CONCLUSIONS Weak standard prevention is the main factor of SARS hospital aggregation epidemic. To realize standard prevention, education on standard prevention must be strengthened among medical staff from all level hospitals and health administration, sense and conduction of standard prevention must be promoted, devolopment and utilization of health device for treatment and prevention must be improved.
METHODS Based on bacteriological surveillance, the degree of pollution of device and its construction characteristics we adopted the local soaking method with 0.2% peracetic acid(PPA) and oxygen blowing to conduct disinfection.
A new molecular rectifier device and some research in its processing
The device with a sandwich structure shows good rectificative phenomena.
The highest rectification ratio 10000 was achieved in device Cu/MR-1/Ag, and about 100 in other device M/MR-X/M (M: Cu, Ag).
The electrospinning equipment was designed in a new way, wherein the spinneret was combined with a gas jet device.
In this review, we briefly summarize the current status of organic field-effect transistors including materials design, device physics, molecular electronics and the applications of carbon nanotubes in molecular electronics.
