In the scope of the paper studying the pile group effect in case of multilayered foundation, especially the effect of porous, medium-tight sand layers in the foundation on the load bearing capacity and subsidence of friction piles, the following issues are clarified: (i) coefficient of pile group in multi-layered foundation, with sand and clayey soil layer; (ii) distribution of forces along the pile shaft; (iii) effect of pile group on settlement of the pile group.

We have studied the spatiotemporal evolution of surface deformation in Konya city and its vicinity using advanced multitemporal synthetic aperture radar techniques with SAR data acquired by Envisat, ALOS-1, and Sentinel-1 A/B satellites between 2004 and 2020. Velocity maps and time series show that the city has been subsiding with varying rates in space and time since 2004. The pattern of deformation shows two main lobes of subsidence centered in the western and eastern sides of the city with a nondeforming north-south trending narrow zone in between.

"Hố tử thần" thực chất là hiện tượng sụt sập nền đất (ground collapse) hay sụt lún nền đất (ground subsidence), một quá trình địa chất vẫn thường xảy ra trong tự nhiên nhưng thời gian gần đây nó lại chủ yếu liên quan đến hoạt động của con người như các dự án cải tạo, lắp đặt hệ thống đường ống cấp thoát nước. Vậy có thể khắc phục tình trạng này bằng những giải pháp nào? ...

Polymorphous Light Eruption After sunburn, the most common type of photosensitivity disease is polymorphous light eruption (PLE), the mechanism of which is unknown. Many affected individuals never seek medical attention because the condition is often transient, becoming manifest each spring with initial sun exposure but then subsiding spontaneously with continuing exposure, a phenomenon known as "hardening.

The challenges have refused to subside. Instead they continue to stimulate urgent need for a new debt sustainability framework and debt management orientation that can allow for the borrowing economies to break the vicious circle of unending distress.
