Transporting fish without water


Researchers of the Shandong Institute of Commerce and Technology in Jinan have developed a method that makes it possible to keep fish alive without water for up to 72 hours.

Inspired by animals who become dormant in winter, Doctor Zhang Changfeng, the founder of the project, developed a similar system by manipulating the metabolism of the fish by lowering its temperature. By doing so, the fish enter a dormant state and are able to survive without water for up to 3 days.

"In nature, animals, like frogs and snakes usually need dormancy. Fish are also heterothermic animals, [meaning] that external temperature will effect its metabolism. In this case, we could decrease the metabolism via reducing the external temperature. We could turn the temperature into the so-called 'biological freezing temperature' and the fish will go to a dormant state," said Doctor Zhang Changfeng.

Zhang Changfeng explained that the project began in 2010, and that the team has "done research on hypnotising the fish, waterless packing, transporting and revitalising. We have built up the complete procedure."

"In the end of 2019, we developed the commercialised exploration of the research. Where we transported turbot fish from Shandong Province to Hainan Province, and did another trial by transporting the Boston lobster within the city," he added.

Another step in the IC production chain is done domestically
hi MortyandRick

thanks for the article

To the experts and knowledgeable member here in SDF, I didnt know that it takes a lot of steps/process to make a chip. After reading this article is China is able to indigenized all the process?

I now realize the herculean effort China IC industries had gone thru, RESPECT!!!!

Huawei maintained a slight edge over Samsung in cell phone sales in May:
Samsung cedes smartphone top spot to Huawei again in May
The Korean first lost its No.1 spot in April

1593639052706.png

Samsung Electronics have again ceded its top spot in global smartphones sales to Huawei in the month of May, according to market research firm CounterPoint.

The Chinese company controlled 19.7% market share while the South Korean tech giant was just behind with 19.6%. A total of 81.97 million smartphones were sold in May.

Samsung first lost its top spot to Huawei in April. The Galaxy maker had a 19.1% market share that month while its Chinese rival controlled 21.4%, taking the top spot for the first time. A total of 69.37 million smartphones were sold in April.

Samsung’s closing of the gap in May was attributed to the sales rise in the US. The world’s largest economy saw smartphone sales rise 56% in May from the previous month. 8.4 million smartphones were sold in the US in May compared to the 5.4 million in April. Samsung controlled 33% market share there in May, behind Apple’s 41%.

The South Korean tech giant is likely benefiting from US sanctions against Huawei that limits its use of Google’s mobile services. The Chinese companies will likely further feel the brunt of the sanctions later this year as its chip-making subsidiary HiSilicon won’t be able to use TSMC as a contract chip maker.

Huawei’s fate after September remains uncertain due to the sanctions and the resultant problem it faces in securing semiconductors, CounterPoint noted. Samsung, meanwhile, is strengthening its mid-tier Galaxy A line-up and is expecting to launch its Galaxy Note 20 series, Galaxy Fold 2 and S20 Fan Edition later this year that will pique consumer interests.

A person familiar with the matter said it was a strong possibility for Samsung to lose its top spot to Huawei completely this year if it weren't for the US sanctions against the Chinese company.

Transporting fish without water

Interesting research with significant economic value.

A few years ago, I was in the central New Jersey area. Went for dinner at a Chinese seafood restaurant. Their fish tanks were filled with swimming live fishes like groupers and sea basses. And the price was very reasonable. I asked if they were wild caught locally. The waiter told me that they were farm raised in China and air flown in water tanks to keep them alive. Several plane loads arrive New York City daily from China and distributed to local area restaurants and fish markets. I understand they are also doing the same in the West Coast area also.

This technology will allow much more fishes to be flown by air at an economic rate. It will help many poor maritime economies to supply fresh seafood to China and other Asian countries whose consumers value fresh seafood.

Highly recommended. There are several things there that blows my mind, starting with the 5G robot tractor at the start to the 1000 atom plus quantum entanglement at the end. The tunnel boring machine that is going to be sold to Australia is impressive. This YouTuber condenses what would take several pages of articles into a simple entertaining video that summarizes these latest achievements.

One of the 3D models of China's exascale supercomputers debuted online on July 1. All 3 of China's exascale computer projects will use CPUs and high speed interconnectors manufactured in China.

China’s three exascale systems are all built around CPUs manufactured in China. They are to be based at the National University of Defense Technology, using a yet-to-be-announced CPU; the National Research Center of Parallel Computer Engineering and Technology, using a nonaccelerated ARM-based CPU; and the Chinese HPC company Sugon, using an AMD-licensed x 86 with accelerators from the Chinese company HyGon.
Will China Attain Exascale Supercomputing in 2020?
The U.S., China, Japan, and the EU are all striving to reach the next big milestone in supercomputing, but only China has claimed it will do so this year

As more than one person said on this forum, China may well choose to keep their mouth shut even if they achieve some breakthrough, just to avoid agitating the U.S. politicians further.

Hi supercat

Its a good thing that China had an ARM CPU, cause INTEL had stop supplying INSPUR.

Intel Halts Chip Supply to Leading Chinese Server-Maker


What’s new:
U.S. chip giant Intel confirmed to Caixin that it has stopped supplying its products to Inspur, China’s largest maker of computer servers.

An Intel representative described the move as temporary and estimated the suspension would last for about two weeks. Intel took the step to allow the company time to make adjustments to comply with relevant U.S. laws, the person said.

Why is this happening: On June 25, Inspur was named by the U.S. Defense Department as one of 20 Chinese firms that were owned or controlled by the Chinese military. Others on the list included telecom equipment maker Huawei, and surveillance equipment maker Hikvision.

Potential impacts for companies included on the list were not immediately clear at its time of publication.

A Chinese company has developed the first China-made ultra-small 5G communication module, which can be widely used in smart industry, smart energy, industrial robots, drones, and other fields.
The AI-NR11, Developed by Changhong's subsidiary Sichuan AI-Link, is especially suitable for scenarios where the module size is required, such as ultra-small cameras and precision measuring instruments.

This is another breakthrough after the world's first 5G industrial internet module (AI-NR10) rolled off the assembly line at Changhong.

Both the AI-NR11 and AI-NR10 are designed using Shanghai HiSilicon's 5G module middleware solution, supporting 5G/4G/3G network standards and both SA and NSA networking methods.
It can achieve download speeds of up to 4.6Gbps and upload speeds of up to 1.2Gbps.
The AI-NR11 5G module is designed in a standard M.2 package and is only 5mm wider than a 1 yuan coin.

It took less than five months from the launch of the world's first 5G industrial Internet module to the successful development of the module.

In March, AI-Link and HiSilicon signed the "5G world's first license" cooperation agreement to accelerate the 5G layout.
Sichuan AI-Link has a production capacity of 12 million modules per month and has provided connection service for 300 million IOT terminal products for domestic and foreign mainstream enterprises.

That's a pretty short ban I suppose. They must have realized it would hit pretty hard on the bank account.
