This study investigates the optimization of process parameters for coating silk sutures with Acanthus ilicifoliusleaf extract. The increasing awareness of surgical site infections is a critical concern associated with the use of sutures in medical procedure undertaking. Our study aimed to assess the impact of three crucial coating factors, namely extract content, temperature, and duration, on the mechanical and antibacterial characteristics of silk sutures braided together. Through Box–Behnken design, in conjunction with the response surface approach, we conducted a thorough analysis to refine the model. The result showed that extract concentration directly influences both antimicrobial activity and elongation, while temperature and time primarily affect tensile strength and bending stiffness. To achieve the maximum tensile strength, minimum breaking elongation, minimum bending stiffness, and lower friction, all while maintaining the important antimicrobial efficacy of the sutures, this study emphasizes the use of response surface methodology in optimizing coating parameters for A. ilicifoliusleaf extract on silk sutures. The response models are developed on the complex relationships between these parameters and the properties of the sutures.

Due to the evolution of the Electronic Learning (E-Learning), one can easily get desired information on computer or mobile system connected through Internet. Currently E-Learning materials are easily accessible on the desktop computer system, but in future, most of the information shall also be available on small digital devices like Mobile, PDA, etc. Most of the E-Learning materials are paid and customer has to pay entire amount through credit/debit card system. Therefore, it is very important to study about the security of the credit/debit card numbers. The present paper is an attempt in this direction and a security technique is presented to secure the credit/debit card numbers supplied over the Internet to access the E-Learning materials or any kind of purchase through Internet. A well known method i.e. Data Cube Technique is used to design the security model of the credit/debit card system. The major objective of this paper is to design a practical electronic payment protocol which is the safest and most secured mode of transaction. This technique may reduce fake transactions which are above 20% at the global level.
