act turns first on the question of whether the claimant is an employee of the person or entity against whom the claim is brought there are a number of different statutory definitions for the nouns employer and employee in the act but no definition for the verb employ
Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).Silicate minerals also often contain other elements, such as calcium, iron, and magnesium.ilicates are minerals that contain silicon atoms bonded to oxygen atoms.

A group of minerals containing various amounts of the elements Silicon and Oxygen. The Silicates are the largest group of minerals. The construction component of all Silicates is the tetrahedron, which is one Silicon atom equidimensionally placed around four Oxygen atoms. These tetrahedrons, when combined with other molecules or tetrahedrons form the different Silicate minerals.
