Background Following on from an earlier study published in 2008 about left pulmonary artery(LPA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LPA to right pulmonary artery(RPA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LPA:RPA diameters(PA ratio orPAR)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LPA/RPA diameters,and PAR were compared between survivors and *** value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic(ROC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** PAR for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean PAR for non-survivors was not affected by surgical *** of survivors were:LPA≥2 mm(n=52 of 54;mean PAR=0.866±0.146)and RPA≥3mm(n=46 of 54;mean PAR=0.857±0.152).Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean *** curve cut-off for PAR was *** with high PAR(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low PAR(<0.762)(p=0.0244 and p=0.0485,respectively)and subjects with high PAR stabilized significantly earlier than subjects with low PAR(1.71±0.68 days vs 3.20±0.87 days)(p<0.0001).Conclusions PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

Study of the Effect of Acetic Acid and Phosphate on Copper Corrosion by Immersion Tests

引用

Materials Sciences and Applications 2024年第1期15卷 15-23页

作者： Yuna Yamaguchi Kaho Sugiura Toyohiro Arima Fuka Takahashi Itaru Ikeda Yutaka yamada Osamu Sakurada Department of Chemistry and Biomolecular Science Faculty of Engineering Gifu University Gifu Japan Dai-Dan Co. Ltd. Saitama Japan Daiwa Techno Co. Ltd. Gifu Japan

It was reported that hemispheric corrosion occurred in copper tubes in an acetic acid environment. When hemispheric corrosion occurred, corrosion could easily progress if water then flowed into the copper pipe, and countermeasures were needed. Therefore, we studied the copper corrosion caused by acetic acid. The present work investigated the relationship between the corrosion form of copper and acetic acid concentration using phosphorous-deoxidized copper, and reported that hemispherical corrosion was observed at acetic acid concentrations of 0.01 to 1 vol.% (0.002 to 0.2 mol·L-1) in the immersion test. In this study, the effects of acetic acid and phosphate on copper corrosion were examined using oxygen-free copper in immersion tests. The results suggested that different concentrations of phosphate in acetic acid solutions and the presence or absence of acetic acid and phosphate affected the corrosion of copper, resulting in different corrosion forms and corrosion progress.

本文主要讨论上古汉语的否定词“不”与“弗”,重在利用战国秦汉时期的出土文献和传世文献,揭示上古各个时期的“不”与“弗”的分合演变:在先秦时期,“弗”是“不”加前置宾语代词“之”的合音词,然而在两汉时期,代词宾语前置现象减少,代词宾语“之”也逐渐式微,同时“不”“弗”的功能接近,导致“弗”字的语源渐渐被忘却,“弗”不再被视为“不+之”的合音,而是成为一个带有强调语气的单纯否定词。本文还对“不”获得分勿切一读的原因提出了自己的看法。
