Bird dropping in terminology of stone deterioration pattern is a sub branch of deposit decay, means accumulation of exogenic materials, on stone surface, dropping has a main role in deterioration of buildings and stone monuments. Birds not only to build the nests and noisy cause to bother, but also due to transfer of variety disease into human, especially when it drops any place and then this d...

A large-scale immersion experiment was carried out to assess the collapsibility characteristics of loess in Bu Li village located Weibei Loess Tableland, and seepage evolution were determined. The effects void ratio, natural moisture content, material composition, microstructure on characterized by X-ray diffraction, scanning electron microscopy, water-soluble salt analysis elucidate mechanisms...

Bile salts are surfactants that partition into phospholipid bilayers. When liposomes or membranes are exposed to mixed solutions of bile salts, the more hydrophobic bile salt species associate preferentially with the lipid bilayer. As a consequence, in the aqueous phase, the free monomeric concentration of bile salt declines and the more hydrophilic species become relatively enriched. Above a c...

Rice straw gasification was carried out in a laboratory fluidized bed reactor system from 600 to 800 ◦C in order to well-understand the release and occurrence mode of alkali metals as a function of temperature during the gasification process. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was applied to analyze the original rice straw and obtained fly ash at different tempera...
