The starfish (commonly as a sea star) is generally found with 5 arms that are attached to a central disc. This central disc is the activity center of the starfish and also contains the mouth of the starfish.he starfish (commonly as a sea star) is generally found with 5 arms that are attached to a central disc.

The average moisture content of modern softwood timbers in dry buildings is generally in the range of 12â15%, and heating systems may reduce this to a far lower level. There is, therefore, no prospect of a dry rot infestation developing in a building that has been properly designed, constructed, and maintained.
Loss on Drying (LOD) The classic laboratory method of measuring high level moisture in solid or semi-solid materials is loss on drying (LOD). In this technique a sample of material is weighed, heated in an oven for an appropriate period, cooled in the dry atmosphere of a desiccator, and then reweighed. If the volatile content of the solid is primarily water, the LOD technique gives a good measure of moisture content.
