As the main portion of urban catchment, road is also a major non-point pollution source of receiving water body. The road runoff pollution has attracted wide attention. The paper makes a study on six rainfall road runoff from 3 different types of roads, analyses the status of road runoff pollution, the surface runoff pollution load and correlation between road runoff pollutants. The result shows that...
In this paper, we choosed De-xing copper mine as study area, collected canopy spectral data and determined the heavy metal concentration in Comnyza Canadensis (L.) Cronq leaves. These plants in background field have significant spectral feature, such as the low reflectance, the biggest absorption valley depth and the largest red valley area. Compared with spectral feature of Comnyza Canadensis (L...
130 wet deposition events were observed at the summit of Mt. Tai (East China, 1534 a.s.l) in China during Jan. 2005 to Dec. 2008. Zn, Al, Mn, Fe, Pb, Cu, Ni, Cr, As, and Cd were determined by ICP-MS to evaluate the characteristics of heavy metals in wet deposition at Mt. Tai region. The concentrations of these metals are generally higher at Mt. Tai than the concentrations observed at other monitoring...
The research reveals the distribution and correlation of heavy metals in groundwater of sewage irrigation area in Guangdong province. 14 groundwater samples were collected in August 2008, and the groundwater samples were filtrated through 0.45 μm membranes and acidified in the field. Determinations of Cd, Cu, Zn, Pb, Ni, and Cr in all the samples were performed using ICP-OES, and determinations of...
To examine the effective leadership behavior for improving employee engagement (task focus, vigor, initiative participation, internalized value, efficacy, and positive persistence) in China hotel industry, the total of 354 samples are collected from full-time employees in 5 service hotels in China by Multiple Employee Engagement Inventory (MEEI) and Multifactor Leadership Questionnaire (MLQ). Results...
Combining theories and using real data, this paper empirically analysis the dynamic relationship, transmission mechanisms, information impact between RMB NDF (Non-deliverable Forwards) exchange rate and domestic DF (deliverable forward foreign exchange) rate. The purpose of this study is not intending to propose pricing mode, but finding the relationship under diversity of investors and capital bound...
Based on social exchange theory and the principle of reciprocity, this paper discusses the relationships among employees' perceived organizational support (POS), job satisfaction, turnover intention and locus of control, and proposes a theoretical model that job satisfaction mediates the relationship between perceived organizations and turnover intention, and 384 employees were assessed as a sample...
Total of 120 soil samples from the topsoil (0-20 cm) at an approximate interval of 100 m were collected in Wutan, China, to determine the spatial variability of five heavy metals, Cd, As, Hg, Pb, and Cr, with classical statistical and geostatistical analyses. Ordinary kriging was utilized for estimating heavy metals determination. Classical statistical indicated that As, Pb, and Cr concentrations...
Research and development teams ( R&D teams) is commonly used in organizations today to solve problems and accomplish creative tasks. But there is little known about the variables that affect team-level creativity, and the optimal conditions that promote it, and how to design team for optimal creative and high quality performance. Because the idea of creative synergy has much to offer in terms...
