Study Shows Cannabis was Food Staple for Ancient Chinese Dynasty

Researchers studying an ancient tomb in China have found direct evidence that cannabis was a staple food crop during the Tang dynasty more than 1,000 years ago. To get more news about ancient chinese bedroom, you can visit shine news official website.

Previous research into the civilizations of ancient China has shown that cannabis was an important crop for thousands of years, with historical texts showing that the plant’s seeds were a staple food consumed in a type of porridge. And now archaeological evidence from central China is confirming the significance of cannabis during the Tang dynasty, which ruled the country from 618 to 907 A.D.In 2019, workers at an elementary school playground construction site in Taiyuan, Shanxi province discovered an ancient tomb buried underground. Escaping discovery for more than 1,320 years, the remarkably dry environment of the tomb had preserved the wall paintings and artifacts found inside.

The researchers determined that the discovery was the tomb of Guo Xing, a cavalry officer who had fought with Tang emperor Li Shimin, or Taixzong, in a series of fierce battles on the Korean peninsula. Among the artifacts discovered in the tomb was a jar containing staple foods, which included cannabis seeds and the remnants of their husks, according to a report by the South China Morning Post.

“The cannabis was stored in a pot on the coffin bed amid other staple grains such as millet. Obviously, the descendants of Guo Xing buried cannabis as an important food crop,” said Jin Guiyun, a professor with the school of history and culture at Shandong University and a co-author of the study published last month by the peer-reviewed journal Agricultural Archaeology.

The cannabis seeds were significantly larger than those of today’s varietals, suggesting that a cultivar of cannabis had been bred specifically for grain. They were so well preserved that some still showed their original color. The researchers noted that the seeds still had their husks, which can contain the psychoactive cannabinoid THC. According to the Compendium of Materia Medica, a book written by herbalist Li Shizhen about 500 years ago, eating too many cannabis seeds that still had their husks could “make a person run about like mad.”
“Cannabis seeds with husks are not only related to the high lignin content of the husk and its hard texture, which can reduce the chance of mold and prolong the storage time, it may also stimulate the nerves and cause hallucinations due to the consumption of husk for religious and medical purposes,” researchers with the Taiyuan Municipal Institute of Archaeology wrote in a report on the study.

Cannabis was an important crop during the Tang dynasty, providing food, fiber and medicine for the ancient civilization. But the Taiyuan region was wetter and warmer at that time, making rice the most common grain in the area.

However, the artifacts placed in the tomb by the family of Guo Xing did not include rice as would be expected. Instead, the researchers found cannabis seeds, perhaps reflecting the personal food preference of the ancient warrior, who lived to the age of 90.

In ancient Chinese texts, cannabis was known as one of the five staple food crops known as wu gu. Archaeologists have discovered cannabis in tombs found across the country, some as old as 6,600 years old. Previously, researchers have theorized that the presence of cannabis in tombs indicated the use of the plant for spiritual and funerary purposes. But the evidence discovered in Guo Xing’s tomb illustrates the importance of cannabis as a staple food crop as well.

Chinese women face a complex homecoming after studying in Australia

When Li Fang* returned to China after studying at university in both Australia and New Zealand, she didn't think she'd changed all that much.To get more news about traditional chinese women, you can visit shine news official website.

But her family and friends soon noticed."People around me thought I was different," she says."I asked them, 'What's the difference?' They said, 'Sometimes your opinions and your speaking style are very direct.'"

In hindsight, she agrees. "I think my personality changed a lot after going abroad. I like freedom, I like independence," she says.It was not only those close to her who noticed. After Li got home, she undertook an internship with the Chinese government.

"No-one [in my office] had an international background … The Chinese style in government is: Everyone is quiet and no-one should speak [up] about anything. Everyone just follows," she says.

"When you come back to China and you're not used to this, people around you think you're strange."Li is not alone. Many Chinese international students — particularly women — find themselves changed after studying in Australia.

And many of these young women are determined to chart a new course for themselves back in their home country.Fran Martin, associate professor at the University of Melbourne, recently completed a five-year study where she followed a group of 56 Chinese women who studied at university in Australia, including Li.

"Women students make up a majority of the students who come to us from China," Dr Martin tells ABC RN's Counterpoint.

"Many of them find a very meaningful experience, in terms of their personal, subjective sense of themselves and for their plans in their life as women.

"[They may] pivot or reorient as a result of being away from social and familial surveillance at home and living somewhat independently here in Australian cities."Dr Martin says many participants spoke about "getting a kind of tolerance or understanding of non-standard ways of living".

"Whether or not you do these yourselves [or see others do it], from dyeing your hair blue, to cohabiting with partners before marriage, to not having a standard 'wife and family' life plan."

But she says these new ideas and values often collide with a more conservative reality back in China. They experience this when returning to the family home, or through broader state and cultural pressures, or both.The general Chinese public culture and the parent culture has encouraged them strongly towards professional careers and a high level of education … But then there is renewed and intense pressure on women in their mid 20s to reorient suddenly towards marriage, children and family care."

She says these women come back with valuable degrees, "but then they're thrown back into that sort of neo-traditional sense of what a woman's role and identity should be as she moves through that part of her life".

"They may find that they're quite competitive for some professional jobs. At the same time, at least some members of their family and extended family will say, 'When are you getting married?' or 'When are we getting grandchildren?'"

Cold Extrusion of Steel

Extrusion, though one of the most important manufacturing processes today, is a relatively young metalworking process. The cold extrusion process involves forcing a billet of material through a die at room or slightly elevated temperatures, producing a continuous product of constant cross-section. Numerous metals are suitable for cold extrusion, including lead, tin, aluminum alloys, copper, titanium, molybdenum, vanadium, and steel.Get more news about Precision Cold Extrusion,you can vist our website!

A wide variety of parts can be produced, including collapsible tubes, aluminum cans, cylinders and gear blanks. Cold extruded parts do not suffer from oxidation and often have improved mechanical properties due to severe cold working, as long as the billet temperature remains below the re-crystallization temperature.

Cold extrusion technology permits the forming of a part to the desired size and shape by moving the metal at room temperature into the die. Sufficient force is required to exceed the yield strength of the stainless steel and ensure plastic deformation results, enabling the metal to fill out the die cavities to extremely close tolerances. Although there are many different cold extrusion operations, all are variations of one or more of the following:

Forward extrusion forces the metal to flow in the same direction as the descending punch and through a hole in the die to form the required shape and dimensions, as shown in Figure 1a). Forward extrusion is especially useful in the production of bolts and screws, stepped shafts, and cylinders.

Backward extrusion forces the metal to flow upwards around the descending punch, as illustrated in Figure 1b). Extrusion pressures are generally higher and slug preparation is more critical.

Upsetting is the gathering of metal in certain sections along the length of a bar, rod or wire as shown in Figure 1c). The metal is forced to flow at right angles to the motion of the tolling. Upsetting is often performed in conjunction with backward or forward extrusions.

FCL type flexible sleeve column pin coupling

FCL elastic sleeve pin coupling is characterized by simple structure, convenient installation, easy replacement, small size and light weight, so it is widely used. If the relative displacement of two shafts can be kept within the specified range after installation and adjustment, the coupling will have satisfactory service performance and long service life. Therefore, it can be widely used in various medium and small power drive shafting driven by motor with small load, such as reducer, crane, compressor, conveyor, textile machine, winch, ball mill, etc.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!

The elastic sleeve office is a compression deformation. Because the elastic sleeve is thin, small in size and limited in elastic deformation, the elastic sleeve pin coupling can repay the axial displacement and elasticity, but the allowable compensation amount for axial displacement is small and the elasticity is weak.

FCL type elastic sleeve pin coupling is based on the locking force of the pin group and sprouts on the friction torque of the contact surface, and compresses the rubber elastic sleeve to transmit the torque. It is suitable for medium and small power shafting transmission with good rigidity of mounting base, relatively high alignment, half large impact load and low requirements for vibration reduction.

The centrifugal cutter of prior art be mostly the back to, promptly the bending direction of blade is opposite with the direction of air-flow, this centrifugal cutter has very tangible characteristics, be exactly that air quantity is very big, but static pressure is little.A lot of resistance parts are arranged in the centrifugal cutter, comprise vaporizer, electric heater and volute etc., the resistance parts form resistance to the air-flow in the centrifugal cutter, therefore need overcome resistance by static pressure, the effective way that overcomes the static pressure resistance be with afterwards to centrifugal cutter change the centrifugal cutter of forward direction into.The centrifugal cutter of forward direction is meant the centrifugal cutter that the bending direction of blade is consistent with the direction of air-flow, and the characteristics of the centrifugal cutter of forward direction are that air quantity is not very big, but static pressure is big, and higher static pressure can be provided, and is used to overcome bigger system resistance.In the practice,, need the blade more than 43, need motor that very high torque is arranged simultaneously, that is to say, do more merit, need more energy in order to improve air quantity.The experiment that this is carried out, effect are very undesirable.
Simultaneously, as shown in Figure 1, it is thin again that blade is done, and physical thickness is also arranged, when last blade during near the wedge angle of whirlpool tongue 1, this blade and wedge angle distance are very little, blocked air-flow, wind just blows less than wedge angle, in this of short duration time, form the noise of whirlpool tongue 1 and impeller 3, academicly claimed the abnormal sound (BPF) that produces when this skims over whirlpool tongue 1 for blade.Each blade carries out the synchronism running one by one, has produced pulsing airflow, and pulsing airflow has produced pulsation again, thereby the abnormal sound under the certain frequency has just been arranged.
There is the defective that air quantity is little, noise is big in the centrifugal cutter of prior art, this be because:
At first, the whirlpool tongue 1 of prior art centrifugal cutter has only one, and whirlpool tongue 1 is too little from the gap of impeller 3 external diameters, and then fan noise increases severely; If the gap is too big, then air quantity reduces.Consider under the situation of noise, require to guarantee enough big whirlpool tongue 1 gap.

BEST RANGEFINDERS FOR HUNTING IN 2022

This is a review and comparison of the best rangefinders for hunting in 2022. You’ll find the best hunting rangefinders for the money, best long-range hunting rangefinders, best rangefinders for bowhunters, best budget rangefinders for hunting, and best rangefinders for both rifle hunting and bowhunting.Get more news about Golf Rangefinder Slope,you can vist our website!

I break down each rangefinder on this list by the most essential hunting criteria so you can easily find the information you’re looking for.

Rangefinders will be able to pick up different objects at different ranges. For example, it is much easier for a rangefinder to pick up reflective objects than deer.

Rangefinder manufacturers will often use the reflective range when they state how far a rangefinder will range, but be aware of this and make sure to check how far it will actually range on non-reflective targets. A good rule of thumb is about 50% of the reflective range.
What Is Angle Compensation?
Angle compensation is a mode in a rangefinder that automatically calculates the angle of a shot so that you’re on target every time. Without angle compensation, your shots can be incorrect. The steeper the angle the worse your shot placement will be without angle compensation.

Angle compensation is a rudimentary calculation but is perfect for bow hunting and close-range rifle shooting (within about 400 yards).

What Is Line of Sight (LOS)?
Line of Sight (LOS) is the range to a target without any angle compensation. It’s just a straight line to the target without factoring in ballistics and gravity. This isn’t what you want for closer-range shooting because there is no angle correction.

Angle compensation is a rudimentary measurement that works well to about 4oo yards roughly. Since angle compensation is rudimentary it will not work for long-range shooting because more data needs to be taken into consideration for precise long-range shooting.

For this reason, long-range hunters shooters will plug LOS information into a ballistics calculator which will then compensate for the angle more accurately using more metrics.

Are Cheap Hunting Rangefinders Worth The Money?
I don’t recommend buying rangefinders under 150$, especially under 100$, unless you find a good deal or sale on a more expensive rangefinder. This is because under this price point you start to see pretty junky rangefinders. They often don’t have great build quality or they start to malfunction over time, especially in non-ideal weather conditions.

Further, some cheap rangefinder companies will not have angle compensation and will only read Line of Sight (LOS) leading to inaccurate measurements for hunters. A good range finder will last a very long time, work reliably, and will save frustration in the long run.
