Contextual modulation of the red-attractiveness effect: Differences in affiliation and competitive settings.

Color is not just about aesthetics but also communicates specific information and has important implications for psychological functioning. It has been shown that the color red enhances perceived attractiveness when evaluating the opposite sex, which we call the red-attractiveness effect. However, few studies have attached importance to the social context in which attractiveness ratings are made, which means that the red-attractiveness effect is rarely explained by analyzing the role of social context.

Humic acid coupled with coal gasification slag for enhancing the remediation of Cd-contaminated soil under alternated light/dark cycle.

In this study, the synthesis of a coal gasification slag-humic acid (SA) hybrid was purposed for the remediation of cadmium (Cd)-contaminated soil. In order to investigate the effect of SA on the Cd-contaminated soil and plant growth, a series of experiments were carried out under different illumination condition. The results showed that the SA has some the photocatalytic activity, and adding 10 wt% of SA to the soil could obviously improve the soil fertility and decrease the mobility of Cd in the soil under alternated light/dark cycle (12L/12D); the content of the residual fraction in the SA-amended soil reached 69.

Effects of humic acid-modified magnetic FeO/MgAl-layered double hydroxide on the plant growth, soil enzyme activity, and metal availability.

The synthesis of a humic acid-layered double hydroxide (HA-LDH) hybrid was purposed for the remediation of contaminated soils in mining area. The hybrid was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscope and energy dispersive spectrometer. In order to investigate the effect of HA-LDH on the mine soil, greenhouse experiments of Artemisia ordosica were carried out under different concentrations of amendments (0, 1%, 3%, 5%, 7%).

Effects of sewage sludge modified by coal gasification slag and electron beam irradiation on the growth of Alhagi sparsifolia Shap. and transfer of heavy metals.

A greenhouse experiment was performed to investigate the feasibility of sewage sludge modified by coal gasification slag pretreatment and electron beam irradiation in soil application for cultivation of Alhagi sparsifolia Shap . The results showed that modified sewage sludge had an active effect on the growth of Alhagi sparsifolia Shap . The sandy soil and modified sludge at the volume ratio of 2:1 were optimal, and the growth potential of Alhagi sparsifolia Shap .

Cobalt-60 gamma-ray irradiation pretreatment and sludge protein for enhancing enzymatic saccharification of hybrid poplar sawdust.

In order to improve the enzymatic saccharification of hybrid poplar sawdust, gamma irradiation pretreatment and enzymatic hydrolysis in the presence of sludge protein were investigated. The cellulose crystallinity index were significantly decreased after irradiation pretreatment, and adding sludge protein improved enzyme activity and increased the reducing sugar yield. The conditions of irradiation pretreatment and enzymatic hydrolysis in the presence of sludge protein were systematically examined.
