Poloxamers are also known by the trade names Pluronic, [2] Kolliphor (pharma grade), [3] and Synperonic. [ 4 ] Because the lengths of the polymer blocks can be customized, many different poloxamers exist that have slightly different properties.
Open channel applications include bank stabilization, flow and grade control, scour protection for bridge piers, and biostabilization. The primary mechanism of protection employed is an increase in the relative roughness of the channel bank (as characterized by the Manning's Roughness Coefficient ); the Manning's n is relatively high at 0.1.
Palette stacked autoclaved aerated concrete blocks. Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. It is most suitable for producing concrete-like blocks [1] and as an eco-friendly alternative to such.
The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement.

A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
Accropode concrete armour units are applied in a single layer. Ecopode (1996) The Ecopode armour unit with a rock-like appearance was developed by Sogreah to enhance the natural appearance of concrete armourings above low water level. A patent application was filed in 1996.
Materials (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions (e.g., acetone, ethanol). Liquids having a flash point below 22.8 °C (73 °F) and having a boiling point at or above 37.8 °C (100 °F) or having a flash point between 22.8 and 37.8 °C (73 and 100 °F).
TCX Technology is the brand name for a hydrocarbon-based ethanol production process developed and marketed by Celanese Corporation.Celanese researchers developed the TCX Technology in its Clear Lake City, Texas plant under the direction of its CEO to create a fuel that helps countries reduce their need to import oil and gas.
