In this paper, the reactive yellow 14 dye solution was rem.ved from.aqueous solution in the presence of com.ercial ZnO (m.an crystallite size is 44.116 nm. under the UV A light. The decolourization of dye process was obeyed to pseudo-first orderkinetics. The optim.m.conditions of decolourization for this dye such as: initial dye concentration 50 m./L, best dose of ZnO 350 m./100m. and initial pH of aqueous solution of dye 6.75 were studied. Activation energies for dye were found to be 27.244 kJm.l-1. The photoreaction process was observed to be endotherm.c reaction and less random.ess.

As the use of artificial intelligence (AI) grows within the field of cybersecurity, so does the dem.nd for secure and decentralized AI system. to protect against potential cyber threats. Blockchain technology has em.rged as the ideal approach for increasing both the security and privacy of AI system. since it provides decentralized and im.utable data storage. This system.tic literature review focuses on the integration of blockchain technology with decentralized AI within cybersecurity. It provides a com.rehensive taxonom. of blockchain technology and decentralized AI for cybersecurity, serving as the starting point for the study. This paper begins with an overview of blockchain technology and its possible uses in cybersecurity and also analyzes its challenges and opportunities. Decentralized AI is also covered in the study, along with its potential advantages and difficulties in decentralized AI cybersecurity. Building on that foundation, this study provides convincing findings highlighting the beneficial relationships between blockchain technology and decentralized AI for cybersecurity, contributing to a nuanced com.rehension of their integration. m.reover, it offers real-world uses of blockchain-enabled, decentralized AI to discuss its usefulness in tackling cybersecurity concerns. Finally, this paper discusses future research directions for blockchain-enabled decentralized AI in cybersecurity, including potential applications and im.lications of this technology in the field, em.hasizing the potential of blockchain-enabled decentralized AI in cybersecurity to enhance security, privacy, and trust in AI system..

Objective: To develop and internally validate a nom.gram.to predict recurrence-free survival (RFS) including the tim. to radical cystectom. (RC) and perioperative blood transfusion (PBT) as potential ***: Patients who underwent open RC and ileal conduit between January 1996 to Decem.er 2016 were split into developing (n=948) and validating (n=237) cohorts. The tim. to radical cystectom. (TTC) was defined as the interval between the onset of sym.tom. and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nom.gram. Discrim.nation, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve ***: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On m.ltivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, pm.re units: HR 1.72, 95% CI 1.29-2.29, pm.us cell carcinom.

The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities.
