After the strategic victory of the Ukrainian army in Lyman in the Donetsk region, the entire area must be secured so that the residents can lead normal lives again.

Now that Lyman has been released, it’s time to clear mines. One of the first teams arrived at the entrance of the Ukrainian city on Tuesday, October 4th. Your mission is extremely dangerous but essential to resume life. Vehicles abandoned after battles may be loaded with explosives. “We are concentrating on the roads and the forest. We are also putting up signs pointing out mined areas,” said one man.

Deminers spend every square inch with a metal detector. They found grenades, several mines and the body of a Russian soldier. The few inhabitants of the city are at the end of their strength, many are starving. “I’ve worked 46 years, I never thought I’d have to ask for food, I’m reduced to it,” laments a woman. Despite the victory, the Ukrainian army is still very active in the Lyman area, as Russian soldiers are said to be hiding in the forests.

The three wounded youths, one of whom was shot in the head, were rescued and taken to the Santa Casa hospital in Sobral, a municipality in Ceará state, a spokesman for Ceará’s security secretariat told Efe.

The 15-year-old teenager suspected of attempted murder has been arrestedaccording to a statement released by the same agency.

According to the source, the young man was carrying a firearm registered in someone else’s name, registered with a hunter-shooter-gatherer permit.

The worst tragedy to happen in a Brazilian school happened in 2011 when twelve students at a school in Realengo, a modest neighborhood on the outskirts of Rio de Janeiro, were shot and killed by a 24-year-old man who committed suicide while he was there was intercepted by the police. .

Amid military setbacks in Ukraine, Russian President Vladimir Putin has promoted Chechnya’s authoritarian ruler Ramzan Kadyrov to colonel general. His appointment decree has now been published and he is “incredibly grateful” to Putin for his “great appreciation,” Kadyrov wrote on the Telegram online service on Wednesday. The Colonel General is the third highest rank in the Russian Armed Forces, behind the Marshal and the General of the Army.

On Monday, the Kremlin praised Kadyrov’s “heroic contribution” to the Ukraine offensive. The Chechen president was intensely involved from the start. Chechen units are fighting alongside Russian forces in the country. Among them is Kadyrov’s notorious personal militia known as “Kadyrovtsy”.

Kadyrov announced on Monday that he would send three teenage sons to fight in Ukraine. The 14-16 year olds Achmat, Selimkhan and Adam are ready to use the combat skills they trained in “special military operation”, Kadyrov wrote on Telegram on Monday. “And I’m not kidding. (…) Soon they will be sent to the front and will be in the most difficult parts of the contact line.” He also posted a video showing his kids at target shooting.

brutal management style

Kadyrov, known for his brutal leadership in Muslim-leaning Chechnya in the North Caucasus, has emerged as one of the most ardent advocates of war since Russia’s invasion of Ukraine. He also has a reputation for breaking Russian laws without consequences. After the Russian defeats, he repeatedly criticized his country’s military leadership and called for far-reaching consequences. Recently, he even spoke out in favor of considering the use of lower-yield nuclear weapons. In addition, Kadyrov had criticized another colonel general, Alexander Lapin, for his role in the fight for the city of Lyman, recently captured by Ukrainian forces.

When asked about Kadyrov’s harsh criticism of the course of the war, which Moscow continues to call a “special military operation”, Kremlin spokesman Dmitry Peskov said only on Monday: “Regional chiefs have the authority to express your point of view and to make evaluations.” At first he didn’t comment on the soldiers.

The Chechen ruler has been criticized for years by international non-governmental organizations because of his administration, which is characterized by serious human rights violations.

Prior to his current appointment as colonel-general, Kadyrov had already been promoted to general three times – each of the interior armed forces, the police and the Chechen national guard.

This year’s Nobel Prize in Physics went to researchers in the field of quantum mechanics the science that describes the behavior of subatomic particles, i.e. physics at the smallest possible scales.

The prize goes to the Frenchman Alain Aspect, the American John Clauser and the Austrian Anton Zeilinger. The researchers will share the prize money of 10 million Swedish kroner (4.7 million R$).

The work of these scientists could pave the way for a new generation of powerful computers and telecommunications systems that are unhackable.

This year’s three laureates have performed groundbreaking experiments involving entangled quantum states, in which two subatomic particles behave as one, even when separated.

“Quantum information science is a vibrant and rapidly evolving field,” said Eva Olsson, a member of the Nobel Committee on Physics. “It has farreaching and potential implications in areas such as secure information transmission, quantum computing and detection technology.”

Alain Aspect, 75, is a member of the Université ParisSaclay and the École Polytechnique, Palaiseau. John Clauser, 79, runs his own company in California. Anton Zeilinger, 77, is affiliated with the University of Vienna. The same three men won the Wolf Prize together in 2010.

Anton Zeilinger got a call early in the morning to say he had won. “I’m still a bit shocked, but it’s a very positive surprise,” he said.

entanglement

Quantum mechanics describes the behavior of subatomic particles. It is an area of ​​research that began in the early 20th century.

One of the areas of quantum mechanics is “entanglement,” where two or more quantum particles usually photons, the particles of light can remain tightly coupled if they are very far apart and not physically connected.

Your common state can be your energy or your spin. It’s a strange phenomenon that Albert Einstein called “spooky action at a distance.”

The theoretical basis was developed in the 1960s by the Northern Irish physicist John Stewart Bell. But it was Aspect, Clauser and Zeilinger who ran the experiments to show that the phenomenon was real and could have practical applications.

“I’ve always been interested in quantum mechanics since I first read about it,” Zeilinger told BBC News. “And I was really impressed with some of the theoretical predictions because they didn’t fit the usual intuitions that you might have.”

Two practical applications for entanglement research have recently received much attention. One of them is quantum computing, which promises a giant leap in the ability of machines to solve complex problems. And the other lies in encryption, the secure encryption of information. Exploiting quantum entanglement will make it impossible for third parties to eavesdrop on private communications.

“This is useful for the military and banks etc. when communicating securely,” said John Clauser. “The biggest application I know of comes from the Chinese, who launched a satellite a few years ago, which they use for secure communications over thousands of kilometers.”

Professor Tim Spiller, from the University of York, UK, said Tuesday’s award winners were worthy winners who helped open up possibilities for an exciting future.

“Quantum technologies have been explored significantly in the UK and many other countries over the last 10 years. We’ve known about entanglement for a lot longer, but the investment was made in the last 10 years. And now there are one or two commercial products, new technologies that you can buy that take advantage of different aspects of this quantum resource, and we hope there will be many more in the future,” he told BBC News.

The 2021 Nobel Prize in Physics was awarded to three researchers who have advanced our understanding of complex systems particularly the Earth’s climate.

On Monday, the Nobel Committee awarded the Prize in Physiology or Medicine to Svante Paabo of Sweden for his work on human evolution.
