But many Covid-19 tests can give results within hours without sending the sample to a lab, and most of these tests use an approach called microfluidics. What are microfluidics? A microfluidics system is any device that handles small amounts of liquid. Fluid moves through channels thinner than a hair, and tiny valves can turn the flow on and off. These channels are made of materials such as glass, polymers, paper or gel. One of the ways to move liquids is to use a mechanical pump; another way is to use the surface charge of certain materials; and one more way is to use so called capillary action – commonly known as wick. One thing is clear, every nook and cranny of the human body is microfluidic. We could not be born or function without complex blood capillaries that carry food, oxygen, and signaling molecules to every cell. Like microelectronics, size is a key factor in microfluids. As components get smaller, devices can rely on the exotic properties of liquids on a small scale, can work faster, more efficiently, and have cheaper manufacturing costs. The microfluidics revolution has been quietly shouldering microelectronics technology. Another major benefit of microfluidic devices is that they require only a very small amount of liquid and can therefore be very small in size. NASA has been considering using microfluidic analyzers for their long Mars missions. The analysis of precious liquids – such as human blood – also benefits from the ability to use small samples. Example: A glucose meter is a super liquid instrument that requires only one drop of blood to measure a diabetic’s blood sugar. Chances are you have been using microfluidics quite often in your life. Inkjet printers shoot out tiny droplets of ink. The 3D printer extrudes the molten polymer through a microfluidic nozzle. A nebulizer for asthma patients will spray out tiny droplets of medicine. The pregnancy test relies on the flow of urine in a microfluidic strip of paper. In scientific research, microfluids can direct drugs, nutrients or any liquid to very specific parts of an organism to more accurately simulate biological processes. The future of microfluidics Microfluidics will be key to bringing medicine into a new, fast-paced, affordable era. Wearables that measure substances in sweat to track fitness progress and implantable devices that help deliver cancer drugs locally to a patient’s tumor are some of the next frontiers in microbiology. biomedical liquid. Researchers are developing complex, fascinating microfluidic systems called organs on a chip that aim to simulate different aspects of human physiology. In laboratories around the world, teams are developing tumor-on-chip platforms to test more effective cancer drugs. These patient-representative chips will allow scientists to test new treatments in a way that doesn’t entail the cost, suffering, and ethical issues associated with animal or human testing. Imagine going to the doctor, taking a biopsy sample and, in less than a week, using the scientists’ microfluidic device, the doctor can figure out which drug is most effective to remove the mass. your u. While that is still in the future, what we do know is that microfluidic will be an integral part of the future.

Not in the purpose of use but in the material that makes it. The entire body of this toilet paper is made of gold, the shape is not much different from ordinary toilet paper, rolled into a tube, but making such a precious metal as gold is inherently laborious. strength. This toilet paper roll is divided into three layers in total, lined up side by side, all made of very tight and molten gold. In the eyes of the average person, gold is a very expensive metal, often used to create fine jewelry, but creating and using toilet paper costs the same as a mansion or a sports car. Luxury sports are truly ‘cool’, and of course this is a unique, most expensive toilet paper roll in the world that is unmatched. The use of gold as a raw material is inherently incredible, but it pales in comparison to the wealthiest Middle Eastern Arab monarchs in the world. Because they often use gold to create various items from gold cars, gold toilets and now gold toilet paper for daily use, making the whole world go crazy with “jealousy”. However, with the price of a toilet paper roll of nearly 30 billion VND, it is definitely not suitable for daily use, but it can be used, it is also very difficult, so it will only become a collector’s item. Middle Eastern ‘kings’.

The origin of the Darvaza crater remains controversial, but the most widely accepted theory involves a Soviet expedition to explore for gas. (Photo: Internet) According to the Daily Mail, in 1971, Soviet experts drilled and dug the area and reached a large cave filled with natural gas. Unfortunately, however, the ground beneath the part being dug collapsed, creating a huge hole with a diameter of 70 meters. Concerned that the pit would lead to a toxic gas leak, the experts decided to burn it. And as a result, the amount of gas below is so abundant, that the fire in the pit keeps burning forever. It has been burning for 50 years now. (Photo: Internet) George Kourounis, a Canadian explorer, became the first known person to venture down into the pit’s interior. Footage of his expedition was first broadcast on National Geographic, which partially funded the trip. The aim is to collect soil samples from the bottom of the pit, and try to determine if life can survive in such a harsh environment. (Photo: Internet) Kourounis shared: “ The story behind how the hole was born is still a mystery, and there is no place like it on Earth. It is very unique. ” Despite being the most popular tourist attraction in Turkmenistan, the Darvaza fire pit has always kept its pristine and quiet appearance because this place is so remote and far away from traffic. The number of tourists visiting this country has been small, and it is not easy to get here. (Photo: Internet) If you go by private car, it takes nearly 4 hours to get there. For those who travel alone, they have to take a public bus, then find a car rental or walk 7-8 km to Darvaza which takes at least 6-7 hours. The red-orange fire pan appears more and more brilliant and fanciful against the background of the sky, which gradually changes from pink to purple, to blue, to black. Visitors here are eager to capture every moment of nature. A giant fire well that shines brighter and brighter in the middle of the vast, dark desert, a lonely but fierce beauty that makes anyone who sees it overwhelmed. (Photo: Internet) (Photo: Internet) Coming here the previous afternoon and leaving the next morning, visitors will admire all the wonderful moments at Hell’s Gate: an enchanting purple sunset, a magical moonlit night and a radiant morning. pristine.

The ceramic pot has a special shape with a high and pointed lid, which helps the food to be cooked by steam, without losing nutrients. This pot is quite common in Moroccan cuisine. “Chawan” is the name of a traditional cup used to drink tea in the “land of the rising sun” Japan. The characteristic of “chawan” cups is that they make the user feel comfortable when drinking, holding, holding and can keep the temperature for a long time. is a type of traditional bowl for making and drinking tea. Chawan has many different shapes, sizes, materials and is quite sophisticatedly crafted. Dolsot is the name for the stone bowl, which can keep food amazingly hot. This bowl is mainly used to prepare mixed rice dishes, raw beef and eggs can be cooked as soon as they are placed in the rice bowl. If you place this special bowl directly on the table without any protection, you may damage the table. Bamboo steamer is popular in Asian countries, but in the West it still brings a lot of fun and curiosity. These steamers have the advantage of being environmentally friendly, do not burn food and you can enjoy the food right after it has been steamed without having to use too many dishes. This pear-shaped cup is widely used in Azerbaijan and Turkey. It has the interesting advantage of keeping hot drinks underneath without helping the user to burn their hands. Raclette is the name of the famous Swiss cheese dish and is also the special name of a special tool that helps cheese to melt under a large pan of food. One of the famous specialties of Spain is Paella rice, which is made from roasted rice and seafood. The pan is not deep but has a large diameter that can serve the whole family. Italy, the country of pasta, is very popular with these noodle machines. Even this machine is cherished and cherished as an inheritance gift from generation to generation.

The process of making glass blowing through many stages. The first is the selection of raw materials, the glass fragments must ensure no stains and be classified according to different blue and white colors. The broken or worn glass pieces are then recycled by furnace and heated in a molten state. Glass can be machined in many ways such as blowing, pressing, pulling, rolling … but the popular machining method that has been applied for hundreds of years is still “blowing”. You must first “whip” molten glass into the end of a long iron tube, then put your mouth on the other end of the tube and blow. In this way, the glass at the other end bulges out. While blowing, the worker must shape and make the product of the appropriate thickness. In the glass forming steps, the blowing technique is the most important, the craftsman said. The worker must regulate his breath so that it is rhythmic and suitable for each product. Therefore, in addition to their health, skilled craftsmen also have to have breath-holding tricks to fit the desired shape. As the oldest person still working as a glassblower in Giap Long village (Thong Nhat commune), Mr. Ho Van Ginger shared: “With the naked eye, the worker has to estimate the maturity of glass to start blowing. At this time, the operation must be fast and continuous, without a break even for a second, because the glass out of the fire quickly cools, if stopped, it will be distorted immediately. ” According to him, in addition to perseverance, the blower needs to be careful when constantly exposed to fire above 1,200 degrees C, not only that, it also needs meticulousness and creativity to just skillfully adjust the breath. slightly, hands are rhythmic to create straight, patterned curves. Each glass factory has its own know-how in the brewing process. The appropriate incubation time and temperature for each product will determine the brightness and durability of the product. Finished product after the oven meets the requirements with transparent white, sharp and delicate lines. With the designs that require a lot of quantity, the finished product must reach the correct rate, all “hundred as one”. The process of making glass products consists of many stages that require meticulousness and ingenuity of the craftsman. Photo: Diem Quynh The first and most popular blown glass product was Philatop syringe, followed by other products such as oil bulb, thermos cap, drinking cup, seedlings. In the beginning, when there were no sources of raw materials, electricity and motors, the craftsman created and utilized other materials and craft tools to the glassblowing profession. Used fluorescent bulbs are used to take advantage of, wash off the lime inside and melt to blow. The forge furnace is used as a glass blowing bell, the gas pedal is below, the upper uses 6 wicks rolled together, continuously pumped kerosene to burn the fire up to a thousand degrees. The worker uses two concrete pieces to close the fire to a slot, the stronger the wind pedal, the bigger the fire, the heat is used for different types of glass such as alkaline, neutral, and resistant glass. high heat. When the glass was first put in the fire, it will turn green and burn to the point where it will turn white. The main glass products of the craft village today are test tubes, bulbs, bottles. Photo: Diem Quynh During the blowing process, workers must focus on observing when the glass is ripe and blowing, rotating hands to shape, in addition, it is necessary to twist, pull, and weld techniques. Different weak blow strength results in different products as well as the thickness of the glass. After finishing blowing, to avoid sudden shrinkage or breakage when storing boiling water (for glasses), it is necessary to incubate it for a few hours. After that, all products are covered with newspaper and carefully lined with straw so that the product is not broken or broken. In addition to household products, Thong Nhat craftsmen also blow shapes of animals such as deer, ba ba, fish, pine trees, 12 zodiacs, wind chimes … very sophisticated. At a time when the craft was developed, the animals were filled with colored water inside, which was favored by the market. At present, Giap Long, Hoang Xa and Thuong Giap villages of Thong Nhat commune still retain their jobs. However, each village has only a few households following the industrial way. In the years 1980 – 1990, glassblowing was an important job of the commune, making a mark with the famous Thong Nhat Glass Cooperative near and far.

The Nigambodh Ghat Crematorium in New Delhi, India. Photo: Getty Images According to CNN (USA), a crematorium in the state of Uttar Pradesh is in a similar situation, with the number of bodies brought to cremation fivefold in recent weeks, as the 2nd wave of COVID-19s. booming in India. “We had to work day and night, at 100% capacity, to cremate bodies in time,” said Kamlesh Sailor, chairman of the Kurukshetra Cremation Facility Executive Trust in Surat City, Gujarat State. west India, said. Data difference As India’s health system is on the brink of collapse, several major cities have recorded far greater numbers of bodies sent to cremation and burial compared to deaths due to COVID-19. official father. On April 18, India recorded a record 273,810 cases of COVID-19 and 1,619 deaths. As of April 20, the total number of COVID-19 cases of this country has exceeded 15.5 million, second only to the US. A front line employee cremates a man who died of COVID-19 at a crematorium in the Indian suburbs of Mumbai. Photo: Reuters Reliable data is central to the government’s pandemic response, experts say. Without reliable data collection, the preparation of hospital beds and medical essentials will be extremely difficult. But Indian government officials say the disparity in mortality data could be caused by many factors, including an overly prudent body handling process. Many bodies are still cremated according to COVID-19, even if they are only 0.1% likely to be positive for the SARS-CoV-2 virus, a health official said. “Many hospitalized patients were in critical condition and died before testing. There are cases where patients died before admission, we don’t know if they have COVID-19 or not”, the official said to be anonymous. Ms. Bhramar Mukherjee, Professor of Epidemiology and Biological Statistics at the University of Michigan, said there are many areas in India where accurate data cannot be collected. “Things are messed up. It feels like no one understands this situation, it’s annoying,” said Ms. Mukherjee. The crematorium is operating at full capacity The crematorium of patients COVID-19 in Surat broke out. Photo: AFP In Surat, the second largest city in the state of Gujarat, the crematorium Kurukshetra and Umra processed more than 100 bodies a day according to COVID-19 regulations last week. The number of bodies cremated is much higher than the daily death toll, according to the city’s official record of about 25 people. Mr. Prashant Kabrawala, representative of Narayan Trust, Ashwinikumar crematorial company, refused to provide the number of bodies cremated in accordance with COVID-19 regulations. However, he says the number has tripled in recent weeks. “I have never seen so many cremated bodies in the last years, even during the outbreak of the plague in 1994 and the flood of 2006,” Kabrawala said. A Government spokesperson for India in Gujarat declined to respond to a request for comment. India is not the only country that is skeptical of the SARS-CoV-2 virus statistical data. But documents and staff testimonies at cremations show that the disparity in officially reported deaths in India is much higher than in other countries. Professor Mukherjee’s study on the first wave of epidemics in India showed that the number of viral infections was 11 times more than officially reported, which is similar to research in other countries. Besides, the number of deaths in this country is actually 2-5 times higher than the reported data, far exceeding the global average.

Death from COVID-19 is recognized by the government. These figures do not take into account other burial facilities, or cases where COVID-19 victims were buried according to Muslim custom – the community makes up a quarter of Lucknow’s population. The number of bodies cremated under COVID-19 regulations has increased fivefold in recent weeks, said Azad, manager of the Baikunthdham facility. “We work day and night. The crematorium is constantly on fire, but many bodies are still waiting in line,” Azad said. People pray before burying the COVID-19 victims at a cemetery in New Delhi. Photo: Reuters Cremations are many times greater than the COVID-19 mortality data also recorded in many other parts of India. In just four days of April, two cremation facilities in Bhopal – the capital of Madhya Pradesh state, central India – recorded 187 bodies cremated according to COVID-19. Meanwhile, the number of deaths from COVID-19 officially announced by the authorities was only 5. Last week, the local Sandesh newspaper reported 63 bodies were taken to a hospital for patients with COVID-19 in the city of Ahmedabad. But that same day, the city authorities counted only 20 people who died from COVID-19. The Lancet Medical Journal says less than a quarter of all deaths in India are medically confirmed, especially in rural areas. This means that the actual COVID-19 mortality in many other Indian states may not be counted. “Most of the deaths are not reported so it is impossible to calculate,” said Ms. Mukherjee.

According to the video content, the special dessert served in the hotpot restaurant costs 26 yuan ($ 3.95), including four “lipstick”. This is also a highlight attracting more diners to a hot pot restaurant in Chengdu to enjoy. Many people, especially women, are extremely interested in the restaurant’s new business idea, because the edible lipsticks are not only beautiful in color, but also look exactly like the real lipstick used for makeup. point. Lipsticks are served as desserts at a hotpot restaurant in Chengdu, China. (Photo: Global Times) “I wonder if there are lip colors I have not tried or not?”, A humorous person commented. Meanwhile, the hotpot restaurant owners in Chengdu have been working hard to come up with ways to attract customers, as more and more restaurants have opened for business in recent times. Before that, in March, a hot pot restaurant in China’s Shaanxi province had a rather special way of attracting customers, which was to hire a group of 6-pack boys topless and wear aprons as waiters. In fact, all male waiters at this restaurant are models. Not only bring food to the table for customers, the 6 pack boys also wholeheartedly serve to cook at the table or pick up the dishes for customers. In addition to working for the restaurant, the apron models are also willing to take souvenir photos or videos with customers. The attentiveness of the male waiters is that they are willing to wear napkins for customers and sit at the same table to eat and chatter. According to local media, since the hotpot restaurant has recruited new customers, most of the customers who come to enjoy the food here are women every day.

Accordingly, the lipstick cake is made from chocolate. They are meticulously decorated, shaped like a real lipstick. In addition, this dish also has a rather mysterious name “Goddess of Makeover”. Thanks to this special dessert, hot pot restaurant in Chengdu attracts many diners. Many people, especially women, are extremely interested in the restaurant’s new business idea. Lipsticks are served at hot pot restaurants in China. Not only impressed by its eye-catching appearance, but also attractive by its special taste. Ms. Zhu – the restaurant’s chef – said: “First, we melt the pure chocolate, mix it, pour it into the mold and then refrigerate for about 1 hour. Each lipstick has a different color and taste. There are even lipstick on the outside covered with chocolate, inside is filled with banana or strawberry “. “I came to the hotpot just because I wanted to enjoy a dessert exactly like a lipstick. I have already tasted it and I love it. I wonder if there are any lip colors I have not tried yet?”, A guest funny comment. To enjoy the dessert, customers pay 26 yuan for a set of 4 “lipstick”. Before that, a hotpot restaurant in Shaanxi (China) attracted customers by hiring a cast of 6-pack male models, topless and wearing aprons as waiters. Not only bring food to the table for customers, these guys also serve the cooking at the table. In addition to working for the restaurant, the apron models are also willing to take souvenir photos or video with customers.

Earth 300 is expected to launch in 2025. In particular, there are 22 laboratories on this ship. Scheduled to launch in 2025, this ship can accommodate 450 people. The Earth 300 ship was built by Aaron Olivera. This researcher expressed a desire to bring an inspiring object that will spur public interest in climate change. “The ship is designed to capture people’s attention, as well as their hearts and imagination. If we want to make big, bold changes, we need everyone’s help, ”Mr. Olivera emphasized. The Earth 300 ship will be nearly 300 meters long and have a 13-story “science ball”. Olivera wants to bring together a team of scientists working in many different fields. As a result, it helps to come up with new climate solutions with modern technology. Equipped with integrated sensors, artificial intelligence, robots, machine learning and real-time data processing, Earth 300 will also have the world’s first commercial quantum computer. With this technology, the ship can process huge amounts of data collected. The information collected by Earth 300 will be shared with other climate scientists, Olivera said. According to the researchers, Earth 300 will be zero emissions. Because, it is powered by the atomic energy from an onboard salt reactor. Described as an atomic battery pack, Earth 300 is based on the technology of TerraPower – the nuclear reactor design company founded by Bill Gates. “Currently, neither quantum computing nor molten salt reactors are installed on board. It will take an extremely high level of technicality to do that. Then we can talk about the fact that this ship will have no less than a million sensors. Basically, it will be built as a floating computer and that will be a challenge, ”said Olivera. Olivera and his team believe that radical thinking is essential to advancing research and concerns about climate change. “We live at a pivotal moment in human history and face the greatest challenge to civilization. But we also live at a time when we have access to talent, tools and technology to tackle any challenge. There’s no reason not to think big. We want to awaken the world and bring new awareness, ”Mr. Olivera emphasized.

Physical exercise increases body temperature, increases peripheral blood flow, increases blood perfusion to the skin, thereby providing more oxygen and nutrients to the skin, helping to restore damaged skin cells caused by the impact of agents. the external environment such as moisture, sunlight, dust … and free radicals in the body. Physical exercise also increases sweating, helps eliminate toxins, body metabolism products, dirt and secretions of the skin, sebaceous glands, and avoids clogging of the pores. Exercise is also an effective way to combat the general aging of the body, including the aging process of the skin by promoting the production of fibroblasts, skin cells responsible for collagen production, Increases elasticity and rejuvenates the skin. Proper exercise reduces physical, mental and emotional stress, reduces inflammation and overall immune response in the body through cortisol regulation. Regular physical exercise for pre-menopausal and menopausal women has the effect of reducing symptoms of neurological disorders such as hot flashes, sweating; improve sleep disturbances, reduce irritability, reduce psychological stress, improve quality of life. Thanks to that, regulating the functions of the body, the skin will also have a more beautiful and healthy glow. Walking, running slowly, and cycling are simple types of exercise that are easy to perform, do not require complicated training conditions, so almost anyone can easily exercise. Some other types of movements such as GYM exercise, Aerobic exercise require trainees to be instructed, moreover, there are also certain means of exercise, so it is suitable for a few people. Proper exercise helps to have a healthy and beautiful skin. Some yoga moves help skin healthy and beautiful Trikonasana (extended triangle exercise) widens the hips, increases overall strength and cardiovascular system, enhances blood circulation, removes toxins, eliminates free radicals, helps relax, reduces tension straight. The posture of cobra (Bhujangasana) relaxes the back, chest muscles, enhances circulation, regulates heart rate, and breathing, helps the mind to relax. This movement is also good for the digestive system, helps to remove toxins, destroy free radicals. Exercises to prop feet up against the wall (Viparita Karani) or Wall Legs Up with 2 feet up on the wall, blood and oxygen will be deposited on the half of the body, enhancing nutrition for most parts of the brain, skin. facial muscles … Seated twist increases blood flow to the digestive and detoxifying organs such as the liver and kidneys. Camel Pose (Ustrasana) bends back, stretches the entire front muscles, enhances blood circulation, increases skin strength. Some notes to keep skin healthy and beautiful when exercising When exercising outdoors, it is important to choose the right training time. The sun provides vitamin D to help the body absorb calcium, but intense sunlight, more ultraviolet rays can damage and aging the skin. Avoid intense heat from after 10am to 3pm, pay attention to shielding direct sunlight shining on the skin during these times. Should practice in the early morning when the sun has melted the fog or the evening when the sun is less severe. Pay attention to skin and body protective clothing and equipment. GYM exercises with aid can cause blistering or thickening of the contact area, so gloves, training shoes, and belts are essential to protect hands, feet, and knees. Training clothes to ensure cool summer, winter to keep warm, at the same time to absorb sweat, change clothes when wet. Remove makeup before exercising, but use sunscreen when exercising outdoors. Exercising in dry weather conditions easily dehydrates the skin of the lips, so it is important to pay attention to moisturize and drink enough water. Clean skin and body properly after exercise, avoid showering immediately after exercising when sweat persists. Bath water temperature is suitable with the season. The disinfectants in swimming pool water often make the hair dry, so care should be taken to clean the skin after swimming. Avoid overtraining, pay attention to nutrition, drinking water, ensure time and quality of sleep. Adequate physical activity has been shown to improve the physical and mental health of all subjects. Proper exercise has a positive effect on most of the functions of the body’s organ systems. When the body is physically and mentally healthy, the skin will also be healthier and more beautiful.
