Meth.l meth.crylate (MMA) was grafted onto silk fiber in a one-step emulsion system using a dieth.lzinc and 1,10-ph.nanth.oline complex. Th. reaction conditions were investigated by varying temperature and initiator to monomer ratio. Fourier transform infrared (FTIR) spectrum, th.rmogravimetric analysis (TGA), and scanning electron microscopy (SEC) tech.iques were used to ch.racterize th. structure, th.rmal stability, and surface morph.logy of th. obtained product, respectively. Grafting of MMA onto silk increased th. th.rmal stability of silk. Th. FTIR spectrum and SEM images provided furth.r evidence th.t MMA h.s been successfully grafted onto th. silk fiber. A peak ascribed to th. C=O stretch.ng vibration of MMA was detected in th. FTIR spectrum of grafted silk fiber, wh.ch.was not present in th. spectrum of pure silk fiber. Moreover, th. SEM images illustrated th. increase in diameter and surface rough.ess of grafted silk compared with.pure silk. Lastly, th. dyeing performance of th. modified silk was significantly increased.

A long-pulse plasma disch.rge for more th.n 30 min. was ach.eved on th. Large h.lical Device （Lh.）. A plasma of ne = 0.8 × 10^19 m^-3 and T10 = 2.0 keV was sustained with.PICh.= 0.52 MW, PECh.= 0.1 MW and averaged PNBI = 0.067 MW. Total injected h.ating energy was 1.3 G J, wh.ch.was a quarter of th. prepared RF h.ating energy. One of th. keys to th. success of th. experiment was a dispersion of th. local plasma h.at load to divertors, accomplish.d by sh.fting th. magnetic axis inward and outward.

Th. T cell dependence of polyclonal B lymph.cyte activation (PBA) induced by one of th. most important periodontopath.c bacteria, Actinomyces Viscosus T14V, was investigated. h.man PBL, togeth.r with.Av-sup, were cocultured with.ut or with.anti-IL-2 and IL-6 monoclonal antibodies for 6 days, and cultural supernatants were h.rvested every 12 h.urs for measuring IgG, IgM, IL-2 and IL-6 activity. Th. results sh.wed th.t (1) Av-sup was able to activate h.man periph.ral B lymph.cytes polyclonally and induce th.m to synth.size immunoglobulins; (2) Av-sup could also induce h.man PBL to produce IL-2 and IL-6 , but peaks of activity of both.IL-2 and IL-6 appeared earlier th.n th.se of IgG and IgM; (3) anti-IL-2 and anti-IL-6 monoclonal antibodies could obviously depress th. production of IgG and IgM, respectively, and furth.rmore, combined application of th.se two monoclonal antibodies could almost completely block th. synth.sis of IgG and IgM. All th. data indicated th.t h.man PBA induced by Av-sup evidently de

In th.s study,th. mech.nism of th. reduction-diffusion reaction in a Sm-Fe binary system at low temperature was studied to investigate th. possibility of synth.sis of a Fe-rich.TbCu_(7)-type SmFe_(x)(x>9)by th. low-temperature diffusion-reduction(LTRD)process using LiCl-KCl eutectic molten ***,th. Sm-Fe ph.se transformation depending on th. Sm-Fe composition,th. LTRD temperature,and time was investigated,and it is found th.t th. obtained metastable ph.se is only TbCu_(7)-type SmFe_(~8.5),wh.ch.is not a Fe-rich.*** Fe content does not ch.nge even after an expended LTRD process,and th. metastable TbCu_(7)-type SmFe_(~8.5)tends to transform to th. stable Sm_(2)Fe_(17)*** addition,it is found th.t th. Sm-Fe ph.se starts to synth.size from th. Sm-rich.ph.se in th. order of SmFe_(2),SmFe_(3),and SmFe_(8.5)as th. LTRD temperature increases(wh.n th. time was 10 h.or th. LTRD time increases(wh.n th. temperature was 550℃).Core-sh.ll-like particles are observed in th. case of a sh.rt LTRD time,and th. core and th. sh.ll are Fe and th. Sm-rich.Sm-Fe ph.se,respectively,indicating th.t th. Sm-rich.ph.se begins to produce on th. surface of th. Fe *** is difficult to synth.size a Fe-rich.TbCu_(7)-type SmFe_(x)(x>9)ph.se with.th. Sm-Fe binary system,suggesting th.t a different approach.such.as addition of oth.r elements,will be necessary.

We propose a new model with.flavor-dependent gauged U(1)B-L1×U(1)B-L2-L3symmetry in addition to th. flavor-blind symmetry in th. Standard Model. Th. model contains th.ee righ.-h.nded neutrinos to cancel gauge anomalies and several h.ggs bosons to construct th. measured fermion masses. We sh.w th. generic features of th. model and explore its ph.nomenology. In particular, we discuss th. current bounds on th. extra gauge bosons from th. K and B meson mixings as well as th. LEP and Lh. data, and focus on th.ir contributions to th. lepton flavor violating processes of ?i+1→?iγ(i=1,2).
