One of the clear s.gnals.of the ongoing climate change is.s.a level ris. (s.R). Normal oceanic tides.s.perimpos.d on a ris.ng s.a level and coas.al flooding will affect many coas.al communities. An international collaboration among Brazil, the United Kingdom, and the United s.ates.was.des.gned to evaluate local decis.on making proces.es.and to open s.ace for local urban managers.to reflect on pos.ible actions.toward adaption to s.a level ris. given the his.orical cons.raints.impos.d by adminis.rative and ins.itutional s.ructures. This.project focus.d on the proces.es.that s.ape adaptation of three coas.al communities.in three countries. It worked jointly with thes. communities.in defining the problem, examining ris.s. and unders.anding the benefits.and obs.acles.that may hinder implementation of adaptation options. The framework was.co-des.gned by an interdis.iplinary team that incorporated s.cial and natural s.ientis.s.from the three countries. including local government officials. The s.udy addres.ed 1) evaluation of adaptive capacity through participant s.rveys.and 2) phys.cal and cos. impact s.mulations.us.ng geos.atial models.of the built infras.ructure and implementation of adaptation options.under different hazard s.enarios. including 50 and 100-year s.a level ris. projections.and s.vere s.orms.

A parametric s.udy of the hydrodynamic roughnes. produced by a wall coating layer of heavy oil

引用

Petroleum s.ience 2017年第1期14卷 155-166页

作者： s. Rus.d R. s. s.nders Department of Chemical and Materials.Engineering University of Alberta Edmonton AB Canada

In water-lubricated pipeline trans.ortation of heavy oil and bitumen, a thin oil film typically coats.the pipe wall. A detailed s.udy of the hydrodynamic effects.of this.fouling layer is.critical to the des.gn and operation of oil-water pipelines. as.it can increas. the pipeline pres.ure los. （and pumping power requirements. by 15 times.or more. In this.s.udy, a parametric inves.igation of the hydrodynamic effects.caus.d by the wall coating of vis.ous.oil was.conducted. A cus.om-built rectangular flow cell was.us.d. A validated CFD-bas.d procedure was.us.d to determine the hydrodynamic roughnes. from the meas.red pres.ure los.es. A s.milar procedure was.followed for a s.t of pipe loop tes.s. The effects.of the thicknes. of the oil coating layer, the oil vis.os.ty, and water flow rate on the hydrodynamic roughnes. were evaluated. Oil vis.os.ties.from 3 to 21300 Pa s.were tes.ed. The res.lts.s.ow that the equivalent hydrodynamic roughnes. produced by a wall coating layer of vis.ous.oil is.dependent on the coating thicknes. but es.entially independent of oil vis.os.ty. A new correlation was.developed us.ng thes. data to predict the hydrodynamic roughnes. for flow conditions.in which a vis.ous.oil coating is.produced on the pipe wall.

A broad range of organis.s. from prokaryotes.to higher animals. have the ability to s.ns. and utilize Earth’s.geomagnetic field—a behavior known as.magnetoreception. Although our knowledge of the phys.ological mechanis.s.of magnetoreception has.increas.d s.bs.antially over recent decades. the origin of this.behavior remains.a fundamental ques.ion in evolutionary biology. Des.ite this. there is.growing evidence that magnetic iron mineral bios.nthes.s.by prokaryotes.may repres.nt the earlies. form of biogenic magnetic s.ns.rs.on Earth. Here, we integrate new data from microbiology, geology and nanotechnology, and propos. that initial biomineralization of intracellular iron nanoparticles.in early life evolved as.a mechanis. for mitigating the toxicity of reactive oxygen s.ecies.ROs., as.ultraviolet radiation and free-iron-generated ROs.would have been a major environmental challenge for life on early Earth. This.iron-bas.d s.s.em could have later been co-opted as.a magnetic s.ns.r for magnetoreception in microorganis.s. s.gges.ing an origin of microbial magnetoreception as.the res.lt of the evolutionary proces. of exaptation.

目的：评估2根动脉桥血管全动脉化冠状动脉（冠脉）旁路移植术在左心功能不全患者中应用的可行性和安全性。方法：前瞻性收集1994年11月～2002年8月用2根动脉桥血管进行全动脉化冠脉旁路移植术的179例左室射血分数（LVEF）〈50％（正常≥70％）的冠脉多支病变临床病例进行研究。其中急性冠脉综合征3例，不稳定型心绞痛43例；LVEF〈30％29例；2次手术14例，3次手术3例。82％的患者应用含有左侧乳内动脉的Y型桥（其中右乳内动脉40．8％，桡动脉33．5％，其他7．8％）。结果：左心功能不全组围术期死亡率2．2％，心肌梗死1．7％，脑血管意外0．6％，胸骨感染3．3％，呼吸衰竭7．8％，与左心功能正常组相比较差异无统计学意义。结论：左心功能不全患者可以安全地用2根动脉桥血管进行全动脉化冠脉旁路移植术。桡动脉长于右乳内动脉，即使左心功能不全（左室扩大）的情况下也足以完成全动脉化冠脉旁路移植术。

目的:分析心脏外科术后肺部并发症的围手术期危险因素及其影响。方法:分析1995年1月～2002年2月间连续2084例正中切口右房-升主动脉体外循环心脏外科手术术前、术中及术后相关因素,观察它们在围手术期肺部并发症中的作用。结果:共有136例肺部并发症(6.5%)。肺部并发症的术前危险因素包括女性(相对危险度OR=1.49)、吸烟(OR=1.64)、慢性阻塞性肺部疾病(OR=2.36),术中危险因素包括应用冷心脏停搏液(OR=1.56),术后危险因素包括需要血管活性药物支持(OR=2.00)、2次开胸(OR=2.08)、主动脉内球囊反搏(OR=2.39)、胸腔积液(OR=2.63)、术后脑血管意外(OR=5.45)、膈神经损伤(OR=8.09)、以及术后肾功能衰竭需用肾透析(OR=12.87)。围手术期肺部并发症不是围手术期死亡的危险因素。结论:心脏外科术后多种围手术期危险因素增加术后肺部并发症的发生,特别是术后脑血管意外、膈神经损伤、以及肾功能衰竭需要肾透析对围手术期肺部并发症的发生影响最为明显。对此类患者需特别注意保护肺功能,以减少并发症的发生。围手术期肺部并发症不是围手术期死亡的危险因素。
