美元指数重拾跌势 人民币中间价报6.5384上调143点

4月7日,人民币(6.54130.00180.03%)中间价报6.5384,上调143点,上一交易日中间价报6.5527,在岸人民币上一交易日收报6.5501。

美元指数(92.34110.01910.02%)为何重拾跌势?

尽管高盛策略师暂时退出做空美元的策略,但该投行同时指出,未来几周之后可能会有更多做空美元的机会,因为交易员们预计随着欧洲大陆疫情好转,“欧洲经济活动可能出现复苏”。

疫苗接种将在4月和5月显著加快,而过去的经验表明,欧洲等地的封锁政策将推动该地区确诊人数快速下降。欧洲经济加速增长,应有助于在一定程度上消除与美国的差异,并在总体上支撑大宗商品价格和风险资产。高盛策略师指出:“有明确证据表明欧洲的疫情正在得到控制,这可能会导致新的美元空头建议。”即便上周五公布的非农就业数据,及本周一公布的服务业活动指数均显示出经济强劲增长,但美元指数在本周仍旧下跌,可能表明目前市场已消化了大部分乐观前景。

道明证券外汇策略全球主管马克•麦考密克在一份客户报告中写道:“虽然美国看起来确实与众不同,但随着时间的推移,疫情正常化意味着世界其他国家将趋同。”他表示,美元汇率水平现在已经超过了美国以外的市场,而全面增长预期意味着美元在近期的上行趋势中“有暂停的空间”。

央行工作论文建议:适时建立人民币汇率期货市场

央行网站发布的工作论文建议,研究各类汇率衍生品对汇率形成作用,适时建立人民币汇率期货市场,或引导境内相关主体有效利用离岸期货市场规避汇率风险。

论文称,考虑到人民币期货市场发展对人民币汇率价格的合理形成、掌握人民币汇率定价权和促进人民币国际化具有重要作用,在当前人民币在岸市场与离岸市场日益均衡发展、境内外各类市场主体逐渐形成人民币汇率双向波动预期的背景下,建议进一步探索构建以国内大循环为主体、国内国际“双循环”相互促进的新发展格局下的人民币汇率全球定价形成机制:一是不断完善人民币在岸市场的定价机制,研究各类汇率衍生品对汇率形成作用,适时建立人民币汇率期货市场,或引导境内相关主体有效利用离岸期货市场规避汇率风险;二是加强对全球人民币流动、资产配置和价格变动的监测,健全人民币汇率风险的宏观审慎管理体系,稳步推进人民币国际化。

评论:人民币汇率近期波动属正常健康调整

  近期人民币汇率回落,一是欧洲疫情出现第三波传染,市场避险情绪重新抬头;二是美国通胀预期上升,美债收益率上行,中美债收益率差收敛;三是疫苗接种加新刺激计划,提振美国经济复苏预期,美元指数不跌反涨;四是货币提前紧缩预期抬头,以美股为代表的风险资产价格剧烈震荡,新兴市场重现资本外流;五是大国博弈依然激烈,凸显国际环境日趋复杂严峻。

汇率是相对价格,研判汇率走势不仅要看本国还要看海外会发生什么。中国在疫情防控常态化的前提下,经济社会活动正在进一步加快恢复,只是外部因素发生了一些变化。但这仍属于健康、正常的调整,反映人民币汇率步入了双向波动的新常态。

    A year ago today, things went from bad to worse for Boeing
    <a href=https://kra23c.cc>kraken тор</a>

    At 5 p.m. PT on January 5, 2024, Boeing seemed like a company on the upswing. It didn’t last. Minutes later, a near-tragedy set off a full year of problems.

    As Alaska Airlines flight 1282 climbed to 16,000 feet in its departure from Portland, Oregon, a door plug blew out near the rear of the plane, leaving a gaping hole in the fuselage. Phones and clothing were ripped away from passengers and sent hurtling into the night sky. Oxygen masks dropped, and the rush of air twisted seats next to the hole toward the opening.
    https://kra23c.cc
    kraken тор
    Fortunately, those were among the few empty seats on the flight, and the crew got the plane on the ground without any serious injuries. The incident could have been far worse — even a fatal crash.

    Not much has gone right for Boeing ever since. The company has had one misstep after another, ranging from embarrassing to horrifying. And many of the problems are poised to extend into 2025 and perhaps beyond.

    The problems were capped by another Boeing crash in South Korea that killed 179 people on December 29 in what was in the year’s worst aviation disaster. The cause of the crash of a 15-year old Boeing jet flown by Korean discount carrier Jeju Air is still under investigation, and it is quite possible that Boeing will not be found liable for anything that led to the tragedy.
    But unlike the Jeju crash, most of the problems of the last 12 months have clearly been Boeing’s fault.

    And 2024 was the sixth straight year of serious problems for the once proud, now embattled company, starting with the 20-month grounding of its best selling plane, the 737 Max, following two fatal crashes in late 2018 and early 2019, which killed 346 people.

    Still the outlook for 2024 right before the Alaska Air incident had been somewhat promising. The company had just achieved the best sales month in its history in December 2023, capping its strongest sales year since 2018.

    It was believed to be on the verge of getting Federal Aviation Administration approval for two new models, the 737 Max 7 and Max 10, with airline customers eager to take delivery. Approvals and deliveries of its next generation widebody, the 777X, were believed to be close behind. Its production rate had been climbing and there were hopes that it could be on the verge of returning to profitability for the first time since 2018.

    Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024
    <a href=https://kra23c.cc>kraken tor</a>

    A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.

    These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earth’s diversity.

    “Scientists estimate that we’ve identified only one-tenth of all species on Earth,” said Dr.
    Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.

    https://kra23c.cc

    “While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem,” Bennett said.

    Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean

    “South African reefs present notoriously difficult diving conditions with rough weather and intense, choppy waves — we knew we only had one dive to find it,” underwater photographer and marine biologist Richard Smith said in a statement.
    “This species is also quite cryptic, about the size of a golf tee, but luckily we spotted a female camouflaged against some sponges about a mile offshore on the sandy ocean floor.”

    The researchers involved in describing the new species chose nkosi as its name. A reference to the local Zulu word for “chief,” the name reflects the species’ crown-like head shape and acknowledges South Africa’s KwaZulu-Natal province where it was found.

    The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?
    <a href=https://kra23c.cc>kra25 cc</a>

    Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.

    The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.
    https://kra23c.cc
    kra23 cc
    The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.

    So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?

    In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.

    Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
    But does that still hold true in 2024?

    According to aviation safety experts, it’s an old wives’ tale.

    “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”

    “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.

    Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

    On a long-dormant pad in Florida, a rocket that could challenge SpaceX’s dominance is poised to launch
    <a href=https://kra23s.cc>kraken вход</a>

    On a Florida launchpad that has been dormant for almost two decades, a new, roughly 320-foot (98-meter) rocket — developed by Jeff Bezos’ company Blue Origin — is poised for its maiden flight.

    The uncrewed launch vehicle, called New Glenn, will mark Blue Origin’s first attempt to send a rocket to orbit, a feat necessary if the company hopes to chip away at SpaceX’s long-held dominance in the industry.

    New Glenn is set to lift off from Cape Canaveral Space Force Station as early as next week.
    https://kra23s.cc
    kraken зеркало
    The rocket, which stands about as tall as a 30-story building, consists of several parts: The first-stage rocket booster gives the initial thrust at liftoff. Atop the booster is an upper rocket stage that includes a cargo bay protected by a nose cone that will house experimental technology for this mission.

    And, in an attempt to replicate the success that SpaceX has found reusing rocket boosters over the past decade, Blue Origin will also aim to guide New Glenn’s first-stage rocket booster back to a safe landing on a seafaring platform — named Jacklyn for Bezos’ mother — minutes after takeoff.

    Like SpaceX, Blue Origin will seek to recover, refurbish and reuse first-stage rocket boosters to drive down costs.

    For this inaugural mission, a smooth flight is not guaranteed.

    But the eventual success of New Glenn, named after storied NASA astronaut John Glenn, is instrumental to some of Blue Origin’s most ambitious goals.

    The rocket could one day power national security launches, haul Amazon internet satellites to space and even help in the construction of a space station that Blue Origin is developing with commercial partners.

    Most plane crashes are ‘survivable’
    <a href=https://kra23c.cc>kraken вход</a>
    First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”

    For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.

    The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.
    https://kra23c.cc
    kra23 cc
    Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.

    And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.

    Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.

    Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
    Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.

    His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

    Chile’s President Boric leads journey to South Pole in historic trip
    <a href=https://kra23s.cc>Кракен тор</a>

    Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.

    Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.

    He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

    Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.

    It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.

    While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
    Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.

    “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.

    What New Glenn will do
    In some ways, New Glenn has already made its mark on the launch industry. Blue Origin has for years pitched the rocket to compete with both SpaceX and United Launch Alliance — a joint venture of Boeing and Lockheed Martin that buys engines from Blue Origin — for lucrative military launch contracts.
    <a href=https://omgprice10.com>омг</a>
    The US Space Force selected Blue Origin, ULA and SpaceX in June to compete for $5.6 billion worth of Pentagon contracts for national security missions slated to launch over the next four years.
    Blue Origin also has deals with several commercial companies to launch satellites. The contracts include plans to help deploy Amazon’s Kuiper internet satellites and a recently inked deal with AST SpaceMobile to help launch the Midland, Texas-based company’s space-based cellular broadband network.

    New Glenn could also be instrumental in building Blue Origin’s planned space station, called Orbital Reef. Blue Origin and it commercial partners, including Sierra Space and Boeing, among others, hope the station will one day provide a new destination for astronauts as the International Space Station is phased out of service.

    New Glenn vs. other powerful rockets
    New Glenn packs significant power. Dubbed a “heavy-lift” vehicle, its capabilities lie between SpaceX’s Falcon 9 rocket and the more powerful Falcon Heavy launch vehicle.

    SpaceX’s workhorse Falcon 9, for example, can haul up to 22.8 metric tons (50,265 pounds) to space. While New Glenn is capable of carrying about double that mass, it may also be roughly the same price as a Falcon 9: reportedly around $60 million to $70 million per launch.

    “I think in order to compete with Falcon 9, you have to go head-to-head or better on price,” said Caleb Henry, the director of research at Quilty Space, which provides data and analysis about the space sector.

    The question, however, is whether Blue Origin will be able to sustain a competitive price point, Henry added.

    Still, one feature that makes New Glenn stand out is its large payload fairing, or nose cone. The component protects the cargo bay and is a whopping 23 feet (7 meters) wide — nearly 6 feet (2 meters) larger than that of SpaceX’s Falcon 9 or Falcon Heavy.

    Henry said Blue Origin likely opted to outfit New Glenn with such a large fairing in order to help fulfill Bezos’ vision of the future.

    What’s on board this flight
    Blue Origin had planned to launch a pair of Mars-bound satellites on behalf of NASA for the first flight of New Glenn.

    But delays with the rocket’s development prompted the space agency to change course, moving that flight to this spring at the earliest. So for this inaugural flight, Blue Origin opted to instead fly a “demonstrator” that will test technology needed for the company’s proposed Blue Ring spacecraft — which will aim to serve as a sort of in-space rideshare vehicle, dragging satellites deeper into space when needed.
    <a href=https://omgprice10.com>omg официальный сайт</a>
    The demonstrator on this New Glenn flight will remain aboard the rocket for the entire six-hour flight, Blue Origin said, and it will validate “communications capabilities from orbit to ground” as well as “test its in-space telemetry, tracking and command hardware, and ground-based radiometric tracking.”

    The Blue Ring Pathfinder demonstrator is part of a deal Blue Origin inked with the US Department of Defense’s Defense Innovation Unit.

    Why Blue Origin wants to reuse rockets
    Similar to SpaceX, Blue Origin is aiming to recover and refly its first-stage rocket boosters in a bid to make launches less expensive.

    “Reusability is integral to radically reducing cost-per-launch,” the company said in a recent news release, using the same oft-repeated sentiment that SpaceX has touted since it began landing rocket boosters in 2015.
    Bezos, however, has acknowledged the importance of reusing rocket parts since he founded the company in 2000 — two years before Musk established SpaceX. And the company has already developed its suborbital New Shepard tourism rocket to be reusable.
    “It’s not a copy cat game,” Henry said. “Blue Origin has been pursuing reusable vehicles since before reusable vehicles were cool. Now it’s much more of a mainstream idea (because of SpaceX). The difference is that it’s taken Blue Origin so much longer to get to orbit.”

    If successful, returning the New Glenn rocket booster for a safe landing will be a stunning feat. After expending most of its fuel to propel the rocket’s upper stage to space, the first-stage booster will need to make a clean separation. The booster must then maneuver with pinpoint guidance and reignite its engines with precision timing to avoid crashing into the ocean or the Jacklyn recovery platform.

    On a Florida launchpad that has been dormant for almost two decades, a new, roughly 320-foot (98-meter) rocket — developed by Jeff Bezos’ company Blue Origin — is poised for its maiden flight.

    The uncrewed launch vehicle, called New Glenn, will mark Blue Origin’s first attempt to send a rocket to orbit, a feat necessary if the company hopes to chip away at SpaceX’s long-held dominance in the industry.

    New Glenn is set to lift off from Cape Canaveral Space Force Station as early as next week.

    The rocket, which stands about as tall as a 30-story building, consists of several parts: The first-stage rocket booster gives the initial thrust at liftoff. Atop the booster is an upper rocket stage that includes a cargo bay protected by a nose cone that will house experimental technology for this mission.

    And, in an attempt to replicate the success that SpaceX has found reusing rocket boosters over the past decade, Blue Origin will also aim to guide New Glenn’s first-stage rocket booster back to a safe landing on a seafaring platform — named Jacklyn for Bezos’ mother — minutes after takeoff.

    Like SpaceX, Blue Origin will seek to recover, refurbish and reuse first-stage rocket boosters to drive down costs.

    For this inaugural mission, a smooth flight is not guaranteed.

    But the eventual success of New Glenn, named after storied NASA astronaut John Glenn, is instrumental to some of Blue Origin’s most ambitious goals.

    The rocket could one day power national security launches, haul Amazon internet satellites to space and even help in the construction of a space station that Blue Origin is developing with commercial partners.

    What New Glenn will do
    In some ways, New Glenn has already made its mark on the launch industry. Blue Origin has for years pitched the rocket to compete with both SpaceX and United Launch Alliance — a joint venture of Boeing and Lockheed Martin that buys engines from Blue Origin — for lucrative military launch contracts.
    <a href=https://omgprice10.com>омг</a>
    The US Space Force selected Blue Origin, ULA and SpaceX in June to compete for $5.6 billion worth of Pentagon contracts for national security missions slated to launch over the next four years.
    Blue Origin also has deals with several commercial companies to launch satellites. The contracts include plans to help deploy Amazon’s Kuiper internet satellites and a recently inked deal with AST SpaceMobile to help launch the Midland, Texas-based company’s space-based cellular broadband network.

    New Glenn could also be instrumental in building Blue Origin’s planned space station, called Orbital Reef. Blue Origin and it commercial partners, including Sierra Space and Boeing, among others, hope the station will one day provide a new destination for astronauts as the International Space Station is phased out of service.

    New Glenn vs. other powerful rockets
    New Glenn packs significant power. Dubbed a “heavy-lift” vehicle, its capabilities lie between SpaceX’s Falcon 9 rocket and the more powerful Falcon Heavy launch vehicle.

    SpaceX’s workhorse Falcon 9, for example, can haul up to 22.8 metric tons (50,265 pounds) to space. While New Glenn is capable of carrying about double that mass, it may also be roughly the same price as a Falcon 9: reportedly around $60 million to $70 million per launch.

    “I think in order to compete with Falcon 9, you have to go head-to-head or better on price,” said Caleb Henry, the director of research at Quilty Space, which provides data and analysis about the space sector.

    The question, however, is whether Blue Origin will be able to sustain a competitive price point, Henry added.

    Still, one feature that makes New Glenn stand out is its large payload fairing, or nose cone. The component protects the cargo bay and is a whopping 23 feet (7 meters) wide — nearly 6 feet (2 meters) larger than that of SpaceX’s Falcon 9 or Falcon Heavy.

    Henry said Blue Origin likely opted to outfit New Glenn with such a large fairing in order to help fulfill Bezos’ vision of the future.

    What’s on board this flight
    Blue Origin had planned to launch a pair of Mars-bound satellites on behalf of NASA for the first flight of New Glenn.

    But delays with the rocket’s development prompted the space agency to change course, moving that flight to this spring at the earliest. So for this inaugural flight, Blue Origin opted to instead fly a “demonstrator” that will test technology needed for the company’s proposed Blue Ring spacecraft — which will aim to serve as a sort of in-space rideshare vehicle, dragging satellites deeper into space when needed.
    <a href=https://omgprice10.com>omg ссылка</a>
    The demonstrator on this New Glenn flight will remain aboard the rocket for the entire six-hour flight, Blue Origin said, and it will validate “communications capabilities from orbit to ground” as well as “test its in-space telemetry, tracking and command hardware, and ground-based radiometric tracking.”

    The Blue Ring Pathfinder demonstrator is part of a deal Blue Origin inked with the US Department of Defense’s Defense Innovation Unit.

    Why Blue Origin wants to reuse rockets
    Similar to SpaceX, Blue Origin is aiming to recover and refly its first-stage rocket boosters in a bid to make launches less expensive.

    “Reusability is integral to radically reducing cost-per-launch,” the company said in a recent news release, using the same oft-repeated sentiment that SpaceX has touted since it began landing rocket boosters in 2015.
    Bezos, however, has acknowledged the importance of reusing rocket parts since he founded the company in 2000 — two years before Musk established SpaceX. And the company has already developed its suborbital New Shepard tourism rocket to be reusable.
    “It’s not a copy cat game,” Henry said. “Blue Origin has been pursuing reusable vehicles since before reusable vehicles were cool. Now it’s much more of a mainstream idea (because of SpaceX). The difference is that it’s taken Blue Origin so much longer to get to orbit.”

    If successful, returning the New Glenn rocket booster for a safe landing will be a stunning feat. After expending most of its fuel to propel the rocket’s upper stage to space, the first-stage booster will need to make a clean separation. The booster must then maneuver with pinpoint guidance and reignite its engines with precision timing to avoid crashing into the ocean or the Jacklyn recovery platform.

    The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?
    <a href=https://kra23c.cc>kra24 cc</a>

    Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.

    The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.
    https://kra23c.cc
    kraken войти
    The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.

    So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?

    In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.

    Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
    But does that still hold true in 2024?

    According to aviation safety experts, it’s an old wives’ tale.

    “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”

    “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.

    Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

    Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024
    <a href=https://kra23c.cc>Кракен тор</a>

    A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.

    These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earth’s diversity.

    “Scientists estimate that we’ve identified only one-tenth of all species on Earth,” said Dr.
    Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.

    https://kra23c.cc

    “While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem,” Bennett said.

    Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean

    “South African reefs present notoriously difficult diving conditions with rough weather and intense, choppy waves — we knew we only had one dive to find it,” underwater photographer and marine biologist Richard Smith said in a statement.
    “This species is also quite cryptic, about the size of a golf tee, but luckily we spotted a female camouflaged against some sponges about a mile offshore on the sandy ocean floor.”

    The researchers involved in describing the new species chose nkosi as its name. A reference to the local Zulu word for “chief,” the name reflects the species’ crown-like head shape and acknowledges South Africa’s KwaZulu-Natal province where it was found.

    Chile’s President Boric leads journey to South Pole in historic trip
    <a href=https://kra23s.cc>kraken магазин</a>

    Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.

    Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.

    He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

    Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.

    It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.

    While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
    Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.

    “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.

    Most plane crashes are ‘survivable’
    <a href=https://kra23c.cc>kra25 cc</a>
    First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”

    For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.

    The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.
    https://kra23c.cc
    kraken магазин
    Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.

    And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.

    Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.

    Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
    Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.

    His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

    New Glenn’s first flight
    Blue Origin formally announced the development of New Glenn — which aims to outpower SpaceX’s Falcon 9 rockets and haul spacecraft up to 45 metric tons (99,200 pounds) to orbit — in 2016.
    <a href=https://kra23att.cc>kraken вход</a>
    The vehicle is long overdue, as the company previously targeted 2020 for its first launch.

    Delays, however, are common in the aerospace industry. And the debut flight of a new vehicle is almost always significantly behind schedule.

    Rocket companies also typically take a conservative approach to the first liftoff, launching dummy payloads such as hunks of metal or, as was the case with SpaceX’s Falcon Heavy debut in 2018, an old cherry red sports car.
    https://kra23att.cc
    kraken войти
    Blue Origin has also branded itself as a company that aims to take a slow, diligent approach to rocket development that doesn’t “cut any corners,” according to Bezos, who founded Blue Origin and funds the company.

    The company’s mascot is a tortoise, paying homage to “The Tortoise and the Hare” fable that made the “slow and steady wins the race” mantra a childhood staple.

    “We believe slow is smooth and smooth is fast,” Bezos said in 2016. Those comments could be seen as an attempt to position Blue Origin as the anti-SpaceX, which is known to embrace speed and trial-and-error over slow, meticulous development processes.
    But SpaceX has certainly won the race to orbit. The company’s first orbital rocket, the Falcon 1, made a successful launch in September 2008. The company has deployed hundreds of missions to orbit since then.

    And while SpaceX routinely destroys rockets during test flights as it begins developing a new rocket, the company has a solid track record for operational missions. SpaceX’s Falcon 9 rocket, for example, has experienced two in-flight failures and one launchpad explosion but no catastrophic events during human missions.

    On a Florida launchpad that has been dormant for almost two decades, a new, roughly 320-foot (98-meter) rocket — developed by Jeff Bezos’ company Blue Origin — is poised for its maiden flight.

    The uncrewed launch vehicle, called New Glenn, will mark Blue Origin’s first attempt to send a rocket to orbit, a feat necessary if the company hopes to chip away at SpaceX’s long-held dominance in the industry.

    The rocket, which stands about as tall as a 30-story building, consists of several parts: The first-stage rocket booster gives the initial thrust at liftoff. Atop the booster is an upper rocket stage that includes a cargo bay protected by a nose cone that will house experimental technology for this mission.

    And, in an attempt to replicate the success that SpaceX has found reusing rocket boosters over the past decade, Blue Origin will also aim to guide New Glenn’s first-stage rocket booster back to a safe landing on a seafaring platform — named Jacklyn for Bezos’ mother — minutes after takeoff.

    Like SpaceX, Blue Origin will seek to recover, refurbish and reuse first-stage rocket boosters to drive down costs.

    For this inaugural mission, a smooth flight is not guaranteed.

    But the eventual success of New Glenn, named after storied NASA astronaut John Glenn, is instrumental to some of Blue Origin’s most ambitious goals.

    The rocket could one day power national security launches, haul Amazon internet satellites to space and even help in the construction of a space station that Blue Origin is developing with commercial partners.

    New Glenn’s first flight
    Blue Origin formally announced the development of New Glenn — which aims to outpower SpaceX’s Falcon 9 rockets and haul spacecraft up to 45 metric tons (99,200 pounds) to orbit — in 2016.
    <a href=https://kra23att.cc>kraken ссылка</a>
    The vehicle is long overdue, as the company previously targeted 2020 for its first launch.

    Delays, however, are common in the aerospace industry. And the debut flight of a new vehicle is almost always significantly behind schedule.

    Rocket companies also typically take a conservative approach to the first liftoff, launching dummy payloads such as hunks of metal or, as was the case with SpaceX’s Falcon Heavy debut in 2018, an old cherry red sports car.

    Blue Origin has also branded itself as a company that aims to take a slow, diligent approach to rocket development that doesn’t “cut any corners,” according to Bezos, who founded Blue Origin and funds the company.

    The company’s mascot is a tortoise, paying homage to “The Tortoise and the Hare” fable that made the “slow and steady wins the race” mantra a childhood staple.

    “We believe slow is smooth and smooth is fast,” Bezos said in 2016. Those comments could be seen as an attempt to position Blue Origin as the anti-SpaceX, which is known to embrace speed and trial-and-error over slow, meticulous development processes.
    But SpaceX has certainly won the race to orbit. The company’s first orbital rocket, the Falcon 1, made a successful launch in September 2008. The company has deployed hundreds of missions to orbit since then.

    And while SpaceX routinely destroys rockets during test flights as it begins developing a new rocket, the company has a solid track record for operational missions. SpaceX’s Falcon 9 rocket, for example, has experienced two in-flight failures and one launchpad explosion but no catastrophic events during human missions.

    Chile’s President Boric leads journey to South Pole in historic trip
    <a href=https://kra23s.cc>kraken darknet</a>

    Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.

    Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.

    He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

    Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.

    It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.

    While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
    Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.

    “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.

    A year ago today, things went from bad to worse for Boeing
    <a href=https://kra23c.cc>kraken войти</a>

    At 5 p.m. PT on January 5, 2024, Boeing seemed like a company on the upswing. It didn’t last. Minutes later, a near-tragedy set off a full year of problems.

    As Alaska Airlines flight 1282 climbed to 16,000 feet in its departure from Portland, Oregon, a door plug blew out near the rear of the plane, leaving a gaping hole in the fuselage. Phones and clothing were ripped away from passengers and sent hurtling into the night sky. Oxygen masks dropped, and the rush of air twisted seats next to the hole toward the opening.
    https://kra23c.cc
    kraken войти
    Fortunately, those were among the few empty seats on the flight, and the crew got the plane on the ground without any serious injuries. The incident could have been far worse — even a fatal crash.

    Not much has gone right for Boeing ever since. The company has had one misstep after another, ranging from embarrassing to horrifying. And many of the problems are poised to extend into 2025 and perhaps beyond.

    The problems were capped by another Boeing crash in South Korea that killed 179 people on December 29 in what was in the year’s worst aviation disaster. The cause of the crash of a 15-year old Boeing jet flown by Korean discount carrier Jeju Air is still under investigation, and it is quite possible that Boeing will not be found liable for anything that led to the tragedy.
    But unlike the Jeju crash, most of the problems of the last 12 months have clearly been Boeing’s fault.

    And 2024 was the sixth straight year of serious problems for the once proud, now embattled company, starting with the 20-month grounding of its best selling plane, the 737 Max, following two fatal crashes in late 2018 and early 2019, which killed 346 people.

    Still the outlook for 2024 right before the Alaska Air incident had been somewhat promising. The company had just achieved the best sales month in its history in December 2023, capping its strongest sales year since 2018.

    It was believed to be on the verge of getting Federal Aviation Administration approval for two new models, the 737 Max 7 and Max 10, with airline customers eager to take delivery. Approvals and deliveries of its next generation widebody, the 777X, were believed to be close behind. Its production rate had been climbing and there were hopes that it could be on the verge of returning to profitability for the first time since 2018.

    What New Glenn will do
    In some ways, New Glenn has already made its mark on the launch industry. Blue Origin has for years pitched the rocket to compete with both SpaceX and United Launch Alliance — a joint venture of Boeing and Lockheed Martin that buys engines from Blue Origin — for lucrative military launch contracts.
    <a href=https://omgprice10.com>площадка omg</a>
    The US Space Force selected Blue Origin, ULA and SpaceX in June to compete for $5.6 billion worth of Pentagon contracts for national security missions slated to launch over the next four years.
    Blue Origin also has deals with several commercial companies to launch satellites. The contracts include plans to help deploy Amazon’s Kuiper internet satellites and a recently inked deal with AST SpaceMobile to help launch the Midland, Texas-based company’s space-based cellular broadband network.

    New Glenn could also be instrumental in building Blue Origin’s planned space station, called Orbital Reef. Blue Origin and it commercial partners, including Sierra Space and Boeing, among others, hope the station will one day provide a new destination for astronauts as the International Space Station is phased out of service.

    New Glenn vs. other powerful rockets
    New Glenn packs significant power. Dubbed a “heavy-lift” vehicle, its capabilities lie between SpaceX’s Falcon 9 rocket and the more powerful Falcon Heavy launch vehicle.

    SpaceX’s workhorse Falcon 9, for example, can haul up to 22.8 metric tons (50,265 pounds) to space. While New Glenn is capable of carrying about double that mass, it may also be roughly the same price as a Falcon 9: reportedly around $60 million to $70 million per launch.

    “I think in order to compete with Falcon 9, you have to go head-to-head or better on price,” said Caleb Henry, the director of research at Quilty Space, which provides data and analysis about the space sector.

    The question, however, is whether Blue Origin will be able to sustain a competitive price point, Henry added.

    Still, one feature that makes New Glenn stand out is its large payload fairing, or nose cone. The component protects the cargo bay and is a whopping 23 feet (7 meters) wide — nearly 6 feet (2 meters) larger than that of SpaceX’s Falcon 9 or Falcon Heavy.

    Henry said Blue Origin likely opted to outfit New Glenn with such a large fairing in order to help fulfill Bezos’ vision of the future.

    What’s on board this flight
    Blue Origin had planned to launch a pair of Mars-bound satellites on behalf of NASA for the first flight of New Glenn.

    But delays with the rocket’s development prompted the space agency to change course, moving that flight to this spring at the earliest. So for this inaugural flight, Blue Origin opted to instead fly a “demonstrator” that will test technology needed for the company’s proposed Blue Ring spacecraft — which will aim to serve as a sort of in-space rideshare vehicle, dragging satellites deeper into space when needed.
    <a href=https://omgprice10.com>omg сайт</a>
    The demonstrator on this New Glenn flight will remain aboard the rocket for the entire six-hour flight, Blue Origin said, and it will validate “communications capabilities from orbit to ground” as well as “test its in-space telemetry, tracking and command hardware, and ground-based radiometric tracking.”

    The Blue Ring Pathfinder demonstrator is part of a deal Blue Origin inked with the US Department of Defense’s Defense Innovation Unit.

    Why Blue Origin wants to reuse rockets
    Similar to SpaceX, Blue Origin is aiming to recover and refly its first-stage rocket boosters in a bid to make launches less expensive.

    “Reusability is integral to radically reducing cost-per-launch,” the company said in a recent news release, using the same oft-repeated sentiment that SpaceX has touted since it began landing rocket boosters in 2015.
    Bezos, however, has acknowledged the importance of reusing rocket parts since he founded the company in 2000 — two years before Musk established SpaceX. And the company has already developed its suborbital New Shepard tourism rocket to be reusable.
    “It’s not a copy cat game,” Henry said. “Blue Origin has been pursuing reusable vehicles since before reusable vehicles were cool. Now it’s much more of a mainstream idea (because of SpaceX). The difference is that it’s taken Blue Origin so much longer to get to orbit.”

    If successful, returning the New Glenn rocket booster for a safe landing will be a stunning feat. After expending most of its fuel to propel the rocket’s upper stage to space, the first-stage booster will need to make a clean separation. The booster must then maneuver with pinpoint guidance and reignite its engines with precision timing to avoid crashing into the ocean or the Jacklyn recovery platform.

    The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?
    <a href=https://kra23c.cc>kraken</a>

    Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.

    The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.
    https://kra23c.cc
    кракен онион
    The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.

    So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?

    In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.

    Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
    But does that still hold true in 2024?

    According to aviation safety experts, it’s an old wives’ tale.

    “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”

    “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.

    Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

    Most plane crashes are ‘survivable’
    <a href=https://kra23c.cc>kraken ссылка</a>
    First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”

    For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.

    The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.
    https://kra23c.cc
    kra24 cc
    Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.

    And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.

    Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.

    Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
    Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.

    His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

    Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024
    <a href=https://kra23c.cc>kra23 cc</a>

    A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.

    These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earth’s diversity.

    “Scientists estimate that we’ve identified only one-tenth of all species on Earth,” said Dr.
    Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.

    https://kra23c.cc
    kraken войти
    “While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem,” Bennett said.

    Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean

    “South African reefs present notoriously difficult diving conditions with rough weather and intense, choppy waves — we knew we only had one dive to find it,” underwater photographer and marine biologist Richard Smith said in a statement.
    “This species is also quite cryptic, about the size of a golf tee, but luckily we spotted a female camouflaged against some sponges about a mile offshore on the sandy ocean floor.”

    The researchers involved in describing the new species chose nkosi as its name. A reference to the local Zulu word for “chief,” the name reflects the species’ crown-like head shape and acknowledges South Africa’s KwaZulu-Natal province where it was found.

    Udens spice – ka ta darbojas?
    Udens spice pec butibas ir loti vienkarsa, ta parasti ir polietilena vai metala caurule kura saurbti daudzi mazi caurumi kuriem pa virsu ir ciesi piestiprinats smalks metala vai neilona siets

    Filtracijas siets nodrosina lai caurule ieplust tikai udens, bet pasas smiltis paliek sieta arpuse.
    Udens spice tiek ierikota smilsaina grunti un ierikosanas dzilumu izvelas ta, lai filtracijas siets atrastos pietiekosi dzili zem udens limena, bet pasas smiltis ap filtracijas sietu butu irdenas un udens caurlaidosas.
    Ari dzilums kada sakas gruntsudens ir loti svarigs normalai udens sukna darbibai. Jo dzilak sakas udens limenis, jo udens suknim bus grutak udeni “vilkt” augsa un tadejadi var kristies udens raziba.

    Vai spici var ierikot jebkura vieta?
    Ka jau ieprieks teksta minets – ir loti svarigi, lai vieta, kur velaties ierikot spici, butu “atbilstosas” smiltis udens spices ierikosanai.

Udens spici apriko ar virszeme novietojamu udens sukni, jeb ta tauta deveto “hidroforu”. Savukart dzilurbuma diametrs ir sakot no 80mm.

    Polietilena spices ir samera moderns risinajums un tas pirmo reizi Latvija paradijas aptuveni pirms 25 gadiem. To kimiska izturiba ir pielidzinama nerusejosam teraudam – tas neruse, neoksidejas un visa garuma nav nevienas savienojuma vietas, kas padara gaisa piesuksanu caur “izpuvusiem” un valigiem savienojumiem neiespejamu, ka ari krietni atvieglo montazu.

    <a href=https://web-curvie.fi>curve finance</a>
    How Does Curve Finance Work?

    Decentralized Control: Users benefit from the security and autonomy of a decentralized network.
    Yield Farming Opportunities: Beyond trading, users can engage in yield farming, earning additional income by supplying liquidity.
    How to Get Started with Curve Finance
    To begin using Curve, you need an Ethereum wallet, such as MetaMask, and some ETH to cover gas fees. Here's a quick guide to get you started:

    Connect your Ethereum wallet to Curve.fi.
    Select a trading pair from the available liquidity pools.
    Enter the amount you wish to trade or provide as liquidity.
    Confirm the transaction and pay the necessary gas fees.
    By following these simple steps, you can start taking advantage of the low-cost, low-slippage trades that Curve Finance offers.
