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.
Blood bank: : A place where blood is collected from donors, typed, separated into components, stored, and prepared for transfusion to recipients. A blood bank may be a separate free-standing facility or part of a larger laboratory in a hospital.Separation of blood: Typically, each donated unit of blood (whole blood) is separated into multiple components, such as red blood cells, plasma and platelets.Each component is generally transfused to a different individual, each with different needs.An increasingly common blood bank procedure is apheresis, or the process of removing a specific component of the blood, such as platelets, and returning the remaining components, such as red blood cells and plasma, to the donor.torage of blood: Each unit of whole blood is normally separated into several components. Red blood cells may be stored under refrigeration for a maximum of 42 days, or they may be frozen for up to 10 years.
