Arqueólogos da Universidade de Tel Aviv afirmam ter descoberto as ruinas de fortificações construídas cerca de 2.700 anos atrás, em torno de um antigo porto da Assíria, numa região que hoje pertence a Israel. O achado confirma o relato bíblico sobre o assunto presente no capítulo 20 do Livro de Isaías.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
“As fortificações parecem proteger um porto artificial”, explica Alexander Fantalkin, líder das escavações no Ashdod-Yam, em um comunicado oficial. “Ao ser confirmado, será uma descoberta de importância internacional, o primeiro porto conhecido deste tipo no nosso canto do Levante”.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
A descoberta foi feita em um sitio arqueológico na cidade costeira de Asdode, ao sul da capital Tel Aviv. No centro das fortificações há uma parede de tijolos de barro medindo mais de 3 metros e meio de largura, chegando a 4,5 metros de altura em alguns pontos. A parede está coberta por camadas de lama e areia.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Quando foram construídas no século 8 a. C, as fortificações em forma de meia-lua defendiam uma área interior com cerca de sete hectares.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Segundo os relatos históricos, rei assírio Sargom II governou toda a parte sudeste da bacia do Mediterrâneo, incluindo o Egito e o Oriente Médio. Inscrições falam sobre um rei filisteu em Asdode, chamado Yamani, que tentou organizar uma revolta contra o Império Assírio. Os assírios responderam com força, assumiram o controle de Asdode, no ano 711 a. C e destruiu a cidade. Depois disso, o centro de poder foi estabelecido na área vizinha de Asdode-Yam, o local que está sendo escavado atualmente.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Baseado em escavações anteriores, o finado arqueólogo israelense Jacob Kaplan concluiu que os rebeldes construíram as fortificações em preparação ao ataque. Contudo, Fantalkin disse que a construção é grande demais para ter sido feito sob tais circunstâncias.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
O ataque de Sargom II contra Asdode é mencionado em Isaías 20, como um aviso para aqueles que apoiaram a rebelião. “Naquele dia o povo que vive deste lado do mar dirá: ‘Vejam o que aconteceu com aqueles em quem confiávamos, a quem recorremos para nos ajudar e livrar do rei da Assíria!”&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Ezequias, rei de Judá, ficou fora da luta, provavelmente a pedido do profeta Isaías, que nessa época andava nu e sem sandálias como uma forma de chamar atenção do povo para suas profecias.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Fantalkin e sua equipe dizem que os edifícios e paredes encontrados aparentemente são a reconstrução das fortificações anteriores, que provavelmente foram destruídas por um terremoto na segunda metade do século 2 a.C. Moedas antigas, vasos e outros artefatos dessa época foram encontrados entre as ruínas.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
Durante a época bizantina, o local era conhecido como Azoto Paralus. Uma cidadela chamada Kal’at Al Mina foi construída no local durante o período de dominação islâmica, em algum período entre os séculos 8 e 11. Em 1033, essa fortaleza foi seriamente danificada por um terremoto. É surpreendente que a parede com as inscrições achada agora tenha permanecido de pé depois de tanto tempo, tendo “sobrevivido” a tantos acontecimentos.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 1.21em; line-height: 1.45em; padding: 0px 0px 1.5em; vertical-align: baseline;&quot;&gt;
A última descoberta do tipo ocorreu em 1843, quando Paul Emile Botta escavou as ruinas do Palácio de Sargom II, o mesmo que é mencionado na parede encontrada agora. Durante muitos séculos grande parte dos relatos do Livro de Isaias foram considerados “não-históricos” por causa da falta de comprovações arqueológicas.&amp;nbsp;&lt;em style=&quot;border: 0px; font-family: inherit; font-size: inherit; font-variant: inherit; line-height: inherit; margin: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Com informações NBC News.&lt;/em&gt;&lt;/div&gt;

&lt;br /&gt;
Máximo divisor comum&lt;/div&gt;
&lt;/form&gt;
&lt;/div&gt;
&lt;/td&gt;&lt;/tr&gt;
&lt;/tbody&gt;&lt;/table&gt;
&lt;div&gt;
Vamos considerar a seguinte situação: desejamos recortar uma folha de papel retangular, medindo&lt;/div&gt;
&lt;div&gt;
30cm× 45cm, em pedaços quadrados todos com as mesmas dimensões. Como determinar as dimensões desses&lt;/div&gt;
&lt;div&gt;
pedaços de modo que eles tenham a maior área possível?&lt;/div&gt;
&lt;div&gt;
Uma solução: Se x é a medida dos lados destes quadrados, então x deve ser um divisor de 30 e também de 45.&lt;/div&gt;
&lt;div&gt;
Como os divisores positivos de 30 e de 45 são&lt;/div&gt;
&lt;div&gt;
D(30) = {1, 2,3,5,6,10,15,30} e D(45) = {1 ,3,5,9,15, 45}, x deve ser um elemento da interseção&lt;/div&gt;
&lt;div&gt;
destes dois conjuntos, ou seja, x∈ D(30)∩ D(45) = {1,3,5,15}.&lt;/div&gt;
&lt;div&gt;
Como queremos que os pedaços de papel tenham a maior área possível, devemos tomar x = 15 cm.&lt;/div&gt;
&lt;div&gt;
Nesse problema, o valor que tomamos para x é o maior inteiro positivo que divide 30 e 45&lt;/div&gt;
&lt;div&gt;
simultaneamente e, por isso, é chamado de máximo divisor comum de 30 e 45. Vamos denotá-lo por&lt;/div&gt;
&lt;div&gt;
mdc{30, 45}, ou seja, mdc{30, 45}= 15 .&lt;/div&gt;
&lt;div&gt;
O máximo divisor comum de dois números pode ainda ser definido assim:&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;
Definição: Sejam a e b inteiros, sendo pelo menos um deles não-nulo. Um inteiro positivo d é chamado&lt;/div&gt;
&lt;div&gt;
máximo divisor comum de a e b , que vamos denotar por mdc{a ,b}, se as duas condições seguintes são&lt;/div&gt;
&lt;div&gt;
satisfeitas.&lt;/div&gt;
&lt;div&gt;
1. d | a e d |b&lt;/div&gt;
&lt;div&gt;
2. se c ∈ Z é tal que c | a e c |b então c | d .&lt;/div&gt;
&lt;div&gt;
A condição (1) afirma que d é um divisor comum de a e b , enquanto a condição (2), além de dizer que d&lt;/div&gt;
&lt;div&gt;
é o maior divisor comum de a e b , também garante que d é divisível por qualquer divisor comum de a e b .&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Definição:&amp;nbsp;&lt;/div&gt;
&lt;div&gt;
Se mdc{a ,b}= 1 dizemos que a e b são relativamente primos ou primos entre si.&lt;/div&gt;
&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;
&lt;b&gt;Exemplo: &lt;/b&gt;Os números 9 e 40 são relativamente primos, pois 9 = 3² e 40 = 2³×5.&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;
&lt;b&gt;Observação:&lt;/b&gt; Dados dois inteiros a e b , às vezes é conveniente usar os mesmos primos para decompô-los em fatores primos. Isto é possível pondo expoente nulo em cada primo que aparece numa decomposição e não divide o número correspondente a esta decomposição. Isto também pode ser feito com mais de dois números.&lt;/div&gt;
&lt;/div&gt;
&lt;div&gt;
Exemplo: 18 = 2×32 e 40 = 23 ×5 mas podemos escrever 18 = 2×32 ×50 e 40 = 23 ×30 ×5 .&lt;/div&gt;
&lt;/div&gt;
