                             Brazil turns to drones to protect Amazon
                  By Joe Leahy in Alta Floresta, Mato Grosso. April 21,2014.

       Brazilian municipalities are turning to drones as they prepare to implement a tough new law designed to save the Amazon from total deforestation.
      Municipal authorities in the Amazon region, ...........1 ............. of which covers double the size of Scotland, are looking to use drones to map properties and monitor whether farmers and others are maintaining the minimum of forest cover required under the new forest code.
     “With the acquisition of a drone, we would have a better result, we would have a panoramic view of how this process of recuperation is progressing," said Gercilene Meira, a specialist with the state   environmental secretariat in the municipality of Alta Floresta, in Mato Grosso state. “We have done some tests using balloons but it was not sufficient."
      Passed in 2012, Brazil's forest code was hailed as a breakthrough in the country's efforts to protect the Amazon while maintaining its emergence as an agricultural power. It is already one of ...........2 ............. exporters of sugar, coffee, soya beans and beef.
      The law requires farmers in the Amazon to preserve up to 80 per cent of the forest on their land as well as protect springs and rivers. Those who violated previous restrictions on deforestation are required
to recuperate parts of the lost vegetation on their lands.
      The need for the new law was highlighted last year, when deforestation of the Amazon increased for the first time in several years.

                                                                                                                             Adapted from Financial Times According to the text, which of the following is Not true?

                    Gabriel García Márquez was a Literary Giant
                               With a Passion for Journalism
                      By Karla Zabludovsky Friday, April 18,2014

      The late Gabriel García Márquez holds a special place in the hearts of journalists.
      Like Charles Dickens, Mark Twain and Ernest Hemingway — or contemporaries like Pete Hamill and Tom Wolfe — García Márquez, a titan of 20th century literature, honed his writing skills as a reporter
before he became a celebrated novelist.
      Even as his literary star rose, García Márquez, known colloquially across Latin America as Gabo, spoke proudly, tenderly and frequently about journalism.
      “Those who are self-taught are avid and quick, and during those bygone times, we were that to a great extent in order to keep paving the way for the best profession in the world… as we ourselves called
it," said García Márquez during a speech about journalism at the 52nd Assembly of the Inter American Press Association in 1996.

           CORREÇÃO DE NEWTON À TERCEIRA LEI DE KEPLER

      As leis de Kepler são cinemáticas e foram fundamentais para permitir que Newton descobrisse as leis da mecânica e da gravitação.Com essas leis, Newton mostrou que a terceira lei de Kepler necessitava de uma pequena correção. Com essa correção, a terceira lei de  Kepler se escreve:



Ou seja, a razão entre o cubo das distâncias médias dos planetas à estrela e o quadrado dos períodos dos movimentos é aproximadamente a mesma para todos os planetas. Ela depende também da massa m do planeta, que aparece somada à massa M da estrela no  fator (M + m).

O Sol tem cerca de 1000 vezes mais massa que o maior planeta do nosso Sistema Solar e o texto nos informa que a “Terceira Lei de Kepler" não está totalmente correta embora, na prática, para o nosso sistema solar, essa correção não seja utilizada. O motivo para não fazer a correção é que

A partir do monóxido de carbono e hidrogênio, em determinadas condições, é possível obter metanol conforme a equação química abaixo:

Moléculas orgânicas de elevada massa molecular, denominados dePOLÍMEROS, estão sendo cada vez mais empregadas nas indústrias, produzindo materiais mais leves, com mais resistência e de menor custo que os tradicionais. Para se obter um POLÍMERO, são utilizadas várias moléculas menores denominadas MONÔMEROS.
Abaixo são apresentados alguns MONÔMEROS e seus respectivos POLÍMEROS.
