Selection Of Phase Change Materials For Asphalt Pavement Based On Molecular Dynamics Simulation, Liu Fujun, Tian Xin, Liang Meichen, Guo Meng

Journal of China & Foreign Highway

Phase change materials (PCMs) have significant application potential in temperature regulation for asphalt pavements. To select suitable PCMs for road applications, this paper utilizes molecular dynamics simulation to analyze the molecular behaviors of lauric acid and polyethylene glycol (PEG). Experimental studies were conducted to validate the simulation results. The results show that molecular dynamics simulation provides an efficient and convenient method for comparing the performance of PCMs. PEG outperforms lauric acid in terms of molecular density, cohesive energy density, solubility parameters, and thermal conductivity, making it more suitable as a phase change material for asphalt pavements.

Study On Alkali Excitation Mechanism Of Large Dosage Slag Fine Powder, Mei Yang

Journal of China & Foreign Highway

To reveal the alkali excitation mechanism of high-dosage slag, this paper combines a three-factor, three-level orthogonal design with macro- and micro-performance tests and microstructure analysis. The effects of different activators, including Ca(OH)2, Na2SiO3, Na2SO4, and CaSO4, in single and dual combinations on the initial and final setting times, pore solution pH, and strength of concrete were explored. The results show that the impact on the strength of hardened paste of composite cementitious materials is ranked as: activator type > dosage > dual-mix ratio. The optimal dual-mix dosage is 4%, with the best combination being Ca(OH)2 and Na2SiO3 at a ratio of 5:1. …

Study On Microstructure Of Asphalt Modified By Oil‐Coal Blend, Guo Pengfei, Zhou Xinfeng

Journal of China & Foreign Highway

To investigate the microstructure and modification mechanism of asphalt modified with oil-coal blend, SK-90# asphalt was mixed with 5%, 10%, 15%, 20%, and 25% (external blending method) oil-coal blend to produce modified asphalt. The performance and microstructural changes of the modified asphalt were analyzed using contact angle testing, infrared spectroscopy, cross-sectional SEM, and X-ray photoelectron spectroscopy. The results show that the oil-coal blend exhibits good compatibility with asphalt. During the modification process, esterification reactions occurred, resulting in a decrease in hydroxyl-containing aromatic compounds and an increase in carbonyl-containing aromatic compounds. Macroscopically, the oil-coal blend-modified asphalt demonstrated excellent high-temperature performance.

Analysis Of Expressway Routine Maintenance Performance Management Based On Dea, Li Yuhuan, Shi Xiaoli, Gao Nan

Journal of China & Foreign Highway

To allocate maintenance resources efficiently and improve management levels, this paper examines the maintenance performance and improvement strategies of routine maintenance projects for 23 expressways in Shaanxi Province using 2018 operational maintenance data and data envelopment analysis. The results show that for some inefficient subsidiaries, traditional radial- and slack-based performance improvement methods are challenging and impractical in the short term. Therefore, a scenario-dependent model-based long-term incremental improvement strategy is proposed. By leveraging relative improvement values, this strategy enables phased improvements for inefficient subsidiaries. It provides a feasible approach for subsidiaries to set lower short-term performance improvement targets while achieving gradual …

Is My Prescription Ready Yet? A Qualitative Examination Of Patients' Understanding Of The Prescription Filling Process In Community Pharmacies, Maria Sallee

Honors Theses

Long lines at the pharmacy can frustrate patients. Consequently, patients becoming frustrated can add stress to an already overworked pharmacy. Without knowing what patients understand about the often complicated prescription filling process at community pharmacies, it can be difficult for pharmacists and pharmacy technicians to communicate the reason behind any delays in patients receiving their medication. To learn what patients understand about the prescription filling process, fifteen interviews were conducted over the phone after mailing recruitment flyers to members of a diabetes research collaborative in North Mississippi. The interviews revealed that while patients have a positive relationship with their pharmacists, …

The Effect Of Cannabinoids And Terpenes On The Activation Of Hmc3 Microglial Cells, Mohamed Marzouk

Honors Theses

Life expectancies of people living with HIV have significantly lengthened due to the availability of antiretroviral therapies. Despite their ability to increase survival, these treatments do not “cure” HIV, nor do the stop the onset of neurological symptoms associated with infection, termed neuroHIV. NeuroHIV describes a myriad of neurological impairments including mood disorders (depression and anxiety), cognitive impairment, neuropathic pain, and motor disinhibition that reduce quality of life for people living with HIV. Mechanistically, the neurological impairments may involve actions of neurotoxic proteins directly produced by the virus. One of these proteins that has been well-characterized is the HIV trans …

Monitoring American Federalism: The Overlooked Tool Of Sounding The Alarm Interposition, Christian G. Fritz

Faculty Scholarship

One key feature of the U.S. Constitution – the concept of federalism – was unclear when it was introduced, and that lack of clarity threatened the Constitution’s ratification by those who feared the new government would undermine state sovereignty. Proponents of the new governmental framework were questioned about the underlying theory of the Constitution as well as how it would operate in practice, and their explanations produced intense and extended debate over how to monitor federalism.

Challenging The "Unexceptional": Marguerite Of Provence, Thirteenth-Century Queenship, And Power, Katie Despeaux

History ETDs

Marguerite of Provence, wife to Saint Louis IX of France, has long been overlooked or negatively characterized by historians. Due to the unique circumstances of her mother-in-law’s political reach and her sister’s role as queen of England, Marguerite was limited by her husband and his court in her access to power. Traditionally understood as a passive queen, Marguerite’s expression of power through motherhood, curated images, and emotional performance can be better understood through Theresa Earenfight’s paradigm of gender and power. In a series of comparisons between Marguerite and her mother-in-law, sister, and Egyptian counterpart during the Seventh Crusade, Marguerite’s role …

Meqtl Mapping In The Genoa Study Reveals Genetic Determinants Of Dna Methylation In African Americans, Lulu Shang, Wei Zhao, Yi Zhe Wang, Zheng Li, Jerome J Choi, Minjung Kho, Thomas H Mosley, Sharon L R Kardia, Jennifer A Smith, Xiang Zhou

Faculty, Staff and Student Publications

Identifying genetic variants that are associated with variation in DNA methylation, an analysis commonly referred to as methylation quantitative trait locus (meQTL) mapping, is an important first step towards understanding the genetic architecture underlying epigenetic variation. Most existing meQTL mapping studies have focused on individuals of European ancestry and are underrepresented in other populations, with a particular absence of large studies in populations with African ancestry. We fill this critical knowledge gap by performing a large-scale cis-meQTL mapping study in 961 African Americans from the Genetic Epidemiology Network of Arteriopathy (GENOA) study. We identify a total of 4,565,687 cis-acting meQTLs …

Looking Back…There Is A Direction Home, Ioannis Galanopoulos-Papavasileiou

All Works

The article offers a rereading of Scorsese’s “No Direction Home” (2005, 2016,). The film replaces D. A. Pennebaker’s famous cinema verité, observational documentary “Don’t Look Back” (1967) about Dylan’s 1965 tour in Great Britain, which has proved, as years have passed, to be insufficient to convey the full story of Dylan’s personality behind his artistry. The article’s purpose, however, is not to cross-analyze the latter two documentaries. Instead, it provides a closer analysis of “No Direction Home” and explains how and why Dylan appears more appropriately different in this 2005 to 2016 production, while revealing the Scorsese–Dylan connection and commenting …

A Modified Dbt-Informed Art Therapy Group Curriculum With A Focus On Neurodiversity Acceptance, Megan Moyer

Art Therapy Counseling Final Research Projects

Historically, therapy methods made to support neurodivergent individuals have been focused on reducing “challenge behaviors” and modifying behavior to societal standards. Simultaneously, many behavior modification therapies neglect the emotional well-being of the individual. As neurodiversity grows to be accepted as an aspect of diversity, so too must therapy methods change to promote skill building in line with the cultural values and strengths of neurodivergent individuals and promote social-emotional well-being. This group therapy curriculum poses as one such possibility to this change by utilizing DBT and Art Therapy in a group psychoeducation format.

Cenabis Bene: A Culinary Odyssey Through Apicius, Kathryn Atkinson

Honors Scholar Theses

Apicius is the sole surviving cookbook from classical antiquity; as such it is invaluable for what it tells us about ancient feasting customs. Yet the gluttony typically associated with classical antiquity has no place in Apicius beyond the art that is inherently associated with food; we are not so much given a seat at the cena (dinner) as we are led into the kitchen, handed an apron, and instructed to cook. This critical analysis explores each recipe not only on the surface—i.e., examining the ingredients and recreating selected recipes—but also on a deeper level, lifting food above its concrete reality …
