Experimental Study on Influence of Lime on Cross-Scale Characteristics of Cemented Backfill with Multiple Solid Wastes.

The utilization of industrial solid waste in mines is an important approach to resource utilization. The backfill material in mines is mainly composed of solid waste, which plays a supporting role. The excitation effect of lime on phosphogypsum and fly ash in backfill was studied in this paper.

Experimental Study of Salicylic Acid as a Calcium Sulfate Dihydrate Scale Inhibitor, Analyzed from Surface Properties and Crystal Growth.

Static and dynamic experiments were carried out to study the antiscale performance of salicylic acid (SA) to calcium sulfate dihydrate (CSD) scale. The CSD scale formed in the reuse of processing of wastewater of phosphorite flotation. The scale surface physicochemical properties have been investigated by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ζ potential, and contact angle measurements.

[Insect diversity of different habitat types in Zhalong Wetland, northeast China].

In order to approach the effects of different habitat types in wetland on insect diversity, an investigation was conducted on the insects in eight types of habitats in Zhalong Wetland. A total of 5822 insects were collected, belonging to 143 species, 58 families, and 11 orders, among which, Orthoptera, Dipteral and Odonata were the dominant taxa. The species diversity was the highest in grassland meadow, and the Shannon diversity index and evenness index were higher in lakeside but the lowest in wet meadow.
