Rotor and Nacelle Mass. Rotor mass trends are always complicated by quite different material solutions, choice of aerofoils and design tip speed, all of which can impact very directly on the solidity (effectively surface area) and mass of a blade. Table 3.3 shows blade mass of very large wind turbines. The introduction into Enerconâs E126 design of a jointed blade with a steel spar on the inner blade is a clear example of where blade technology is radically different from most other large blades. Table 3.3: Blade Mass of Very Large Wind Turbines.
Chemicals used in insecticides (chlorophe-. nothane), glue (toluene), and Stoddard solvent. (petroleum distillates) have also been associated with. aplastic anemia. Drugs. Chloramphenicol was, at one point, the most. common cause of drug-induced aplastic anemia in the. United States. Anticonvulsant medications, in particular. carbamazepine and hydantoins, are also associated with. the development of aplastic anemia.
agents have been associated with aplastic anemia, but it is difficult to prove whether there is a causal relationship, given the absence of conï¬rmatory cases. [3] Dapsone is a drug that is known to be associated with serious hematological ADR, including agranulocytosis, [4] hemolytic anemia and, [6, 7] more rarely, aplastic anemia. [8, 9] Aplastic anemia seen with dapsone may be either of two types; early or late. Early onset bone marrow toxicity is usually detected during or shortly after drug exposure, may be dose-related, and is usually reversible. Late onset aplastic anemia does not depend on the dose and duration of exposure, and is irreversible.
