The vision of Industry 4.0 is an integrated ecosystem in supply chain where every item and human in the plant has an ID in production and works without any external intervention, communicating with each other in every operation. Although such a concept of manufacturing may sound futuristic to many companies, and especially SMEs, the transition to this future is inevitable, and organizations need a roadmap to clearly understand the concepts and effectively execute the applications of Industry 4.0. In this paper, the level of importance of each Industry 4.0 criterion for SMEs is expressed and used to develop a quantitative maturity model. Analytic Hierarchy Process was utilized to calculate the weights of dimensions and maturity items. An iterative procedure led to 9 different dimensions and 33 correlated items. Initial findings showed that the "Strategy and Organization" dimension has the highest impact on maturity level along with the items "Manufacturing Software", "Employees", and "Industry 4.0 Roadmap".
This study was intended to evaluate the behavior of permethrin-containing capsules. To do this, permethrin was encapsulated in an ethyl cellulose shell via a simple coacervation method and microcapsule optimization analyses were conducted. Scanning electron microscopy analysis showed that the microcapsules were spherical and smooth. The microcapsules had a slender-sized distribution, and the average particle size was 50 μm according to laser diffraction analysis. Upholstery fabrics were treated with permethrin capsules via impregnation, printing, or coating to compare application methods. After application, the insecticidal effects of the pre-washed and post-washed fabrics were investigated. Insecticidal activity was evaluated against common house mosquitoes (Culex pipiens) using the World Health Organization’s cone bioassay. The mosquitoes tended to stay away from the treated fabrics, and mortality rates on the printed, coated, and impregnated fabrics were 52 %, 51 %, and 50 %, respectively. The fabrics still repelled the mosquitoes after five washes. This study demonstrated that microcapsules can be transferred onto fabrics by coating and printing methods in addition to the conventional impregnation process, and that treated upholstery fabrics can be used commercially to protect against mosquito-borne illnesses.
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.
