There are a few things to consider when deciding between an app and, say, a clip-on tuner.

One important invention that resulted from the discovery of the mineral acids is aqua regia, a mixture of nitric acid and hydrochloric acid in a 1:3 proportion, capable of dissolving gold. ![]() Thirteenth-century Latin alchemists, for whom the De aluminibus et salibus was one of the main reference works, were fascinated by the chlorinating properties of corrosive sublimate, and they soon discovered that when the metals are eliminated from the process of heating vitriols, alums, and salts, strong mineral acids can directly be distilled. In this process, hydrochloric acid actually started to form, but it immediately reacted with the mercury to produce corrosive sublimate. 11th–13th century ĭrawing on al-Razi's experiments, the De aluminibus et salibus ("On Alums and Salts"), an eleventh- or twelfth-century Arabic text falsely attributed to al-Razi and translated into Latin by Gerard of Cremona (1144–1187), described the heating of metals with various salts, which in the case of mercury resulted in the production of mercury(II) chloride (corrosive sublimate). ![]() Multhauf, hydrogen chloride was produced many times without clear recognition that, by dissolving it in water, hydrochloric acid may be produced.

In the early tenth century, the Persian physician and alchemist Abu Bakr al-Razi ( c. The name hydrochloric acid was coined by the French chemist Joseph Louis Gay-Lussac in 1814. The name muriatic acid has the same origin ( muriatic means "pertaining to brine or salt", hence muriate means hydrochloride), and this name is still sometimes used. Both names are still used, especially in other languages, such as German: Salzsäure, Dutch: Zoutzuur, Swedish: Saltsyra, Spanish: Salfumán, Turkish: Tuz Ruhu, Polish: kwas solny, Hungarian: sósav, Czech: kyselina solná, and Chinese: 盐酸 ( yánsuān). Etymology īecause it was produced from rock salt according to the methods of Johann Rudolph Glauber, hydrochloric acid was historically called by European alchemists spirits of salt or acidum salis (salt acid). Hydrochloric acid is an important laboratory reagent and industrial chemical. It is a component of the gastric acid in the digestive systems of most animal species, including humans. It is a colorless solution with a distinctive pungent smell.

They think they’re going to silence me?” “My antisemitic rhetoric? This is why I despise these people and you should too,” Levin said on his radio show. “Even after the heartbreaking killing of a 6-year-old Palestinian American child and a surge in violence against Muslims and Arab Americans, two nights ago Jesse Watters made vile comments that attack the dignity of all Americans, saying he’s ‘done’ with Arab Americans and Muslims,” Bates added.Ī Fox News spokesperson did not immediately have a comment.īut Levin stood by his comments Thursday night while responding to CNN’s condemnation of his remarks. “What’s more, it isn’t even the first time this week that a Fox host chose to abuse their platform and spread hate,” Bates continued, referencing Islamophobic remarks made by prime time host Jesse Watters about Arab Americans and the entire Muslim world. “Sadly, this is not the first time in recent months that a Fox News host made sickening remarks about the Holocaust.” “Lying to insult the pain that families suffered in the Holocaust has absolutely no place in America.

The rebuke came in response to Mark Levin, a right-wing talk personality and Fox News weekend host, who raged against CNN anchors Wolf Blitzer and Jake Tapper in recent days while ranting on his nationally syndicated radio show. “Not only is Fox News aligning with those who fan the flames of hate – Fox is paying their salaries,” Andrew Bates, deputy White House press secretary, said in a blistering statement, marking the second time this week the Biden administration publicly condemned the network for its hosts’ commentary. The White House denounced Fox News on Friday, blasting the right-wing network for “standing up on behalf of hate” after one of its hosts attacked the Jewish heritage of two CNN anchors over their coverage of the Israel-Hamas war. ![]() ![]() ![]() Step 5:The file will be downloaded as an M4V file, which is technically an MPEG4 file, and will be able to open in Premiere Pro or any other video program that you will use.

During testing, the team was able to eliminate 80,000 guesses per second. “Once we know that, we have a model for how that tool laid out the text and how and what information it deposited throughout the rest of the document.” From here, it is ultimately possible to simulate what the original text may have been and produce a series of potential, or likely, matches. “That tells us about how the text was laid out,” Levchenko says. The software is constructed by inferring how the original document was produced-for instance, in Microsoft Word-and then reverse engineering the specifics of the document. The tool is essentially able to automatically compare the size of the redaction and the position of the letters with a predefined “dictionary” of words to estimate what has been replaced. “It’s pretty clear to a lot of people that the letter ‘L’ is skinnier than a letter ‘M,’ and that if you redacted just the letter ‘L,’ then you might be able to tell it is different from a redaction with just the letter ‘M,’” Bland says. Plus, a new attack method they devised makes it possible to extract secret details from the redacted text.Įdact-Ray focuses on the size of glyphs (broadly, characters or letters) and their positioning. The findings, from researchers Maxwell Bland, Anushya Iyer, and Kirill Levchenko, say two of the most popular tools for redacting documents offer no protection to the underlying text at all, with the text accessible by copying and pasting it. New research from a team at the University of Illinois looked at the most popular tools for redacting PDF documents and found many of them wanting. When this redaction is done incorrectly, people’s safety and national security can be put at risk. The majority of redactions-by government officials and courts-involve placing black boxes over text in PDFs. Now that most documents are digitized, securely redacting their contents has become harder. If this didn’t work, a chunky black marker pen would do the job. For years, if you wanted to protect sensitive text in a document, you could grab a pair of scissors or a scalpel and cut out the information. ![]() |
