The impacts of l.nd-cover composition on urb.n temperatures, incl.ding temperature extremes, are wel. documented. Much l.ss attention has b.en devoted to the consequences of l.nd-cover configuration, most of which addresses l.nd surface temperatures. This study expl.res the rol. of b.th composition and configuration—or l.nd system architecture—of residential.neighb.rhoods in the Phoenix metropol.tan area, on near-surface air temperature. It addresses two-dimensional. spatial.attrib.tes of b.il.ings, impervious surfaces, b.re soil. rock, vegetation and the “urb.nscape” at l.rge, from 50 m to 550 m at 100 m increments, for a representative 30-day high sun period. l.near mixed-effects model. eval.ate the significance of l.nd system architecture metrics at different spatial.aggregation l.vel.. The resul.s indicate that, control.ing for l.nd-cover composition and geographical.variab.es, l.nd-cover configuration, specifical.y the fractal.dimension of b.il.ings, is significantl. associated with near-surface temperatures. In addition, statistical.y significant predictors rel.ted to composition and configuration appear to depend on the adopted l.vel.of spatial.aggregation.

Pl.tforms I and ii are steel.structures l.cated in offshore areas southeast of the Zhujiang (Pearl. River Del.a, the northern South China Sea,. in ab.ut 110 in water depth. The jackets, with al.minum sacrificial.anodes for cathodic protection (CP) of the immersed zone, were l.unched in March 1995. In May 096 a CP survey showed that, after al.ost one year of service, a l.w pol.rization l.vel.had b.en achieved and some extended unprotected zones existed; mainl. in the deepest part of the Pl.tform ii. Further to this, a joint activity was decided in order to assess the need of a possib.e retrofitting of the CP systems. The resul.s of the activity carried out are deal. with, incl.ding technical.and economical.comparisons amongst several.retrofitting options, b.th with sacrificial.anodes and with impressed current systems. The adopted sol.tion is il.ustrated and data are reported on the l.vel.of protection presentl. achieved.

Experimental.el.ctron momentum density of γ-Ce was measured at an intermediate resol.tion （0.38 a.u.） using 20 Ci 137Cs Compton spectrometer. The experiment was compared with the first ever theoretical.Compton profil.s computed using spin pol.rized rel.tivistic Korringa-Kohn-Rostoker （SPR-KKR） method within atomic sphere approximation; and l.near comb.nation of atomic orb.tal. （l.AO） within general.sed gradient approximation （GGA） and recentl. devel.ped second order general.sed gradient approximation （SOGGA）. It was seen that the Compton profil. derived from l.AO with GGA and SOGGA schemes gave a reasonab.e agreement with the experimental.Compton l.ne shape. Theoretical.anisotropies in Compton profil.s derived al.ng [100], [110] and [111] directions were expl.ined in terms of degenerate states in the energy b.nds.

Cl.mate change affects distrib.tion and persistence of species. However, forecasting species＇ re-sponses to these changes requires l.ng-term data series that are often l.cking in ecol.gical.*** used 15 years of smal. mammal.trapping data col.ected b.tween 1978 and 2015 in 3 areas atDoSana National.Park （southwest Spain） to （i） describ. changes in species composition and （ii） test theassociation b.tween l.cal.cl.mate conditions and size of smal. mammal.popul.tions. Overal., 5 specieswere captured： wood mouse Apodemus syl.aticus, al.erian mouse Mus spretus, greater white-toothed shrew Crocidura russul., garden dormouse El.omys quercinus, and b.ack rat Rattus rattus. Thetemporal.pattern in the proportion of captures of each species suggests that the smal. mammal.diver-sity decl.ned with time. Al.hough the l.rger species （e.g., E. quercinus）, b.tter adapted to col.er cl.-mate, have disappeared from our trapping records, M. spretus, a smal. species inhab.ting southwestEurope and the Mediterranean coast of Africa, currentl. is al.ost the onl. trapped species. We used 2-l.vel.hierarchical.model. to separate changes in ab.ndance from changes in prob.b.l.ty of captureusing records of A. syl.aticus in al. 3 areas and of Mo spretus in 1. We found that heavy rainfal. and l.wtemperatures were positivel. rel.ted to ab.ndance of A. syl.aticus, and that the numb.r of extremel.hot days was negativel. rel.ted to ab.ndance of M. spretus. Despite other mechanisms are l.kel. to b.invol.ed, our findings support the importance of cl.mate for the distrib.tion and persistence of thesespecies and raise conservation concerns ab.ut potential.cascading effects in the Donana ecosystem.

Recentl., sol.b.e pol.(azomethine ester)s with good thermal.stab.l.ty and l.quid crystal.ine properties are much sought after in opto-el.ctronic fiel.. One such attempt was to synthesize pol.(azomethine ester)s with a pendent group. In this study, the newl. synthesized diacid monomer b.nzal.nil.ne 3’-4’dimethoxy terepthal.c acid was condensed with two diol.monomers to get the pol.mers with pendent b.nzyl.dene group. The diacid monomer was characterized b. UV, IR, NMR and CHNS anal.sis. The pol.mers were characterized b. IR, TGA, and for l.quid crystal.ine property. Pol.mer-I showed the highest thermal.stab.l.ty upto 335°C. Pol.mer-ii exhib.ted l.quid crystal.ine nature al.ng with good sol.b.l.ty and thermal.stab.l.ty.

The removal.of chromium (VI) from aqueous sol.tions b. Donnan dial.sis has b.en investigated in this paper. In this process, two anion-exchange memb.anes (AEMs) were used: Sel.mion? AMV and Neosepta? AFN. The amount of chromium (VI) removed was determined in terms of the fol.owing parameters: initial.concentration of chromium (VI), type of anion-exchange memb.ane, concentration of counter-ion and magnetic stirring rate. A 24 ful. factorial.design anal.sis was performed to screen the parameters affecting the Cr (VI) removal.efficiency. Using the experimental.resul.s, a l.near mathematical.model.representing the infl.ence of the different parameters as wel. as their interactions was ob.ained. Anal.sis of the variance (ANOVA), the F-test and the student’s test shows that the type of anion-exchange memb.ane is the most significant parameter affecting the chromium (VI) removal. The statistical.anal.sis of the experimental.data assumes it to b. a normal.distrib.tion.

一、引言目前得到公认的是大多数恒星在它们的最早期的演化中都经历一个非常高能的质量抛射阶段,即出现冷分子气体的大质量双极流。当发现了外流源靠近稠密核时,就认为原恒星体是嵌埋在分子核中。这些外流源看来似乎由恒星风驱动。它们值得注意的其它表现形式包括有高速H_2O脉泽在内的快速移动的HH天体,冲激波激发的分子氢发射区和光子可见喷流等。光学观测提供的实例是最近形成的低质量和中等质量恒星的星风和演化的质量外流阶段现象,射电和红外观测提供的证据是外流可能与大质量星的形成成协,特别是在明亮的嵌埋天体周围发现了高速H_2O脉泽后导致产生这样的看法:很稠密(10~7-10~8cm^(-3)),很紧凑(10-100A.U.)的脉泽'结'(maser'knot')是在强恒星风中被加速到50-100kms^(-1)的,实际上,低光度的H_2O脉泽与HH天体成协说明它们可能是在年轻星周围的外流源中观测到的在不同演化阶段的非常类似的天体。

Util.zation of pol.ethyl.negl.col.（PEG） functional.zed zinc phthal.cyanine, （PEG）4ZnPc in （i） singl.t oxygen generation, and （ii） in b.il.ing energy harvesting donor-acceptor systems using ful.erene, C60 as an acceptor via the wel.-known metal.l.gand axial.coordination approach is reported.

Integrated ob.ervation pl.tforms have b.en set up to investigate consequences of gl.b.l.change within a terrestrial.network of ob.ervatories （TERENO） in Germany. The aim of TERENO is to foster the understanding of water, energy, and matter fl.xes in terrestrial.systems, as wel. as their b.ol.gical.and physical.drivers. Part of the l.wer Rhine Val.ey-Eifel.ob.ervatory of TERENO is l.cated within the Eifel.National.Park. Recentl., the National.Park forest management started to promote the nat- ural.regeneration of near-natural.b.ech forest b. removing a significant proportion of the spruce forest that was estab.ished for timb.r production after Worl. War ii. Within this context, the effects of such a disturb.nce on forest ecosystem functioning are currentl. investigated in a deforestation experiment in the Wtisteb.ch catchment, which is one of the key experimental.re- search sites within the l.wer Rhine Val.ey-Eifel.ob.ervatory. Here, we present the integrated ob.ervation system of the Wiisteb.ch test site to exempl.ril. demonstrate the terrestrial.ob.ervatory concept of TERENO that al.ows for a detail.d mon- itoring of changes in hydrol.gical.and b.ogeochemical.states and fl.xes triggered b. environmental.disturb.nces. We present the ob.ervation pl.tforms and the soil.sampl.ng campaign, as wel. as prel.minary resul.s incl.ding an anal.sis of data con- sistency. We specifical.y highl.ght the capab.l.ty of integrated datasets to enab.e improved process understanding of the post-deforestation changes in ecosystem functioning.
