Mechanical Engineering

Nanotechnology has been a promising technology over the years. Carbon nanotubes (CNTs) are one of the principal technologies that are developed in the nanotechnology sector. This study investigated the implementation of CNTs as additives in automotive lubricants, focusing on their impact on performance metrics. The dispersion of CNTs in lubricants is influenced by several factors, the most critical of which is the dispersion stability. Key findings include improved dispersion stability of CNTs in lubricants through adding surfactants like oleic acid, which effectively managed the aggregation issues. The CNT-enhanced lubricants exhibited superior tribological, thermophysical and rheological properties compared to the bare …

Developing A Digital Phenotype To Subdivide Adult Immunosuppressed Covid-19 Outcomes Within The English Primary Care Sentinel Network, Debasish Kar

Peninsula Medical School

Background: Adults classified as immunosuppressed have beendisproportionately affected by the COVID-19 pandemic. Compared to theimmunocompetent, certain patients are at increased risk of suboptimal vaccineresponse and adverse health outcomes if infected. However, there has beeninsufficient work to pinpoint where these risks concentrate within theimmunosuppressed spectrum; surveillance efforts typically treat theimmunosuppressed as a single entity, leading to wide confidence intervals. Aclinically meaningful and computerised medical record (CMR) compatiblemethod to subdivide immunosuppressed COVID-19 data is urgently needed.Methods: We conducted a rapid scoping review into COVID-19 mortality acrossUK immunosuppressed categories to assess if differential mortality risk was aviable means of subdivision. We converted the …

Research outputs 2022 to 2026

Chickpea (Cicer arietinum L.) is the second most widely grown legume crop after soybean. Here, we measured the macronutrients and performed proteome profiling of eight chickpea cultivars using two complementary protein extraction solvents. The total protein, starch, and soluble sugar contents significantly differ between cultivars, and we quantified 2434 and 1809 proteins, respectively, from urea- and water-based extraction solvents using a data-independent acquisition approach. The proteome-level differences can vary from 9-25% for the urea-extracted proteins, and the storage protein abundances significantly differed between the cultivars, where legumin content was detected as the highest, followed by vicilin and albumin. Fifty common …

Style, Nonetheless. Eight Good Reasons To Reject The Notion Of Style; Three Reasons To Use It Nonetheless, Béatrice Joyeux-Prunel

Artl@s Bulletin

This article examines why art historians have distanced themselves from the concept of “style” since the 1960s. It draws on the critiques of Meyer Schapiro and Ernst Gombrich, which were often cited and reinterpreted by post-constructivist and decolonial historiographies since the 1990s. It identifies eight key factors: variability of definitions, normative applications, tendency towards formalism, evolutionary implications, oversimplification, historical ties to racist assumptions, hierarchical effects, and modern Western biases. However, the article argues for distinguishing the cognitive relevance of “style” from its problematic uses, exploring its potential application within a socio-historical framework.

Review Of The Diagnosis, Pathophysiology, And Treatment Of Naegleria Fowleri-Induced Primary Amoebic Meningoencephalitis, Terrance Zhang

MCB Articles

Naegleria fowleri is a thermophilic, ubiquitous, free-living amoeba, but is also known as the “brain-eating” amoeba. This is the etiological agent of a rare and fulminant waterborne disease known as Primary Amoebic Meningoencephalitis (PAM) that is acutely fatal in 90-99% of reported cases. Those who come into contact with infested waters are at risk of introducing the amoeba into their upper nasal canal, whence the trophozoite form is known to migrate along the olfactory nerve, through the cribriform plate, and enter the central nervous system. Although the exact pathogenesis of N. fowleri is not known, studies have demonstrated contact-dependent and …

Cross-National Prevalence And Legality Of Consanguinity & Its Implications For State Security, Emma Dart

Undergraduate Honors Theses

This thesis examines the impact of cousin marriage prevalence on state stability and the development and behaviors of terrorist organizations, with a special focus on the destabilization of states through the power of kinship networks. Cousin marriage, often intertwined with other social practices such as patrilocality and polygyny, creates an isolated power structure that reinforces the fraternal structure present in kinship networks. The kinship network then uses the power gained through the trust in the community to undermine the legitimate rule of law. This research emphasizes the importance of understanding cousin marriage and its contribution to state stability and finds …

Early Childhood Faculty Perspectives On Inclusion Of Antibias Curriculum Or Components In Preprimary Teacher Training Curriculum In The United States, Carlotta Conley

The purpose of this basic qualitative study was to examine early childhood education (ECE) community college faculty perspectives on the importance of and challenges with implementing antibias curriculum or components into preprimary education training. The conceptual framework was Smyth’s model of reflection and the Learning for Justice organization’s antibias framework. For this basic qualitative design, data were collected …

Flying Under The Radar: Navigating Through Frustrations, Tears, And The Politics Of The Liberal Arts Curriculum, Sandra Houghton

Theses and Dissertations

The elements and principles of art continue to highly influence curriculum in the typical art foundations class. The reduction of art and artmaking to their formal properties constricts a student’s ability to engage in real-life artist processes, and many important contextual meanings are lost. Consequently, art foundations curriculum derived from the elements and principles of art narrows the lens through which we create, teach, and talk about art. In my own experience as an art teacher, I have found that this approach limits my teaching and makes it difficult to fully and authentically understand the works of other artists and …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Superoxide dismutase enzymes are a major defense against superoxide, which is a potent reactive oxygen species. Misregulation of reactive oxygen species and subsequent neuronal damage are etiological hallmarks of neurodegenerative disease. Macrocyclic small molecules have offered inroads toward functional SOD1 mimics. Herein, we report a series of five tetra-aza macrocyclic ^RPy₂N₂ ligands, varied by 4-position substitution of the pyridine ring with both electron-donating (R = OMe) and withdrawing groups (R = Cl, I, and CF₃) to offer the first comparison to well-studied ^RPyN₃ congeners and other mimics in the literature. New ligands …

An In-Depth Investigation Into Yersinia Pestis Phages: Isolating A Yersinia Pestis Phage From Soil And Constructing A Comprehensive Phylogenetic Analysis Of Known Yersinia Pestis Phages, Jacqueline Chavez

All HCAS Student Capstones, Theses, and Dissertations

Yersinia pestis, the causative agent of the plague, has become increasingly resistant to many antibiotics; therefore, alternatives such as phage therapy are necessary. Phage therapy uses combinations of bacteriophages or phages, which are viruses that only infect bacteria. However, phages—especially Y. pestis phages —are severely understudied. Thus, this research has sought to specifically isolate a phage from soil that infects Y. pestis. There were 146 samples that were collected from across the US, focusing on those with reported cases of plague. These samples were enriched with Y. pestis to maximize the amount of potential phage that target Y. pestis. …

Systemic lupus erythematosus (SLE) is an autoimmune disease that more commonly affects African American people, although it is seen in people of all racial backgrounds. This condition is characterized by a dysregulated immune response resulting in widespread inflammation. Clinical manifestations caused by this inflammation include arthritis, anemia, cutaneous rashes, pleuritis, and nephritis. Treatment for SLE aims to reduce disease activity and maintain a state of low inflammation. In this regard, numerous treatments are used, such as hydroxychloroquine, glucocorticoids, and non-glucocorticoid immunosuppressants such as methotrexate. Related to these drugs resulting in significant adverse effects and being ineffective in controlling SLE symptoms …
