    Description: We investigate the effects of shoreline change and protective structures (seawalls) on home values, using data on residences sold between 2000 and 2010 in the coastal towns of Marshfield, Duxbury, and Plymouth, Massachusetts. These towns comprise shorelines that exhibit moderate rates of shoreline change, relative to other shorelines in the state, with extensive armoring. We investigate explicitly the effects of hard structural protection in combination with environmental amenities and hazards (distance to a beach, elevation of a property, location in a flood zone). We find that homeowners pay a premium in housing markets for nearshore properties protected by nature (higher elevations or more stable shorelines) or by humans (seawalls). The average marginal increase in nearshore property values associated with a 1m rise in elevation is 2 percent, a 1m (horizontal distance) decrease in the erosion rate is 0.2 percent, and location behind a seawall is 10 percent. The effects of erosion, elevation, and seawalls appear to be limited to properties located in close proximity to water or to oceanfront residences. Overall, the benefits of access to ocean amenities dominate the risks of exposures to hazards associated with shoreline change.

    A Bayesian Network Method for Quantitative Evaluation of Defects in Multilayered Structures from Eddy Current NDT Signals (2014)

    Publication Date: 2014-03-26
    Description: Accurate evaluation and characterization of defects in multilayered structures from eddy current nondestructive testing (NDT) signals are a difficult inverse problem. There is scope for improving the current methods used for solving the inverse problem by incorporating information of uncertainty in the inspection process. Here, we propose to evaluate defects quantitatively from eddy current NDT signals using Bayesian networks (BNs). BNs are a useful method in handling uncertainty in the inspection process, eventually leading to the more accurate results. The domain knowledge and the experimental data are used to generate the BN models. The models are applied to predict the signals corresponding to different defect characteristic parameters or to estimate defect characteristic parameters from eddy current signals in real time. Finally, the estimation results are analyzed. Compared to the least squares regression method, BNs are more robust with higher accuracy and have the advantage of being a bidirectional inferential mechanism. This approach allows results to be obtained in the form of full marginal conditional probability distributions, providing more information on the defect. The feasibility of BNs presented and discussed in this paper has been validated.

    IJERPH, Vol. 13, Pages 1107: Mercury Exposure in Children of the Wanshan Mercury Mining Area, Guizhou, China (2016)
    MDPI Publishing
    Details
    Publication Date: 2016-11-09
    Description: To evaluate the mercury (Hg) exposure level of children located in a Hg mining area, total Hg concentrations and speciation were determined in hair and urine samples of children in the Wanshan Hg mining area, Guizhou Province, China. Rice samples consumed by these same children were also collected for total mercury (THg) and methyl-mercury (MeHg) analysis. The geometric mean concentrations of THg and MeHg in the hair samples were 1.4 (range 0.50–6.0) μg/g and 1.1 (range 0.35–4.2) μg/g, respectively, while the geometric mean concentration of urine Hg (UHg) was 1.4 (range 0.09–26) μg/g Creatinine (Cr). The average of the probable daily intake (PDI) of MeHg via rice consumption was 0.052 (0.0033–0.39) µg/kg/day, which significantly correlated with the hair MeHg concentrations (r = 0.55, p 〈 0.01), indicating that ingestion of rice is the main pathway of MeHg exposure for children in this area. Furthermore, 18% (26/141) of the PDIs of MeHg exceeded the USEPA Reference Dose (RfD) of 0.10 µg/kg/day, indicating that children in this area are at a high MeHg exposure level. This paper for the first time evaluates the co-exposure levels of IHg and MeHg of children living in Wanshan mining area, and revealed the difference in exposure patterns between children and adults in this area.

    Description: Minerals, Vol. 7, Pages 195: The Influence of Backwater Al3+ on Diaspore Bauxite Flotation Minerals doi: 10.3390/min7100195 Authors: Chaojun Fang Ziyong Chang Qiming Feng Wei Xiao Shichao Yu Guanzhou Qiu Jun Wang The effect of Al3+ in backwater on the flotation of diaspore bauxite was investigated by micro-flotation tests and the underlying mechanisms were investigated by inductively coupled plasma (ICP) measurement, zeta potential measurements, solution chemistry analyses, and synchrotron near edge X-ray absorption fine structure (NEXAFS) analyses. The ICP measurement results show the concentration of Al3+ in backwater was up to 1 × 10−4 mol/L. The micro-flotation results indicated that backwater Al3+ reduced the flotation recovery of diaspore and improved the flotation recovery of kaolinite at pH 9, which was the pH value used in the industrial flotation. The adsorption of Al3+ species changed the zeta potential, the Al atomic abundance, and the number of active sites on the mineral surface. In particular, the result of solution chemistry analyses and synchrotron NEXAFS analyses show that the Al3+ in backwater was adsorbed on the mineral surface in the form of Al(OH)3 (s), and the bond of –Al–O–Al–(OH)2 or –Al/Si–O–Al–(OH)2 was formed at pH 9. It changed the intensity of hydrogen bond force between minerals and collectors, and resulted in the depression of diaspore flotation and the activation of kaolinite flotation. This study can be used to guide the application of backwater in the flotation of diaspore bauxite in industry.

    Minerals, Vol. 7, Pages 113: The Activation Mechanism of Bi3+ Ions to Rutile Flotation in a Strong Acidic Environment (2017)
    MDPI Publishing
    In: Minerals
    Details
    Publication Date: 2017-07-03
    Description: Lead hydroxyl compounds are known as rutile flotation of the traditional activated component, but the optimum pH range for flotation is 2–3 using styryl phosphoric acid (SPA) as collector, without lead hydroxyl compounds in slurry solution. In this study, Bi3+ ions as a novel activator was investigated. The results revealed that the presence of Bi3+ ions increased the surface potential, due to the specific adsorption of hydroxyl compounds, which greatly increases the adsorption capacity of SPA on the rutile surface. Bi3+ ions increased the activation sites through the form of hydroxyl species adsorbing on the rutile surface and occupying the steric position of the original Ca2+ ions. The proton substitution reaction occurred between the hydroxyl species of Bi3+ ions (Bi(OH)n+(3−n)) and the hydroxylated rutile surface, producing the compounds of Ti-O-Bi2+. The micro-flotation tests results suggested that Bi3+ ions could improve the flotation recovery of rutile from 61% to 90%, and from 61% to 64% for Pb2+ ions.

    Genetic variant in SWI/SNF complexes influences hepatocellular carcinoma risk: a new clue for the contribution of chromatin remodeling in carcinogenesis (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-22
    Description: Chromatin remodeling has been newly established as an important cancer genome characterization and recent exome and whole-genome sequencing studies of hepatocellular carcinoma (HCC) showed that recurrent inactivating mutations in SWI/SNF subunits involved in the molecular basis of hepatocarcinogenesis. To test the hypothesis that genetic variants in the key subunits of SWI/SNF complexes may contribute to HCC susceptibility, we systematically assessed associations of genetic variants in SWI/SNF complexes with HCC risk using a two-staged case-control study in Chinese population. A set of 24 single nucleotide polymorphisms (SNPs) in SWI/SNF complexes were examined in stage 1 with 502 HCC patients and 487 controls and three promising SNPs (SMARCA4 rs11879293, rs2072382 and SMARCB1 rs2267032) were further genotyped in stage 2 comprising 501 cases and 545 controls for validation. SMARCA4 rs11879293 presented consistently significant associations with the risk of HCC at both stages, with an OR of 0.73 (95% CI: 0.62–0.87) using additive model in combined analysis. Moreover, the decreased risk of HCC associated with SMARCA4 rs11879293 AG/AA was more evident among HBsAg positive individuals (OR = 0.47, 95% CI: 0.27–0.80) in combined analysis. The study highlighted the potential role of the SWI/SNF complexes in conferring susceptibility to HCC, especially modified HCC risk by HBV infection. Scientific Reports 4 doi: 10.1038/srep04147
