The current research work presented the synthesis of carboxymethyl cellulose–gelatin (CMC/GEL) blend and CMC/GEL/ZnO-Nps hydrogel films which were characterized by FT-IR and XRD, and applied to antibacterial and antioxidant activities for food preservation as well as for biomedical applications. ZnO-Nps were incorporated into the carboxymethyl cellulose (CMC) and gelatin (GEL) film-forming solution by solution casting followed by sonication. Homogenous mixing of ZnO-Nps with CMC/GEL blend improved thermal stability, mechanical properties, and moisture content of the neat CMC/GEL films. Further, a significant improvement was observed in the antibacterial activity and antioxidant properties of CMC/GEL/ZnO films against two food pathogens, Staphylococcus aureus and Escherichia coli. Overall, CMC/GEL/ZnO films are eco-friendly and can be applied in sustainable food packaging materials.
Environmental issues are most important among the current global concerns, and business activities are seen as a cause of significant threat to the environment due to environmentally non-friendly practices by various industries that cause pollution. However, the implementation of green supply chain management (GSCM) practices in developing countries like Pakistan is still inconclusive. The purpose of this paper is to investigate the impact of GSCM dimensions on economic, environmental, and social performance. The five dimensions covered in this research are green purchasing, green manufacturing and remanufacturing, environmental education, internal environmental management, and investment recovery. A survey questionnaire was prepared that consists of green practices as well as a performance indicator. Factor analysis maximum likelihood method was used to examine the survey data of Pakistani organizations. The results of this study indicate that GSCM practices have a positive impact on environmental, economic, and social performance. This research shows organizations are aware of improving their performance while adopting green supply chain practices.
In the competitive globalized market, risk management is an important aspect of the supply chain, but it becomes crucial to the management of a faith-based supply chain. The halal supply chain is an emerging research era at an early stage. To retain the halalness from procurement to end customer, this research was aimed to identify and prioritize the important risk elements for managing the HSC. For this purpose, a literature review was studied, 42 risk factors, classified into seven dimensions, were categorized with the expert’s opinion. A fuzzy best–worst method was proposed to analyze and prioritize the risk elements. The results indicated production-related risks are highly significant and sustainability-related risks are the least important among risk elements in the Halal supply chain. This research makes a major contribution by compiling a detailed list of risks associated with Halal supply chain management. It may also assist the manager in mitigations of risks for the Halal supply chain on a priority basis.
In game Industry, the most trending research area is shortest path finding. There are many video games are present who are facing the problem of path finding and there is various algorithms are present to solve this problem. In this paper brief introduction is given in the most using algorithm for path finding and A* algorithm has been proved the best algorithm for resolving the problem of shortest path finding in games. It provides the optimal solution for path finding as compare to other search algorithm. At the start of the paper, brief introduction about the path finding is given. Then the reviews of different search algorithm are presented on the basis of path finding. After that information of A* algorithm and optimization techniques are described. In the last, application and examples how the path finding techniques are used in the game is addressed and future work and conclusion are drawn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
