belt

A Ryanair passenger already knows what a seat belt is for. And he discovered him with half his body outside the plane

by

Memmingen is a German city about an hour and a half drive from Munich. In the south of Germany and north of Lake Constance, the city is in a perfect location to receive flights from those traveling to the Bavarian city or Switzerland. Therefore, it is perfect for low-cost airlines like Ryanair. One of its flights originating in Greece, however, has not arrived after a tremendous scare. Outside the plane. It is, according to sources who have offered their testimony to media such as Bloomberg either Reutersthe state in which a passenger on a Ryanair flight departing from Thessaloniki (Greece) to Memmingen (Germany) was found during takeoff. According to the information collected, a man was sucked out of the plane window and half his body was left outside the fuselage. Luckily, the seat belt and the help of the passengers themselves prevented the damage. (he was taken to the hospital with burns) were older. What has happened? They explain the Greek media as the local version of cnn that during a flight to Germany, passengers heard a sound similar to a tire bursting. Immediately afterwards, a passenger found himself with his head and shoulders outside the plane. This was caused because a part of an engine broke and hit the window, breaking it instantly. Immediately, the window itself sucked in the passenger who was traveling right in that seat and the cabin depressurized. The emergency led the pilot to make an emergency landing in the city of Thessaloniki (Greece) where the rest of the travelers were transferred on a new plane to the German city. How did they act? They explain in Flight Radar that the incident occurred when the plane had reached 15,000 feet in altitude in the middle of a takeoff maneuver, they say in The World. That is, the plane at that time exceeded 4,500 meters in altitude. That’s when the accident happened. The plane even had to burn fuel before landing with the cabin depressurized. When the cabin is depressurized, the oxygen inside the aircraft cabin is lost since at the altitude at which it is flown there is little of it. At that moment, as happened in this case, masks fall from the upper area of ​​the seats and passengers must put them on immediately to breathe normally. Why was he fired? In order to keep us alive at this altitude, airplanes hermetically seal their cabins. Inside they simulate similar pressure conditions at 1,500 meters highvery far from the real low pressure outside. This pressure difference prevents, for example, a human being by himself can open the door of an airplane while flying because it has to exert a force that is impossible to achieve. The problem occurs when, as in this case, an external agent breaks a window and the cabin suddenly suffers a sudden change in pressure. In that case, as in that of Aloha Airlines when a man was ejected for not wearing a seat belt. It is the change in pressure itself that causes the air to leave the plane with such force that it drags the objects in its path. And among the objects there may be a person who does not have a seat belt fastened. Investigating. Now, the air authorities will have to study why the window broke and, as everything indicates, it was due to the breakage of a part of the engine. The affected aircraft is a Boeing 737-800 which was manufactured in the United States. Ryanair only uses Boeing aircraft, with a fleet of more than 600 aircraft of this type. The North Macedonian authorities will be the ones to lead the investigations since when the accident happened the plane was already in its territory.

Taking too long to change the timing belt is “a death sentence for the engine”

by

At this point, it is clear that a car that has all its maintenance in order will end up giving us fewer unpleasant surprises during its useful life. That does not mean that it is not susceptible to failures, but if it is in our power to anticipate its maintenance, the better. And in this aspect there are certain critical elements of our vehicle in which it is preferable not to take risks. One of them is the timing belt, which is perhaps one of the most ignored or postponed parts in car maintenance, and which It can ruin your engine from one day to the next. if not changed to the proper frequency. What exactly does it do? The timing belt is a toothed rubber band that synchronizes the movement of the crankshaft and camshaft, the two main shafts of the engine. Thanks to it, the pistons and valves move in coordination, since the valves open and close at the exact moment when the pistons rise and fall. If that timing fails even slightly, the engine loses efficiency. If it breaks completely, the disaster can be total. Why is its breakage so dangerous? When the belt fails in motion, the motor stops dead without warning. In most modern vehicles, what happens next is that the pistons, which continue to move by inertia, violently collide against the valves. “It is a catastrophic event that can spell the death knell for the engine. The dull sound, followed by the absolute silence of the engine, is the beginning of a mechanical and financial nightmare,” they count from the specialized workshop C3 Care Car Center. When the tragedy ends, we can find bent valves, damaged pistons and, in more serious cases, a cracked cylinder head or a fractured camshaft. And of course, the price multiplies many times when it comes to repairing all that piphostio. Mileage. Most manufacturers set a change interval in kilometers, which depending on the model ranges between 60,000 and 240,000 km. But it is not the only number we should pay attention to, since the time of use also counts. From Rodi Motor they claim If there is no maximum date set in the owner’s manual, the usual recommendation is to check the belt every five years even if the kilometer limit has not been reached. The reason is that the rubber on the belt ages even if the car is stopped, and a dry or cracked belt can end up becoming a time bomb for our car. It will depend on the type of vehicle and car distribution system, but to have a universal reference, Juan José Ebenezer, mechanical expert and content creator, advises change it every 100,000 kilometers or every five years, whichever comes first. If we are already talking about oil-soaked belts from the Stellantis group, Ebenezer points out that “with 60,000 km you are already late”, and that it is normal to change them after 50,000 km. Normally, the workshops will change the complete kit, which includes the belt, pulleys, tension rollers, the water pump and all the hardware for installation. But if you prefer to make sure, it is best to tell them to change the complete kit. When to get ahead. There are specific situations in which experts recommend reducing the change interval between 15 and 25% compared to what is indicated by the manufacturer. Alejandro Pais, managing partner of Pais Automoción and Spanish champion of Group N in 2013 explains that “driving in an urban environment usually accelerates the deterioration of the timing belt. If this is your case, calculate between 20% and 25% earlier than recommended by the manufacturer.” In the end, it is not the same for a vehicle to be constantly exposed to cold starts, slowdowns and constant gear changes from exclusive use in the city, to taking it out more or less frequently on the highway. So if you can afford to change the timing belt in advance, the better. The climate also wears it out. High temperatures are another enemy for the belt. Precisely from Volkswagen Canarias, the brand’s official network on the islands, warn In areas with intense heat and suspended dust such as haze, they recommend advancing the visual inspection, even for engines whose official interval reaches 210,000 km. The same logic applies in areas of extreme cold or high humidity. The Midas chain of workshops also recommends advance the maintenance of this component in vehicles that regularly circulate in extreme climates. Better not to risk it. A preventive change of the distribution kit in Spain ranges between 300 and 1,000 euros depending on the vehicle and the workshop. The repair of an engine damaged by a broken belt can start at 1,000 euros and easily reach 6,000, according to they count from Rodi Motor. In more serious cases, when the damage affects the pistons, cylinder head or camshaft, it is possible that the failure is so serious that the entire engine has to be replaced, and then the cost ends up being exorbitant. So do your car a favor and take care of it. In Xataka | 2,000 million euros and 3,000 stations: BYD’s plan so that charging your electric car takes the same time as stopping for gas

They detect if you are wearing your seat belt, if you are on your cell phone or if you make illegal turns

by

Pamplona is going to significantly strengthen its traffic surveillance system starting next June. Although we recently knew the setup of the new section radar of the AP-68which by the way is the second longest in Spain with more than 30 km of distance covered, now the Pamplona City Council will launch four radars with AI capable of hunting down practically any driving violation, from carrying your cell phone in your hand to driving without a seat belt, jumping a red light or changing lanes improperly. Automation. Until now, these types of violations depended on traffic officers. The arrival of these radars automates this surveillance and, above all, it will work as a pilot test in the country, because if they end up giving good results, it is reasonable to think that we will see this technology spreading to other Spanish cities and roads in the coming months. What do they detect?. The new devices incorporate a color camera and a license plate reading system that, combined with AI technology, identify a whole range of illegalities while driving. According to the City Council, they will be able to detect: Use of mobile phone while driving. Drivers without seat belts. Traffic in the opposite direction and prohibited turns. Improper lane changes. Running a red light. Do not respect zebra crossings or stop in yellow-marked areas. Added to all this is a speed control system, with a range that goes from 10 to 320 km/h. The objective according to the City Council is to “monitor compliance with traffic rules, regulate speed and avoid accidents in the city”, as share from Navarra News. What are they like?. The gray cabins are something that has been left behind on these new radars. These are mounted high on staffs, medians or gantries, and withstand temperatures between -30 and 70 degrees without the need for a protective casing. Another important novelty is that they cover several lanes at the same time and bidirectionally (both approaching and receding vehicles) and allow different speed limits to be configured for each lane. Where will they be installed?. Although the idea is that rotate between the eleven cabins that are spread throughout the city, the first planned locations are Army Avenue, Gipuzkoa Avenue next to the Oblatas Bridge, Sadar Street and Paseo de Santa Lucía. The fact that they rotate is precisely designed so that the driver never knows for sure if the cabin in front of him is working or not. Between the lines. Each radar It has cost the City Council 20,000 euros (VAT apart), an investment that the City Council considers justified by the number of infractions that a single device is capable of detecting. In addition, it should be taken into account that a device of this type can fine for behaviors that previously required the presence of an agent or were easier to avoid. So it is quite likely that they will end up recovering the investment based on fines in a short time. Before starting to operate, the radars must pass the approval process of the Spanish Metrology Center, a step that the City Council hopes to resolve in time to activate them during June.

steal materials from the asteroid belt (with a stop at a gas station)

by

We haven’t built yet bases on the Moonbut already there are those who think in that future in which settlements can be built on Mars. If our satellite is a challenge, the red planet is already the pinnacle of complexity. Therefore, although there is still a lot of time for it to be viable, it doesn’t hurt to think about strategies. A good example is the proposal just made by a team of scientists led by aerospace engineer Serena Suriano. His proposal is based on one of the main problems that the space masons: the lack of materials. In the absence of suitable metals for construction there on Mars, they would have to be sought in the vicinity of the red planet. To do this, they propose “looting” the asteroid belt. It’s not that easy. In the asteroid belt There are metallic asteroids that could be mined for necessary metals such as molybdenum. But there is a problem. Traveling to these asteroids to take construction materials to Mars is not like taking the car on a Saturday to go to Ikea. In that case, the biggest handicap is the families that overcrowd the spaces. In the case of asteroids, the main problem is the orbital dance necessary to leave Mars, reach the asteroid and return. Luckily, these scientists consider that the problem could be solved with a couple of pit stops. An (almost) imaginary ship. When making calculations, it is normal to start from the parameters of a ship that actually exists. For this reason, these scientists have made simulations with an imaginary ship that is not the same, but looks like quite to the SpaceX Starship. The most powerful imaginable today. The ship in question weighs 120 tons, can carry a payload of 115 tons and hold up to 1,100 tons of fuel. This would mean a delta-v of 6.4 km/s. And what is that? The delta-v is a measure of the amount of effort necessary to carry out an orbital maneuver. In simpler terms, it is the change in speed that can be achieved by burning all the fuel in a ship. In this case it would be 6.4 km/s. The problem is that to reach the metallic asteroids that could be mined to build on Mars, taking into account the necessary orbital spins, a delta-v of 10 to 12.8 km/s would be needed. It can be solved. These scientists have designed a plan that includes two pit stops. The first would be on the metallic asteroid itself. Once the materials have been extracted, on the way back we would have to stop at a type C asteroid. These contain volatiles such as water and hydrocarbons, which would facilitate a process known as production on site of propellant. In other words, the type C asteroid would be used as a gas station, using its resources as propellant to continue the trip. If these stops are made, the necessary metals could be obtained with a delta-v of 6.4 km/s. The imaginary ship looks like Starship, but it is not the same 22 pairs. In total, there are 22 pairs of metallic asteroids and C-type asteroids in a 20-year window starting in 2040. This means that, from that moment, when it is assumed that trips to Mars and the construction of bases could already be viable, there would be more than 20 mine and gas station options to bring metals to the red planet. In total, 200 tons of metal could be obtained in that period. It may not seem like much if we consider that it is little more than the payload for a single trip. But fuel needs to be optimized. The loading process on site of propellant is carried out at a rate of 2 kg per day. To fill the tank it would take about 1,500 years. Logically, that is not viable, so you have to go with the tank half full and, therefore, adjust the payload. Why 20 years? For the trip to take place, it is necessary that the orbits of Mars and the asteroids are correctly aligned. It’s as if the road to Ikea only opens once every few years. Therefore, many trips could not be made. Building an entire base would take a lot of time, but it’s something you have to take on. A solution. If chemical propulsion is changed to solar propulsion or nuclearit would be much easier to extract metals from asteroids and, possibly, the deadlines would be shorter. However, these scientists have chosen to make their calculations with the only viable technology today. Maybe in the future the trip will be a little shorter than all this. Of course, building a base will continue to be a very, very long process. Many generations of humans would retire looking at those works.

Walking cats with belt is in fashion. We have asked an expert in feline behavior and is clear about what he thinks

by

If you have Instagram or Tiktok and you like cats, I bet an arm to which videos have come out of Cats that leave the house tied with strap and harness. Some even go on a trip around the world, explore forests, jump, run and They even swimas if they were dogs. How is it possible? Is it advisable to walk the cat? To solve these and other doubts we have spoken with Paula VanascoFeline therapist and president of the association Rescues Borges Blanques. The phenomenon of adventurous cats It began to popularize in the 2010 on Instagram. One of the first was Vladimirthat traveled with its owners in a motorhome Throughout the United States. Also Skattya Maine Coon who was traveling on a sailboat with its owner, who was completely deaf and leaned on the cat to know when ships approached or sent him messages. A search on Tiktok returns to hundreds of results. “Cat harness”, “Adventure Cat”, “Cat Leash Training” … Today, any of these searches in Tiktok or Instagram returns us hundreds of results. Walking to the cat is fashionablebut it is not easy. If not, many of the reels that appear to us would not be tutorials and advice to accustom the cat. And if there is something that has tried to know is that, unlike dogs, cats They don’t like anything to atten. Understanding the nature of cats Paula is part of the team of Feline therapy And in your day to day Treat cats with behavioral problemssome of them caused precisely by these walks. Its positioning is clear: it is not a good idea to put a belt to a cat. “Cats are hypersensitive animals. For them a harness is stressful, so when you put it on the first time, many are thrown to the ground.” In addition, he adds that “to make it safe, it has to go very tight, which still makes it more annoying for the animal.” You have to understand that the nature of cats differs a lot from the dog. They are territorial animals and They feel safe within their territoryit doesn’t matter if that territory is the countryside or a flat in the city. When they leave their comfort zone, they always do it very little by little: “The cat needs to explore the territory at its rhythm, not that you take it wherever you want.” Instead, walking to a dog is more natural because its nature is to move in herd. They are social animals And security is provided by your pack, so when we walk them they feel safe. Image: Amparo Babyloni, Xataka Surely you have seen cats rubbing against the corners of furniture or other objects. It is the way they have of Create a safe space. When they explore, cats are rubbing at different points where They leave pheromones that serve as olfactory references. “This is how they explore the territory feeling safe. If there is any scare they go back, then they leave again … and so on until they have it controlled.” “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it.” Nor should we forget that, although cats are predators of small animals, they are also prey to other larger ones. “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it,” says Paula. It is not that the cats we see in the Instagram videos are all stressed, Some enjoy those outings, But according to Paula “they are the exception. They are cats that have learned that their environment is that and also have a very balanced character.” Using them since childhood is key because “cats do not develop fear until they have 5 or 6 months,” but insists that this is not a guarantee that it will enjoy it and should never be forced. What we don’t see on Instagram If it is outside its territory and scares, The cat instinct is running and getting safebut what happens if we have it tied? Two things can happen: “Let the harness escape or attack you.” In This video You can see perfectly how the cat tries to flee and when not getting it, he ends up biting its owner. Is what is known as redirected aggressivenessan episode in which the cat has a very violent response, in this case for a clear cause: try to flee and not be able to. If the cat tries to flee being tied, two things can happen: “That the harness escapes or that attacks you” The other scenario is to get rid of the harness and run away (the most common, because we already know that Cats are liquid). Being in a environment“It has no visual or olfactory references and there are not a few cases of cats that end up being lost.” If it is also in the city, the risk that a car is hit or attack a dog is very high. There are people who opt for Take the cat inside a backpack type carrier and walk it in this way. Here it is much more difficult for the cat to flee, but Paula does not recommend it either: “I had a case of a cat that took him inside a backpack. The cat did not show the stress at the time, but when he got home he became aggressive. They were very frustrated to be locked up.” Another problem is that many people who get their cats abroad do not know how to understand The language of cats. “That a cat is still does not mean that it is calm.” In other words, it is not necessary to go crazy like that of the video so that it is assuming stress.
