We have determined that the organic matrix of calcium oxalate kidney stones contains a glycoprotein inhibitor of calcium oxalate crystal growth (nephrocalcin) that resembles nephrocalcin present in the urine of patients with calcium oxalate stones and differs from nephrocalcin from the urine of normal people. Pulverized calcium oxalate renal stones were extracted with 0.05M EDTA, pH 8.0; nephro...

When embankment is constructed on very soft soil, special construction methods are adopted. One of the techniques a piled embankment. Piled (stone columns) embankments provide an economic and effective solution to problem constructing over soils. This method can reduce settlements, time cost. Stone columns improvement for soils under light structures such as rail or road embankments. The presen...

Owing to the shortcomings of blindness and inaccuracy when backfilling in goafs based on key stratum theory, we propose “multi-arch pier-column” method. This method involves drilling holes at specific locations surface inject filling slurry materials into goaf separation area under stratum. allows broken gangue be cemented form a stone body, improve its overall strength. process, along with str...

This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The  unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...
