Opis:: In Japan, the treatment of waste concrete scraps has been one of the environmental issues. Therefore, new application using pulsed power discharge has been developed as the recycling method of the coarse aggregates from the waste concrete scraps. In the work, the dependences of the quality of the recycled coarse aggregate by the repetitive pulsed discharge treatments on the consumption energy were investigated. As the results, it was clear that the quality of the recycled coarse aggregate could be controlled by the number of discharge treatments. The recycled coarse aggregate, which satisfied class H under the regulations of Japan Industrial Standard (JIS A5005 and JIS A5021), was produced with the smallest consumption energy when the discharged energy from 0.02 μF of capacitor charged up to 400 kV applied to the waste concrete scraps during single discharge treatment.

Opis:: Retrotransposons are mobile genetic elements that accomplish transposition via an RNA intermediate. These elements can be transcriptionally activated by stress factors, such as UV light, ozone, pathogens, wounding and drought. A red alga, Porphyra yezoensis has recently been recognized as a model plant for fundamental and applied study in marine biological science. In this paper, pulsed streamer-like discharge in liquid was used as a new stress condition, and the transcriptional levels of retrotransposon and functional genes of a red alga, Porphyra yezoensis was investigated. From the results of reverse transcription-polymerase chain reaction (RT-PCR) experiments, it is clear that the transcriptions of retrotransposon and functional genes were activated by applying pulsed streamer-like discharge.

Opis:: Recently, the pulsed power technology led us to generate discharge plasma in high-pressure gas, liquid and solid environment. The discharge plasmas have a lot of functions such as an intense electric field, a large current flow, a chemically active radical formation, a shockwave generation, and an ultraviolet irradiation. Using the functions, the pollution control technologies, including exhaust gases treatment, ozone generation, water treatment, and material destruction or separation, were developed in laboratory. In the paper, the NO removal by ns pulsed discharge plasma and the aggregate recycling by the discharge inside of concrete would be introduced.
