Abstract

A thorough evaluation examines the complex connection among fortification addition and Alumina Metal Matrix Composites' mechanical characteristics. Al MMCs' ability to improve aluminum-based materials' mechanical properties has made them a key field of materials research and engineering. When reinforced with ceramic particulate matter, fibers, or fur, Al MMCs improve in rigidity, strength, resilience to wear, and thermal stability. This review synthesizes and analyzes research to explain how reinforcement addition affects Al MMC mechanical properties. It also covers metallic powders, molten metalwork, and solid-state processes, each with pros and cons for structure and characteristic optimization. Silicon carbide (SiC), boron carbide (B4C), and carbon fibers are used to reinforce Al MMCs, and the review highlights their different effects on composite performance. Al MMCs play a crucial role in components that need outstanding mechanical qualities in the aviation, automotive, technology, and sporting goods industries, according to the assessment. The paper suggests optimizing reinforcement-matrix interactions, developing novel reinforcements with customized features, improving manufacturing methods, and exploring new application domains. This paper synthesizes current information and discusses future opportunities to advance and use Al MMCs in engineering. [ABSTRACT FROM AUTHOR]

Abstract

This paper reviews an innovative cooling system combining piezoelectric materials and nanofluids for high-performance computers. It explains the working principles of piezoelectric materials, detailing their context and construction, emphasizing the use of PZT lead zirconate titanate. The nanofluids, specifically Al2O3, enhance heat transfer efficiency. The construction of the piezoelectric micropump and methods for nanofluid preparation are outlined. The paper compares the advantages and drawbacks of nanofluids to traditional coolants, emphasizing stability challenges. It concludes by highlighting the potential of this integrated cooling system and suggesting areas for improvement. Overall, the proposed solution offers a promising avenue for enhancing electronic component cooling efficiency in compact systems. [ABSTRACT FROM AUTHOR]

5. PROSPECTS AND CHALLENGES IN URBAN TOURISM AND HERITAGE MANAGEMENT.

Subjects

Abstract

In many nations throughout the world, heritage tourism is becoming more and more well-liked. To revitalize industrial areas, change must be enabled and opposition to change must be overcome. In order to do this, the study looks at how urban tourism research has grown in connection to these paradoxes, including the results published in specialized journals on city tourism as well as the larger spectrum of results produced in social science. It also revisits the original claim made about an imbalance in the focus of urban tourism research, and how this has been addressed by a wider expansion of ideas at the nexus of urbanism and tourism. Diversifying tourism products at heritage sites like enhancing tourism marketing, visitor experiences, and infrastructures is fostering more inclusive, cooperative and integrated tourism and heritage management systems. Raising awareness of local resources while promoting eco-tourism and responsible travel and assisting local entrepreneurship and economic diversification are some of the strategies identified. In response to the unique requirements of the legacy business, the idea of heritage management has emerged. For the tourist business, heritage assets are priceless resources, thus conservation is an essential part of their management. Heritage sites need to emphasize their distinctive qualities, and the presentation of the attraction must be such that it can suit tourist demands while also fulfilling the management's obligation to the community to conserve the site for future generations.

Abstract

Background: Oesophageal cancer is the fourth most common cause of cancer-related deaths in India. Esophageal squamous cell carcinomas (ESCCs) arise from the epithelial layer, and commonly present as polypoidal, ulcerative or ulceroproliferative growth in the oesophageal lumen. In contrast, oesophageal submucosal tumours are a distinct group of tumours arising from the mesenchyme (examples include leiomyoma, fibrovasculoma, lipoma, granular cell tumour or carcinoid), and mostly do not breach the mucosa. Oesophageal submucosal tumours are a distinct group of tumours arising from the mesenchyme, and mostly do not breach the mucosa. Complete intramural growth of an advanced primary ESCC is an exceedingly rare presentation, with only six cases reported in the literature thus far. We herein report a case of primary ESCC with complete intramural invasion that endoscopically mimics a submucosal lesion., Case Summary: A 50 year old male presented with a progressive mechanical type of dysphagia for one month. His history was significant, including squamous cell carcinoma of the tongue that was treated with surgery and chemoradiation 1 year prior. Upper gastrointestinal endoscopy revealed a large, hemispherical lesion with normal-appearing overlying mucosa about 4 cm × 5 cm in size extending from 30-34 cm from incisors. The patient underwent endoscopic ultrasound (EUS), and a fine‑needle biopsy was performed, which was suggestive for squamous cell carcinoma. We herein report a case of primary ESCC with complete intramural invasion, endoscopically mimicking a submucosal lesion. The diagnosis could be established only by a EUS-guided biopsy., Conclusion: This case report highlights that intramural ESCC may look like a submucosal lesion in endoscopy, and EUS biopsy is needed for final diagnosis., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflict of interest., (©The Author(s) 2019.
