Healthcare reforms (HR) initiated by many countries impacts on healthcare systems worldwide. Being one of fast developing countries, China launched HR in 2009. Better understanding its impact is helpful for and others further pursuit HR. Here we evaluate inpatient mortality, a proxy to quality, 43 top tertiary hospitals during this critical period. This hospital-based observational study with 8 million discharge summary reports (DSR) from Chinese 2010–2012. Using DSRs, extract the vita...
Spray sulfuric acid rain solution, nitric solution and mixed on pakchoi in the greenhouse. Strong acidic inhibits formation of nutrients cabbage. While week promote Nitric has greatest impact quality nutrition.
The natural attenuation process was studied by vadose zone simulating indoor to quantify the adsorption, biodegradation and volatilization of diesel oil. Through adsorption experiment, equilibrium time sewage fine sand 24 h, maximum theoretical adsorbance Total Petroleum Hydrocarbon (TPH) calculated 234 mg/kg. contrasts three columns, first-order kinetics equations in polluted layer half-life were established. According experiments, absorption, all played important roles, they very major...
This paper deals with the influencing factors on removal of diesel oil from by soil vapor extraction (SVE) method. A series one-dimensional column experiments were conducted to study for SVE method, included extracted flow rate,water content and concentration contaminant. The results indicated that: (1) increase rate led higher contaminant efficiency,but increment was not significant at levels;(2) moisture is 12% coarse sand elimination bigger than 1% sand;(3) index higher, time be longer,...
Geo-accumulation Index and Enrichment Factor were applied in source apportionment of Changchun atmospheric particulate matter. By mutual comparison with the results respectively, explored similarities differences. The result shows that index Factors likes Zn, Cd are more serious, meanwhile urban dust, soil wind coal dust mainly pollution sources air pollution, both methods can make a scientific evaluation to human impact atmosphere, provide an important reference for matter apportionment.
Employing quantile regression method, this paper estimated the Mincer equation of wage income Chinese rural residents. The results showed that, as quantiles increased, returns to education declined slowly at first and then made a small rise. Through comparing between male female, found that female were significantly higher than those both 10% 25% quantiles. In addition, by dividing non-farm workers into five groups based on economic nature their units, essay diversity units’ differences in...
ABSTRACT A method combining statistics and matter-element theory was proposed, to evaluate the health status of main stream Shi yang River in Gansu Province, China. The river evaluation indicators their weight values were derived, constructing an system with 4 criteria layers: ‘basin’, ‘water’, ‘biology’, ‘social service function’, encompassing 11 indicators. divided into three sections: Xi ying, Liang zhou, Min qin. fuzzy model used assess grades. weights function’ are 29, 15, 24, 32%,...
Compliance with screen time guidelines among children worldwide remains low, and there is insufficient evidence on the current prevalence in China. This study aimed to investigate of compliance under 3 years old Fujian Province, East China, identify risk factors their independent effects, develop a discrimination model for targeted interventions. A cross-sectional survey was conducted low-income families recruited from welfare programs at 96 sites both urban rural areas Face-to-face...
Study on migration and transformation rules of diesel fuels pollution by using two-dimensional plexiglass tank to simulate underground aquifers. Through regular monitoring the sampling ports in total petroleum hydrocarbon content water determine medium sand aquifer process, compute out parameters mathematical model migration. This prediction media. The results showed: highest values different used time its location is closely related distance sources, concentration rose value a short time....
Comparative experiment of 3 medium sand columns was executed to research the influence water content on natural attenuation diesel fuels contaminated vadose zone. The results showed that: lower content, stronger capacity retarding was. After a spill, average concentration TPH were 57.7 g•kg-1, 47.55 g•kg-1 and 31.95 in with different (0.66 %, 8.00 % 15.22 %). Besides, found 90 days after degradated by 38 44.62 4 initial contaminant load 0.66 %. Additionally, higher larger microbial activity...
