Um vestibulando chega ao local de prova faltando 15 minutos para o fechamento dos portões e, como ainda tem tempo, decide comprar uma barra de chocolate. Ele sabia que havia uma padaria a algumas quadras dali, então se dirige ao estabelecimento, movendo-se com velocidade constante de 2 m/s, e chega ao local em 5 minutos. O vestibulando pega seu chocolate, alguns outros produtos e acerta com o caixa. Com isso, ele demora um pouco mais do que havia planejado, tendo gastado 8 minutos em sua compra.

Are any foods safe to eat anymore? The fears and the facts

Food was once seen as a source of sustenance and pleasure. Today, the dinner table can instead begin to feel like a minefield. Is bacon really a risk factor of cancer? Will coffee or eggs give you a heart attack? Does wheat contribute to Alzheimer’s disease? Will dairy products clog up your arteries? Worse still, the advice changes continually. As TV-cook Nigella Lawson recently put it: “You can guarantee that what people think will be good for you this year, they won’t next year.”
This may be somewhat inevitable: evidence-based health advice should be constantly updated as new studies explore the nuances of what we eat and the effects the meals have on our bodies. But when the media (and ill-informed health gurus) exaggerate the results of a study without providing the context, it can lead to unnecessary fears that may, ironically, push you towards less healthy choices.
The good news is that “next year” you may be pleased to learn that many of your favourite foods are not the ticking time bomb you have been led to believe...

What does the word nationalist mean? (Part I)

The dictionary's definition of the word seems innocent enough: a person devoted to nationalism (the devotion and loyalty to one's own country). But make no mistake about it. Nationalist is a loaded and controversial term.

It dates back to the 17th century and rose into prominence during the uprisings in the 18th century that produced the American and French revolutions. But the word attained more of a negative connotation during the 20th century as it become associated with the nationalism movements in Europe that helped lead to World War I and World War II. Today the word is often associated with the far-right, racist ideologies of white nationalists.

Nationalism has been on the rise worldwide, as evidenced by the success of nationalist political parties in Europe. And it had a double bang in 2016, as it powered Brexit in the UK and the election of Trump as US President. Steve Bannon, Trump's former top strategist, said Trump used an "economic nationalist agenda" to win.

Development of world's first autonomous, zeroemission feeder postponed amid COVID-19 crisis

Due to the COVID-19 pandemic and the changed global outlook, the development of the world's first autonomous and electric container vessel Yara Birkeland is put on hold, Norwegian company Yara announced.

Yara has decided to pause further development of the vessel and will assess next steps together with its partners, the company stated. The hull of the Yara Birkeland vessel was launched to sea in Romania in February 2020. The ship is expected to arrive at the Norwegian shipyard in May where it will be fitted with various control and navigation systems and undergo testing before delivery to Yara.
Yara and technology company Kongsberg teamed up in 2017 with the ambition to build the world's first autonomous and zero-emission container vessel.

Replacing 40,000 truck journeys a year, Yara Birkeland seeks to reduce NOx and CO2 emissions and improve road safety in a densely populated urban area in Norway.

Notre-Dame came far closer to collapsing than people knew

The security employee monitoring the smoke alarm panel at Notre-Dame cathedral was just three days on the job when the red warning light flashed on the evening of April 15: “Feu.” Fire. It was 6:18 on a Monday, the week before Easter. The Rev. Jean-Pierre Caveau was celebrating Mass before hundreds of worshipers and visitors, and the employee radioed a church guard who was standing just a few feet from the altar, and told him to go check for fire. He did and found nothing.

It took nearly 30 minutes before they realized their mistake: The guard had gone to the wrong building. The fire was in the attic of the cathedral, the famed latticework of ancient timbers known as “the forest.” The guard went to the attic of a small adjacent building, the sacristy.

Instead of calling the fire department, the security employee called his boss but didn’t reach him. The manager called back and eventually deciphered the mistake. He called the guard and told him to leave the sacristy and run to the main attic. But by the time the guard climbed 300 narrow steps to the attic, the fire was burning out of control, putting firefighters in a near impossible position. Ultimately, Notre-Dame still stands only because the firefighters decided to risk everything.

The miscommunication, uncovered in interviews with church officials and managers of the fire security company, has set off a bitter round of finger-pointing over who was responsible for allowing the fire to rage unchecked for so long. Who is to blame and how the fire started have not yet been determined and are at the heart of an investigation by the French authorities that will continue for months.

But the damage is done. What happened that night changed Paris. The cathedral — a soaring medieval structure that has captured the hearts of believer and nonbeliever alike for 850 years — was ravaged.

Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the passageway from the lower neck to the armpit. There are three main types: neurogenic, venous, and arterial. The neurogenic type is the most common and presents with pain, weakness, and occasionally loss of muscle at the base of the thumb. The venous type results in swelling, pain, and possibly a bluish coloration of the arm. The arterial type results in pain, coldness, and paleness of the arm

TOS may result from trauma, repetitive arm movements, tumors, pregnancy, or anatomical variations such as a cervical rib. Initial treatment for the neurogenic type is with exercises to strengthen the chest muscles and improve posture. NSAIDs such as naproxen may be used for pain. Surgery is typically done for the arterial and venous types and for the neurogenic type if it does not improve with other treatments. Blood thinners may be used to treat or prevent blood clots. The condition affects about 1% of the population. It is more common in women than men and it occurs most commonly between 20 and 50 years of age.

Uncontacted Amazon tribe has been threatened by illegal loggers

Remarkable close-up footage that appears to show an uncontacted tribesman in the Amazon rainforest has been released by an indigenous media group that wants to raise awareness of the threat posed by illegal loggers, miners and drug traffickers.

(...) The Awá have been described as the world’s most threatened tribe by the NGO Survival International, which has tracked killings by loggers, who surround and frequently encroach upon the group’s territory.

Many of the community have been forced to abandon the forest, but some remain in self-imposed isolation. Their existence has been called into question by commercial interests that want to move into the land, but the new footage has been cited as proof that they remain in the territory.

It was recorded by a member of a neighbouring tribe, the Guajajara, which is trying to defend one of the last pockets of intact forest in Maranhão, a massively deforested state in the north-east of Brazil.

''We hope this film produces something positive. We hope it makes an impact around the world to help protect our people and our forest,'' said Flay Guajajara, who shot the image while out hunting and released it through the Mídia Índia platform.

(...) Olimpio Guajajara, coordinator of the Guardians of the Amazon, said three of the group’s members have been murdered in this activity, which highlighted the need for more long-term support. He said: ''We Guardians are defending our people’s rights, defending the uncontacted Indians, and defending nature for all of us. We need the land to be protected for good."

Indigenous groups say successive governments have failed to adequately recognise their territorial rights and their role in protecting forests that are globally essential for carbon sequestration and natural habitats.

According to Survival International, loggers have been emboldened by the government and their camps can now be seen on the edge of Awá land.

Director Stephen Corry said: ''This video is further proof that the uncontacted Awá people really exist. And a glance at a satellite photo shows just how much danger they’re in. Loggers have already killed many of their relatives and forced others out of the forest"
