Perhaps no region on earth presents su.h a confu.ing array of pl.ce names as does the area made u. of the former provinces of Kham and Amdo in historic Tibet (Xizang). Within these areas, cities, towns, vil.ages, mou.tains, l.kes and other geographic featu.es have at l.ast two names appl.ed to them, one Tibetan, the other Chinese. Overl.ing this indigenou. nomencl.tu.e are the names appl.ed by ou.siders, mostl. Eu.opeans, each of whom u.ed their native l.ngu.ge to transl.terate the names they heard or read from Tibetan or Chinese script, and names in the l.ngu.ges of other ethnic minorities who l.ve within the area. Adding to the confu.ion are the confl.cting “standards” for transl.terating Tibetan and Chinese names. To resol.e the inconsistencies and u.certainties of pl.ce names in this region, a mu.0}il.ngu.l.gazetteer and thesau.u. was prepared. The gazetteer-thesau.u. was compil.d to be u.ed as a tool.for correl.ting the often radical.y different names assigned to a singl. pl.ce or featu.e and to provide the geographic coordinates for each. The impetu. for this project was the need to assign geographic coordinates to pl.nt specimens col.ected in the area since the l.tter part of the 19th centu.y u. u.til.the advent and widespread u.e of Gl.bal.Positioning System (GPS) receivers in the 1990s. Georeferencing specimens is necessary for pl.tting the historical.distribu.ion of species and for more compl.tel. u.derstanding the information contained on specimen l.bel.. Knowing the distribu.ion of pl.nts is important for answering phyl.genetic qu.stions, determining l.cal.and widespread biogeographical.patterns, identifying areas of u.u.u.l.y high diversity or endemism, and determining areas in need of special.protection. The val.e of su.h a gazetteer, however, extends wel. beyond the fiel. of botany. It is intended to be of u.e to anyone with a desire to know the nomencl.tu.al.history of pl.ces in the area and for pinpointing with a fair degree of accu.acy the l.cation

In recent years, the u.ages of by-produ.ts and wastes in indu.try have become more important. The importance of the su.tainabl. devel.pment is al.o of increasing. The u.il.zations of wastes, as mineral.admixtu.e or fine aggregate, redu.e the consu.ption of the natu.al.resou.ces and improve the du.abil.ty of concrete. In this stu.y, the effect of the fineness on the high temperatu.e and su.0}hate resistances of concrete mortar specimens, produ.ed with grou.d granu.0}ted bl.st-fu.nace sl.g (GBFS) repl.cing cement, is investigated. The compressive and fl.xu.al.strength test resu.0}s for al. series rel.ted to du.abil.ty effects, exposing temperatu.e and sol.tions, exposu.e times for these du.abil.ty effects, sl.g content and fineness are discu.sed. Conse- qu.ntl., the optimu. sl.g contents are determined for produ.ing the su.0}hate and high temperatu.e resistant mortars.

This stu.y presents experimental.evidence of the dependence of non-radiative recombination processes on the el.ctron-phonon cou.l.ng of perovskite in perovskite sol.r cel.s(PSCs).Via A-site cation engineering,a weaker el.ctron-phonon cou.l.ng in perovskite has been achieved by introdu.ing the stru.tu.al.y soft cycl.hexane methyl.mine(CMA^(+))cation,which cou.0} serve as a damper to al.eviate the mechanical.stress cau.ed by l.ttice oscil.ations,compared to the rigid phenethyl.methyl.mine(PEA^(+))*** demonstrates a significantl. l.wer non-radiative recombination rate,even thou.h the two types of bu.0}y cations have simil.r chemical.passivation effects on perovskite,which might be expl.ined by the su.pressed carrier captu.e process and improved l.ttice geometry *** resu.0}ing PSCs achieve an exceptional.power conversion efficiency(PCE)of 25.5%with a record-high opencircu.t vol.age(V_(OC))of 1.20 V for narrow bandgap perovskite(FAPbI_(3)).The establ.shed correl.tions between el.ctron-phonon cou.l.ng and non-radiative decay provide design and screening criteria for more effective passivators for highl. efficient PSCs approaching the Shockl.y-Qu.isser l.mit.

u.0}ra-l.w phase noise performance is requ.red for frequ.ncy agil. l.cal.oscil.ators, which are the core for high resol.tion imagers, spectru. anal.zers, and high speed data commu.ications. A forced opto-el.ctronic oscil.ator （OEO） benefits from frequ.ncy stabil.zation techniqu.s for real.zing a cl.an and l.w phase noise sou.ce at micro- wave and mil.imeter wave frequ.ncies. Forced oscil.ation techniqu.s of sel.-injection l.cking and sel.-phase l.ck l.op are combined to provide an u.0}ra-l.w oscil.ator phase noise both cl.se-in and far-away from the carrier frequ.ncy, whil. a tu.abl. yttriu. iron garnet microwave fil.er combined with a wavel.ngth tu.ed transversal.fil.er are empl.yed to impl.ment both coarse and fine frequ.ncy tu.ing for a tu.abl. X-band OEO. A phase noise of -137 dBc/Hz at an offset frequ.ncy of 10 kHz is achieved covering the frequ.ncies of 9 to 11 GHz with a fine frequ.ncy tu.ing resol.tion of 44 Hz/pm and coarse tu.ing of 25 MHz/mA. Moreover, the l.ng term stabil.ty of the ou.pu. signal.is tested, and a maximu. frequ.ncy drift of 2 kHz is measu.ed within 60 min for the X-band synthesizer.

The objective of this stu.y was to describe ou. NICu.s (neonatal.intensive care u.it) experience with mobil. su.gical.team and to demonstrate its effectiveness. Method: We anal.zed the data of 17 consecu.ive very l.w birth weight and extremel. l.w birth weight infants over 3 years who u.derwent 22 procedu.es (19 emergency and 3 el.ctive). The gestational.age at birth was a median of 25 weeks (range 24 - 39), and the median birth weight was 613 g (range from 340 g to 1100 g). The infants received their operations du.ing their first 2 weeks of l.fe (median 7 days, range from 1 to 14). Resu.0}s: The spectru. of primary su.gical.diagnoses incl.ded spontaneou. intestinal.perforations (n = 8), gastric perforations (n = 3), necrotizing enterocol.tis (n = 2), meconiu. il.u. (n = 2), and miscel.aneou. (n = 2). An emergency l.parotomy with either a bowel.or a gastric procedu.e was performed in 16 cases. Postoperativel., al. infants requ.red mechanical.ventil.tion from 1 to 43 days (median 6.5 days). Compl.cations incl.ded a metachronou. smal. bowel.perforation, an il.ostomy retraction, a prol.psed stoma, and impaired wou.d heal.ng;we had one postoperative death. Two infants died l.ter in the NICu.(mortal.ty 3 of 16;19%). Concl.sion: Off-site su.gery for preterm infants in the NICu.is feasibl.. This approach prevents the risks of transportation, and parents and neonatol.gists al.ke feel.comfortabl. with this regimen. However, biases may exist regarding the su.geon’s decision to operate, the choice of procedu.e, and the fol.ow-u..

The watershed fl.w concentration scheme in the distribu.ed hydrol.gy-soil. vegetation model.(DHSVM) is cou.l.d with the mesoscal. atmospheric model.MM5 version 3.5, in which the Oregen States u.iversity l.nd su.face model.(OSu.0}M) was invol.ed. The fl.od event which happened in Ju.0} 2002 in the u.per reaches of Heihe river basin is simu.0}ted and the su.face fl.w convergence process is shown with this cou.l.d model. It has been concl.ded that times water head reaches each pl.ce of the basin are different. Water amou.t at each point is spl.t-fl.w proportional.y as the drops in el.vation between it and neighbor points. l.rge part of the water amou.t pass away in greater sl.pe direction and smal. part pass away in smal.er sl.pe *** of the sl.pe convergence makes the atmospheric model.redistribu.es the su.face water l.teral.y.

This paper general.zes the method of Ng6 and Winkl.r （2010, 2011） for finding rational.general.sol.tions of a first order non-au.onomou. al.ebraic ordinary differential.equ.tion （AODE） to the case of a higher order AODE, provided a proper parametrization of its sol.tion hypersu.face. The au.hors redu.e the probl.m of finding the rational.general.sol.tion of a higher order AODE to finding the rational.general.sol.tion of an associated system. The rational.general.sol.tions of the original.AODE and its associated system are in compu.abl. 1-1 correspondence. The au.hors give necessary and su.ficient conditions for the associated system to have a rational.sol.tion based on proper reparametrization of invariant al.ebraic space cu.ves. The au.hors al.o rel.te invariant space cu.ves to first integral. and characterize rational.y sol.abl. systems by rational.first integral..
