41. Fractionating columns are widely used in the chemical process industries where large quantities of liquids have to be distilled.42. Figure 3 depicts an industrial fractionating column separating a feed stream into one distillate fraction and one bottoms fraction. 43. Figure 5 : Section of fractionating tower of Figure 4 showing detail of a pair of trays with bubble caps 44. Fractionated radiation dosage increases the risk of mucositis to > 70 % of patients in most trials.45. DARPA called for open source development of the networking and communications protocols and interfaces for the fractionated spacecraft modules. 46. By 1934, Coutard had developed a protracted, fractionated process that remains the basis for current radiation therapy. 47. As noted above, in some cases the land is so highly fractionated that it can never be made productive. 48. :Perfume # Concentration _ levels says ethanol or ethanol and water or jojoba, fractionated coconut oil or wax. 49. When fractionated by agarose or acrylamide gel electrophoresis, the digested PCR products will give readily distinguishable patterns of bands. 50. Once an individual protein is isolated, it needs to be digested and fractionated for further analysis by a spectrometer.
