| 1 | Impact of Land-Use Change on Soil Microbial Community Composition and Organic Carbon Content in the Dry Tropics显示文摘Restoration of forests poses a major challenge globally, particularly in the tropics, as the forests in these regions are more vulnerable to land-use change. We studied land-use change from natural forest(NF) to degraded forest(DF), and subsequently to either Jatropha curcas plantation(JP) or agroecosystem(AG), in the dry tropics of Uttar Pradesh, India, with respect to its impacts on soil microbial community composition as indicated by phospholipid fatty acid(PLFA) biomarkers and soil organic carbon(SOC) content. The trend of bacterial PLFAs across all land-use types was in the order: NF > JP > DF> AG. In NF, there was dominance of gram-negative bacterial(G^-) PLFAs over the corresponding gram-positive bacterial(G^+) PLFAs. The levels of G^- PLFAs in AG and JP differed significantly from those in DF, whereas those of G^+ PLFAs were relatively similar in these three land-use types. Fungal PLFAs,however, followed a different trend: NF > JP > DF = AG. Total PLFAs, fungal/bacterial(F/B) PLFA ratio, and SOC content followed trends similar to that of bacterial PLFAs. Across all land-use types, there were strong positive relationships between SOC content and G-, bacterial, fungal, and total microbial PLFAs and F/B PLFA ratio. Compared with bacterial PLFAs, fungal PLFAs appeared to be more responsive to land-use change. The F/B PLFA ratio, fungal PLFAs, and bacterial PLFAs explained 91%, 94%,and 73% of the variability in SOC content, respectively. The higher F/B PLFA ratio in JP favored more soil C storage, leading to faster ecosystem recovery compared to either AG or DF. The F/B PLFA ratio could be used as an early indicator of ecosystem recovery in response to disturbance, particularly in relation to land-use change. | Chandra Mohan KUMAR Nandita GHOSHAL | 2017 | Pedosphere2017,27,5: | 5 |
| 2 | 利用卫星遥感和GIS技术测定印度切蒂斯格尔地区干旱热带森林的土地利用、生物量和碳贮量(英文)显示文摘2001-2002年间,利用卫星遥感和GIS技术研究印度切蒂斯格尔邦的赖布尔地区干旱热带森林的土地利用、生物量和碳贮量情况。主要森林类型为:柚木森林、混合林、衰退森林和婆罗双树混交林。在这些不同森林类型中,立地的坡度和坡面影响森林植被类型、生物量和碳贮量。不同森林类型中,木材积蓄积量、生物量和碳贮量的变化范围分别为:35.59~64.31 m3·hm-2、45.94~78.31Mg·hm-2和22.97~33.27Mg·hm-2。混合林中每公顷的木材蓄积量、生物量和碳贮量最大,衰退森林中的最低。混合林、柚木森林、衰退森林和婆罗双树混交林的总碳量分别为8170.72 Mg、81656.91 Mg、7833.23 Mg和7470.45 Mg。蒂斯格尔邦地区干旱热带森林处于不成熟的生长阶段,且具有很强的碳回收潜力。图6表7参49。 | Arvind Bijalwan S.L.Swamy Chandra Mohan Sharma Neeraj Kumar Sharma A.K.Tiwari | 2010 | Journal of Forestry Research2010,21,2: | 3 |
| 3 | Application of hopcalite catalyst for controlling carbon monoxide emission at cold-start emission conditions显示文摘Carbon monoxide(CO) is a poisonous gas particularly to all leaving being present in the atmosphere.An estimate has shown that the vehicular exhaust contributes the largest source of CO pollution in developed countries.Due to the exponentially increasing number of automobile vehicles on roads,CO concentrations have reached an alarming level in urban areas.To control this vehicular exhaust pollution,the end-of-pipe-technology using catalytic converters is recommended.The catalysts operating efficiently in a catalytic converter are a challenging class of materials for applications in cold start of engines to maintain indoor air quality.In the cold start period,the catalytic converter was entirely inactive,because the catalytic converter had not been warmed up.The cold start phase is also depending upon the characteristics of vehicles and property of catalysts.The increasing cost of noble metals with the increasing number of vehicles motivates the investigation of material concepts to reduce the precious metal content in automotive catalysts or to find a substitute for noble metals.Hopcalite(CuMnOx) catalyst could work very well at the low temperature;thus,it can overcome the problem of cold-start emissions if used in a catalytic converter.Further,low cost,easy availability and advanced synthesis methods with stabilizer,promoter,etc.,advocates for the use of hopcalite as an auto exhaust purification catalyst.Although there are numerous research articles present on this topic until now,no review has been presented for demanding this issue.So there is a space in this area,and it has been made an attempt to seal this hole and progress the future scope for hopcalite catalyst for purification of exhaust gases by this review. | Subhashish Dey Ganesh Chandra Dhal Devendra Mohan Ram Prasad | 2019 | Journal of Traffic and Transportation Engineering(English Edition)2019,6,5: | 3 |
| 4 | 浸泡和冷预处理对喜马拉雅长叶松不同种源种子萌发的作用(英文)显示文摘对喜马拉雅长叶松种子进行24小时GA3和H2O2浸泡预处理和15d的2-3℃低温预处理后,研究了在20℃,25℃和30℃萌发条件下,21个不同种源的喜马拉雅长叶松种子的萌发情况。结果表明,H2O2(1%v/v)和GA3(10mg/L)浸泡预处理,种子萌发率分别是82.39%和78.19%,而未经预处理的种子平均萌发率为70.79%。GA3和H2O2浸泡预处理分别使种子萌发时间缩短了8d和10d。在超过21天的20℃萌发条件下,湿冷处理提高了种子萌发率和缩短了萌发时间;而在25℃和30℃萌发条件下,总的萌发率未受到影响。喜马拉雅长叶松种子因缺少休眠而表现出很好的萌发,但是因为越来越多的造林项目需要大量的种子,播种预处理有利于提高种子萌发率和萌发速率,有助于满足种子需求。 | Sunil Kumar Ghildiyal Chandra Mohan Sharma Vinod Prasad Khanduri | 2009 | Journal of Forestry Research2009,20,4: | 3 |

| 16 | Feasibility and efficacy of delayed pharmacoinvasive therapy for STelevation myocardial infarction显示文摘BACKGROUND ST-elevation myocardial infarction(STEMI)refers to a clinical syndrome that features symptoms of myocardial ischemia with consequent ST-elevation on electrocardiography and an associated rise in cardiac biomarkers.Rapid restoration of brisk flow in the coronary vasculature is critical in reducing mortality and morbidity.In patients with STEMI who could not receive primary percutaneous coronary intervention(PCI)on time,pharmacoinvasive strategy(thrombolysis followed by timely PCI within 3-24 h of its initiation)is an effective option.AIM To analyze the role of delayed pharmacoinvasive strategy in the window period of 24-72 h after thrombolysis.METHODS This was a physician-initiated,single-center prospective registry between January 2017 and July 2017 which enrolled 337 acute STEMI patients with partially occluded coronary arteries.Patients received routine pharmacoinvasive therapy(PCI within 3-24 h of thrombolysis)in one group and delayed pharmacoinvasive therapy(PCI within 24-72 h of thrombolysis)in another group.The primary endpoint was major adverse cardiac and cerebrovascular events(MACCE)within 30 d of the procedure.The secondary endpoints included major bleeding as defined by Bleeding Academic Research Consortium classification,angina,and dyspnea within 30 d.RESULTS The mean age in the two groups was comparable(55.1±10.1 years vs 54.2±10.5 years,P=0.426).Diabetes was present among 20.2%and 22.1%of patients in the routine and delayed groups,respectively.Smoking rate was 54.6%and 55.8%in the routine and delayed groups,respectively.Thrombolysis was initiated within 6 h of onset of symptoms in both groups(P=0.125).The mean time from thrombolysis to PCI in the routine and delayed groups was 16.9±5.3 h and 44.1±14.7 h,respectively.No significant difference was found for the occurrence of measured clinical outcomes in the two groups within 30 d(8.7%vs 12.9%,P=0.152).Univariate analysis of demographic characteristics and risk factors for patients who reported MACCE in the two groups did not demonstrate any significant correlation.Secondary endpoints such as angina,dyspnea,and major bleeding were non-significantly different between the two groups.CONCLUSION Delayed PCI pharmacoinvasive strategy in a critical diseased but not completely occluded artery beyond 24 h in patients who have been timely thrombolyzed seems a reasonable strategy. | Rishi Sethi Lalit Mohan Pravesh Vishwakarma Abhishek Singh Swati Sharma Monika Bhandari Ayush Shukla Akhil Sharma Gaurav Chaudhary Akshyaya Pradhan Sharad Chandra Varun Shankar Narain Sudhanshu Kumar Dwivedi | 2023 | World Journal of Cardiology2023,15,1: | 1 |
