Defenders of Roosevelt Statue Converge on Natural History Museum

Defenders of Roosevelt Statue Converge on Natural History MuseumNEW YORK -- For more than a dozen years, Marion Reid, 77, had walked past the statue of Theodore Roosevelt on his way to work in information technology at the American Museum of Natural History, an employer that he said often failed to treat African Americans with dignity.He drove into Manhattan around noon on Sunday to photograph the statue before officials carried out plans to remove it from its place of pride at the museum's Central Park West entrance, only to find himself engulfed by about 150 protesters clamoring to preserve it. Among them were men in seersucker suits and women draped with pearls, people wearing MAGA hats and others waving Blue Lives Matter flags while chanting, "Save Teddy. Save our police. Save law and order." About a dozen police were in the vicinity.The protesters Sunday came to defy the nationwide movement that for decades has fought to bring down monuments that, like the Roosevelt statue, have been associated with racism, colonialism and oppression."We are fighting over the last will and testament of the United States," David Marcus, an organizer of the rally and a contributor to conservative website The Federalist said through a megaphone. "We are full-blooded brothers and sisters, and heirs to the most extraordinary experiment in freedom that the world has ever known. God bless Teddy Roosevelt."The museum announced last week that, with approval from the mayor and Roosevelt's family, it would remove the 80-year-old bronze statue.The museum's president, Ellen V. Futter, emphasized last week that the decision was not about Roosevelt but about the statue itself -- namely its "hierarchical composition." It features the president riding high on horseback, flanked by a Native American man and an African man, depicting them, Mayor Bill de Blasio said, "as subjugated and racially inferior."Speakers supporting the statue used the protest to rail against a broad range of issues including abortion and religion. One woman called for the removal of "the feminists and the homosexuals" from the City Council.A protester in her 70s who gave her name as Sharon, said, "I don't see the statue as racist, and that word is overused and dramatized today." She said the debate over the statue, "certainly has nothing to do with that police situation in Minneapolis where a man was murdered." She was referring to George Floyd, who died in police custody on May 25."Over the last few weeks, our museum community has been profoundly moved by the ever-widening movement for racial justice that has emerged after the killing of George Floyd," Futter said in an interview. "We have watched as the attention of the world and the country has increasingly turned to statues as powerful and hurtful symbols of systemic racism."The decision came as a pleasant surprise for the hundreds of activists who have demanded the monument's removal through annual Columbus Day protests at the museum, which saw the statue splashed with red liquid in 2017.Most protesters in the crowd were not wearing masks despite the global surge in COVID-19 cases.Worries about the coronavirus pandemic had failed to dissuade Gavin Wax, 26, from planning the protest. "This is about much more than a statue," Wax, the president of the New York Young Republicans Club said. "You can't judge premodern people by postmodern standards of morality, because at that rate you won't have a history."Wax said, "We have to calm down and say that nobody sees racism in this statue. If you do, you have to look into yourself and not other people."For Reid of Westchester, the former museum employee, who is Black, the problem is a simple one. "The statue is racist," he said. "What I see here are Trumpites who want a return to the status quo. They want 'Gone With the Wind,' the good old days when African Americans were kept in their place and racism was swept under the rug."This article originally appeared in The New York Times.(C) 2020 The New York Times Company

Russia's mining giant admits to dumping contaminated water into Arctic tundra

Russia's mining giant admits to dumping contaminated water into Arctic tundraRussia's mining giant Norilsk Nickel has admitted to spilling wastewater into the wild less than a month after it caused a disastrous oil spill in the same region. Environmentalists and journalists in the Arctic city of Norilsk on Sunday caught an enrichment plant owned by Norilsk Nickel dumping water full of heavy metals into the Arctic tundra. The Novaya Gazeta newspaper published footage from outside the city of Norilsk, showing metal pipes leading from a reservoir and releasing foaming liquid into the nearby woods. The journalists called the police to the scene, prompting the workers to begin to dismantle the pipes. Environmental activists who took samples at the site of the spill were stopped at the local airport over the weekend and barred from shipping them to Moscow for tests. An official quoted by the Tass news agency on Monday said that up to 6,000 cubic metres of "unknown liquid with a chemical odour" is believed to have been pumped into tundra. London-traded Norilsk Nickel later on Sunday admitted to the incident, saying that it has suspended the workers who decided to pump the water into the tundra. Unnamed workers at the Talnakh plant reportedly suspected that the reservoir for the liquid used to process minerals would soon get overflow and decided to dump the wastewater into the nearby tundra. Investigators are looking into the incident. Norilsk Nickel, with the market capitalisation of £36 billion, is a major taxpayer in the region, employing more than 73,000 people. The metal company's environmental record came into question last month when some 20,000 metric tonnes of diesel fuel spilled into the river system from a tank at a power plant it owns. The fuel spill, which has been blamed on thawing permafrost, has been described as the Arctic's worst since the 1989 accident off the coast of Alaska. Vladimir Chuprov, project director at Greenpeace Russia, says that the Arctic spill has shed the light on the magnitude of day-to-day pollution in Norilsk by one of the country's biggest industrial companies. "Norilsk Nickel has been dumping waste water, which is proved by satellite images," he said, adding that it is high time that the company "stops hiding the violations and gets down to rectifying them." Norilsk Nickel insists that it responds to all reports about potential environmental damage.


Равнополочный алюминиевый уголокУголок равнополочный является сегодня довольно популярным материалом. С ним взаимодействуют во многих отраслях. Это обусловлено отменными эксплуатационными данными изделий: он прочный и в то же время легкий. Поэтому их все чаще можно увидеть там, где невозможно применение его аналога из стали.

Помимо перечисленных характеристик, равнополочные уголки отличаются долговечностью, переносимостью воздействия как высоких, так и низких температур. Алюминиевый равнополочный уголок обладает высокой устойчивостью к коррозии, ультрафиолетовых лучей, химических жидкостей, кислот и влаги. При взаимодействии с воздухом на его поверхности возникает окисная пленка, которая играет роль барьера и увеличивает период его эксплуатации.

Также на уголки равнополочные может быть нанесено покрытие одним из методов:

  • распыление полимерной порошковой краски;
  • декорирование и ламинирование;
  • анодирование (путем создания на поверхности алюминия оксидного слоя).

Разные составы цветовых решений позволяют вписать их в производственный цикл для производства шкафов-купе, гардеробных комнат и прочей домашней мебели. Вышеприведенные нюансы помогут оценить их особенности, анодированные равнополочные уголки пользуются популярностью у многих потребителей - организаций и частных лиц.

Еще одно достоинство заключается в том, что они без каких либо проблем поддаются практически любой механической обработке. Его можно сверлить, шлифовать и придавать ему разлиную форму. Для их скрепления используются саморезы.

Как делаются уголки равнополочные

Производство их, как правило, осуществляется экструзией или гибкой. В зависимости от технологии выделяют вот два типа:

  • прессованные;
  • гнутые.

При этом они могут поступать в продажу в исходном состоянии или подвергнутые одному из нескольких способов термообработки. Экструдируют их на мощных гидравлических прессах через формообразующий элемент - фильеру, или так называемую матрицу. Гнут на гибочных станках. Стоить отметить, что им свойственно иметь более десятков тысяч размеров. Наиболее маленьким считается размер 10х10х1 мм, его противоположность, габарит 200 мм шириной и 200 мм высотой.

И так, подведем итоги: сплошной профиль, гораздо надежнее поливинилхлорида и дерева, так как не боится температурных скачков, алюминию не страшны жара и морозы, он устойчив к негативным атмосферным проявлениям. Они, профили, не воспламеняются и не поддерживают процесс горения, не продуцируют токсинов даже в случае нагревании, что дает возможность использовать их в жилых помещениях. Они не выделяет в атмосферу ядовитых веществ, абсолютно безвредны для человека. И монтировать их - одно удовольствие, скажем так, достаточно просто. Кроме того, они просты в обслуживании. И самое главное, они отличаются доступной ценой.

'Like two guys in a steam bath': Trump consistently sought approval from Putin during calls and was 'outplayed' by Russian leaderPrivate calls between Donald Trump and Vladimir Putin have the tone of "two guys in a steam bath" according to an aide's account of the conversations described to CNN. The US president is often ousmarted by his Russian counterart, according to the aide's summary. It comes amid concerns that the Trump administration did not act on reports that Russia planned on paying Taliban bounties to kill American soldiers in Afghanistan. Mr Trump dismissed those claims as "another fabricated Russia Hoax, maybe by the Fake News".Russian authorities added that president Putin had not discussed the claims with president Trump, and denied the Taliban plan.
