We dem.ns.rated a new type of m.X phas. m.terial, chrom.um.titanium.alum.num.carbide（Cr2TialC2） polym.r film. to generate a pas.ively Q-s.itched erbium.doped fiber las.r（EDFL）. The film.thicknes. was.m.as.red to be around 45 μm. which was.fabricated us.ng the em.edding m.thod with polyvinyl alcohol（PVA） polym.r as.hos.er. The s.turable abs.rber（s.） film.dem.ns.rates.a dual-wavelength pas.ively Q-s.itched EDFL which operates.at 1 531 nm.and 1 560.19 nm. res.ectively. The Q-s.itching puls. duration could be varied from.2.46 μs.to 770 ns. while the repetition rate varied from.92.76 kHz to 106.6 kHz with an increas.ng input pum.ing range from.154 m. to 300 m.. The m.xim.m.output power and puls. energy of 15.05 m. and 141.18 nJ were obtained at the m.xim.m.input power of 300 m., res.ectively.

The age at which a wom.n enters.natural m.nopaus. has.als. been as.ociated to death from.any caus.. m.nopaus. is.a natural com.onent of aging that happens.between the ages.of 45 and 55, with the average m.nopaus.l age being 51. Previous.res.arch has.revealed the age at which wom.n reach m.nopaus., but there is.no evidence to s.pport the link between m.nopaus. and longevity. We m.de a s.udy in as.es.ing the lim.ts.of m.xim.m.lifes.an at m.nopaus.l age in our previous.article. In this.paper, we aim.to predict the m.xim.m.lifes.an of wom.n at m.an m.nopaus.l age.

Thin film. of hydrogenated am.rphous.germ.nium.(a-Ge:H) were prepared by radio frequency glow dis.harge depos.tion at various.s.bs.rate tem.eratures. The hydrogen dis.ribution and bonding s.ruc-ture in a-Ge:H were dis.us.ed bas.d on infrared abs.rption data. The correlation between infrared abs.rp-tion s.ectra and hydrogen effus.on m.as.rem.nts.was.us.d to determ.ne the proportionality cons.ant for each vibration m.de of the Ge-H bonds. The res.lts.reveal that the bending m.de appearing at 835 cm.1 is.as.ociated with the Ge-H2 (dihydride) groups.on the internal s.rfaces.of voids. While 1880 cm.1 is.as.igned to vibrations.of Ge-H (m.nohydride) groups.in the bulk, the 2000 cm.1 s.retching m.de is.attributed to Ge-H and Ge-H2 bonds.located on the s.rfaces.of voids. For film. as.ociated with bending m.des.in the infrared s.ectra, the proportionality cons.ant values.of the s.retching m.des.near 1880 and 2000 cm.1 are found to be lower than thos. of film. which had no corres.onding bending m.des.

We inves.igated the floris.ic com.os.tion, woody s.ecies.divers.ty and s.atial dis.ribution of trees.in a tropical wet evergreen fores. in Kaptai national park in Chittagong Hill Tracks. Banglades.. We recorded 25 fam.lies. 37 genera, 40 s.ecies.and 1771 woody individuals.in a 0.09 ha plot. Euphorbiaceae and m.raceae were the m.s. s.ecies. rich fam.lies. and Cas.anops.s. Ficus.and Term.naliawere the m.s. s.ecies.rich genera. Burs.ra s.rrata Wall. ex Colebr. was.the dom.nant s.ecies.in term. of highes. im.ortance value （13%）. Trem. orientalis.（L.） B1 was.typically a light dem.nding s.ecies.as.it appeared in the top can- opy with only one individual having the s.venth highes. IV, but had no regeneration. The expected m.xim.m.num.er of s.ecies.（s.0}x） was.140, indicating that m.ny s.ecies.m.y invade the fores. as.the s.0} is.greater than the recorded total num.er of s.ecies. The nature of the dis.ppear- ance and appearance of s.ecies.in the pres.nt fores. reflects.ins.ability of floris.ic com.os.tion. The values.of s.annon＇s.index H＇ and Pielou＇s.index J＇（evennes.） were 3.36 bit and 0.63, res.ectively.

In addition, a s.m.le area of 200 m. in this.fores. would be s.fficient for m.as.ring the divers.ty indices.H＂ and ,/＇, whereas.the trend of J＇m.y indicate the rate of equality of individuals.am.ng the different s.ecies.decreas.d with increas.ng area.
