Behavioral interventions to reduce demand for threatened freshwater turtles as pets

open access: yesConservation Biology, EarlyView.
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

介孔掺硫活性炭活化过硫酸盐降解曙红Y废水的研究

open access: yesGongye shui chuli, 2023
在不同活化温度下制备了介孔掺硫活性炭(ACS-X),通过扫描电镜(SEM)、元素分析(EA)、N2-等温吸脱附、X射线光电子能谱(XPS)等手段对其进行表征。通过建立掺硫活性炭活化过二硫酸盐(PS)降解曙红Y(EY)体系,探究了孔结构性质对活性炭吸附性能和催化性能的影响。结果表明,ACS-X的孔结构是影响活性炭吸附性能的主要因素,而活性炭的催化性能由孔结构性质和含硫官能团的存在形式及原子分数共同影响。还考察了ACS-X投加量、PS浓度、EY浓度、溶液初始pH等因素对EY废水降解效果的影响 ...

污泥基活性炭深度处理垃圾渗滤液的研究

open access: yesGongye shui chuli, 2014
以市政污泥为主要原料,掺加少量玉米秸秆,采用化学活化与高温热解的方式制取污泥基活性炭,通过对活性炭表征分析得出秸秆最佳质量掺合比为10%,对垃圾渗滤液尾液动态吸附结果表明污泥基活性炭深度处理效果良好。物料平衡与能量衡算结果显示:污泥热解制备活性炭过程中产生的能量大于外界加热所需能量,理论上可在不消耗外界能量下进行规模化生产。

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Cantonese (Dis)investment by Cross‐Border Postgraduates in Hong Kong: Negotiating Competing Capitals and Multiple Identities Among Neoliberal Subjects

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT One key strategy that local universities and the government of Hong Kong have adopted in recent years is attracting more students from Chinese Mainland to study at Hong Kong's higher education institutions and contribute to society after graduation.

全球火山活动时空分布特征及其对强震活动趋势的指示

open access: yesDizhen xuebao
基于史密森学会火山目录分析了全球火山活动的时空特征,并结合中国地震台网目录讨论了火山活动对全球和中国大陆强震活动趋势的指示意义。结果显示:① 全球火山活动表现出较为显著的百年周期特征,且百年周期内火山活动和M≥8.0大震之间存在着频次准同步和能量互补现象;② 中国大陆1955年前后强震活动状态的变化可能与同期全球火山活动状态变化密切相关,且二者可能受控于百年周期内地球内部能量积累与释放的状态变化;③ 2022年汤加火山的剧烈喷发意味着地球内部能量仍在持续释放 ...

AI foundation models in plant biology

open access: yesNew Phytologist, EarlyView.
Foundation models decode genomes, engineer proteins, phenotype crops, and drive AI agents across plant biology. This figure was created in BioRender (BioRender.com/xcmmkel). Summary Rapid technological progress has enabled plant biologists to accumulate unprecedented volumes of multi‐scale, multi‐modal data, yet this abundance of data has intensified ...

Revitalizing Traditional Tank Systems: Case Study Insights From Sri Lanka's Village Tank Cascade Systems for Climate Resilience and Water Governance

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Village tank cascade systems (VTCS) are a long‐established form of water management in Sri Lanka's dry zone. However, their role in groundwater recharge, climate adaptation, and water governance remains insufficiently recognized in policy and planning.

臭氧氧化与生物法联合处理苯酚和苯胺废水研究

open access: yesGongye shui chuli, 2015
采用臭氧氧化、活性污泥法以及臭氧氧化与活性污泥联用法分别处理苯酚及苯胺废水。结果表明,这3种方法都能去除废水中的有机物,但单独臭氧氧化主要将苯酚和苯胺转化成中间产物,并不能将它们彻底矿化成二氧化碳和水。未经臭氧氧化直接进行活性污泥处理,1 h后苯酚和苯胺的去除率达到60%左右。臭氧氧化1 h与SBR活性污泥法曝气1 h对苯酚和苯胺的去除率可达95%以上。

Polyphenol oxidase depletion in Nicotiana benthamiana enhances recombinant protein purification and preserves native protein integrity

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1283-1293, August 2026.
Polyphenol oxidases (PPOs) depletion preserves endogenous proteins at their predicted molecular weights and enhances detectable enzymatic activities. (a) Less RbcL crosslinking in ppo mutant of Nicotiana benthamiana. Leaf extracts were incubated for 1 h, separated on protein gels, stained with Coomassie or analyzed by Western blot with the anti‐RbcL ...
