Objective Artemisinin is an organic compound that comes from Artemisia annua. treatment the most important and effective method for treating malaria. Bibliometric analysis was carried out to identify global research trends, hot spots, scientific frontiers, output characteristics of artemisinin 2000 2021. Methods Publications their recorded information 2021 were retrieved through Web Science Core Collection (WoSCC). Using VOSviewer Citespace, hotspots trends studies on visualized. Results A...
A trace fossil with its putative in situ maker, a redlichiid juvenile of Eoredlichia intermedia Lu, 1940 from the lower Cambrian (Series 2) Chengjiang fauna, southwestern China, is reported here. Evidence for biogenetic linkage trail to trilobite includes their close, integrated association, preservation, and consistent dimensions. Analysis Scanning Electron Microscopy further strengthens this argument. Preservation mechanism fidelity loss are considered. In light functional morphology,...
Numerical results are shown in figures and tables. The major features for the traditional stress intensity factors electric displacement factor against microcrack location angle distance of center from macrocrack tip discussed. It is that, unlike single-crack problems, mechanical loading coupled together since not only releases near-tip stresses, but also disturbs field. Furthermore, influence on strain energy release rate (MSERR) at discussed detail. found that variable nature MSERR...
The macrocrack-microcrack interaction problem in transversely isotropic piezoelectric materials is studied. microcracks near a macrocrack tip the process zone are assumed to be parallel latter, while poling direction of perpendicular cracks. Three kinds elementary solutions with different crack configurations and under loading conditions given, from which reduced system Fredholm integral equations by using pseudo-traction electric displacement method (abbreviated PTED). After solved...
Abstract From the perspective of information commonalities among firms with director interlock relationships, this study mainly investigates outcomes earnings forecasts by analysts who choose to concentrate on interlocked (analysts following both a firm and its partner in their research portfolio). Using A‐share listed Chinese Shanghai Shenzhen Stock Exchanges from 2008 2013 as samples, we empirically find that produce more accurate than do not. In additional analysis, also an concentration...
This paper examines the spatial variation of land price in Tsingtao and its contributing factors. The data include auction prices 4,244 lots 2010. Three peaks are observed Tsingtao: downtown, Laoshan Scenic Area Huangdao Area. GIS is used to measure various factors such as proximity CBD, schools, hospitals, cultural sports venues, transit stations coastline. A multivariate regression assess joint effects these
China has invested excessive amounts of fertilizer on limited farmland, which poses a threat to human health and agro-ecological environment. While plethora studies have explored how reduce the total amount chemical fertilizer, scant attention been paid use intensity (FUI). This paper aims explore driving factors for change FUI answer this question. It uses official statistics from 1997 2017, as well index decomposition analysis (IDA) Laspeyres method obtain following results. The can be...
Cable accessories are the weak link in operation of entire cable system, and SR/XLPE composite interface is most prone to accidents. In order improve electric field distribution near interface, researchers usually modify silicone rubber its mechanical properties nonlinear conductivity characteristics. this paper, according theory material percolation, modified, doped with different proportions SiO2. Then flashover characteristics SR measured. The results show that modified has an impact on...
This study examines the economic consequences of financial analysts with business group concentration (analysts covering several member firms within a group). Based on Chinese sample, we find that one firm produce less accurate earnings forecasts. However, predict more accurately. Moreover, provide superior forecasts for those when they share stronger information links. Furthermore, are likely to move bigger brokerage house after obtaining better Finally, help alleviate investors'...
The aim of this paper has been to investigate the effects Enterprise Ownership on R&D Efficiency. With China still being in transition from its central planning legacy, efficiency could be potential channels through which ownership effect productivity is transmitted. Using production frontier function, tested for a sample large and medium size Chinese industrial enterprises different sectors during 2004-2017. factors are important determinants efficiency. presence state negatively related...
This paper aims to use econometric model study the impact of ownership on enterprises technological innovation. It provides a theoretical deal with competition between public and private in The analyzing methodology falls field mixed duopoly, which is typical transitional economy. Technological innovation productivity test-Frontier function considered this research. results show that factors are important determinants strategy efficiency. Welfare-maximising will recognize value positive...
In this paper, a mixed duopoly model is used to explain how ownership structure influences the innovation performances of firms. A three stage-game adopted in study. first stage, firms make R&D expenditure which leads profit increasing; second choose level technological improvement they would like share with rival; and production quantity will be decided final stage. The theory explains that as long public continue their dual roles productive entities social safety nets, cannot purely...
This study investigates why financial analysts participate in non-covered firms’ conference calls. Consistent with the view that firms benefit from information commonalities and complementarities connected peers, we hypothesize are more likely to a firm’s calls if firm shares links covered firm. Using sample of earnings call transcripts over 2006–2014 period, find probability participating is positively associated between their firm, including same industry link, region customer-supplier...
