Sedimentology and sequence stratigraphy of the mixed clastic-carbonate deposits in the Late Paleozoic icehouse period:A case study from the northern Qaidam Basin

The widely-developed,mixed clastic-carbonate succession in the northern Qaidam Basin records the paleo-environment changes under the glacial activity during the Late Paleozoic icehouse period in the context of regional tectonic stability,however,the depositional environment and sequence stratigraphy characteristics of the mixed deposits is rarely reported and still not clear.Combined the latest drilling wells data,we analyzed the sedimentary and stratigraphic characterization of the mixed strata via detailed field outcrops and core observations and thin section microscopic observations and recognized three depositional systems,including progradational coastal system,incised valley system,and carbonate-dominated marine shelf system,and identified four third-order sequences,SQ1,SQ2,SQ3 and SQ4,consisting of LST,TST,and HST.The depositional environment is overall belonged to marine-continental transition context and shifted from marine to continental environment frequently,showing an evolutionary pattern from marine towards terrestrial-marine transition and then back into the marine environment again in the long-term,which was controlled by the regional tectonic subsidence and the high-frequency and large-amplitude sea-level changes due to the Late Paleozoic glacial activity.The result is of significance in understanding the evolution of the Qinghai-Tibet Plateau and the sedimentation-climate response.

Mechanism of the Effect of Bacillus coagulans on Production Performance of Laying Hens in Late Laying Period

[Objective]The paper was to investigate the mechanism of Bacillus coagulans preparation in improving production performance of laying hens in late period of laying.[Method]A total of 648 individuals of"Jingfen 1"laying hens(66 weeks of age)in late period of laying were randomly divided into four groups,six replicates each group,and each group had 27 individuals of laying hens.The laying hens in control group were fed with basal diet,and those in experimental groupsⅠ,Ⅱ and Ⅲ were fed with the basal diets added with 3.33×10^6,1×10^7,3.33×10^7 CFU/g B.coagulans,respectively.The pretrial lasted one week,and the formal test lasted eight weeks.[Result]Compared with the control group,the laying rate in group Ⅰ increased significantly,and the feed-gain ratio in experimental group Ⅱ decreased noticeably while the spleen index increased remarkably;the alkaline phosphatase activities and blood calcium content in experimental groups Ⅰ,Ⅱ and Ⅲ increased significantly(P<0.05),while the triglyceride content decreased remarkably(P<0.05);the urea content in experimental groups Ⅰ and Ⅱ decreased obviously(P<0.05).Adding B.coagulans significantly increased the specific activity of amylase,lipase and protease in various intestinal mucosa of small intestine(P<0.05);adding B.coagulans significantly increased the content of follicle-stimulating hormone(FSH)and estradiol(E2),and significantly increased the mRNA expression of follicle stimulating hormone receptor gene(FSHR).[Conclusion]B.coagulans preparation could significantly improve the production performance of laying hens in late period of laying;appropriately enhance the immune capacity of laying hens;improve the serum biochemical indicators;increase the activity of digestive enzymes in the small intestine;and promote the release of gonadal hormone and the mRNA expression of FSHR gene in the ovary.

Effects of Xylooligosaccharide(XOS)and Probiotics(PRO)on Production Performance,Egg Quality and Intestinal Short-chain Fatty Acids of Laying Hens in Late Laying Period

[Objective]The paper was to study the effects of xylooligosaccharide(XOS)and probiotics(PRO)and their interaction on the production performance,egg quality and intestinal short-chain fatty acids of laying hens in late laying period.[Method]A total of 36074-week-old Romain brown laying hens were randomly divided into four groups,six replicates each group and 15 chickens each replicate.The trial lasted 63 d.The laying hens in control group(CON)were fed with basal diet,and those in experimental groups were fed with the basal diets adding with 150 mg/kg XOS(XOS group),100 mg/kg probiotics(PRO group),150 mg/kg XOS+100 mg/kg probiotics(XOS-PRO group).[Result]Compared with the control group,the laying rate,daily egg production,yolk ratio,colonic acetic acid and caecal propionic acid in XOS group increased significantly(P<0.05),and the feed gain ratio decreased remarkably(P<0.05).PRO had no significant effect on the production performance and egg quality of laying hens in late laying period(P>0.05),but significantly increased colonic acetic acid(P<0.05).XOS and PRO had no interaction effect on the production performance,egg quality and intestinal short-chain fatty acids of laying hens in late laying period(P<0.05).[Conclusion]Adding XOS to the diet of laying hens in late laying period could increase the content of short-chain fatty acids in the hindgut of laying hens,and effectively improve the production performance and egg quality of laying hens in late laying period.Adding PRO to the diet did not significantly improve the production performance and egg quality of laying hens,and there was no interaction effect between XOS and PRO.

Social development and living environment changes in the Northeast Tibetan Plateau and contiguous regions during the late prehistoric period

The relationship between the evolution of human societies and their living environments has been discussed intensively in recent decades.It is important to understand the patterns and mechanisms of human–environment interaction and evolution in order to cope with rapidly changing environments in the modern world.We reviewed the results of dating,archaeobotanical,and zooarchaeological studies from 139 prehistoric sites in the Northeast Tibetan Plateau(NETP)and contiguous regions(NETP-CR:i.e.,the Hexi Corridor and western margin of the Chinese Loess Plateau)and compared them with paleoenvironmental records to study variations in spatiotemporal patterns of social development in the area and their relationships with climate and vegetation changes.Our results show that hunter-gatherer groups occupied vast areas of the NETP at low intensities during^15,000–5500 BP(years before present).This was directly related to forest cover and climate change.An increase in temperature and precipitation turnover of vegetation from desert steppe to alpine meadow/subalpine shrub,and recovery of animal population on the Tibetan Plateau created more food resources and space for hunter-gatherers.Millet farmers settled extensively below 2500 m a.s.l.(meters above sea level)in the NETP-CR between^5500 and 3600 BP,and might have coexisted with hunting groups above 2500 m a.s.l.via subsistence exchange.The distribution of human settlements during that period was affected by climate change,with the relatively warm and wet climate promoting the expansion of millet agriculture to the NETP-CR during 5500–4500 BP,while climate deterioration caused humans to retreat to lower altitudes.During 3600–2200 BP,a range of livelihoods emerged in different regions of the NETPCR.This was promoted by early trans-Eurasian exchange and the development of an agro-pastoral economy that utilized cold-tolerant crops and livestock.This eventually promoted the expansion of permanent human settlements to high-altitude areas in the NETP.This study found that human societies adopted various strategies to adapt to the changing living environment throughout late prehistoric times in the NETP-CR.The results provide a long-term perspective on the trajectory of regional socio-environmental co-evolution.

CHINESE LADY'S DAILY WEAR IN LATE QING DYNASTY AND EARLY REPUBLIC PERIOD

The goal of this research is to describe and analyze women’s wear in the late Qing Dynasty andearly Republic Period(late 19th c.—early 20th c.),with an emphasis on the daily informal orsemi-formal wear,though some formal or ceremonial costumes such as wedding dress will also beincluded.This study will use Chinese costumes and textiles from many museums to fill in theblanks left by previous research and to give a more detailed and accurate description.It will alsouse historical documents to find the original names of these items and to illustrate a general conceptof their usage on different occasions.The different categories of women’s wear will be described in the following order:①robes orcoats;②jackets;③waistcoats or vests;④skirts;⑤pants and leggings;⑥shoes and socks;⑦headdresses;and⑧others.Of every category,the textiles,decoration,cut,form,style,colourand motif will be discussed.The way in which these items were combined will also be discussed.The comparison between women’s wear and men’s wear,women’s and children’s informal andformal dress will be given.Here are some tentative conclusions.First,the Manchu and Han style coexisted and mixedwith each other and were worn by both Manchu and Han women.Second,the basic silhouettesand cuts were relatively stable and conventional,while the decorations and details(openings,fasten-ings,pleats,vents,collars and hemlines)were different.The former represented accepted socialstandards while the latter could be a matter of personal taste.Third,women’s wear in that periodwere highly stylized,miscellaneous,elaborate,detailed,multicolored and multi-thematic.

极端涝害条件下晚播对超强筋小麦济麦44产量与品质的影响

2021年度,山东发生极端涝害,小麦播期整体延迟。本研究以超强筋小麦济麦44为材料,设置5个播期,分析极端涝害条件下不同播期对济麦44产量和品质性状的影响。结果表明:冬前分蘖随播期推迟而明显减少;产量随播期推迟而降低,W_(1)处理(10月25日播种)的最高,为8359.05 kg/hm^(2);穗粒数随播期推迟整体呈减少趋势;单位面积穗数和千粒重整体均呈先增加后减少趋势,W_(1)、W_(2)处理(11月5日播种)显著高于其他处理。W_(3)处理(11月15日播种)小麦籽粒各项品质指标整体较好;产量最高时(W_(1)),籽粒中各矿质元素含量均最低;籽粒品质较好时(W_(3)),各矿质元素含量相对也较高,尤其是K、Na、Zn、Se、Cu的含量均最高。综上得出,如遇极端天气,鲁中地区超强筋小麦济麦44的播期控制在11月15日之前时,晚播对其产量和品质的影响较小,可实现一定程度上的优质高产,并且对矿质元素含量的影响较小。

药隔期倒春寒对小麦根际细菌群落结构的影响

以抗倒春寒性强的小麦品种烟农19(YN)和抗倒春寒性弱的小麦品种新麦26(XM)为实验材料,于小麦幼穗分化的药隔形成期利用智能超低温培养箱进行4℃(T1)和-4℃(T2)低温胁迫处理,以15℃作为对照(CK),利用高通量测序技术对开花期小麦根际土壤细菌群落进行测定,研究药隔期倒春寒对小麦根际细菌多样性和群落结构的影响。结果表明:(1)倒春寒危害后两品种小麦根际土壤细菌的ACE指数较CK均有所降低,且对抗倒春寒性弱的品种XM影响显著(P<0.05)。(2)两品种小麦根际土壤细菌群落主要由变形菌门(53.20%~57.55%)、放线菌门(13.34%~21.69%)、拟杆菌门(10.56%~12.37%)和芽单胞菌门(6.17%~9.19%)等33个门及819个属的细菌组成,且不同程度倒春寒处理间各菌门相对丰度表现出差异性,其中放线菌门(Actinobacteria)相对丰度在YN中升高9.79%~19.11%,在XM中降低26.43%~38.47%。(3)根际土壤细菌功能预测分析显示,药隔期倒春寒提高了膜运输、氨基酸代谢、碳水化合物代谢、复制与修复功能基因在YN根际土壤中的相对丰度,降低了其在XM根际土壤中的相对丰度。综上所述,药隔期倒春寒降低了小麦根际土壤细菌群落的丰富度,改变了细菌群落结构,影响了细菌群落的膜运输、氨基酸代谢、碳水化合物代谢和复制与修复功能。

从儒家经典到课本选文:清末民初读经科向国文科的转化与融入

民国初年读经被取消后又被反复提倡,但清末的读经科部分转化、融入了国文科并影响了国文科的发展:国文科课程目标中的“德”由读经科转入,教材中部分课文是对读经科中的整本儒家经典的节选,教学中的诵读法也来自读经科。转化的发生及其成功,主要原因是:读经科改变了形式,顺应了现代教育(国文)的变化,教育目的由培养臣民转为培养公民,教育形式由私塾中的单个点拨到学堂中的班级授课,国文教材形态由专书变为选文,考试文体由八股变为古文。

僧诗总集与晚明清初的丛林习诗热潮——以稀见文献《珠林风雅》为典型

《珠林风雅》是晚明清初僧诗风气高涨的产物,也是古典诗歌总集编印高潮时期的典型样本。它生动地反映了诗歌从个别精英僧人的专利,到清初发展为一般文化僧都能够参与的文学活动。这是明清之际诗学家徐增编选的僧诗总集,以寺院为中心,选录了灵隐寺住持晦山戒显及僧众十余人的诗作一百余首。戒显入选最多,其中的《题武昌黄鹤楼》不仅当时“天下传颂”,而且逐渐流传为两种版本。版本差异显现了清代政治规训力量的强悍,也显现了僧诗在诗坛的影响。其他僧人也大半编有自己的诗集,但对入选仍极为热心,他们不仅期待借助传播性更强的诗歌总集传世不朽,也希望跻身为寺院文化的塑造者。晚明清初僧诗文献大量存世,无论种类还是数量都已远远超过前代,却很少受到学界关注。这一存世文献与研究成果极不对应的现象,提醒研究者重新审视佛教文学史的认识框架。

慢熟的土地:清末到民国的云南话剧文学(1913—1949年)

云南话剧文学的发展起步很早,经历了从萌芽到潮起、寂寞呐喊和学步模仿再到激情怒火中的爆发几个阶段,有学生的集体创作,也有个人的苦闷绝叫,还有时代催生的民族激情,更有民主大潮中的社会呐喊。云南话剧文学创作演出的构成分为本土剧作家的本土创作演出和外来剧作家在云南的“在地”创作演出。在这一时期里,云南现代话剧文学创作蹒跚地走向初步成型,耕耘中,远远守望着姗姗来迟的成熟。

晚清民国报刊《滕王阁序》拟作考论

晚清民国时期,中国效仿西法兴办报刊,不但刊发时评政论、世界大事、商业广告,也刊载文人创作的旧体文学。骈文也有不少篇目见刊,但大都不是原创,而是对经典篇目的模拟和戏仿。其中仿王勃《滕王阁序》的拟作最具代表性,虽然这些拟作在艺术上未有突破和创新,但其书写新的时代,关注新的题旨,批判不良现象,对传统旧体文学的表达空间有所拓展,具有较高的社会认识价值和文献史料意义。

论清末民初博览会事业中的民族主义

清末民初博览会事业蕴涵了丰富的民族主义。它产生的外部因素是西方“先进”所形成的“榜样”力量,以及西方帝国的霸权行径和经济侵略,内部因素是中国自身的落后,以及中国人所具有的“经世忧国”传统精神。它产生的路径基本是:先进的西方列强,对落后中国进行经济侵略,导致中国利权外溢,产生严重民族危机,具有“经世忧国”精神的中国人奋发图强,既积极学习西方,仿行西法,又反省自身落后,积极展开竞争,谋求改良、发展,其中,蕴涵了忧患、危机、反省意识及竞争、发展观念,最终目的是实现民族国家独立富强。这样的民族主义具有追赶性、内向性、开放性特征,且主要体现在经济层面,虽有过急追求发展的一面,但其价值目标及立足自身的方法取向是理性的。

从侵略到保全:佐藤信渊思想转变及其实质——以《存华挫狄论》为中心

江户中期,日本通过与荷兰等欧洲国家的接触,视野渐趋朝向西方,对中华文化的崇拜感有所减弱。江户后期,日本人开始贬低清朝,抛弃以中国为中心的“华夷秩序”,甚至提出了“侵略清朝论”。然而,从佐藤信渊的《存华挫狄论》可以看出,鸦片战争后他对中国的态度由征服清朝转向了保全清朝。佐藤信渊在《存华挫狄论》中所指出的清朝应对鸦片侵略中的十六次“失策”存在误解,“保全清朝论”的实质是借助清朝遏制西方列强的侵略态势,进而维护日本自身利益。

晚清使臣西洋观剧再考

晚清使臣和他们的随员在西洋“看戏”,实为中国人较早接触西方文学的重要史实。因缺乏语言能力或文化基础,他们的观剧录往往成为令人费解的“天书”,因之被学界长期忽略。运用国外电子文献数据库综合考析,可知晚清使臣李凤苞所观西洋剧为《睡美人》,张荫桓所观为《迷娘》《不可告人》《科西嘉弟兄》等三部剧,张德彝所观为《地狱中的俄耳甫斯》《恶魔》《新欢旧爱》《罗蕾莱》《穷汉乔纳森》《圣女贞德》《蚱蜢的报复》等七部剧。这些事实的揭出,可以补足19世纪中西文学关系史中缺位的中国人面向,富有学术价值与意义。
