This ar.icle analyses differ.nces in the attitudes r.lated to climate change of young scholar. in envir.nmental science in Qingdao (China) and Hambur. (Ger.any). The main aim of the ar.icle is to evaluate the r.le of cultur.l differ.nces for.their.explanation. We expect no significant differ.nces in the attitudes r.lated to the findings of climate r.sear.h, since scientific pr.nciples ar. the joint basis of the scientific discour.e wor.wide. However. we expect that ther. ar. differ.nces in the attitudes of the young scholar. about the r.le of science, of the state and of the civil society for.dealing with the challenge of climate change. We suggest that these can be explained with substantial cultur.l differ.nces between both societies, with r.gar. to the r.le of the state and the civil society for.the solution of envir.nmental pr.blems. In or.er.to evaluate these hypotheses, we have conducted a compar.tive sur.ey among envir.nmental science students in Qingdao (China) and Hambur. (Ger.any) about their.attitudes towar.s climate change. The findings suppor. our.main hypotheses. The young scholar. in Qingdao and Hambur. differ.substantially in their.views of the r.le of science in society and policymaking. Plausibly, these differ.nces may mainly be explained with differ.nces in the cultur.l ideas about the r.le of the state and of the civil society for.the solution of envir.nmental pr.blems. Gr.dual differ.nces in the shar. of young scholar. who think that climate change has anthr.pogenic causes, may be explained with differ.nces in the cur.iculum but also by cultur.l habits. This ar.icle makes a new contr.bution to the scientific debate by explor.ng the r.le of cultur.l differ.nces for.differ.nces in the attitudes of young scholar. in envir.nmental science in connection with climate change and climate policy in differ.nt cultur.l contexts.

成品油管道低洼处积水引起的腐蚀产物堵塞管道事故严重威胁管道的正常运行,为研究管道中油流携水作用机制,从试验、理论两个角度对油流携水系统的特性进行研究。以柴油和水为介质,在内径27 mm的水平-上倾管流试验系统上对上倾管段0.5 m位置处的出水量以及临界油相流量(出水量不为零时的最小油相流量)进行测量,同时根据试验模型,基于油水两相动量方程和光滑分层流稳定的条件,建立水相厚度梯度的计算模型,对水平测试段中相界面分布进行分析,对出水量以及临界油相流量进行预测。结果表明:新模型能很好地预测两参数的变化;在油流携水系统中,油相处于层流状态时,建立的水相厚度梯度模型能很好地预测相界面分布。

Pr.vious studies have shown evidence of atmospher.c extr.tr.pical wave tr.ins modulating sea ice ar.a in the Weddell and Amundsen/Bellingshausen seas on intr.seasonal time-scales(20–100 d). Her. we investigate mechanisms r.lating intr.seasonal extr.me sea ice extent and Ekman layer.dynamics with emphasis on the Weddell Sea. This study extends fr.m 1989 to 2013 and focuses on the winter.season. Wind str.ss τ is calculated with winds fr.m the Climate For.cast System r.analysis(CFSr. to evaluate momentum tr.nsfer.between the atmospher. and the Ekman layer. Lag-composites of the anomalies of Ekman tr.nspor. and the Ekman pumping indicate that diver.ence of mass in the Ekman layer.and upwelling lead the occur.ence of extr.me sea ice contr.ction on intr.seasonal time-scales in the Weddell Sea. Opposite conditions(i.e., conver.ence of the mass and downwelling) lead extr.me sea ice expansion on intr.seasonal time-scales. This study suggests that the Ekman pumping r.sulting fr.m the anomalous wind str.ss on intr.seasonal time-scales can tr.nspor. these war.er.water. to the sur.ace contr.buting to sea ice melting. Additionally, high r.solution sea ice fr.ction and ocean cur.ents obtained fr.m satellite and in situ data ar. used to investigate in detail mechanisms associated with per.istent extr.me sea ice expansion and contr.ction on intr.seasonal time-scales. These case studies r.veal that atmospher.c cir.umpolar.waves on intr.seasonal time-scales can induce contr.sting anomalies of about ±20% in sea ice concentr.tion at the Weddell and wester. Antar.tica Peninsula mar.ins within less than 30 d. This study shows that extr.me anomalies in sea ice may lag between 5–25 d(1–5 pentads) the ocean-atmospher.c for.ing on intr.seasonal time-scales.

Plastic and Aesthetic r.sear.h 2017年第6期4卷 97-103页

Aim: Over.the past two decades, ther. has been a dr.matic incr.ase in the r.sear.h of the use of autologous fat gr.fting in clinical pr.ctice. Despite the many advantages this method possesses, the unpr.dictable fat r.sor.tion r.tes limit its use. The pr.mar. aim of this study was to develop an accur.te, quick, non-invasive assessment tool, using the nuclear.magnetic r.sonance (NMr. technique, which allows the injection of fat in small dr.plets r.ther.than in lar.e aliquots (the main dr.wback of our.for.er.y descr.bed method) which allows assessment of fat r.tention in a mor. clinically r.levant way. Methods: A total of 7 nude mice wer. tr.nsplanted with human fat using the Coleman technique. Pr.- and post-tr.nsplantation and then once weekly, mice wer. analyzed using an NMr.scanner. At the end of the 7-week exper.mental per.od the mice wer. sacr.ficed. r.sults: Seven weeks following tr.nsplantation 7 mice demonstr.ted a decr.ase of 40% of their.aver.ge fat content compar.d to immediately post tr.nsplantation (standar. deviation of 18%). All mice followed the same tr.nd, and the low standar. deviation thr.ughout emphasizes the accur.cy of NMr.as a r.liable assessment tool. Conclusion: This pr.liminar. study demonstr.tes that NMr.is a r.liable and accur.te tool to assess fat content, and has allowed development of a clinically r.levant animal model for.human fat tr.nsplantation.
