later‚ scientists and paleontologists have found they are very much like modern human‚ but with different physical appearances. When comparing the modern human skeleton to the Neanderthal’s‚ one would be able to notice some differences between that of a modern human and a Neanderthals. One very notable difference between the two skeletons was that Neanderthals’ were more robust than that of a human‚ due to the fact that they have been living in colder climate. For an example‚ compared to the legs

STEAM TURBINES A steam turbine is a prime mover which converts heat energy into mechanical energy. In a conventional steam turbines cycle‚ water is used as the working fluid. The water is heated in a boiler by burning fuel. It evaporates into steam which is expanded in a turbine where mechanical power is generated. The steam generated is of high temperature and high pressure. The temperature is often in the 450 to 540 degrees centigrade range. The pressure ranges between 60 and 120 bar. The

like we talked about in class. What I saw in examples of human skeletons was how our bones developed and grew. In the exhibit‚ I witnessed the first skeleton ever found‚ called Lucy. She was incredibly small compared to modern day humans. There was a part in the exhibit that showed three progressive skeletons of humans overtime. The first skeleton was of a human‚ bent over‚ with large hands‚ feet‚ and a long face. The second skeleton had adapted to its environment‚ and had begun to walk on two feet
