This paper celebrates Professor Yongqi GAO's significant achievement in the field of interdisciplinary studies within the context of his final research project Arctic Climate Predictions: Pathways to Resilient Sustainable Societies-ARCPATH(https://***/en/projects/finished-projects/arcpath). The disciplines represented in the project are related to climatology, anthropology, marine biology, economics, and the broad spectrum of social-ecological studies. Team members were drawn from the nordic countries, Russia, China, the United States, and Canada. The project was transdisciplinary as well as interdisciplinary as it included collaboration with local knowledge holders. ARCPATH made significant contributions to Arctic research through an improved understanding of the mechanisms that drive climate variability in the Arctic. In tandem with this research, a combination of historical investigations and social, economic, and marine biological fieldwork was carried out for the project study areas of Iceland, Greenland, norway, and the surrounding seas, with a focus on the joint use of ocean and sea-ice data as well as social-ecological drivers. ARCPATH was able to provide an improved framework for predicting the near-term variation of Arctic climate on spatial scales relevant to society, as well as evaluating possible related changes in socioeconomic realms. In summary, through the integration of information from several different disciplines and research approaches, ARCPATH served to create new and valuable knowledge on crucial issues, thus providing new pathways to action for Arctic communities.

A new aberrant species of the genus Sphaerostoma(Trematoda: Opecoelidae) from the Amur River basin

引用

Zoological Systematics 2024年第4期 352-360页

作者： sergey G.Sokolov Sergei V.Shchenkov Evgeniy V.Frolov Sergei A.Vlasenkov A.n.Severtsov Institute of Ecology and Evolution RAS Department of Invertebrate Zoology St.Petersburg State University Sakhalin Branch of Russian Federal Research Institute of Fisheries and Oceanography

A new freshwater opecoelid species, Sphaerostoma tamarae sp. nov., is described from Rhynchocypris percnura mantschurica caught in the Syumnyur River(Amur River basin,Russia). This parasite species differs from all other congeners in the distribution of the vitelline follicles(restricted to the hindbody) and the morphology of the ventral sucker(strongly protuberant). Molecular phylogenetic analysis based on 28S rRnA gene sequences and the morphological analysis allow to tentatively assign the new species to the genus Sphaerostoma,without closing the question regarding the true genus affiliation of this species. In addition, the authors provide an argument for renaming the Plagioporinae to the Sphaerostomatinae.

厘清农村劳动力转移与耕地利用可持续集约化之间的关系对于促进农业可持续发展具有重要意义。该研究基于1990—2020年中国省级面板数据，采用超效率SBM模型测算耕地利用可持续集约化水平，运用面板门槛模型探讨农村劳动力转移对耕地利用可持续集约化的影响效应。结果表明：1)1990—2020年中国耕地利用可持续集约化水平总体呈先下降后上升的趋势，区域间差异显著；2）农村劳动力转移对耕地利用可持续集约化存在非线性影响，当农村劳动力转移水平小于0.351时，农村劳动力转移不利于耕地利用可持续集约化的增长；超过这一门槛后，农村劳动力转移对耕地利用可持续集约化产生显著的增长效应；3）农村劳动力转移对耕地利用可持续集约化的影响存在非均衡效应，即农村劳动力转移对农业发达地区与平原地区的促进作用显著，但对农业欠发达地区与山地地区的促进作用尚不显著。基于此，应合理引导农村冗余劳动力非农转移，以推动耕地利用可持续集约化转型；同时，应注意耕地利用可持续集约化提升的自然环境禀赋与农业经济发展水平制约，因地制宜的探索适宜地区条件的耕地利用可持续集约化发展路径。

Mathematical Modeling of Heat Transfer Processes of Coal Waste Combustion in a Chamber of Automated Energy Generating Complex

引用

Journal of Thermal Science 2013年第2期22卷 174-179页

作者： sergey P. Mochalov sergey n. Kalashnikov Pavel S. Mochalov Guolin Song Guoyi Tang Siberian State Industrial University Advanced Materials Institute Graduate School at ShenzhenTsinghua University

The automated energy generating complex allows obtaining heat energy from waste coal-water slurry fuel （WCF） that is a mixture of fine coal particles from coal enrichment wastes with water. The mixture is blown into the swirl chamber under the pressure through the special sprayers. The received heat energy is used in different ways. One of the important issues is to estimate the heat losses through the walls of this chamber. In this paper we solved the boundary problem of mathematical physics to estimate the temperature fields in the walls of the swirl chamber. The obtained solution allows us to estimate the heat losses through the waUs of the swid chamber. The task of the mathematical physics has been solved by a numerical finite-difference method. The method for solving this prob- lem can be used in the calculation of temperature fields and evaluation of heat losses in other thermal power units.
