The linguistic root of tzaraath may mean smiting, in comparison with Arabic, in reference to a Talmudical explanation that it serves as a punishment for sin; it is quite possible that tzaraath was a general term for certain types of skin disease, rather than a particular condition, and the Talmud maintains a similar view, arguing that tzaraath referred generally to any disease that produces sores and eruptions on the skin.
Investigations of keratins extracted from wool by reduction hydrolysis and by alkaline hydrolysis showed that their chemical compositions and secondary structures were similar to original wool. The keratin isolates were similar in amino acid, Amides I and II, and secondary structure to each other and to original wool.
Mineral wool insulation is made from molten glass, stone or slag (industrial waste) that is spun into a fibre-like structure and which creates a combination of properties that no other insulation material can match. There are two types of mineral wool product: glass wool insulation and stone wool insulation.Inorganic rock or slag are the main components (typically 98%) of stone wool. The remaining 2% organic content is generally a thermosetting resin binder (an adhesive) and a little oil.here are two types of mineral wool product: glass wool insulation and stone wool insulation.
