) A form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colorless and transparent, but sometimes also yellow, brown, purple, green, and of other colors; also in cryptocrystalline massive forms varying in color and degree of transparency, being ...
Rocksconsist of minerals. A mineral is a material that occurs naturally and is generally strong, crystalline, stable and inorganic at room temperature. There are many known mineral species, but the vast majority of rocks are formed by combinations of a few common minerals, called “rock-forming...
Its oxides form a family of anions known as silicates. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, ...
Common Mistakes in Concrete Coring in Auckland Inadequate Site Assessment: One of the most frequent errors is failing to properly assess the site before coring. This can lead to drilling into embedded utilities like gas lines or water pipes. Proper site evaluation can provide crucial information abo...
Spur and gully morphology that is common in canyon walls of this region is visible along the upper portions of the depression walls, whereas the lower portions of the walls are covered with talus debris. Part of the depression floor is also covered by debris, which exhibit mounds and blocks ...
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the...

) A member of a common form of truss, as a roof truss. It is strictly a tie, intended to prevent the sagging of the tiebeam in the middle. If there are struts, supporting the main rafters, they often bear upon the foot of the king-post. Called also crown-post. King's Bench ()...
the concept of numerical aperture becomes similar to those of multimode fibers. The numerical aperture of multimode fibers is usually larger than those of single-mode fibers. The most common lasers appropriate for applications over single-mode fiber include distributed feedback (DFB) and Fabry–Pero...
