A instrução paulista à época da Guerra do Paraguai (1864-1870)

This study aimed to analyze the Paraguayan War's impact on public education in the province of São Paulo in the period that lasted the conflict (1864-1870). Between 1864 and 1870 the area now known as South America experienced its greatest armed conflict. Brazil, Argentina and Uruguay declared war against Paraguay. Brazilian governors began to conceive the Empire as superior to the Paraguayan nation, which for them, was a non-civilized country. They understood that to maintain civilization and follow the progress, they needed to develop their education. The Empire mobilized men of any part of its territory. Some left for the war voluntarily and others were forced. Along that current War, the recruitment had become increasingly difficult, leading entire families moving, teachers and students to leave the school and the city. The paulistas teachers have been turning to the patriotic past of the province in which he was proclaimed the independence of the Empire. Civilization and progress, present at the leaders speeches were reflected in the São Paulo social practices that culminate in the notion of patriotism, also reflected in the education of children and youth of the period.

Estudo da variabilidade da deriva vertical do plasma ionosférico sobre a região de Natal/RN, Fortaleza/CE e Cachoeira Paulista/SP para alguns casos de tempestades magnéticas de abril a setembro de 2000

In this work are presented the results of research on the variation of vertical plasma drift from the F layer that commonly occurs during the period close to the going down of the sun (between 21UT - 22UT), and consisting of an increase in the F layer in time of day and a drop at night on the cities of Natal / RN (The 33.7º, 5.6º S), Fortaleza / CE (38.45º O, 3.9º S) and Cachoeira Paulista / SP (45.0ºO, 22.7º S ). Thus, data was used (ionograms) virtual height t ( h' ) as a function of the frequency F for the layer of the ionosphere. These data were collected through ionossonda type CADI (Canadian Advanced Digital Ionosonde) to the cities of Natal and Fortaleza, and the Digisonde DPS to the town of Cachoeira Paulista. They considered only the data available 2000 maximum solar year. With the virtual height ( h' ) data reduced in the frequencies of 6MHz and 5MHz, the next step was to calculate. The results showed that the variability of the vertical drift rate F ionospheric layer periods of magnetic storms is related both to the penetration of the electric fields as the disturbance dynamo electric fields.
