[Effects of Different Amendments on Fractions and Uptake by Winter Wheat in Slightly Alkaline Soil Contaminated by Cadmium and Nickel].

The effects of a single application of three amendments (biochar, lignite, and chicken manure) on the fraction transformations of soil Cd and Ni and uptake by winter wheat are reported to provide reference for passivation and the remediation of heavy metals in soil. Field experiments were conducted to investigate the effects of different passivators on the forms of Cd and Ni in soils at different growth stages of winter wheat, and to analyze the contents of Cd and Ni in different organs of wheat. The results showed that biochar increased soil pH and that lignite reduced soil pH, but not significantly.

Photoelectrocatalytic degradation of atrazine by boron-fluorine co-doped TiO nanotube arrays.

Atrazine, one of the most widespread herbicides in the world, is considered as an environmental estrogen and has potential carcinogenicity. In this study, atrazine was degraded on boron-fluorine co-doped TiO nanotube arrays (B, F-TiO NTAs), which had similar morphology with the pristine TiO NTAs. The structure and morphology of TiO nanotube samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV-visible diffuse reflectance spectroscopy (DRS).

[Potential Ecological Suitability Regionalization Analysis of Angelica sinensis Based on GIS and Fuzzy Matter Element Model].

Objective: To study the potential ecological suitability regionalization of Angelica sinensis, for protecting wild resources and selecting cultivation location and designing rational production layout.

Methods: Based on fuzzy matter element model, the relationship of fuzzy membership function between ferulic acid content and 14 ecological factors, including climate, topography and soil,were established. Then information entropy theory was used to determine the relative importance of each environmental factor, and thus to determine the most limiting habitat criteria.

[Expression of stathmin in esophageal squamous cell carcinoma and its biological significance].

Objective: To explore the expression of stathmin gene in esophageal squamous cell carcinoma (ESCC) and its correlation to oncogenesis of ESCC.

Methods: Three ESCC cell lines, 75 ESCC samples, 25 tumor-adjacent samples and 30 normal esophageal mucosa samples were examined for the expression of stathmin mRNA and protein by in situ hybridization and immunohistochemistry, respectively. The correlations of stathmin expression to the clinicopathological features of the patients were analyzed.

[Mechanism of the organic pollutant degradation in water by hybrid gas-liquid electrical discharge].

The method of hybrid gas-liquid electrical discharge was investigated for the removal of phenol. The results indicate that this new method can remove phenol in water effectively. The removal rate increases with increasing voltage and air aeration.

Removal of phenol by activated alumina bed in pulsed high-voltage electric field.

A new process for removing the pollutants in aqueous solution-activated alumina bed in pulsed high-voltage electric field was investigated for the removal of phenol under different conditions. The experimental results indicated the increase in removal rate with increasing applied voltage, increasing pH value of the solution, aeration, and adding Fe2+. The removal rate of phenol could reach 72.
