India had broken all the records and counts of confirmed COVID-19 cases per day and daily death toll reached over thousands. India is way far from other developed nations in the number of vaccine doses per 100 population. Although vaccination is an effective measure to be followed to overcome this grave situation, still certain misconceptions and rumors throughout the country have pulled a decent part of the population from being vaccinated. Another big challenge is production and supply of vaccines to meet the demand. COVID-19 pandemic will not end until the entire population gets vaccinated that would protect them from this deadly disease. Therefore, this paper aims at clearly identifying the factors and subsequently prioritizing them as barriers in effective immunization against COVID-19 in India following multi-criteria decision making (MCDM) technique. In this study, a fuzzy decision-making trail and evaluation laboratory (F-DEMATEL) approach is applied for understanding the contextual relationship among the barriers for effective immunization against COVID-19. The methodology is followed in a fuzzy environment to address the issue of uncertainty in the data gathered. The result suggests that the ‘Misinformation/ Misconceptions/ Lack of vaccine education in underserved communities’, ‘Lack of information regarding a vaccination center close to home’, ‘Difficulties in getting appointments’, ‘Supply chain issues in the distribution of vaccine’, and ‘Lack of access for marginalized communities’ are the important barriers in effective immunization against COVID-19. Recommendations have been made to overcome this situation and help to immunize the population and drag COVID-19 down to earth.

The significance of producing Carbon nanomaterials (CNMs) reinforced polymer composites are increasing in manufacturing trades due to their exceptional performances. CNM modified composites are primarily employed in structural component needs due to expanded physicomechanical properties. This paper highlights a coherent approach of the VIšekriterijumsko KOmpromisno Rangiranje(VIKOR) and Teaching learning-based optimization algorithm (TLBO) to evaluatethe Milling efficiency. The machining was performed for the Milling process of0-D carbon nano onion (CNO) reinforced polymer (Epoxy) composite at four different levels of Box Behnken Design (BBD). The Milling performances such as Material Removal Rate (MRR) and Surface roughness (SR) were optimized to enhance product quality and productivity. The control of varying process constraints, viz. Weight % of CNO filler content(A), cutting speed (B), feed rate (C) and depth of cut (D), was used to optimize the machining response. The conflicting response is aggregated through the VIKOR method to develop the fitness function for an algorithm. The process constraints play a significant role in influencing the cost and productivity ofthe machined components. The objective function derived from VIKOR was supplied as input into the TLBO algorithm. The results demonstrated that the spindlespeed, feed rate, and weight % of CNO filler are the most contributing factors for machining indices. Also, the hybrid VIKOR-TLBO module shows a lower error percentage than the conventional VIKOR method. The microstructural investigation of the machined surface reveals the feasibility of the proposed hybrid module in a production environment.

The term dissolution of the company refers to the expiration of the legal relationship between the partners, in different words the dissolution of the moral character of the company. Basically, commercial companies are established for the purpose of achieving the objective and the profits which are impossible for each partner to achieve alone, so partners work hardly to keep this company standing and ongoing practicing its commercial activities.in this paper focuses on the most prominent reasons for the expiry of commercial companies, whether partnerships or corporations, whether by the expiration of the definite-period of the company on the Saudi System for Companies. Also each company represents a person with a moral character who is entitled to legal capacity which enables it to acquire the rights and bear the liabilities the same as the natural person. The company is entitled to practice its activities with the assigned purposes of establishment and to conclude all legal acts including selling, purchasing, renting, leasing and whatsoever. Gaining the moral character capacity makes the company entitled to be plaintiff or defendant in case of disputes with other parties. Thus, in this scientific paper shall discuss the independent reasons which are entitled by the companies in its capacity as moral persons, moreover it can go beyond to other factors as well as being dependent by liability against other companies liabilities, and having a deputy to represent this company. It is also entitled to have the nationality of the country where its management office is located.

Welding is widely used in all industries, and its demand is drastically increasing. Today, all sectors of engineering need quality welders to meet their standards. Welders need years of experience and knowledge to meet those standards. They require lots of training, equipment, tools, and safety standards to master the welding skill. The cost of training is very expensive as they will be practicing every day with different materials. The purpose of this project is to train them in a new merged-up environment of the virtual and real world. As a result, this method would reduce training costs and enhance the safety of the users. This method is a medium that helps users to have a better understanding of welding operations and gives them the confidence to perform proficiently in reality along with the elimination of risk, liability, and injury.

Electricity systems are currently expanding towards more efficient forms of production. Several expansionary strategies are being developed to cover increases in future electricity demand. Goals such as reducing greenhouse gas emissions, increasing the efficiency of operations, and achieving more equitable participation of the actors in charge of the investments are set. Following this premise, this paper presents a multi-objective model that helps in decision-making on the problem of expanding electricity generation. The model considers more realistic views than other works in the literature. The vast majority of the stakeholders in the studied field are satisfied with the present proposal. Investment costs, greenhouse emissions, and investment contribution rates are considered. Also, the actual procedures of the generation and transmission stages are rigorously studied. This means obtaining solutions that are closer to reality. The case study is the electricity system of Argentina. The results obtained indicate that the recommended solutions are the most convenient from all points of view. They constitute a mix of the generation with renewable and non-renewable technologies. The case study reveals emission reductions of up to 25% and it can be achieved that the most vulnerable social groups do not have to finance future system expansions.

This study focuses on developing a nano zinc oxide (ZnO) catalyst with fly ash (FA) as a support material for converting kapok seed oil (KSO) into biodiesel. This research aims to study the preparation of nano ZnO/FA solid catalysts and the catalyst's reactivity towards kapok seed oil biodiesel (KSOB) products. The catalysts were synthesized using a modification of the Stober process, which is the co-precipitation, impregnation, and precipitation step co-occurred. The catalyst is prepared on base condition using sodium hydroxide with a solvent of methanol and zinc chloride as a raw material. FA waste was effectively modified with zinc oxide particles to create a high-performance ZnO/FA composite catalyst. Under optimal stoichiometric NaOH and 60% ZnO, the resulting material achieved a remarkable specific surface area of 14.8 m²/gram, indicating its potential for enhanced catalytic activity. The prepared catalyst of nano ZnO/FA achieved successful methanolysis of KSO, with a maximum FAME yield of 61.09% attained at 65°C after 5 hours of reaction time, using a 3% catalyst dose and a KSO: methanol molar ratio of 1:15. The initial success of nano ZnO/FA with kapok seed oil paves the way for further development towards robust catalysts specifically tailored for low-grade oil conversion.
