Excavation near or above existing shield tunnels often results in adverse impacts on tunnel stability.To ensure the serviceability of existing tunnels, this paper presents experimental and numerical studies with reference to a foundation pit case history excavated above twin-tube shield tunnels in soft soils.The experimental tests were firstly appl

We analyse how particles adhering to a wall can create tree-like structures (or flat trees) by an erosive flow.We vary the physical and chemical properties of the fluid and highlight their influences on Fridge Baffle Motor the patterns observed.We analyse the structures created and conclude that the mass concentration in particles have a clear impa
Primary squamous cell carcinoma of the renal parenchyma is a rare entity and only 4 cases have been reported in the literature.A 73-year-old female patient presented to our Laser and party lighting clinic with the complaint of right flank pain.On radiologic evaluation, a 6x5x4 cm hypodense mass showing heterogeneous contrast enhancement was observe
In this in vitro study, the influence of the concentration of abrasive particles on the abrasivity of toothpastes was investigated using laser scan profilometry on polymethyl methacrylate (PMMA) surfaces with the aim of providing an alternative method to developers for screening of new toothpaste formulations.PMMA plates were tested in a toothbrush
