally supports the acquisition of reading and writing skills. Specifically, morphological knowledge is vital for improving vocabulary, word recognition, spelling and reading comprehension. This practice brief provides an overview of morphological awareness and derived words, provides a rationale for teaching morphological awareness, and instructional strategies supported by science.


Aha And Hmm: The Joy Of Writing Senryu, John J. Han Apr 2025

Aha And Hmm: The Joy Of Writing Senryu, John J. Han

KAUPA Letters

Senryu, a satiric and often humorous counterpart to haiku, emerged in mid-18th century Japan as a form of popular self-expression among the rising merchant class. Named after the poet and editor Karai Senryu, this genre focuses on human nature, social behavior, and everyday life rather than the seasonal themes central to haiku. Traditionally composed in a 5-7-5 syllabic structure, modern English-language senryu are often written in free style with fewer than 17 syllables. While frequently humorous, senryu can also capture serious aspects of human experience, including hardship and social issues. Unlike haiku, which encourages contemplation, senryu aims to evoke immediate …

Historical Imperative: A Key To Korean Unification, Paul Hong Apr 2025

Historical Imperative: A Key To Korean Unification, Paul Hong

KAUPA Letters

This essay explores the theory of historical imperative as a foundational framework for understanding Korean unification. It argues that Korea's unique and continuous national identity, resilience against external invasions, and modern aspirations for unity make unification an inevitable outcome of historical forces. The discussion highlights Korea's 5,000-year historical narrative, incorporating both documented dynastic transitions and the foundational Dangun legend (2333 BCE). While the Dangun legend is regarded as mythology by many historians, it remains a vital cultural and national symbol, reflecting Korea’s deeply ingrained sense of identity and continuity. The essay examines the survival of Korea’s identity through foreign invasions …
