The geometric integrity of the fusion zone (FZ) is a critical determinant of weld quality in Tungsten Inert Gas (TIG) welding. This study presents a comparative analysis of Response Surface Methodology (RSM) and Artificial Neural Networks (ANN) for modeling and predicting FZ width geometry in AISI 1020 mild steel weldments. Experiments were conducted using a Central Composite Design (CCD) comprising 30 runs, varying current, voltage, travel speed, and gas flow rate. A quadratic regression model ...

The Old Man and the Sea, as Hemingway’s peak work, has been interpreted from the perspectives of heroism, symbolism or metaphorical interpretation, but Santiago’s “oldness” has been rarely studied even neglected. Under the framework of Age Studies, this thesis focuses on the “decline narrative” in this novella to reveal the triple decline: Santiago’s aging body, Hemingway’s waning writing talent, and Spain’s fading empire power. The intertwining decline narratives deconstruct the s...

Part-of-speech conversion is one of the core techniques in the translation of petroleum scientific and technical English. In the context of petroleum technical texts, English and Chinese differ remarkably in lexical structures, making literal word-for-word translation hardly feasible. Combining practical translation cases in the petroleum technical corpora (covering drilling, reservoir engineering, oil production, industry standards and field operation manuals), this paper systematically analyze...

Purpose: This systematic review aims to analyze the correlation between traditional clinical methods and cone-beam computed tomography (CBCT) in determining the periodontal biotype. Materials AND Methods: An electronic search was conducted to identify clinical observational and comparative studies comparing CBCT with conventional clinical techniques for assessing gingival and bone thickness. The study followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analys...

As a core concept in modern psychology and psychoanalysis, Freud’s theory of narcissism offers a crucial perspective for exploring the complex human mental structure and bears profound connections with the myth of Narcissus in literary contexts. Oscar Wilde’s classic novel The Picture of Dorian Gray is regarded as a modern reworking of the Narcissus tradition. Through the psychological alienation of its characters caught between aestheticism and extreme egocentrism, the work vividly revea...

Background: 3D-printed resins are increasingly used for temporary restorations in fixed prosthodontics, but their biocompatibility compared to conventional and CAD/CAM-milled resins remains insufficiently established. Objectives: To synthesize data on the biocompatibility of 3D-printed temporary resins compared to conventional and CAD/CAM-milled resins, and to identify post-processing parameters influencing this profile. Sources and Methods...
