In the case of severe acute aortic insufficiency, all individuals should undergo surgery, if there are no absolute contraindications (for surgery). Individuals with bacteremia with aortic valve endocarditis should not wait for treatment with antibiotics to take effect, given the high mortality associated with the acute AI.
Where the ground rod is located far from the main electrical panel, thicker No. 3 wire may be required. In areas where codes require two ground rods because of high electrical resistance in the soil, the rods must be spaced at least 6 feet apart and interconnected by a buried jumper wire.
How far apart should I place my control joints? We recommend that you place your control joints no more than 2 times in feet the thickness in inches of the slab. (4â slab 8â joint spacing) These joints must be a minimum of Â¼ the depth of the slab. (1â on 4â slab) Also, it is recommended that you attempt to design panels that are as square as possible. (Avoid exceeding 1.25 times square) For more information see Joints in Concrete Slabs on Grade.
