The Theoretical Connotation and Systematic Essence of Core Competence of Agricultural High-tech Enterprises

Six representative interpretations about the core competence of the corporate proposed by the researchers both at home and abroad from different perspectives are introduced,which includes "Resource theory","Capacity theory","Integration theory of assets and mechanism","Theory of consumer surplus","Theory of institutions and systems" and "Theory of innovation". It is pointed out that although these interpretations play an active role in enriching the theory of core competence,it still faces the problems to further deepen these interpretations:the first problem is how to give a precise definition;the second is about its extension;the third is on the logical and practical relationship between the production mechanism and its sustainable competitive advantages;the fourth is the problems in the production process and the corresponding management. Both the systematic essence and features of core competence are introduced:the first is the system self-organization process produced within the corporate;the second is the interaction between corporate system and environment;it needs a growing and evolution process. This paper briefly describes the essence of core competence of agricultural high-tech corporate,introduces its five features including systematicness,integration,non-imitation,ductility and non-equilibrium,and finally explains its component parts,mainly including corporate culture system,technological innovation system,human resource system,management capability system,corporate production and marketing system,financial capability system and adaptability system.

Distributed heterogeneous inspecting system and its middleware-based solution

There are many cases when an organization needs to monitor the data and operations of its super-vised departments, especially those departments which are not owned by this organization and are managed by their own information systems. Distributed Heterogeneous Inspecting System (DHIS) is the system an organization uses to monitor its supervised departments by inspecting their information systems. In DHIS, the inspected systems are generally distributed, heterogeneous, and constructed by different companies. DHIS has three key processes-abstracting core data sets and core operation sets, collecting these sets, and inspecting these collected sets. In this paper, we present the concept and mathematical definition of DHIS, a metadata method for solving the interoperability, a security strategy for data transferring, and a middleware-based solution of DHIS. We also describe an example of the inspecting system at WENZHOU custom.

Hydrologic Response to Future Climate Change in the Dulong-Irra-waddy River Basin Based on Coupled Model Intercomparison Project 6

Within the context of the Belt and Road Initiative(BRI)and the China-Myanmar Economic Corridor(CMEC),the Dulong-Ir-rawaddy(Ayeyarwady)River,an international river among China,India and Myanmar,plays a significant role as both a valuable hydro-power resource and an essential ecological passageway.However,the water resources and security exhibit a high degree of vulnerabil-ity to climate change impacts.This research evaluates climate impacts on the hydrology of the Dulong-Irrawaddy River Basin(DIRB)by using a physical-based hydrologic model.We crafted future climate scenarios using the three latest global climate models(GCMs)from Coupled Model Intercomparison Project 6(CMIP6)under two shared socioeconomic pathways(SSP2-4.5 and SSP5-8.5)for the near(2025-2049),mid(2050-2074),and far future(2075-2099).The regional model using MIKE SHE based on historical hydrologic processes was developed to further project future streamflow,demonstrating reliable performance in streamflow simulations with a val-idation Nash-Sutcliffe Efficiency(NSE)of 0.72.Results showed that climate change projections showed increases in the annual precip-itation and potential evapotranspiration(PET),with precipitation increasing by 11.3%and 26.1%,and PET increasing by 3.2%and 4.9%,respectively,by the end of the century under SSP2-4.5 and SSP5-8.5.These changes are projected to result in increased annual streamflow at all stations,notably at the basin’s outlet(Pyay station)compared to the baseline period(with an increase of 16.1%and 37.0%at the end of the 21st century under SSP2-4.5 and SSP5-8.5,respectively).Seasonal analysis for Pyay station forecasts an in-crease in dry-season streamflow by 31.3%-48.9%and 22.5%-76.3%under SSP2-4.5 and SSP5-8.5,respectively,and an increase in wet-season streamflow by 5.8%-12.6%and 2.8%-33.3%,respectively.Moreover,the magnitude and frequency of flood events are pre-dicted to escalate,potentially impacting hydropower production and food security significantly.This research outlines the hydrological response to future climate change during the 21st century and offers a scientific basis for the water resource management strategies by decision-makers.

Introduction of temperature-sensitive helper and donor plasmids into Bac-to-Bac baculovirus expression systems

In the baculovirus shuttle vector(bacmid) system, a helper plasmid and a donor plasmid are employed to insert heterologous genes into a cloned baculovirus genome via Tn7 transposition in Escherichia coli. The helper and donor plasmids are usually cotransfected with constructed bacmids into insect cells, which will lead to integration of these plasmids into the viral genome,and hence to the production of defective virions. In this study, to facilitate the preparation of plasmid-free recombinant bacmids, we modified a set of helper and donor plasmids by replacing their replication origins with that of a temperature-sensitive(ts) plasmid, p SIM6. Using the resulting ts helper plasmid p MON7124 ts and the ts donor plasmid p FB1ts-PH-GFP, a recombinant bacmid,b Ac WT-PG(-), was constructed, and the transposition efficiency was found to be 33.1%. The plasmids were then removed by culturing at 37 °C. For b Ac WT-PG(-), the infectious progeny virus titer and the protein expression level under the control of the polyhedrin promoter were similar to those of a bacmid constructed with unmodified helper and donor plasmids. These ts plasmids will be useful for obtaining plasmid-free bacmids for both heterologous protein production and fundamental studies of baculovirus biology.

基于Cu掺杂BiOBr光阴极的生物光电化学系统降解典型抗生素的特性及微生物群落响应

抗生素难以生物降解且会诱导产生抗性基因,对生态环境和人体健康均造成威胁,因此,抗生素废水的高效处理意义重大.本研究制备了Cu掺杂的BiOBr光阴极,并与生物阳极耦合,构建生物光电化学系统(biophotoelectrochemical system,BPES),用于降解抗生素.结果表明,Cu-BiOBr较BiOBr具有更优异的光电化学性能.光照条件下的BPES在48 h内对初始浓度为20 mg·L^(-1)的阿莫西林(AMX)的去除率达91.38%.此外,适当曝气可提高BPES对AMX的去除.当AMX与盐酸四环素(TC),磺胺甲恶唑(SMX)在BPES中共降解时,降解过程均受到不同程度的抑制.根据鉴定的AMX的降解中间产物,推断了AMX的降解路径.BPES的阳极生物膜上的微生物主要以电活性细菌Geobacter为主,其对抗生素具有较高耐受性以及降解能力.
