Practice does not make perfect if your form is all wrong. There is a technique to throwing the perfect tungsten dart that will have to be utilized every single time. Your form and technique is what makes an accurate shot happen. The instructions of throwing a perfect tungsten dart are as followed:
Understanding the basics of throwing is very important. Your arm determines where the tungsten dart is going to hit and once you learn and perfect this, you will be able to hit where you want to every time.
The parabolic curve is how the tungsten dart will fly through the air. This is the same curve that bullets and baseballs fly on. Achieving this curve is by holding your arm straight out, bending it at the elbow. Keeping this form and holding it will lead to success.
With the tungsten dart in your hand, take aim at where you want it to go. Keep focusing on the spot you picked and not the dart itself. Once that is decided, make sure to keep your shoulder straight at all times. Release the tungsten dart, following through with your arm all of the way. When you start to throw, go slower and then gradually speed up.
Once you get the form down of how to throw the perfect tungsten dart, you will be doing it every time. Your technique will get better and better the more that it is used.
Trying to do tricks, like spinning or twisting the tungsten dart, will interfere with the parabolic curve and the tungsten dart will most likely not land where you intend for it to go.

Scram tungsten dart rule is a really fun game for two players that are played in two parts.
The Object: To score a higher score than your opponent after you've each had a turn as "scorer" and "stopper".
The Scoring: Each player throws one tungsten dart at bullseye, closest to the bullseye chooses to be the "stopper" or the "scorer". The "stopper" always goes first.
Players names are written in order across the top of the board with the numbers 1 through 20 and bullseyes written down the center of the board dividing the board into two columns.
The Play: The "stopper" plays first and throws three tungsten darts into different numbers. Each number that is hit is "stopped". Stopped numbers are shown by placing an X next to the numbers. Any part of the number may be hit to stop it.
After the stopper throws, the scorer now tries to score as high a score has possible with three tungsten darts. Any numbers that have been stopped, do not count towards a score. Any other numbers that have not been stopped count in the usual way. The thin inner "triples" ring counts as three times the number hit and the thin outer "doubles" ring counts as twice the number hit. Bullseyes count as 25 points and the double-bullseye counts as 50.
The scorer's score is kept as a running total and written on the scorer's side of the board. Once all the numbers and the bullseyes have been stopped, the round is over. The roles now reverse and the original stopper tries to score points while the original scorer stops numbers.Whoever has the higher total at the end of two rounds wins the game.
Strategy: Use your opponents strenghts and weaknesses against him/her. For example, I can't hit 18's to save my life but I can't be stopped on 16's and 19's. So, if you were playing me and new this, you should try to stop 19's and 16's first and let me flounder on the 18's all I want. Obviously it is important to try to stop the higher numbers first, though.

Extrusion is a process used to create objects of a fixed cross-sectional profile. The extrusion process is one important step to manufacture tungsten alloy radiation shielding. Tungsten alloy can be pushed or pulled through a die of the desired cross-section. The extrusion process may also increase the strength of tungsten alloy.
The process begins by heating the stock material (for hot or warm extrusion). It is then loaded into the container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterward the extrusion is stretched in order to straighten it. If better properties are required then it may be heat treated or cold worked. The extrusion ratio is defined as the starting cross-sectional area divided by the cross-sectional area of the final extrusion. One of the main advantages of the extrusion process is that this ratio can be very large while still producing quality parts.

Because tungsten for X-ray attenuation ability is used for all kinds of radioactive source shielding components or container of a kind of ideal material. In addition, tungsten is high density and environmental friendly. Tungsten is usually used to produce into tungsten radiation protective tank for industry and medical applications.
Tungsten radiation protective tank is used as medical tungsten radiation shielding for medical radiation shielding wall. Tungsten can be produced as needle radiation shielding for medical radioactive liquid shielding. Tungsten radiation protective tank can be used as cans, boxes and other containers used to store radioactive matter, collimator, for medical linear accelerator and nuclear technology applications in tungsten series test container system collimator, Co60 radiation shielding.Tungsten radiation protective tank can be used widely in industry, such as the radiation shielding for radiation detectors, and nuclear industry radiation protection. Tungsten radiation protective tank for shielding X-ray and gamma radiation can greatly enhance both the material properties and the shielding efficiency.

The chemical formular of ferrous tungstate is FeO4W and molecular weight is 303.6826g/mol. Besides the monoisotopic mass and exact mass is 303.865527g/mol, on the other hand, the PubChenm of it is 22178528.
Highly crystalline FeWO4 nanoparticles (NPs) were synthesized via the hydrothermal synthesis method while amorphous FeWO4 NPs were prepared by the room temperature precipitation method. It was found that a dissolution-recrystallization process appeared due to the Ostwald ripening when room temperature precipitates undergo the hydrothermal process. Photocatalytic performance toward the degradation of methylene blue showed that crystalline FeWO4 NPs displayed a higher activity than amorphous samples, mainly ascribing to the substantial elimination of defects after crystallization because the defects promoted the recombination of electron-hole pairs.
