one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

Tidal basins are described by major features such as tidal flat, tidal channel, intertidal area, and tidal prism, which have been formulated by some empirical relations based on field observations. Although empirical relations explain some morphological patterns, those are not applicable to all conditions. Due to the lack of observations for different areas and under different geophysical condi...

An oil spill model coupled with a hydrodynamic model was developed to simulate the spread of oil slick in real marine conditions considering the effects of tidal currents, wind and wave. The hydrodynamic model is verified using the measurements of tidal elevations and current speeds at the Persian Gulf. Effect of various governing factors on oil slick movement, tidal currents, wind and wave, ar...

Tidal Stream Energy Extraction in Coastal Basins A thesis submitted for the degree of Doctor of Philosophy Scott Draper St Catherine's College, Oxford Trinity Term 2011 In recent years the extraction of energy from tidal streams has grown in popularity as a potential source of clean renewable energy. To extract this energy, tidal devices, resembling underwater turbines or hydroplanes, are deplo...

Tidal energy is a clean,  reliable and available  energy that  exits vastly. Moreover, it can be offered to most of coastal  regions and cities. This clean energy  can be used in littoral  zones worldwide , together with islands and coasts ofIransuch as Chabahar. Furthermore, from ecosystem point of view, this energy is useful for increasing coral reefs and also using organic materials in diffe...

A tidal bore may occur in a macro-tidal estuary when the tidal range exceeds 4.5–6 m and the estuary bathymetry amplifies the tidal wave. Its upstream propagation induces a strong mixing of the estuarine waters. The propagation of undular tidal bores was investigated herein to study the effect of bridge piers on the bore propagation and characteristics. Both the tidal bore profile and the turbu...

in recent years, several ocean tide models have been used to calculate tides using data of satellite and tide gauges data. global ocean tide models have many applications in various sciences such as geophysics, geology and geodesy and oceanography. considering­ the existence of many models, a quantitative evaluation of research, and ranking and selecting the best model of the global ocean tide ...

MilkyWay@home is a volunteer computing project that allows people from every country in the world to volunteer their otherwise idle processors to Milky Way research. Currently, more than 25,000 people (150,000 since November 9, 2007) contribute about half a PetaFLOPS of computing power to our project. We currently run two types of applications: one application fits the spatial density profile o...
