Applied Environmental Research

The soil remains the largest carbon sink, the capacity of which varies spatiotemporally and with anthropogenic activities, with implications for carbon dioxide (CO2) emissions and associated global warming. Despite the increasing popularity of organic amendments in the ecologically and anthropoculturally diverse farming systems of tropical Africa, manure-induced CO2 emissions in this region with high soil-carbon-sequestration potential are poorly documented. This study assessed seasonal CO2 emissions from poultry manure-amended sandy-clay-loam and sandy-loam soils in the Rainforest-Savannah and Southern Guinea Savannah zones, respectively, of Nigeria. Following manure application at 3 rates (0, 10, and 15 t ha-1), soil samples were collected during …

The Structure, Dynamics, And Impact Of An Interbacterial Weapon Encoded By Human Gut Bacteria, Casey John Latario

Dartmouth College Ph.D Dissertations

The human gut is densely colonized by diverse bacteria. Over a human’s growth, the GI tract becomes a dynamic community that is subjected to a continual in-flow of nutrients and would-be colonizers and an out-flow of microbes and waste products. Despite these dynamics, the bacterial community often displays stability, with particular strains persisting over decades. These stable colonizers have evolved mechanisms to bolster their colonization, resist disruption by other microbes, and persist through environmental flux.

Both interbacterial competition and horizontal gene transfer (HGT) contribute to colonization and survival within the GI tract. A major mechanism for interbacterial competition is the …

Mansoura Engineering Journal

Production of concrete results in high CO₂ emissions, high energy demand, and consumption of various raw materials; however, it is one of the most widely used materials in construction to date. Therefore, researchers aim to minimize the impact of concrete production through various methods, such as introducing sustainable sources of materials that can be used in concrete. For instance, agricultural waste materials can be used as partial cement replacement. This study presents a comprehensive data-driven analysis of the effects of POFA on the properties of normal-strength concrete. By synthesizing a database of 196 experimental datasets from existing literature, three …

Federated And Explainable Spiking Neural Networks For Fair And Privacy-Preserving Nail Disease Diagnostics, Ch Pavani Reddy, Krishnanaik Vankdoth

Mansoura Engineering Journal

Automated nail disease diagnostics provide a non-invasive pathway for identifying underlying systemic health conditions; however, conventional centralized deep learning approaches often raise concerns related to privacy, fairness, and interpretability. Although the original NeuroNail-SNN framework demonstrated an energy-efficient and edge-ready diagnostic solution, its broader clinical adoption remained limited by unresolved trust, transparency, and ethical considerations. In this study, we propose the Federated and Explainable NeuroNail-SNN, which extends the original spiking neural architecture by integrating federated learning (FL), explainable artificial intelligence (XAI), fairness evaluation, and uncertainty quantification within a unified framework. Federated learning enables decentralized model training across hospitals and mobile clinics …

Examining The Factor Structure And Subgroup Invariance Of The Deliberate Denial Of Disordered Eating Behaviors Scale, Lindsay Howard, Sage Hawn, Kayla D. Pitchford, Riley Mcgrath, Aubri Farniok, Arturo Sesma, Kristin E. Heron

Psychology Faculty Publications

The denial, concealment, or omission of disordered eating behaviors has received limited attention in the eating disorder literature, partly due to the lack of reliable and valid measures. This study re-examined the factor structure of the Denial of Disordered Eating Behaviors Scale (DDEBS-12) and tested measurement invariance across gender identity, racial identity, and levels of disordered eating in a non-clinical undergraduate sample (N = 3285). Confirmatory factor analyses did not support the original unidimensional structure. Instead, a seven-item model assessing denial of dietary restriction demonstrated the best fit and was renamed the DDEBS-restriction. The revised scale showed good internal consistency …

To examine effects of a multilevel, religiously-tailored HIV testing intervention, Taking It to the Pews (TIPS), on receipt of HIV testing with African American church-affiliated populations, 14 African American churches (N = 1,491) were randomized to TIPS or a multilevel, non-tailored HIV education attention-control arm in a cluster-randomized trial (Kansas City urban area, 2013 to 2019). Receipt of an HIV test was examined using objective data and participant self-reports (last 12 months), including self-reported exposure to intervention components. Overall, 471 HIV tests were completed; TIPS intervention churches conducted significantly more tests than controls (339 versus 132, p = 0.003). Also, …

Efficacy Of Endophytic Fungi In The Management Of Spoladea Recurvalis (Lepidoptera: Crambidae) On Amaranth (Amaranthus Dubius), Druscilla Obonyo Nyamamba

All Master’s Theses

Amaranth is a Traditional African Vegetable (TAV) that in recent years has gained global popularity due to its exceptional nutritional, medicinal and economic attributes. However, its production is significantly limited by insect pest infestations, mainly lepidopteran defoliators. Spoladea recurvalis, commonly known as Hawaiian beet webworm has been reported as the major pest that feeds voraciously on the leaves leading to substantial yield losses of up to 100% under severe pest infestation. Chemical control remains a widely used method for the management of S. recurvalis. The use of fungal endophytes has emerged as a promising, sustainable and eco-friendly alternative to …

Differing Circulating Microrna Profiles Of Long-Lived Polish Populations, Fabrizzio Lijeron-Herrera

Honors Undergraduate Theses

Exceptional longevity, defined as a lower biological age relative to chronological age and maintenance of functional capacity or a slowing of functional decline, is a phenotype most readily observed in centenarians and nonagenarians. These individuals exhibit a phenomenon known as compressed morbidity, spending substantially less time in poor health compared to younger elderly populations, thus representing a unique human model of delayed aging. Circulating microRNAs (miRNAs), potent post-transcriptional regulators of molecular pathways, have emerged as important modulators of aging-related pathways; however, no study has comprehensively profiled miRNAs from serum in long-lived individuals from Central Europe. In particular, Polish populations present …

Animal and Food Sciences Faculty Publications

Legume supplementation has been shown to mitigate fescue toxicosis in beef cattle. However, no studies have directly compared the use of soybean-based feeds to alleviate symptoms of fescue toxicosis under controlled environmental heat and equalized feed intake. The objectives were to evaluate the effects of soybean hulls, whole soybeans, or soybean meal (SBM) supplementation on the mitigation of vasoconstriction, heat stress, and inflammatory responses in beef cattle during fescue toxicosis. Ten ruminally-cannulated Angus × Holstein steers were used in a 5 × 10 Latin rectangle design. Five treatments were evaluated: 1) non-toxic endophyte-infected tall fescue seed (NTE), 2) toxic endophyte-infected …

Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …
