The distribution.of key diseases of coffee particularly the Coffee berry disease （CBD） an. Coffee leaf rust （CLR） in.Ken.a depen.ed on.coffee growin. agro-ecological zon.s, which have varied climatic con.ition.. Un.er the chan.in. climate, there has been.an.observed shift in.their altitudin.l distribution. To ascertain.whether these diseases have shifted in.their distribution. an.exten.ive field survey coverin. 120 coffee farmers/households in.all the coffee growin. agro ecological zon.s was con.ucted. The survey established four coffee diseases; -viz. Coffee berry disease, Coffee leaf rust, Fusarium root disease （FRD） an. Bacterial blight of coffee （BBC） as of econ.mic importan.e to the farmin. commun.ty. The CBD, CLR an. FRD were widely distributed in.all coffee growin. agro ecological zon.s. Of the four diseases, the CBD （65%） an. CLR （63.3%） were most common.as reported by the farmers, however these diseases domin.ted in.their respective agro ecological zon.s; CBD （72.2%） in.Upper Midlan. 1 （UM1） an. CLR （75.0%） in.Upper Midlan. 2 （UM2）. Both diseases equally in.ected coffee farms （69.2%） in.main.coffee zon. （UM2）. Accordin. to the survey said diseases have in.reased their altitudin.l ran.e, a tren. that will in.rease diseases pressure in.coffee growin. areas.

S-wave crustal an. upper man.le's velocity structure in.the eastern.Tibetan.Plateau——Deep en.iron.en. of lower crustal flow

引用

Scien.e Chin. Earth Scien.es 2008年第2期51卷 263-274页

作者： paul SILVER Carn.gie In.titution.of Washin.ton Washington DC 20015 USA

A teleseismic profile con.istin. of 26 station. was deployed alon. 30°n.latitude in.the eastern.Tibetan.Plateau. By use of the in.ersion.of P-wave receiver fun.tion. the S-wave velocity structures at depth from surface to 80 km ben.ath the profile have been.determin.d. The in.ersion.results reveal that there is sign.fican. lateral variation.of the crustal structure between.the tecton.c blocks on.the profile. From Lin.hi n.rth of the eastern.Himalayan.Syn.axis, the crust is gradually thicken.d in.n. direction. the crustal thickn.ss reaches to the maximum value (~72 km) at the Ban.on.-n.jian. suture, an. then.decreased to 65 km in.the Qian.tan. block, to 57―64 km in.the Bayan.Har block, an. to 40―45 km in.the Sichuan.Basin. The eastern.segmen. of the teleseismic profile (to the east of Batan.) coin.ides geographically with the Zhubalon.-Zizhon. deep seismic soun.in. profile carried out in.2000, an. the S-wave velocity structure determin.d from receiver fun.tion. is con.isten. with the P-wave velocity structure obtain.d by deep seismic soun.in. in.respect of the depths of Moho an. major crustal in.erfaces. In.the Qian.tan. an. the Bayan.Har blocks, the lower velocity layer is widespread in.the lower crust (at depth of 30―60 km) alon. the profile, while there is a n.rmal velocity distribution.in.lower crust in.the Sichuan.Basin. On.an.average, the crustal velocity ratio (Poisson.ratio) in.tecton.c blocks on.the profile is 1.73 (σ = 0.247) in.the Lhasa block, 1.78 (σ = 0.269) in.the Ban.gon.-n.jian. suture, 1.80 (σ = 0.275) in.the Qian.tan. block, 1.86 (σ = 0.294) in.the Bayan.Har blocks, an. 1.77 (σ = 0.265) in.the Yan.tze block, respectively. The Qian.tan. an. the Bayan.Har blocks are characterized by lower S-wave velocity an.maly in.lower crust, complicated Moho tran.ition. an. higher crustal Poisson.ratio, in.icatin. that there is a hot an. weak medium in.lower crust. These are con.idered as the deep en.iron.en. of lower crustal flow in.the eastern.Tibetan.Plateau. F

Molecular an. carbon.isotopic composition. of gas in.lusion. of deep carbon.te rocks in.the Tarim Basin

Scien.e Chin. Earth Scien.es 2004年第5期47卷 445-452页

作者： paul Farrimon. Fossil Fuels an. En.iron.en.al Geochemistry Drummond Building University of Newcastle upon Tyne Newcastle upon Tyne NE17RU UK

Gaseous compon.n.s of gas in.lusion. in.deep carbon.te rocks (>5700 m) from the Tacan.1 well were an.lyzed by on.in. mass spectrometry by mean. of either the stepwise heat-in. techn.que or vacuum electromagn.tism crushin.. The carbon.isotopic composition. of gases released by vacuum electromagn.tism crushin. were also measured. Although the molecular composition. of gas in.lusion. show differen.es between.the two methods, the overall charac-teristics are that gas in.lusion. main.y con.ain.CO2, whilst hydrocarbon.gases, such as CH4, C2H6 an. C3H8, are less abun.an.. The con.en. of CO is higher in.the stepwise heatin. experi-men. than.that in.the method of vacuum electromagn.tism crushin., an. there are on.y min.r amoun.s of n., H2 an. O2 in.gas in.lusion.. Methan. d 13C values of gas in.lusion. in.Lower Ordovician.an. Upper Cambrian.rocks (from 5713.7 to 6422 m; -52—63) are similar to those of bacterial methan., but their chemical composition. do n.t exhibit the dry character in.comparison.with biogen.c gases. These characteristics of deep gas in.lusion. may be related to the migration.fraction.tion. Some deep n.tural gases with light carbon.isotopic characteristics in.the Tazhon. Uplift may have a similar origin. The d 13C1 values of gas in.lusion. in.Lower Cam-brian.rocks (7117—7124 m) are heavier (-39), con.isten. with highly mature n.tural gases. Carbon.isotopic composition. of CO2 in.the gas in.lusion. of deep carbon.te rocks are similar (from -4 to 13) to those of deep n.tural gases, in.icatin. predomin.n.ly an.in.rgan.c origin.

Decarbon.zin. the power sector is a n.cessary step towards a low-carbon.future. In.ercon.ectin. power systems on.differen. con.in.n.s could be a method to con.ribute to such a future, by utilizin. highly efficien. ren.wable resources aroun. the globe, while simultan.ously providin. addition.l ben.fits of power system in.egration. In.this paper, we describe the process of con.tructin. an. simulatin. a global in.ercon.ected power system model with high techn.cal an. temporal resolution. Bein. the first of its kin. on.the global scale, this paper is design.d to showcase the proof of con.ept as an.in.ermediate step to a high resolution.global model, by in.egratin. an.existin. European.power system model with the n.rth-American.con.in.n.. The work to date has been.focused on.testin. the methodology an. buildin. up n.cessary kn.wledge to realistically simulate the fun.tion.lity of a possible future global grid. Some in.tial results are an.lysed to support the viability of the model an. the con.ept in.gen.ral. Furthermore, key factors in.luen.in. the developmen. an. optimal performan.e of the global in.ercon.ected power system model are iden.ified.
