Remaking A Monument: The Troubled Meaning Of Fascist Remains In Contemporary Spain, David Divita

Pomona Faculty Publications and Research

The Valley of Cuelgamuros, until recently known as the Valley of the Fallen, lies about 35 miles outside of Madrid. Inaugurated by the dictator Francisco Franco in 1959, this landmark comprises a vast underground basilica and houses the mostly anonymous remains of 34,000 Spaniards who died during the civil war (1936–1939) and its repressive aftermath. Since the early 2000s, the Valley has been a political lightning rod in a country that has long struggled with how to address the legacies of its authoritarian past. Ongoing debates among politicians, scholars, and journalists have revolved around the possibility of the Valley’s ‘resignification’ …

Introducing A Novel Figure Of Merit For Evaluating Stability Of Perovskite Solar Cells: Utilizing Long Short-Term Memory Neural Networks, Zahraa Ismail, Ahmed Alali, Mahmoud Ashraf, Ahmad Muhammad, Sameh O. Abdellatif

Electrical Engineering

This study introduces a novel figure of merit for evaluating the stability of perovskite solar cells (PSCs) by employing advanced Long Short-Term Memory (LSTM) neural networks to investigate degradation mechanisms. By harnessing the power of artificial intelligence and data analytics, we analyzed extensive datasets encompassing PSC parameters, experimental results, and environmental conditions, revealing critical insights into the degradation patterns affecting cell performance over time. Our findings indicate that the LSTM model effectively captures and predicts the complex relationships between key design parameters—efficiency, fill factor, and open-circuit voltage—and degradation-induced changes in PSCs. Specifically, we identified three degradation coefficients associated with the …

Influence Of Inselbergs On Bat Diversity In Afrotropical Ecosystems, Amanda Lee Grunwald

Dissertations and Theses

Humans are altering biological communities on local to global scales, driving profound changes in biodiversity and ecosystem functioning. However, significant gaps and biases in biodiversity data hinder our understanding of ecosystem interactions, making it challenging to develop effective, data-driven policies to protect remaining biodiversity. Bats, the second most species-rich groups of mammals, have a global distribution, and perform a broad array of vital ecosystem functions. Their diversity peaks in the tropics, where they often constitute more than 50% of mammal species diversity. The Afrotropics host substantial bat diversity, yet have historically been perceived as having lower species richness compared to …

Male Sexual Struggles: A Healing Journey, Todd E. Henley

Doctor of Leadership

My Need Problem or Opportunity (NPO) is that Christian men who commit adultery or engage in pornography are in desperate need of help to heal and be restored by the churches in Parkesburg and Coatesville, Pennsylvania.

One key insight from my research is that churches have continuously struggled to support the men in their congregations as they navigate the challenging journey of healing from issues like pornography and adultery. Through the perspectives of my stakeholders, it became evident that many men often remain unaware of how their past experiences impact their current struggles. Additionally, many carry a deep sense of …

Diarrhea is the predominant symptom of acute gastroenteritis resulting from enteric infections and a leading cause of death in infants and young children. However, the role of the host response in diarrhea pathogenesis is unclear. Using rotavirus and neonatal mice as a model, we found that oral inoculation of UV-inactivated replication-defective rotavirus consistently induced watery diarrhea by robust activation of cytosolic double-stranded RNA sensing pathways and type III interferon (IFN-λ) secretion. Diarrhea was significantly diminished in mice lacking the IFN-λ receptor. Mechanistically, IFN-λ signaling downregulates the expression of Dra, a chloride and bicarbonate exchanger, which contributes to reduced water absorption. …

Continuous Exposure To An Aversive Mixture: A Means Of Maintaining Aversion In Sheep Averted To Geigeria Ornativa O. Hoffm. (Vermeerbos) - An Assessment, Leendert D. Snyman

Poisonous Plant Research (PPR)

Establishing aversion to Geigeria ornativa only lasts for some time, after which the induced aversion disappears and sheep start eating G. ornativa again. This behavior is aggravated by the social influence of non-averted sheep in mixed grazing situations. Exposing sheep continuously to a so-called “aversive mixture”, containing an aversive substance (lithium chloride) and the sensory characteristics of the plant (hexane extract of G. ornativa) mixed with a tasty meal (maize meal), following an initial aversion treatment, resulted in sustained aversion to G. ornativa in the field. This method proved to be applicable to mixed grazing situations with averted and …

Control Of Clostridioides Difficile Virulence And Physiology By The Flagellin Homeostasis Checkpoint Flic-Fliw-Csra In The Absence Of Motility, Duolong Zhu, Katherine J Wozniak, Firas Midani, Shaohui Wang, Xingmin Sun, Robert A Britton

Faculty, Staff and Students Publications

Mutations affecting Clostridioides difficile flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving fliC, fliW, and csrA, which creates a feedback system to regulate flagella production. Through genomic analysis of C. difficile clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene fliC and regulatory gene fliW. We therefore investigated the roles of fliC, fliW …

Tuberculosis (TB) remains a significant public health challenge worldwide. Currently, Bacillus Calmette-Guerin (BCG) is the only vaccine available for TB prophylaxis. However, the efficacy of the BCG vaccine against adult pulmonary TB is considered inconsistent. This condition encourages researchers to look for more effective options, such as subunit vaccines. This condition requires the development of a more effective subunit vaccine to protect active TB in productive and adult ages. There is an urgent need for more effective vaccines, as the Bacillus Calmette-Guérin (BCG) vaccine currently available has inconsistent efficacy and is only partially effective in adults. Bio-immunoinformatics, an interdisciplinary field …

Articulated Robot Path Planning Based On Hybridization Of Adaptive ‎Dimensionality Algorithm And Grey Wolf Optimizer In Dynamic Environments, Noor Kadhim Ayoob‏, Ali Hadi Hasan

Karbala International Journal of Modern Science

A new method was developed to plan a path for a robotic articulated vehicle using the Grey Wolf Optimizer (GWO) ‎and Adaptive ‎Dimensionality (AD)‎. Existing studies in robotics path planning ignore the differences between robots in terms of size and flexibility and allocate a single cell to the robot regardless of the mentioned factors. Since the articulated robotic vehicle is longer than obstacles moving in the environment, this study takes into account vehicle size and flexibility in path planning by adapting the number of cells allocated to the robotic vehicle to contain the vehicle parts while performing different movements. Considering …

Ras El-‘Amud, Jerusalem: Faunal Remains From The Intermediate Bronze And Middle Bronze Age Settlement, Nimrod Marom

Qadum: Journal of Excavation Reports from Israel

The small faunal assemblage from Ras el-‘Amud provides insights into the economic strategies of a rural settlement during a period of urban growth. A shift from a self-sufficient goat and pig economy to a specialized sheep-focused one is observed, likely driven by urban demand. Analysis of caprine skeletal remains suggests consumption patterns and potential ritualistic practices. The Middle Bronze IIA village exhibits a decrease in butchery waste, possibly due to changes in spatial organization or waste disposal practices. The assemblage offers valuable insights into the economic and social dynamics of rural settlements during the Middle Bronze Age.

Flapping Dynamics And Wing Flexibility Enhance Odor Detection In Blue Bottle Flies, Naeem Haider, Zhipeng Lou, Chengyu Li

Faculty Scholarship

One of the most ancient and evolutionarily conserved behaviors in the animal kingdom involves utilizing wind-borne odor plumes to track essential elements such as food, mates, and predators. Insects, particularly flies, demonstrate a remarkable proficiency in this behavior, efficiently processing complex odor information encompassing concentrations, direction, and speed through their olfactory system, thereby facilitating effective odor-guided navigation. Recent years have witnessed substantial research explaining the impact of wing flexibility and kinematics on the aerodynamics and flow field physics governing the flight of insects. However, the relationship between the flow field and olfactory functions remains largely unexplored, presenting an attractive frontier …

Necrosis Drives Susceptibility To Mycobacterium Tuberculosis In Polg(D257a) Mutator Mice, C J Mabry, C G Weindel, L W Stranahan, Jordyn J Vanportfliet, J R Davis, E L Martinez, A Phillip West, K L Patrick, R O Watson

Faculty Research 2025

The genetic and molecular determinants that underlie the heterogeneity of Mycobacterium tuberculosis (Mtb) infection outcomes in humans are poorly understood. Multiple lines of evidence demonstrate that mitochondrial dysfunction can exacerbate mycobacterial disease severity, and mutations in some mitochondrial genes confer susceptibility to mycobacterial infection in humans. Here, we report that mutations in mitochondria DNA (mtDNA) polymerase gamma potentiate susceptibility to Mtb infection in mice. PolgD257A mutator mtDNA mice fail to mount a protective innate immune response at an early infection time point, evidenced by high bacterial burdens, reduced M1 macrophages, and excessive neutrophil infiltration in the lungs. Immunohis tochemistry reveals …
