中国作为港口大国,上海港的集装箱吞吐量连续多年世界第一。2019年12月暴发的新冠疫情对世界航运造成了巨大影响,对上海港的影响程度及其集装箱吞吐量的未来走势亦未可知。因此,本文以上海港过去9年的集装箱吞吐量月度数据为原始样本,对上海港2022年11月至2023年10月的集装箱吞吐量进行预测。为排除季节效应,建立SARIMA模型进行时间序列分析,结果表明预测精度良好。另外,为减小疫情对未来预测值的影响,利用异常值替换法改进了基础模型,并选取最优模型对上海港未来集装箱吞吐量进行预测,结果可为行业人员制定作业计划与人员配备提供参考。

高校辅导员是大学生思想政治教育的关键力量,其思政育人能力是辅导员队伍建设和高校思政工作开展的重要保障。通过分析高校辅导员在思政育人中的角色定位发现,辅导员在高校思政教育工作中承担着思政知识传承者、校园舆论监督者、思政价值传播者等不同角色。利用德尔菲法建立了4个一级指标、16个二级指标的高校辅导员思政育人能力评价指标体系,从思政素养、教学能力、职业道德、思政运用等四方面对辅导员的思政育人能力进行评价。一级指标中,思政素养和思政运用2个指标所占权重较大。二级指标中,政治信仰、思想道德、思政教学设计、思政教学内容等指标所占权重较高。

随着互联网的高速发展,数字技术已成为高校教育管理的重要组成部分。以互联网的高速发展为研究背景、高校学生数字化管理为主线设计相关调查问卷,运用描述性统计分析、回归模型、满意度均值计算等方法对问卷调查结果进行统计分析。结果表明,八成以上的受访者认为高校辅导员、教职工及高校需要提高数字化能力。二成以上的受访者认为现阶段的数字化管理平台解决问题的效果还有待加强。基于此,高校应加强数字化基础设施建设,提高数字化系统功能的完备性。同时,应加强对教师的数字化水平培训,提升高校数字化应用水平。

目的:探讨N端-B型脑钠肽前体(NT-proBNP)、降钙素原(PCT)和胆碱酯酶(ChE)在心衰伴肺部感染患者预后中的诊断价值。方法:选择2022年3月—2023年10月庆阳市中医医院收治的100例心衰伴肺部感染患者作为观察组,另选取同期本院收治的60例单纯心衰患者作为对照组。随访6个月,根据观察组的预后情况将其分为死亡组(n=29)与生存组(n=71)。通过磁微粒化学发光法检测各组患者血清中NT-proBNP、PCT和ChE水平。采用受试者操作特征(ROC)曲线分析各指标对心衰伴肺部感染患者预后的预测效能。结果:观察组NT-proBNP和PCT水平均显著高于对照组,ChE水平显著低于对照组,差异均有统计学意义(P<0.05)。死亡组NT-proBNP和PCT水平均显著高于生存组,ChE水平显著低于生存组,差异均有统计学意义(P<0.05)。ROC曲线结果表明,NT-proBNP、PCT和ChE预测心衰伴肺部感染患者预后不良的敏感度分别为79.3%、79.3%、93.1%,特异度分别为90.1%、84.5%、53.5%,AUC分别为0.902、0.873、0.713,而NT-proBNP、PCT和ChE联合预测的敏感度和特异度分别提升至93.1%和93.0%,AUC值则达到0.975,均高于NT-proBNP、PCT、ChE单独检测。结论:NT-proBNP、PCT和ChE作为诊断心衰伴肺部感染患者预后的生物标志物具有显著的诊断效能,尤其是三者联合检测,可为临床提供重要的预后评估信息。

In this paper, the process of photocatalytic reduction of hexavalent chromium was investigated over Ti3＋- modified TiO2 photocatalysts. The Ti3＋ surface defects were repaired by annealing as-prepared sample at different temperatures to control the amount of Ti3＋ sites. The samples were characterized by SEM, XRD, BET, UV-Vis absorption, EPR and XPS. The results showed Ti3＋ defects were successfully doped in TiO2. The surface selective adsorption of hexavalent chromium [Cr2072 （Cr（VI））] and the desorption of trivalent chromium [Cr3＋（Cr（III））] were investigated during the process ofphotocatalytic reduction positive charges due to more Ti3＋ defects on the surface show a Accordingly, the surface positive reduction of Cr（VI）. charges controlled by the Ti3＋ Zeta potential results presented that the increased significant improvement for adsorption of Cr（VI）. defects play important roles in the photocatalytic

页岩纹层发育,微观非均质性强,页岩破裂方式受多种因素控制。以川南地区X101井龙马溪组深层页岩为研究对象,利用岩芯、薄片、测井资料、X-射线衍射与CT扫描等手段,结合单轴压缩与常规三轴压缩实验,系统研究了页岩破裂方式与纹层产状、矿物组成的关系。结果表明,主压应力垂直纹层方向的单轴压缩岩样形成张拉劈裂破坏,产生80°左右的垂直缝;三轴压缩实验中,主压应力垂直于纹层的岩样形成剪切破坏,裂缝与纹层以45°∼65°高角度斜交,主压应力与纹层45°斜交的岩样以沿纹层面的剪切滑移破坏为主,主压应力平行纹层的岩样产生共轭剪切破坏,两者形成的裂缝与纹层呈10°∼45°低角度斜交。对于不同纹层倾角的岩样,杨氏模量均与石英含量呈显著正相关,与黏土矿物呈显著负相关的关系,抗压强度与石英、黏土矿物含量的相关性受不同纹层倾角的影响。硅质纹层发育单层厚度大将增强页岩力学性质。
