Unfortunately, many local and indigenous chicken breeds are at risk of declining numbers, emphasizing the need to conserve breed resources for endangered chickens. Primordial germ cells(PGCs) are crucial for preserving germplasm resources by inheriting genetic information from parents to offspring and ensuring stability of genetic material between germlines. In this study,PGCs were isolated from chicken embryos' gonads and cultured in FAcs medium without feeder cells. Over a period of approximately 40 d, the cells proliferated to a number of up to 10^(6), establishing various cell lines. Particularly, 18 PGC lines were created from Rugao Yellow chicken and Shouguang chicken, with an efficiency ranging from 39.1 to 45%. Furthermore, PGCs that had been cultured for 40 passages exhibited typical PGC characteristics, suchas glycogen staining reaction, and expression of pluripotency and reproductive markers. These results confirmthat PGCs maintain stem cell properties even after long-term in vitro culture. Additionally, PGCs cryopreserved for up to 120 d remained viable, maintained typical PGC morphologies, and possessed stable cell proliferation ability. Through intravascular injection into chicken embryos, green fluorescent protein(GFP)-PGCs were found in the recipient embryos' gonads and could develop into gametes to produce offspring, indicating that even after extended culture, PGCs retain their migratory and lineage-transmitting capabilities. This research offers valuable insights into the in vitro cultivation and preservation of PGCs of Chinese indigenous chickens. The findings of this study can be applied in transgenic chicken production and the preservation of genetic resources of indigenous chicken breeds.展开更多

文摘The Polar Regions host one of the harshest and most unique ecosystems on Earth,harboring a diverse array of micro-and macro-organisms.These inhabitants showcase remarkable taxonomic and genetic originality,presenting unparalleled opportunities for bioprospecting,alongside demonstrating extraordinary adaptation mechanisms for survival.Furthermore,polar organisms play crucial roles in facilitating organic matter decomposition,carbon fixation and sequestration,and biogeochemical cycling.Moreover,these organisms serve as pivotal indicators of global climate shifts.Therefore,exploring the polar organisms and ecosystem holds profound and significant implications for gaining deeper insights into scientific frontiers such as global biodiversity,elementary cycling,climate change,resource utilization,and the awe of life in extreme environments.
文摘This paper aims to investigate the effect of SME’s resources including,financial resources(FRR),financial literacy(FLR),managerial capacities(MCR)and market orientation(MKR)on SME’s sustainable growth(SG)in both financial SG(FSGE)and non-financial SG(NFSGE)terms;and to identify the technological innovation awareness(TIR)mediates the effect of these resources on SGSMEs.Data were collected from 517 SMEs,using survey method and adopted a random sampling technique.Structure Equation Model(SEM)and the Baron,and Kenny(1986)mediation approach,Amos was applied to test hypotheses.The findings revealed the resources contributed 41.9 percent and 32.9 percent of the variance in FSGE and NFSGE,respectively,and confirmed the mediating role of TIR in the relationship between resources and SG.Notably,FRR had an indirect effect on FSGE through TIR,although TIR partially mediated the relationship between FRR and NFSGE,and between FLR and SG,both in FSGE and NFSGE terms.While,TIR fully mediated the relationship between MKR and SG,both in FSGE and NFSGE terms as well.This evidence informs the importance of business resources and competencies.In particular,TIR plays an important role in business operations to enhance and maintain sustainable growth.

文摘Economic growth affects natural resources and the environment directly and indirectly;however,the exact role that natural resources play in environmental sustainability remains unknown.This paper revisits the relationship between natural resources and CO_(2)emissions by considering the role of green finance vis-à-vis the aggregated and disaggregated analysis.Empirical panel data estimation analyzes a sample of emerging countries over the 2001-2019 period using the recently developed econometric cross-sectional auto-regressive distributed lag(CS-ARDL)technique.The findings show that natural resource components(natural gas,mineral rent,oil rent,and coal rent)are negatively associated with environmental pollution.In contrast,overall natural resource consumption helps reduce carbon emissions.However,we find that green finance contributes to carbon emission reduction.In contrast,education causes pollution by contributing to carbon emissions.We offer policy recommendations about the effectiveness of green financing for the sustainable use of natural resources in diminishing pollution.
文摘This study focuses on the risks associated with the on-balance sheet recognition of data resources.At the legal level,disputes over ownership often arise due to unclear data property rights,while privacy protection,cybersecurity,and cross-border data flows create additional compliance challenges.In terms of recognition,the subjectivity of traditional valuation methods,the lack of active markets,and the rapid depreciation of data value caused by technological iteration hinder reliable measurement.With respect to disclosure,organizations face a dilemma between transparency and confidentiality.Collectively,these issues exacerbate audit risks.It is therefore imperative to establish an appropriate legal,accounting,and auditing framework to mitigate such risks and remove barriers to the proper recognition of data assets on balance sheets.

文摘The integration of substantial renewable energy and controllable resources disrupts the supply-demand balance in distribution grids.Secure operations are dependent on the participation of user-side resources in demand response at both the day-ahead and intraday levels.Current studies typically overlook the spatial--temporal variations and coordination between these timescales,leading to significant day-ahead optimization errors,high intraday costs,and slow convergence.To address these challenges,we developed a multiagent,multitimescale aggregated regulation method for spatial--temporal coordinated demand response of user-side resources.Firstly,we established a framework considering the spatial--temporal coordinated characteristics of user-side resources with the objective to min-imize the total regulation cost and weighted sum of distribution grid losses.The optimization problem was then solved for two different timescales:day-ahead and intraday.For the day-ahead timescale,we developed an improved particle swarm optimization(IPSO)algo-rithm that dynamically adjusts the number of particles based on intraday outcomes to optimize the regulation strategies.For the intraday timescale,we developed an improved alternating direction method of multipliers(IADMM)algorithm that distributes tasks across edge distribution stations,dynamically adjusting penalty factors by using historical day-ahead data to synchronize the regulations and enhance precision.The simulation results indicate that this method can fully achieve multitimescale spatial--temporal coordinated aggregated reg-ulation between day-ahead and intraday,effectively reduce the total regulation cost and distribution grid losses,and enhance smart grid resilience.

文摘Wells CXD1 and CX2 have uncovered high-concentration potassium-and lithium-containing brines and substantial layers of halite-type polyhalite potash deposits within the 4th and 5th members of the Triassic Jialingjiang Formation and the 1st Member of Leikoupo Formation(Jia 4 Member,Jia 5 Member,and Lei 1 Member)in the Puguang area,Sichuan Basin.These discoveries mark significant breakthroughs in the exploration of deep marine potassium and lithium resources within the Sichuan Basin.Utilizing the concept of“gas-potassium-lithium integrated exploration”and incorporating drilling,logging,seismic,and geochemical data,we have investigated the geological and enrichment conditions,as well as the metallogenic model of potassium-rich and lithium-rich brines and halite-type polyhalite.First,the sedimentary systems of gypsum-dolomite flats,salt lakes and evaporated flats were developed in Jia 4 Member,Jia 5 Member,and the 1st member of Leikoupo Formation(Lei 1 Member)in northeastern Sichuan Basin,forming three large-scale salt-gathering and potassium formation centers in Puguang,Tongnanba and Yuanba,and developing reservoirs with potassium-rich and lithium-rich brines,which are favorable for the deposition of potassium and lithium resources in both solid or liquid phases.Second,the soluble halite-type polyhalite has a large thickness and wide distribution,and the reservoir brine has a high content of K+and Li+.A solid-liquid superimposed“three-story structure”(with the lower thin-layer of brine reservoir in lower part of Jia 4 Member and Jia 5 Member,middle layer of halite-type polyhalite potash depositS,upper layer of potassium-rich and lithium-rich brine reservoir in Lei 1 Member)is formed.Third,the ternary enrichment and mineralization patterns for potassium and lithium resources were determined.Vertical superposition of polyhalite and green bean rocks is the mineral material basis of potassium-lithium resources featuring“dual-source replenishment and proximal-source release”,with primary seawater and gypsum dehydration as the main sources of deep brines,while multi-stage tectonic modification is the key to the enrichment of halite-type polyhalite and potassiumlithium brines.Fourth,the ore-forming process has gone through four stages:salt-gathering and potassium-lithium accumulation period,initial water-rock reaction period,transformation and aggregation period,and enrichment and finalization period.During this process,the halite-type polyhalite layer in Jia 4 Member and Jia 5 Member is the main target for potassium solution mining,while the brine layer in Lei 1 Member is the focus of comprehensive potassium-lithium exploration and development.
文摘Natural resources,green energy,and sustainable development are closely linked with concepts that carry mutual goals to endorse social equity,economic prosperity,and ecological stability while curtailing the harmful influence on the globe.However,the recognition of the Sustainable Development Goals(SDG-7,SDG-13)is closely entangled with digital economy.In this pursuit,this study scrutinizes the effect of dig-italization,renewable energy,and natural resources on the ecological footprint in China from 1990Q1-2022Q4.The empirical analyses are carried out by employing the Quantile-on-Quantile regression,and cross-quantile and partial cross-quantile correlation approaches to inspect the tail dependence of model parameters.The empirical outcomes highlight how China’s environmental quality is influenced by exoge-nous variables,including digitalization index,renewable energy consumption,and natural resources.Digitalization has adverse impact on the ecological footprint in lower quantiles,while insignificant in higher quantiles.Moreover,a strong adverse association exists between ecological footprint and renew-able energy,which syndicate all the quantiles of renewable energy with linking over lower to middle quantiles and weak in higher quantiles of ecological footprint.Besides,the estimated analysis discloses nuanced dependencies across various quantiles.Similarly,it can be found that the strong negative effect of natural resources on ecological footprint in initial quantiles,moderate in middle quantiles,and less positive effect in higher quantiles.By explaining these dynamics,the current study offers valuable intu-itions designed at controlling China toward its dual-carbon target and encouraging the development of a sustainable digital and green economy and thereby,continuing towards achieving SDG-7,and SDG-13 objectives.

文摘Germplasm resources are essential for the sustainable development of biodiversity and husbandry of local chickens, as well as for the breeding and industry of superior quality chickens. Unfortunately, many local and indigenous chicken breeds are at risk of declining numbers, emphasizing the need to conserve breed resources for endangered chickens. Primordial germ cells(PGCs) are crucial for preserving germplasm resources by inheriting genetic information from parents to offspring and ensuring stability of genetic material between germlines. In this study,PGCs were isolated from chicken embryos' gonads and cultured in FAcs medium without feeder cells. Over a period of approximately 40 d, the cells proliferated to a number of up to 10^(6), establishing various cell lines. Particularly, 18 PGC lines were created from Rugao Yellow chicken and Shouguang chicken, with an efficiency ranging from 39.1 to 45%. Furthermore, PGCs that had been cultured for 40 passages exhibited typical PGC characteristics, suchas glycogen staining reaction, and expression of pluripotency and reproductive markers. These results confirmthat PGCs maintain stem cell properties even after long-term in vitro culture. Additionally, PGCs cryopreserved for up to 120 d remained viable, maintained typical PGC morphologies, and possessed stable cell proliferation ability. Through intravascular injection into chicken embryos, green fluorescent protein(GFP)-PGCs were found in the recipient embryos' gonads and could develop into gametes to produce offspring, indicating that even after extended culture, PGCs retain their migratory and lineage-transmitting capabilities. This research offers valuable insights into the in vitro cultivation and preservation of PGCs of Chinese indigenous chickens. The findings of this study can be applied in transgenic chicken production and the preservation of genetic resources of indigenous chicken breeds.
