The overuse of antibiotics and antitumor drugs has resulted in more and more extensive pollution of water bodies with organic drugs,causing detrimental ecological effects,which have attracted attention towards effective and sustainable methods for antibiotics and antitumor drug ***,the hybrid nanomaterial(g-C_(3)N_(4)@Fe/Pd)was synthesized and used to remove a kind of both an antibiotic and antitumor drug named mitoxantrone(MTX)with 92.0%removal efficiency,and the MTX removal capacity is 450 mg/*** exposing to the hybrid material the MTX aqueous solution changed color from dark blue to lighter progressively,and LC-UV results of residual solutions showthat a newpeak at 3.0min(MTX:13.2min)after removal by g-C_(3)N_(4)@Fe/Pd appears,with the simultaneous detection of intermediate products indicating that g-C_(3)N_(4)@Fe/Pd indeed degrades *** mass spectrometric analysis suggests that the nuclear mass ratio decreased from 445.2(M+1H)to 126.0(M+1H),169.1(M+1H),239.2(M+1H),267.3(M+1H),285.2(M+1H),371.4(M+1H)and 415.2(M+1H),and the maximum proportion(5.63%)substance of all degradation products(126.0(M+1H))is 40-100 times less toxic than MTX.A mechanism for the removal and degradation of mitoxantrone was ***,actual water experiments confirmed that the maximum removal capacity of MTX by g-C_(3)N_(4)@Fe/Pd is up to 492.4 mg/g(0.02 g/L,10 ppm).

以重庆中梁山为例,通过野外埋放标准溶蚀试片、土壤CO2收集装置和进行亮蓝染色示踪试验,测试不同土地利用方式下不同土层碳酸盐岩溶蚀速率、土壤CO2浓度、土壤溶解性有机碳(DOC)含量及土壤含水量、土壤pH值和孔隙度等性质,探讨不同土地... 详细信息

以重庆中梁山为例,通过野外埋放标准溶蚀试片、土壤CO2收集装置和进行亮蓝染色示踪试验,测试不同土地利用方式下不同土层碳酸盐岩溶蚀速率、土壤CO2浓度、土壤溶解性有机碳(DOC)含量及土壤含水量、土壤pH值和孔隙度等性质,探讨不同土地利用方式土下溶蚀速率差异及其影响因素。结果表明不同土地利用方式对土壤理化性质产生影响,形成特定的岩溶微环境,进而影响土下不同层次的岩溶作用:土壤CO2浓度是影响林地和草地旱季土下溶蚀速率的重要驱动力;土壤含水量和供水能力是影响旱季不同土地利用方式溶蚀速率的关键因素;菜地产生的酸性物质较多,土壤pH值最低,其平均溶蚀速率高于林地;土壤DOC随水下渗迁移性强,是林地土下50 cm处溶蚀速率高于土下20 cm处的原因之一。该文为西南岩溶区土下岩溶机理、岩溶碳汇提供理论依据和数据参考。

本研究旨在探讨共同富裕背景下职业教育中产教融合育人模式的有效实施,以提高中等职业教育的教学质量和培养高质量职业人才。在方法方面,本文采用了实地深度问卷调查的方式,对政府、企业、中职学校和学生4个主体进行调查,并对问卷调查结果进行分析和比较。结果显示,产教融合不足、产教融合权责不明,导致人才培养效果大打折扣。因此,我们需要采用具体化、责任化、一体化的方式推进产教融合,并在政府主导下逐步强化产教融合共同体的作用以及逐步推进产教融合共同体的建设。这对于提高中等职业教育的教学质量、培养符合市场需求的高质量职业人才具有非常重要的意义。

文章以耕地为对照,分析不同石漠化治理措施(花椒林和次生林)对土壤0~20 cm土层有机碳(SOC)、颗粒有机碳(POC)、矿物结合有机碳(MOC)和团聚体有机碳的影响,探讨POC、 MOC与SOC、团聚体有机碳的关系。结果表明:与耕地相比,花椒林和次生林均不同程度提高SOC、POC、MOC和团聚体有机碳含量。0~10 cm土层次生林SOC含量和各粒径团聚体有机碳含量均显著高于耕地和花椒林,在10~20 cm土层无显著差异;0~20 cm土层花椒林和次生林土壤POC含量显著高于耕地,MOC无显著差异。POC/SOC范围为20.38%~45.27%,花椒林和次生林显著高于耕地。相反,MOC/SOC为耕地显著高于花椒林和次生林。退耕为花椒林和次生林后,SOC含量的增加主要以POC含量增加为主。次生林和花椒林>2 mm粒径对SOC贡献率显著高于耕地,但0.25~2 mm粒径、0.053~0.25 mm粒径和花椒林>耕地。退耕恢复为花椒林和次生林后,SOC、POC和MOC增加量与团聚体有机碳增加量显著相关,其以次生林的相关性较强。石漠化治理措施改变SOC物理组分及其组成以及它们之间的关系,从而促进有机碳的积累。

The long-term consequences of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection,known as the post-acute sequelae of COVID-19(PASC),have been a growing concern.A significant proportion of COVID-19 patients experience persistent health issues even six to twelve months after recovering from acute infection[1],[2],[3],[4].Therefore,understanding the immune reconstitution process and identifying the molecular and cellular mechanisms underlying PASC is crucial.
