Q: Today, the Eiffel Tower, which serves an important role in television and radio broadcasts, is considered an architectural wonder. It attracts more visitors than any other paid tourist attraction in the world. The Eiffel Tower was designed by the French engineer and bridge builder Alexandre Gustave Eiffel for the Paris Exposition of 1889. The tower is 300 m high and consists of an open iron framework making it the highest manmade structure in the world at the time. It was almost not built. After being awarded the contract to build the tower, Eiffel discovered that the Exposition Committee would only provide about a quarter of the money needed to construct it. Eiffel himself would have to finance the balance. He thought of a deal that would make him a very rich man. He agreed to independently find the people to fund his tower but he wanted to be the only one to control of the tower and he wanted the profits for twenty years. They agreed. To everyone's surprise, including Eiffel, the tower was paid off in the first year. The deal that Eiffel came up with was probably what saved the tower from destruction. A Committee of Three Hundred was formed and they demanded an end to its building. Many members of the committee said, "They have only put up the framework of this monument, It has no skin." Many sculptors and architects protested , in the name of threatened French art and history, about the useless Eiffel Tower, in the heart of their capital. It is built of iron, which is an inferior material, and a single beam of it is unable to support large stresses. That is why the tower appears over-engineered by today's standards. Though, from this very weakness, its simple beauty can be found. If you look at the tower, the structure of it sort of copies the biological cellular structure of a plant.

A: What was the Eiffel Tower originally designed for?

Q: The overlap between symptoms of PTSD and MDD is substantial. PTSD symptoms arise after a traumatic experience and the trauma is present in all of the diagnostic clusters. In individuals who have experienced a trauma a long time before, it is difficult to establish the exact moment of onset of their symptoms in relation to the trauma suffered. We proposed to raise awareness among operators who may encounter this problem, with the aim of providing them with valuable help in order to achieve a correct differential diagnosis. A sample of subjects suffering from PTSD without comorbidity was assessed to confirm the diagnosis and the severity of post-traumatic symptoms. The Kruskal-Wallis test was used to compare any modifications in the parameters analyzed through the Davidson Trauma Scale with the presence and severity of depressive symptoms as evaluated by the Hamilton-D scale. Half of the PSTD patients recruited showed values of HAM-D > 18, although an active Major Depressive Episode was clinically excluded. Symptom of "numbing", despite being different from the apathy experienced in depression, is identified as a depressive symptom by the HAM-D. Giving prevalence to depressive symptoms may be misleading for diagnosis and may ultimately result in inappropriate treatment.

A: Symptoms of which disorder are evaluated with the Davidson Trauma Scale?
