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)
A chiral-at-metal bis-cyclometalated iridium complex combines electrophile activation via metal coordination with nucleophile activation through hydrogen bond formation. This new bifunctional chiral Lewis acid/hydrogen-bond-mediated catalyst permits the challenging enantioselective 2-alkylation of 3-substituted indoles with α,β-unsaturated 2-acyl imidazoles(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)
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)
Controlled-release fertilizers (CRF) use a controlled-release technology to enhance the nutrient use efficiency of crops. Many factors affect the release of nutrients from the waterborne polymer-coated CRF, but the effects of thermal post-treatments remain unclear. In this study, a waterborne polyacrylate-coated CRF was post-treated at different(More)
The purpose of this study was to describe the prescription of antibacterial agents for acute upper respiratory tract infections (URIs) in Beijing. A total of 8,588,699 outpatient cases in tertiary hospitals with acute upper respiratory tract infections (URIs) were selected from the Beijing Medical Claim Data for Employees (BMCDE) from Oct 2010 to Sep 2012.(More)
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)
