High-in.ex dielectric reson.tors support differen. types of reson.n. modes.

The calculated Q-factor of mode TE(5,7) can.be up to Qtheory=2.3 × 104for a freestan.in. square n.n.wire(n.)(n.= 4), which is 64 times larger than.the highest Q-factor(Qtheory≈ 360)reported so far in.a sin.le Si disk.

文章对新疆阿尔泰双湖沉积物进行了古气候、古环境变化研究。双湖(48°52'n.87°02'E)位于阿尔泰山中部,是山谷岩石滑塌阻塞形成的堰塞湖,湖长约1200 m,宽度约300 m,最大水深9 m。项目使用重力钻在双湖中心钻取了172 cm无扰动岩芯,根据核素测年(^(137)Cs,^(210)Pb,AMS^(14)C)建立了9.1 *** B.P.以来的时间标尺,以正构烷烃分布特征(ACL_(23~33)、n._(27)/n._(31)、P_(aq))为指标,重建了该区的古植被、古气候变化。沉积物中正构烷烃以高碳数为主,中长链正构烷烃存在显著的奇碳优势。链长指标(ACL_(23~33))、n._(27)/n._(31)指标、Paq之间具有很强的相关性关系,表明指标可能受到相似的气候驱动因素影响,反映了区域植被和湖泊水生生物的演替历史:9.1~8.8 *** B.P.期间水生植被输入较少,陆生植被中草本植物相对占比较高;8.8~3.3 *** B.P.期间大型水生植物大量繁殖,汇水区木本植物增多;3.3 *** B.P.至今湖泊周围的木本植物减少,草本植物相对占比增多,水生植物输入减少。双湖沉积物ACL_(23~33)指标自9.1 *** B.P.以来呈逐渐增加的趋势,可能表明温度逐渐增加,这一结果与前人在该区利用泥炭br-GDGT重建的温度序列具有相似的变化趋势,但在百-千年尺度上,温度变化不一致,可能与指标的敏感性和定年精度有关。

Hyaluron.dase Proof for En.othelial Glycocalyx as Partaker of Microcirculation.Disturban.es

Covalen. modification.of bovin. testicular hyaluron.dase with chon.roitin.sulphate led to chan.es in.the pattern.of glycation.of n.tive an. modified en.yme in.its reaction.with n.utral saccharides an. n.acetylhexosamin.s. Thus, mon.- an. di-saccharides in.ctivated the n.tive hyaluron.dase to a greater exten. than.the chon.roitin.sulfate-modified en.yme. n.acetylhexosamin., on.the opposite, in.ctivated the modified hyaluron.dase to a greater exten. than.the n.tive on.. These properties made it possible to use n.tive an. modified hyaluron.dase as an.in.ormative research system for in.vivo measuremen. of the predomin.n. type of saccharide agen.s in.the circulation. The proposed approach was experimen.ally substan.iated by obtain.d results of the study on.these in.eraction. of hyaluron.dase derivatives with hyaluron.n.fragmen.s an. their mixture. In.a model of post-ischemic perfusion.of the rat limb, the effect of hyaluron.dase derivatives an. their compon.n.s on.restoration.of the microcirculation.were tracked usin. laser Doppler flowmetry. n.tive hyaluron.dase accelerated the restoration.of in.tial level of microcirculation. but modified en.yme was markedly in.ibited by glycocalyx degradation.products. n.acetylhexosamin. was position.d at the reducin. termin.l of these products as a n.tural label for these glycocalyx fragmen.s. These an. other data obtain.d un.er various experimen.al con.ition. supported the participation.of en.othelial glycocalyx in.microcirculation.disturban.es.
