The researchers tested graphene’s ballistic missile defense by firing small projectiles at it. They found that the material was stiffer, more flexible and lighter than the Kevlar jackets used in the military today. And, a million layers of material would be only 1mm thick. The Massachusetts Institute of Technology’s (MIT) Soldier Nanotechnology Institute is working on an efficient manufacturing method for a graphene-based chainmail bulletproof armor, which could potentially give the military better protection than with today’s bulky coats. Chainmail (or mail or Maille) is armor made of metal rings joined together in a protective mesh pattern. Can be used for marines, especially those who have to work in harsh environments, bulletproof and protect against the risk of attack by wild animals when doing special missions. 2. Synthetic blood Synthetic blood is much more efficient than natural cells. The most promising technology being studied is a respirator – a theoretical red blood cell made of diamond that can hold gas at nearly 15,000 psi and exchange carbon dioxide and oxygen in the same way real blood cells. Supersoldiers whose breathing cells are mixed with their natural blood will essentially have trillions of miniature gas cylinders inside their bodies, which means they’ll never run out of breath and can stay under. water for hours without any other support equipment. 3. Jump 7 feet (2.13 meters) and run 25 mph (40.23km/h) Scientists at MIT and other research universities are looking to strengthen the human ankle and Achilles tendon with bio-boots that mimic the tendons of kangaroos. Humans equipped with such boots would be able to jump 7 feet (2.13 meters) or more, sprinting at incredible speeds. And run all day without muscle wear and tear. Bulletproof armor. 4. Vaccinations for pain relief DARPA’s Combat Persistence Initiative (short for Defense Advanced Projects Agency of the Pentagon, USA) aims to help soldiers recover almost immediately from injuries. The pain-relieving shot will work for 30 days and eliminate the painful inflammation that persists after the injury. So soldiers could feel the initial agony of being hit by a bullet, but the pain would disappear within seconds. Soldiers can self-medicate and continue fighting until medical evacuation. 5. Fight against sleep Not all animals sleep the same way. DARPA wanted to find a way to let humans sleep with only half of their brains at a time like whales and dolphins, or even skip sleep for long periods like ENU mice. 6. Telepathy Not all brain implants look very comfortable. US Patent Application Richard A. Normann. Part of DARPA’s “Brain Machine Interface” project is to develop better computer chips that can connect directly to the human brain via implants. In addition to allowing soldiers to control robots with just their thoughts, this will allow teams to communicate via telepathy. While the chips have improved, the project has some detractors. Part of the research is the ability to control mice remotely via implanted chips, and some defense scientists worry about the risk of the military having its mind hacked. For example, the movie “Men Who Stare Goats” is based on a book by Jon Ronson about a secret unit created by the US military in 1979. According to the book, the US military believes soldiers can become invisible, go through walls and kill goats by staring at them. Actor Ewan McGregor plays a reporter who stumbles across a member of that special unit as he prepares to go to Iraq, and the reporter and Lyn Cassady – Clooney’s character – continue the unfortunate journey : they were kidnapped, shot and hit by a roadside bomb… 7. Power-assisted underwear Meanwhile, Harvard researchers studied the “soft exoskeleton”. It’s a DARPA-funded robotic suit that’s essentially a series of fabric muscles worn under a garment to assist the wearer in every step or movement. This reduces fatigue and increases strength without requiring the enormous amount of strength that tough exoskeletons require. Gloves and climbing shoes like geckos. 8. Gloves and climbing shoes like geckos Geckos use the tiny hairs on their legs to cling to surfaces on a molecular level. Although the “Z-Man” project does not necessarily give humans the ability to crawl along the ceiling like a gecko, special climbing shoes and gloves will allow soldiers to easily climb the amazing rock face. against or onto skyscrapers without any other equipment, greatly reducing overhead attack. Researchers have made breakthroughs and can actually support a man weighing up to 90.71kg with current prototypes. Experts note that in the civilian field, work on nerve transplants for humans is happening very quickly. In 2017, Elon Musk unveiled a pig named Gertrude with a coin-sized computer chip in his brain, to demonstrate his ambitious plan to create an interface between the brain and the machine.

The front door is the mouth of qi, where energy enters the house. In feng shui, the main door will definitely protect everyone in the house from any negative energy or uninvited guests. To know if the front door is solid or not, check the strength of the door first. Does the lock work? Is it well-repaired? Does it have enough light? The front door is definitely like a gate, creating a barrier between you and the outside world, helping to invite positive energy. 2. Red front door Another way to strengthen the front door is to paint the front door red. Red is an auspicious and powerful color in feng shui. Red is often used in feng shui to transform negative energy and protect. Red belongs to the element Fire and is an energetic, stimulating and dynamic element. 3. Black Natural Tourmaline Rough Stone Crystal Black tourmaline is a crystal that helps absorb negative energy and is an Earth stone. It can help you feel safe and protected from challenging and difficult situations and negative energy. You can also create a protective net by placing a piece of black tourmaline in each corner of a room, house, or under the four corners of a bed. You can place a black crystal, like black tourmaline, on the front door. Black absorbs and protects you from the energy outside your home. 4. The spell Adding a door guard spell can also protect your home. For example, “Om Mani Padme Hum” is a Sanskrit mantra commonly used in feng shui. That is the mantra of Avalokiteshvara, the bodhisattva of compassion. This mantra means “the jewel lies in the lotus”, possibly a reminder of inner beauty, just like the lotus flower can bloom from muddy water. Many Tibetan prayer flags have mantras written on them and can be placed inside and outside the home. Alternatively, you can write a spell (or any protection that makes sense to you) on paper and place it above your door. This way, every time you go in and out, you will activate and receive that protection. 5. Bagua mirror bát The bagua mirror is one of the best home protection methods. It is a round mirror in an octagonal frame and has a bagua print on the edge of the mirror. The bagua, as well as the bagua areas, are connected with the I Ching, an ancient Chinese text used for divination. Let the bagua mirror outside the home, above the front door or large window, point towards negative or dangerous energy. Do not place the bagua mirror opposite the neighbor’s house. 6. Ring the bell You can hang a bell on your front door to alert anyone who comes in and out of your house. Metal bells are the best kind of bells. The bell will protect you. Hang a bell on your front door if you can’t hang it in a commanding position, meaning you can’t see the exit while you’re in bed, at your desk, or cooking in the kitchen.

Recently, a number of unfortunate incidents have occurred in apartment buildings. There are cases where children, even adults falling from higher floors, died or were seriously injured. There is an opinion that it may be due to design errors, but all apartment buildings and high-rise buildings must comply with construction standards, including full safety standards for each item, so it is unlikely to happen. out errors. In fact, the cause of the above cases is largely due to the unreasonable arrangement of objects and the interior of the house, leading to an accident in use. Talking about this issue, Mr. Tran Manh Dat, General Director of a company operating in the field of interior design, manufacturing and construction, said: “Usually when designing balcony balustrades in apartments height of about 1.4 m. However, active children can climb over here. Therefore, in a home with young children, it is very necessary to install additional screens to ensure safety ”. The apartment building should install a protective net on the balcony and avoid placing objects, beds close to the window. Photo: NGUYEN CHAU When receiving a house, even though there are no children in the house, the homeowner should still make a net on the balcony rail and the window to make the living process safe. The current way of installing the protective cable still completely ensures the space for the house. For townhouses, it is necessary to pay attention to the handrail of the stairs, if using the form of bars, the distance between the bars is not too large for children to pass through. Architect Huynh Bao Toan, Director of a mobile home supplier, also instructed: “When designing a house, the architect did it correctly according to the regulation of a handrail of about 1.4 m or more. However, some families often put extra items on the balcony, close to the railing such as washing machines, trees, furniture … When someone climbs these objects, it is very easy to fall out. Modern apartment design often has large windows, families should not set tables, beds close to the windows because it is very dangerous, especially for young children. The interior layout should be carefully calculated if the house has children ”. KTS Toan recommends apartment balconies need to attach protective nets. This not only ensures the safety of people in the house, but also minimizes the drop of things or mischievous children throwing objects on the ground, endangering others. “The current types of safety nets and cables do not violate the safety of the apartment’s escape when there is an incident such as fire and explosion, so people can use it with peace of mind. The bed should be placed in the middle of the room, not close to the window, the two sides should have space to move ”- said architect Toan. One of the risks when the house has young children is that the power outlet is too low, and children are easy to play with. Therefore, families with low power outlets need to install additional covers for electrical outlets to ensure safety.

The protective net must be easily cut off Regarding the fact that some apartments are fitted with protective nets to ensure the safety of children in the balcony and windows, Associate Professor, Dr. Tran Chung admits that this is a quite convenient and effective tool in existing condominiums. now on. However, he noted that the material of the protective nets should be properly chosen because it is related to ensuring safety against fire and explosion. “As a rule, the balcony area of ​​the building has a very important task to rescue and rescue when there is a fire or incident in the building. The rescue force will use the means to pick up people through the area. balcony, “said Mr. Tung. Therefore, the space above the handrail is very necessary, absolutely not sealed or reinforced with fences, iron cages. If people install protective nets, it is necessary to use materials that are easy to cut off, not too solid. Assoc.Prof. Dr. Tran Chung, former Director of the State Department of Construction Quality Inspection (Ministry of Construction). Photo: ASHUI. Through the incident of the girl escaping despite falling from the 12A floor of the building that just happened, Mr. Tung said that this was an extremely rare event. Through each case, the authorities need to investigate and clarify the cause to widely propagate safety conditions in the apartment. Families living in the apartment building should observe and re-evaluate the safety level in the balcony hallways and their windows to adjust accordingly; Avoid unfortunate cases, especially in large urban areas with dense apartment density. The railing is up to standard but can still be accidental Talking about the height of the railing of the apartment building, Associate Professor, Dr. Tran Chung said that these details must meet the standards for the building to be accepted and put into use. “The regulations of the Ministry of Construction are very clear in this regard, the balustrades of apartments and high-rise buildings are specified that the height must be 1.4 m. The regulation also states that the structure of the handrail must not be there are more structures to climb, “said Dr. Tran Chung. In addition to the already specific technical legal corridor, in urban areas with high density of high-rise buildings, it is necessary to pay attention to checking and controlling safety conditions. Local inspection units, State management agencies in the construction field must strictly conduct pre-acceptance tests before they can be put into use. “The legal corridor and tools for us to manage have been guaranteed. However, similar cases still occur. We have to look at each case to dissect the cause”, Assoc. Race said. According to Dr. Tran Chung, if people install protective nets on the balcony, it is necessary to use materials that are easy to cut off, not too solid. Photo: Duc Anh. According to Mr. Tung, there are several main causes of these unfortunate accidents. In which, the balcony area is often used by people as a place to store, plant flowers and ornamental plants, accidentally turning into steps for children to climb and easily climb over the railing. Along with that, the balcony of the building is absolutely not a play place for children, especially when not supervised by adults. He suggested families with children should regularly close the doors to the balcony area, limit the opening of large-sized windows, limit bed racks, cabinets, window furniture … According to the construction standards of housing and public works in Vietnam issued by the Ministry of Construction in 2008, high-rise buildings or apartment buildings with children under 5 years old living or frequently frequented, balustrades must meet standards. Standard: A handrail gap does not pass a sphere 100 mm in diameter and is not constructed to allow children to easily climb over the railing. For houses, offices, schools, offices and public works, the minimum height is 1.4 m in the lot and terrace at the positions of 9 floors or more. The handrail in the stairs and other locations is from 0.9 m to 1.1 m. Mr. Nguyen Ngoc Manh: ‘I just want a simple life’ Driver Nguyen Ngoc Manh said that after saving the girl who fell from the 12A floor, he was asked by many people. This man just wants a simple life to continue his unfinished plans.

Apartment safety net is expensive After the incident took place on the afternoon of February 28 in an apartment in Hanoi, many families hired workers to install protective nets for balconies, windows, and corridors. The price ranges from 130,000 to 250,000 VND / m2. Apartment 60B Nguyen Huy Tuong (Thanh Xuan district, Hanoi) is one of many buildings that recorded accidents when children fell from a balcony on a high floor. The apartment where H. fell two days ago is located on the back, adjacent to 62 Nguyen Huy Tuong building. People said that when she discovered the incident, the little girl climbed over the railing of the apartment. The corrugated iron roof where Mr. Manh jumped to support baby H. sank in a corner. The people at the building are still not completely shocked by the incident. “My house is in the front, until last night my children told me to know the incident. I have lived here for 4 years. Right from the moment I got the house, I installed a protective net to pull from the railing to the ceiling outside the balcony so that when the children come to play, we will be more secure ”, Ms. P., resident on the 10th floor, said know. According to observations, the handrail of the apartments is about 1.3 m high, the distance between the bars is 15 cm. The apartments in the opposite apartment building are also in the state of houses with protective nets and no houses. According to Zing’s survey around Hanoi, the apartments of an apartment building on Nguyen Chi Thanh street (Ba Dinh district) have a rather low railing design, but out of 6 apartments on the photo, only one apartment is installed. protective mesh system outside the balcony. Designing an X-shaped handrail in an apartment on Hoang Dao Thuy street. In N3B building (Thanh Xuan district), many apartments have installed protection systems outside the railing, the rest have iron frame systems, with aluminum and glass frame doors. Most apartments in an apartment on Nguyen Chanh street are fitted with protective nets, some are ceiling-mounted, some only have a plastic mesh system below to facilitate clothes drying. People live in apartments or leave pots of plants on the balcony for decoration. If there is no protection system on the railing, the young children will easily climb up thanks to these potted plants. “I just moved here to live. From the beginning, the building management has talked to the apartment owner about installing a protective grid system. The apartments here have a balcony near the kitchen, and a backpack for drying clothes. Although there are seldom children at home, I still install it from the beginning to ensure safety, partly to prevent theft, ”said Ms. Thu Giang, living in an apartment in Long Bien district. To avoid small children climbing on flower pots on the balcony sticking to the railing, Mr. Cuong (Long Bien) installed a safety net system early from the time of repairing the apartment. Mr. Cuong also installed a protective net on the window in the children’s bedroom. According to the Vietnam Construction Code on housing and public works – safety of life and health issued by the Ministry of Construction in 2008, the minimum height of handrails is specified: Houses, offices, schools school, office and public works of loggias and terraces at the position of 9 floors or more, the minimum height is 1.4 m. For works used by children under 5 years old, the balustrade must be constructed not for children to easily climb over and the gap must not exceed 10 cm wide. With handrails or loggias used with glass material, the glass is protected by a fixture, ensuring it is solid, no gaps are inserted into the 7.5 cm-diameter sphere, difficult to climb over to prevent prevent falling.
