DISPOSE OF NUCLEAR WASTE IN SPACE

Fifty years into the atomic age, there is still no way to dispose of thousands of tons of high-level nuclear waste. Thirty-eight years into the space age, there is still no inexpensive, reliable means to launch payloads to orbit. Four years after the breakup of the Soviet Union, tens of thousands of highly skilled engineers and scientists are discovering that the end of the Cold War has also ended their careers.

Are these three regrettable, but isolated problems or are they an opportunity to provide a better future while opening up the promise of space? lt is time to reconsider disposing of high-level nuclear waste in space, instead of underground.

[....................................................................................]

Nuclear waste has been the province of geologist and mining engineers for years, and their focus is under the Earth's surface. But the aerospace community, focused on satellite and manned flight, did not like the image of space as a garbage dump. Both communities now have reason to reconsider space disposal of nuclear wastes.

Space disposal will permanently remove the burden and responsibility of high-level radioactive waste from future generations. And it will provide a justification for massive investment in much-needed space technologies. Now that the U.S — Soviet rivalry that fed much of the space race is gone, space exploration and development increasingly have to be justified on their own merits. The immediate and clear benefits of shipping nuclear wastes to space may make space disposal more politically attractive than a manned mission to Mars.[..................................................................... ].

Chaining channels

The latest version of Sony’s tiny portable television, FDL-22 Watchman Color TV with Straptenna, is ergonomically designed for easy holding and viewing. A 5.6-cm liquid-crystal-display screen — the smallest to date – emits an impressively sharp picture. The signal is pulled in by a strap/antenna worn around the neck; it makes use of the water content of the human body to help with the reception.

Super food for skinnies

Scientists discovered 20 years ago that butter could be rendered more benign to the heart if, in a bit of molecular manipulation, the food’s fatty acids were rearranged. The resulting concoction, which tastes like butter but doens’t clog arteries, is nearly ready for commercial use. Playing around with several recipes, Dr. Edward Mascioli and a team at the Harvard Medical School have baked modified butter into guilt-free muffins and cookies that they hope will lower snackers’ blood-cholesterol levels. The stuff is being tested with a group of consumers eating regular goodies for five weeks followed by five weeks more on the virtuous kind. Medical Foods, a Canadian firm, plans to bring a line of such treats to market after that experimental phase is over.

Play tripper

Renault’s commuter car of the future is called Ludo (Latin for I play), though customers aren’t likely to go joyriding in anything similar for several years. But as far as the prototype is concerned, the designers have achieved a playful combination of practicality and efficiency in a city car. One of three designs being studied by Renault, the Ludo has twin sliding doors, giving as many as five passengers easy access, and fold-down seats that allow plenty of space for stowing paraphernalia. It features a peppy 1.15-liter engine fueled by clean-burning petroleum gas (a mixture of butane and propane). Top speed: about 150 km/h.

• holding = manuseio

• screen = tela

• to date = até o momento

• sharp = preciso

• to wear, wore, worn = usar

• neck = pescoço

II. O Ludo, da Renault, destina-se a ser um meio de transporte eficiente nos centros urbanos.

III. As palavras invention, block e food no texto “Superfood for skinnies” podem ser consideradas sinônimos de concoction, clog e goodies, respectivamente.

ENGINEERING: Chemical Engineer

Pharmaceutical companies will spend $ 12.9 billion in 1998 seeking the next wonder drug -- almost twice what they spent in 1990. Overall, private research-anddevelopment budgets ( I ) $ 99.3 billion last year, up 21.7 percent in five years. Much of that investment pays chemical engineers, who put the right shade of rose in lipstick, the mouthwatering taste in fat-free cheese, the air-synthetic rubber - in Air Jordans. The Bureau of Labor Statistics (…lI…) that demand in R&D by 5 percent a year until 2005. At Pfizer Inc., chemical engineers make up to 20 percent of the manufacturing work force in the country.

II. Os engenheiros químicos aos quais o texto se refere desenvolvem produtos como batons e tortas dietéticas de queijo.

III. A demanda por profissionais para a área de pesquisa e desenvolvimento deve crescer em média cinco por cento até o ano 2005.

está(ão) correta(s)

Considere as afirmações sobre polígonos convexos:

I) Existe apenas um polígono cujo número de diagonais coincide com o número de lados.

II) Não existe polígono cujo número de diagonais seja o quádruplo do número de lados.

III) Se a razão entre o número de diagonais e o de lados de um polígono é um número natural, então o número de lados do polígono é ímpar.

Então:

A soma das raízes da equação !$ \sqrt3 \tan x - \sqrt3 \, \sin \, 2x+ \cos \,2x=0 !$, que pertencem ao intervalo !$ [0,2 \pi] !$, é:

A inequação

!$ 4x\, \log_5 (x + 3) \ge (x^2 + 3) \log_{\large 1 \over 5} (x + 3) !$

é satisfeita para todo !$ x ∈ S !$. Então:

Seja ABC um triângulo isósceles de base BC. Sobre o lado AC deste triângulo considere um ponto D tal que os segmentos AD, BD e BC são todos congruentes entre si.

A medida do ângulo !$ B\hat{A}C !$ é igual a:

Seja a um número real tal que o polinômio

!$ p(x) = x^6 + 2x^5 + ax^4 – ax^2 – 2x – 1 !$

admite apenas raízes reais. Então:
