针对麦田土壤镉(Cd)、砷(As)和铅(Pb)复合污染问题,采用田间小区试验,于拔节期、孕穗期和灌浆初期对小麦进行叶面单独和混合喷施Zn(0.2%ZnSO_(4))、Mg(0.4%MgSO_(4))和Mn(0.2%MnSO_(4))处理,以期探究叶面调理剂对小麦籽粒Cd、As和Pb累积的阻控效应,最终筛选出适用于北方重金属复合污染区有效阻控小麦籽粒中Cd、As和Pb累积的叶面调理剂.结果表明,与对照相比,叶面喷施Zn+Mg+Mn复配溶液能够显著降低小麦籽粒中Cd、As和Pb含量,降幅分别为18.96%、23.87%和51.31%,TF籽粒/秸秆分别降低了14.62%、27.73%和47.70%,该叶面调理剂能够通过抑制Cd、As和Pb从小麦茎叶到籽粒的转运进而降低其在籽粒的累积;研究还发现,对照的籽粒中Cd和As主要分布在中心胚乳(34.08%~37.08%),而Pb主要分布在果皮和种皮(27.78%).喷施Zn+Mg+Mn复配溶液可显著降低Cd和As在糊粉层含量,分别比CK降低81.10%和82.24%,而Pb除果皮和种皮、中心胚乳外,各层次Pb含量均显著降低(降幅为42.85%~91.15%),各层次面粉只有糊粉层(P2)重金属含量与Zn含量呈显著负相关.综上所述,对于北方石灰性土壤Cd、As和Pb中度复合污染农田,于小麦拔节期、孕穗期和灌浆初期各喷施一次Zn+Mg+Mn复配的叶面调理剂,可有效阻控Cd、As和Pb在小麦籽粒尤其是糊粉层的累积.在此基础上,可通过去除麦麸来进一步降低重金属尤其是Cd的污染,保证小麦安全生产和粮食安全.

[背景]根据《职业病分类和目录》,布鲁氏菌病是法定职业性传染病之一,在职业人群中时有发生。[目的]比较13例布鲁氏菌病患者省、市两级工伤劳动能力鉴定的过程和鉴定结果,分析总结劳动能力鉴定管理部门和劳动能力鉴定专家在布鲁氏菌病等职业病门科劳动能力鉴定实际工作中存在的偏差,研究并提出改进完善建议。[方法]对13例布鲁氏菌病患者职业接触史、临床诊断、职业病诊断分期、劳动能力鉴定依据的客观检查结果及劳动能力鉴定结论进行梳理分析,对比研究市级初次鉴定结论和省级最终鉴定结论不一致的原因。[结果] 13例布鲁氏菌病患者认定工伤后全部申请了市级劳动能力鉴定,11例没有获得伤残等级,2例评为10级伤残。4例没有评上伤残等级的患者申请了省级劳动能力鉴定,2例维持了原鉴定结论,2例更改了鉴定结论,分别评为九级伤残和十级伤残。在回顾过往鉴定结果时发现,职业性布鲁氏菌病工伤劳动能力结果评定为九级伤残或十级伤残的案例,在石家庄市初级劳动能力鉴定和河北省再次劳动能力鉴定工作中尚属首次。由此总结的主要经验是职业病所致的靶器官损伤和(或)功能障碍的严重程度是工伤劳动能力鉴定的直接依据,职业性布鲁氏菌病工伤劳动能力鉴定时应该根据每一例评残对象,逐个确定相关的靶器官损伤和功能障碍程度,进行综合判定后做出客观、科学的伤残等级评定结论。[结论]该鉴定对河北省乃至全国的职业性布鲁氏菌病的工伤劳动能力鉴定应该会有指导和引领作用。GB/T16180-2014《劳动能力鉴定职工工伤与职业病致残等级》(简称GB/T16180-2014)标准中职业病门科的相关条款存在滞后性。当前情况下劳动能力鉴定时专家除了在标准认真查找和职业病伤情能够直接对应的条款,还应该针对条款中没有涵盖的病患,结合职业病的特点,科学、准确、灵活应用该标准的单项条款和附录中的补充条款,这样才能做出公平、公正、专业的鉴定结论。

大力发展光伏等可再生能源是我国实现“双碳”目标的重要途径,而光伏高比例接入配电网后随之带来一系列问题。以含高比例光伏配电网为研究对象,提出了计及用户侧需求响应的混合储能优化配置方法。针对负荷和光伏出力的双重不确定性,提出了基于预测误差概率分布的不确定性场景确定方法。考虑系统不确定性,统筹运行阶段用户侧需求响应调控措施以及潮流约束,提出了储能配置的3层优化模型。针对优化模型提出了相应的分解方法,以及基于列和约束生成算法的求解实施流程。通过在IEEE-33节点测试系统中的应用,使得系统可平移负荷峰值下降了10%,节点电压维持在合理范围,并在指导储能配置等方面具备显著的应用效果。通过分析光伏比例灵敏性可知,不含光伏情况下的储能总容量相比100%光伏比例场景增加了90%。

目的探讨贝母素甲(PME)对慢性阻塞性肺疾病(COPD)小鼠的作用和相关机制。方法将80只小鼠随机分为4组(每组20只):对照组、PME组、COPD组和治疗组。使用脂多糖联合烟雾诱导小鼠COPD动物模型。通过组织病理学、超微结构、小鼠肺组织湿/干重比值分析PME对COPD模型鼠结构的影响;ELISA和Western blotting分析PME对肺组织中炎症因子肿瘤坏死因子(TNF)-α、白细胞介素(IL)-6和IL-1β表达的影响;二氢乙锭(DHE)染色和Western blotting分析PME对肺组织中氧化应激反应的影响;Western blotting分析PME对核因子κB(NF-κB)通路以及核因子2相关因子2(Nrf2)通路相关蛋白表达的影响。结果与COPD组相比,PME治疗可明显减轻小鼠肺组织的损伤和减少炎症细胞数量,降低肺组织湿/干重比。与对照组相比,COPD组小鼠的肺泡灌洗液中TNF-α、IL-6及IL-1β水平明显增加,经PME治疗后小鼠肺泡灌洗液中TNF-α、IL-6及IL-1β水平明显降低。另外,与对照组相比,COPD组小鼠肺组织中TNF-α和IL-1β水平显著升高,经PME治疗后小鼠肺组织中TNF-α和IL-1β蛋白水平明显下降。免疫组织化学和Western blotting实验显示,与对照组相比,COPD组SOD2水平明显降低,而PME治疗后能够提高超氧化物歧化酶(SOD)蛋白水平。对肺组织丙二醛(MDA)含量分析发现,与COPD组比较,PME治疗后明显抑制COPD小鼠肺组织中MDA的产生。Western blotting结果显示,PME治疗后能够阻止肺组织中的NF-κB抑制蛋白(IκBα)磷酸化以及NF-κB p65向细胞核转移,PME处理后的小鼠肺组织中Nrf2及其主要下游靶点血红素加氧酶1(HO-1)的表达明显升高。结论PME能够抑制COPD小鼠体内的炎症和氧化应激反应,改善脂多糖联合烟雾诱导肺组织损伤,其机制可能与激活Nrf2通路和抑制NF-κB通路相关。

将催化裂化汽油中的烯烃转化为高辛烷值的芳烃或异构烷烃是生产国Ⅵ标准清洁汽油的有效途径。锌改性ZSM-5(Zn/ZSM-5)分子筛是目前最好的烯烃芳构化催化剂。通过调整沸石的晶粒尺寸,系统地考察了不同粒径的ZSM-5沸石的酸性与烯烃选择性转化之间的构效关系。XRD、SEM、TEM、UV-Vis、XPS、FT-IR和NH3-TPD表征结果表明:ZSM-5的晶粒尺寸影响分子筛的酸性位分布,最小晶粒尺寸为100~200 nm的Zn/ZSM-5沸石具有最高ZnOH+活性物种的相对含量(Zn物种的57%)和较低的Bronsted酸与Lewis酸之比(A_(B)/A_(L)=0.15)。在反应温度350℃、液体进料液时体积空速(LHSV)为1.5 h^(-1)、H_(2)(g)和1-己烯(l)体积比为600、氢压为0.1和2.0 MPa条件下,该Zn/ZSM-5沸石催化剂在1-己烯加氢转化反应中分别表现出较高的芳烃选择性(17.2%)和异构烷烃选择性(50.0%)。这些数据表明,减小ZSM-5沸石晶粒尺寸有利于促进催化裂化汽油中烯烃向高辛烷值组分进行选择性转化。
