Manitowish Waters – The North Lakeland Discovery Center is celebrating its 25th anniversary with a series of expansion projects to help it better serve the community.

“It’s not just Manitowish Waters. It’s a regional organization. We have members, supporters and volunteers all over the Northwoods,” said Rolf Ethun, the North Lakeland Discovery Center fundraising coordinator. .

The Discovery Center aims to connect people with the Northwoods and appreciate nature. New buildings and renovations will give the center the ability to do just that.

“What elements of nature are at play and why does this matter to us today in our lives? As people learn more about the environment and the Northwoods in which they live, they tend to make better decisions about it, ”said John Heusinkveld, executive director of the North Lakeland Discovery Center.

One of the ways the Discovery Center does this is through publicly accessible programming. A few of these programs include historic canoe and pontoon trips on the lake and winter snowshoeing animal tracking activities.

“If you like being outdoors, if nature means anything to you, you should come to Discovery Center because we have a program related to it,” Heusinkveld said.

The center is building a new facility to accommodate on-site programs year-round.

Construction is slated to begin this winter if they reach their fundraising goal by then. So far, they have raised over $ 3 million, but they hope to reach $ 4 million soon thanks to the more than 500 individual donors who have contributed to the campaign so far.

“It’s extremely rewarding to feel and know that people care so much and are ready to do it,” Ethun said.

The center is less than 10% of its fundraising goal. Once this goal is achieved, they can begin construction of the building that will serve the inhabitants of the region.

If you would like to donate to the Discovery Center, you can call them or find more information on their website.

NIAGARA DISCOVERIES: 1916 Automobile Parade Celebrated United States-Canada Cooperation | Lifestyles Sat, 11 Sep 2021 18:00:00 +0000

Even though US citizens are allowed to return to Canada, certain requirements are still necessary to cross the border. This was also true about 100 years ago. In the History Center’s collection are several photos, some of which are captioned, showing a parade of automobiles that started in Buffalo and ended in Niagara Falls. Although legends mention several men associated with the Automobile Club of Buffalo, there is no indication of when or why the parade took place. After doing some research based on the names of the men and the approximate date of the automobiles, the story behind the auto parade emerged.

By the 1910s, although automobiles were still considered a luxury that could only be enjoyed by a small percentage of the population, they were becoming more and more common and their owners were pushing for improved road conditions, Additional “guide signs” and the use of illuminated lights. cars when driving at night (this law was finally passed by the New York State Legislature in 1915 after several years of defeat).

The Automobile Club of Buffalo was founded in 1905 to promote camaraderie and safety between owners and drivers of the new “horseless cars”. Based at the Lafayette Hotel in Buffalo in 1916, the club had 4,000 members across western New York State and had built a new “country club” in Clarence for its members to enjoy. However, there was one issue the club hoped to resolve that was directly related to the motor show in the photographs.

At that time, if a New York State motorist wanted to drive in Ontario, Canada, he had to obtain a driver’s license from that province. Conversely, if an Ontario motorist wanted to drive in New York State, they would have to obtain a New York driver’s license. With the proximity of the two countries, and the desire of motorists to move freely between them, this requirement has created an obstacle, especially for tourism.

Beginning in about 1909, the leaders of the New York State Motor Federation and the Ontario Motor League began asking their respective legislatures for an “automatic reciprocity agreement” between the state and the province to allow motorists to cross the road. Canada-US border by requiring only one driver. Licence. This long-awaited resolution finally became official on May 11, 1916, and as soon as the news was received, plans were made for a celebratory parade.

At 10 a.m. on Friday, May 19, 1916, a motorcade of more than 20 cars left Lafayette Square in Buffalo and headed north on Main Street to Niagara Falls Boulevard. Along the way more and more automobiles joined until the line contained over 50 vehicles and was over a mile long when it finally reached Niagara Falls at noon.

A similar procession had formed on the Canadian side. The leading cars of the two nations, containing representatives of state and provincial governments and automobile clubs, met in the middle of the steel arched upper bridge (aka “the honeymoon bridge”) where official documents from the reciprocal agreement was exchanged, as were the flags. of each country. The men then changed positions in the cars, with the Americans joining the Canadian procession and the Canadians joining the American procession. The American column then passed through Canada and combined with this parade while the Canadian cars did the same on the American side. The Canadian contingent then returned to the US side and a total of over 100 cars containing over 500 passengers passed through Niagara Reservation State Park. The entire convoy then returned to Canada, through Queen Victoria Park and to the Clifton Inn for lunch.

Because the reciprocal agreement was intended to encourage tourism, the permits were only valid for 21 days. Motorists with long-term business or family relationships that required frequent trips across the border still needed to obtain permits from both countries. But this joint cooperation between the United States and Canada ultimately led to the construction of the Peace Bridge in 1927, which further facilitated the exchange of tourism and business across this international border.

However, it remains a mystery. Can anyone tell us something about the roller coaster that is in the background of the photograph accompanying this piece? If you can, please email the History Center at

Discovery and Overall Creek Receive Award School Status Wed, 08 Sep 2021 21:22:30 +0000

Discovery School and Overall Creek Elementary received the Tennessee award school designation, with Erma Siegel Elementary missing the designation by simple fractions of a point. Award status is the main honor a school can earn in Tennessee.

The annual award school designation identifies schools that improve overall student academic achievement and student growth for all students and for groups of students. This is the fifth year in a row that the state has awarded the Reward School distinction to Discovery School and the second year in a row to Overall Creek. About 20% of the state’s schools have achieved award status historically.

“I think this designation is a direct response to the emphasis placed on student learning by our teachers and administrators,” says Dr Trey Duke, school principal for the town of Murfreesboro. “We congratulate the staff and students of Discovery and Overall on receiving this designation. ”

Murfreesboro City School teachers and support staff constantly review the needs of each student in their care and continue to focus on serving the child as a whole.

Murfreesboro City Schools is a school district proud of its thirteen schools and over 9,400 students.

Legal discovery could haunt Buffalo school radars at program end Wed, 01 Sep 2021 22:58:00 +0000 A New York-based lawyer representing a driver was surprised and alarmed by what she describes as a “kangaroo court system” with the program’s cameras.

BUFFALO, NY – Wednesday, September 1 marked the official end of the highly controversial school zone radar program in the city of Buffalo. He was dismissed by the city council as he challenged Mayor Byron Brown on this issue.

2 On Your Side has an update on the program and another legal blow against the city on this very painful subject.

First, a city spokesperson pointed out that the cameras had not been active for weeks and added that although only a few were removed, the rest will be removed before schools in the city start. town next week.

In the meantime, the tracing of crosswalks near schools is underway along with new digital speed warning signs that will likely replace cameras, but there are no tickets with these.

So let’s get back to speed cameras, for which some people have been fined $ 50 for an offense over 15 mph. By the way, the zones have now increased to 20.

A New York-based lawyer representing a driver who got two tickets in March was frustrated when the city failed to provide basic information about the program. She filed an access to information request and was surprised and alarmed by what she describes as a “kangaroo court system” with these cameras installed by a Swedish supplier.

Lawyer Karina Tefft said the Hearing Officer agreed with her reasoning and dismissed her client’s tickets when she pointed out that she found out that the city’s system worked automatically and did not had no operator to check and verify the accuracy of the cameras and actual logs to record this verification test.

Tefft says this goes against the basic legal principle of due process and national vehicle and traffic law. For example, a police officer may be questioned in court when he writes a ticket or uses a radar gun or other equipment to measure a vehicle’s speed.

Tefft says: “This is so important because it means that essential protective measures were not used at any time to ensure that speed zone radars were accurate. And the city can’t prove the speed camera records were accurate, they can’t provide a foundation in evidence to argue that the drivers who got those tickets were even speeding. “

Tefft argues that all tickets should be thrown away and the city should reimburse anyone affected by any of them. Some estimates put it at nearly $ 2 million.

A city spokesperson said, as usual, that they were not commenting on the ongoing litigation against the city.

This dispute is a class action lawsuit in which information from Tefft obtained through the Freedom of Information Act will be used in the filing. It remains to be seen what the judge will decide. There is another class action lawsuit that could also consider it.

And Karina Tefft says it’s possible the Buffalo experiment could be used to tackle similar speed zone radar systems across the country, which could haunt City Hall for some time.

4-year-old girl discovers rare stingless bees in California Sat, 28 Aug 2021 21:17:00 +0000

PALO ALTO, Calif. (CBS NEWS) – People who study insects have been in turmoil lately after a most unlikely discovery – and the amateur entomologist who made it.

A 4-year-old girl with a gift for nature found two colonies of rare stingless bees, creatures scientists thought were long extinct and no adults had managed to notice.

Annika Arnout’s mastery of nature baffles many adults, in large part thanks to biologist Targe Lindsey. He is her tutor, brought in by her parents when she was 3 months old so Annika could explore nature in her neighborhood in Palo Alto, California.

But this year Annika – now a seasoned naturalist – found tiny bugs that weren’t just any bugs. His discovery was forwarded to the Plant Parasite Diagnostics Branch of the California Department of Food and Agriculture, where Dr. Martin Hauser is a senior insect biosystematist.

The insects found by Annika are stingless bees that aren’t meant to be here – they live in Brazil and are much smaller than the average bee. Annika found the bugs in an undisclosed location, which she did not disclose in order to protect her “special place”.

Decades ago, the United States Department of Agriculture researched bees to increase the size of fruit and vegetable crops.

“In 1950 the USDA asked a Brazilian researcher to send them bee colonies to see, to have alternative pollinators,” Hauser said. “He sent them in the 1950s to Gainesville, Florida, Logan, Utah, and Davis and Palo Alto. And he said all the bees died in a year.

“They didn’t like the cold in Utah. They couldn’t compete in Florida, ”he added.

They also went to Stanford professor George Shafer in Palo Alto. According to Hauser, only the colonies sent to Dr. Shafer survived Palo Alto for eight years. The bees went unnoticed for 70 years, until a 4-year-old girl noticed them this year.

“It shows us that when you get a new perspective with a child’s eyes, she just looked at that and she – there’s something different about these bees,” he said.

The stingless bees Annika had found were certainly the descendants of those imported as USDA pollinators. They were presumed dead and had no representative in Dr Hauser’s vast collection.

In fact, Hauser hadn’t even heard of Brazil’s stingless bees until almost 20 years ago. He said he received a quote from a “pest control man” in Palo Alto and initially thought it was a practical joke.

The guy was Richard Schmidt, who was asked by a Palo Alto owner to get rid of the buzzing bugs in his garden. Schmidt says he didn’t kill them – instead, he sent a few to the county agriculture department.

“I had never seen them before,” Schmidt said. “I captured a few, I sent them to our county [Agriculture] department. They didn’t know what they were. And so, they sent it to the state.

Hauser later realized that his identification was wrong and sent the bees to various experts around the world, but they were all puzzled.

“They all said, ‘Where did you find him?’ and I said, ‘Palo Alto’, ”he said. “And finally he found out that it was a species described in 1900 by a German bee researcher.”

After it cracked the case, the tree toppled over and the bees were gone. Only one remaining piece has been incorporated into his collection – that’s all he had to do until this year, when Annika’s Bees became social media stars on iNaturalist, a website that posted photos taken by Targe.

Hauser was impressed with Annika’s discovery.

“I was very impressed that she found two settlements,” he said. “It’s very amazing that she found two and all the scientists didn’t find one.”

For Dr Hauser, if bees are a rare find, so is Annika. It was important for him to meet her, and he was happy to do so. He encourages children to be more curious about nature like he was when he was a child.

When they first met, he gave her the biggest book of insects he could find with a sweet note that read, “To Annika, for many more discoveries to come.”

But Annika’s bees aren’t in the book. Even after more than 100 years of chance sightings, the bees still go unnamed, although it has been suggested that the stingless bees of Brazil are referred to as “Annika’s bees.”

Twitter Spaces is testing new discovery feature to show which your friends are listening to Wed, 25 Aug 2021 12:19:45 +0000

Twitter Spaces is testing a feature that will allow users to better explore audio-only chat rooms. Previously, users could only see spaces of the people they follow if they were hosting. Now users will be able to see the Spaces that the people they follow are listening to. Users also have the option to hide the spaces they listen to from their subscribers. Twitter said it is “experimenting” with the new Spaces features with a few users on iOS and Android, so don’t expect the feature to roll out immediately to everyone.

Through a tweet, Twitter Spaces announced that it is experimenting with a new feature that lets you see what the users you follow are listening to, at the top of your timeline. The tweet also mentions that users will be able to hide the spaces they listen to from their followers if they wish. Users can activate this feature by visiting the Settings and privacy menu and navigate to Privacy and Security option. Once there, in the The spaces menu users will see an option Let subscribers see the spaces you listen to. However, users should note that they will always be visible to other users in the spaces they are listening to.

Earlier this month, Twitter announcement update its API v2 to make it easier for developers to find spaces. Developers will now be able to “search for live or scheduled spaces using criteria such as Space ID, User ID, or Keyword.” Essentially, developers could also redirect users to a space directly from other third-party apps.

In addition, Twitter also has announcement that it expand the ability to add more co-hosts to Twitter Spaces. Hosts will now be able to nominate up to two co-hosts for a space. In total, a space can now have one host, two co-hosts and up to 10 speakers. Co-organizers will be able to invite speakers, manage requests, remove attendees, pin Tweets, and more.

Canada Silver Cobalt Announces Interceptions of Up to 2.22% Cobalt in Castle East Update Mon, 23 Aug 2021 15:47:49 +0000

News and research before you hear about it on CNBC et al. Claim your 1-week free trial for StreetInsider Premium here.

The excellent dosages of cobalt combined with the high grade silver support Canada Silver Cobalt’s goal of becoming a major producer of silver with significant cobalt by-products.

Coquitlam, British Columbia – (Newsfile Corp. – August 23, 2021) – Canada Silver Cobalt Works Inc. (TSXV: CCW) (OTCQB: CCWOF) (FSE: 4T9B) (the “Company” or “Canada Silver Cobalt”) is pleased to announce significant assays of high grade cobalt from its Castle East discovery where the Company completed 42,000 meters of a 60,000 meter drill program aimed at significantly increasing its 43-101 resource estimate.

With additional results provided by the pending analysis laboratories, the Company is now able to provide selected cobalt interceptions as well as previously announced silver results for the Big Silver, 17M and 50 West zones with grades ranging from up to 2.22% cobalt and 89,853 grams / tonne of silver. (2,621 ounces / tonne of Ag).

These marked areas are distinct from the Robinson area which was the basis of the existing May 2020 resource estimate. The Big Silver and 17M areas are two different structures believed to be subparallel and have a north-northeast orientation with the interception of the Big Silver CS-20-39 discovery hole located 60 m southeast of the Robinson CA-11-08 zone discovery hole. Another distinct structure located 650 m west of the Robinson CA-11-08 discovery hole is the 50 West Vein.

“With recent drilling, we have seen spectacular results in silver, notably up to 89,853 g / t silver (almost 9% silver). However, this drilling program has also been very successful on the side of the cobalt. The cobalt contents we obtained with Big Silver are even higher than our first resource published in May 2020. We believe that cobalt will remain a critical mineral in the future due to its role in the creation of high-end EV batteries, and we are ramping up our business to capitalize on cobalt and our proprietary Re-2Ox extraction process in the coming years, ”said Matt Halliday, P.Geo., President and COO.

Cobalt activities

The demand for cobalt has increased in recent years due to its use in batteries in the rapidly expanding electric vehicle sector. Research firm Roskill, in a recent report, predicts that demand for cobalt will grow at a compound annual growth rate (CAGR) of 7% by 2030 – supported by the adoption of electric vehicles around the world and a medium-term healthy demand for portable electronics in the middle of the roll. outside of 5G technology (Cobalt: Roskill opening speech at Cobalt 2021 – Roskill Conference).

The Company’s Castle Mine property, which is located in the high-grade cobalt bay area surrounding the town of Cobalt, Ontario, places it in a prime position to capitalize on this trend. In 2018, laboratory tests at SGS Canada showed that the company’s proprietary Re-2Ox closed-loop hydrometallurgical extraction process can produce premium cobalt sulfate (22.6% cobalt sulfate hexahydrate) that meets industry specifications for electric vehicle batteries. The process is environmentally friendly and does not need to use a smelting process commonly used by cobalt producers and battery recyclers. Re-2Ox tests, using concentrate from the Castle mine, demonstrated recoveries of cobalt, nickel and manganese of 99%, 81% and 84% respectively, in addition to removing 99% of the arsenic (press releases May 31 and August 15, 2018).

The Company continues to optimize the Re-2Ox process for extracted materials and recycled batteries and to determine whether it can be used for rare earth extraction. In addition, work is underway at SGS Canada for the design and construction of a Re-2Ox pilot plant. The Company expects the Re-2Ox process to be an integral part of its production of cobalt and other base metals for the expanding cobalt market.

Updating resources

Drilling underway in the Castle East area aims to identify new veins to allow significant expansion of the existing resource. The program was very successful as drilling uncovered a total of seven new high-grade silver vein systems, including Big Silver, which is even richer than the original Robinson Zone discovery. These seven new vein systems, along with any new ones discovered during the remaining 18,000 meters of the drill program, will help broaden the resource estimate planned for the first quarter of 2022.

The company’s first resource estimate (published in a May 28, 2020 press release) identified two panels of what we call the “Robinson Zone” which contains an average silver grade of. 8,582 g / t (250 ounces / ton) in a total of 27,400 tonnes of material for a total of 7.56 million inferred ounces silver. This uses a cut-off grade of 258 g / t AgEq. Please note that Mineral Resources that are not Mineral Reserves have not demonstrated economic viability.

The Castle property is located near the town of Gowganda, in the prolific silver and cobalt mining district (also known as the cobalt camp) in Ontario, Canada. The property is located 15 km east of Aris Gold Corp’s Juby gold deposit, 30 km due south of Alamos Gold’s Young-Davidson mine, 75 km southwest of the Kirkland Lake Macassa complex Gold and 100 km southeast of new gold discoveries in the Timmins West area. .

About Canada Silver Cobalt Works Inc.

Canada Silver Cobalt Works Inc. recently discovered a large, high-grade silver vein system at Castle East, located 1.5 km from its 100% owned Castle mine near Gowganda in the Silver Mining District -prolific, world-class cobalt from Northern Ontario. This discovery has the highest silver resource grade in the world, with recent drill intersections of up to 89,853 grams / tonne silver (2,621 oz / tonne Ag). A drilling program is underway to expand the size of the deposit with an update of the resource estimate scheduled for the first quarter of 2022.

In May 2020, based on an initial small drill program, the Company released the region’s first 43-101 resource estimate which contained a total of 7.56 million ounces of silver in inferred resources. , comprising very high grade silver (8,582 grams per ton one- or 250.2 oz / ton) in 27,400 tonnes of material from two sections (1A and 1B) of the Castle East Robinson Zone, beginning at a vertical depth of about 400 meters. Note that mineral resources that are not mineral reserves have not demonstrated their economic viability. Please refer to the Canada Silver Cobalt Works press release dated May 28, 2020 for the resource estimate. Report reference: Rachidi, M. 2020, NI 43-101 Technical Report Mineral Resource Estimate for Castle East, Robinson Zone, Ontario, Canada, with an effective date of May 28, 2020 and a signing date of July 13 2020.

Canada Silver Cobalt Castle’s flagship silver-cobalt mine and the 78 km² Castle property have strong exploration potential for silver, cobalt, nickel, gold and copper. With underground access to the wholly-owned Castle Mine, an exceptional discovery of high-grade silver at Castle East, a pilot plant to produce cobalt-rich gravity concentrates on-site, a processing facility (TTL Laboratories) in the town of Cobalt and a hydrometallurgical process known as Re-2Ox (for the creation of technical grade cobalt sulfate as well as nickel-manganese-cobalt (NMC) formulations), Canada Silver Cobalt is strategically positioned to become a leader Canadian leader in silver-cobalt space.

New findings remove major barriers to conception Sun, 22 Aug 2021 21:49:56 +0000

There are many obstacles that need to be overcome before quantum computers become mainstream. However, UNSW in Sydney’s new technology to control millions of spin qubits goes even further.

The team’s latest research has been published in Science Advances. He claims to have solved one of the main obstacles to large-scale quantum computing. The problem is, you can control millions of cubits without taking up a lot of space.

Dr Jarryd Pla, quantum engineer at the Faculty of Electrical and Communications Engineering, said: Recent Videos In terms of development, “quantum computers have promised to revolutionize a wide range of areas essential to our daily lives, but current generation quantum computers are major with only a handful of qubits. It is a proof of device. “

He continued. “… Deep in my heart there has always been this lingering question of how to go from controlling a few cubits we can now to controlling millions of qubits. Will be needed to maximize the potential of. “

Traditional quantum computers rely on a microwave magnetic field through the current flowing through the control wire next to the qubit. The problem is that the qubit can only be controlled near the wire, as the controlling magnetic field quickly decreases with distance. To control more qubits, the computer needs more wires, which take up valuable space and generate a lot of heat. For quantum computers that require cryogenic temperatures of around -270 ° C to operate, the generation of additional heat poses major problems.

Quantum computing details

Efficient qubit control

The UNSW team found a way to completely eliminate the lines of control.

Mr Pula said: “In the new result, we found a new way to remove the control line and provide a field that can cover the entire quantum chip. Place a small crystal on the device and excite it with low power. Microwave. The crystal resonates. It can generate a uniform magnetic field over the entire region of the chip and reach millions of cubes. Because this magnetic field is uniform, all the cubes rotate at the same speed. It is reliable. Is essential to improve and avoid mistakes.

The crystal in question is called a dielectric resonator. The resonator reduces the microwave wavelength to less than a millimeter and efficiently converts microwave power into a magnetic field that controls the spin of the qubit.

In particular, the new method does not require large amounts of energy due to the magnetic field and reduces heat generation.

“I’m really excited because the potential of this new technology was one piece of a puzzle,” said Professor Andrew Zurack, professor of quantum engineering science and colleague at Dr Pula’s University. To make sure we’re producing the millions of cubits that we’ll need in the future, but now it shows how to control those cubits. “

Dr Jarryd Pla continues: For real It can affect your life. This result brings us one step closer to realizing all that potential. “

The engineer gave a full summary of the Science Alert study site.

The concept of chemical elements Sun, 22 Aug 2021 12:21:10 +0000
Through Robert M. Hazen, Ph.D., George Mason University

The nature of the chemical elements themselves is very complicated. Long before the existence of atoms was proven, there were still chemical researchers around the world looking for useful compounds. And some of the substances they found seemed more basic than others. These “elements” cannot be broken down into other substances by any normal physical or chemical means.

Chemical elements are the most basic substances in nature. (Image: Tonhom1009 / Shutterstock)

Most famous chemical elements

Many people may know that water can be broken down with an electric current. And it breaks down into two gases: hydrogen and oxygen. But no matter what is done, it doesn’t seem possible to break down hydrogen and oxygen into simpler compounds. They seem more basic. They are chemical elements.

Ancient cultures knew of at least ten different chemical elements. Most of them have been found in their original condition, most of them have been found as metals. There are precious metals like copper, silver, and gold. They are common enough to be noticed; they are tough enough to be useful; they are rare enough to be valued.

Platinum is also a precious metal. Interestingly, platinum was not recognized in Europe or Asia, but it was used by pre-Columbian people in the New World, in part because platinum nuggets could be found in the stream beds of some parts. from South America.

Natural chemical elements

Other metals are also rarely found as native elements under unusual circumstances. There is iron, found in the form of meteorites. Small amounts of lead, small amounts of mercury can be found in certain types of places. And so these also occur uncombined in nature; they are also natural elements. These metals, along with tin and antimony, could be produced in a fire from ordinary ores.

Indeed, some of these elements may have been discovered by chance. An ore just falls into a fire, and a little bit of that metal, antimony or tin, could be pulled out that way. There are also non-metallic elements found in nature. Carbon comes from charcoal and sulfur from volcanoes. Beautiful yellow sulfur crystals can be found near the mouths of some volcanoes. All these elements, moreover, are still extracted in large quantities today.

Period of alchemy and the discovery of chemical elements

From the 12th century to the 16th century was the period of alchemy, where various scholars learned to separate a few other elements using intense fires. New elements discovered during this time include arsenic and zinc, bismuth and phosphorus. Between 1735 and 1805, chemists devised new techniques to purify and characterize more than two dozen new elements. This research goes hand in hand with advances in mineralogy.

Many of the new elements were discovered by studying the minerals by wet chemical analysis, where the minerals were dissolved or broken up, or by torch analysis, where a very hot flame was used to melt and fuse various parts of the minerals. And from time to time, a new element appeared as well.

The important elements – nickel, cobalt, magnesium, chromium, molybdenum, tungsten, uranium – were all discovered during this period. Also, during this period was the first isolation of gaseous elements. Hydrogen, nitrogen and oxygen were all isolated between 1772 and 1774.

The most spectacular of these discoveries was made by British chemist Joseph Priestley, who lived from 1733 to 1804. It was in 1774 that Priestley submitted mercury oxide, or HgO, a common mineral that can be collected on the surface of the Earth. .

He subjected it to a temperature of about 450 degrees centigrade, which caused a puddle of mercury to form at the bottom of his flask and the release of a gas, which turned out to be oxygen. .

He collected this gaseous oxygen in his containers, and he discovered that it is the gas that is essential for all combustion processes. Indeed, he wrote: “What surprised me more than I can express is that a candle was burning in the air with a remarkably bright flame. So he had discovered a pure source of oxygen.

Using the battery to discover new chemical elements

The battery provided an important new technique called electrolysis. And by this electrolysis technique, new elements can be produced and isolated. The battery was invented by Luigi Galvani, who placed an alternating sequence of plates – for example, zinc, silver, zinc, silver – in an acid bath to obtain an electric potential.

Electrolysis works like this: a chemical compound is dissolved in an acid bath, then this acid bath is subjected to electric current. These alternating metal plates create a positive electrode and a negative electrode.

Metals often settle on the negative side, the anode side, while non-metals concentrate on the cathode, the positive side, of this acidic bath. And in this way, new elements can be isolated, one going to each of the two electrodes in some cases.

The use of drums to discover new elements began in 1797. British chemist Sir Humphry Davy was a great lecturer in London. He used increasingly powerful batteries to separate potassium and sodium, boron, calcium, barium, cadmium, all very important elements which were first separated and isolated by Davy at the using its battery.

Common questions about the concept of chemical elements

Q: What are the chemical elements?

Chemical elements are basic substances in nature discovered by researchers before the existence of atoms was proven. These “elements” cannot be broken down into other substances by any normal physical or chemical means.

Q: How was oxygen discovered?

Oxygen, among the best known chemical elements, was first discovered by chemist Joseph Priestley. He was able to extract pure oxygen from the mineral mercury oxide.

Q: Who was Sir Humphrey Davy?

Sir Humphrey Davy was a British chemist who discovered many chemical elements such as calcium, barium, cadmium, sodium and potassium using batteries that provide a technique called electrolysis.

Cops cripple ‘Wa Syndicate’ with drug discovery buried near house Sun, 22 Aug 2021 07:47:00 +0000

PADANG BESAR: A husband and wife who are believed to be drug traffickers and part of the “Wa Syndicate” were arrested after police found drugs buried near their home here.

Padang Besar District Police Chief Superintendent Saifudin Aslin Abbas said police seized 4.17 kg of syabu and ganja worth RM84,191 and arrested four suspects in three separate raids .

“A local woman was arrested on August 16 following intelligence gathered by the district police headquarters, Narcotics CID (NCID) with the assistance of the Perlis NCID since July,” he told reporters. Sunday August 22.

“The 21-year-old woman, who is the union mastermind wife, was detained outside a stall here.

“She handed over a plastic container with allegedly syabu crystals weighing 52.72g during an inspection at 12:15 pm,” he said.

He said information obtained during the arrest led to the second raid at 2:45 p.m. the next day (August 17) at a house here.

“Police caught two suspects, a 35-year-old Thai man who was the brain, and a 27-year-old resident.

“Syabu weighing 2.149 kg and 1.972 kg of ganja kept in a cloth bag were found buried near the suspects’ house during an inspection,” he said, adding that both had tested positive on the methamphetamine.

In the third raid at 9 p.m. on Friday August 20, he said police caught another suspect, a 20-year-old Thai man, who tested positive for methamphetamine in an unnumbered house here.

Saifudin said police also seized a car worth around RM40,000 under the Dangerous Drugs (Forfeiture of Property) Act of 1988.

He said all suspects had been arrested and were under investigation under section 39B of the Dangerous Drugs Act 1952 and section 15 (1) (a) of the same. law.

A check also revealed that two suspects arrested in the second raid had a history of drug and criminal offenses, he added. – Bernama
