Presentations Of Cutaneous Disease In Various Skin Pigmentations: Hidradenitis Suppurativa, Jamie Y. Choe, Henry Lim, Marshall Hall, Christian Scheufele, Dustin V. Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder characterized by recurrent deep-seated nodules and painful abscesses with scars, fistulae, and sinus tracts that predominately affect the intertriginous sites. Onset typically occurs soon after puberty. Depending on disease severity, HS can lead to varying levels of pain, disability, and disfiguration with significant impacts on quality of life. Hidradenitis suppurativa is diagnosed clinically, and no diagnostic tests are specific to the disease. Therefore, clinicians must have the knowledge and competence to identify the clinical features of HS accurately. The purpose of this report is to provide descriptions of characteristic clinical presentations …

Sebaceous Gland Heterotopia Of The Esophagus: A Rare Incidental Finding During Upper Endoscopy, Samuel Ramos, Margaret-Anne Huntley, Eric Vargas, Jignesh Parikh, Vania Zayat

HCA Healthcare Journal of Medicine

Esophageal heterotopic sebaceous glands (EHSG) are an extremely rare finding within the esophageal epithelium. These glands are typically benign, presenting as small, yellow-white plaques or lesions observed on endoscopy, often in the middle third of the esophagus. Esophageal heterotopic sebaceous glands are generally asymptomatic, and surveillance is not required. While their origin is unclear, proposed mechanisms include metaplastic transformation and congenital development. Recognition and histologic confirmation are essential to distinguish EHSG from other esophageal lesions and to avoid unnecessary interventions. We report the case of a 55-year-old man in whom multiple diminutive plaques were identified in the mid-esophagus during esophagogastroduodenoscopy …

Engineering and Technology Journal

The use of membrane separation and heterogeneous photocatalysis together appears to be an innovative way to remove long-lasting pollutants such as paracetamol (PCT) from water. To overcome the limited process by understanding hindering the practical deployment of solar-driven photocatalytic membrane reactors (PMRs), this study proposes a process-engineering-centered framework for a low-cost, integrated ceramic PMR. A laboratory-scale system was developed using inexpensive red clay ceramic membranes modified by immobilizing TiO₂ (P25) for paracetamol degradation under natural sunlight and ultraviolet irradiation. Unlike previous studies mainly focused on material development, this work evaluates the coupled effects of TiO₂ loading, membrane inclination, …

Neural Network Modelling Of Magnetic Effects In Solid-State Transformer Performance Under Variable Magnetic Operating Conditions, Godfrey Murairidzi Gotora, Blessed Ziyambe, Emanuel Rashayi

Engineering and Technology Journal

Solid State transformers (SSTs) are pivotal for renewable energy integration and smart grids, yet their performance is critically limited by non-linear magnetic effects such as core losses, flux- density saturation, and magnetising-inductance drift, that conventional analytical methods and prior artificial neural network (ANN) studies have struggled to model simultaneously across the electrical, thermal and magnetic domains. This study develops and evaluates a unified multi-output ANN framework that predicts six SST performance indicators which are efficiency, power density, total harmonic distortion, temperature rise, core loss and magnetising inductance from six operating variables (switching frequency, duty cycle, load current, ambient temperature, input …

Territorial Representation In Fiscal Governance: A Comparative Constitutional Analysis Of Indonesia's Regional Representative Council And South Africa's National Council Of Provinces, Endah Yuniningsih, Deden Rafi Syafiq Rabbani

Padjadjaran Jurnal Ilmu Hukum (Journal of Law)

This article examines the institutional role of territorial chambers in fiscal governance through a comparative constitutional analysis of Indonesia's Regional Representative Council (DPD) and South Africa's National Council of Provinces (NCOP). While the DPD was established to strengthen regional representation following Indonesia's decentralization reforms, its legislative role in fiscal policymaking remains institutionally constrained. Existing scholarship has primarily focused on the DPD's constitutional status in debates on bicameralism, with comparatively little attention to how constitutional design shapes the role of territorial chambers in fiscal governance and intergovernmental fiscal relations. Using a normative legal research method that combines statutory, conceptual, and comparative …

Geoengineering And Criminal Liability Comparative Lessons For Penal Reform, Zico Junius Fernando, Deviana Yuanitasari, Chairul Huda, Muhammad Yamani, Arimbi Fajari Furqon

Padjadjaran Jurnal Ilmu Hukum (Journal of Law)

Geoengineering has emerged as a controversial climate technology involving large-scale interventions such as cloud seeding, weather modification, and unregulated carbon capture. While these practices are promoted as solutions to climate change, they also generate significant ecological risks that remain largely unaddressed within criminal law frameworks. This article examines the absence of explicit criminal liability for geoengineering-related harms and explores how comparative legal experiences can inform future penal reform. This research uses normative research methods with several approaches, including comparative, conceptual, and futuristic approaches. The collected legal materials are analysed qualitatively, and content analysis is employed to classify and interpret relevant …

The Expansive Power Of The House Of Representatives As A Precondition For Constitutional Rot, Isnawati Isnawati, Adam Setiawan

Padjadjaran Jurnal Ilmu Hukum (Journal of Law)

This study examines how the expansive powers of the Indonesian House of Representatives have contributed to constitutional rot because those powers no longer operate effectively or proportionately. It identifies dysfunction in the House of Representatives through weak legislative performance, inadequate oversight of the executive branch, and transactional political practices in appointment processes. Using a doctrinal legal method and contemporary constitutional theory as its analytical framework, this study argues that the expansive powers of the House of Representatives constitute a precondition for constitutional rot, evidenced by the poor exercise of legislative authority and institutional intervention through amendments to the Rules of …

Reconstructing Legal Certainty In Legacy Oil Well Management: A Systemic Model For Resource Governance, Azhar Azhar, Bagaskara Sagita Wijaya, Siti Darwinda Mohamed Pero, Cynthia Azhara Putri

Padjadjaran Jurnal Ilmu Hukum (Journal of Law)

Legacy oil wells present persistent legal and institutional challenges in resource-dependent regions, where ageing infrastructure, informal extraction, environmental risk, and fragmented public authority intersect. This article examines how legal certainty is weakened in the management of legacy oil wells and how it may be reconstructed through a systemic model for resource governance. Using interdisciplinary socio-legal research, the study combines doctrinal legal analysis of Indonesia's oil and gas regulatory framework with qualitative field insights from Musi Banyuasin, a subnational setting in which formally recognised legacy wells coexist with community-operated wells. The analysis shows that legal uncertainty does not arise merely from …

Bank Indonesia's Floating Rate Notes (Bi-Frn) And Federal Reserve Instruments: A Comparative Analysis From An Institutional-Legal Perspective, Abdul Madjid Podungge

Padjadjaran Jurnal Ilmu Hukum (Journal of Law)

This paper analyses the legal validity of Bank Indonesia's Floating Rate Notes (BI-FRN) following the Law Number 4 of 2023 on the Development and Strengthening of the Financial Sector (P2SK Law) from a public law viewpoint. Doctrinal legal research utilises statutory, conceptual, and comparative methodologies, augmented by literature network visualisation, to pinpoint structural deficiencies. The network analysis reveals a significant divide between technical financial transactions and administrative legal oversight. The findings indicate that Article 11 of the P2SK Law enforces a stringent priority clause that centres monetary policy solely on Rupiah stability. This legal barrier prohibits abuse of power by …

How U.S. Legal Stagnation Can Be Aided By Decolonization, Marquel Gardner

McNair Summer Research Program

Decolonization is a term often used to present a simple shift from colonial thinking, heavily maintaining the establishment of colonial systems today. However, this usage oversimplifies and overshadows the word’s key purpose. Common proclamations of the term forgo the fundamental indigenous essence behind the word. Doing so, we not only strip the word of its inherent power, but obstruct further possibilities for actual decolonization to appear in our world. Many argue that the U.S. legal system, a product of colonial factors, has reached an alarming state. Our current legal, political atmosphere gears not towards justice or morality, but fascism and …

Tracking Toward Zero: Implementing A Picc Team Tracker To Prevent Clabsis, Christian Justin Carreon

Master's Projects and Capstones

Problem: Central line-associated bloodstream infections (CLABSIs) remain a significant and preventable patient safety concern in acute care settings, contributing to increased morbidity, mortality, prolonged hospitalization, and substantial healthcare costs.

Context: At Hospital A, a tertiary referral center in Northern California, six adult CLABSIs were identified between June and December 2025 following an eight-month CLABSI-free period. Four events occurred in adult medical surgical telemetry. All peripherally inserted central catheter (PICC) line CLABSIs were attributed to gaps in maintenance bundle adherence and the lack of a standardized, real-time tracking mechanism for the PICC Team.

Between Digital Transformation And Regulatory Vacuum: Cybersecurity Of Public Services In Mozambique, Faztudo Languisse Eng.

Journal of Cybersecurity Education, Research and Practice

The rapid expansion of digital public services in Mozambique—including e-government platforms, digital health systems, and electronic tax administration—has outpaced the development of a coherent legal framework for cybersecurity. While Law No. 3/2017 (Electronic Transactions Law) of 9 January 2017 introduced foundational data-protection principles, Mozambique long lacked a dedicated cybersecurity regulatory authority, mandatory security standards, and formal incident-notification mechanisms. This regulatory vacuum exposed critical public services to escalating cyber risks as digital transformation was actively promoted as a development priority. This article examines the legal and institutional gaps in Mozambique's cybersecurity governance framework prior to the 2026 Cybersecurity and Cybercrime Laws, …

Nutrition Labeling And Food Choice Behavior In A Cross-Border Context: Evidence From The Rio Grande Valley, Edith Galy

International Business and Entrepreneurship Faculty Publications

Unhealthy dietary habits have been linked to chronic conditions such as obesity, diabetes, and cardiovascular disease. As a result, governments have implemented nutritional labeling policies intended to assist consumers in making informed food choices. While the United States relies primarily on Nutrition Facts panels, Mexico recently adopted a front-of-package warning label system that uses highly visible warning symbols. This study examines how nutritional labels influence food choices among university students in the Rio Grande Valley, a unique border region where consumers are exposed to both U.S. and Mexican food-labeling systems. Data was collected through an online Qualtrics survey administered to …

Synodality In The Life And Mission Of The Lutheran Church-Missouri Synod, Ethan Engh

CSB and SJU Distinguished Thesis

This thesis provides a brief analysis of "synodality" and its roots in the Christian tradition, how that notion has been developed and applied during the Roman Catholic Church's "Synod on Synodality," and observes how the concept of "synodality" can be applied to the Lutheran Church-Missouri Synod (LCMS) by analyzing the structure and teachings of the LCMS and highlighting how the tenets of "synodality" harmonize with the LCMS.

Exposing And Addressing Machine Learning Brittleness Through Constraint Solving, Muyeed Ahmed

Dissertations

Machine Learning (ML) implementations are fundamentally brittle: nondeterministic, inconsistent, and prone to overfitting; however, constraint solving can be used to systematically expose, quantify, and address this brittleness.

This dissertation first establishes that widely-used implementations of popular ML algorithms are nondeterministic (producing different outputs on the same input, across different runs) and inconsistent (different implementations of the same algorithm producing different outputs on the same input). This is more prevalent in Unsupervised Learning (UL) implementations where, due to the lack of a ground truth, subtle execution errors can go unnoticed and are difficult to verify. Nondeterminism and inconsistency also introduce security …
