Omicron'unlikely'the last COVID-19 Variant, Says WHO

With billions of people still unvaccinated worldwide, plenty of opportunities remain for the COVID-19 virus to spread and generate new variants, according to WHO officials.

“We hope that that doesn't happen. But at the moment, we're not doing enough to prevent that happening in terms of protecting people, and in terms of distributing vaccines in a way that would assist with reducing the emergence of variants,” Dr. Michael Ryan, WHO executive director for health emergencies, said during a press briefing Thursday.

According to Our World in Data, 9.33 billion doses of COVID-19 vaccines have been administered globally. But only 58.8% of the global population has received at least one dose. In low-income countries, only 8.8% of the population has received a vaccine.

When the delta variant emerged as a variant of concern, Ryan recalled, several scientists described it as the “fittest” and “best-adapted virus” they’ve ever seen, and that they “cannot see how this virus could adapt anymore.” But now omicron has been shown to be more transmissible than previous variants, including delta.

“Unfortunately, I think it's very unlikely that omicron will be the last variant that you will hear us discussing. Certainly, the virus continues to evolve,” said Dr. Maria Van Kerkhove, WHO’s technical lead for COVID-19, at the press briefing.

She said important discussions are taking place on how “much more fit” the COVID-19 virus can become in terms of its transmission and transmissibility. And while the current global focus is on omicron because of how fast it is spreading, “Delta continues to be a variant of concern,” she said, noting that there are currently about 30 “sublineages of delta” that WHO is tracking.

“There's a number of factors that are happening. And the question is … what will happen as this virus continues to evolve? And what will those additional mutations mean?” Van Kerkhove said.

"Whole country is playing against 11? "

- by Subham Chatterjee

A faithful cricket fan will always phrase, “Nothing bigger than the game”. On the contrary, a modern cricket fan is faithful to the game for the drama and entertainment it provides, the high dosage of dopamine release just by witnessing the saga of a perfect high-profile game of cricket. From being a gentleman’s game to a pure classic entertainment stage, cricket has evolved for good, keeping the morals of the game intact. However, cricket in its purest red ball form (test matches) continues to amaze that a game which is played over 5 long days can make the audience and players so involved in emotions at the highest level both on and off the field.

One such day of high drama was day 3 of Cape Town test match. Day which began with both teams evenly poised aiming to a series victory turned out to be one of the most fascinating dates in modern cricket history owing to technology and question to the spirit of the game, as the world reacts.

Ashwin to Elgar, 4th ball of the 20th over, the ball drifts in from around the stumps and strikes Elgar, the South African captain, in front of middle and well below the knee roll. That’s what a sport commentary looked like. There was no bat involved and the best part for the Indians, the old man of the match, umpire had already raised the finger up. The nation miles away (some on live tv, some through cricket updates) was already praising the great cricket team, expecting another series win away from home, this time history being in making, all this just for the expectation of the first wicket. Then comes the sense of the Porteas captain, with the time out hand gesture, questioning the decision, making use of technology, the DRS. Now, taking a DRS call is no big deal, but this time around, it was. The ball tracking technology, miscalculated by the Artificial Intelligence, showed the ball would have missed the stumps by an inch. The big screen confirms relying on the ball tracking, this would have gone above the stumps or would it? The umpire had to reverse the decision and quips “that’s impossible”, Indians disgusted. Here, question was about the evaluating the on scene human intelligence (makers of technology) against the Artificial Intelligence, human sense lost and helplessly.

This has happened earlier and no one could device a better mechanism and instance as such of this day is a collateral damage for the greater good of the game. With this thought, the game should have continued but one of the greatest batter of all time is also one the greatest characters on field captaining the Indian side, Virat Kolhi, couldn’t have been more of character than today. Though this time around, it was the bowler himself, Ashwin, tormented by the incident, devised an unique way (again technology), murmuring a few words into the stump mic for the whole world to hear, that he is disappointed and we agree, you were Ash. With the start of this, the Indian camp was pretty excited, pumped up, focused more on letting the world know, that this was wrong and we are at war. Virat, bending over to the stump mic saying, "Focus on your team, while they shine the ball, eh”, this British way of letting the host country know about a mishap in a game, perhaps wasn’t expected or needed. Something which was unnoticed is, this type of act gives the younger mates a confidence to try to shatter the sport spirit, seeing such a lovely cricketer, Mayank, going towards the stump mic with his thoughts was fascinating yet hard to digest. Among all the chatter going on, the deputy of Virat, KL Rahul comes to the picture making a statement which could end friendships, pouring into the mic, “Whole country playing against 11”, no KL, its not the whole country, it’s just a game and tech which went wrong. At the back end, it is an immense pressure for the guys doing the rocket science itself, putting everything together on screen, having the machines build, softwares to run for your game to be played well and calculated well, for your efforts to be shined, there are guys on the chair eating their brains up with loads of codes and caffeine, no KL, its not the whole country, its few hard working office men gearing up for you to be heard and watched while you drive towards the cover. To the defense of KL, Virat and Indian camp, its been an unfair incident and the emotion, commitment for the country which these guys possess can make things heated up around, this is the reason they are one of the best at what they do. Slightest of drift away from protocol which can let them think that they will lose the game for their country can be hurting and the character comes out with emotions overflowing, so I would say, we do understand KL, skipper and lads. But let me take you 15 years back, let’s say, India playing South Africa, imagining we did have DRS into place at that very time itself, but of course we had different boys on the field. Let’s replicate incident but this time, Kumble bowling to Kallis, DRS denied the wicket, Rahul Dravid smiles the way off, the match goes on. The only ask I do have today, what’s the difference between a Dravid and a KL ? May be twitter would react. Whatever it is, I shall be proud of Rahuls, Virats, Sachins, Kumbles or Ashwins and many more to come, as you all are the best for the game for the country.

The KTM 390 Duke and RC 390 are 373.2 cc (22.77 cu in) displacement single-cylinder engine motorcycles assembled by Bajaj Auto, and KTM Asia Motorcycle Manufacturing, Inc. (KAMMI) for the Austrian manufacturer KTM.[1] The bikes were developed under a joint program of Bajaj and KTM engineers, in which the concept was developed in Austria, while everything else, including design and final product development, was done in India by Bajaj.[7] The 390 Duke standard debuted at the 2012 EICMA show in Milan, Italy, and went on sale in India and the Philippines in 2013 and in the US in 2015.[6][8][9] The RC 390 sport bike was presented at EICMA the following year.[10] After the Duke's initial release, KTM CEO Stefan Pierer announced plans to export the 390 Duke to the US for 2014.[11][12] Bajaj said eventually the bike will be sold in 80 countries worldwide.[13]

A sport bike version of the 390 Duke, the KTM RC 390 was presented at the 2013 EICMA motorcycle show in Italy, though most details had been leaked a few weeks earlier.[10][26] The 2014 model year road racing style bike has the same 373 cc engine making a claimed 44 hp (33 kW) @ 9,500 rpm with a claimed weight without fuel of 147 kg (324 lb). With a fuel capacity 10.0 l; 2.20 imp gal (2.64 US gal), the wet weight would be 150 kg (340 lb).[25][27] The frame of the RC is a different single piece trellis frame than the Duke, which KTM says is stiffer than the 390 Duke.[28] The tires are Metzeler 110/70ZR17 front and 150/60ZR17 rear.[28] Where the Duke has a steering head angle of 65° (or 25° rake), the RC's fork has a steeper 66.5° head angle (or 23.5° rake).[24] The 1,340 mm (53 in) wheelbase is 27 mm (1.1 in) shorter than the Duke. The same ByBre disc brakes with ABS, and WP 43 mm front fork and rear shock are used on the RC 390.[27][28]

KTM added a racing version of the RC 390, the RC 390 Cup for use by motorcycle racers ages 13 to 21 in the ADAC Junior Cup, a MotoGP event. The RC 390 Cup has no lights or mirrors, and no ABS to reduce weight, and an upgraded WP suspension, fully adjustable front and rear. The engine is detuned to a 38 hp (28 kW) with a block-off plate, and has an Akrapovič exhaust.[29][30]

Motorcycle Consumer News test results of the RC 390's power were 30.04 kW (40.29 hp) @ 8,600 rpm and 32.92 N⋅m (24.28 ft⋅lb) torque @ 6,800 rpm, with a wet weight of 165.3 kg (364.5 lb)[22] They found a top speed of 167.4 km/h (104.0 mph), with an acceleration from 0 to 1⁄4 mi (0.00 to 0.40 km) in 14.02 seconds at 147.87 km/h (91.88 mph), 0 to 97 km/h (0 to 60 mph) in 5.53 seconds, and braking from 97 to 0 km/h (60 to 0 mph) in 43.1 m (141.3 ft).[22] The tested fuel economy was 4.17 L/100 km; 67.7 mpg‑imp (56.4 mpg‑US).[22]

Cycle World's road tests of the RC 390 also showed a top speed of 167 km/h (104 mph), but faster acceleration 0 to 1⁄4 mi (0.00 to 0.40 km) in 13.67 seconds at 147.87 km/h (91.88 mph), and from 0 to 97 km/h (0 to 60 mph) in 4.6 seconds. Braking performance and fuel economy were not so far off, at 97 to 0 km/h (60 to 0 mph) in 43.1 m (141.3 ft), and 4.1 L/100 km; 70 mpg‑imp (58 mpg‑US).[23] Cycle Worlds's tested power figure was 29.9 kW (40.1 hp) @ 8,600 rpm, and torque was 34.4 N⋅m (25.4 ft⋅lb).[23]

Motorcycle USA measured acceleration from 0-60 mph in 4.9 seconds and 0 to 1⁄4 mi (0.00 to 0.40 km) in 14.21 seconds for 2015 model. Braking distance was measured at 148.2 feet from 60-0 mph with ABS disabled and 151.7 feet without ABS disabled.[31]

KTM revised the RC 390 in 2017 by adding a slipper clutch, adjustable brake levers, ride-by-wire throttle, a larger 320 mm front brake rotor, larger mirrors, and some cosmetic and ergonomic changes.[32]

planning a vacation is much easier than it used to be, thanks in large part to the internet. After all, finding a hotel, flight or dinner reservation is only a quick Google search away. But traveling is still rarely a bargain. If you dig a little deeper, you can find everything from cheap flights to low-cost lodging alternatives. Here are five ways to travel on a budget without sacrificing the quality of your vacation, according to experts.

1. Think about your budget while choosing your destination

Think about your budget while choosing your destination There are many hurdles` travellers face when planning a vacation, but experts say there`s one important detail people need to be more mindful of: their destination.

2. Know where to look when researching cheap flights

Finding a cheap flight when planning a trip is always half the battle. And for those traveling abroad, there is usually no other option than to fly. “That’s a big part of why airfare is so stressful for travellers.

3. Stay for cheap—and even for free

The best way to find housing for cheap is by opting for hotel alternatives like Airbnb, Dominique suggests. Safety is a priority when traveling anywhere, but especially when choosing to rent. Airbnb vets their hosts and allows community reviews, as well as awarding premium properties the title of “super host,” so you can make an informed decision about where you choose to stay.

4. Pack properly

Make sure you bring everything you need so that you don’t have to shop while you’re away (apart from a few souvenirs). No matter where you’re heading, take at least one pair of long jeans, warm hoodie and waterproof jacket for unpredictable weather incidents. For some in-depth advice, check out our ‘Travel like a pro’ guide to packing for every kind of trip.

5. Don’t eat away your cash

Cheap lunches can be bought in a supermarket or even a local fresh food market, rather than in an overpriced cafe or restaurant. Aim to wander around before choosing a place to eat dinner too; if you just pick the first restaurant you see you won’t know if you’re overspending. Drinking beer with every dinner soon adds up – both your wallet and your waistline will thank you if you opt for water instead sometimes. Alternatively, hostels and spare rooms often let you have access to a kitchen if you want to save a little money by cooking for yourself.

Bullying/ Cyber Bullying

When it comes to following your favorite influencer or posting on Instagram, cyberbullying seems far removed from the experience. Unfortunately, more young people than ever before come across others intending to hurt or harass them. Online bullying exists on every platform, and it is important for everyone to recognize the signs when it happens to you, your child, or a friend. This is the first step in finding effective solutions to help stop cyberbullying on Instagram for good.

Instagram Used Mostly by Top Bully Target Age Group

Although video sharing sites like YouTube edged out the competition in most demographics, Instagram is the most popular social media site for young people. Unfortunately, preteens and teenagers are also the main group who suffers from cyberbullying. This transforms the quest to stay in touch with friends and fellow students and to meet new people with similar interests into a minefield of potentially serious problems. Because there are fewer parents using the same platform, they do not always notice the type of behavior that goes on. This makes it more difficult for them to notice the signs of cyberbullying and offer solutions and guidance when necessary.

Signs of Cyberbullying You Should Not Ignore

But considering signs that indicate online bullying behavior, you have to look at things from two different directions. First, the target must recognize when they are being bullied. Second, parents or other responsible people must recognize the signs that their children are experiencing the same bad behavior. Of course, it helps if everyone can so that friends can help and stand up for each other.

Increased Nerves and Anxiety – If you or your child gets anxious about going to school, extracurricular activities, or hanging out with a friend group, it may be a sign of bullying. This can advance into complete avoidance of activities they used to enjoy, which includes spending time on Instagram.

Frustration and Anger – While it is more obvious if you or your child becomes angry during online interactions, these feelings may spill over into formerly pleasant interactions with family or supportive friends. Cyberbullying is invasive and frequently becomes omnipresent in the person's life.

Insomnia, Headaches, and Changes in Appetite – The constant stress and worry of cyberbullying can manifest physically. These types of signs are often caused by the more emotional ones. It can be difficult for young people to recognize why they suddenly cannot sleep and do not want to eat their favorite foods.

Solutions to Bullying on Instagram

Instagram has its own set of tools to help stop cyberbullying and other bad behavior on the platform. The four main suggestions include restricting access to your posts and comments to stop the bullies from leaving their own hurtful responses, blocking people completely, reporting violations of the rules, and automatically hiding comments that contain harmful content.

When these tools are used in conjunction with responsible following and communication practices, it can reduce the chance of experiencing cyberbullying. If you are a parent of a teen who uses the popular Instagram platform, take time to go over the Parent's Guide and familiarize yourself with how it all works. Learn how to support your kids in safe and enjoyable times online with their friends and give them the tools to protect themselves as well.

Electric Eye


Electronic eye has much use in this electronic age. Also known as Magic eye. When electric power was first used to light up streets at night, someone in each street became in charge of turning on the light at nights and turn it back off in the mornings.

Today electric eyes automatically turn on the lights when it becomes dark. It can be used as an automatic guest indicator at the door, if fitted at the bottom of the door entrance. Once it is installed at the door there is no need to install a call bell.

What is it? :

An electric eye is a photodetector used for detecting obstruction of a light beam. The device does not provide an image; only presence of light is detectable

Part Lists-

1) IC 4049

2) LDR

3) Resistance 220 K ohm

4) Buzzer

5) LED

6) 9V Battery with Snap and

7) a Switch.

Circuit Diagram


IC 4049: This electronic eye circuit uses NOT gate from CMOS I.C CD 4049. CD 4049 contains 6 independent NOT gate in one package; we have used here (a) one only. Advantage of using Logic gate is that data can be easily send to other digital interface device ie one can easily fed data to computer using parallel port or for further processing .

2) LDR: To detect the present of an object we have used LDR and a source of light. LDR is a special type of resistance whose value depends on the brightness of the light which is falling on it. It has resistance of about 1 mega ohm when in total darkness, but a resistance of only about 5k ohms when brightness illuminated. It responds to a large part of light spectrum.

3) BUZZER: Sound is produced through buzzer.

4) 9v BATTERY: The output is powered by 9v battery.

5) SWITCH: It is used to allow or disallow current to pass through the circuit.

6) LED: It is Light Emitting Diode which emits light when forward biased.


When NOT gate output goes high (1) the input pin 3 is at lower and at 1/3rd level of the supply voltage. Conversely the output goes low (0) when it is above 1/3rd level. So small change in the voltage of pin-2 is enough to change the level of output (pin-3) from 1 to 0 and 0 to 1.

The output has only two states high and low and can not remain in any intermediate stage. It is powered by a 9V battery for portable use. The circuit is economic in power consumption. Pin 1 is connected to the positive supply and pin 8 is grounded. LDR used in the circuit is a special type of resistance whose value depends on the brightness of the light which is falling on it.

It has resistance of about 1 mega ohm when in total darkness, but a resistance of only about 5k ohms when brightness illuminated. It responds to a large part of light spectrum. We have made a potential divider circuit with LDR and 220 KΩ resistance connected in series. We know that voltage is directly proportional to conductance so more voltage we will get from this divider when LDR is getting light and low voltage in darkness.

This divided voltage is given to input of NOT gate. As soon as LDR gets dark the voltage of input not gate drops 1/3rd of the supply voltage and pin 2 gets high and LED or buzzer which is connected to the output gets activated.


Hence, when the light beam is made to fall on the LDR and is interrupted, the resistance of LDR increases and IC – 4049 will produce a loud sound in the speaker.

A battle royale match consists of up to 50 players parachuting onto an island in search of weapons and equipment to kill the other players. Players are free to choose their starting position and take weapons and supplies to extend their battle life.

When players join a game, they are in a plane which flies over an island. While the plane is flying over the island, the players can jump wherever they want, thus allowing them to choose a strategic place to land away from enemies. After landing, the players must then go looking for weapons and utility items. Medical equipment, medium and large weapons, grenades, and other items featured can be found throughout the island. The ultimate goal of the players is to survive on the island with a maximum of 50 players online; this requires eliminating all opponents the players encounter along the way and ensuring that they are the only survivor remaining. The available safe area of the game's map decreases in size over time, directing the surviving players into tighter areas to force encounters. The last player or team standing wins the round.


Free Fire introduced the Free Fire World Series in 2019, which was won by Corinthians. In 2020, FFWS was replaced by the Free Fire Continental Series due to the COVID-19 pandemic. In February 2021, Garena announced the Free Fire World Series (FFWS) with a $2 million prize pool, which was held in May 2021 in Singapore and was won by Phoenix Force (EVOS Esports TH).
