In this paper, we assess the effect of ecological construction in China during 2008 to 2014. The effect of ecological construction is divided into green economy, green society, and green environment. A network data envelopment analysis (DEA) is employed to measure the total level of ecological construction in China and each region. According to the results, we find that the total level of ecological...
The Qingdong area, located in Bohai bay basin, was suspected good exploration prospects. In order to study tectonic features and find out favourable petroleum prospects in the area, the gravity data at a scale of 1:50,000 were interpreted. This paper, through data processing and synthetic interpretation of the high-precision gravity data in the area, discusses characteristics of the gravity field...
Euphorbia pekinensis Rupr., which is also known as a medicinal plant, produces a large amount of alkaloids, phytosterols and triterpenes. In this study, we reported on the cDNA cloning and characterization of a novel squalene synthase (SQS) from E. pekinensis. Squalene synthase catalyzes the condensation of two molecules of farnesyl diphosphate (FPP) to produce squalene (SQ), the first committed precursor...
