Spiritual gifts are not innate, natural talents, like an ear for music or the ability to draw, but rather they are empowerments that the Holy Spirit gives to a believer to minister to the body in ways that were not possible by mere natural effort apart from the Holy Spirit.
In the design of a dam, the first step is the determination of various forces which acts on the structure and study their nature. Depending upon the situation, the dam is subjected to the following forces: 1. Water pressure. 2. Earthquake forces. 3. Silt pressure. 4. Wave pressure. 5. Ice pressure. 6.
a dam in which the water pressure of the headrace, which is absorbed by the pressure floor (in the form of plates or vaults), is transmitted to buttresses and the foundation.Buttress dams are constructed primarily from concrete and reinforced concrete.oth fixed and spillway buttress dams are built. In comparison with massive gravity dams, buttress dams (especially the multiple-arch type) produce savings of 40 percent and more in concrete and costs, depending on the design and local conditions. The height of buttress dams sometimes exceeds 100 m.
