Metallurgical Investigation Of A Modified Eye Bolt Failure Caused By Improper Weld Extension, Specification Deviation, And Crevice Corrosion, Dimas Muhammad Fawwaz, Reza Miftahul Ulum, Johny Wahyuadi Soedarsono, Yudha Pratesa

Journal of Materials Exploration and Findings

A modified eye bolt from the David Arm Manhole Storage Tank underwent thorough metallurgical study due to the consequences of the bolt's malfunction during operation. Safety issues arose when the manhole door detached during operation. The mechanical testing and chemical composition analysis of the bolts indicated they were manufactured from an ASTM A193 Grade B7 material used for high-temperature bolting. This material did not conform to the engineering drawing, which mentioned SA 563A, which is about nuts, not bolts. This contradiction clearly shows that the eye bolt which was installed does not conform to the intended design. Welded connections of …

The Efficacy Of Transversus Abdominis Plane Block As An Adjunct To Spinal Anesthesia For Cesarean Delivery: An Evidence Synthesis And Implementation Toolkit, Alyssa Hebert, Alex Potts, Gabriela Robertson

Graduate Theses, Dissertations, and Capstones

Postoperative pain hinders cesarean delivery recovery and overall patient experience. Although spinal anesthesia with intrathecal opioids remains the standard of practice, associated side effects and concerns regarding opioid exposure highlight the need for effective opioid-sparing strategies. Anesthesia providers play a critical role in advancing postoperative pain management through evidence-based protocol development, provider education, and interdisciplinary collaboration to optimize maternal outcomes. The transversus abdominis plane (TAP) block provides somatic analgesia to the anterior abdominal wall by targeting the thoracolumbar nerves (T6–L1) and has increasingly been incorporated into multimodal postoperative pain management strategies for abdominal surgery. Nevertheless, a gap remains in obstetric …

Towards The Synthesis Of Dragonamide E And Analogs Thereof, Dante Glover

Chemistry Theses

Leishmaniasis is a disease caused by a parasite spread through the female sand fly. It is categorized as a Neglected Tropical Disease and can cause very severe symptoms, even death, if left untreated. Symptoms include skin lesions that can cause permanent scarring, and mucosal membrane infections that can cause facial deformities. More aggressive forms of leishmaniasis can lead to infections of internal organs like the liver and/or spleen and can lead to death. Drug resistance of these parasites has rendered treatment limited and the side effects of which can be harmful as well.

Scientists looking towards new treatments for tropical …

Persistent Chemotherapy-Induced Peripheral Neuropathy As A Chronic Cancer Pain Syndrome: Mechanisms, Therapeutic Limitations, And Future Directions, Reed Firestone, Jamin Morrison

Department of Medicine Faculty Papers

Background/Objectives: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, dose-limiting complication of cancer therapy and a major contributor to chronic neuropathic pain among cancer survivors. Although traditionally managed as a treatment-related toxicity, persistent CIPN frequently persists long after chemotherapy completion and is increasingly recognized as a major survivorship and palliative care challenge. This review synthesizes current mechanistic, clinical, and translational evidence and reframes persistent CIPN as a chronic neuropathic cancer pain syndrome. Methods: A narrative review of peer-reviewed literature was conducted using PubMed/MEDLINE, Embase, and the Cochrane Library, supplemented by manual review of key references and clinical guidelines. Emphasis was placed …

DePaul Discoveries

Two pyridinediimine (PDI) ligands were synthesized using green chemistry principles to minimize environmental impact and maintain synthetic efficiency. Previous syntheses require hazardous solvents and long reaction times. The reaction was carried out with a safer solvent, ethanol, and more rapidly using a CEM Discover microwave reactor. The PDI ligand was chosen for the scaffold for the aromatic core and support for different aniline derivatives. Comparative investigation of aniline electronics showed that 2,6-dimethylaniline was more successful than the electron-withdrawing electronics of 2,6-dichloroaniline. Synthesized complexes were characterized with proton nuclear magnetic resonance (NMR). The environmentally conscious microwave reaction produced effective and reproducible …

Department of Dermatology and Cutaneous Biology Faculty Papers

Langerhans cell histiocytosis (LCH) is a rare malignancy marked by clonal proliferation of Langerhans cells, with BRAF V600E mutations identified in over 50% of the cases. BRAF inhibitors (BRAFi), such as dabrafenib, have shown efficacy in treating BRAF V600E-mutant LCH. However, BRAFi therapy is associated with cutaneous adverse effects, including the development of new melanocytic nevi, verrucae, and keratinocyte carcinoma (KC). This case report describes a 78-year-old woman with BRAF V600E-mutant LCH who developed multiple dermatologic side effects following dabrafenib salvage therapy. Seven weeks into treatment, the patient presented with eruptive palmoplantar nevi, verrucae, and a basal cell carcinoma (BCC). …

Decoding The Allosteric Grammar Of Protein Kinases: A Dual-Stream Framework Integrating Protein Language Models And Energy Landscape Frustration Analysis, Will Gatlin, Max Ludwick, Lucas Turano, Brandon Foley, Kamila Riedlova, Vít Škrhák, Marian Novotný, David Hoksza, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The spatial and energetic encoding of allosteric regulatory sites remains a major challenge in structural biology, frequently representing a “blind spot” for sequence-based artificial intelligence (AI) models. We present a protein language model (PLM)-guided approach complemented by the energy landscape frustration analysis as a dual-stream framework to investigate the relationship between AI prediction of binding sites and biophysical organization of regulatory pockets across the human kinome. By probing a fine-tuned residue-level PLM classifier across 453 kinase structures, a clear performance gap is discovered between highly predictable orthosteric pockets (Types I, I.5, and II) and poorly resolved distal allosteric sites (Type …
