Wind turbines convert wind energy to electricity for distribution. Conventional horizontal axis turbines can be divided into three components: 1  The rotor component, which is approximately 20% of the wind turbine cost, includes the blades for converting wind energy to low speed rotational energy.
Blood Banking & Donation. Blood banking refers to the process of collecting, separating, and storing blood. The first U.S. blood blank was established in 1936. Today, blood banks collect blood and separate it into its various components so they can be used most effectively according to the needs of the patient.
Using a testing assay with a detection limit of 1000 RLA, potentially infectious HCV was recovered from dried blood spots stored at 37oC for up to seven days. At temperatures of 4oC and 22oC, replicating HCV was recovered for up to six weeks of storage. The infectivity of the dried spots declined sharply during the first two weeks of storage at these temperatures.
