One of the pioneers of the US oil shale industry declared bankruptcy :: Business :: RBC

Chesapeake Energy shale oil producer owes $ 7 billion. Bloomberg said earlier that control of the company could go to one of the lenders.

Chesapeake Energy, considered one of the pioneers in the US oil shale industry, has filed for bankruptcy, according to the corporation’s website.

“The company has voluntarily filed for Chapter 11 defense with the United States Southern Texas Bankruptcy Court to facilitate a comprehensive restructuring of the balance sheet,” the statement said.

The company’s debt amounted to about $ 7 billion. Under an agreement with creditors, Chesapeake Energy will receive a loan of $ 925 million. In addition, lenders and holders of secured bills will allocate $ 600 million to it.

The flagship of the US oil shale industry pledged almost all assets on a loan

According to the corporation’s report, in the first quarter of 2020, Chesapeake Energy’s net loss was $ 8.3 billion, and its liquidity was $ 82 million.

Mississippi announces possible flag change due to protests :: Society :: RBC

Mississippi Governor Tate Reeves said he was ready to change the state flag amid protests against racism in the United States. He wrote about this on Twitter.

“For several days, lawmakers cannot break the deadlock when discussing the new flag. The discussion on the 1894 flag is as controversial as the flag itself. It’s time to put an end to her. I’m ready to sign the bill if they send it to me on the weekend, ”Reeves wrote.

The Mississippi flag is the only state flag in the United States to display Confederate symbols – a blue cross with stars. The Confederate States (Southerners-slave owners) were opponents of the northerners in the Civil War of 1861-1865, one of the reasons for which was the policy of the non-proliferation of slavery in the country.

Travelers and Confederates: whose monuments are demolished in the USA and Europe

The governor made such a statement amid ongoing protests in the United States caused by the death of African American George Floyd in Minneapolis on May 25. The man died in the hospital after being detained by a policeman who, for almost nine minutes, used a choke to him.

I did not have time to get out, but it is already buggy! TOP 3 “bugs” in KIA Seltos

Motorists who own a Korean crossover talked about its glitches.

KIA Seltos – A novelty of the Russian car market, which is available at a price of 1,074,900 rubles. Of course, for such an amount the car has found many fans and diverges like hot cakes. However, experience shows that in a Korean car, not everything is so rosy.

Motorists called TOP 3 “bugs” in KIA Seltosdue to which the crossover is buggy. So in first of all it is worth noting a glitch on-board computer when refueling. One of the motorists said that when his KIA Seltos had almost no gas left in the tank, he refueled 300-400 rubles, but the range on the scoreboard did not increase – the arrow rose, but not much.

After restarting the car, nothing has changed. After he refueled Seltos by another 200 rubles, voila – the mileage increased. The owner of the “Korean” came to the conclusion that if the tank is on zero, you need to refuel it by at least 500 rubles, so that the range on the scoreboard increases.

The second “bug” KIA Seltos is connected to the multimedia system. So, if you call one subscriber, the number of the user whom the driver called before is displayed on the monitor.

The third glitch of the Korean crossover is that the music does not turn on after resetting the conversation, and the monitor shows that the conversation is still ongoing. This problem is solved by restarting the machine, but everyone will agree that this is quite inconvenient.

How to call with a hidden number from iPhone and Android phones

Madrid

Updated:

save

It is possible that, on some occasion, you had to make a call but you were not very happy to share your number with the recipient. Whether for work issues or for some other reason. Be that as it may, you should know that your mobile phone, regardless of whether it has an operating system iOS or Android, you have the option to make calls in stealth, so that the other person cannot see who is trying to contact you. Instead, you will see a phrase like «Hidden call», «appear on your mobile screenHidden number»,« Unknown »or similar.

There are two ways through which this can be achieved. The first is for a single call and the second can be permanent, as long as the user wishes. If you want to make a hidden call in particular, the only thing to do is put the prefix # 31 # before the contact’s phone number. This functionality is similar on both iOS and Android devices. However, in case the user has decided that he wants to make all the calls keeping his number secret, the route to be followed changes depending on the operating system.

On iOS

In case you want activate this function permanently in its iPhone, you must go to «Settings». Once inside you will have to go to the “Telephone” section, where you will find the “Show caller ID” option. For all the calls you make to be hidden, you just have to slide your finger on the screen and deactivate it. Note that this change is reversible, so if you ever want to stop appearing as “Unknown”, you just have to go through this route again and activate the Caller ID.

On Android

In Android it is more or less the same. You have to access “Settings” and then consult “Advanced Features” or similar where the option “Show my caller ID” is collected. Depending on the version of the operating system that is installed, three options will appear: «Default values», «Hide number», «Show number».

Note that on Android the route may change depending on the deviceSo if you cannot find these options on your terminal, the easiest thing for the user to do is to contact their operator and ask them to hide the phone from them in future calls. This process can be reversed smoothly in the future by making another call to cancel it.

United States: Trump presents a peace plan that supports Israel’s key interests | U.S

The President of the United States, Donald Trump, presented this Tuesday at the White House the call century deal for the Middle East, a grandiose name for a peace plan that was born mortally wounded, despite the almost three years it has been in the pipeline. The proposal gives Israel much of its historic aspirations, while offering the Palestinian authorities a road map to its own state subject to so many constraints that make it unlikely. That Trump expounded the plan accompanied by only one of the parties, the exultant Israeli Prime Minister, Benjamin Netanyahu, gave a good account of the chicken flight of the project.

“Today Israel is taking a big step towards peace,” Trump has said from the East room of the White House. This is, he said, “an opportunity for both sides to win, a realistic two-state solution that solves the Palestinian state’s risk to Israel’s security,” he stressed.

The plan forged by Washington more than doubles the territory under Palestinian control, according to the White House, although this expansion is impossible to identify on the maps that the specific document projects on that future state. Under the title of The Vision (The Vision), that future Palestinian state would comprise the West Bank and the Gaza Strip, which would be connected by tunnels or elevated roads and leaves the valued Jordan Valley under Israeli military control.

Trump presents a peace plan that supports Israel's key interests



The proposal freezes for four years the construction of new settlements in order to make possible the solution of the “two states”, but calls on the Palestinian authorities to recognize Jerusalem as Israel’s sole capital, ruling out the dismantling of existing settlements and establishes the consideration of Israel as a Jewish State, three points that complicate the approval of the Palestinian president, Mahmud Abbas.

The proposal includes a rain of 50,000 million dollars (45,420 million euros) in investments over 10 years to promote prosperity, but that does not quite convince the Palestinian authorities. Half would go in principle to Gaza and the West Bank and to neighboring countries such as Jordan and Egypt.

“President Abbas, if you accept this path to peace, the United States and many other countries will be there to help you,” the US president has appealed, admitting that his Administration had been very favorable to Israel and assuring that he now wanted it to be “very good for the Palestinians too.”

Jerusalem, where cultures and beliefs intermingle, is the heart of the conflict in the Holy Land. In the original partition plan of Palestine under British mandate approved by the UN in 1947, an international status was reserved for it, regardless of the planned Jewish and Arab States. But it was divided by force of arms in 1949, with the eastern sector under Jordanian control, and entirely occupied by Israel in the Six Day War in June 1967. A third of its 900,000 inhabitants are Palestinians, with the right of residence but without nationality in his hometown. The Agreement of the century It appears to point to a return to the Palestinian Authority of several eastern and northern districts totaling some 100,000 residents, effectively separated in fact for 15 years by the separation wall erected by the Army after the explosion of violence from the Second Intifada.

Palestinians have always called for a return to the 1967 borders, which would involve establishing the capital of their future state in East Jerusalem, which includes the walled compound of the Old City with the holy sites of Christianity, Judaism, and Islam. In all previous peace plans, mediators preferred to postpone the final status of the Holy City until a final agreement was reached between Israelis and Palestinians. Trump ended the international consensus in 2017 with a statement recognizing Jerusalem as the capital of Israel. Since then all bridges between the White House and the Palestinian Authority have been broken and on Tuesday the American put a new nail in the coffin.

But the Republican seeks, with the presentation of such an ambitious plan, which tries to end 70 years of conflict, a sort of culmination to his latest movements in foreign policy. Over the course of weeks, he has succeeded in getting Congress to approve the reformulation of the trade agreement with Mexico and Canada, has signed a principle of agreement with China to leave the trade war behind, and has killed a powerful Iranian general accused by Washington of collaboration with terrorism, Qasem Soleimani, without the operation having led, at least today, to a war escalation. Everything, at a more than complicated moment in national politics, in full impeachment by the scandal of pressure on Ukraine.

Netanyahu also helps, as he is accused in three corruption cases, in addition to the election he faces next month. This Tuesday, Israel’s attorney general has requested the prime minister’s prosecution for corruption. In Trump’s Washington, he has found a firm ally, starting with the fact that the person to whom the Republican has entrusted this thorny case is none other than Jared Kushner, son-in-law of the president and personal friend of Netanyahu.

This, as if intervening in an electoral rally, promised that the absorption of the strategic Jordan Valley and the settlements would affect 40% of the West Bank, in a cut that threatens the viability, due to lack of territorial continuity, of the future Palestinian State. This will be the case of the area known as E-1, between Maale Adumin and Jerusalem, whose annexation will practically divide the West Bank between north and south, like the Bantustans of South Africa in the apartheid. “This will give us a permanent eastern border to defend ourselves,” Netanyahu said.

The “realistic” two-state solution, but with less than one state, offered by Trump to the Palestinians in a letter sent to President Mahmud Abbas, is justified only by a huge injection of international funds in Gaza and the West Bank, but not guarantees a lasting political settlement to a conflict over 70 years old.

For the millions of Palestinian refugees, of whom at least five million are protected by a UN agency to subsist, the Israeli Prime Minister has only stated that his problem “must be solved outside the State of Israel”, thus excluding any perspective of the right of return to the houses and lands that they owned in 1948. Their destiny seems to remain, as until now, in the hands of the international community, neighboring countries and the economic compensation they may receive in exchange for renouncing their past. .

Yvonne Choquet-Bruhat: Mathematical physics that proved that the future of the universe is well defined | Science

The Spanish philosopher José Ortega y Gasset affirmed: “To be surprised, to be surprised … is to begin to understand.” The same idea pushed from girl to Yvonne Choquet-Bruhat to want to “unravel some of the secrets of the strange universe in which we live, and the role that human beings play in it,” as expressed in their autobiography. The French scientist, who turned 96 on December 29, has always hoped that physics and mathematics could help us carry out this effort. His contributions, fundamentally framed in the field of general relativity, have made him a leading figure in the area of ​​mathematical physics of the twentieth century.

Yvonne Choquet-Bruhat – the last name “Choquet” acquired it in his second marriage to Gustave Choquet – was born in Lille (France) in a cultured family. His father, Georges Bruhat (1887-1945), was a professor of physics at the University of Lillle, and his mother, Berthe Hubert (1892-1972), professor of art, literature and philosophy in several French high schools. From an early age, Choquet-Bruhat showed great talent for physics and mathematics. At eighteen he won a silver medal of the “General Concours”, a nationwide competition in which the best students in the country were rewarded. In 1943 he began his Mathematics studies at the Superior Normal School of Sévres, on the outskirts of Paris, where he graduated three years later.

It was then that he began his research activity at the prestigious French National Center for Scientific Research (CNRS), under the advice of the renowned mathematical physicist André Lichnerowicz. He completed his thesis on the so-called initial value problem (or Cauchy problem) in the context of general relativity, in which the existence of solutions for the equations proposed by Albert Einstein is studied, when they meet certain starting conditions. In the cosmological framework, the question would determine whether the future of the universe is well defined when we only have its information in a “specific time”, which is known as the initial data of the problem.

Choquet-Bruhat managed to prove, by studying complex differential equations and geometric techniques, that if it is based on an initial fact that meets certain plausible physical restrictions, there is only one possible future for the universe

Choquet-Bruhat managed to prove, by studying complex differential equations and geometric techniques, that if it is based on an initial fact that meets certain plausible physical restrictions, there is only one possible future for the universe. His doctoral work, entitled “Théorème d’existence pour certains systèmes d’equations aux dérivées partielles non linéaires”, highlights the deterministic nature of Einstein’s theory, since the future of the universe is fixed by the information that Describe in an instant of time.

In 1949 Choquet-Bruhat was appointed assistant investigator of the CNRS, and later associate. In 1951 he accepted a postdoctoral contract at the Institute of Advanced Studies in Princeton in the USA There he had the opportunity to meet Einstein, who could explain in his office, with a combination of French and English, the main achievements of his thesis. The German genius congratulated her on the work done and invited her to visit his office whenever he wanted.

The solution to the Cauchy problem has based, among other research fields, the study of the stability of the solutions of the Einstein equations, which analyzes how much the universes that arise from slight disturbances of the initial data vary. Do you get a slightly different universe than expected, or would it have almost nothing to do with it? On the other hand, this work facilitated the use of numerical and analytical techniques to approximate the solutions of Einstein’s equations, since they are usually very difficult to calculate explicitly. Apart from its importance in the theory of general relativity, the work of Choquet Bruhat has established the basis for the study of other physical theories such as relativistic hydrodynamics, non-Abelian Gauge theory or supergravity.

Among other merits, it is worth noting that she was the first woman chosen to be part of the French Academy of Sciences

The fruitful scientific trajectory of mathematical physics has resulted in a total of seven books and three hundred articles, which have made it worthy of important national and international awards and prizes. Among other merits, it is worth noting that she was the first woman chosen to be part of the French Academy of Sciences, on May 14, 1979.

In the last lines of her autobiography, the French scientist recalls a reflection of the philosopher Blaise Pascal, in which he admits to having “a tremendous ignorance of everything”. Although Choquet-Bruhat recognizes the huge amount of questions that remain to be answered, their contributions have meant considerable scientific progress.

After a life dedicated to research, Yvonne Choquet-Bruhat has been able to see her childhood dream come true: to shed light on some of the mysteries of the universe in which we live.

Alberto Soria He is a postdoctoral researcher at the Institute of Mathematical Sciences (ICMAT) and is a professor at the Catholic University of Ávila

Coffee and theorems It is a section dedicated to mathematics and the environment in which they are created, coordinated by the Institute of Mathematical Sciences (ICMAT), in which researchers and members of the center describe the latest advances in this discipline, share meeting points between mathematics and other social and cultural expressions and remember those who marked their development and knew how to transform coffee into theorems. The name evokes the definition of the Hungarian mathematician Alfred Rényi: “A mathematician is a machine that transforms coffee into theorems.”
