Recently, the team upgraded the technique to power and program the multipoint biostimulator from a single transmitter. Thanks to new research, electrical and computer engineer Kaiyuan Yang and colleagues at the George R. Brown School of Engineering (Rice University) won an award at the Society of Electrical and Electrical Engineers’ Custom Integrated Circuits Conference death (IEEE). The researchers performed experiments showing that an alternating magnetic field can be controlled by a battery-powered generator outside the body. The transmitter can be mounted on a belt or harness, powering and programming two or more implants at least 60 millimeters away. The implant can be programmed with a delay measured in microseconds. That could allow them to coordinate the activation of multiple wireless pacemakers in individual heart chambers, says engineer Yang. “Our study shows that it is possible to program the implants to stimulate in a coordinated pattern. We sync every device, like a symphony. That gives us a lot of scope in stimulant treatments, whether it’s for the heart rhythm or the spinal cord.” The scientists also experimented using small implants. Each tissue is about the size and weight of a vitamin. Experiments performed on hydra vulgaris rodents have demonstrated that, for at least a short distance, such devices can stimulate two separate hydras to contract. Then, activate a fluorescent tag to respond to electrical signals and respond at controlled amplitudes along the rodent’s sciatic nerve. “A study on spinal cord regeneration showed that multipoint stimulation in a certain pattern helps restore the nervous system. Several clinical studies are underway, but all are using desktop devices. There is no implantable tool that can do this,” said engineer Yang. Lab devices, called MagNI (for electromagnetic nerve implantation). MagNI was introduced early last year as a cordless spinal cord stimulator for power and programming. That means the wire does not need to be passed through the patient’s skin. Because, putting the wire through the skin is a method that can cause infection.

Wowy is not only a famous rapper, has a great voice and influence on the Hip-Hop and Rap enthusiast community in Vietnam, but for a long time, Wowy is also a passionate artist of graffiti art. From an early age, Wowy showed off his talent in street painting and was highly appreciated by the Graffiti world. It is that passion that inspired Wowy to release the song HIT Where I live is known by Rap enthusiasts and made a name for the “elder” in the Rap community in Vietnam. Visitors to Wow’s exhibition From April 27th, Wowy and his friend Tuan Andrew Nguyen opened the exhibition “End of the End Dream” in Ho Chi Minh City, with the hypothetical message that if the world is only you or you are What is it like to be death close by? Wowy gave a picture explanation. In particular, in the paintings at the exhibition, there are pictures shown through the poetic drawing by Wowy extracting blood from his own body to make ink on tissue paper. In the poem there is a written statement: “One prayerful earth for my father and my mother – I pray to God to make the Buddha safe for my brothers and sisters …” “This is my request- I just want to ask people to listen. .. Wowy said: “Wowy was a person who didn’t know how to show his love to people. When I realized I was growing up, Wowy had to learn how to show his love more by himself and spread this love as much as possible to the society, people, worldview around Wowy I know how to cherish and love more So I wrote, I wonder if it can be called poetry or not? ” Painting is represented by Wowy in blood In addition, at the exhibition, through the pictures, viewers can also see the true generosity, expression and bohemian nature of Rap’s souls. Wowy took pictures with critic Ly Doi Let’s take a look at some pictures at the exhibition made by critic Ly Doi: Sponsorship news

However, the mutant non-phytoplankton propagated by tissue culture method is surprisingly cheap.

More than 6,000 VND a mutant orchid 5 white wings Phu Tho

Recorded in forums, groups on social networks, some people are selling mutant orchids seeding and tissue transplanting.

For example, the 5 white Phu Tho, 5 white Hien Oanh mutant orchids, on the market, sell for 1.5-4 million VND / cm, these two plants are still produced by tissue culture method, which costs 160,000. -800,000 VND / bottle, depending on the number of trees.

Mr. Hai Phan, specializing in selling mutant orchids transplanting tissue in Binh Chanh district, Ho Chi Minh City, said that his shop has all kinds of mutant non-scallop orchids such as 5 white Phu Tho wings, 5 white Hien Oanh wings, 5 wings. White Peace …

In particular, the 5 white Phu Tho and 5 white Hien Oanh wings are the most popular mutant orchids on the market with a price of 160,000 VND / bottle of 20-25 trees, which is just over 6,000 VND / tree.

“Plants, taking care of 2 years, will flower, commit to producing the right type of 5 white petals,” he said and explained that propagation by mass transplanting method should be cheap compared to the kie market. Small quantity should be expensive.

The owner of this shop also said that he is the one who implants that mutant spread tissue. “Transplanted mutant orchid plants will produce flowers similar to kie types, but will have slight variation, which means accuracy from 90-95%”, Mr. Phan shared.

Similarly, Mr. Vu Cong (Thu Dau Mot, Binh Duong) also sells mutant orchids of various types such as: 5 white Hien Oanh wings, 5 Phu Tho white wings, 5 Minh Vu white wings, Hong beauty, Hong Yen aquatic products … with prices from 800,000 to 1.2 million VND / bottle of 25-30 trees.

In addition, he also sells seedlings with a price of 250,000 VND / bottle per 40 trees, buying over 50 bottles will have a wholesale price. “If you take care of it quickly, it takes about 6-8 months to flower, and the tissue transplant method must take 1-1.5 years,” said Cong, who is more expensive because of the high technical requirements and the probability of flowering like the mother plant is also higher. This type he has just tested for more than a year but has no results, is expected to flower later this year.

Currently, each month he provides to the market about 200-300 bottles of tissue transplant mutant spreading. “I sell to customers but do not warrant flowers for anyone because I am not sure”, added Mr. Cong.

Not only that, on e-commerce sites such as Lazada, Sendo … also sell mutant orchids sowing seeds or transplanted mutant orchids with prices from 70,000-500,000 VND, depending on type.

It is possible to mass transplant tissues to spread billions of mutants

At the Institute of Vegetable and Fruit (Ministry of Agriculture and Rural Development) is also propagating thousands of mutant non-scallop orchids by tissue culture method.

Exchange with Zing, Assoc.Prof.Dr. Dang Van Dong, Deputy Director of the Fruit and Vegetable Research Institute, confirmed that mutant non-scallop orchids can be fully propagated by tissue culture method in large numbers.

According to this PGS, today many crops including mutant orchids can be created artificially (through physical and chemical agents) and when there are “mutant orchids”. in the true sense, with genetic stability, it is completely possible to asexual propagation (by cuttings or improved tissue culture).

A complete tissue culture (in the laboratory) process takes at least 10-12 months. Photo: Hai Phan.

Cuttings are easier to do, but the propagation coefficient is slower, while cell culture (also essentially cuttings in the optimal environment and conditions) requires high technology, large initial investment, but The multiplication coefficient is high, the quality of the plant is better.

“Both of these two methods retain the genetic properties of the mother plant and after a year can multiply thousands of seedlings,” he confirmed.

In addition, this Associate Professor said that the Fruit and Vegetable Research Institute has been multiplying thousands of mutant non-scallop seedlings with kie ordered by a customer. “The price of these seedlings is just equivalent to other normal orchids”, the expert information.

“As a biologist, scientific research on flowers in general about orchids in particular, I myself do not understand why ‘mutant orchids’ are not so terrible, they can be propagated in large numbers. but it is so expensive, “he added.

Faced with the fact that many people were deceived when buying the billion, Associate Professor, Dr. Dang Van Dong recommended that before buying, selling, and exchanging consumers, they should consider, learn carefully, and ask the seller to have a guarantee contract. closely seeded to avoid any unfortunate occurrence. At the same time, the seller needs to make commitments to ensure the right varieties and quality, including guidance for the buyers on planting and care techniques for such orchids.

First, when you first buy a pan, pour water about 2/3 of the pan. After red, turn on the stove and cook the cake over high heat. Only cook until the water is evaporated and bubbly. After that, turn off the heat and pour the water away.

Use tissue to wipe away any remaining water in the pan.

You continue to put the pan on the stove, to low heat. Then, absorb some tissue with cooking oil and wipe all over the pan. Just do this for about 30 seconds to turn off the heat and let the pan cool.

Repeat wiping the pan with oil blotting paper 2 more times.

This way will make your non-stick pan more durable, comfortable to use without worrying about scratching or peeling.

Some note when using non-stick pan

Pour the oil into the pan before the pan is hot

Pouring oil into the pan is hot will make the non-stick layer easy to peel, toxic to the user as well as reduce the life of the pan.

Use cookware made of wood or heat resistant silicone

Absolutely do not use a metal spoon or spoon to stir food in a non-stick pan. This will make the surface of the pan easy to be scratched, and the poisons can easily be absorbed into the food, causing harm to the user.

Limit seasoning directly when using a pan

Spices such as fish sauce, salt will affect the non-stick layer of the pan. The surface of the pan is prone to pitting, damages the non-stick coating and reduces the life of the pan.

No need to use too much grease

Non-stick pan is used to prevent food from getting close to the pan, so when frying, women do not need to use too much grease, causing waste. In addition, a large amount of grease will increase the temperature when using the non-stick pan. Non-stick layer if heated at high temperature will easily peel off, affecting the life of the pan as well as the health of the user.
