Acid Erosion
There is a dental epidemic occurring literally right under our noses in this country that is largely unrecognized or mis-diagnosed. It is unparalleled in the history of man because of a combination of present day factors that have never existed before, and it is causing widespread damage to the dental health of millions of Americans. Furthermore, it is relatively simple to recognize and there a...
متن کاملHydraulic erosion
This paper presents a generalized solution to modelling hydraulic erosion using ideas from fluid mechanics. The model is based on the Navier–Stokes equations, which provide the dynamics of velocity and pressure. These equations form the basis for the model to balance erosion and deposition that determine changes in the layers between water and erosion material. The eroded material is captured a...

متن کاملTooth Erosion
Epidemiology Few epidemiological studies of the prevalence and severity of tooth erosion have yet been performed on a national basis. Studies have focused on small groups of patients, often pre-selected, for example because of symptoms. Thus erosion was seen largely in patients with symptoms of gastric reflux (Gastro-oesophageal reflux disease or GORD) and later was recognised in patients with ...
متن کاملComparison of cavitation erosion rate with liquid impingement erosion rate
Both cavitation erosion and liquid impingement erosion are phenomena that can cause pipe wall thinning in power plants. The Code for Power Generation Facilities, Rules on Pipe Wall Thinning Management, was published by the JSME (Japan Society of Mechanical Engineers) in 2005. The code says that cavitation erosion shall be prevented either in the design stage or by daily inspection. On the other...
