We present the findings of a United Nations Development Programme-World Health Organization study commissioned by China's Ministry of Health on use of public and private ambulatory care services in three Chinese provinces. We found much unmet medical need (16 percent), attributed mainly to the perceived high cost of care. Seventy-one percent had no health(More)
This paper reports on a questionnaire survey and 12 focus groups conducted among doctors in three provinces of China, namely Guangdong, Shanxi, and Sichuan. The survey (N = 720) and focus group participants were drawn from both rural and urban areas, as well as public and private sectors, in equal numbers The aim was to gauge how Chinese doctors feel about(More)
Biochar-modified polyacrylate-like polymers are promising waterborne polymer-based membrane coatings for controlled-release fertilizers. However, the effect of these membrane polymers on paddy soil is unknown. A soil incubation experiment was conducted using Fourier transform infrared photoacoustic spectroscopy to monitor the changes in the polymer-coated(More)
In response to addressing potassium (K) deficiency in soil and decreasing agricultural production costs, the potential of K-bearing phyllosilicate minerals that can be directly used as an alternative K source has been investigated using sodium tetraphenylboron (NaTPB) extraction and an intensive cropping experiment. The results showed that the critical(More)
The catalytic asymmetric alkylation of the remote, unactivated δ-position of N-alkyl amides was enabled by the combination of visible-light-induced proton-coupled electron transfer, 1,5-hydrogen atom transfer, and chiral Lewis acid catalysis in up to 82% yield and up to 97% ee.
Phosphorus (P) fractionation and sorption behavior as well as the abundance and community composition of phosphorus-solubilizing bacteria (PSB) in sediments, including inorganic phosphate-solubilizing bacteria (IPB) and organic phosphate-mineralizing bacteria (OPB), were investigated in 27 sampling sites of five sections in the Three Gorges Reservoir (TGR)(More)
A new grading system for plant-available potassium (K) in soils based on K release rate from soils and plant growth indices was established. In the study, fourteen different agricultural soils from the southern subtropical to the northern temperate zones in China were analyzed by both chemical extraction methods and exhaustive cropping techniques. Based on(More)
A highly diastereo- and enantioselective synthesis of 3,3-disubstituted oxindoles bearing vicinal quaternary-tertiary carbon centers is enabled by a chiral-at-rhodium Lewis acid catalyst starting from isatin N-protected ketimines and 2-acyl imidazoles. The excellent results with 93-99% yields, diastereoselectivities of 43:1 to >200:1, and high(More)
Stromwater biofilter technology was greatly improved through adding iron-rich soil, plant detritus and eutrophic lake sediment. Significant ammonium and phosphate removal efficiencies (over 95%) in treatments with iron-rich soil were attributed to strong adsorption capability resulting in high available phosphorus (P) in media, supporting the abundance and(More)
