Understanding the Impact of Institutions on Climate‐Adaptive Policy Designs: A Study of Collective Action Inference in Urban Water Systems

open access: yesPolicy Studies Journal, Volume 53, Issue 3, Page 637-653, August 2025.
ABSTRACT Feedback is ubiquitous in complex systems and critical to the process of designing public policies to solve problems such as climate adaptation. However, well‐known cognitive and institutional constraints can impact information feedback processes, limiting a system's ability to incorporate feedback into policy designs.

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.

Chronotopes of Transnational Literacies: How Youth Live and Imagine Social Worlds in their Digital Media Practices

open access: yesReading Research Quarterly, Volume 60, Issue 1, January/February/March 2025.
In this study, we examine how social connectedness is semiotically constructed through time‐space framing in two youths’ transnational communication. The youths’ narratives show how they positioned themselves in proximity with their peers within particular contexts that supported their actions and emotions, or ways of thinking and feeling.

自动供排水蒸发皿

open access: yes, 2010
本实用新型涉及一种自动供排水蒸发皿,该蒸发皿为夹层,在皿体上口为内直外斜刀口,斜面为45°,斜面上设有出气口,蒸发皿内侧下方设有进气出水口,在出水口一侧的皿体底部固定溢流管,溢流管的另一端与溢流桶对接。通过将水置于皿内的夹层中,皿内水深小于20mm时,自动补水,使水深保持为20mm;下大雨时,皿内的溢流管排出超过20mm的水至溢流桶内,保持皿内水深20mm,内外溅水一致,可增加站际间蒸发资料的可比性。从而解决了目前采用的蒸发皿内水深不稳定 ...

厌氧与缺氧/好氧交替式SBR处理印染废水

open access: yesGongye shui chuli, 2021
开展了厌氧与缺氧/好氧交替式SBR处理实际印染废水的小试研究。厌氧SBR处理印染废水的COD平均去除率为75%,平均出水COD为237 mg/L。缺氧/好氧交替式SBR采用分段进水和外加碳源的方式处理厌氧SBR出水,两段进水分配比为800 mL:200 mL时,处理效果较佳,仅因反硝化碳源不足导致出水总氮未满足《纺织染整工业水污染物排放标准》(GB 4278-2012)的直接排放标准;外加葡萄糖的实际与理论投加量之比为3时,处理效果最佳,出水平均COD为79 mg/L、氨氮为0.4 mg/L、总氮为13.

车载移动式钻井废水处理工艺及装置研究

open access: yesGongye shui chuli, 2007
针对目前油气田产生的钻井废水具有面广、量大、成分复杂、水质差别大,而现有的污水处理工艺处理费用高、效率低下、且其外排的水质已不能满足相关排放要求的特点,研究出一套适合于钻井废水处理的移动式工艺流程,并对工艺的装置进行优化。根据对不同水质(浅井、中深井、深井)的处理、调查,设计出适合于四川地区的移动式污水处理工艺。整套工艺以搅拌、混凝、沉降、氧化为主,通过对废水的预处理使出水水质除COD外其他污染指标都可以达到相关排放标准,然后再通过氧化罐进一步降低COD,最终可使之达到相关排放要求。
