乡村振兴背景下,我国乡村文化的建设和发展正快速推进,依托新媒体网络化时代化发展与文化全球化发展的大背景,乡村文化开始走进千家万户。以云南民族村为代表的乡村文旅景区正逐步向“新媒体+乡村文化”转型,当地古村落文化留存完整,文化资源丰富,旅游业等产业发展基础良好,还利用假期推出“安心‘云’上游”活动,展现民俗文化的独特风味。然而传播过程中仍然存在些许问题,包括推广传播形式单一,对外传播效果不显著,传播内容缺乏人文价值等。本文以云南民族村为例,通过个案研究分析乡村文化传播存在不足与发展潜力,在此基础上形成乡村文化在新时代下的对外传播策略。

研究表明低矿化度水注水(LSW)具有提高采收率的潜力。考察二氧化硅纳米颗粒(NPs)在砂岩上的吸附以及其在LSW驱油过程中对流体/岩石相互作用的影响。在砂岩表面的等温静态吸附实验中,纳米颗粒在石英表面表现出比高岭石更高的吸附亲和力。随着盐度的增加,纳米颗粒的吸附能力增强。动态吸附实验中,注入约0.033 g纳米颗粒与示踪剂(约0.13 g氯化锂),估计NPs在岩心驱替过程中的不可逆吸附约为35%,而岩心驱替的解吸率约为21.2%。质量平衡分析实验结果显示,pH对纳米二氧化硅的吸附/脱附过程有一定影响,碱度的增加有利于纳米颗粒的脱附。与单独使用LSW和NP驱相比,在LSW和NP复合驱过程中,纳米颗粒在矿物表面的吸附减少了矿物的溶解。表面力估算表明,LSW与NPs的结合降低了矿物颗粒之间的斥力。将LSW和纳米颗粒相结合形成协同效应,从而降低了砂岩储层的地层损害概率。

The kinetic competition between electron-hole recombination and water oxidation is a key limitation for the development of efficient solar water splitting materials. In this study, we present a solution for solving this challenge by constructing a quantum dot-intercalated nanostructure. For the first time, we show the interlayer charge of the intercalated nanostructure can significantly inhibit the electron-hole recombination in photocatalysis. For Bi2WO6 quantum dots （QDs） intercalated in a montmorillonite （MMT） nanostructure as an example, the average lifetime of the photogenerated charge carriers was increased from 3.06 μs to 18.8 Ds by constructing the intercalated nanostructure. The increased lifetime markedly improved the photocatalytic performance of Bi2WO6 both in solar water oxidation and environmental purification. This work not oMy provides a method to produce QD-intercalated ultrathin nanostructures but also a general route to design efficient semiconductor-based photoconversion materials for solar fuel generation and environmental purification.

商用车碳减排已经成为我国道路交通减碳的关键瓶颈,新能源商用车被视作重型商用车减碳的重要途径,但是新能源商用车的市场渗透率远低于其他车辆部门;但与此同时,现阶段新能源零碳商用车的发展还存在着应用场景复杂、技术路径多样化、同时成本较高的显著的瓶颈。本研究构建了基于新能源汽车总拥有成本(total cost of ownership,TCO)、使用便利性等因素的多元Logit离散选择模型——零碳商用车市场演进模型(discrete choice-based market evolution of green truck model,DC-MEGT),使用自下向上的方法计算TCO,并将车辆使用便利性使用补能时间成本进行货币化量化,构建综合效用函数对纯电动车、燃料电池汽车及零碳燃料等不同动力类型从目前到2060年的市场渗透率演进情况进行预测分析。研究以重型长途牵引场景为例进行分析,结果表明2060年主要的技术路径包括燃料电池汽车、纯电动车、天然气及柴油车,占比分别为48%、28%、12%和10%。政策推广、技术进步、商业模式等因素的不确定性会引发纯电动车和燃料电池汽车2060年市场份额17%~19%的波动。

目的旨在揭示普罗维登斯菌中质粒不相容群IncpPrY2001的基因组结构和遗传特征。方法 16S rDNA初步鉴定菌种后,将菌株送二代和三代测序,得到测序数据后进行平均核苷酸一致性(ANI)比对,最终核定菌种;VITEK 2仪器检测细菌的最小抑菌浓度(MIC)值;随后进行全基因组测序,获得细菌的全基因组序列,通过精细注释及比较基因组学分析,确定耐药基因所在基因环境。结果该研究指定了1个新的质粒型别IncpPrY2001。IncpPrY2001型质粒与参考质粒pPrY2001具有相似的骨架保守区,但插入区存在差异。IncpPrY2001型质粒的插入区表现出了显著的多样性,这表明质粒内部存在大量的基因获得和缺失,包括5个Tn1696和1个Tn7相关的区域。在IncpPrY2001型质粒中发现了多种抗生素耐药基因(ARG),涉及对至少8类12种的抗生素的耐药性。发现包含In1806和In1807在内的2个新的可移动遗传元件(MGE)。结论 IncpPrY2001型质粒中插入了大量携带耐药基因的MGE,有助于ARG的积累和分布,同时增强了普罗维登斯菌株在药物选择压力下的生存能力。
