In Córdoba we have many things. Have The only mosque in the world that is not oriented to Mecca. In fact, Córdoba is the only city on the planet with Four World Heritage Assets of UNESCO. The first person to fly It was also from Córdoba, as they were You see, Seneca either Julio Romero de Torrres. We have a gastronomy that has no rival (I will die in this hill), a street thermometer that opens news in August and, since this weekend, a traffic light with artificial intelligence. That traffic light knows things. This peculiar device is located on Avenida del Airport, just in front of the Health Center. The location was agreed with different groups and makes sense: in the area many services are offered to people with reduced mobility, such as the aforementioned health center, the headquarters of the San Rafael de Alzheimer’s association, an orthopedics and, of course, is on an avenue capable of absorbing traffic. Because no, this traffic light has no goal Optimize trafficbut to facilitate mobility to people who use crutches, wheelchairs or carry carts. The traffic light in front of the Health Center in Córdoba | Image: Xataka “A source of pride”. That is this traffic light for Bernardo Jordano, delegate of inclusion and accessibility of the City of Córdoba. Although According to Jordano“without wanting to sound pretentious, we have no knowledge of something equal to this”, the reality is that there have been similar pilot projects in other countries, Like Germany without going any further. The Cordoba project, in fact, reminds the German Ki4ped. Because? Because this traffic light uses cameras and an artificial intelligence system to detect people with reduced mobility and give way before and for a longer time. That is, it takes less to get green and lasts more seconds. It is not a strictly new traffic light, but has been updated with a larger staff and two bidirectional cameras. According to Jordano: “For almost a year, in a learning phase, we have taught the machine to detect users with reduced mobility, so the device is already trained to see users in wheelchair, with walker and even baby chairs. When that happens, the traffic light modifies the normal cycle and gives more time to that type of pedestrian. “ The system feeds on two cameras like this. Each look at an address | Image: Xataka The hard traffic light, by default, 30 seconds. If it detects a person who meets these conditions, time increases to 35 seconds. It is exactly the same purpose as the German pilot project Ki4ped, only that it used a lidar and the Cordoba uses cameras. The project is already implemented and now it will be the users who have to validate if five seconds are enough or “if they need a little more time.” Interestingly, this traffic light does not have a incorporated second accountant, something that would help the user realize that the system, indeed, works. According to Antonio Galindo, president of the Cordoba Association of Multiple Sclerosis, “a great problem of mobility is the times, and there is already a solution.” Those affected by multiple sclerosis suffer from limiting fatigue, that is, they tire a lot even if they use support such as a wheelchair or a walker. The pressure they can feel when crossing a pedestrian step and seeing that they run out of time to cross can be huge. Image | Xataka Training. According to Pedro Vaca, responsible for the maintenance of traffic facilities in the city, the process began a year ago. To do this, they recorded videos in the Fepamic area (which is quite far from the location of the traffic light) “because it was where we had pedestrian crossings and where there was more influx of wheelchairs and walkers.” The recordings took six months and about 700 videos were achieved “that have served us as the basis to analyze and take the models of the three types of vehicles that are currently being detected.” How does it work? The company behind the artificial intelligence algorithm itself is the Cordoba Interlight. As explained to Xataka Manuel Barrios and Jerónimo Jiménez, technical director and CEO of the company, respectively, the system consists of two cameras with artificial intelligence that look at the two senses of the pedestrian passage and an algorithm of own development. The key to the algorithm, they explain from the company, is that it has self -learning. “The algorithm sees when wheelchair users pass, with canes, with baby walkers or carts, which are the four patterns that discriminates, and adding them to the model so that the algorithm improves itself.” On the left, the traffic light with AI | Image: Xataka These processes have several layers and from the company affirm that the system meets the LOPD. “We are in Europe, this is a very serious issue. Our strong is to apply artificial intelligence to something very particular respecting European guidelines, as it should be.” However, from Xataka we have been able to verify that nowhere close to the traffic light it is warned that there are cameras recording. The model detects the user in a preventive way, is anticipated, as it approaches the passage of pedestrians. If the person approaches a critical area, that is, he prepares to cross, the system sends a signal to the traffic light and indicates that it is open for a longer time. To do this, emulate the software the mechanism to press the button to ask that the traffic light opens, although this traffic light does not have said button. All this happens in 200 milliseconds, a rather low latency, and in different conditions: day, night, with rain, cloudy … The latency of the detection system is just 200 seconds The success rate is 90%, but “weekly it is increasing its capabilities. What we have seen is that the effectiveness is quite high, but when we put a frame that we have not detected, we add it … Read more

A new material with the help of Ruthenium wants to change the rules of green hydrogen

by

Renewables have postulated as the Future of Energyboth particular and in entire countries. They are also the present, with examples such as Sorpasso in countries like Spain and others like Uruguay pulling practically only renewables for months. Within those renewables, the development of methods to produce green hydrogen more efficiently is key. And a team of South Korean researchers They believe Having found the key to approaching that new era of green hydrogen: a new material that promises to revolutionize energy production. Colors. Hydrogen is extremely abundant in the universe, but it has a problem: finding it without being combined with other elements is very difficult. It is an element that has a great ease to combine and, to use it as a source of energy, it is necessary to separate it from those other elements. There are several ways to do itbut if we use renewables as an energy source, we can achieve what is known as ‘green hydrogen’. Catalysts. By means of the electrolysis technique, water hydrogen is separated. For hydrogen to be “green” it is necessary that, in that process, we use solar, wind or hydroelectric energy as a source of energy. Also an element that works as a catalyst, elements that accelerate the necessary chemical reactions to separate the hydrogen from the element to which it is linked. The better the catalyst, the faster the reaction occurs, making the process more efficient in time and resources. The problem is that they are usually expensive due to the presence of precious metals, which makes them little accessible and also have a high environmental impact because these metals are extracted from mining, some as part of Rare earth. No precious metals. That is why there are researchers experiencing with catalysts based on transition metals, non -metallic materials (such as graphene) and others that combine elements such as ruthenium, silicon and tungsten. Precisely, Ruthenium is the main ingredient of the new catalyst they are developing in the Group of Metrology of Emerging Materials of the Institute for Research and Science Science of Korea (or Kriss). The team had a catalyst with a molybdenum dioxide structure with nickel-molybdenum . They were clear that they had to investigate the Moo₂-Ni₄mo route as a catalyst, but not in their current state. Example of the electrolysis process to separate oxygen hydrogen Ruthenium shield. That’s when they decided to take the eye on Ruthenium. They introduced a small amount of this element into the structure of Moo₂-Ni₄mo and realized that, with river nanpoarticles of a size below the three nanometers, a thin layer was formed on the surface of the catalysts. Impact. This works as a shield that prevents degradation, improving durability. How much? According to its evaluations, the new catalyst presents a durability four times greater and is capable of lasting six times more in activity if compared to other existing commercial materials. All this without using rare or precious metals in the process. In addition, they combined the new catalyst with a photovoltaic system that uses Sovskita-Silicio solar cellsachieving conversion efficiency of 22.8% of solar to hydrogen. It is a promising result because it shows that this new catalyst is not only resistant and accessible, but efficient. Pocket. The problem of green hydrogen is that, although it is a fundamental element in our Way to Discarbonizationhis first appraisal has not been too encouraging. In December last year the first Iberian index of the price of renewable hydrogen was launched. Baptized as mibgas, The starting price was € 148.36/MWh. To compare, that of natural gas was about € 45.83/MWh. It was not something encouraging, but something completely normal due to the current production cost of hydrogen. Not only to talk about the infrastructure (with the entire system not only of electrolysis, but also of solar panels to feed the process), as well as the cost of the catalysts. That is why, cheaper catalysts that maintain high efficiency pave the way to the extraction of green hydrogen at a more restrained price. Looking at the sea. From the KRISS they are confident with their achievements because that new catalyst has not only marked with a green point the sections of price, efficiency and durability, but is exceeding expectations. Sun Hwa Park is the team’s principal researcher and has commented that these catalysts are also demonstrating high stability in saline water. “Currently, green hydrogen production requires purified water, but the use of real seawater could substantially reduce the costs associated with desalination. We plan to continue our research in this area. ” It will be the next challenge of a team that is not alone in this, since there are other teams and universities that have been proposed Exactly the same: use new transition compounds and metals to reduce precious metal dependence on catalysts. Now, everything indicates that it is something that will take time to establish and, without going any further, there we have the price of solar energy and how much it has dropped When technology has been popular.

The Plan of Spain for leading green hydrogen has been faced with an unexpected problem: Zamora

by

The countdown for the passage of the H2Med corridor It is underway. The one that will be the first clean hydrogen corridor of the European Union will be underway by 2030, but, as in any project, it is not exempt from controversy, since the section that goes from Zamora (Spain) to Celorico da Beira ( Portugal) has aroused a conflict. The controversy. The Duero Hydrographic Confederation (CHD) He has authorized A INARI SOLAR SL The extraction of 117,000 cubic meters per year of groundwater of the Natural Reserve of Las Lagunas de Villafáfila. The initiative will supply a 40MW green hydrogen production plant. Located in Moreruela Granja (Zamora), the Unión del Pueblo Leonese party (UPL) has warned about environmental impact of this project in a protected wetland. For this reason, divisions between neighbors, environmentalists and politicians have not been expected, between those who support it and who fear its consequences. In addition, the controversy has reached the Unesco Through the Ramsar agreement, an international treaty for the protection of wetlands. The decarbonization process. Spain It has different green hydrogen pointsbeing Zamora one of the most strategic points for the installation of infrastructure for the production of this renewable. However, producing green hydrogen requires large amounts of water, an increasingly scarce resource in Spain. In fact, 82.5% of the water It is used for agricultureand the country Face an accelerated desertification process. For this reason, the choice of the Villafáfila aquifer as a source of supply has generated outrage. The process. The CHD granted The concession in January after a period of public information of a month that, according to the agency, was closed without allegations or reports against. The Confederation argues that the extracted water will be minimal compared to the total of the aquifer, representing only 0.1% of the available resources. In addition, the concession will be 25 years, allowing a maximum flow of 3.8 l/Sy will capture by means of a 70 -meter depth survey. However, environmentalists in action, among other organizations, He has questioned These data because they point out the devastating impact on the wetland. In addition, he has denounced the lack of transparency in the process and has pointed out that authorization has been done on a place where restrictions for agricultural irrigation. From the town. Social discomfort has grown rapidly and already circulates In Change.orgunder the motto: “#Salvemosvillafáfila! A natural treasure in danger of disappearance.” The initiative accumulates more than 7,000 signatures, denouncing that water extraction will endanger an ecosystem necessary for bird migration and the local economy. From the political sphere, and as we have pointed out above, UPL has resorted to authorization before the Junta de Castilla y León and has taken the case to Ramsar agreementwith the aim of opening the door to a possible international review. In favor. From the Popular Party, the president of the Diputación de Zamora, Javier Faúndez, He has shown Your support for green hydrogen, but Reject the choice of aquifer as a water source. In addition, he argues that there are more viable alternatives, such as the Esla River or a nearby reservoir. While from the Ministry for Ecological Transition and Demographic Challenge, on which the CHD depends, has defended the concession ensuring that the regulated procedure has been followed and that the impact will be insignificant. However, the authorization must still pass the filter of the Junta de Castilla y León, which has promised a rigorous evaluation of environmental effects. Forecasts The conflict continues to climb and everything indicates that there will be citizen mobilizations in the coming weeks. The Junta de Castilla y León has the last word, so if the authorization continues, the debate could reach European instances. All this would test the compatibility between the EU climatic ambitions and the conservation of the environment.

Green gelatin, the new viral and delicious dessert that everyone is talking about for its anti-aging benefits

by

Eating well is not only a pleasure, but also synonymous with health when we choose foods designed to consciously nourish our body: the three garnishes that Vanesa Lorenzo chooses for dinner, for example, they are digestive allies for a time when feeling light is the highest priority; As an anti-inflammatory insurance we recommend 9 raw materials famous for their anti-bloating benefits; and Kim Kardashian and Isabelle Junot inspired us with its detox juice which they take first thing in the day. Today we are going to talk to you about another recipe that has gone viral in record time not only because it is a delicious and low calorie dessert with which to snack, have breakfast or finish each meal with a sweet detail, but also because they ensure that helps increase collagen productionthe fountain of youth of our skin, hair and bones. To learn more about the green jelly that everyone talks about on the internet We have spoken with experts who have not only detailed its benefits, but have also revealed other rejuvenating recipes and whether we can really alter the amount of collagen we produce through diet. © Getty Images The benefits of green gelatin The most viral dessert of the moment is prepared with a nopal, spinach and lemon and Amil López, nutritionist and doctor in pharmacy, convinces us that there is no shortage of reasons to succeed: “Green gelatin is rich in collagen, a protein essential for skin elasticity and firmness.” Although in his case he recommends another variety of the recipe based on green tea, spirulina and matcha to provide antioxidants: “They fight free radicals, delaying the signs of aging. Consuming it regularly can contribute to brighter and healthier skin.” Dr. Conchita Vidales, aesthetic doctor and coordinator of the nutrition unit at DEMYA Martín del Yerro I Amselem, highlights its protein content, collagen amino acids and vitamins: “Especially the C in spinach, because it helps us increase the amount of collagen available in the body, which is necessary for the proper maintenance of structures. Although among all the variants of the recipe, the Mira+Cueto medical team warns that there are some that are richer in collagen than others: “Perhaps the best known is the one we find in the supermarket, but it may not be the best option, as it has flavorings and sugars.so a healthy way to consume it is to prepare it at home with the most natural ingredients possible.” In addition, the Madrid clinic lists its benefits: Healthy when we prepare it at home as it has low calorie content and higher protein content. Elasticity, hydration and firmness of the skin and its connective tissue. It promotes the health of bones, tendons and joints, as it is a source of calcium, magnesium, phosphorus, silicon and other minerals that help regenerate and strengthen the musculoskeletal system. Strengthens nails and hair. It contains an amino acid called glycine that stimulates the acid in the stomach necessary for digestion and assimilation of nutrients. Strengthens blood vessels, improving circulation and promoting cardiovascular health. © romeestrijd Collagen and diet Our experts are adamant that what we eat has a direct impact on our appearance. Dr. Conchita Vidales recommends vitamin C, essential for collagen production; “but above all we can increase the collagen that our body needs through foods such as chicken, beef, pork, blue and white fish, eggs and gelatin either beef, chicken or pork bone broths and cartilaginous structures such as pig’s trotters, pig’s mask, tripe or ox’s tail. Amil López tells us that although the body produces collagen naturally, the process deteriorates with age. Therefore, apart from the diet, he speaks wonders about nutricosmetics: “Include a specialized supplement such as Collagen LPGwhich contains highly bioavailable peptides, can enhance results by acting from the inside. It is the result of a patented combination of marine-derived collagen and elastin peptides in proportions identical to those of the skin. After just 28 days, a reduction in the number of deep wrinkles is observed and after three months the skin is strengthened.” © Getty Images From Mira+Cueto they also recommend the rejuvenating soup that women love celebrities: “A food with great capacity for collagen stimulation is bone broth (beef or chicken) cooked over low heat for hours, which is rich in natural collagen that when cooked breaks down into gelatin, amino acids such as glycine, proline and lysine, essential for the production of collagen in the body. Wellaging nutrition If we approach the issue of designing a diet for the skin from a global approach and not just focused on collagen production, DEMYA nutritionist Martín del Yerro I Amselem points out balance as the key to success: “Proteins, for the contribution of amino acids that support structures such as skin, bones and muscles as well; slow-absorbing carbohydrates (quinoa, legumes, fruits and vegetables); unsaturated fats (omega 3 and 6); and maintain proper hydration through water, infusions, chicken broths and a good supply of vitamins and antioxidants, including vitamin C, E, D and A.” To make our task easier, Amil López suggests a “beautiful skin effect” menu rich in proteins, antioxidants and healthy fats: Breakfast: red fruit smoothie with spinach and chia seeds and walnuts. Snack: green gelatin. Lunch: quinoa salad with salmon and avocado. Dinner: bone broth with vegetables. French omelet. © maralafontan Foods that dull and damage the skin After knowing what we should do, the Mira+Cueto medical team points out what we should not do and they begin with salt for its liquid retaining effect. “It is also known that dairy consumption can cause acne and other skin inflammations. Rosacea and acne problems have been documented associated with the consumption of even skimmed milk.” Finally, they tell us that “we must reduce the consumption of sugars and processed foods as much as possible”, a change that improves hydration levels, texture, wrinkles and even the appearance of inflammatory diseases. Dr. Conchita Vidales adds “alcohol and ultra-processed foods because they are the worst for our skin and promote … Read more
