Wildlife Letters, Volume 3, Issue 3, Page 109-117, September 2025.We found that the Asian Openbill primarily roosted near waterbodies and frequently used farmland habitats, with significantly higher populations observed during the breeding season. Farmland and wetland areas exhibited a positive effect on the species' habitat use.

Dualization and Social Policies: A Conceptual and Analytical Framework
Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT This thematic review offers a conceptual and analytical framework to assess, identify, and explain the processes of dualization in labor markets and social protection systems in 21st‐century welfare states. After a brief historical examination of the concept's origins, we review the primary definitions, theories, and typologies developed to ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 470-477, April 2025.ABSTRACT Objective To evaluate the presence and levels of cytomegalovirus (CMV) cell‐free DNA (cfDNA) fragments in women pregnant with a fetus with symptomatic congenital CMV (cCMV). Methods The study comprised nine women whose fetuses were diagnosed with cCMV between June 2019 and July 2024 at 20 + 4 to 34 + 1 weeks' gestation (n = 8) or neonatally (n

Dianci bileiqi, 2016 输电线路覆冰是我国常见的自然灾害,危害极大,而现有融冰方法均存在各自的局限性。对此,提出一种基于串联谐振原理的工频谐振融冰方法,并分析了此方法的融冰原理及融冰接线方式;计算了典型导线的工频谐振融冰电流并同直流融冰法作了对比分析;定量分析了融冰中出现的谐振电压并提出电容器组串联均压和改变融冰接线方式降压的办法;最后简要介绍工频谐振融冰装置关键设备的构成。研究结果表明:与直流融冰相比,本方法融冰效率更高;通过控制融冰线路长度和融冰源接入方式可使融冰谐振电压处于线路绝缘水平范围内;融冰电源容量小,构造简单 ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 303-310, March 2025.ABSTRACT Objective Globally, one in four pregnant women is classified as overweight or obese, based on their prepregnancy body mass index (BMI). Obese pregnant women are at increased risk of adverse pregnancy outcomes and long‐term cardiovascular disease that occurs earlier in life.

Gaoya dianqi, 2019 架空导线作为输送电力的载体,其交流电阻对导线输送容量及线路损耗有直接影响。文中对巴雷特（Barrett）提出的关于导线交流电阻计算的等效电路模型做了改进并称之为磁特性分析法,计及复合磁导率随温度的变化和线芯导电性,考虑不同层铝绞线之间的温差,以及采用与磁通量计算区域边界吻合的圆弧形电流微元。分别以该法、摩根法（Morgan）和日本JCS 0374算法对一种铝包钢芯铝绞线计算了交直流电阻比,结果显示磁特性分析法计算值相对另外两种方法偏小,理论分析认为该法计算结果更为接近实际。

High Irradiance Laser Ionization Time-of-Flight Mass Spectrometry for Direct Speciation Analysis of Iron Oxides and Cobalt Oxides [PDF]
, 2010 在人们的传统观念看来，对于待考察样品中元素的分析仅限于定性，半定量和定量。然而，随着科学技术日新月异的进步，人们的认识也在不断地提高，越来越多的科学工作者意识到对于许多元素而言，仅仅测定它们各自的总含量对于样品评估来说是远远不够的，甚至在某些情况下还会引起一些危害性的错误结论。关于元素砷的测定就是一个最好的例证：在很多海鲜中，元素砷主要是以无毒的有机砷化合物的形式存在；而无机砷相对则是带有剧毒性的，并且在某种程度上取决于砷的化合价。由此可见，元素的化学形态直接决定着它们的很多性质，例如毒性，生物 ...

Challenges in assessing the effects of environmental governance systems on conservation outcomes
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Effective governance is crucial for the success of conservation projects aimed at protecting wildlife populations and supporting human well‐being. However, few large‐scale, comprehensive syntheses have been conducted on the effects of different environmental governance types on conservation outcomes (i.e., biological and ecological ...
