Today's growing population and the increasing global pandemics have made inroads for new technologies and developments for effective treatments and bringing in holistic health for scores of patients affected. Nanotechnology and nanomedicine are emerging technologies wherein the use of nanomaterials for drug deliveries has replaced the conventional systems of drug delivery, which are generally associated with side effects. Cancer nanotherapeutics has made skewed progress, bringing in a sea change in the delivery mechanisms whereby the problems of nonspecific biodistribution and targeting are being decimated to no-problem deliveries. The synthesis of smart nanoparticles has brought much hope and resilience to scores of patients needing the applications of tissue engineering and regenerative medicine. The smart drug delivery systems based on pH and temperature, magnetic, redox, and enzyme responsiveness have shown excellent therapeutic applications in autoimmune diseases and metabolic disorders. Tissue engineering is a field that has brought in new technologies in the medical world that improve, repair, and replace damaged tissue or organs. The applications of smart nanomaterials have envisaged new methods and developments in end applications like biomimetics. This review gives an overview of nanomaterial synthesis, smart drug delivery systems and their applications using nanomaterials, the role of nanomaterials in nanomedicine and tissue engineering, and finally, the significance of amalgamations of Theragnostics nanomedicine with nanoscience, therapeutics, and diagnostics.

The advancements in network technology and associated services have increased the volume of data traffic. However, the harmful impact caused by intruders has also increased. Intrusion activities can be addressed by utilizing Network Intrusion Prevention Systems (NIPS). NIPS can detect attacks by either comparing the traffic with predefined patterns or identifying deviations from normal traffic behavior. In this paper, the machine learning algorithms will be used to enhance the performance of the NIPS systems. First, feature selection algorithms will be used to remove irrelevant features from the network traffic data. In particular, the widely used Dragonfly Algorithm (DA) will be used for feature selection. Then, the Gradient-Boosted Trees (GBT) and Logistic Regression (LR) will be used to find the attack data based on the features selected by the DA algorithm. The UNSWNB15 dataset was used to assess the proposed NIPS system. The accuracy of GBT and LR reaches 100 % and 99.93 %, respectively.

Tourism is one of the most important economic activities in the Sultanate of Oman, as it has contributed to the development of the national economy, providing job opportunities and improving the standard of living for citizens. Strategic planning plays an important role in achieving tourism environmental development, as it provides a framework for setting goals and developing the necessary plans and programs to achieve these goals. Strategic planning for tourism environmental development is one of the most important tools that can be used to achieve sustainable development in the tourism sector in the Sultanate of Oman.

Massive Open Online Courses (MOOC) platforms play a vital role nowadays in knowledge creation and enhancement.Though, initially these programs and courses were offered freely, now due to emergence of technology and requirement, they were offered in both free and paid mode.Currently, the MOOCs provide various programs and courses that are administered by various international higher education institutions and private organizations.Moreover, the COVID -19 has triggered all the universities, colleges and institutions to move towards MOOC platforms as an online learning method.The students used these MOOC platforms to gain and enhance required knowledge in this competitive world.Due to this emergence, various research studies were conducted during the past years using different research methodologies and scopes to identify the usage, gaps, trends, advantages, disadvantages and user satisfactions.This paper reviews some major researches since 2010 and summarizes the findings to support future research scopes.The 16 research articles that were having more than 100 Google citation counts were considered for this study and analyzed.Currently, the number of students joining and completing the courses through online is significantly increased which showed that the learners' intention on getting the knowledge in the area of specialization has increased.Moreover, the acceptance and recognition of online courses and programs by various employers and institutions have been increase which opens a great opportunities for continuous and life-long learnings.Though, the completion rates of courses and programs thorough online platforms are increased comparatively now-a-days, the success rates, knowledge acquisition rates, actual participation rates and learning outcome attainment rates need to be studied in depth.

Omanization is a strategy applied by the Sultanate of Oman since 1988 with an aim to replace expatriate workers with Omani nationals. The Omani government has set goals to increase the percentage of employed Omani nationals compared with foreigners (expatriates) through Omanization as a routine Human Resource (HR) practice. This strategy was introduced because of the increasing number of expatriates that indirectly resulted in reduced job opportunities for Omani nationals. It is expected that this strategy would allow Omani nationals to get jobs and consequently needed training and development programs. This research work is focusing on Omanization and its likely impact on HR practices in Oman. As it was not feasible to collect data from both the public and private sectors, this research, therefore, aims to analyze the perceptions of private sector employees on Omanization. This research is expected to highlight likely changes in the HR practices applied and their effectiveness in Oman. It will be worthwhile identifying how employees from the private sector foresee this strategy, and whether the Omanization initiative can actually improve the quality of work and enhance HR output to reach a higher level of productivity. It is assumed that Omanization could have a significant impact on HR practices, so it was decided to conduct interviews and focus group discussions with some of the private sector employees to gain a richer insight. Findings from this research indicate that there is a gap between the labor market and the education system. It is evident that fresh graduates lack the necessary skills and training for taking over the positions. Furthermore, there is a lack of training and development programs for the employees. This research is highlighting some recommendations too for the progress toward Omanization.

Recently, complementary perfect corona domination in graphs was introduced. A dominating set S of a graph G is said to be a complementary perfect corona dominating set (CPCD – set) if each vertex in is either a pendent vertex or a support vertex and has a perfect matching. The minimum cardinality of a complementary perfect corona dominating set is called the complementary perfect corona domination number and is denoted by . In this paper, our parameter hasbeen discussed for power graphs of path and cycle.

A sequence of large scale direct shear tests were carried out to evaluate the involvement of passive bearing resistance at the interface of the cohesion less soil-geogrid in shear mode.Soil samples used are with varying proportions of Sand, 6mm aggregates and 12mm aggregates at different densities. The study results revealed that the transverse ribs contribute 17% of the total interface resistance for soil samples tested with the geogrid. From the test results it is observed that the shear strength at sandgeogrid interface mobilized under direct shear mode is depending on the density, size of the particles and thickness of ribs. Moreover, it is observed that the 21 % of passive resistance contributed by transverse ribs with respect to the total shear resistance found decreasing with increase of normal load at constant density and the passive resistance found decreasing with decreasing of density.
