  mixture of   fragrant   essential oils   or   aroma compounds   (fragrances),   fixatives   and   solvents , usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable   scent .   The 1939   Nobel Laureate   for Chemistry,   Leopold Ružička   stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of   organic chemistry   as regards methods, systematic classification, and theory. Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as  vanillin  or  coumarin , which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics.

  Home lifts are compact lifts for 2 to 4 persons. Unlike   hydraulic lifts   or traditional " gear   and   counterweight " operated elevators, a home lift doesn't require additional space for machine room, over head, or pit, making it more suitable for domestic and private use. Often,   maintenance   costs are also lower than a more conventional lift. The driving system for a home lift is often built inside the lift structure itself and features a  screw , an  electric motor , and a  nut  mounted behind the  control panel  of the lift's platform; it is thus referred to as a "screw and nut" system. When the lift is operated, the  engine  forces the nut to  rotate  around the screw, pushing the lift up and down. Most home lifts come with an open  platform  structure to free even more space and grant access from 3 different sides of the platform. This requires all producers to include specific  safety mechanisms  and, in some  countries , to limit the travel s
