Placental biomarker and fetoplacental Doppler abnormalities are strongly associated with placental pathology in pregnancies with small‐for‐gestational‐age fetus: prospective study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 749-760, June 2025.
ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

Effect of uneven tolerance to human disturbance on dominance interactions of top predators

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Anthropogenic activities may alter felid assemblage structure, facilitating the persistence of tolerant species (commonly mesopredators), excluding ecologically demanding ones (top predators) and, consequently, changing coexistence rules. We aimed to determine how human activities influence intraguild relationships among top predators and ...

吐哈温米油田水质控制技术的研究与应用

open access: yesGongye shui chuli, 2012
在吐哈温米油田回注污水处理系统的运行过程中发现,处理后的回注污水水质不稳定,缺乏有效的控制手段。在吐哈油田回注污水系统流程中选取6 个取样点作为节点,分别对6 个节点进行取样监控,并对水源pH、总铁、含油量、溶解氧等指标进行节点控制。实践结果表明:采用水质节点控制技术后,系统能按方案运行且水质有大幅提高,较好地解决了吐哈温米油田水质不稳定的问题,该技术具有较高的推广价值。
