Discovery, Appearance and Meaning of Cave paintings in France and Essay

Discovery, Appearance and Meaning of Cave paintings in France and Spain - Essay Example The essay "Discovery, Appearance and Meaning of Cave paintings in France and Spain" explores Cave paintings in France and Spain. Nearly two hundred cave paintings have been discovered so far in France and Spain, and they still continue, as the recent discovery of cave paintings in the Vilhonneur forests, in the Charente region of western France suggest. However, the cave paintings in the Lascaux Cave of Montignac, in the Dordogne region of southwest France, and Altamira, in northwest Spain, still remain the more significant examples of pre-historic cave paintings. The initial discovery of the caves, and the paintings at Altamira were made in the later half of the nineteenth century by accident. In 1868 a hunter’s dog chasing a fox fell among some boulders, and the hunter, in attempting to rescue the dog discovered the entrance to the famous cave. The cave paintings took more than a decade later to be discovered, again by accident. The owner of the estate in which the cave was located was an amateur archeologist. His young daughter accompanied him on one of his trips into the cave, to look for tools, in 1879. She looked up at the ceiling, and became the first person in modern times to espy the herd of red animals painted across the ceiling. Initially these paintings were not accepted as pre-historic paintings, and believed to be forgeries a mere twenty years old. In the beginning of the twentieth century efforts of the French priest Henri Breuil made the world aware of this finest example.

There are four major geometric flow configurations for radiators. The geometry of the fin determines the amount of heat lost from the car engine to the atmosphere and hence determines the performance of a car radiator. Car radiator normally uses crossflow two-stream geometry. The heat transfer performance of a radiator can be determined by calculating the number of Nusselts. The value of Nusselt number increases with increase in as the Reynolds number. The performance of the heat exchanger increases with increase in the number of Nusselts. As such, the number of Nusselts is directly proportional to the performance of the heat exchanger. This assignment is makes an invaluable contribution to the UniSA graduate qualities by equipping the graduates with essential knowledge for manufacturing radiators, particularly car radiators and developing innovative ideas to improve the radiator, which is one of the most crucial components of the car
