5Evaluating Conservation Effectiveness of Nature Reserves Established for Surrogate Species:Case of a Giant Panda Nature Reserve in Qinling Mountains,China显示文摘Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable.In this study,this effectiveness was evaluated in a nature reserve network located in the Qinling Mountains,Shaanxi Province,China.The network of reserves was established mainly for the conservation of the giant panda,a species considered as a surrogate for the conservation of many other endangered species in the region.The habitat suitability of nine protected species,including the giant panda,was modeled by using Maximum Entropy(MAXENT)and their spatial congruence was analyzed.Habitat suitability of these species was also overlapped with nature reserve boundaries and their management zones(i.e.,core,buffer and experimental zones).Results show that in general the habitat of the giant panda constitutes a reasonable surrogate of the habitat of other protected species,and giant panda reserves protect a relatively high proportion of the habitat of other protected species.Therefore,giant panda habitat conservation also allows the conservation of the habitat of other protected species in the region.However,a large area of suitable habitat was excluded from the nature reserve network.In addition,four species exhibited a low proportion of highly suitable habitat inside the core zones of nature reserves.It suggests that a high proportion of suitable habitat of protected species not targeted for conservation is located in the experimental and buffer zones,thus,is being affected by human activities.To increase their conservation effectiveness,nature reserves and their management zones need to be re-examined in order to include suitable habitat of more endangered species.The procedures described in this study can be easily implemented for the conservation of many endangered species not only in China but in many other parts of the world.XU Weihua Andrés VIA QI Zengxiang OUYANG Zhiyun LIU Jianguo LIU Wei WAN Hui 2014Chinese Geographical Science2014,24,1:12
6Self-reaction of initial active groups in coal显示文摘For further understanding of self-heating of coal,we tested the reactions of seven different ranks of coal under inert atmosphere.In the test,50-gram of coal sample ranged from 0.18 mm to 0.38 mm was put into a special designed copper reaction vessel and let pure nitrogen to flow into the coal sample from the bottom at a rate of 100 mL/min.The programmed temperature enclosure was run at a programmed rate of 0.8 °C/min.The concentration of the carbon oxides and the coal temperature were tested.The results show that the coal reactions under inert atmosphere can generate CO and CO2.The reactions under inert atmosphere are affected by coal ranks,initial pore structure of coal and sulfur content.For low ranks of coal,the productions of carbon oxides are piecewise.The coal temperature is lower than the surrounding temperature throughout the reactions under inert atmosphere,but it rises quickly and reaches a crossing point temperature in the later stage under dry-air atmosphere.Based on the analysis,it indicates the self-reaction of initial active groups exists in the self-heating of coal besides the reactions in the two parallel reactions model.Spontaneous combustion of coal is due to both the oxidation heat accumulation and the chain reaction.A new reaction model of self-heating of coal was proposed.Qi Xuyao Wang Deming James A Milke Zhong Xiaoxing 2012International Journal of Mining Science and Technology2012,22,2:6
7Consensus on the digestive endoscopic tunnel technique显示文摘With the digestive endoscopic tunnel technique(DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria(MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal(GI) tract.At present, the tunnel technique application range covers the following:(1)Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis;(2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and(3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment.The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism,and significance of DETT, prevention of infection and concepts of DETTassociated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract(indications and contraindications, procedures, pre-and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).Ning-Li Chai Hui-Kai Li En-Qiang Linghu Zhao-Shen Li Shu-Tian Zhang Yu Bao Wei-Gang Chen Philip WY Chiu Tong Dang Wei Gong Shu-Tang Han Jian-Yu Hao Shui-Xiang He Bing Hu1 Bing Hu2 Xiao-Jun Huang Yong-Hui Huang Zhen-Dong Jin Mouen A Khashab James Lau Peng Li Rui Li De-Liang Liu Hai-Feng Liu Jun Liu Xiao-Gang Liu Zhi-Guo Liu Ying-Cai Ma Gui-Yong Peng Long Rong Wei-Hong Sha Pateek Sharma Jian-Qiu Sheng Shui-Sheng Shi Dong Wan Seo Si-Yu Sun Gui-Qi Wang Wen Wang Qi Wu Hong Xu Mei-Dong Xu Ai-Ming Yang Fang Yao Hong-Gang Yu Ping-Hong Zhou Bin Zhang Xiao-Feng Zhang Ya-Qi Zhai 2019World Journal of Gastroenterology2019,25,7:5
8Influence of precipitation on the Portevin-Le Chatelier effect in Al-Mg alloys显示文摘In the alloy with solute content higher than the limiting solubility,the solute atoms that have failed to dissolve will precipitate from the solid solution and form precipitations.In this study, the Portevin-Le Chatelier(PLC) effects in annealed 5456 and 5052 aluminum alloys with different precipitation contents have been investigated under different applied strain rates.The results suggest that precipitations have significant effect on the PLC effect and the more the precipitations are, the greater the ...Qi Hu,~(a))Qingchuan Zhang,~(b)) Shihua Fu,Pengtao Cao,and Ming Gong CAS Key Laboratory of Mechanical Behavior and Design of Materials,University of Science and Technology of China,Hefei 230027,China 2011Theoretical & Applied Mechanics Letters2011,1,1:3

10Agricultural Risk Factors Influence Microbial Ecology in Honghu Lake显示文摘Agricultural activities, including stock-farming, planting industry, and fish aquaculture,can affect the physicochemical and biological characters of freshwater lakes. However, the effects of pollution producing by agricultural activities on microbial ecosystem of lakes remain unclear.Hence, in this work, we selected Honghu Lake as a typical lake that is influenced by agriculture activities. We collected water and sediment samples from 18 sites, which span a wide range of areas from impacted and less-impacted areas. We performed a geospatial analysis on the composition of microbial communities associated with physicochemical properties and antibiotic pollution of samples. The co-occurrence networks of water and sediment were also built and analyzed. Our results showed that the microbial communities of impacted and less-impacted samples of water were largely driven by the concentrations of TN, TP, NO_3^--N, and NO_2^--N, while those of sediment were affected by the concentrations of Sed-OM and Sed-TN. Antibiotics have also played important roles in shaping these microbial communities: the concentrations of oxytetracycline and tetracycline clearly reflected the variance in taxonomic diversity and predicted functional diversity between impacted and less-impacted sites in water and sediment samples, respectively. Furthermore, for samples from both water and sediment, large differences of network topology structures between impacted and less-impacted were also observed. Our results provide compelling evidence that the microbial community can be used as a sentinel of eutrophication and antibiotics pollution risk associated with agricultural activity; and that proper monitoring of this environment is vital to maintain a sustainable environment in Honghu Lake.Maozhen Han Melissa Dsouza Chunyu Zhou Hongjun Li Junqian Zhang Chaoyun Chen Qi Yao Chaofang Zhong Hao Zhou Jack A Gilbert Zhi Wang Kang Ning 2019Genomics, Proteomics & Bioinformatics2019,17,1:3
