Two decades of changes in the global network of illegal wildlife trade
Abstract Understanding how illegal wildlife trade (IWT) has changed over time is fundamental for biodiversity conservation; however, knowledge of the network remains limited. We used TRAFFIC's IWT dataset, legal trade data from the CITES legal wildlife trade database as a benchmark, and network analysis to identify changes in IWT from 2000 to 2022. The

气泡普遍存在于火山熔岩脱气、废水处理和许多其他工业过程中。当气泡相互接触时,不可避免地会发生气泡聚并。Paulsen等人实验研究了外部流体对液滴和气泡聚并的影响,用无量纲数μ/(ργA)~(1/2).给出了外部流体粘度作用的时间。Shaw等人研究了气泡在气-水界面的聚并,描述了水下气泡颈部和表面桥的演化规律。Chen等人通过模拟方法研究了液体粘度、液体密度和表面张力对微泡聚并的影响。气泡聚并的研究大多在毫米量级。由于这一过程发生的时间较短,因此更难在微观尺度上进行捕捉和观察 ...

目的检测肺癌患者血D-二聚体的改变,了解它与肿瘤发展、扩散、预后及疗效的关系。方法检测肺癌患者359例,其中305例为带瘤患者,54例术后2a无复发、转移,分析其血D-二聚体水平在不同分期、病理类型及治疗过程中的异常改变。结果305例肺癌患者的血D-二聚体水平显著高于正常对照组和54例术后无复发、转移患者,且随着肿瘤发展和扩散、转移明显升高;23例小细胞肺癌患者临床治愈时的血D-二聚体水平明显低于疗前和复发时;不同病理类型肺癌患者血D-二聚体水平在局限期和扩散期无明显差异。结论肺癌患者早期就有血D ...

This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

目的探讨足月孕妇血浆D-二聚体的正常值水平以及统计分布,为妇产科临床诊疗提供依据。方法收集足月待产孕妇的D-二聚体数据(剔除有死胎、HELLP综合征、妊娠并发DIC等不良妊娠病例和妊娠合并血液系统疾病)共4000例,应用软件SPSS 17.0和Origin75进行统计学分析。结果足月产妇的D-二聚体水平呈明显的偏态分布,95%的孕妇D-二聚体水平≤5.77μg/ml;不同年龄组、不同合并症组孕妇血浆D-二聚体水平不全相同,低龄孕妇组与适龄产妇组血浆D-二聚体水平差异有统计学意义 ...

ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
