In soft soil foundations, geogrid encased stone column composite foundation technology has been widely applied and developed in recent years due to its efficient treatment. this study, eight groups of laboratory model tests were performed a large-scale testing tank investigate the bearing mechanism stress characteristics columns under traffic loads with different cyclic load ratios. The at bott...

To explore the clinical effect of percutaneous transhepatic cholangioscopic lithotomy (PTCSL) combined with rigid choledochoscope and accurate positioning in the treatment of calculus of bile duct. This study retrospectively reviewed 162 patients with hepatolithiasis at the First Affiliated Hospital of Guangzhou Medical University between 2001 and 2013 were assigned to hard lens group or tradit...

Rhinolith is a stone like nasal mass uncommon in children and adolescent. Diagnosis of rhinolithiasis may be difficult because of the possibility of varying clinical presentations. We report 2 cases in adults. The first was 23 years old female having unilateral nasal obstruction, cacosmia and occasional blood stained nasal discharge. The second case was that of a 47 years old male having unilat...

Falling of rigid body through air, water, and sediment with high speed is investigated experimentally and theoretically. Several experiments were conducted to shoot bomb-like rigid bodies with the density ratio similar to MK84 into the hydrographical tank. During the experiments, we carefully observe the position and orientation of the bomb-like rigid bodies. The theoretical work includes the d...
