Based on an approach reported by Peter Steponkus and colleagues at Cornell University in 1990 , vitrification was accomplished by chilling the embryos to 205 degrees Celsius very rapidly ( 100,000 degrees per minute ) to " outrace " the lethal consequences and by using up to 8 times the normal amount of cryoprotectant ( ethylene glycol ) to dehydrate the cells and vitrify the water . A wind turbine typically takes only a few months ( 3-8 , depending on the average wind speed at its site ) to " pay back " the energy needed for its fabrication , installation , operation , and retirement . If he had belonged to the present generation he would , under the circumstances , have fallen into one of the besetting sins of England in these days - - the tendency ( to borrow an illustration from the stage ) to " strike an attitude " in the presence of a social emergency . The person seeking treaty benefits must also satisfy the " base erosion test , " which requires that less than 50 % of the person 's gross income for that taxable year be paid or accrued , directly or indirectly , in the form of deductible payments ( deductible in that person 's country of residence , but not including arm 's length payments in the ordinary course of business for services or tangible property ) to " bad " persons .
