           Roraima  also differs from other areas of the Amazon, given the timid way in which corporate capital has ventured into the region. Despite its natural riches, there are no large-scale mining or timber operations, and local industries are embryonic. Resulting from the mild stage of capitalist exploration, and relatively recent human occupation, the number and intensity of conflicts over regional resources are substantially smaller.
          Migration represented a leading role in the territorial, political and cultural formation of Roraima. During the 1970s and 1980s the state received a considerable influx of migrants from the North and Northeast regions of Brazil, especially from Ceará, Maranhão, Pará and Amazonas states. Overtime migration flows were perpetuated due to the workings of very active migrant social networks, linking very specific communities at origins and destinations. Internally, the city of Boa Vista has played a paramount role attracting immigrants from other states and then redistributing them to other municipalities. The importance of Boa Vista can be grasped from a quick examination of Roraima's urban network, where it exerts the role of a primate city in a highly unbalanced system.
             The tremendous influx of migrants over the 1970s and 1980s had a direct impact in the creation of new municipalities, promoting regional development and economic change, which, in turn, fueled renewed migratory flows. The 1990s and 2000s witnessed an augmentation of such moves projecting an inversion in terms of importance of inter and intrastate moves in future years. After all, interstate long distance moves have historically dominated Roraima's migration system; nonetheless, over the last decades intrastate migration has grown at a much faster pace than longer moves.
               In the near future Roraima is likely to continue drawing migrants from traditional areas given the organic nature of migrant social networks and its tendency to remain active over time. On the other hand, new migration flows are likely to arise and intensify as regional development will create economic opportunities for many, intensifying formal and informal communication channels. Within this context, the service sector, especially the public administration system will allure urban bound migrants from various Brazilian cities. However, one cannot deny the fact that Roraima remains an active agriculture frontier, where the perspective of acquiring a free plot of land is still viable. Thus, Roraima will still receive large waves of landless peasants in the near future, most likely from traditional source areas. Nevertheless, in order to become a valid alternative for the Brazilian poor, it is imperative that current abandonment rates within colonization projects are diminished, preventing them from turning into a demographic void, while the peripheral areas of the encroaching urban places become increasingly plagued with poverty.

    Numa aula de Física, o Professor Carlos Heitor apresenta a seus alunos esta experiência: dois blocos – um de alumínio e outro de ferro –, de mesma massa e, inicialmente, à temperatura ambiente, recebem a mesma quantidade de calor, em determinado processo de aquecimento.

    O calor específico do alumínio e o do ferro são, respectivamente, 0,90 J / (g °C) e 0,46 J / (g °C).

    Questionados quanto ao que ocorreria em seguida, dois dos alunos, Alexandre e Lorena, fazem, cada um deles, um comentário:

    • Alexandre: “Ao final desse processo de aquecimento, os blocos estarão à mesma temperatura.”

    • Lorena: “Após esse processo de aquecimento, ao se colocarem os dois blocos em contato, fluirá calor do bloco de ferro para o bloco de alumínio.”

    O Instituto de Pesquisas Espaciais (INPE) realiza estudo sobre o desmatamento da floresta amazônica por meio de dois programas que analisam fotos de satélites: o Prodes e o Deter. Esses sistemas apresentam algumas limitações como o fato de imagens não serem captadas em dias nublados (dependendo da época do ano), ficando assim parte do território amazônico sem ser verificado. O gráfico acima mostra dados da área total de desmatamento por ano, baseado nas análises desses sistemas.

    Read the following passage of “The Dinner”, by Clarice Lispector, and answer question.


    “I leaned over my meal, lost. When I finally managed to confront him from the depths of my pallid face, I observed that he, too, was leaning forward, his elbows resting on the table, his head between his hands. And obviously he could bear it no longer. His bushy eyebrows were touching. His food must have lodged just below his throat under the stress of his emotion, for when he was able to continue, he made a visible effort to swallow, dabbing his forehead with his napkin. I could bear it no longer, the meat on my plate was raw… and I really could not bear it another minute. But he – he was eating.

    The waiter brought a bottle in a bucket of ice. I noted every detail without being capable of discrimination. The bottle was different, the waiter in tails, and the light haloed the robust head of Pluto which was now moving with curiosity, greedy and attentive. For a second the waiter obliterated my view of the elderly gentleman and I could only see his black coattails hovering over the table as he poured red wine into the glass and waited with ardent eyes – because here was a surely man who would tip generously, one of those elderly gentlemen who still command attention… and power. The elderly gentleman, who now seemed larger, confidently took a sip, lowered his glass, and sourly considered the taste in his mouth. He compressed his lips and smacked them with distaste, as if the good were also intolerable. I waited, the waiter waited, and we both leaned forward in suspense. Finally he made a grimace of approval. The waiter curved his shiny head in submission to the man’s words of thanks and went off with lowered head, while I sighed with relief.

    He now mingled gulps of wine with the meat in his great mouth and his false teeth ponderously chewed while I observed him… in vain. Nothing more happened. The restaurant appeared to radiate with renewed intensity under the tinkling of glass and cutlery; in the brightly lit dome of the room the whispered conversation rose and fell in gentle waves; the woman in the large hat smiled with half closed eyes, looking slender and beautiful as the waiter carefully poured the wine into her glass. But now he was making another gesture.”
