Dalu VillageA Probe into Preservation and Sustainable Development of Chinese Couplet Culture in Dalu Village

Dalu Village of Guangxi province is one of the national historical and cultural villages in China.It enjoys great fame for its Chinese couplets which are viewed as a distinctive cultural heritage passed down by its ancestors roughly 400 years ago.The couplets are a cultural art of great value worth preserving and inheriting.However,with urbanization and tourist development,the couplets are under the threat of devastation and disappearance.Based on desk research and field research,studies on the value of the couplets in Dalu Village and analysis of the rising crises are presented in the paper.In addition,solutions consisting of restoration,repair and ecomuseum are put forward as an attempt to avert the crises and promote the sustainable development of Dalu Village’s couplet culture in the long run.

Development history of hysteromyoma surgery with uterus preservation and introduction to each operation

Hysteromyoma is a gynecological multiple benign tumor disease,but it will still affect women's physical and mental health and may become malignant tumors.Therefore,it is necessary to treat it as soon as possible.Due to the lack of safe and effective medicine treatment with low recurrence rate,surgery is still the main treatment.Surgical treatment has a long history.This article introduces the history of surgical treatment of hysteromyoma.The earliest and most widely implemented is Laparoscopic myomectomy,which began in the 1920s.With the development of science and technology,Laparoscopic myomectomy,Hysteroscopic myomectomy and Transvaginal myomectomy in the late twentieth century gradually made the treatment of hysteromyoma minimally invasive.In recent years,laparoscopic uterine vascular occlusion combined with hysteromyomectomy,uterine artery embolization and high-intensity focused ultrasound have gradually appeared,and the treatment methods of hysteromyoma are becoming more and more perfect.

Exceptionally Preserved Punctatus triangulicostalis and Its Post-embryonic Development

Objective The putative coronatean Punctatus flourished at the beginning of the Cambrian explosion, and is significant in the exploration of the origin and evolution of early life. Liu Yunhuan established a new species： Punctatus triangulicostalis Liu, 2006. Two questions remain： how was the special body plan of P. triangulicostalis formed？ How does P. triangulicostalis transform from embryo to the long cylindrical mature individual？ Although the study of Steiner et al. in 2004 involved the above questions, they did not explain them clearly due to the lack of fossil materials at that time. This article aims to consider the above questions based on new information from several rare specimens.

Allograft of developing metanephroi into omenta of cyclosporine-treated adult rats after preservation

To evaluate the animal models and the effect on organogenesis and function of embryonic metanephroi allografted into cyclosporine-treated aduld rats after their preservation in histidine-tryptophan-ketoglutarate (HTK) solution.Methods Whole metanephroi preserved in HTK for 3 days from embryonic day 16 and 17 (E16,E17) of Sprague-Dawley (SD) rats were grouped and allografted into the omenta of cyclosporine-treated SD adult rats which had one kidney resected.E16 metanephroi implanted directly into omenta were used as controls.3 to 4 weeks after implantation,metanephroi allografted in host rats were removed for histopathological and electronic microscopy (EM) examination or anastomosed for renal function measurement 8 weeks later.Results 3 to 4 weeks post-implantation,E16 and E17 metanephroi had formed mature nephrons and collecting ducts with few lympocytic infiltration.EM examination showed they had cellular ultrastructure of normal nephrons and collecting ducts.E16 and E17 metanephroi allografted after preservation for 3 days had no significantly different values of wet weight (P=0.346,P=0.705),urine volume (P=0.396,P=0.687),and creatinine clearances (P=0.469,P=0.543) from those of E16 metanephroi implanted directly.Conclusion E16 and E17 metanephroi allografted into cyclosporine-treated adult rats undergo growth and differentiation and exhibit excretory function after preservation in HTK solution for 3 days.9 refs,1 tabs.

Distribution characteristics, exploration and development, geological theories research progress and exploration directions of shale gas in China

The shale gas resources in China have great potential and the geological resources of shale gas is over 100×10^(12)m^(3),which includes about 20×10^(12)m^(3) of recoverable resources.Organic-rich shales can be divided into three types according to their sedimentary environments,namely marine,marine-continental transitional,and continental shales,which are distributed in 13 stratigraphic systems from the Mesoproterozoic to the Cenozoic.The Sichuan Basin and its surrounding areas have the highest geological resources of shale gas,and the commercial development of shale gas has been achieved in the Upper Ordovician Wufeng Formation-Lower Silurian Longmaxi Formation in these areas,with a shale gas production of up to 20×10^(9)m^(3) in 2020.China has seen rapid shale gas exploration and development over the last five years,successively achieving breakthroughs and important findings in many areas and strata.The details are as follows.(1)Large-scale development of middle-shallow shale gas(burial depth:less than 3500 m)has been realized,with the productivity having rapidly increased;(2)breakthroughs have been constantly made in the development of deep shale gas(burial depth:3500-4500 m),and the ultradeep shale gas(burial depth:greater than 4500 m)is under testing;(3)breakthroughs have been made in the development of normal-pressure shale gas,and the assessment of the shale gas in complex tectonic areas is being accelerated;(4)shale gas has been frequently discovered in new areas and new strata,exhibiting a great prospect.Based on the exploration and development practice,three aspects of consensus have been gradually reached on the research progress in the geological theories of shale gas achieved in China.(1)in terms of deep-water fine-grained sediments,organic-rich shales are the base for the formation of shale gas;(2)in terms of high-quality reservoirs,the development of micro-nano organic matter-hosted pores serves as the core of shale gas accumulation;(3)in terms of preservation conditions,weak structural transformation,a moderate degree of thermal evolution,and a high pressure coefficient are the key to shale gas enrichment.As a type of important low-carbon fossil energy,shale gas will play an increasingly important role in achieving the strategic goals of peak carbon dioxide emissions and carbon neutrality.Based on the in-depth study of shale gas geological conditions and current exploration progress,three important directions for shale gas exploration in China in the next five years are put forward.

AONS Ⅱ： Continuing Preservation Software the Trend Towards ＇Nirvana＇

File format obsolescence is a major risk factor threatening the sustainability of and access to digital information. While the preservation community has become increasingly interested in tools for migration and transformation of file formats, the National Library of Australia is developing mechanisms specifically focused on monitoring and assessing the risks of file format obsolescence. This paper reports on the AONS II project, undertaken by the National Library of Australia (NLA) in conjunction with the Australian Partnership for Sustainable Repositories (APSR). The project aimed to develop a software tool which allows users to automatically monitor the status of file formats in their repositories, make risk assessments based on a core set of obsolescence risk questions, and receive notifications when file format risks change or other related events occur. This paper calls for the preservation community to develop a co-operating file format obsolescence community which includes registries, software tool creators and end users to effectively curate digital content in order to maintain long-term access.

面向碳中和的广东省电源结构转型分析

[目的]为实现“双碳”目标,电源侧的绿色低碳转型是广东实现绿色低碳转型的关键。同时,紧紧围绕新能源发展构建高比例新能源的多元电源支撑体系也是广东建设新型电力系统的重中之重。因此,提前谋划面向碳中和的广东电源结构具有十分重要的意义。[方法]在对广东省远景能源供需格局进行研判的基础上,统筹低碳转型和能源安全,考虑非化石能源消费比重、资源条件、电力供应平衡3个方面约束,提出广东面向碳中和的电源发展思路,对不同转型路径进行分析,并提出相关建议。[结果]研究表明,碳中和时期,广东省电源总装机规模预计将达到当前电源装机规模的3倍左右;电源供应主体由当前的“火电+核电+外电”组合,转变为“新能源+核电+外电”组合,非化石能源装机比重达到80%,其中,省内新能源装机比重达到50%。[结论]广东省的电源结构调整前景看似乐观,然而,这个过程仍然面临政策、技术、产业和市场等诸多挑战,建议转型过程中关注火电在电力系统中的定位转变、保障非化石能源发展关键要素、重视新型电力系统调节能力建设;为了满足碳中和时期广东两倍于现状的电力消费需求,更为重要的是需特别关注引领电源结构清洁低碳转型的科技创新问题,通过科技创新推动新能源类型、能源新技术的探索,向能量密度更大、能效转换效率更高的方向发展。
