Impact of redox-stratification on the diversity and distribution of bacterial communities in sandy reef sediments in a microcosm

Relationships between microbial communities and geochemical environments are important in marine microbial ecology and biogeochemistry. Although biogeochemical redox stratification has been well documented in marine sediments, its impact on microbial communities remains largely unknown. In this study, we applied denaturing gradient gel electrophoresis (DGGE) and clone library construction to investigate the diversity and stratification of bacterial communities in redox-stratified sandy reef sediments in a microcosm. A total of 88 Operational Taxonomic Units (OTU) were identified from 16S rRNA clone libraries constructed from sandy reef sediments in a laboratory microcosm. They were members of nine phyla and three candidate divisions, including Proteobacteria (Alpha-, Beta-, Gamma-, Delta-, and Epsilonproteobacteria), Actinobacteria, Acidobacteria, Bacteroidetes, Chloroflexi, Cyanobacteria, Firmicutes, Verrucomicrobia, Spirochaetes, and the candidate divisions WS3, SO31 and AO19. The vast majority of these phylotypes are related to clone sequences from other marine sediments, but OTUs of Epsilonproteobacteria and WS3 are reported for the first time from permeable marine sediments. Several other OTUs are potential new bacterial phylotypes because of their low similarity with reference sequences. Results from the 16S rRNA, gene clone sequence analyses suggested that bacterial communities exhibit clear stratification across large redox gradients in these sediments, with the highest diversity found in the anoxic layer (15-25 mm) and the least diversity in the suboxic layer (3-5 mm). Analysis of the nosZ, and amoA gene libraries also indicated the stratification of denitrifiers and nitrifiers, with their highest diversity being in the anoxic and oxic sediment layers, respectively. These results indicated that redox-stratification can affect the distribution of bacterial communities in sandy reef sediments.

Impacts of Integrated Multi-Trophic Aquaculture on Phytoplankton in Sanggou Bay

Integrated multi-trophic aquaculture(IMTA)has been considered as an ecofriendly culture system providing a potential solution to environmental risks caused by intensive monoculture system.However,the impact of IMTA on phytoplankton remains unclear.In this study,the spatial and temporal variations of phytoplankton in Sanggou Bay were investigated seasonally based on 21 sampling sites covering three cultivation zones(bivalve zone,IMTA zone,and kelp zone)and one control zone(without aquatic cultivation).In total,128 phytoplankton species,with diatoms and dinoflagellates as the dominant groups,were obtained across the whole year,and the mean Shannon diversity index(H')and species richness(SR)were determined as 1.39 and 9.39,respectively.The maximum chlorophyll a(Chl-a)(6.32μg L^(-1))and plankton diversity(H'of 1.97)occurred in summer and autumn,respectively.Compared to other zones,the bivalve zone displayed significantly higher Chl-a and lower H'in majority of time.Pairwise PERMANOVA analysis indicated that the phytoplankton assemblage in the bivalve zone was significantly different with the control and kelp zones,while the IMTA zone maintained close to other three zones.Based on generalized additive models,temperature,NO_(2)^(-)-N,N/P ratio,SiO_(3)^(2-)-Si,and salinity were determined as the key factors underlying Chl-a and phytoplankton diversity.Addi-tionally,the results of redundancy analysis further indicated that the phytoplankton assemblage in the bivalve zone is positively re-lated with nutrients such as NO_(3)^(-)-N and NH_(4)^(+)-N as well as water depth,while the phytoplankton assemblages in the kelp,control,and IMTA zones are associated with NO_(2)^(-)-N,SiO_(3)^(2-)-Si,and salinity.Taken all observations into consideration together,it can be inferred that IMTA can effectively reduce Chl-a level compared to bivalve monoculture by reducing the nutrients.However,the SR,H’,and species composition of phytoplankton are primarily determined by local environment factors such as temperature,water depth,salinity and SiO_(3)^(2-)-Si.

An Integrated Collector Storage Solar Water Heater and Study of its Temperature Stratification

In this paper we describe an integrated collector storage solar water heater for the North Western region of India for use as domestic water heater during the winter season and present the experimental results of temperature stratification. The system consists of a steel water storage tank with azimuthal orientation such that its walls face south east, south west, north east and North West directions. The sunlit walls (south east and south west) and the top cover surface of the storage tank are covered with transparent insulation material (TIM) and the off-sunlit sides with opaque insulation. Experimental results show that the top layer is at the highest temperature. The top layer is drained using a new design of the outlet. The system can be used in rural areas or as a pre heater in more affluent households. The system can return the cost of conversion of the storage tank into a Solar Water Heater in one winter season by saving the cost of electrical energy required for heating water during winter months.

A back analysis scheme for refined soil stratification based on integrating borehole and CPT data

Utilizing both borehole and Cone Penetration Testing(CPT)data in soil stratification helps to get more convincing soil stratification results.However,the soil classification results revealed by borehole(Unified Soil Classification System,USCS)and CPT tests(soil behavior type,SBT)are commonly not con-sistent.This study proposes a feasible solution to integrate the borehole and CPT data with the tree-based method.The tree-based method is naturally suitable for soil stratification tasks as it aims to divide the subsurface space into several clusters based on the similarities of the soil types.A novel boundary dic-tionary method is proposed to enhance the model performance on complex soil layer conditions.A prob-abilistic mapping matrix between the USCS-SBT system is built based on a collected municipal database with collocated borehole and CPT data.The optimal soil stratification results can be selected based on considering multiple borehole information and pruning the structure of trees.The structure of the trees can be optimized in a back analysis perspective with the Sequential Model-Based Global Optimization(SMBO)algorithm which aims to maximize the possibility of observing the borehole information based on the USCS-SBT probabilistic mapping matrix.The uncertainties of the optimal soil stratification results can be estimated based on a weighted Gini index method.The performance of the proposed method is validated based on a real case in New Zealand with a cross-validation method.The results indicate that the proposed method is robust and effective.

教育公平视野下普职分流的思考与启示

认同普职分流的观点主张普职分流有助于学生就业,有利于教育公平,有助于提升教育教学效率。反对普职分流的观点认为职业教育的专业对应的是社会底层的职业,依照才能选拔并不公平,不利于职教学生的发展。在目前的发展阶段,普职分流只是影响职业分层和教育公平的因素之一,它还受到社会、家庭、认知等诸多因素的影响。在推动现代教育体制高质量发展的背景下,需要通过实行普通教育与职业教育的错位发展,完善普职平等的教育制度,优化按劳分配的薪酬体系等措施,确保实现普职协调发展。

从多元一体格局的历史变迁看中华民族共同体意识的形成

以中国多元一体民族格局的历史文化变迁为视角来认识中华民族共同体意识的形成,以此来理解不同群体之间的互动和彼此关系,通过先秦华夏民族与华夏文明圈的出现、秦汉魏晋南北朝民族融合与中华民族共同体意识的初步形成、唐宋中华民族多元一体与中华民族共同体意识的巩固、明清“大一统”疆域与中华民族共同体意识的发展四个阶段民族互动与共同体意识形成的论述,可见从中国古代社会开始的各民族之间的共同体意识,已经维系了中华民族的团结与和谐,也必将进一步推动中华民族的进步与发展。

基于浮游植物生物完整性指数的福建省水库健康状态评价

根据2021年夏季福建省24座重要饮用水水源地水库水生态调查结果,分析了浮游植物群落结构特征和水库营养状态,并采用浮游植物总密度、香农-维纳多样性指数和蓝藻门密度百分比3个生物参数构建浮游植物生物完整性指数(P-IBI)评价了沙溪口水库和东张水库的健康状态。结果表明:2021年福建省大部分水库的浮游植物群落结构以蓝藻-绿藻-硅藻为主,其中以蓝藻门为优势藻的水库占比为60.9%;综合营养状态指数范围为24.3~51.7,平均值为40.3,水库富营养化程度较低,但个别水库仍存在富营养化的风险;沙溪口水库P-IBI综合得分为79.7,处于健康状态,东张水库P-IBI综合得分为59.0,处于亚健康状态;P-IBI评价结果与《2021年福建省河湖健康评估蓝皮书》中的多指标评价方法的结果一致性较好,基于浮游植物生物完整性指数的评价方法具有有效性和适用性。

南诏兵制渊源初探

南诏兵制之渊源大致可分为三元。其中,南诏内部多元文化为根本因素;以唐朝为代表的中原军政文化为直接因素;吐蕃告身、器物等制度文化对南诏兵制的影响则最小,是为表层因素。在南诏与唐、吐蕃的不断交往中,这种既荟萃了多种文化因子,又凝聚了本土特色的多元军事制度逐渐形成。究其实质,是云南地区多元文化走向一体化格局的反映,亦促进了中华民族“多元一体”格局的形成与发展。

中华文明起源视域下的北疆文化及其历史价值

中华文明多元起源已是学术界共识,以今内蒙古地区为主体区域的北部边疆在其中发挥了无可替代的重要历史作用。这是北疆文化形成的源头与基础,日益丰富的考古发掘材料也进一步证实了这一论断。目前已知北部边疆最早的人类活动遗址“大窑遗址”、证实中国现代人本土起源的“萨拉乌苏遗址”、展现中西方人类文明交流互动的“水洞沟遗址”与“鄂尔多斯式青铜器”,以及在中华文明起源研究中具有重要影响的“红山文化”等,都表明北部边疆在中国人类及中华文明起源过程中发挥了重要作用。此外,北部边疆与中国其他地区的人类及人类文明具有一定同步性,存在诸多相同或相似的因素。随着交流互动的逐渐增多与深入,各人类及人类文明区之间相互影响,彼此吸收对方先进的因素,共同推动了多元一体中华文明的起源、发展及繁荣。北部边疆在此过程中作出了自己的突出贡献,这既丰富了北疆文化的内涵,也奠定了它在中华文明尤其是中华文明起源研究中的重要地位。

用于放射性废物处理的HIC容器设计优化

核能作为清洁、高效的能源,是不可再生能源的重要替代品之一,也是我国优化能源结构、合理进行能源保护、开发与利用的有效选择,同时放射性核废物的处理也成了核电发展的一个重要环节。相比于传统的水泥固化技术,高完整性容器(HIC)能够直接盛放干燥后的放射性废树脂和浓缩液干燥盐,具有更高的废物最小化水平,成为放射性废物管理的主要的发展方向之一。本文针对目前混凝土高完整性容器体积较大、防上浮效果不佳以及内容物包覆性差的缺点,进行设计优化,开发出具有更高性能的混凝土高完整性容器并进行了一定的工程应用验证,为核电厂和化工厂产生的放射性废物的高效处理提供了技术支持。

垂直视角下杭州市滨江区街道绿化差异与融合分析

针对目前城市街道绿化多指标评价的缺乏,文章以杭州市滨江区为例,从垂直视角,以百度街景为数据源,利用FCN-8S语义分割模型识别并计算街道绿视率与植被层次性,再通过熵权法融合数据以实现街道绿化整体评价。结果表明:滨江区绿视率与植被层次性在空间分布上差异较大;滨江区综合绿化存在地区差异性;滨江区多数街道绿化分布分散且不均匀,稳定性较差。因此,未来街道绿化建设中:应按需兼顾绿化数量及层次性,注重植被配置,减小地区绿化差异;应结合城市建设需求,加强街道绿化稳定性,美化城市形象。

从元杂剧到小说——论百回本《西游记》承继的民族文化观

元代杂剧西游故事无论是在取材还是叙述形式上均影响了吴承恩百回本《西游记》的创作,学界对此展开的研究成果也较多。事实上,吴承恩在对“俗”文本继承的基础上,对元杂剧西游故事中出现的民族文化融合与交流的因素作了相当的改良,使得百回本《西游记》成为“俗”中见“雅”、集结文学观赏性与思想深度的中国经典文学作品。研究元杂剧西游故事与百回本西游故事之间的关联有利于我们进一步掌握中国文学作品所蕴含的多元文化色彩与民族文化融合思想,对当今的文学创作具有启示意义。
