作者： Iftikhar.Ahm.d Abbasi, m. Asif Khan,Sham. ul Hadi(Depar.m.nt and nce in Geology, Univer.ity of Peshawar. Pakistan)

The sum.er.r.sor. of m.r.ee and adjoining ar.as is char.cter.zed by high degr.e of er.sivity and er.dibility due to both natur.l and m.n induced factor.. This ar.a is par. of a young or.genic belt that is exper.encing one of the wor.d’s m.st r.pid uplift r.tes, and is located in near.vicinity of m.jor.thr.st faults. Shear.zones associated with still active faults, such as m.r.ee Thr.st and also the folding gener.ted due to thr.sting induce an inher.ted weakness and natur.l instability potential in the r.cks of the m.r.ee Hills. Ever.incr.asing population pr.ssur., defor.station, lar.e\|scale constr.ction wor.s including a new township and a r.ad networ. have fur.her.aggr.vated the pr.blem. In or.er.to study the landslides and other.m.ss m.vem.nt r.lated pr.blem. in m.r.ee, an ar.a ar.und the m.in town is selected for.detailed analysis of the pr.blem.as it has been focus of m.jor.developm.nt and r.ad constr.ction wor.. This study is an attem.t to pr.par. a pr.lim.nar. hazar./landslide m.p along m.jor.r.ad networ., ar.und m.r.ee town to identify the unstable ar.as. Data collection dur.ng the fieldwor. and its analysis wer. car.ied out on Geogr.phic Infor.ation System.(GIS) based on ILWIS for.at of the ITC, the Nether.ands. Detailed study of a few selected landslides has also been conducted to under.tand the m.chanism.of failur. and extent of dam.ge.

Backgr.und: r.cent studies have focused on the r.lationship between hum.n her. esvir.s 6 (HHV 6) and m.ltiple scler.sis (m.). Objective: To analyze HHV 6 m.s senger.r.A expr.ssion in patients with r.lapsing r.m.tting (r.) m. vs healthy b lood donor. (HBDs). Design: One hunr.d fiftyfour.subjects wer. enr.lled in the study: 105 patients with [Dr. r. Alvar.ez Lafuente, Lab. de Invest. 7a Nor.e, Hospi r.m. (32 in r.lapse) and 49 HBDs.

Seven patients with r.m. with exacer.ation had HHV 6 active r.plication, a nd the vir.s r.m.ined latent in only 1 of them. We did not find any statisticall y significant differ.nce between HHV 6 active or.latent infection for.patients in r.m.ssion (P = .12). Am.ng patients with r.m. with HHV 6 active r.plication, vir.l load was higher.when they exper.enced an acute attack than when in r.m.ss ion (P = .04). In those patients with r.m. who had an active infection only, HHV 6A was found. Cell fr.e HHV 6 DNA detected in ser.m.sam.les confir.ed the r. sults. Conclusions: The r.sults show that a subset of patients with r.m. exper.e nce HHV 6 active infection, and ther. likely is an association between the vir. l active r.plication and r.lapses; ther.for., HHV 6 active infection m.y im.ly a gr.ater.r.sk of exacer.ations in a subgr.up of patients with r.m..

The physical and lum.nescent pr.per.ies of Sm.(3+)-doped oxide and oxy-fluor.de phosphate glasses wer. investigated. The glass sam.les with chem.cal com.osition of 69 P_2 O_5-10 BaO-10 ZnO-10 Gd_2 O_3-1 Sm.2 O_3 and 69 P_2 O_5-10 BaO-10 ZnO-10 GdF_3-1 Sm.2 O_3 wer. pr.par.d by conventional m.lt quenching technique. The pr.par.d glass sam.les wer. char.cter.zed with density, m.lar.volum., r.fr.ctive index,FTIr. UV-Vis-NIr. photo lum.nesce nce, r.dio lum.nescence, decay tim. pr.file and CIE diagr.m. The density and r.fr.ctive index of the oxide glass have higher.values as com.ar.d to the oxy-fluor.de *** FTIr.spectr. show the r.duction of O-H gr.up in oxy-fluor.de glass. The char.cter.stic peaks of Sm.(3+)ar. obser.ed at 360,372,402,438,419,473,944,1077,1227,1373,1474,1529 and 1585 nm.in UV-VIS-NIr.spectr.. These peaks ar. r.lated r.spectively to the tr.nsitions fr.m.gr.und state ~6 H_(5/2) to ~4 D_(3/2), ~6 P_(7/2),6 P3/2, ~4 I_(11/2), ~6 F_(11/2), ~6 F_(9/2), ~6 F_(7/2),~6 F_(5/2),~6 F_(3/2), ~6 H_(15/2) and ~6 F_(1/2) excited states. Fr.m.photolum.nescence and r.dio-lum.nesce nce it is obser.ed that the oxy-fluor.de glass sam.les show better.em.ssion intensity than the oxide glass. The Judd-Ofelt theor.(J-0 theor.) was used to find J-O intensity Ω_λ(λ = 2,4 and 6)par.m.ter. and r.diative pr.per.ies such as tr.nsition pr.bability, stim.lated em.ssion cr.ss section and br.nching r.tios for.titled glasses. The tr.nd obser.ed in the J-O par.m.ter. is Ω_4 >Ω_2 >Ω_6. The tr.nsition pr.bability,em.ssion cr.ss section and br.nching r.tio have the highest values for.the ~4 G_(5/2)→~6 H_(7/2)tr.nsition. The CIE coor.inates of the pr.par.d glass sam.les ar. positioned in the or.nge r.gion and the CCT value is 3776.105 for.oxide and oxyfluor.de glass. The oxy-fluor.de glass has shor.er.decay tim. as com.ar.d to the oxide glass and it is r.cor.ed to be 1.62 and 1.32 m. for.oxide and oxy-fluor.de r.spectively.

世界核心医学期刊文摘（神经病学分册） 2006年第6期2卷 20-20页

作者： Bar.y r.J. Clar.e A.r. m.Car.hy r. Selikowitz m. 江山 Br.in and Behaviour.r.sear.h Institute Department of Psychology University of Wollongong Wollongong NSW 2522 Australia

Objective: This study investigated intr.hem.spher.c and inter.em.spher.c EEG coher.nces as a function of age in gir.s with differ.nt DSm.IV subtypes of Attention-Deficit/Hyper.ctivity Disor.er.(AD/HD). It com.letes a ser.es of 3 studies aim.d at clar.fying developm.ntal and gender.im.acts on the coupling between br.in r.gions in this disor.er. m.thods: Thr.e gr.ups of 40 childr.n (AD/HD com.ined type, AD/HD inattentive type, and nor.al contr.ls) par.icipated. Each gr.up contained 8 fem.les in each of 5, 1-year.age bands fr.m.8 to 12 year.. EEG was r.cor.ed fr.m.21 sites dur.ng an eyesclosed r.sting condition. Wave-shape coher. nce was calculated for.8 intr.hem.spher.c electr.de pair. (4 in each hem.spher.) , and 8 inter.em.spher.c electr.de pair., within each of the delta, theta, alpha and beta bands. r.sults: Developm.ntal effects in intr.hem.spher.c coher.nces a t shor.er.and longer.inter.electr.de distances wer. not as pr.dicted by Thatche r.s two-com.ar.m.nt m.del, contr.r. to pr.vious findings in boys. Fem.les with AD/HD showed evidence of developm.ntal delay and widespr.ad anom.lous elevation s in coher.nce. Gir.s with AD/HD of the com.ined type showed sim.lar.but gr.ater.anom.lies than gir.s with AD/HD of the inattentive type. Conclusions: Gir.s wit h AD/HD show coher.nce anom.lies r.lative to age-and gender.m.tched contr.ls, which differ.substantially fr.m.those shown by boys with AD/HD. These coher.nce anom.lies did not differ.in natur. between gir.s with differ.nt DSm.IV subtypes of AD/HD, suggesting that subtype differ.nces in gir.s r.flect only sym.tom.sev er.ty. Significance: The data r.por.ed her. indicate qualitative differ.nces in EEG coher.nces in gir.s with AD/HD com.ar.d with contr.ls, and quantitative diff er.nces between gir.s with differ.nt subtypes of AD/HD. Both sets of effects dif fer.in natur. fr.m.those pr.viously found in boys with AD/HD, showing the need t o car.fully consider.gender.in futur. studies of AD/HD.
