The presence of an inherited-centered singularity highlights the complex nature of black holes following gravitational collapse. However, non-linear electrodynamics (NLED) proposes the intriguing concept of a non-singularity, introducing new perspectives to this discussion. Our methodology explicitly incorporates NLED's role in determining the effective geometry of photons, advancing beyond standard metric analyses. The exact solution identifies a new correction term in the deflection angle that is specifically comparable to that of Reissner-Nordstrom (R.N.) model. These distinctive terms in the lensing effects significantly alter the sequence of shifts in the third angular images of a regular charged black hole. This analysis deepens our understanding of the complex interactions between a regular charged black hole and gravitational lensing. Future astronomical observations will be integral to corroborating these theoretically posited models, providing observational validation and potentially elucidating our theoretical framework.","PeriodicalId":14366,"journal":{"name":"International Journal of Science and Research Archive","volume":"2 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through qualitative thematic analysis, three key objectives were addressed: identifying benefits, examining implementation challenges, and assessing barriers to adoption. The analysis highlights significant benefits of blockchain adoption, including enhanced trust, transparency, automation, traceability, and data security, supported by findings from various studies. However, implementation challenges such as system design complexity, resistance to change, and inadequate IT staff pose obstacles to adoption. Furthermore, barriers to widespread adoption, such as the absence of a proper legal framework and the capital-intensive nature of blockchain adoption, were identified. These barriers underscore the need for collaborative efforts to address regulatory uncertainties and financial constraints. It was suggested that further studies could explore the long-term impacts of blockchain technology on supply chain resilience and sustainability, as well as investigate strategies to overcome implementation challenges and maximize the technology's potential across diverse industries and regions.","PeriodicalId":14366,"journal":{"name":"International Journal of Science and Research Archive","volume":"13 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, Omani literature postulates that Omani parents of children with ASD endure a higher parental burden, clinically significant stress levels, anxiety, depression, and an increased public stigma compared to parents of TD children. However, relatively little is known about parental stress constructs in the Omani literature. Research Design: A cross-sectional design was used to test a predictive model of parental stress in mothers raising children diagnosed with ASD in the Sultanate of Oman. Aims: This study examined mental health, parental burden, and affiliate stigma as predictors of parenting stress. It also examined the mediating role of self-compassion and the moderating role of coping strategies and social support between these potential predictors and parenting stress. Results: Results showed that affiliate stigma and parental burden were significant predictors of parenting stress. Self-compassion partially moderated the relationship between mental health, parental burden, and parenting stress.
