The addition of nano/micro silica into unsaturated polyester resin (UPR) results in the improvement of the electricalproperties of Silica-UPR composites. The surface, volume resistivity, dielectric strength, dissipation factor and dry arcresistivity of nano silica-UPR composites were found to improve significantly. The effects of the nano and micro fillersin UPR have been evaluated. They are presented in this paper. To evaluate the electrical properties of the nano µ composites, all the measurements were done as per the prescribed methods in ASTM. It was observed that theaddition of nano silica improves the electrical properties as compared to micro silica. The better dispersion of silicaparticles in unsaturated polyester resin enhances the electrical properties of silica-UPR composites
Considering the properties of the carbon nano tubes (CNT), their inclusion into the polymer matrix vastly increasesthe properties of the resultant composite. However, this is not the case due to the poor interfacial adhesion of the CNTand the polymer matrix. The present approach focuses on increasing the interaction between the polymer matrix andthe CNT through the chemical modification of the CNT resulting in allyl ester functionalized carbon nanotubes (ACNT)and silane functionalized carbon nano tubes (SCNT) which are capable of reacting with the polymer matrix duringthe curing reaction. The addition of ACNT/SCNT into unsaturated polyester resin (UPR) resulted in the improvementof the electrical properties of resulted nanocomposites in comparison to the CNT. The surface resistivity, volumeresistivity, dielectric strength, dry arc resistivity, and the comparative tracking index of the nanocomposites weresignificantly improved in comparison to CNT. The chemical modification of CNT was confirmed via spectroscopy
Storage of data and using that data in an effective manner are the major issues in the health management system. Security of health data and the use of this data in a proper way are very important. This project of Health Record Management System is a web application-based project designed for the hospital to manage and use the data of their patients effectively. The main aspect of the project is to provide a system where the data can be stored and retrieved easily. The web application is designed from the scratch without any idea involving the existing systems. The project focuses on developing a simple system where the doctor can upload the data of the patient in the system and can retrieve it when needed. The patient can view the same data from their end. Moreover, the patients can book the appointment with the doctor through the application. The final project consists of a website which attains all the features of a management system. Another focus of the project is to develop a web-based application with application rich UI and UX interfaces which is very accessible even for the new users of the technology. The system is also notable for its great user friendliness.
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.
