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.

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.

Dada uma função com domínio D, ela possui inversa se, e somente se, for bijetora. Partindo dessa premissa, nem todas as funções trigonométricas possuem inversas em seus domínios de definição, já que para um valor da função correspondem infinitos valores de
x (x = 2kπ, k ∈ Z). Porém nós podemos tomar subconjuntos desses domínios D para gerar novas funções que possuam inversas.
Vejamos: A função inversa de f, denominada arco cujo seno, definida por f -1 : [ -1; +1] → [ -π/2; + π/2] , é denotada por f -1 ( x ) = arcsen ( x ) e a função inversa de g, denominada arco cujo cosseno, definida por g-1 : [ -1 ; + 1] → [ 0 ; π ] , é denotada por g-1 ( x ) = arccos ( x ). Sendo assim, podemos afirmar que os gráficos das funções f -1 (x) e g-1( x ) são, respectivamente,

O tempo de reação do corpo a um estímulo inicia-se com uma mensagem que é enviada ao cérebro e termina quando o cérebro envia outra mensagem para o corpo executar a reação física. Esse tempo de reação varia de uma pessoa para outra, do ambiente, do nível de estresse da pessoa, etc. Em média, para os motoristas após 6h de trabalho, podemos adotá-lo como sendo por volta de 0,25 segundos. Uma pessoa,adepta da “direção perigosa”, pode demorar até 3,25 segundos para pegar o telefone celular e atender uma ligação, tempo este em que ela não estará com a atenção voltada para o trânsito à sua frente. Considere que, após completar a ligação, ela levante a cabeça e veja algo inesperado a certa distância à frente e freie bruscamente o carro. Estando o carro a uma velocidade constante de 126 km/h e supondo que a velocidade do veículo se reduza uniformemente à razão de 8,75 m/s em cada segundo a partir do momento em que o freio foi acionado, podemos dizer que o carro percorreu, durante o intervalo de tempo sem a devida atenção do motorista ao transito até a parada total do veículo, uma distância aproximada de

O menor intervalo de tempo para que o cérebro humano consiga distinguir dois sons que chegam ao ouvido é por volta de 10-1s. Isso ocorre porque o ouvido humano só consegue captar e processar (ou seja, distinguir) sons produzidos em um intervalo maior que um décimo de segundo devido à persistência auditiva, o que gera o fenômeno conhecido como reverberação. Adotando a velocidade do som como 340 m/s em um local com um grande obstáculo, qual será a distância D máxima que uma pessoa, frontalmente ao obstáculo, deva estar para que ocorra a reverberação quando ela gritar “olá”?

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).
