An innovative in-flight glass melting technology with induced thermal plasmas was developed for the purpose of energy conservation and environmental protection. Two-dimensional modeling was used to simulate the thermofluid fields in the plasma torch. The in-flight melting behavior of glass raw material was investigated by various analysis methods. Results showed that the plasma temperature was up to 10000 K with a maximum velocity over 30 m/s, which made it possible to melt the granulated glass raw material within milliseconds. The carbonates in the raw material decomposed completely and the compounds in the raw material attainted 100% vitrification during the in-flight time from the nozzle exit to substrate. The particle melting process is similar to the unreacted-core shrinking model.

In this study the sub-tidal and intra-tidal variations of salt fluxes in the upstream section of a shallow estuary （with a water depth of less than 3 m） were investigated. The salt fluxes were estimated based on the cross-sectional average salinity and velocity measured by the fluvial acoustic tomography system （FATS）. The results indicate that the magnitude of seaward fluxes is approximately two times greater than that of landward fluxes under normal conditions. The results of short-term observation in the study area indicate that there is a phase lag of the bottom and surface salinities between the regions with the largest and smallest depths. The vertical shear flux with a peak value of-0.7 m2/s during the ebb tide indicated an important contribution to the total salt flux compared with the advective flux. A phase lag occurred between the vertical shear terms in the regions with the largest and smallest depths, which resulted from the correlation between the vertical variations of the salinity and velocity and the existence of transversal velocity circulations.

A novel method has been established to realize the experiment of electron scattering off short-lived nuclei. The method was based on the well known ＂ion trapping＂ phenomenon in electron storage rings. In the R^D experiments at Kyoto University, stable nucleus, 133^Cs, was employed as the target nucleus. The luminosity of scattering experiment was nearly 1026 cm^-2s^-1 at electron beam current around 75 mA. The angular distribution of elastically scattered electrons from trapped Cs ions was measured and the result was well fitted by theoretical calculation. It was indicated that higher luminosity can be reached with larger electron beam current.

Dear Editor,Intensive treatments such as primary androgen deprivation therapy(pADT)plus docetaxel or abiraterone acetate are reportedly beneficial in metastatic prostate cancer(mPCa)patients with high-volume disease or high-risk features,respectively.1,2 High-volume or high-risk features are determined exclusively via pretreatment *** patient responsiveness to pADT,which is one of the major determinants of survival in these patients,would be advantageous with regard to making primary treatment *** an initial 3-month period is possible,short-term serum parameter dynamics can be used to predict pADT ***-specific antigen(PSA)and alkaline phosphatase(ALP)dynamics have been indicated as potential predictors.3,4 Although pADT can reportedly cause a 20%-30%decrease in adrenal androgen levels,5 it is not known whether the dynamics of adrenal androgens shortly after the initiation of pADT can predict pADT *** aim of the current study was to identify predictors of pADT responsiveness among pretreatment parameters and 3-month dynamics(D3m)of serum parameters including the adrenal androgen,dehydroepiandrosterone sulfate(DHEAS).
