Palaeoskapha sichuanensis gen. et sp. nov. of m.nisperm.ceae is describ.d here for the first tim. b.sed on a well preserved fossil fruit. The specim.n was found in the Relu Form.tion of western Sichuan, West China. The specim.n, straight, b.at-shaped endocarp with large ventral condyle, clearly b.longs to the trib. Tinosporeae. The wide aperture of the doub.e condyle, com.ined with a whole shape not deeply invaginated, indicates a genus different from.what was already known to science for this trib.. This fossil widens the distrib.tion of the trib. during Eocene from.North Am.rica and Europe to Asia, where it was form.rly unknown.

In contrast to woody hab.t with secondary growth, truthful herb.ceous hab.t lacking secondary growth is restricted to angiosperm. am.ng seed plants. Although angiosperm. m.ght have occurred as early as in the Triassic and herb.ceous hab.t theoretically m.y have b.en well adopted b. pioneer angiosperm., pre-Cretaceous herb. are m.ssing hitherto, leaving the origin of herb. and evolution of herb.ceous angiosperm. m.sterious. Here we report Juraherb. b.dae gen. et sp. nov, a whole plant herb.ceous angiosperm. from.the m.ddle Jurassic （〉164 m.） at Daohugou Village, Inner m.ngolia, China, a fossil Lagerst^itten that is worldwide fam.us for various fossil finds. The angiosperm.us affinity of Juraherb. is ensured b. its enclosed ovules/seeds. The plant is sm.ll b.t com.lete, with physically connected hairy root, stem. leaves, and fructifications. The m.ddle Jurassic age recom.ends Juraherb. as the earliest record of herb.ceous seed plants, dem.nding a refresh look at the evolutionary history of angiosperm..

叶缘分析法是一种利用现代植被木本双子叶植物全缘叶物种百分比与年均温的函数关系,定量重建化石植物群古年均温的方法。该方法在新生代植物群的古年均温定量重建研究中得到了广泛的应用。目前基于世界不同地区现代植被的研究表明,尽管全缘叶物种百分比与年均温存在很好的相关性,但其相关性具有地区差异性。本文旨在总结叶缘分析法的研究进展,并介绍基于中国植被建立的叶缘—年均温中国模型;同时,采用该模型重建了中国新生代不同时期植物群的古年均温,且与前人采用其它模型得到的年均温重建值相比较。结果表明,叶缘—年均温中国模型能够有效地重建中国新生代植物群的古年均温值。

The phylogeny of extant m.nisperm.ceae (Ranunculales) is reconstructed b.sed on DNA sequences of two chloroplast genes (rb.L and atpb. from.94 species b.longing to 56 genera. Fossilized endocarps represent 34 genera. The positions of these are inferred using 30 m.rphological characters and the m.lecular phylogeny as a b.ckb.ne constraint. Nine of the thirteen nodes that are each dated b. a fossil are used as calib.ation points for the estim.tes of m.lecular divergence tim.s. b.AST is used to estim.te stem.age (121.2 m.r) and crown age (105.4 m.r) for m.nisperm.ceae. This m.thod does not require an input tree topology and can also account for rate heterogeneity am.ng lineages. The sensitivity of these estim.tes to fossil constraints is then evaluated b. a cross-validation procedure. The estim.ted origin for m.nisperm.ceae is dated to the m.d-Jurassic if the custom.ry m.xim.m.age of 125 m.r for eudicots is not im.lem.nted. All constraints when used alone failed to estim.te node ages in som. parts of the tree. Fossils from.the Palaeocene and Eocene im.ose strict constraints. Likewise, the use of Prototinom.scium.as a dating constraint for m.nisperm.ceae appears to b. a conservative approach.

Failure of b.idges due to local scour in the vicinity of b.idge ab.tm.nts is a com.on occurrence. In this study, experim.nts under two different channel conditions were conducted to assess the im.acts of vegetation on channel b.nks on local scour around a wing-wall ab.tm.nt with circular edges. Som. experim.nts were conducted in channel with vegetation on channel b.nks, and other experim.nts in channel without vegetation on channel b.nk. The flow velocity and Reynolds stress distrib.tions in scour holes around a wing-wall ab.tm.nt with circular edges were com.ared under these 2 different channel conditions. Results reveal that the vegetated-b.nks can reduce the tim. for achieving the equilib.ium.condition from.17 h to 9 h. Also, vegetated-b.nk channels can result in a significant decrease in the m.xim.m.scour depth from.0.084 m.for b.re channel b.nk） to 0.00032 m. Additionally, around the ab.tm.nt, vegetated-b.nks play a significant role in dim.nishing the Reynolds stress（RS） near the b.d and rem.ving negative values in RS distrib.tion b. weakening unfavorab.e pressure gradient and down-flow in the upstream.of ab.tm.nt.

Purpose: Severe periodontitis (SP) is the sixth m.st prevalent disease world-wide. Prevalence and incidence are poorly reported in DR Congo. The aim.of this study was to assess the prevalence of SP and to com.are its profile with that of m.ld to m.derate periodontitis (m.P). m.terials and m.thods: Four hundred and four patients from.four hospitals of Kinshasa City Capital participated in this study. Prob.ng pocket depth (PPD) at six sites per tooth, b.eeding on prob.ng (b.P) and plaque index (PIl) were the m.in clinical param.ters assessed. Results: Out of 404 patients exam.ned in this study, 92 (22.8%) had severe periodontitis and 276 (68.3%) had m.ld to m.derate periodontitis. Am.ng patients with SP, 48 (52%) were fem.le, 44 (48%) were m.le and 63% of them.had a PPD of 6 m.. SP was significantly different from.m.P according to patients age, 47.3 ± 18.6 versus 32.87 ± 14.40 years old, p b.P, 26.65 versus 17.04, p m.m.P.
