Walk

If you have ever wondered what the pride of the Spanish Navy is like, this virtual walk puts you in the S-81

by

Although the Spanish Naval History is rich and prolificfor years, Spain built submarines under foreign license. Giving life to one of these vehicles is not an easy task, but at the beginning of this century, something changed and the Navy decided that it was time to have its own model: Class S-80. After years of development, delays and some problems, in November 2023 the S-81 was delivered, aka “Isaac Peral” It is a submarine with some of the latest technology innovations and A “unique” propulsion system (which will work at some point). And, if you have ever wondered what life is like within a submarine or how its operators train, the Navy has published a 3D video in which we can see some of the S-81 rooms. What needs to be done to enjoy the video is to give the ‘play’ and rotate with the mouse, turning the camera to see the first details of the roof and, then, of the interior. The first thing we see is the upper area of the submarine, which in some works has been indicated as the entrance zone to it, but that it is an ‘watchtower’ from which the commander performs the work of approach to port. It is the best point to control the operation and has manual controls and a huge compass. At the bottom of the bow, the submarine entrance hatch can be seen, as well as a series of countermeasures in the foreground. Apart from the torpedoes, the S-81 has electronic and acoustic countermeasures as part of its defense and survival suite. In the offensive weapons, it has torpedoes, missiles and mines. As countermeasures, an acoustic lally system is helped that Imitate the submarine signing To divert enemy torpedoes. It also has the possibility of launch mobile countermeasures, luresand the electronic system allows both the detection of enemies and the disturbance of adversary signals to increase their ability to perform furtive operations. In the final bow we see the hatch through which the crew enters the submarine. In the central hall, a plaque remembers the main characteristics of Isaac Peral, as well as some historical data. On both sides of the hall, we find dependencies for the crew. These are six or three beds cabins and each of the 48 occupants of the submarine has its own bunk. In other submarines, especially in the oldest, there was something called “hot bed”, beds in which the crew slept in shifts. Only the commander has his own cabinless than 3 m². Now, although the crew can be rested by having its own bed, there are bad news: there are only two toilets and three showers for the entire endowment. Under the candle, the highest part of the submarine that is from which the commander controls the entrance to port, is the command platform. This is the brain of the submarine and in the image below we can see operators training in the simulator found on the mainland. Also on the mainland, operators can train with a simulator to learn to keep the ships of the ship through ‘avatars’. It is very widespread, but it is always curious to see how they handle similar systems with Xbox’s command. The truth is that the virtual walk of the Navy is short and would have been great to see some non -confidential units under the optics of that 360º camera. Currently, Isaac Peral will be a few months stopped in port because it will undergo a new maintenance round. As they detail in The confidentialwork will be carried out in Mechanics, electricity, hydraulic, electronics and cooling areas With the intention of calibrating systems such as communications, analyze the operation of the drinking water production system and check the state of missile throwers. The S-81, the unique of the S-80 fleet at the moment, due to a postponement In the afloat of the S-82 Narciso Monturiol until the end of summer, it will be three months stopped in port for this maintenance.

Back to V8 or walk to the electric car. And that says everything about how the industry is

by

“The electric is the future” The words are from Koji Watanabe, head of HRC (Honda Racing Corporation), the division of the Japanese firm in charge of developing the technologies that their teams (and those that hire them) use in the competition. Yeah Formula 1 goes back To the V8 engines, they leave. That is what the Japanese wanted to make clear. Right now, the company does not have an official car inside the championship but supply its engines to Red Bull. In 2026, They will do the same with Aston Martin And they have not ruled out having more customers for the future. But his role in the historic competition can have an expiration date. It all depends on the direction of the sport. The FIA (International Automobile Federation) wants to back the path to the electrification that took formula 1 in 2014. Its bet: Back to Combustion Motors V8. Some teams are for the work but others like Audi or Honda (this as supplier) do not want to hear about the matter. And the dispute threatens to put the sport up. “We didn’t come for this” The first thing we have to know is what is the current situation. The 2026 season will be a year of changes, we will have new chassis in cars and new power units. These power units will finally be maintained as a hybridized turbo. Of course, the weight of the electrification will be greater and the fuel will have to be 100% sustainable from 2026. This regulation should be in force until 2030. The problem is that since the arrival of the V6 Turbo hybridized in 2014 Fans have been complaining that something has died with The end of the V8 and V10. In 2021, despite everything, the regulations of these engines froze to prevent that Honda’s exit will leave Red Bull behind. The background problem is that new engines are giving bad results in simulations. To the point that There is spoils slower than those of Formula 2. The reason is that electrification will become 45% of the total power that a car can deliver (it is currently in 20%) and it is even believed that in a circuit like Monza, the pilot would have to lift the foot at the end of line so as not to end the battery and run out of electrical power for much of what remains circuit. That is especially important next year, since the electric motor will go from delivering a maximum of 120 kW (163 hp) to 350 kW (475 hp). Run without power electric at the end of a line is to be sold for the rest of the return with a very slow car. The way of driving and understanding the car changes radically. “The engine changes completely when braking and curves to produce additional energy, directly feeding on the battery. Therefore, the engine assumes the task of a generator at specific times,” explains Hywel Thomas, responsible for the development of Mercedes engines to Auto Motor Und Sport. That is, at times, the car will act as a series hybrid. That is why some manufacturers have long been moving threads to return the sport to larger engines and reduce the electric weight. He came to talk about returning to the V10whose devastating sound is iconic. Finally, they are pressure to return to the V8. That movement has not liked Honda, who consider that “electrification is a fundamental element To move towards a sustainable future, “making it clear that they do not wait for them if this happens. And he didn’t like Audi either. The company of the four hoops will have a car next year on the grill but the Germans say that ” Hybrid power units It was a key factor “for the company to launch into the pool. They have stressed that “the new regulation was planned for 2026 and beyond”. Returning to V8 is a setback for brand investments just over two years seen. And his message was clear: the V8 “was not for what we came here.” A message that clashes frontally with a good part of the manufacturers. In Motorpasion They collected months ago Ferrari, Ford and Cadillac (Ford will supply Red Bull engines and Cadillac will have its own equipment) They already supported the idea of returning to the V10 engines. And, without committing, Mercedes launched the message in China that “we have an open mind. We are prepared for any engine.” Everything this mess tells us about the industry What is being played with the next big change of regulations is much further than simply, the engines that the cars will use in the competition. It is no accident that Honda and Audi, firms that in their street cars are betting on the electrificationoppose the return of large V8 engines, in the worst stage for them, V10. Nor is it accidental that firms such as Ferrari, Ford and Cadillac support this second scenario. Or that Mercedes does not see him with bad eyes. Already in 2023Christian Horner, Mandamás de Red Bull that recently has been firedhe said that “maybe we return to some V8 or V10 that are totally sustainable. It would be fantastic!” This supposed sustainability goes through the use of 100% synthetic fuels, an idea that would have to go hand in hand if you want to reduce the electrification volume. The key here is that F1 is still seen as a laboratory. The jump to hybridization with the V6 Turbo was designed for manufacturers to explode what they learned with the MGU-H in its street vehicles. However, this component is really expensive and has barely had development out of the competition. With this failure in mind, Ferrari, Ford and Cadillac press to return to the V8 engines. The Italian company aspires to Synthetic fuels are part of its essence in the future. And it also has in mind continue developing large engines combustion since they will allow you to continue selling … Read more

The debate about whether it is better to walk quickly or walk slowly is settled. At least if what we are looking for is our health

by

Walking is an exercise that not only has the advantage of helping us maintain good health, it is also affordable for people with difficulties to exercise in other ways due to circumstances such as age or rhythm. However An old debate persistsSI for extract the benefits of this exercise We can go with a relaxed step or if on the contrary a prescription rhythm is essential. If there are no reasons such as injuries that can be aggravated with sports, physical activity, even in “small doses”, it will always be better than inactivity. That is why the debate about the ideal of walking slowly suits us is easy to settle: walking slowly is better than not walking. Of course, experts tend to agree that, if we have the possibility, better to accelerate the step. Walking can help our health in different ways. Our heart health is, surely, the one that can be appreciated most to wear comfortable footwear and go for a walk, but it is not the only one. Walk has been related to a lower impact of diseases such as diabetes but can also have psychological benefits such as stress reduction or help Improve concentrationespecially when we walk through natural environments. But then what about the Benefits of walking quickly? Again, cardiovascular health is in the center of the debate. A study Recent in highlighting this is the one published in 2024 in the magazine Atherosisclerosis. The study, which had almost 20,000 participants, analyzed their mortality in a period of 9.4 years. The team responsible for the analysis detected an inverse relationship between the rhythm with which they used to walk and the risk of death and suffering from cardiovascular diseases. Studies that relate the rhythm of our gait with the benefits that walk gives our health They are diverse. Some also cover the relationship between speed and cognitive deterioration. Some examples are found in The review published in 2016 In the magazine Ageing Research Reviews. The team responsible for the analysis found a relationship between the speed of the passage when walking and the cognitive deteriorationalthough it was not conclusive about the existence of a direct causal relationship since it could also be cognitive deterioration that makes us walk more slowly. Lose weight Weight is an important risk factor in many diseases. That is why, although thinning does not have to imply that we will be healthier, it can be useful to reduce this risk or as a simple motivation towards healthier habits. Among them, exercise. If our goal is to lose weight, accelerate the step It can also be helpful. Of course, the context can be important, as a group of researchers recently discovered. In Your studypublished in 2024 in the magazine Sports Science & Medicine, They detected that Genetics could be decisive when reducing our weight through this type of exercise. Walking is an affordable and healthy exercise, but science finds more and more evidence that it is best to accelerate the step if we want to make the most of the benefits of our walks. Walking, even at a leisurely rhythm, can help our health, but can also help us take the habit necessary to direct us, little by little, towards a more active life. Step by step.

If “Fast Walk” serves for yourself to lose weight

by

Is it possible to lose weight walking? It is a recurring question and is logical. After all, physical activity facilitates the consumption of calories that our body stores as fat. But it also turns out to be a form of Exercise available to almost everyonesomething important if we take into account that constancy is usually key when we talk about thinning. However, the answer to this question is somewhat more complex than it might seem. Yeah, walk It is a good way to burn calories, and much more: it is also an exercise that provides benefits to our cardiorespiratory and muscular health, and also helps prevent the appearance of diabetes, among other varied effects. That is why it is usually remembered from time to time that, although walking it can be very useful, it may not be the exercise that best suits our plans, and could be seen more as a complement that as the main resource to which we stick to. Now, let’s investigate why. As experts remember, exercise is not always the best strategy if what we are looking for is to reduce our body mass. “For weight loss, The diet seems to be more effective that physical activity “ Donald Hensrud explainsof the Healthy Life program of the Mayo Clinic. Rather, it is usually considered that, in general, the exercise is more effective when maintaining the weight; While if we want to lose weight, control our diet is usually considered a more effective strategy. Of course this does not mean that we should forget this part, even if only for The positive impact That an active life has in our health. The problem is that we tend to Overbear the impact of exercise and physical activity in general in the caloric consumption that our body performs. Alternatively, we can express it in a different way: we tend to underestimate (or directly to ignore) the enormous caloric consumption that our body performs only by being, to keep ourselves alive throughout our day to day. Some estimates place the relative weight of physical exercise Between 10% and 30% of caloric consumption. Imagine a situation in which physical exercise represents 20% of the calorie expenditure that our body performs. This implies that if we folded the exercise we do (100% more activity), we would only increase the caloric consumption of our body by 20%. Combine strategies Leaving weight loss in the hands of a simple strategy is not usually recommended. Constancy is important and use the Exercise as a complement To the diet when we want to lose weight, it can be helpful in various ways. First and perhaps more important, for being a healthy habit to incorporate in our day to day. Secondly, exercise can make changes in the diet more, “distributing” the effort we put to change towards healthier habits. Since constancy is important, a small help never hurts. Third, the exercise, we pointed out before, is a good way to keep us in our weight. The sooner we get the habit, the better. Walking can help us with these three purposes, so it is a perfect complement if we want to lose weight and want to do it in a healthier way. It is a good complement but is it the best? Walking has the advantage of helping us build Routines without great efforts and minimizing the risk of abandonment; But if what we want is to increase the caloric consumption of our body, for example to be able to resort to less strict diets, there are alternatives that perhaps better adapt to our needs. Finally, it is never worth remembering that each body is different, even our own body changes over the years. Formulas and weight losing recipes are not universal, so it is always useful (when not absolutely necessary) consult with experts who can guide us in the process.
