The stockholm Convention on Persistent Organic Pollutants(POPs)is a legally binding instrument for 186 Parties(status:April 2023).Accordingly,among other responsibilities,countries are obliged to report the production,import,or export of the POPs listed in Annexes A,B,or C;provide information to registers;maintain inventories;and monitor the presence of POPs in the *** the broader context of international chemicals and waste management,producer responsibilities,harmonized reporting,and compliance with national and international regulations,Ecuador has addressed the newly listed group of perfluorinated alkyl substances(PFAs)in its national implementation plan and sent selected products from its national market for PFAs *** products analyzed came from the initially listed fields of specific exemptions and acceptable purposes,including:fire-fighting foams;photographic aids;greasers/degreasers;various kinds of paper/packaging;textiles;and leather,coatings,cleaners,metal plating,and *** results showed that the three PFAs presently listed in the stockholm Convention could be quantified in only a few samples;additional PFAs,not yet listed in the Convention also had low detection *** the number of samples was limited,the samples covered a large spectrum of sample matrices,making it possible to conclude that—once these products become waste and are regulated under the Basel Convention—they would not constitute a disposal ***,verification of the presence of PFAs in products on the market is expected to pose an analytical challenge for both,developed and developing countries.

In recent years, multimode fiber(MMF) has become an important tool for high-resolution endoscopic imaging in narrow channels(e.g., in the brain via needles or inside blood vessels) due to its high mode density and fine diameter, typically stacle to widespread deployment in applications is that realistic perturbations, including bending, twisting and changes in temperature, cause unacceptable image degradation.

This paper presents a new computational method for forward uncertainty quantification(UQ)analyses on large-scale structural systems in the presence of arbitrary and dependent random *** method consists of a generalized polynomial chaos expansion(GPCE)for statistical moment and reliability analyses associated with the stochastic output and a static reanalysis method to generate the input-output data *** the reanalysis,we employ substructuring for a structure to isolate its local regions that vary due to random *** allows for avoiding repeated computations of invariant substructures while generating the input-output data *** substructuring with static condensation further improves the computational efficiency of the reanalysis without losing ***,the GPCE with the static reanalysis method can achieve significant computational saving,thus mitigating the curse of dimensionality to some degree for UQ under high-dimensional *** numerical results obtained from a simple structure indicate that the proposed method for UQ produces accurate solutions more efficiently than the GPCE using full finite element analyses(FEAs).We also demonstrate the efficiency and scalability of the proposed method by executing UQ for a large-scale wing-box structure under ten-dimensional(all-dependent)random inputs.

目的对比分析射频消融术与肝切除术两种治疗方式在胃肠间质瘤(GIsT)肝转移中的临床疗效。方法采用回顾性队列研究的方法,收集2018年1月-2022年12月于中国人民解放军总医院第一医学中心接受治疗的46例GIsT肝转移患者的病例资料。按治疗方式不同分为射频消融组(n=20)和肝切除组(n=26)。对比两组患者的短期疗效及长期预后,短期疗效通过术中出血量、手术时间、住院时间、住院费用进行判断,长期疗效通过无进展生存期和总体生存期进行判断。正态分布的计量资料以均数±标准差(x±s)表示,组间比较采用t检验。非正态分布的计量资料以M(Q1,Q3)表示,组间比较采用Wilcoxon秩和检验。计数资料组间比较采用χ^(2)检验,并采用Kaplan-Meier曲线比较两组患者的长期预后。结果射频消融组患者术中出血量、手术时间、术后住院时间、住院费用分别为5(3,5)mL、60(55,60)min、4.0(3.0,4.0)d、4.6(3.8,5.3)万;肝切除组患者分别为100(50,275)mL、180(155,215)min、7.0(4.5,9.5)d、8.6(6.1,10.8)万,两组相比差异具有统计学意义(P0.05)。结论肝切除术和射频消融术均可作为GIsT肝转移的治疗选择,两者长期疗效相当。肝切除术在肿瘤局部控制率方面比射频消融术更具有明显优势,射频消融具有并发症少、恢复快、住院时间短的优势。

以氯化胆碱和乙二醇混合液为低共熔溶剂,不使用其他添加剂,电化学沉积无枝晶Zn/Au合金。在不同的Zn(Ⅱ)浓度下,采用恒电位电沉积法在相对较低的Zn电沉积过电位下进行电沉积。通过循环伏安法(CV)和计时安培法(CA)揭示Zn电沉积的电化学机理。采用扫描电子显微镜和X射线衍射分析(XRd)对沉积层的形貌和结构进行表征,并用能谱仪对沉积层进行元素分析。CV结果表明,Zn的电沉积始于Zn欠电位沉积区,并一直持续到Zn过电位沉积(OPd)区。随着Zn(Ⅱ)浓度的增加,Zn/Zn(Ⅱ)电偶的沉积电位向更高的正值偏移。CA分析表明,在Zn的OPd区开始三维渐进形核,随后形成三维生长。形貌分析表明,电沉积始于致密Zn岛的形成,随后形成无枝晶Zn/Au合金。XRd分析表明,其物相为金属Zn、立方AuZn3和Au Zn金属间化合物。

目的:探讨多模式CT对急性前循环缺血性脑卒中患者侧支循环及临床预后的评估价值。方法:纳入50例临床确诊的急性前循环脑卒中患者,均于治疗前行多时相CT血管成像(mCTA)和CT灌注成像(CTP)检查。收集患者核心梗死区、缺血半暗带及健侧对照区CTP检查参数,依改良Rankin评分(mRs评分)分为预后良好和预后不良组,比较两组CTP灌注参数的差异;用Monen评分法对mCTA进行侧支评估,比较良好侧支组与不良侧支组90d美国国立卫生研究院卒中量表(NHIss)评分、mRs评分的差异。结果:与不良预后组对比,良好预后组可观察到较高的rCBV;mCTA侧支评估良好组与不良组对比,90d时NHIss、mRs评分较低,神经功能缺损较轻,预后较好。结论:多模式CT可较好评估脑卒中患者侧支循环情况,对神经功能缺损及临床预后有一定的指示作用。
