New Numbers Showing Coronavirus Spread Intrude on a White House in Denial
WASHINGTON -- In the past week, President Donald Trump hosted an indoor campaign rally for thousands of cheering, unmasked supporters even as a deadly virus spread throughout the country. He began easing up on restrictions that had been in place at the White House since Washington instituted a stay-at-home order in response to the coronavirus in March, and he invited the president of Poland to a day of meetings. Then, Thursday, he flew to Wisconsin to brag about an economic recovery that he said was just around the corner.But by Friday, it was impossible to fully ignore the fact that the pandemic the White House has for weeks insisted was winding down has done just the opposite.The rising numbers in Texas, Florida and Arizona made that clear, as well as the reality that those are all states where the president and his Republican allies had urged people to return to normal.In a reflection of a growing sense of anxiety over the new numbers, Vice President Mike Pence and members of the coronavirus task force held a public briefing for the first time in two months. But ever loyal to Trump's desire for good news, Pence tried to tiptoe around the statistics that Dr. Deborah L. Birx, the task force coordinator, pointed to, showing surging cases and hospitalizations in Florida, Texas, Arizona and other states."We have made a truly remarkable progress in moving our nation forward," the vice president said. "We've all seen the encouraging news as we open up," he added, dismissing any suggestion that the outbreaks across the South should prompt a return to the shutdowns that Trump so badly wants to be over. "The reality is we're in a much better place."Refusing to wear a mask even as the health officials next to him did, Pence described the recent outbreaks across the country as little more than the product of increased testing among younger, more healthy Americans who should be less likely to get seriously ill from the coronavirus even as they spread it to others."Very encouraging news," he said.But Pence's comments came against the backdrop of a very different message from Birx and Dr. Anthony S. Fauci, the nation's top infectious disease expert, who warned of a broken testing system and said the outbreaks could engulf the country."If we don't extinguish the outbreak, sooner or later, even ones that are doing well are going to be vulnerable to the spread," he warned. "So we need to take that into account because we are all in it together. And the only way we're going to end it is by ending it together."The return of the televised task force news conference -- at which reporters were limited to only a handful of questions -- revived the deep disconnect between Washington and the states where local officials spent Friday sounding the alarm and, in some cases, halting the reopening that Trump has so often encouraged.In Florida, Gov. Ron DeSantis, a Republican who has resisted rolling back the economic reopening, banned drinking in bars after saying that patrons were not abiding by social distancing rules. In Texas, Gov. Greg Abbott, also a Republican, went further, ordering all bars closed in the state. And Judge Lina Hidalgo of Harris County, the largest county in Texas, reimposed stay-at-home orders Friday, calling the rise in cases there "a catastrophic and unsustainable situation."Taken together, it was grim news about a pandemic that is still a threat to the public's health, the nation's economy and the president's political future.At a time when his poll numbers now call into question whether he can win a second term in November, Trump faces the prospect that his efforts to boost the economy by shrugging off the virus have backfired. Rather than head into the summer with a country on the mend, the president will be forced to explain how his response to the coronavirus contributed to a resurgence of it that may force some Americans back into a painful shutdown.And yet Trump made no appearance at the task force briefing to demonstrate concern. Instead, an hour after it was over, the president addressed a panel of industry officials, political allies and White House economic advisers for a self-congratulatory session about how successful the economic recovery has been.In taking his victory lap, Trump made no mention of the increase in cases around the country, underscoring a message that he posted on Twitter late Thursday night: "Our Economy is roaring back and will NOT be shut down. 'Embers' or flare ups will be put out, as necessary!"All spring, Trump expressed his impatience and annoyance with the social distancing measures that various states, and his own aides, were taking.He showed some concern when his personal valet, who serves his food, was diagnosed with the coronavirus and Pence's press secretary tested positive. But since then, Trump has maintained a posture of denial and dismissiveness.He has been enabled by a handful of advisers, some of whom share his desire to focus on the economy and some of whom are afraid of the president's reaction if they press him too hard about the public health crisis unfolding once again in large chunks of the country.The White House chief of staff, Mark Meadows, has been among the chief proponents of keeping the administration's public health experts largely out of sight, according to several senior administration officials.But he is not alone. Even though they are aware that Trump's mishandling of the virus presents a threat to his reelection, his campaign advisers agreed to his demand for the rally last Saturday at an arena in Tulsa, Oklahoma, hoping the adulation he would receive there would snap the president out of a funk he has been in for months.But at least eight staff members -- including two Secret Service agents -- tested positive for the virus before the rally, which was lightly attended and attracted none of the overflow crowd that Trump's advisers had promised. Since then, dozens of campaign aides who were in Oklahoma for the event have been told to quarantine.His advisers are now trying to figure out how to give Trump the traveling road show he wants while acknowledging the widespread fears about the coronavirus and allowing for proper health measures. At the same time, the White House has stopped employing the health checks it had been using for several weeks, like temperature checks for people entering the complex.One of the states where the cases are rising drastically is Florida, where Trump insisted the Republican National Convention at the end of August be relocated to meet his desire for a large-scale event free of social distancing measures. As of now, Republicans hope to put on a show celebrating Trump, the first lady and Pence with three nights of crowds as large as 12,000 people in Jacksonville.Some of the president's political allies have signaled in recent days that they intend to take the threat of the virus more seriously.Speaking to a group of health care workers in Morehead, Kentucky, Sen. Mitch McConnell, R-Ky., the majority leader, held up a simple face mask."Until we find a vaccine, these are really important," the senator said. "This is not as complicated as a ventilator. This is a way to indicate that you want to protect others. We all need during this period until we find a vaccine to think of us as protecting not only ourselves but others."And Rep. Liz Cheney, R-Wyo., had a not-so-subtle message for Pence in a tweet she posted not long after the vice president refused to wear a mask during the task force briefing Friday. Her tweet included a picture of her father, former Vice President Dick Cheney."Dick Cheney says WEAR A MASK," she wrote, adding the hashtag: realmenwearmasks.But if anything, Trump, Pence and the rest of the senior members of the administration have seemed determined in the past 24 hours to embrace a previrus political reality -- even if the medical facts contradict it.On Thursday night, the Trump administration asked the Supreme Court to overturn the Affordable Care Act, a move that, if successful, would bring a permanent end to the health insurance program popularly known as Obamacare and wipe out coverage for as many as 23 million Americans.In an 82-page brief, the administration joined Republican officials in Texas and 17 other states in arguing that in 2017, Congress, then controlled by Republicans, had rendered the law unconstitutional when it zeroed out the tax penalty for not buying insurance -- the so-called individual mandate.The president's argument is sure to reignite Washington's bitter political debate over access to affordable health care even as the accelerating pandemic has left millions of unemployed Americans without employer-provided health coverage.This article originally appeared in The New York Times.(C) 2020 The New York Times Company
Removing John Calhoun's Name Is Easier Than Erasing His Racist Legacy
By Christian K. Anderson, The ConversationWhen I toured the South Carolina Governor's Mansion in 2019, I noticed the multi-volume papers of John C. Calhoun on display. It struck me as remarkable that Calhoun's ideas would be featured so prominently given his vigorous defense of slavery and his role in laying the groundwork for the Civil War.But the reality is Calhoun's legacy until now has been quite prominent in American society—and not just in the South.His statue stands between the two chambers of the House and Senate in the South Carolina Statehouse. However, a separate statue in Charleston has been removed from the town square following nationwide protests sparked by the killing of George Floyd during an encounter with police. The statue had stood for 124 years just a block from Mother Emanuel Church, site of the horrific shooting massacre in 2015 of nine Black worshipers by an avowed white supremacist. The church is also located on Calhoun Street.Despite his historic prominence, Calhoun's days as a revered icon in the public sphere are gradually coming to an end. CALHOUN IS ALL AROUND USNumerous cities and counties, streets and roads, schools and other public places are named for Calhoun, a slaveholder who served as secretary of state, secretary of war, a U.S. senator, and two terms as vice president.For instance, the Calhoun State Office Building sits in the capitol complex in Columbia, South Carolina's state capital city.There are counties named for him in his home state, as well as Alabama, Arkansas, Georgia and elsewhere in the South. There is even a Calhoun County in Michigan named for him.Major streets in Columbia and Charleston, still bear his name.Despite his prominence elsewhere, Calhoun is about to become less prominent on the landscape of American higher education.The board of trustees at Clemson University, a public university, announced on June 12 that its Honors College would no longer be named after Calhoun.South Carolina's "Heritage Act" prevents renaming of buildings without legislative approval, but the honors college is an organizational unit, not a building.This is a particularly significant development given that Clemson University sits on what was once Calhoun's plantation, which his daughter and her husband, Thomas Clemson, inherited.While public memorials of Calhoun appear to be on the decline, what I find more significant—and more troublesome—is the way that Calhoun's ideology has been ingrained in the American culture and psyche, thanks in large part to the way his ideas were embraced in U.S. institutions of higher learning long after his death.I make this observation as a historian and author of a chapter for the forthcoming book Persistence Through Peril: Episodes of College Life and Academic Endurance in the Civil War South.Calhoun, who was born in 1782 and died a decade before the Civil War began, in 1850, was not only a slaveholder and an ardent defender of slavery, but a chief architect of the political system that allowed slavery to persist.More enduring than the effects of his political career—which included the annexation of Texas to expand the number of slaveholding states—are the repercussions of his political ideology.As a political theorist, Calhoun is best known for two ideas: "concurrent majority" and "nullification." A concurrent majority is the notion that a minority of the electorate—namely, one with money and property—can veto a political majority.This idea is related to his belief in nullification theory, which is the idea that a state can void federal laws. Nullification made the idea of South Carolina seceding from the nation—and the creation of the Confederacy—a political possibility and then a reality.Calhoun laid out his arguments for these ideas in his treatise "A Disquisition on Government."While some Americans defended slavery as a "necessary evil" Calhoun viewed slavery as "a positive good."He held paternalistic views of Black people as well as other non-whites, declaring: "We make a great mistake when we suppose that all people are capable of self-government." THE CALHOUN CURRICULUMCalhoun's political doctrines were taught explicitly in college classrooms for decades after his death. There are still remnants in the curriculum.His own views on nullification theory, states' rights and secession were formed when he studied at Yale University where the college's president, Timothy Dwight, introduced to him the idea that New England could leave the young nation and become a separate country. Yale named a residential college in his honor in 1931. It renamed it in 2017 after the intense pressure from students and alumni that followed the Charleston massacre at the Mother Emanuel Church.In the chapter that I am writing for Persistence through Peril, I am explaining how Calhoun's ideologies permeated Southern institutions of higher education. His views were taught at the Military Academy of South Carolina, before, during and after the Civil War. When those cadets studied the U.S. Constitution, their professors and texts emphasized Calhoun's interpretation of it.John Peyre Thomas, a Citadel graduate and Confederate Army colonel who served as professor, superintendent and later trustee at The Citadel, heaped praise upon Calhoun, having served as editor for The Carolina Tribute to Calhoun in 1857.In a speech given at Clemson University on June 22, 1897, Thomas declared, "It is conceded that Calhoun's standard in the science of government is so lofty as in some respects to be unattainable in our day and generation." THE ROAD AHEADDecades of teaching a particular doctrine do not fade easily or quickly. The United States is now witnessing another racial awakening with protests for social justice. Symbols of racism and white supremacy are being removed from higher education.On June 17, the University of North Carolina-Chapel Hill Board of Trustees reversed its 16-year moratorium on renaming buildings, put in place after the statue known as "Silent Sam" was torn down in 2018.The University System of Georgia, which includes the University of Georgia, also moved in June 2020 to review the names of its buildings. This would include the University of Georgia's Grady School of Journalism, which is named after Henry Grady, an avowed white supremacist.After Calhoun's death in 1850, his colleague in the Senate, Thomas Hart Benton of Missouri, remarked about him: "He is not dead. There may be no vitality in his body, but there is in his doctrines." He was prophetic in his words.Calhoun's ideologies fueled the Civil War, gave comfort to those who believed in the "Lost Cause" (that is, to show the Civil War in the best light possible from the Confederate point of view) and perpetuated the teaching of racist and white supremacist attitudes.Because the ideas he espoused have flourished, I believe that dismantling his legacy will take much more than just removing statues of his likeness or renaming buildings, streets and other public places named in his honor.Christian K.

Уголок 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.
