2020年初,新型冠状病毒(SARS-CoV2)席卷全球,该病毒引发的肺炎命名为新型冠状病毒肺炎(Corona Virus Disease 2019),各个国家疫情期间常规临床医疗诊治工作遭受极大冲击,传统"面对面"诊治医疗模式在新冠疫情期间实施有一定的难度,对糖尿病足溃疡的防治目标应从疫情前的尽量提高足溃疡愈合率、缩短愈合时间转变为预防足溃疡发生、阻止足溃疡感染加重、足溃疡恶化并尽量避免住院。故本文对新型冠状病毒肺炎疫情期间糖尿病足溃疡患者诊治模式进行综述,对类似突发医疗事件期间糖尿病足溃疡的诊治策略提供依据。

微气泡气浮技术在低能耗下对含油污水的高效处理是目前的研究热点。利用气泡雾化喷嘴作为微气泡发生器,搭建了低能耗微气泡射流气浮处理含油污水的实验系统,系统研究了气液质量流量比(ALR)和工作压力(p)对微气泡群尺度分布特征和除油效果的影响,并计算了气泡雾化喷嘴的能耗。实验结果表明,利用气泡雾化喷嘴形成液下射流可以产生大量微气泡,其中尺度小于150μm的气泡数量占比在55%以上、小于600μm的气泡数量占比在98%以上;随着ALR的增加,微气泡数量整体呈现先增后减的变化趋势,最佳ALR=0.15;当p=0.2 MPa、ALR=0.15时,微气泡群的索特尔平均直径可降低至238μm,出水含油质量浓度为29.73 mg/L,微气泡射流气浮装置处理1 kg含油污水时能耗仅为6.53×10^(-4) kW·h,较溶气气浮能耗降低35%以上。

When Wilbur Schramm attempted to connect the established departments of journalism and speech into a new discipline called"communication studies",his invitation was criticized as being without a core set of theories and methodologies and the field of"communication studies"was viewed as too undefined,all-inclusive,and even chaotic to justify its standing as a discipline at all[1].Today,most of these doubts and critics disappeared when we witness the 80-year fruitful development of the"communication studies".Schramm titled his seminal book"Men&Women,Messages and Media"to summarize and highlight the necessity of including multiple disciplines to participate the"communication studies"[2].

Eutrophication caused by inputs of excess nitrogen(N) has become a serious environmental problem in Hangzhou Bay(China),but the sources of this nitrogen are not well *** this study,the August 2019 distributions of salinity,nutrients [nitrate(NO_3~-),nitrite,ammonium,and phosphate],and the stable isotopic composition of NO_3~-(δ~(15)N and δ~(18)O) were used to investigate sources of dissolved inorganic nitrogen(DIN) to Hangzhou B *** distributions of nitrate,salinity,and nitrate δ~(18)O indicate that the Qiantang River,the Changjiang River,and nearshore coastal waters may all contribute nitrate to the *** on the isotopic compositions of nitrate in these potential source waters and conservative mixing of nitrate in our study area,we suggest that the NO_3~- in Hangzhou B ay was likely derived mainly from soils,synthetic N fertilizer,and manure and ***-member modeling indicates that in the upper half of the bay,the Qiantang River was a very important DIN source,possibly contributing more than 50% of DIN in the bay head *** the lower half of the bay,DIN was sourced mainly from strongly intruding coastal *** coming directly from the Changjiang River made a relatively small contribution to Hangzhou Bay DIN in August 2019.
