These techniques include the Laplace Adomian decomposition method (LADM), the Laplace variational iteration method (LVIM) and the reduced differential transform method (RDTM). The suggested approaches consider the use of the suitable initial conditions and find the solutions without any discretization or limiting traditions. Furthermore, their solutions are in the form of quickly convergent series with easily calculable terms. Numerical studies of four numerical applications are provided to certify the effectiveness and reliability of the suggested approaches, also to compare their computational effectiveness with each other and with other supplementary methods in the available literature. In addition to explore the properties of the solutions when changing the fractional derivative parameter. Numerical results demonstrate the effectiveness and accuracy of the suggested methods.","PeriodicalId":11368,"journal":{"name":"Delta Journal of Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79924972","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}

Due to its qualities including biocompatibility, biodegradability, mechanical strength, and processability, PLA has become a crucial polymeric material for biomedical applications. By fermenting sugars sourced from renewable resources like corn and sugarcane, lactic acid (LA) can be produced.
