The Effects of E-scrap Supply Shocks on Recycling by the Non-Ferrous Metals Industry

Recently, Japan has been faced with the problem of scarce resource utilisation such as non-ferrous metals. Non-ferrous metals can be generated by the recycling of scrap materials; for example, used personal computers, used mobile phones, and used home appliances, which are commonly known as “E-waste (Electronic Waste)” or “E-scrap (Electronic Scrap).” Most E-scrap generated in Japan has been exported to Asian countries for the purpose of reuse. International reuse of E-scrap inversely prevents the scarce resources from circulating domestically in the country where the waste was generated. In short, we face a trade-off relationship between resource circulations domestically and internationally.In this study, we examine the implications of the simultaneous equilibrium in three related markets; domestic E-scrap, foreign E-scrap, and composite inputs. We use the method of “equilibrium displacement modelling” (EDM), so termed by Piggott (1992), which uses equations representing the demand and supply sides of each market. Based on this approach we can derive the elasticities that show the effects of supply shocks of domestic and foreign E-scrap on the related markets

Summary of the

The possible existence of deeply-bound $\bar K$-nuclear bound states, kaonic nuclei, has been widely discussed as products of the strongly attractive $\bar K$N interaction in I = 0 channels. Investigations of those exotic states will provide us unique information of the $\bar K$N interaction below the threshold, which is still not fully understood so far. Recently, we observed the simplest kaonic nuclei, $\bar K$NN, having a much deeper binding energy than normal nuclei via inflight (K−, N) reactions at the J-PARC E15 experiment. For further studies, we have proposed a series of experimental programs for the systematic investigation of light kaonic nuclei, from $\bar K$N (Λ(1405)) to $\bar K$NNNN. We will measure the $\bar K$NNN (A = 3) system at the new experiment approved as J-PARC E80, as a first step toward a comprehensive study

Measurement of KN scattering below the KN mass threshold

Abstract. We measured πE invariant mass spectra below and above the K¯N mass threshold in the K−d → NπE reaction in order to study the K¯N interaction and the Λ(1405) resonance. This reaction can be described by the two-step process: (i) K¯N1 → K¯N followed by (ii) K¯N2 → πΣ, where N1 and N2 are nucleons bound in the deuteron. We deduced the S -wave scattering amplitude of K¯N →K¯N in the framework of the K¯N πΣ coupled channel so as to reproduce the observed πΣ spectra in the I = 0 channel. We found a resonance pole at 1417.7-7.4+6.0 (fitting error)-1.0+1.1 (systematic error) - i[26.9-7.9+6.0 (fitting error)-2.0+1.7 (systematic error)]MeV/c2
