Performance Optimization Of Superfine Cement Through Composite Modification Using Coal-Based Solid Waste And Modifiers, Kang Zhipeng, Luo Yong, Xiao Diancai, Ren Shuai, Cai Zhiliang, Gao Xiang, Zhang Kunzhe

Coal Geology & Exploration

Objective Superfine cement-based grouting materials generally suffer from limitations including high bleeding rates, unfavourable rheological properties, poor stability, and strength retrogression. These issues can be mitigated by incorporating modifiers, which allows for the reutilization of coal-based solid waste while enhancing the performance of composite, superfine cement-based grouting materials. Methods Superfine cement-based grouting materials with different mixing ratios were prepared by using superfine cement as the basic material, fly ash (FA) and mineral fines (MFs) as primary admixtures, and modified bentonite, methyl cellulose ether (MCE), U-type expansive agent (UEA), and magnesium oxide (MgO) as modifiers. These grouting materials and pure superfine …

Mine Data Fusion Technology Based On Multi-Feature Joint Decision Making, Han Shanshan, Zhang Jifeng, Fan Tao, Liu Qiang, Song Xiaojiao, Qi Zhipeng, Zheng Hangzhou

Coal Geology & Exploration

Background In the field of geological exploration of coal mines, methods such as in-seam seismic exploration, the transient electromagnetic method, and audio-frequency electrical penetration offer unique technical advantages. However, each of these methods can only reflect a single physical property of a medium, suffering from limitations including the one-sidedness of information and the multiple solutions of interpretations, thus failing to adapt to the new situations of current coal mine exploration. Multi-source data fusion promotes a technological development by leaps from one-sided detection to comprehensive analysis through mechanisms of information complementation, feature enhancement, and field-source integration. Therefore, this technology can enhance …

Linguistic Evolution In The Light Of Ecolinguistics: A Reading Of Ibn Jinni’S Book “Al-Khasais”, Salwa Rajeh Mohammed Alabdali Alshareef

Journal of Arabic Sciences and Humanities

This study presents a descriptive reading of the ecological orientation implicit in the linguistic thought of Ibn Jinnī (d. 1002), as articulated in his work (Al-Khaṣāʼiṣ). It traces how language development is conceived in relation to environmental and social conditions, without imposing modern theoretical frameworks retrospectively. The study situates this heritage-based conception alongside contemporary discussions of the language–environment relationship, particularly the ecology of language proposed by Einar Haugen and the ecological models of language evolution developed by Salikoko S. Mufwene. Adopting a descriptive–analytical approach, the study shows that Ibn Jinnī conceptualizes linguistic variation as a natural consequence of differential social …

Al-Harbi’S Novel “Arab Rabbi” Between Self-Objectification And Gender Obfuscation: A Semiotic Reading, Ahmed Bin Hassan Aloush Madkhali

Journal of Arabic Sciences and Humanities

This study examines Ahmed Al-Harbi’s novel Arab Rabi as a narrative text that raises issues related to literary genre and textual identity, after it was reprinted three times consecutively under different titles and classifications without changing the text. The study focuses on analysing the thresholds of the text in the novel and their role in constructing meaning, and traces the mechanisms of subjectification and genre confusion in relation to the cultural and social contexts of narrative discourse. Using a semiotic approach based on Gérard Genette’s theory of thresholds and supported by cultural semiotics, the research analyses the title, literary genre, …

From Storybooks To Courtrooms: A Corpus-Based Descriptive Analysis Of Culture-Specific Translation Strategies In Saudi Arabia, Saad Salem Alshamrani

Journal of Arabic Sciences and Humanities

It employs a corpus-based descriptive approach to examine authentic published translations drawn from selected Arabic children's storybooks and official courtroom materials available through the Saudi Ministry of Justice. This approach enables the study to identify patterns in translators' strategies and the contextual factors that shape them. The analysis reveals that translators in children's literature predominantly employ adaptation, paraphrase, and explicitness to ensure accessibility and reader engagement. In contrast, legal translators favor literal translation and functional …

Food Reintroduction After Negative Ofcs In Pediatrics: Dietary Frequency And Caregiver Attitudes, Olivia Pietrantozzi

Honors Projects

Food allergies in pediatric populations have been gradually increasing in prevalence and present significant nutritional risks requiring strict dietary management and psychosocial challenges. Oral food challenges (OFCs) serve as a gold standard in diagnosing food allergies and determining whether allergenic foods can be safely reintroduced to an individual's diet. However, caregivers of children may still experience anxiety and barriers that delay the reintroduction of foods, which can limit diet diversity and increase the child's risk of future allergy development. This study looked to evaluate the dietary frequency of allergenic food reintroduction following negative OFCs, as well as to assess changes …

The study included the identification of spatial distribution patterns of public toilet locations in Muzdalifah. The study used a simple random sampling method to collect field data on public …

The Toll Of The Bridge: Affective Citizenship And The Negative Dialectic Of The `Promised Land' In Arab American Fiction, Muhammad Khaled Alatrash

Journal of Arabic Sciences and Humanities

Scholarship on Arab American literature frequently follows a linear decline from Mahjar-era optimism to the disappointments of post-9/11. This article complicates that trajectory by reading Khalil Gibran's The Broken Wings (1912) and Laila Halaby's Once in a Promised Land (2007) as stages of a negative dialectic—contradiction held in tension without resolution. Gibran envisions America as a sanctuary unreached by the hands of the thieves, where the self might be understood correctly rather than sorted into hostile categories. Halaby reveals how sanctuary becomes a checkpoint: inclusion demands permanent performance of harmlessness, and failure is punished not through formal exclusion but through …

Impact Of Human Disturbance On Moth Populations In Ecuador, Gianna Jones, Abbie Miller, Esther Frederickson, Grace Glerum

Science Seminar

Habitat disturbance in the temperate zone has been shown to negatively impact moth biodiversity and population size through a reduction in moth food resources and light pollution. Our study sought to understand how human activity impacts moth population numbers and diversity (# unique taxa) in the tropics. Specifically, we sampled moth population and diversity using light traps on two different nights in a disturbed habitat (Mera township, Ecuador) and on two nights at a nearby ecolodge situated in dense tropical forest. Significantly fewer moths were observed during trapping sessions in the township, and many fewer distinct taxa were noted when …

Patterns Of Moth Diversity In Relationship To Human Disturbance And Forest Type, Gianna Jones, Abbie Miller, Esther Frederickson, Grace Glerum

Science Seminar

Moths play a vital role in the health of tropical ecosystems, acting as important pollinators and food resources for a variety of species. Unfortunately, human habitat disturbance has been associated with declines in moth populations and diversity. To explore the impacts of habitat disturbance on taxonomic diversity in the tropics, we sampled moth populations at two different locations in the Pastaza Province (Mera township and an undisturbed forest at Tamandua Ecolodge). Though small in population (

Biodiversity And Diet Patterns: Environmental Impacts On Ecuadorian Birds, Holly Hylton, Fin Bolt, Gracyn Herbst

Science Seminar

The current biodiversity crisis is of great concern, particularly to bird species in temperate and tropical areas. We examined avian biodiversity patterns in Ecuador, one of the most bird-biodiverse countries in the world (1650+ species). In January 2026, birds were surveyed (visual and auditory) for 30 minutes on consecutive days in 4 different locations that differed in the degree of human development. As expected, species richness was much higher in undisturbed locations than disturbed locations. In addition, our comparison of dietary patterns between sites showed a much higher proportion of frugivorous and insectivorous species in areas with less human disturbance …

Silent Persuasion In The Classroom: Rethinking Student Silence As Rhetorical Agency, Deepa Silwal

Frontera Retórica Symposium

In most educational settings, rhetorical participation refers to the recognized ways people communicate and persuade. It is measured almost exclusively through verbal contribution, a norm that frames silence as disengagement or deficit. This assumption overlooks the communicative work performed through the body itself, particularly among students navigating linguistic, cultural, or institutional constraints. I ask: how might embodied silence be theorized as a form of rhetorical agency among students positioned at the margins of institutional power? I propose the concept of silent persuasion, which refers to rhetoric enacted not through speech but through the body's presence, posture, stillness, and restraint. Drawing …

A Single Administration Of Psilocybin Is Ineffective In Reversing Ptsd-Like Sequelae In A Rat Model Of Stress-Enhanced Fear Learning, Kylie M. King, Marisa J. Savini, Noelle M. Molnar, Evelynn J. Schneider, Savannah E. Straub, Joe Parker, Lillianna P. Puppel, Aleece K. Al-Olimat, Allison M. Bach, Phillip R. Zoladz

ONU Student Research Colloquium

Single treatments with psychedelics produce rapid, long-lasting antidepressant effects. Psychedelics may also exert anxiolytic effects and be useful in treating more complex psychiatric conditions, such as PTSD. However, less is known about the impact of these agents on PTSD-related symptoms. Thus, we aimed to determine whether a single administration of psilocybin could reverse PTSD-like sequelae induced by stress-enhanced fear learning in rats. Sprague-Dawley rats were placed in Context A (circular, white conditioning box) and exposed to several uncontrollable footshocks (Stress) or no footshocks (No Stress). The next day, the rats were placed in Context B (square conditioning box with clear …

Psilocybin And The Related Tryptamine, Norbaeocystin, Exert Acute Anxiogenic Effects That Depend On Sex, Marisa J. Savini, Kylie M. King, Noelle M. Molnar, Evelynn J. Schneider, Savannah E. Straub, Joe Parker, Lillianna P. Puppel, Aleece K. Al-Olimat, Allison M. Bach, Andrew Jones, Phillip R. Zoladz

ONU Student Research Colloquium

Single treatments with psychedelics have demonstrated rapid, long-lasting antidepressant effects. However, psychedelics often produce unfavorable psychoactive effects that could worsen existing psychological distress. Thus, we compared the effects of psilocybin and the related tryptamine, norbaeocystin, on anxiety-like behavior in male and female rats. In Experiment 1, rats were treated with 1 mg/kg psilocybin (PSIL), 1 mg/kg norbaeocystin (NOR), or vehicle 30 min before a 5-min trial on an elevated plus maze (EPM) or in an open field test (OFT). On the EPM, PSIL led to decreased open arm time and fewer arm entries in males and females. NOR led to …

Impact Of Caffeine On Participant Memory For A Stressful Experience And The Development Of Intrusive Memories, Jaycee L. Kirkland, Kaylina R. Mcclenen, Natalina E. Porter, Sarah M. Wood, Julia Gross, Madilyn E. Paphanchith, Kelsey M. Siereveld, Jasmine Ic Ifeakanwa, Caeden M. Gurganus, Koen N. Suzelis, Aiden J. Farrell, Boyd R. Rorabaugh, Phillip R. Zoladz

ONU Student Research Colloquium

Most individuals consume caffeine on a daily basis. Research has shown that caffeine stimulates the release of glucocorticoids and catecholamines and can enhance cognition. Caffeine also amplifies stress-induced increases in arousal and aggravates PTSD-like symptoms. Thus, we examined the impact of caffeine on memory for a stressful experience and intrusive memories related to that experience. Undergraduate students ingested caffeine or a placebo. Thirty minutes later, they were exposed to the Trier Social Stress Test (TSST; stress condition) or friendly-TSST (f-TSST; control condition), both of which were designed to enable participant memory for the experiences to be quantified. In each condition, …

Cultivating Home: Nepali Migrants And Gardening As Everyday Rhetoric, Menuka Gurung Lama

Frontera Retórica Symposium

Rhetorical knowledge is often discussed through formal institutions and textual traditions, leaving everyday community practices underexamined. This paper engages the theme “Rhetoric from the Margins” by examining how Nepali migrants’ gardening practices in Hooksett, New Hampshire produce knowledge outside dominant academic and institutional frameworks. I ask: How do Nepali migrants use gardening as a way of making meaning, sustaining memory, and cultivating belonging in unfamiliar environments? In what ways does gardening function as a rhetorical and epistemic practice through which migrants carry and transform land-based knowledge across borders? Rather than treating gardening simply as leisure or subsistence activity, I examine …
