Lithofacies Palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China
Journal of Palaeogeography 2014, 3(4): 384-409 DOI: 10.3724/SP.J.1261.2014.00063 Lithofacies palaeogeography and sedimentology Lithofacies palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China Jin-Xiong Luo*, You-Bin He, Rui Wang School of Geosciences, Yangtze University, Wuhan 430100, China Abstract The lithofacies palaeogeography of the Late Permian Wujiaping Age in Middle and Upper Yangtze Region was studied based on petrography and the “single factor analysis and multifactor comprehensive mapping” method. The Upper Permian Wujiaping Stage in the Middle and Upper Yangtze Region is mainly composed of carbonate rocks and clastic rocks, with lesser amounts of siliceous rocks, pyroclastic rocks, volcanic rocks and coal. The rocks can be divided into three types, including clastic rock, clastic rock-limestone and lime- stone-siliceous rock, and four fundamental ecological types and four fossil assemblages are recognized in the Wujiaping Stage. Based on a petrological and palaeoecological study, six single factors were selected, namely, thickness (m), content (%) of marine rocks, content (%) of shallow water carbonate rocks, content (%) of biograins with limemud, content (%) of thin- bedded siliceous rocks and content (%) of deep water sedimentary rocks. Six single factors maps of the Wujiaping Stage and one lithofacies palaeogeography map of the Wujiaping Age were composed. Palaeogeographic units from west to east include an eroded area, an alluvial plain, a clastic rock platform, a carbonate rock platform where biocrowds developed, a slope and a basin. In addition, a clastic rock platform exists in the southeast of the study area. Hydro- carbon source rock and reservoir conditions were preliminarily analyzed based on lithofacies palaeogeography. -
A Qualitative and Comprehensive Analysis of Caries Susceptibility for Dental Fluorosis Patients
antibiotics Review A Qualitative and Comprehensive Analysis of Caries Susceptibility for Dental Fluorosis Patients Qianrui Li 1 , Jiaqi Shen 1, Tao Qin 1, Ge Zhou 1, Yifeng Li 1, Zhu Chen 2 and Mingyun Li 1,* 1 State Key Laboratory of Oral Diseases, National Clinical Research Center for Oral Diseases, West China School of Stomatology, Sichuan University, Chengdu 610041, China; [email protected] (Q.L.); [email protected] (J.S.); [email protected] (T.Q.); [email protected] (G.Z.); [email protected] (Y.L.) 2 Key Laboratory of Oral Disease Research, School of Stomatology, Zunyi Medical University, Zunyi 563000, China; [email protected] * Correspondence: [email protected] Abstract: Dental fluorosis (DF) is an endemic disease caused by excessive fluoride exposure during childhood. Previous studies mainly focused on the acid resistance of fluorotic enamel and failed to reach a consensus on the topic of the caries susceptibility of DF patients. In this review, we discuss the role of DF classification in assessing this susceptibility and follow the “four factors theory” in weighing the pros and cons of DF classification in terms of host factor (dental enamel and saliva), food factor, bacteria factor, and DF treatment factor. From our analysis, we find that susceptibility is possibly determined by various factors such as the extent of structural and chemical changes in fluorotic enamel, eating habits, fluoride levels in diets and in the oral cavity, changes in quantity and quality of saliva, and/or oral hygiene. Thus, a universal conclusion regarding caries susceptibility might not exist, instead depending on each individual’s situation. -

Mercury Accumulation in Vegetable Houttuynia Cordata Thunb. from Two
www.nature.com/scientificreports OPEN Mercury accumulation in vegetable Houttuynia cordata Thunb. from two diferent geological areas in southwest China and implications for human consumption Qingfeng Wang1,2*, Zhonggen Li1,2, Xinbin Feng2, Ao Wang4, Xinyu Li2,3, Dan Wang1 & Leilei Fan1 Houttuynia cordata Thunb. (HCT) is a common vegetable native to southwest China, and grown for consumption. The results suggested that THg contents in all parts and MeHg in underground parts of HCT in Hg mining areas were much higher than those in non-Hg mining areas. The highest THg and MeHg content of HCT were found in the roots, followed by the other tissues in the sequence: roots > leaves > rhizomes > aboveground stems (THg), and roots > rhizomes > aboveground stems > leaves (MeHg). The average THg bioaccumulation factor (BCF) of HCT root in the Hg mining area and in non-Hg mining areas could reach 1.02 ± 0.71 and 0.99 ± 0.71 respectively, indicating that HCT is a Hg accumulator. And the THg and MeHg contents in all tissues of HCT, including the leaves, were signifcantly correlated with THg and MeHg content in the soil. Additionally, preferred dietary habits of HCT consumption could directly afect the Hg exposure risk. Consuming the aboveground parts (CAP) of HCT potentially poses a high THg exposure risk and consuming the underground parts (CUP) may lead to a relatively high MeHg exposure risk. Only consuming the rhizomes (OCR) of the underground parts could signifcantly reduce the exposure risk of THg and to some extent of MeHg. In summary, HCT should not be cultivated near the Hg contaminated sites, such as Hg tailings, as it is associated with a greater risk of Hg exposure and high root Hg levels, and the roots should be removed before consumption to reduce the Hg risk. -

Rosen Received: 17 May 2016; Accepted: 24 August 2016; Published: 29 August 2016 Abstract: A scientific definition of the type of mountain area and an exploration of the spatial correlation between different types of mountain areas and regional land use at the county level are important for reasonable land resource utilization and regional sustainable development. Here, a geographic information system was used to analyze digital elevation model data and to define the extent of mountainous land and types of mountain areas in Guizhou province. Exploratory spatial data analysis was used to study the spatial coupling relation between the type of mountain area and land use degree in Guizhou province at the county level. The results were as follows: (1) Guizhou province has a high proportion of mountainous land, with a ratio of mountainous land to non-mountainous land of 88:11. The county-level administrative units in Guizhou province were exclusively mountainous, consisting of eight semi mountainous counties, nine quasi mountainous counties, 35 apparently mountainous counties, 13 type I completely mountainous counties, and 23 type II completely mountainous counties; (2) The land use degree at the county level in Guizhou province have remarkable spatial differentiation characteristics. -

It is the only major tributary of the Upper Yangtze that remains free-flowing without a mainstream dam. The Chishui River Basin (CRB) is an important storehouse of biodiversity, lying within the Upper Yangtze Freshwater Ecoregion and the Guizhou Plateau Broadleaf and Mixed Forests Terrestrial Ecoregion. The basin also lies on the eastern margin of the Mountains of Southwest China biodiversity hotspot, and contains part of the China Danxia World Heritage Site. -
For Personal Use Only Use Personal for a Loan That Mr Zhang Claimed Had Been Guaranteed by PRC DSX
5 May 2017 Elizabeth Harris Principal Advisor ASX Listing Compliance Level 40, Central Park 152-158 St Georges Terrace PERTH WA 6000 Dear Ms Harris ASX Query: Ding Sheng Xin Finance Co. Limited We refer to your letter dated 24 April 2017 in which you have sought a response from the Company in relation to questions raised by the ASX regarding judgements made involving the Company’s subsidiary (“PRC DSX”) in the People’s Republic of China. In response to ASX’s queries, the Company advises as follows: 1. It is a natural consequence of the nature of PRC DSX business, being guaranteeing the repayment of loans and other specific performances, that it will be involved in legal processes. Where lenders seek recovery of loans following any default of the performance of borrowers, and that borrower is a client of PRC DSX and their repayment obligations are guaranteed by PRC DSX, PRC DSX will be named in the relevant legal processes. Accordingly, PRC DSX has been and is likely to continue to be a party to legal processes and by extension to have judgements made against it in its capacity as guarantor. PRC DSX processes are such that if a client defaults and a judgement is made against that client, and by extension PRC DSX, PRC DSX then seeks to renegotiate the terms of the obligation on behalf of the client. If that process is successful the judgement is no longer relevant and is withdrawn, however if that process is not successful PRC DSX makes the payments on behalf of the client and proceeds to seek recovery from the client. -
