A des.gn method of a negative refractive index for free s.rface water waves.in deep water is.pres.nted. To obtain a condition of a negative index, an analogy between water waves.in a water channel and electric waves.in an electric circuit is.employed. An analytical s.lution of waves.around a periodic array of rectangular columns.is.obtained by a circuit analys.s. Attention is.not focus.d on columns.but a s.ace among columns. and then the s.ace is.regarded as.the water channel. Therefore, the circuit analys.s.can be applied to water waves. One channel is.treated as.a unit s.ructure and a number of channels.are periodically cas.aded as.a network. The negative refraction and backward waves.by a network of the water channels.are s.own. s.nce the negative refraction might occur even around s.mple periodic s.ructures. it is.meaningful to unders.and wave phenomenon around offs.ore s.ructures.and develop innovative technology.

Inflammatory bowel dis.as.(IBD) res.lts.from a complex s.ries.of interactions.between s.s.eptibility genes. the environment, and the immune ***, s.me s.udies.provided s.rong evidence that the proces. of autophagy affects.s.veral as.ects.of mucos.l immune res.ons.s. Autophagy is.a cellular s.res. res.ons. that plays.key roles.in phys.ological proces.es. s.ch as.innate and adaptive immunity, adaptation to s.arvation, degradation of aberrant proteins.or organelles. antimicrobial defens., and protein s.cretion. Dys.unctional autophagy is.recognized as.a contributing factor in many chronic inflammatory dis.as.s. including IBD. Autophagy plays.multiple roles.in IBD pathogenes.s.by altering proces.es.that include intracellular bacterial killing, antimicrobial peptide s.cretion by Paneth cells. goblet cell function, proinflammatory cytokine production by macrophages. antigen pres.ntation by dendritic cells. and the endoplas.ic reticulum s.res. res.ons. in enterocytes. Recent s.udies.have identified s.s.eptibility genes.involved in autophagy, s.ch as.NOD2, ATG16L1, and IRGM, and active res.arch is.ongoing all over the world. The aim of this.review is.a s.s.ematic apprais.l of the current literature to provide a better unders.anding of the role of autophagy in the pathogenes.s.of IBD. Unders.anding thes. mechanis.s.will bring about new s.rategies.for the treatment and prevention of IBD.

Volumetric recombinationis.induced in He plas.a by puffing of He or H_2. In the He puffing cas., the reduction of the ionflux is.dominated by the electron-ion recombination. In the H_2 puffing cas., however, it is.ominated by the molecule-as.is.ed recombination (MAR), which is.characterized by the dis.ppearanceof the Helium Rydberg s.ectra and by the exis.ence of the hydrogen negative ions. Currentachievement and the future pros.ect are des.ribed.

The Pb-monitoring program was.extended for 6 years.from 2002 to 2007 at 17 repres.ntative urban s.tes.（6 traffic, 5 indus.rial, and 6 res.dential s.tes., and 3 s.burban s.tes.to as.es. the lead pollution in fine particulate matter （PM2.5） after phas.ng out leaded gas.line in s.anghai. Compared with Pb levels.reported in other places. the Pb pollution in s.anghai is.s.ill s.rious.after phas.ng out leaded gas.line, which remains.at high concentration range （213-176 ng/m^3） in PM2.5 in winter. s.gnificant s.atial variation of Pb concentrations.and s.rong s.as.nal variation of higher Pb concentration in winter than that in s.mmer were detected. The s.ze dis.ribution of Pb in particulate matter has.a unimodat mode that peaks.at approximately 0.154-1.59 μm particle diameter, indicating that Pb is.mainly concentrated in fine fraction. Lead in the fine fraction is.enriched by a factor of 103-104 relative to Pb abundance in crus.. Eight categories.of Pb pollution s.urces.were identified in the PM2.5 in the winter of 2007 in s.anghai. The important emis.ion s.urces.among them are vehicle exhaus. derived from combus.ion of unleaded gas.line, metaUurgic indus.ry emis.ion, and coal combus.ion emis.ion.
