EL TIGRE, Venezuela — Thousands of workers are fleeing Venezuela’s state-owned oil company, abandoning once-coveted jobs made worthless by the worst inflation in the world. And now the hemorrhaging is threatening the nation’s chances of overcoming its long economic collapse.

Desperate oil workers and criminals are also stripping the oil company of vital equipment, vehicles, pumps and copper wiring, carrying off whatever they can to make money. The double drain — of people and hardware — is further crippling a company that has been teetering for years yet remains the country’s most important source of income.

The timing could not be worse for Venezuela’s increasingly authoritarian president, Nicolás Maduro, who was re-elected last month in a vote that has been widely condemned by leaders across the hemisphere. Prominent opposition politicians were either barred from competing in the election, imprisoned or in exile.

But while Mr. Maduro has firm control over the country, Venezuela is on its knees economically, buckled by hyperinflation and a history of mismanagement. Widespread hunger, political strife, devastating shortages of medicine and an exodus of well over a million people in recent years have turned this country, once the economic envy of many of its neighbors, into a crisis that is spilling over international borders.

If Mr. Maduro is going to find a way out of the mess, the key will be oil: virtually the only source of hard currency for a nation with the world’s largest estimated petroleum reserves. But each month Venezuela produces less of it. Offices at the state oil company are emptying out, crews in the field are at half strength, pickup trucks are stolen and vital materials vanish. All of this is adding to the severe problems at the company that were already acute because of corruption, poor maintenance, crippling debts, the loss of professionals and even a lack of spare parts.

Now workers at all levels are walking away in large numbers, sometimes literally taking pieces of the company with them, union leaders, oil executives and workers say.

A job with Petróleos de Venezuela, known as Pdvsa, used to be a ticket to the Venezuelan Dream. No more.

Inflation in Venezuela is projected to reach an astounding 13,000 percent this year, according to the International Monetary Fund. When The New York Times interviewed Mr. Navas in May, the monthly salary for a worker like him was barely enough to buy a whole chicken or two pounds of beef. But with prices going up so quickly, it buys even less now.

Junior Martínez, 28, who has worked in the oil industry for eight years, is assembling papers, including his diploma as a chemical engineer. His wife and her daughter left three months ago to earn money in Brazil. “I get 1,400,000 bolívars a week and it isn’t even enough to buy a carton of eggs or a tube of toothpaste,” Mr. Martínez said of his salary in bolívars, Venezuela’s currency.

Mr. Martínez’s father, Ovidio Martínez, 55, recalled growing up here when the oil boom began. He cried as he spoke of his son’s determination to leave the country. “You watch your children leave and you can’t stop them,” the elder Mr. Martínez said, fighting back tears. “In this country, they don’t have a future.”

In El Tigre, hundreds of people stood in line one recent morning outside a supermarket, many waiting since the evening before to buy whatever food they could.

Em astronomia, meridianos e paralelos são linhas circulares localizadas na superfície da esfera terrestre, assim definidas:

I. Considera-se o globo terrestre como uma esfera cuja medida do diâmetro é d Km.

II. São fixados, na superfície terrestre, dois pontos N e S, diametralmente opostos, denominados de polo norte e polo sul. A reta que contém os pontos N, S e o centro da esfera é denominada de eixo terrestre.

III. Meridianos são todas as circunferências na superfície terrestre que contêm os pontos N e S.

IV. Paralelos são todas as circunferências resultantes da interseção dos planos perpendiculares ao eixo terrestre com a superfície terrestre.

Considerando M, P e Q pontos que dividem o segmento NS em quatro partes iguais, sendo P o centro da esfera terrestre, pode-se afirmar corretamente que o comprimento de cada um dos dois paralelos (do que está contido no plano perpendicular ao eixo terrestre e que contém o ponto M, e do outro contido no plano perpendicular ao eixo terrestre que contém o ponto Q) é igual a
