Harlequin Ichthyosis Causes. The harlequin ichthyosis is known to be genetic in nature. The ABC 12 gene, which directs the protein production that is necessary to have a normal skin growth, is being mutated which leads to this severe skin disorder. It is a gene that is responsible for the transportation of lipid.
Boron (IPA: /ËbÉËrÉn/) is a chemical element with atomic number 5 and the chemical symbol B. A trivalent compound containing boron occurs abundantly in the ore borax. Boron is never found free in nature, and is a non-metal. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs' scale), and a weak conductor at room temperature.
Boron compounds, such as borax and boric acid, have many uses. Boron-10 is used as a control for nuclear reactors, to detect neutrons, and as a shield for nuclear radiation. Sources: Boron is not found free in nature, although boron compounds have been known for thousands of years.he boron mineral ulexite exhibits natural fiberoptic properties. Elemental boron transmits portions of infrared light. At room temperature, it is a poor electrical conductor, but it is a good conductor at high temperatures.
