Think of masks as the newest trendy accessory that can save your life -- and the lives of those you love.To get more news about nonmedical dust proof mask, you can visit tnkme.com official website.

But instead of what pattern, logo or slogan you display, choose your mask based on its effectiveness against the deadly coronavirus in the environment you are in.
Guidelines on how to help you make that choice should be out by midspring, according to Jonathan Szalajda, deputy director at the National Personal Protective Technology Laboratory, which is part of the National Institute for Occupational Safety and Health at the US Centers for Disease Control and Prevention.
Working closely with government agencies, industry stakeholders and ASTM International, an international technical standards organization, the standards will apply to filter efficiency, sizing and fit, cleaning and recommended period of use or reuse.Made from fibers woven with an electrical charge that can trap errant particles -- like a sock that sticks to your pants in the dryer -- studies have shown N95-type respirators are currently at the top of the line when it comes to filtering large and small particles. Masks in this category are also known as "filtering facepiece respirators" or "disposable respirators."
What would happen if every American wore an N95-type mask for four weeks in risky settings like being indoors?
"It would stop the epidemic," Dr. Abraar Karan, an internal medicine physician at Brigham and Women's Hospital and Harvard Medical School, told CNN Chief Medical Correspondent Dr. Sanjay Gupta.
N95 respirators come in many sizes to accommodate various face shapes. When fitted to the wearer's face and worn properly, N95-type masks can trap 95% of particles around 0.3 microns, studies have shown. SARS CoV-2 can be as small as 0.1 micron in diameter -- that's about 4 millionths of an inch.
While it may seem that N95 filters would miss the tiny Covid particles, that's not so. Most bits of virus exit the lungs encased inside larger respiratory droplets, typically much bigger than 0.3 microns.Even those that become aerosolized are easily captured. Due to a natural phenomenon called Brownian motion, such minute particles don't travel in straight lines. Instead they bounce around in a zigzag fashion and are easily caught in the N95's electrostatic filter.
While some experts are calling for a nationwide rollout of N95 masks, such masks are currently reserved for health care professionals on the front lines of caring for Covid-19 patients. That's partly due to a shortage of such masks, which are designed to be worn once and discarded, but also due to the training needed to fit and wear the mask properly.
"In a health care setting, there's an advantage because there's a degree of sophisticated training to inform people how to properly wear respirators which doesn't exist in a public setting," NPPTL's Szalajda said.
According to the CDC, a few other respirators also meet or exceed the 95% efficacy level: the N99, N100, R95, R99, R100, P95, P99 and P100 masks. Some of these devices -- which can look like gas masks -- have received an emergency use authorization and can be used in nonsurgical settings during shortages of N95 masks.

A sign is still posted on the front door of the Wolfeboro Food Co-op that reads, “Face masks required.” Until recently, another sign had hung directly below it, explaining how the New Hampshire market was following federal policy.To get more news about Quality Medical Mask, you can visit tnkme.com official website.

Erin Perkins, manager of the shop, removed that second sign on 14 May — the day after the US Centers for Disease Control and Prevention (CDC) announced that fully vaccinated individuals, in most situations, no longer need to wear a mask. “We weren’t expecting that,” says Perkins. “It puts us in a precarious position. We were not about to start asking people if they are vaccinated or not.”

New Hampshire was the last state in New England to start mandating mask wearing in public to reduce the spread of the coronavirus SARS-CoV-2. And on 16 April, it became the first in the region to lift that mandate, joining several other states around the country that were loosening their pandemic-related restrictions. Cities and businesses in New Hampshire could still set their own policies, and Perkins wasn’t comfortable changing things right away. Even after the CDC announced its latest guidelines — just two weeks after communicating that vaccinated people should continue to mask up indoors — Perkins wasn’t personally comfortable with unmasked people in her shop. She also knows that several customers have immune systems that are compromised, and emerging research suggests that people in this group are still at risk even after vaccination1.Until we feel better about the state of things — until the numbers make a little bit more sense to us, we have decided to wait,” she says, even if that means dealing with testy customers.

Anne Hoen, an epidemiologist at Dartmouth College in nearby Hanover, can understand Perkins’s caution. She says that both the state and federal moves were probably a little too early. Hoen works in New Hampshire but lives just across the border in Vermont, where a state-wide indoor mask mandate remained in force until mid-May, despite Vermont having a lower rate of hospitalizations than practically anywhere else in the country. In the wake of the CDC’s announcement, Vermont Governor Phil Scott relaxed the mandate for fully vaccinated individuals.

The weakening policies are out of step with those of many other countries. Germany strengthened its mask requirements at the end of April, for example. It was facing a slowdown in vaccination rates and a surge in cases. Spain tightened its requirements at the end of March.

The evidence is clear that masks cut down on COVID-19 deaths, but nearly a year and a half into the pandemic and with vaccination coverage climbing in many places, public-health scientists and officials are still struggling to get people — particularly unvaccinated people — to wear masks at appropriate times. Average mask use across the United States has been declining since mid-February. Meanwhile, infection rates in some places have increased. A patchwork of policies and mixed messages from both politicians and public-health officials has resulted in confusion, consternation and a mess of data to interpret. “We’re all over the map,” says Monica Gandhi, an infectious-disease physician at the University of California, San Francisco. “That’s been the problem this entire pandemic. We’ve been making it up as we go along.”
It wasn’t until late April, for example, that the US government finally distinguished between indoor and outdoor mask use in its recommendations, even though the science had been clear for months that the risk of transmission was much lower outdoors2. And now, after the CDC released its latest revision, agency director Rochelle Walensky noted that it could change its mask guidance yet again. Hoen and other epidemiologists warn that it is very difficult to reinstate a rule after it has been revoked.

Mask use will continue for this pandemic, and it’s likely to become a common response to future outbreaks. So researchers are trying to get a handle on what the science says about how to encourage people to wear them. As the COVID-19 pandemic enters a new phase, scientists around the world are accessing the accumulated data and asking what makes some policies more effective than others, and probing when and how they need to change.

Gandhi is among those who emphasize that mask messaging should evolve in light of rising vaccination rates. Officials should begin relaxing restrictions to give people hope and to motivate vaccination, she says. But changes need to be made carefully.

The Philippine Stock Exchange (PSE) wants to be the platform for trading crypto assets when the countrys regulators issue long-awaited rules governing the practice, according to a report from CNN Philippines.To get more news about ALGO, you can visit wikibit.com official website.
  PSE President and CEO Ramon Monzon told CNN that management first discussed the idea of setting up a domestic crypto exchange two weeks ago. The PSE has both the trading infrastructure and investor protection safeguards that Monzon said are necessary to trade cryptocurrencies.
  Monzon told CNN that mounting interest in cryptocurrencies means the Philippines cannot ignore them anymore. The PSE is currently awaiting guidelines from the Philippine Securities and Exchange Commission (SEC), which began seeking comments from banks, investors, and the public in 2019 on whether the country should begin building a domestic crypto exchange.
  The country‘s government has historically been friendly toward digital assets. The Philippine Central Bank, though it has been outspoken about not considering the development of a central bank digital currency (CBDC) anytime soon, has licensed over a dozen crypto exchanges to operate in the country. And many Filipinos have become interested in crypto as a way to make money in the country’s struggling economy, with play-to-earn crypto mobile games like Axie Infinity becoming a popular way to earn extra income.
  Monzon told CNN that he believes the volatility of cryptocurrencies is what makes them attractive, which is why trading should happen under the watch of the PSE.

The financial specialist and professor at the New York University – Aswath Damodaran – criticized bitcoin in a recent speech. In his opinion, the primary digital asset “failed miserably” and did not prove itself as a good currency.To get more news about KNC, you can visit wikibit.com official website.
  Gold and BTC Are Not The Same
  The prominent Indian professor – Aswath Damodaran – shared his point of view on bitcoin in the most recent episode of Moneycontrol Masterclass. He asserted that the largest cryptocurrency has failed to classify as a good currency because people disregard it as a payment method for daily and household purchases:
  “A good currency, in my view, is one that [is] used to buy coffee, buy your house, buy a car, and on that count, bitcoin has failed, and not just failed, its failed miserably.”
  Damodaran, also known as “the Dean of Valuation,” believes that crypto enthusiasts ignore bitcoins disadvantages only because they have made a lot of money from it.
  Speaking about the correlation between gold and the digital asset, the Indian opined that the yellow metal is the true store of value because it holds its price during financial catastrophes. He reminded that this is not the case with bitcoin, whose volatile nature makes it a highly risky investment tool:
  “Gold‘s biggest claim to fame is that when stocks collapse, gold holds its value. If I use the same test on bitcoin and I look at 2020, bitcoin didn’t behave like a collectible. It behaved like a very risky stock. Put simply, if I add bitcoin to a portfolio of stocks, Im just adding something that makes my portfolio even more volatile.”
  Did BTC Really Disappoint That Much?
  And while many critics questioned bitcoin‘s merit due to its volatile fiat currency price, MicroStrategy’s CEO – Michael Saylor – asserted that it is a better hedge than gold during these uncertain economic times of increasing inflation. He went further, stating that it outperforms the yellow metal by 50 times:
  “I think in the past 12 months, we have all been waiting for inflation, and I think we are seeing it now. I think investors are seeing that bitcoin is up by 330% and gold is up 7% in that period. So, bitcoin is outperforming gold as an inflation hedge by a factor of 50.”
  Known as one of the biggest BTC maximalists, Saylor highlighted the cryptocurrencys merit not only over gold but over all other investment instruments.

Taproot is on its way. The long-awaited Bitcoin (BTC) upgrade has been confirmed, after it passed the minimum threshold of 90% miner approval in mid-June, meaning that it will be implemented in November.To get more news about ENJ, you can visit wikibit.com official website.
  While the core features of Taproot — increased privacy and enhanced wallet scripting — are fairly well-known, what will the upgrade's impact be on Bitcoin in a wider sense? Will it attract more adoption, take users away from privacy coins, or even incur the wrath of regulators?
  The answers to these questions are fairly mixed, according to a range of Bitcoin developers. Because while Taproots features might attract greater use of Bitcoin, it may also take a while before applications and Bitcoin-based services make full use of them, with protocols having to be built on top of Bitcoin before cost-saving and privacy features have a significant impact.
  What Taproot does for Bitcoin
  As a recap, here are the three main benefits Taproot will bring to Bitcoin:
  Reduced fees for multisig/complex transactions: Taproot will significantly reduce the data needed for processing complex transactions, such as those involving multiple signatures or time-locking. This is great for anyone who needs greater security.
  Increased privacy: in combination with Schnorr signatures, Taproot will let users mix transactions made by complex (e.g. multisig or time-locking) wallets with those using only single signatures. It will therefore let anyone concerned about revealing their use of multisig to hide such use.
  Enhanced wallet functionality: Taproot will let developers set more complex conditions for wallets. For example, it will let developers create multisig wallets which start off by requiring 3 out of 5 signatures to confirm transactions, but which can degrade over a set period of time to require only 2 out of 5 signatures. This is ideal if you anticipate the possibility of losing any of your private keys.
  These are the core features offered by Taproot. And pretty much every developer Cryptonews.com spoke with agreed that such features will be widely used, but not immediately.
  “I expect the features enabled by Taproot will be used very widely once downstream applications integrate them, as they will help the applications provide valuable features, procure competitive advantage and lower costs,” said one Bitcoin developer, who asked to remain anonymous.
  Other developers agree that we‘ll need to wait for applications, wallets and protocols to implement Taproot before its beneficial effects will fully make themselves known. For developer and BTC wallet service BTCPay Server founder Nicolas Dorier, it’s unlikely that adoption for Taproot will be as wide as it was for SegWit, particularly for users requiring only single-signature payments.
  “It will be widely used for other protocols built on top of Bitcoin (like Lightning). On-chain, Taproot makes the use of these protocols indistinguishable from other protocols. Multisig benefits from such kinds of enhancement will follow for sure, but will current multisig wallets move to Taproot?,” he asked, adding that the answer to this question is not clear yet.
  “Taking advantage of the privacy upside requires some more complex protocol (musig2) to be able to work,” he said, noting that it might not be worth the trouble for current multisig wallets.
  For Bitcoin author/educator/developer Jimmy Song, multisig wallets will gradually integrate Taproot, but again not immediately.
  “Not much at first, but much more over time. There is demand for good backup solutions, so yes, I think wallets will be integrating them,” he told Cryptonews.com.

The arrival of interoperable solutions will be an opportunity for a positive shift in the publics perception of blockchain.To get more news about USDC, you can visit wikibit.com official website.
  Crypto and blockchain enthusiasts take pride in belonging to a community that is working on the future of financial systems. Yet, the community is innately fragmented thanks to multiple blockchains working independently of each other. The dream of mass adoption of blockchain and decentralized finance faces a major hurdle: a lack of interoperability.
  Meanwhile, decentralized applications (DApps) — the fruits of decentralization — are being held up. DApp developers face difficulties while transacting between different blockchain networks, and the reason behind this is they are stuck in the Ethereum ecosystem. Despite having the best infrastructure, Ethereum is losing its foothold.
  Ethereums pursuit of single-network blockchain dominance
  As per a DApp market report, around 59% of all DApps run on the Ethereum blockchain. The growth of decentralized finance on Ethereum notwithstanding, many developers and users are unhappy with the network.
  Growing transaction charges are an outright bane for developers and users alike. Likewise, the Ethereum network is also prone to clogging. Even six years after launch, Ethereums transaction speed languishes around 15 transactions per second (TPS). The combination of the above factors derails the efforts of developers by pummelling the feasibility of their projects.
  Also, the highly-anticipated Ethereum 2.0 upgrade fails to address the scalability issues. Eth2s complete implementation may be more than a year away. When you consider associated efforts like proof-of-stake migration and security upgrades, measures to tackle the scalability issue seem to be nowhere near the priority list.
  Part of the vision for Eth2 is “to make applications faster and cheaper to use.” With reality furthering itself away from that vision, however, the crypto-finance community is looking for alternatives.
  These alternatives are built on collaboration rather than competition. The potential driver of decentralized finance growth is enhanced interoperability.
  Interoperability and the hunt for interoperability solutions
  Touted as a solution for applying decentralized finance outside of the Ethereum blockchain, interoperability furthers the idea of decentralization. By facilitating seamless communication between different blockchain networks, interoperability is where the future lies.
  With interoperability, the traditional mentality of “I use blockchain B as it is better than blockchain A” undergoes a paradigmatic shift. We are moving toward a culture where blockchains A and B collaborate and are used in unison for a specific purpose.
  For better context, consider this: Without interoperability, the vast majority of DeFi protocols would lack the largest blockchain network and cryptocurrency, Bitcoin (BTC). However, with the help of blockchain bridges, it is now possible to transfer one‘s BTC holdings to the Ethereum network in the form of wrapped tokens such as Wrapped Bitcoin (WBTC), which has tokenized around 1% of Bitcoin’s supply on Ethereum. These ERC-20-compatible wrapped tokens offer faster Bitcoin transactions and enable users to employ Bitcoin on DeFi protocols such as Aave to lend and borrow assets — or perform other DeFi activities.
  It‘s also because of blockchain interoperability that users have the freedom to transact ERC-20 tokens on the Binance Smart Chain, dodging Ethereum’s spiking gas fees and executing transactions almost instantly. The arrival of interoperable solutions shall act as a window for multiple DeFi products and applications.
  Many developers, particularly those in high-volume sectors such as gaming, are now looking to layer two solutions to solve their problems. However, many of these solutions have been slow to deliver while developers waver over options like Plasma state channels technology. Rollups are the hot new workaround, bundling transactions for higher throughput.
  However, the fact is that many Ethereum layer two protocols leave DApps constrained to the Ethereum ecosystem. Without the chance to interoperate, developers and users cant tap into any value emerging from other platforms.
  Moving on, how can we attain seamless interoperability while bypassing the challenges faced by existing layer two infrastructure?
  Trustless bridges: The Holy Grail for blockchain interoperability?
  As the name implies, blockchain bridges are built to span blockchains and facilitate communication. This technology solves the issue of interoperating between two different protocols. Using trustless bridges, users can leverage the benefits of both blockchains.
  Generally, these bridges are governed by the “burn-and-mint” approach. According to this, tokens do not leave their respective blockchains during the transaction. The token is burned or locked in its blockchain, while its equivalent is minted or created on another blockchain. This method ensures a constant token supply and reduces volatility.
  There are two types of blockchain bridges: federated and trustless. The former is a private and more centralized project that requires certain criteria to be met before the bridge can be used. On the flip side, trustless bridges operate in a decentralized environment: Similar to Bitcoin and Ether (ETH) miners, trustless bridge validators receive incentives to maintain the bridges. Here, trustless bridges work on mathematical truths and are devoid of any human errors or corruption.

The current carrying capacity of the wire and cable refers to the amount of current carried by the line conductor. During the use of the wire and cable, the maximum current required by the load must be less than the long-term allowable current carrying capacity of the wire in the air. So, what are the specific factors that affect the current carrying capacity of wires and cables? Guangdong Rifeng Cable Co. Ltd


1. Core area
Under normal circumstances, the core area (cross-sectional area of ​​the wire) is proportional to the current-carrying capacity, that is, the larger the core area, the greater the current-carrying capacity.
2. Conductor material
The current carrying capacity of different materials under the same conditions: silver>copper>aluminum. If copper wire is used to replace aluminum wire, the current carrying capacity can be increased by 20%-30% under the same specifications.
3. Insulation material
The temperature resistance of commonly used insulating materials is polyvinyl chloride: 70°C, cross-linked polyethylene: 90°C, and polyolefin material: 150°C. The use of insulating materials with good high temperature resistance and thermal conductivity can increase the current carrying capacity of the cable.
4. Contact resistance
The smaller the resistance coefficient of the cable, the larger the allowable current-carrying capacity. Therefore, soldering, soldering, and crimping can be considered when bonding wire ends to reduce contact resistance.
5. Cable spacing
When multiple wires are laid in parallel, the proximity effect and skin effect will be formed, so that the electric charge is concentrated in the part of the wire cross section and the allowable current carrying capacity of the wire is reduced. In addition, applying multiple strips will cause heat accumulation, which will also reduce the current-carrying capacity.
6. Ambient temperature
The greater the thermal resistance around the cable, the worse the heat dissipation and the smaller the current carrying capacity.
