Two cores were selected in the Changjiang Estuary and its adjacency,one within the region of seasonal hypoxia and the other nearby but outside the hypoxia *** major elements,trace elements and rare earth elements(REEs)were determined on the 210Pb-dated sediment *** distributions of most elements in the core sediment outside the hypoxia region were controlled by “grain size effects”.In the core sediment within the hypoxia region,some redox sensitive elements(RSEs)just like the Mo,Cd,As et *** been enriched significantly,which concentrations increased about 83%,73%and 50%respectively since the late 1960s to *** the Mn has been depleted since *** results indicate the redox environment of the bottom water-sediment interface has been changed which might be caused by the eutrophication and hypoxia in the Changjiang *** concentrations of biogenic elements as well as Ca,Sr,P have also increased about 129%,65%and 38%respectively since the late 1960s,which reflected the increasing of productivity and biomass influenced by the anthropogenic activities during the last forty *** results showed that the contents of biogenic elements as well as Ca,Sr,P and some RSEs just like Mo,Cd,As,Mn in sediment could be used to trace or reconstruct history of the coastal eutrophication and hypoxia in the high productivity zone in the Changjiang Estuary over the last 100 *** were correlated negatively with Ti,Al,Fe and no obvious relation with grain *** decreasing trend of δCe distribution over the last 100 years may be related to the progressive hypoxia and high productivity in the Changjiang *** geochemical parameters gave the same conclusions consistently: effected by the anthropogenic activity,the Changjiang estuary hypoxia began in 1970s and showed the increasing trend.

Objectives Subclinical thyroid disorders are common in pregnant women, which are associated with adverse pregnancy outcomes. Physiological changes in pregnancy and the lack of pregnancy-specific reference ranges pose great challenge for the managements of subclinical thyroid disorders in pregnancy. We aimed to establish trimester-specific thyroid hormone reference intervals throughout pregnancy in southern Chinese population. Methods we measured the serum thyroid hormone (TSH, FT4, TPO-AB) using Abbott electrochemiluminescence immunoassay in 5589 pregnant women during 2012–2013. Patients with known thyroid disorders, autoimmune disease, recurrent miscarriage, hyperemesis gravidarum and pre-eclampsia were excluded. Trimester-specific reference ranges (2.5th, 97.5th centiles) were calculated. Results TSH median T1: 1.19 ± 0.99 mIU/L ( N = 3532), T2: 1.40 ± 1.02 mIU/L ( N = 1623), T3: 1.48 ± 1.30 mIU/L ( N = 434). FT4 median T1: 15.7 ± 3.12 pmol/L ( N = 3532), T2: 13.81 ± 2.99 pmol/L ( N = 1623), T3: 12.92 ± 2.98 pmol/L ( N = 434). TSH reference range T1: 0.01–3.55 mIU/L, T2: 0.01–4.13 mIU/L, T3: 0–4.67 mIU/L. FT4 reference range T1: 12–21.44pmol/L, T2: 10.01–19.36 pmol/L, T3: 9.29–20.31 pmol/L. TSH slightly increased throughout gestation. FT4 decreased throughout gestation. Conclusions We established pregnancy-specific thyroid function reference intervals of southern Chinese population, which is beneficial in clinical practice. Disclosures L. Liu: None. X. zhang: None.

In this paper, we investigate bounded traveling waves of the generalized nonlinear Klein-Gordon model equations by using bifurcation theory of planar dynamical systems to study the effects of horizontal singular straight lines in nonlinear wave equations. Besides the well-known smooth traveling wave solutions and the non-smooth ones, four kinds of new bounded singular traveling wave solution are found for the first time. These singular traveling wave solutions are characterized by discontinuous second-order derivatives at some points, even though their first-order derivatives are continuous. Obviously, they are different from the singular traveling wave solutions such as compactons, cuspons, peakons. Their implicit expressions are also studied in this paper. These new interesting singular solutions, which are firstly founded, enrich the results on the traveling wave solutions of nonlinear equations. It is worth mentioning that the nonlinear equations with horizontal singular straight lines may have abundant and interesting new kinds of traveling wave solution.

In real systems, generous individuals who prefer to contribute can play more important roles on the public than selfish individuals. Inspired by this, a spatial public goods game with weighted and conditional strategies is proposed in this paper. In our model, a player's contribution behavior is mainly determined by the less cautious neighbors rather than those more cautious ones. The weight effect is adjusted by a non-negative parameter a. Our results show that the number of strategies increases with the weight parameter a for the low multiplication factor r. On the contrary, for the high multiplication factor r, the less cautious cooperators are more likely to appear in the system. (C) 2013 Elsevier B.V. All rights reserved.

Novel graphite sheet (GTS) has been used as anodic catalyst in microbial fuel cell (MFC) base on Escherichia coli (ATCC 25922) and characterized by cyclic voltammogram (CV) and polarization curve. Findings from these measurements revealed that GTS showed an excellent electrochemical performance. The two-chambered MFC operated with the GTS anode delivered a maximum power density of 2249 mW/m(2). Scanning electron microscopy (SEM) results indicate that the high power output could be attributed to the high biocompatibility of the GTS. These results demonstrate that the GTS is promising in the application of microbial fuel cells. (C) 2013 Elsevier B.V. All rights reserved.
