Recovery Of High Energy-Value Materials From Mine Wastewater, Zainab Nasrullah

Graduate Theses & Non-Theses

The increasing global demand for high-energy-value materials (HEVM), such as rare earth elements (REEs), copper (Cu), nickel (Ni), cobalt (Co), and lithium (Li), coupled with their limited availability and environmental concerns associated with traditional mining methods, necessitates the development of alternative and sustainable recovery strategies. Wastewater streams from industrial processes, mining operations, and electronic waste treatment represent untapped reservoirs of these valuable materials. Research is proposed to develop sustainable, cost-effective, and scalable methods for selectively recovering HEVM from mine wastewater (Berkeley Pit, Montana). Two innovative approaches, the adsorption process using functionalized adsorbent and solvent extraction (SX) using organic or hydrophobic …

Aqueous Geochemistry Drives Microbial Cu, Fe, And Zn Uptake Rates In Yellowstone, A Continental Hydrothermal System, Eva Carolina Andrade-Barahona

Graduate Theses & Non-Theses

Microbial uptake of trace metal cofactors such as copper (Cu), iron (Fe), and zinc (Zn) is governed by biogeochemical processes in hydrothermal systems where metal bioavailability varies widely. In situ microbial metal uptake rates were quantified by applying metal stable isotope probing (MSIP) in the Yellowstone hydrothermal system across diverse geochemical conditions in hydrothermal springs. The findings in these studies revealed that pH exerts a dominant influence on microbial copper uptake rate, also enhanced by increased Cu²⁺ ion availability and dissolved oxygen. Microbial iron uptake, in contrast, displayed a broad tolerance to environmental variability, occurring across a pH range of …

Functional Impact Of Single Nucleotide Polymorphism Rs4129009 (Ile775val) On Human Toll-Like Receptor 10, Audrey N. Koti

Biology Student Research

Toll-like receptors (TLRs) are a subclass of pattern recognition receptors within the

innate immune system that detect pathogen-associated and danger-associated molecular patterns,

thereby initiating host defense responses. The human TLR family comprises ten receptors (TLR1

– TLR10), each recognizing structurally conserved microbial motifs such as bacterial

lipoproteins and viral nucleic acids. The ligand specificities, adaptor protein recruitment, and

downstream signaling cascades have been well-characterized for TLR1 – TLR9, which

predominantly engage MyD88- or TRIF-dependent pathways to activate pro-inflammatory

transcription factors including NF-κB. In contrast, the ligand specificity and intracellular

signaling mechanisms of TLR10 have yet to be fully elucidated. Emerging …

Looking At Labels, Examining Values: Knowledge, Narrative, And Multilingualism In American Art Museums, Mary Mitchell

Masters Theses

Object labels are key components of the knowledge production networks in American museums. But despite their sustained use in the Western museum field since the late nineteenth century, museum labels are not frequently regarded as valuable sources in scholarship on museum history and practices. In this thesis, I reposition labels in art museums as objects of value that should be studied for their important role in producing and disseminating knowledge. What can we learn about art museums by looking closely at their labels—specifically about those institutions’ values? How do labels reveal the hierarchies of value that art museums construct between …

Subculture And Identity As An Escape From The Societal Norms Of Power Imbalance And Authoritative Abuse, Sarah Goldberg

Master's Theses

By definition, a “bolthole” is an animal’s escape or burrow; or, a person’s escape or place of refuge. It also connotes construction, building, even sculpture - relating proletarian materials to themes of working-class labor and the need for escape. Through sculpture, installation, drawing, and oil painting, Bolthole as a body of work examines power imbalance as a societal norm, and identity and subculture as a rejection of the influence of capitalist institutions. Animal symbolism is used in combination with figurative work and portraiture, directly comparing power imbalances between humans to those in nature; such as predator and prey, parent and …

The Interplay Of Morphology, Syntax, And Semantics In Kuria Verb Extensions Within The Mara Region, Mary Charwi

Journal of Humanities and Social Sciences

Verb extension morphological affixes that significantly alter verb meaning are a defining characteristic of Bantu languages. This paper investigates the morphosyntactic behaviour, semantic implications, and functional roles of extensions within Kuria, a Bantu language of Tanzania. The study adopts Hyman’s morphocentric approach, specifically the CARP template (Causative-Applicative-Reciprocal-Passive), as its foundational framework to test whether Kuria adheres to this pan-Bantu default ordering. The data were collected in Tarime District (2014-2015) using a mixed methods approach, comprising questionnaires, semi-structured interviews, and video stimuli with 13 rural and urban speakers, and text analysis (the Kuria Bible). Through rigorous morphosyntactic parsing, the analysis reveals …

The Syntax And Semantics Of Reciprocal Constructions In Chibarwe: A Lexical Mapping Account, Tendai Chirimaunga

Journal of Humanities and Social Sciences

Bantu languages have a robust structure, which is usually stated to be agglutinative, accommodates affixations of a wide range of morphemes both as prefixes (to the left of the root), as well suffixes (to the right of the root) before placing the terminal vowel. In their verbal morphology, the reciprocal is one of the many derivational affixes that have, however, not gained similar prominence as the study of the applicative and the causative construction. The thrust of this study is to investigate the syntax and semantics of reciprocal constructions in ChiBarwe, a marginalised cross-border language spoken in Zimbabwe and Mozambique. …

Effects Of Integrated Biological And Chemical Fertilization On Pecco And Banji Shoot Development In Tea Plants, Intan Ratna Dewi Anjarsari, Muhammad Raihan Abdillah Farros, Santi Rosniawaty

Jurnal Kultivasi

Tea productivity and quality are largely determined by shoot structure, particularly the balance between pecco shoots (tender buds and young leaves) and banji shoots (older, less productive shoots). Conventional reliance on inorganic fertilizers often enhances overall growth but does not necessarily improve shoot structure, while biofertilizers alone provide limited nutrient availability. This study aimed to evaluate the effects of combining microbial-based liquid biofertilizers with inorganic fertilizers on the structure of tea shoots. The experiment was carried out on seed-derived tea plants using a randomized block design with several fertilization treatments, including sole biofertilizer, sole inorganic fertilizer, and their combinations.

A Rodent Model Of Enhanced Anticipation Of Positive Events: Sex-Specific Modifications In Cognitive Bias And Emotional Resilience, Sarah C. Hartvigsen, Megan Hooper, Olivia Harding, Evelyn Barringer, Aditya Narayanan, Brendan Crockett, Yulia Shatalov, Paean Luby, Braden Wixted, Molly Kent, Kelly Lambert

Psychology Faculty Publications

While it is known that chronic unpredictable stress and negative events adversely affect neurobiological outcomes, much less is known regarding the neurobiological impact of positive emotions such as chronic anticipation of appetitive events. From a translational perspective, an enhanced understanding of the impact of extended exposure to positive emotions may provide novel insights into effective non-pharmacological, behavior-based approaches to enhance mental resilience. Here, we investigate a novel rodent model of chronic Unpredictable Positive Event Response (UPER) training in male and female Long Evans rats to examine behavioral, neural, and endocrine effects of enhanced anticipation of positive events. Rats were exposed …
