During the construction of coastal projects, the formation of seepage channels within the soil body, induced by fluctuating water pressure, can result in consequential damage to the soil structure, ultimately culminating in sudden water gushing sand disasters. In order to investigate the impact of static and dynamic seepage pressures on sand flow and water flow conditions, an intelligent water pressure loading device was devised to consistently apply a confining pressure of 60 kPa to the specimens. The three static seepage pressures and nine fluctuating seepage pressures were applied to the specimens under the condition of constant confining pressure to study the effect of static and dynamic seepage pressures on sand flow and flow conditions. The outcomes of the experiments revealed that, when the base water pressure of the dynamic seepage pressure is the same as the static seepage pressure, the cumulative seepage volume and permeation velocity of the dynamic seepage pressure are always larger than that of the static seepage pressure. Moreover, higher static pressures increase forces on particles, enhancing permeation velocity, and cumulative seepage volume. Notably, longer periods of pressure fluctuations in dynamic seepage pressures and lower basic water pressures weaken the effect of dynamic seepage pressures. [ABSTRACT FROM AUTHOR]

Nella Larsen's Quicksand (1928) demonstrates a situated form of Black cosmofeminism to capture the difficult process through which a deviant mixed-race heroine negotiates her place in the Black community. At core, Black cosmofeminism interrogates oppressive racial and sexual politics enacted in domestic, local, and national spheres to envision a more inclusive cosmopolitan US Black community open to sexually, racially, and nationally "impure" subjects. However, far from advocating the erasure of local identities, such a reimagining of the domestic Black community as cosmofeminist instead foregrounds group identification and communal bonding developed in response to transnational displacement and discrimination. Working in tandem with consumer cosmopolitanism, Black cosmofeminism places the African American woman consumer center stage and traces how her desire, body, and identity are not only constructed alongside globally circulated commodities but also made localized and resistant to the global commodification and sexualization of Black and mixed-raced women.

In the article, the feature of settlement, subsidence, and other deformations in the ground foundations of various structures built in complex engineering-geological conditions with the joint participation of some soils with a stable structure (subsidence loess, silt, low-strength technogenic, soluble) are performed on the example of the Gazakh cement plant, the development of a conceptual solution for the methods of installation in foundations on such soils has been reflected. Analyzing the results of the complex engineer-geological research conducted at the research facility, priority was given to the principle of improving the working conditions of the soils that form the basis of the facilities in order to prevent the predicted large-scale deformation, the application of a foundation system consisting of piles with a large length, with the bottom placed in a layer of argillite-like very stiff clay, was accepted as the most correct technical solution, the dimensions of the pile are determined and installed in the study area and it was determined that the chosen solution was justified by monitoring the deformations.
