Is the Travel Bubble under COVID-19 a Feasible Idea or Not?

The present study aimed to understand Taiwanese people's willingness to participate in the travel bubble policy. A mixed research method was used to collect 560 questionnaires, and SPSS 22.0 software was used for the statistical validation and Pearson's performance correlation analysis.

An Analysis of Exhaust Emission of the Internal Combustion Engine Treated by the Non-Thermal Plasma.

Industries' air pollution causes serious challenges to modern society, among them exhaust gases from internal combustion engines, which are currently one of the main sources. This study proposes a non-thermal plasma (NTP) system for placement in the exhaust system of internal combustion engines to reduce the toxic contaminants (HC, CO, and NO) of exhaust gases. This NTP system generates a high-voltage discharge that not only responds to the ion chemical reaction to eliminate NO and CO, but that also generates a combustion reaction at the local high temperature of plasma to reduce HC.
