41. The group has recently begun a project to build a fractionation plant in Nova Scotia. 42. The economic consequences of fractionation are severe. 43. The operation commenced plasma fractionation in 1952. 44. Another variation involved a heat ethanol fractionation . 45. In 1875 Heaney obtained a colorless liquid ( Oreodaphenol ) via fractionation under reduced pressure. 46. Most commonly, the presence of a phycotoxin is verified by bioassay-guided fractionation . 47. Normally, the difference in fractionation costs outweighs this advantage when comparing overall utility costs. 48. During his career at Vermont, Novikoff had successfully developed a technique of cell fractionation . 49. Another endogenic process used to explain the hemispheric dichotomy is that of primary crustal fractionation . 50. The liquid-vapor equilibrium fractionations for hydrogen and oxygen isotopes are temperature-dependent:
