An Analysis of Spatio-Temporal Urbanization Patterns in Northwest China
land Article An Analysis of Spatio-Temporal Urbanization Patterns in Northwest China Haifen Lei 1,2, Jennifer Koch 2 and Hui Shi 1,* 1 School of Environmental and Municipal Engineering, Xi’an University of Architecture and Technology, Xi’an 710055, China; [email protected] 2 Department of Geography and Environmental Sustainability, The University of Oklahoma, Norman, OK 73019, USA; [email protected] * Correspondence: [email protected] Received: 6 September 2020; Accepted: 19 October 2020; Published: 27 October 2020 Abstract: Chinese metropolitan areas have been experiencing urbanization over the past decades, impacting biodiversity, carbon emissions, urban heat islands, and food security. Yet, systematic research on spatio-temporal urbanization patterns and drivers along the urban–rural gradient is rarely reported for northwest China. Here, we use land-use data from 1980 to 2015 to explore land-use change, urbanization intensity, and drivers in northwest China. Our results display direct and indirect effects of urban expansion on farmland loss, but also spatio-temporal heterogeneity in the urbanization patterns. While the earlier years were dominated by infill and land conversion close to city centers, the later years displayed sprawling urbanization following the constraints of terrain and administrative boundaries at the cost of farmland. Our regression analysis of spatial variables found a strong relationship with urban planning factors. The spatial analysis of urbanization patterns revealed indirect land-use change on former farmland. Furthermore, we found that regional geography and historic sites considerably influenced land conversion. Overall, our findings indicate the need for sustainable planning strategies that synthesize approaches to farmland and historic site protection and consideration of regionally specific landscape characteristics. -

The Systematic Review and Meta-Analysis of X-Ray Detective
Wang et al. BMC Musculoskeletal Disorders (2019) 20:78 https://doi.org/10.1186/s12891-019-2461-z RESEARCHARTICLE Open Access The systematic review and meta-analysis of X-ray detective rate of Kashin-Beck disease from 1992 to 2016 Xi Wang1,2†, Yujie Ning1†, Amin Liu1, Xin Qi1, Meidan Liu1, Pan Zhang1 and Xiong Guo1* Abstract Background: Kashin-Beck disease (KBD) is a serious human endemic chronic osteochondral disease. However, quantitative syntheses of X-ray detective rate studies for KBD are rare. We performed an initial systematic review and meta-analysis to assess the X-ray detective rate of KBD in China. Methods: For this systematic review and meta-analysis, we searched five databases (PubMed, Web of Science, Chinese National Knowledge Infrastructure (CNKI), WanFang Data and the China Science and Technology Journal Database (VIP))using a comprehensive search strategy to identify studies of KBD X-ray detective rate in China that were published from database inception to January 13, 2018. The X-ray detective rate of KBD was determined via an analysis of published studies using a random effect meta-analysis with the proportions approach. Subgroup analysis and meta- regression were used to explore heterogeneity, and study quality was assessed using the risk of bias tool. Results: A total of 53 studies involving 14,039 samples with X-ray detective rate in 163,340 observations in total were included in this meta-analysis. These studies were geographically diverse (3 endemic areas). The pooled overall X-ray detective rate for KBD was 11% (95%CI,8–15%;Z = 13.14; p < 0.001). -
Study on Urban Efficiency Measurement and Spatiotemporal
sustainability Article Study on Urban Efficiency Measurement and Spatiotemporal Evolution of Cities in Northwest China Based on the DEA–Malmquist Model Jun Yin and Qingmei Tan * College of Economics and Management, Nanjing University of Aeronautics and Astronautics, Nanjing 211106, China; [email protected] * Correspondence: [email protected] Received: 18 November 2018; Accepted: 12 January 2019; Published: 15 January 2019 Abstract: Urban efficiency can effectively measure the management and allocation level of urban factor inputs. Based on the data of 30 prefecture-level cities in Northwest China from 2006 to 2015, urban efficiency is measured by data envelopment analysis (DEA). Then the spatiotemporal evolution rule is identified by Malmquist model. The results illustrate that the overall average urban efficiency of cities in Northwest China each year from 2006 to 2015 was at the low level. Only Jiayuguan, Yulin, Yan’an, and Karamay reached the high average urban efficiency, while Dingxi, Pingliang, Guyuan, Shangluo, Tianshui, Longnan, and Baiyin were at the inefficient level. Most cities in Northwest China were still in the “growing” stage of increasing returns to scale. The scale of urban investment was relatively insufficient, and economies of scale had not yet formed. Cities with decreasing returns to scale were mainly distributed in the capital cities and the central and sub-central cities of Guanzhong-Tianshui Economic Zone with relatively abundant urban resources and capital. Cities with constant returns to scale were mainly distributed in four cities including Yan’an, Yulin, Jiayuguan, and Karamay with high efficiency. The overall comprehensive efficiency, technical efficiency, and scale efficiency of cities in Northwest China were not only low, but also showing a downward trend. -

[email protected] Arch Med Sci DOI: https://doi.org/10.5114/aoms/134059 Copyright © 2021 Termedia & Banach Abstract Introduction: The present work describes the green synthesis and charac- terization and cytotoxicity, antioxidant, and anti-human lung cancer activ- ities of silver nanoparticles containing Curcumae kwangsiensis folium leaf aqueous extract. Material and methods: Ag nanoparticles were produced by mixing the AgNO3 solution with aqueous C. kwangsiensis folium leaf extract. Charac- terization of Ag nanoparticles was done by FE-SEM, FT-IR, TEM, and UV-Vis. FE-SEM and TEM images revealed an average diameter of 15-21 nm for the nanoparticles. MTT assay was used on common human lung cancer cell lines, i.e., lung well-differentiated bronchogenic adenocarcinoma (HLC-1), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung poorly differentiated adenocarcinoma (PC-14) cell lines, to survey the cytotoxicity and anti-human lung cancer effects of Ag nanoparticles. -

Jun Xu Received: 13 May 2016; Accepted: 26 July 2016; Published: 3 August 2016 Abstract: Nitrate contamination in rivers has raised widespread concern in the world, particularly in arid/semi-arid river basins lacking qualified water. Understanding the nitrate pollution levels and sources is critical to control the nitrogen input and promote a more sustainable water management in those basins. Water samples were collected from a typical semi-arid river basin, the Weihe River watershed, China, in October 2014. Hydrochemical assessment and nitrogen isotopic measurement were used to determine the level of nitrogen compounds and identify the sources of nitrate contamination. Approximately 32.4% of the water samples exceeded the World Health Organization ´ (WHO) drinking water standard for NO3 -N. Nitrate pollution in the main stream of the Weihe 15 ´ River was obviously much more serious than in the tributaries. -
1 China Xi'an-Ankang Railway Construction Project
China Xi’an-Ankang Railway Construction Project (1)-(3) (CXVII-P73, CXVIII-P73, CXIX-P73) External Evaluator: Mitsue Mishima (OPMAC) Field Survey: October 2004 1. Project Profile and Japan’s ODA Loan Mongolia Beijing North Korea China South Korea Project site Xian Nepal Ankang Bhutan India Taiwan Myanmar Vietnam Laos Project site location map (Xian-Ankang, Shannxi Province) Qingcha Tunnel 1.1 Background The project site (Xian- Ankang) is located in the southern part of Shaanxi Province where the 3000-meter high Qinling Mountains extend over 1500 kilometers, and was therefore undeveloped due to difficulties in transportation and remoteness from cities. Southwest of the project site is Sichuan Province, the largest province with a population of 110 million accounting for 10% of the population of China. However, as there is no other transport route to Sichuan Province than taking a detour around the Qinling Mountains, there were only limited routes to transport energy and everyday commodities from the north. Railway transport from other regions to Sichuan Province depended on Baoching Line (Baoji-Chengdu) from the north and Xiangyu Line (Xiangfan-Ankang-Chongquing) from the east, and both lines were operating to full capacity. It was particularly difficult to double-track Baoching Line, which takes a detour to avoid the Qinling Mountains because of 1) long distance of transport, 2) large cost to transport on a gradient at an angel of 3%, and 3) the topographical problem. The opening of the electrified single track of Xian-Ankang Line not only helped increase the transport capacity within Shaanxi Province but also shortened the traveling distance to Chongquing and eased the transportation load on Baoching Line. -
