1. Um programa adequado de manutenção corretiva corrige as causas dos defeitos apresentados pelos equipamentos, evitando situações catastróficas e viabilizando o planejamento e controle da manutenção.
2. A manutenção preditiva monitora determinados parâmetros de um sistema em operação para fazer prognósticos de vida útil residual dos componentes desse sistema, programando a intervenção antes de ocorrerem falhas.
3. A manutenção preventiva busca evitar paradas inesperadas de um equipamento, substituindo componentes em intervalos previamente definidos em função da vida útil total esperada desses componentes, mesmo que ainda apresentem condições de uso.
4. Na TPM (Total Productive Maintenance), o conceito de “quebra zero” pode ser sintetizado na seguinte frase: a máquina nunca pode parar.
Assinale a alternativa correta.
Biblis, Germany — Not since the grim period after World War II has Germany had significant blackouts, but it is now bracing for that possibility after shutting down half its nuclear reactors practically overnight.
Nuclear plants have long generated nearly a quarter of Germany’s electricity. But after the tsunami and earthquake that sent radiation spewing from Fukushima, half a world away, the government disconnected the 8 oldest of Germany’s 17 reactors — including the two in this drab factory town — within days. Three months later, with a new plan to power the country without nuclear energy and a growing reliance on renewable energy, Parliament voted to close them permanently. There are plans to retire the remaining nine reactors by 2022.
As a result, electricity producers are scrambling to ensure an adequate supply. Customers and companies are nervous about whether their lights and assembly lines will stay up and running this winter. Economists and politicians argue over how much prices will rise.
“It’s easy to say, ‘Let’s just go for renewables’, and I’m quite sure we can someday do without nuclear, but this is too abrupt”, said Joachim Knebel, chief scientist at Germany’s prestigious Karlsruhe Institute of Technology. He characterized the government’s shutdown decision as “emotional” and pointed out that on most days, Germany has survived this experiment only by importing electricity from neighboring France and the Czech Republic, which generate much of their power with nuclear reactors.
Then there are real concerns that the plan will jettison efforts to rein in manmade global warming, since whatever nuclear energy’s shortcomings, it is low in emissions. If Germany, the world’s fourth-largest economy, falls back on dirty coal-burning plants or uncertain supplies of natural gas from Russia, isn’t it trading a potential risk for a real one?
The world is watching Germany’s extreme energy makeover, as politicians from New York to Rome have floated their own plans to shut or shelve reactors.
The International Energy Agency, generally a fan of Germany’s green-leaning energy policy, has been critical. Laszlo Varro, head of the agency’s gas, coal and power markets division, called the plan “very, very ambitious, though it is not impossible, since Germany is rich and technically sophisticated”.
Even if Germany succeeds in producing the electricity it needs, “the nuclear moratorium is very bad news in terms of climate policy”, Mr. Varro said. “We are not far from losing that battle, and losing nuclear makes that unnecessarily difficult”.
The government counters that it is prepared to make huge investments in improving energy efficiency in homes and factories as well as in new clean power sources and transmission lines. So far, there have been no blackouts.
But Jürgen Grossmann, chief executive of the German energy giant RWE, which owns two closed reactors here in Biblis, about 40 miles south of Frankfurt, expressed skepticism. “Germany, in a very rash decision, decided to experiment on ourselves”, he said. “The politics are overruling the technical arguments”.

Assinale a alternativa que apresenta a sequência correta, de cima para baixo.
Design Patterns A design pattern is often posed as a question: how do we solve some design problem? However a design problem is, by its nature, nonspecific, and rarely has a single straight-forward answer. There might be several ways to solve the same problem, some better than others depending on the specific situation and the specific context of the problem. A design pattern is intended to share not just solutions but a better understanding of both the problem and how it might be solved.
Firstly, patterns have a well-defined structure. This consistent layout makes it easy to browse through a collection of patterns to find relevant help and then dive further into the material. The structure encourages the author of the pattern to think carefully about the knowledge they're sharing, whilst making the material more consistently accessible to a reader.
Secondly, unlike a tutorial or recipe which typically guides you through a single approach to solving a problem, patterns encourage discussion of related and complementary approaches. Design decisions are rarely clear cut, so it can be useful to understand the context in which a decision is made and the resulting trade-offs. Communicating these nuances is how we share knowledge rather than just fixes for a problem.
Consider the following sentence from the text: “Design decisions are rarely clear cut, so it can be useful to understand the context in which a decision is made and the resulting trade-offs”. Taking into consideration the underlined excerpt from the sentence, it is correct to say that design decisions are:
public class Misterio { public static long Misterio(long x) { if (x == 1) return 1; else return x * Misterio(x-1); } }
