Over 60 per cent of pupils in the COVID 19 epidemic created significant disruption in the educational system, and educational institutions across the globe were closed. Essential elements of e-learning during COVID-19 have been technology management, management support, improved student knowledge about the usage of e-learning systems and the need for a high standard of information technology from instructors, students, and institutions. This article aims to find key success elements for E-learning during COVID-19 by utilising the MSP and TOPSIS methods to improve the educational process. The objective of the paper was to identify crucial success factors for e-learning during COVID-19. In COVID-19, 69 E-learning managers were interviewed based on specified evaluation and e-learning methods across various channels. Mixed learning was the best appropriate training method for practical use among the five learning systems. These findings showed the readiness of E-learning to carry out instruction throughout the COVID-19 epidemic, regardless of how exceptional the technology was at a school.

Mobile ad hoc networks (MANETs) are perfect for positions here lacking preset structure. Nowadays, may experience from partitioning network. This restriction builds MANETs incompatible for applications for example, crisis management and battleground communications. To deal with this weakness, an Autonomous Mobile Mesh Network (AMMNET) is used. AMMNET introduce a disseminated tracking the client clarification to handle with the active nature of client movement, and this approach for dynamic topology alteration in accordance with the movement sample of the clients. However, the significant problems in AMMNET are to utilize an energy-efficient routing approach to extend the network lifetime. This approach introduced Ant Based Routing Algorithm for balanced the load and Optimized the AMNET lifetime (ARAB). It utilizes a well-organized heuristic update technique to optimize the path concern. This algorithm using pheromone trail revises to balance the utilization of energy. As a result, minimize the energy utilization induced with the control overhead. This approach balances the energy between clusters and evades preliminary network partitioning. Our simulation outcomes specify that ARAB is healthy against partitioning and accomplished of offering high forwarder throughput for the mobile clients.

The development of communication technologies shows that fiber optics is in the main communication improvement in the last decade. Fiber optics is moved from laboratory to be a reality. Transmission of the data using the light as a signal carrier is a revolutionary improvement in the communication era. However, to enable this technology several obstacles should be addressed, such as achieving the longest distance transmission with less possible bit error rate (BER). One of the solutions was performed by careful selection of the optical modes profiles with the help of the nonlinear electrical equalizer (NLEE) to solve the problem of the mode coupling. This paper investigates on the compensation of different modes profiles in optical communication systems over few-mode fiber (FMF) based on Space Division Multiplexer (SDM) with an electrical non-linear equalizer utilized to equalize nonlinear distortions. The result shows that the LG mode achieved the best transmission distance comparing to the other modes which make it the best option to be used. Basically, the evaluation of the system has been done based on standard evaluation metrics such as BER and Eye Diagram. These results can optimize the data transmission quality.

It is fairly obvious that we live in a toxic world and our brains are poisoned continuously, and this constant low level of exposure over time is slowly damaging our neurons and brain cells. The worse news is that this harmful toxic environment is not going to stop anytime in the foreseeable future and environmental toxins are a leading cause of neurological illnesses. It is also well established that oxidative stress contributes to various diseases including diabetes, heart disease, inflammatory conditions, high blood pressure, and neurological diseases such as Alzheimer’s and Parkinson’s. It is therefore inevitable that exposure to such conditions including heavy metals, EMF radiation, bacteria and viruses will require a strong immune system to defeat such harmful toxins, and that almost 80 percent of the immune system is located in the gut. The main causes of neurological diseases are already known and the standard drug treatments (e.g., Aricept and Namenda for Alzheimer’s) slow the progression of such terrible diseases, but they do not address the root cause of memory loss. Glutathione is known as body’s master antioxidant being effective against oxidative stress and inflammation. Along with other natural antioxidants in the body, it works to defeat the harmful effects of free radicals which cause damage to cells and tissue leading to various health conditions. In this review, the main factors, including environmental toxins, causing neurological illnesses like Alzheimer’s and Parkinson’s, and natural ways of prevention and treatment protocols have been discussed. The proposed treatment protocol could be lifesaving and is supported by the extensively published literature.
