The process of buying and selling via internet platforms is referred to as E-commerce. E-commerce has become a worldwide trend in recent years. People from all around the world have begun to purchase things online. Mobile commerce, money transfer, inventory management, and other aspects of electronic commerce are included. With only a few clicks, anyone can send anything to anyone, whether it's money or presents. In the future, electronic commerce might have a significant economic impact. Internet business will permanently alter the face of business. Furthermore, in the twenty-first century, E-commerce will transform banking. E-commerce has had a wide range of effects on the increasing global economy. First and foremost, it has impacted information technology and all economic sectors; above all, E-commerce has boosted global productivity growth and its impact are too high. They are able to determine the number of qualified people required to advance their country's information economy, as well as calculate the amount of investment required to provide businesses with internet access. Some benefits are now in a position to compare their economies to those of their international competitors, and there are numerous ways to boost productivity growth in present emerging markets.

A mechanistic approach to understand the course of metabolism for synthetic 1,2,4-trioxanes, potent antimalarial compounds, to evaluate their bioavailability for antimalarial action has been studied in the present work. It is an important parameter to study the course of metabolism of a drug candidate molecule when administered via oral route during its journey from oral intake to its target site. From the pharmacokinetics point of view, it determines the bioavailability of an active drug or a prodrug at the target point. In this work, synthetic arylvinyl-1,2,4-trioxanes 1a – u have been evaluated under various acidic conditions to mimic the milieu of the stomach (pH between 1.5 and 3.5) through which they have to pass when administered orally. The effect of acid on trioxanes led to their degradation into corresponding ketones and glyoxal. Under such acidic conditions glyoxal polymerized to form a nonisolable condensate product. The study indicates that the actual bioavailability of the drug is far less than the administered dose.

The merging of AI and CS has opened new possibilities for both disciplines [AI]. When used to the creation of intelligent models for malware categorization, intrusion detection, and threat intelligence sensing, deep learning is only one example of the many types of AI that have found a home in cyber security. The integrity of data used in AI models is vulnerable to corruption, which increases the risk of a cyberattack. Specialized cyber security defence and protection solutions are necessary to safeguard AI models from dangers such as adversarial machine learning [ML], keeping ML privacy, preserving federated learning, etc. These two tenets form the basis of our investigation into the effects of AI on network safety. In the first part of this essay, we take a high-level look at the present state of research into the use of AI in the prevention and mitigation of cyber-attacks, including both the use of more conventional machine learning techniques and existent deep learning solutions. We then examine possible AI countermeasures and divide them into distinct defence classes according to their characteristics. To wrap up, we expand on previous studies on the topic of building a safe AI system, paying special attention to the creation of encrypted neural networks and the actualization of secure federated deep learning.
