From Decay to Redemption: Exploring the Theological and Rhetorical Dimensions of C.A.W. Clark’s “The Worms Got Him”
Get PDFThe essay explores Reverend Caesar Arthur Ward Clark\u27s sermon, The Worms Got Him, as a remarkable representation of the black preaching tradition and a nuanced rhetorical masterpiece. Clark\u27s vivid description of the Herod family graveyard, intricately woven with historical and biblical references, engages the audience in a nearly physical and moral journey. Through deft use of honed rhetorical techniques, Clark immerses the listeners in a journey through history and the Herodian graveyard, allowing them to witness the Herodian dynasty\u27s moral decay personally
A computational fluid dynamics approach to analyze the virtual impactor in pneumatic aerosol jet printing
Get PDFAerosol jet printing (AJP) is a 3D printing, advanced manufacturing process that generates an aerosol mist appropriate for fine printing small, low-volume electronic parts. The pneumatic aerosol jet printing technology’s virtual impactor is the focus of this study. In this technology, high velocity nitrogen gas aerosolizes various inks in the atomizer. The aerosolized stream of ink is then transported to a virtual impactor (VI) to become dense and concentrated as it begins to enter the deposition head for high precision electronics printing. AJP faces challenges in large-scale adoption due to challenges related to overspray, instability, ink clogging etc. There is discrepancy in the knowledge of the sources that cause such issues. Computationally simulating the pneumatic aerosol jet printing environment provides insights into unapparent ink flow behavior that may contribute to printing inefficiencies in the system. While the pneumatic atomizer and deposition head are sufficiently simulated and analyzed, the VI lacks the same focus. Therefore, simulating the VI environment provides a comprehensive understanding of the pneumatic AJP technology.
This is accomplished by 3D computational fluid dynamics (CFD) modeling and simulation of the VI system in ANSYS Fluent. First, an initial characterization of the system is completed by creating a 3D CAD model based on x-ray images of the VI by Optomec and a subsequent CFD analysis using a turbulent k-epsilon model. Second, design investigations and corresponding CFD simulations are conducted by altering critical design parameters in the system such as the impactor and collector lengths, impactor to collector diameter ratio, and aerodynamic transport channels (ATC) count and diameter. The initial characterization study revealed that the VI experiences nonuniform flow removal, flow circulation, and increased EGF port velocity
Big data analytics in inventory management in healthcare supply chain
Get PDFIntroduction: As healthcare organizations increasingly have relied on digital transformation to meet growing demands for efficiency and cost reduction, big data analytics have emerged as a key tool for optimizing supply chain performance. Inventory management, which accounted for up to 50% of total hospital operating costs, remained one of the most critical and complex areas in the healthcare supply chain. Traditional inventory methods often led to stockouts, waste, and inefficiencies. The integration of big data tools such as predictive analytics and enterprise resource planning systems presented an opportunity to streamline operations and reduce costs.
Purpose of the Study: The purpose of this study was to evaluate the impact of implementing big data analytics compared to traditional inventory management methods on inventory efficiency in healthcare, focusing specifically on decreased stockout rates, reduced inventory waste, and lower supply chain costs.
Methodology: This study utilized a qualitative literature review combined with a semi-structured interview. Twenty-three peer-reviewed articles published between 2017 and 2024 were analyzed, and one expert interview with a healthcare supply chain manager was conducted to support the literature findings with real-world experience. Data was gathered using PRISMA guidelines and included U.S.-based sources from academic databases and professional associations.
Results: One study showed that the use of big data analytics significantly improved inventory efficiency. Key metrics included a reduction in stockouts by up to 20%, a 30% reduction in inventory levels through Vendor-Managed Inventory systems, and cost savings of up to 25% annually. The interview highlighted the advantages of ERP systems like Infor in enabling better access to data, improving staff efficiency through handheld use, and enhancing forecasting. However, challenges such as inconsistent lead times, labor force education, and underutilization of technology were also identified.
Discussion/Conclusion: Big data analytics improved inventory tracking, forecasting, and cost management in healthcare settings. However, implementation success was heavily dependent on capital investment, workforce training, and organizational readiness. The findings were largely positive but not universally conclusive due to ongoing operational barriers. Further research was recommended to evaluate the long-term impact of analytics integration and to address persistent challenges in healthcare supply chain management
Atypical presentation of Non-Small Cell Lung Carcinoma with metastasis to breast tissue
Get PDFMalignant neoplasms of the lung commonly metastasize to lymph nodes, bone, brain, and liver via hematogenous and lymphatic routes. Much less commonly, metastasis occurs in the breast. Secondary metastatic disease of the breast is very rare, with a reported incidence ranging from 0.4-1.3%—with primary lung cancer being one of the most anomalous sources. This case details non-small cell lung cancer metastasis to the breast with proven primary contralateral lung origination. This atypical finding prompts medical professionals to consider these malignant cells\u27 immunologic, histologic, and pathologic makeup to understand further and treat the neoplasm
Successful flexible bronchoscopic extraction of a dental foreign body aspirated into the left mainstem bronchus
Get PDFForeign body aspiration (FBA) is a potentially life-threatening emergency that commonly occurs in children but varies widely in clinical presentation. Rapid diagnosis and intervention are of the utmost importance to prevent complications such as airway obstruction, infection, and lung injury. While uncommon in adults, most encountered causes occur in the setting of intoxication, neuromuscular weakness, or iatrogenic dental work. Those with dental prostheses are especially susceptible due to the partially attached nature, rendering the risk of accidental dislodgement. This report discusses an uncommon case wherein an 82-year-old male aspirated a dental bridge into his left mainstem bronchus during routine dental treatment. Flexible bronchoscopy with a urology basket had to be employed for successful removal. The choice of extraction technique via flexible or rigid bronchoscopy largely depends on the specific features and location of the foreign body; however, there is much debate about whether specific criteria warrant one over the other or if flexible should always be the first line. Preventive measures, including rubber dams, should be utilized to minimize the risk of aspiration during dental procedures, as the downstream effects can be deleterious. Despite the uncommon clinical occurrence of an adult aspirating a dental foreign body, this case report emphasizes the clinical importance of primary prevention to avoid similar occurrences
Participant 009: Reiki Practitioner with one year of experience (Latin American; Female; England, United Kingdom)
Get PDFThis is an interview about Reiki and its connection with overall well-being with a Reiki Practitioner holding ~one year of Reiki experience (Latin American; Female; England, United Kingdom).
