The rats that received more raspberry ketones burned more body fat and gained less fat tissue. A third study exposed fat cells in a test tube to raspberry ketones and found that the raspberry ketones stimulated the breakdown of the fat cells.
Notre Dame Cathedral in Paris was built by decree of Bishop Maurice de Sully in 1163 A.D. Like almost all medieval cathedrals, it took many years (and several successive Bisho â¦ ps) before it was finished. The average start to finish time of a Cathedral in that era was about a century.
Notre-Dame de Paris was among the first buildings in the world to use the flying buttress. The building was not originally designed to include the flying buttresses around the choir and nave but after the construction began, the thinner walls grew ever higher and stress fractures began to occur as the walls pushed outward.
