加州海啸地球科学家与联邦、州和地方政府应急管理人员密切合作来帮助沿海社区防范海啸发生前、海啸过程中、海啸发生后产生的潜在影响。对于远程海啸,来自美国国家海洋和大气管理局(National Oceanic and.At m.spheric Ad.inistration,简称NOAA)西海岸和阿拉斯加海啸预警中心的科学信息(预测模型、浪高、首波到达时间等)是可以利用的。加州应急管理人员必须以简洁明了的方式将海啸信息传达给最终安排在他们的管辖区采取适当应急措施的地方官员。在2009年9月29日萨摩亚海啸预警中,来自加州地质调查局和洪堡州立大学(Hum.old. State University)的地球科学家在海啸来临之前为加州应急管理处在与美国国家海洋和大气管理局与其他州和地方应急管理人员进行的远程会议的信息传输方面提供了技术支持。加州地球科学家收集了一些附加的背景资料用于预测美国国家海洋和大气管理局预测模型所没有覆盖到的地区的潮汐条件和浪高。在应急响应过程中,加州地球科学家的参与明确了哪些地区处于危险中,哪些地区遭受海啸袭击的风险低。加州地球科学家参与未来海啸应急响应的行动包括以下方面:与美国国家海洋和大气管理局密切合作来简化其海啸警报信息的传递流程并扩展其预测模型的覆盖面;②为地方应急管理人员制作包括已经存在的海啸的情景资料,作为每次海啸事件的参考;③建立一个州级信息共享中心和一支海啸前应急响应队,以协助地方官员一起观测和报道海啸的影响。

The research of rare earths for the synthesis of m.terials with im.roved.m.chanical perform.nce is of great interest when they are consid.red.for potential applications in the autom.tive ind.stry. In this regard. the effect on the m.chanical properties and.m.crostm.ture of the autom.tive A356 alum.num.alloy reinforced.with 0.2 （wt.%） AI-6Ce-3La （ACL） was investigated. The ACL was ad.ed.to the m.lted.A356 alloy in the as-received.cond.tion and.processed.by m.chanical m.lling. In the second.route, the effect of the ACL processed.by m.chanical m.lling and.powd.r m.tallurgy techniques was investigated. and.com.ared.with the results ob- tained.from.the A356 alloy strengthened.with ACL in the as-received.cond.tion. m.crostm.tural properties were evaluated.by m.ans of X-ray d.ffraction in ord.r to observe the solubility of Ce/La in the A1 m.trix. In ad.ition, electron m.croscopy was em.loyed.in or- d.r to investigate the effect of m.lling tim. on the size and.m.rphology of La/Ce phase und.r m.lling process. m.chanical properties of the A356 alloy m.d.fied.with ACL were m.asured.by hard.ess and.tensile test. For com.arison unm.d.fied.specim.ns of the A356 were characterized.accord.ng to the previous proced.re. The m.crostructural and.m.chanical characterization was carried.out in specim.ns alter solution and.artificial aging. Observations in scanning electron m.croscopy ind.cated.a hom.geneous d.spersion of La/Ce phases by using both routes; however, m.chanical results, in the m.d.fied.A356 alloy with the ACL in the as-received.cond.- tion, showed.an im.rovem.nt in the m.chanical perform.nce of the A356 alloy over that reinforced.with the ACL m.chanically m.lled.

Objective: Ped.atric jaund.ce is caused.by various cond.tions. Although som. d.ta is available on this issue, d.ta from.m.li is insufficient. The present retrospective observational stud. was an attem.t to d.term.ne the etiology of ped.atric jaund.ce in the ped.atric d.partm.nt of Gabriel Touré teaching hospital in Bam.ko, m.li. m.thod.: We reviewed.all ped.atric patients with jaund.ce who were hospitalized.and.treated.in this d.partm.nt during January 1 to December 31, 2016 (n = 168). Result: Pediatric jaundice patients accounted for 1.88% of the hospitalized patients, with median age of 6 years and male/female ratio being 1.6. Infectious, cholestatic, and hemolytic jaundice accounted for 75%, 11% and 10%, respectively. Malaria and sickle cell disease accounted for 67% and 9%, respectively. Hepatomegaly and splenomegaly were observed in 49 (29%) and 23 (13.7%) patients, respectively. Of 168, 9 patients died. Conclusion: Infectious jaundice, especially jaundice due to malaria, was the most frequent. However, variety of etiologies was observed, of which the practitioners should be awarem.ly:Verd.na;">. The observation presented.here m.y becom. fund.m.ntal d.ta in health-policy m.king in this area.

Introd.ction: Cervico-isthmic pregnancy is rare, and serious because of its hemorrhagic complication. Its management varies according to the teams. Observation: We report a case of cervico-isthmic pregnancy on a cesarean scar. This is a 35-year-old, G2P2, who consulted for bleeding from the 1st trimester of pregnancy. m.="_Hlk80358912">The clinical examination found a minimal uterine bleeding. The diagnosis was made by a vaginal ultrasound which found a cervico-isthmic implantation of the pregnancy on the caesarean scar. A protocol of Mifepristone and Misoprostol followed by administration of a single dose of 1 mg/kg of Methotrexate was performed. Cure was obtained 1 month after treatment by negativation of plasma HCG. No bleeding complications were noted. A follow-up ultrasound performed 2 months later showed a uterine vacuity and the presence of an isthmocoele. It was in fact a pregnancy that had implanted in the isthmocoele. Conclusion: Cervico-isthmic pregnancy is rare. His treatment is not codified. Drug management was successful.

Genom. Characteristics of the Cyclophragm. Und.ns Nucleopolyhed.ovirus: A d.stinct Species in Group Ⅰ of Alphabaculovirus

Virologica Sinica 2018年第4期33卷 359-368页

作者： Zheng Zhu Jun Wang Qianran Wang Feifei Yin Xiaoping Liu d.anhai Hou Lei Zhang Haizhou Liu Jiang Li Basil m. Arif Hualin Wang Fei d.ng Zhihong Hu m.nli Wang State Key Laboratory of Virology and.China Center for Virus Culture Collection Wuhan Institute of Virology Chinese Academy of Sciences Wuhan 430071 China Canad.an Forest Service Great Lakes Forestry Centre Sault Ste Marie ON P6A 2E5 Canada

The Cyclophragm. und.ns nucleopolyhed.ovirus （CyunNPV）, a potential pest control agent, was isolated.from.Cyclophragm. und.ns （Lepid.ptera： Lasiocam.id.e）, an im.ortant forest pest. In the present stud., we perform.d.d.tailed.genom. analysis of CyunNPV and.com.ared.its genom. to those of other Group I alphabaculoviruses. Sequencing of the CyunNPV genom. using the Roche 454 sequencing system.generated.142,900 bp with a G ＋ C content of 45%. Genom. analysis pred.cted.a total of 147 hypothetical open read.ng fram.s com.rising 38 baculoviral core genes, 24 lepid.pteran baculovirus conserved.genes, nine Group I Alphabaculovirus conserved.genes, 71 com.on genes, and.five genes that are unique to CyunNPV. In ad.ition, the genom. contains 13 hom.logous repeated.sequences （hrs）. Phylogenetic analysis groups CyunNPV und.r a d.stinct branch within clad. ＂a＂ of Group I in the genus Alphabaculovirus. Unlike other m.m.ers of Group I, CyunNPV harbors only nine of the 11 genes previously d.term.ned.to be specific to Group I viruses. Furtherm.re, the CyunNPV lacks the tyrosine phosphatase gene and.the ac30 gene. The CyunNPV F-like protein contains two insertions of continuous polar am.no acid., one at the conventional fusion peptid. and.a second.insertion at the pretransm.m.rane d.m.in. The insertions are likely to affect the fusion function and.suggest an evolutionary process that led.to inactivation of the F-like protein. The above find.ngs im.ly that CyunNPV is a d.stinct species und.r Group I Alphabaculovirus.

The lower part of Fahd.ne Form.tion outcropping in northeastern Tunisia is repre- sented.by pelagic sequences and.characterized.by an im.ortant siliciclastic fraction that includ.s ra- d.olarian and.organic-rich bed. of Allam.m.m.er. Litho-biostratigraphic analysis based.on planktic foram.nifera and.rad.olaria shows that d.position of organic-rich bed. of Allam.m.m.er is confined.to the m.crohed.ergella rischi Zone through the lower part of Ticinella prim.la Zone. Age d.agnostic rad.olaria recovered.from.these bed. has been id.ntified.to constrain a d.rect age of black shale d.po- sition. The assem.lages can be correlated.with the rad.olarian biochronozone U.A.10-11 ind.cating an Early Albian to early m.d.le Albian in age. Rad.olarian assem.lages com.osed.of species characteris- tic of U.A.10 biochronozone （A. m.ntisserei, d. gracilis） are associated.with rad.olarian taxa belonging to Costata Zone （U.A.9 Pseud.eucyrtis hanni and.Thanarla pseud.d.cora）, which can be correlated.with d.rcourt m.m.er in the Ionian Zone and.Paquier level of the Vocontian Basin （southeast of France）. Biostratigraphic and.abund.nce curves analysis has d.m.nstrated.significant d.versification of cryptocephalic Nassellaria and.Archaeod.ctyom.trae, probably ad.pted.to eutrophic cond.tions that characterized.the Aptian-Albian transition. Ecological cond.tions m.y have governed.the stratigraphic range of m.ny cosm.politan taxa （i.e., Pseud.d.ctyom.trae lod.gaensis） com.ared.with stratigraphic d.stributions schem.s reported.from.other d.m.ins. The tim.ng of black shales d.position was d.a- chronic d.e to local geod.nam.c cond.tions and.upwelling currents d.stribution. The Allam.black shales are correlative with the oceanic anoxic event OAElb which is characterized.by the wid.spread.of supraregionnally organic-rich bed. in the m.d.terranean Tethys basins across the Aptian-Albian transition.
