Abstract

This study examines current advances in the development of engineered photo reactor systems, photo catalysts, and process modeling and optimizations for photo oxidation procedures in water treatment. The impact of critical photo reactor operation parameters on photo-process performance with regard to disinfection and mineralization is investigated. For the first time, we show how to use a multi-variable optimization method to find the best operating parameters for a given process to improve photo oxidation efficiency. This study offers an overview of the many approaches used for treating oily effluents. The work focuses on photo catalytic degradation method and reflects published results in order to promote the approach as a viable and long-term process unit. At advanced oxidation processes, the possibility of the method in replacing a few identified degradation and separation techniques has also been indicated. [ABSTRACT FROM AUTHOR]

Abstract

This paper deals with the existence of a solution of a problem involving Leray–Lions type operators in Sobolev spaces with variable exponent. The proofs of our main results combine variational methods with energy estimates and Ekeland's variational principle. This paper improves and generalizes previous ones in literature, more precisely those of K. Kefi and V. Rãdulescu (Z. Angew. Math. Phys. 68, 80 (2017)) and M. M Boureanu (Discrete Contin. Dyn. Syst. Ser S, 12 (2) : 231-243 (2019)). [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we establish the existence of at least three weak solutions for the fourth-order problem with indefinite weights involving the Leray–Lions operator with nonstandard growth conditions. We generalize the result obtained by Kefi et al. [On the fourth-order Leray–Lions problem with indefinite weight and nonstandard growth conditions. Bull Math Sci. 2021;DOI:10.1142/S1664360721500089]. The proof of our main result uses variational methods and the critical theorem of Bonanno and Marano [On the structure of the critical set of nondifferentiable functions with a weak compactness condition. Appl Anal. 2010;89:1–10]. [ABSTRACT FROM AUTHOR]
