Todo e qualquer sistema de amortização por meio de prestações, constante ou não, uniformes ou não. Observe as seguintes premissas básicas:

I- Cada prestação é a soma de duas parcelas: a primeira é de juro, e a segunda de amortização.

II- A parcela de juro é sempre devida nos períodos em que existir prestação, podendo ser paga ou incorporada à principal.

III- Os sistemas de amortização de empréstimos são constituídos pela tabela SAC, SAM, PRICE e SACRE (este último adotado pela CEF).

DESKTOP HARD DRIVES SHRINK

When you say "3.5-inch hard drive," most people think of desktop PCs. But that presumption is changing as 2.5-inch hard drives find their way into desktop PCs and servers.

The trend first took hold with servers and enterprise hard drives, as 2.5-inch drives achieved high rotations per minute— 10,000 or 15,000 rpm-and better performance while generating less heat than 3.5-inch drives.

Now, consumer PCs are moving to 2.5-inch drives as well. A push toward smaller, design- and energy-conscious systems underlies manufacturers' inclusion of 2.5-inch drives in desktops. Mainstream desktop manufacturers use laptop components to build the compact PCs of the future, so it makes sense that some compact PCs have 2.5-inch hard drives inside. Even power desktops can get into the 2.5 inch game with Western Digital/s VelociRaptor hard drive, which zips at 10,000 rpm. Capacity is no longer an issue: 250GB to 320GB 2.5 inch drives are commonplace, and 500GB drives have begun shipping. But 2.5-inch drives won't take over on the desktop: Since 3.5-inch drives offer a better price/capacity ratio, 3.5-inch drives will continue to prevail.

According to the text, why will 3.5-inch drives continue to be used in desktops over the 2.5-inch drives?

O Programa de Estabilização Econômica, ou PlanoReal, foi concebido e implementado em três etapas: 1ª estabelecimento do equilíbrio das contas do governo, objetivando eliminar a principal causa da inflação; 2ª criação de um padrão estável de valor, a Unidade Real de Valor (URV), e 3ª emissão de uma nova moeda nacional com poder aquisitivo estável, o Real.

TRUTHS ABOUT NUCLEAR POWER

1. Today one-third of the world's people have no access to electricity. By 2050 demand for electricity will triple. Countries with large populations, like China and India, are turning to nuclear energy.

2. Nuclear reactors emit no greenhouse gases. Today's plants are preventing emissions of 2.5 billion tons of CO2 annually.

3. Nuclear is the only energy industry to take full responsibility for all its wastes. In countries using this form of power, radioactive wastes amount to less than 1% of total national wastes.

4. Reactors can now be used for desalination to meet the world's growing shortage of clean water. New reactors are expected to produce hydrogen and battery power for clean-energy cars.

5. Chernobyl spurred the creation of the World Association of Nuclear Operators. Today's reactors use a "defense in depth strategy," comprising multiple layers of backup safety systems, to prevent the release of radioactivity even under a worse-case scenario.

6. U.S. public support for nuclear energy has reached 70%, a record high.

According to the text Nuclear Power Energy is:

Em uma fazenda, a área cultivada permanece inalterada, enquanto novos tratores estão sendo adicionados na atividade produtiva. Cálculos indicam que o produto médio é da ordem de 5.000 toneladas de grãos por trator e que o produto marginal do último trator incorporado à produção é de 4.500 toneladas de grãos. A fazenda aumentará o seu produto médio por trator se:

I. Acrescentar mais um trator na produção.
II. Substituir um dos tratores utilizados atualmente por outro de menor custo operacional.
III. Retirar um trator da produção.
