Abstract: Retracted paper: Evaporation of a saline solution from a porous medium often leads to the formation of salt efflorescence at the surface of the medium. We look at the special case where the medium is formed by the assembly of fine and coarse medium vertical columns perpendicular to the evaporation surface and where there is a continuous wicking of the solution into the medium in combination with evaporation. Experiments lead to distinguish two main cases depending on the development or not of the efflorescence at the surface of the coarse medium. On the contrary, the presented analysis suggests that the coarse medium surface colonization occurs when the evaporation flux is sufficiently high no matter what the type of efflorescence is on the fine medium surface. In addition, the analysis suggests that the colonization will always occur when the supersaturation is close to the solubility.

Abstract: De-colonization is an integrated part of modernization of the process of the 20th century in the world. It can be understood as a process which embodies two parallel movements-the colonized people’s struggle for independence and the colonial metropolitan country’s reaction. This paper takes the Zhongshan Park (formal Quanye Expo) in Tianjin’s Chinese settlements as a specific case and investigates the interplay between native culture and colonial culture in the park building process. Through investigating the Chinese Municipal Parks, the paper elucidates the conflicts between colonialism and nationalism contextualized in Sino-West cultural encounters, and reveals the Chinese efforts for cultural de-colonization in early 20th century.

Abstract: Extrusion is a perspective forming technology for obtaining objects with certain profile, important for the TiO2 application as biomaterial. Extruded samples were calcinated at 1100 °C, thermally treated in different atmospheres: at 1450 °C in air and at 1300 °C in vacuum. An approach was made to examine the adhesion and colonization intensity of Staphylococcus epidermidis and Pseudomonas aeruginosa on TiO2 ceramic in vitro. It was found that Ps.aeruginosa demonstrated higher adhesion and colonization intensity as S.epidermidis and TiO2 samples treated in vacuum demonstrated higher attachment of microorganisms as TiO2 samples treated in air. It was supposed that surface charge promoted the bacterial adhesion on the vacuum treated samples.
