Multiple armed groups claim to _invade western Russia_

With the upsurge of industry development, 電子煙主機 The expressive force in the market has also been very good, bringing many brand-new high-quality experiences to users.https://www.vapehost.tw

According to a Reuters report on March 12, at least two armed groups headquartered in Ukraine said on social media that they invaded Russia’s western border on the 12th.

Reports said that both the Russian Free Corps and the Siberian Battalion announced on the Telegraph social platform that they had launched an attack from Ukraine to Russia.

The Russian Free Corps said in the telegram: We will regain our land from (Russia) centimetre by centimeter.

Russian officials say the groups are puppets of the Ukraine military and the CIA. Moscow says the latter is trying to incite chaos in Russia.

Andreyusov, spokesman for Ukraine’s military intelligence department, said that these organizations operate on Russian territory independently of Ukraine.

The Russian Freedom Corps ‘statement also appears to point to the upcoming Russian presidential election this weekend. The group said: People will vote for whom they want, Russians will live a free life.

What can the security staff see on the screen during security check Uncover the secrets of security c

　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.Therefore, walk through metal detector Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://secuzoan.com/

　　

　　security check

　　

　　How does the security inspection machine work?

　　

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　

　　security check

　　

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　

　　security check

　　

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

The U.S. behavior while supplying arms to Israel while aiding Gaza has been widely criticized by the international community

After screening and investigation 電子煙主機 It is likely to become a new force driving economic development.https://www.vapehost.tw

Following the airdrop of aid supplies, U.S. President Biden announced that he would build a dock in the Palestinian Gaza Strip and provide aid by sea. The United States ‘move to deliver weapons to Israel while providing humanitarian aid to Gaza in the form of airdrops and construction of docks has been widely questioned by the international community.

U.S. President Biden announced in his State of the Union address on the 7th that the United States will build a temporary port on the Mediterranean coast of the Gaza Strip to receive supplies. The U.S. Central Command said on the 9th that a U.S. military logistics support ship had set off from the Langley-Eustis Joint Base in Virginia for the eastern Mediterranean Sea, carrying the first equipment needed to establish the temporary port. The U.S. Department of Defense earlier issued a temporary port construction timetable, saying that the project would require more than 1000 soldiers to participate and could take nearly 60 days.

Before announcing the construction of a temporary port, the United States also chose to provide aid to the Gaza Strip through airdrops. However, the effectiveness of these U.S. actions was questioned.

Abil Etfa, spokesman for the World Food Program in the Middle East: Airdrops cannot compete with or replace truck fleets in terms of the quantity of supplies delivered; they are also much more expensive than land fleets in terms of cost. The amount of airdropped supplies is extremely limited. Only a very, very few people can benefit from it.

The Council on American-Islamic Relations has called on the U.S. president to stop playing both a firefighter and an arsonist in the Gaza Strip.

Providing both food and bombs, Biden may involve himself in the Gaza War. The New York Times published an article titled on the 8th, saying that although Biden decided to provide assistance through air and sea transportation, the other side is still providing bombs to Israel. The United States may suddenly find that it is already at the same time to some extent. The position of both sides in the conflict has raised questions and concerns about its role.

A friend posted that the United States ‘actions were extremely hypocritical. The hypocrisy and double standards of American politicians are world-class. What the United States is doing is like cutting off people’s legs and giving them several wheelchairs.

Michael Fahri, United Nations Special Rapporteur on the right to food: I have reason to believe that this is a show to cater to the American audience as the U.S. election approaches. This is the only reasonable explanation. According to my previous description, from a humanitarian perspective, an international perspective, and a human rights perspective, the United States ‘airdrops and the establishment of sea ports seem ridiculous.

Some people in the Gaza Strip even bluntly said that the so-called aid efforts of the United States are actually useless. The United States has not made any real efforts to save the humanitarian disaster there.

Hassan, the displaced: Instead of telling us they will build a port to help us, stop supplying weapons to Israel, all those weapons from the United States are killing us and our children anytime and anywhere.

What Are the Differences between Cold Heading and Cold Extrusion

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.After that, non standard fasteners Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://jieruifasteners.com/

　　

　　1. What is cold extrusion

　　

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　

　　

　　2. What is cold heading

　　

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　

　　3. Are cold heading and cold extrusion the same thing?

　　

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).

What Are the Methods to Prevent Loosening of Anti-loosening Nuts

　　Anti-loosening nut is a nut, which is a part that is screwed together with a bolt or a screw for tightening. It is an original part required by all production and processing equipment. Anti-loosening non standard nut is a part that tightly connects mechanical equipment together. With the help of the inner thread, anti-loosening nuts and screws of the same specifications can be connected together. The following is a detailed introduction to several methods of preventing anti-loosening nuts from slipping.In the industry, non standard fasteners Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. https://jieruifasteners.com/

　　

　　1. Anti-loosening of equipment

　　

　　It is to use the locking nut stopper to directly limit the relative rotation of the locking nut pair. For example, the use of tooth pins, serial wires and stop washers. Because the locking nut stopper does not have a pre-tightening force, the anti-loosening stopper can only work when the locking nut is loose and returned to the stop position. Therefore, the locking nut method does not actually prevent loosening but prevents falling.

　　

　　2. Riveting and anti-loosening

　　

　　After tightening, use punching, welding, bonding and other methods to make the locking nut pair lose the performance of the kinematic pair and the connection becomes an irremovable connection. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be damaged before it can be disassembled.

　　

　　3. Friction anti-loosening

　　

　　It is the most widely used anti-loosening method. This method forms a positive pressure between the locking nut pairs that does not change with the external force, so as to form a friction force that can prevent the relative rotation of the locking nut pairs. This positive pressure can be achieved by axially or simultaneously pressing the locking nut pairs in two directions. For example, elastic washers, double nuts, self-locking nuts and insert locking nuts are used.

　　

　　

　　4. Structural anti-loosening

　　

　　It is to apply the locking nut pair’s own structure, that is, the Tang’s locking nut anti-loosening method.

　　

　　

　　5. Punching edge anti-loosening

　　

　　After the nut is tightened, the thread is destroyed by punching the end of the thread; bonding anti-loosening generally uses anaerobic adhesive to apply to the thread screw surface. After tightening the anti-loosening nut, the adhesive can solidify by itself, and the actual anti-loosening effect is better. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be destroyed before it can be disassembled.
