Tungsten carbide nozzle plays a significant role in current industry, agriculture and manufacturing, which is widely used in cleaning, humidification, coating, fireproofing and hydraulic rock cracking, etc. Tungsten carbide extended nozzle can be specifically divided into long nozzle, medium nozzle and minute length nozzle, they are base on the common nozzle and enhance the impact energy of the flow so that it increases the volume of rock cracking and improves the drilling efficiency. Length, angle of flare, bottom pressure and safety is essential parameter to evaluate the quality of nozzle. And tungsten carbide extended nozzle makes a great progress in such aspects, which has sufficient impact energy, short distance to bottom and larger baric gradient. Therefore, tungsten carbide extended nozzle has better rushing and cleaning effects.

Because it has such a very high melting point and low vapor pressure, tungsten is used in high temperature situations. For instance, the filaments in light bulbs are made of tungsten. It is used in other applications in electronics as well.

When added to steel, tungsten increases its strength. It is alloyed (mixed with) other metals to make "superalloys" which have special physical properties of high strength and heat resistance. Some of the applications for such superalloys are in turbine engines for jet aircraft and energy generation.

Other alloys bearing tungsten are used for armaments, heat sinks, radiation shielding, weights and counterweights, wear-resistant parts and coatings.

Tungsten is the only material used to make light bulb filaments. Experiments are being done with ceramic and ceramics mixed with metals to create alternative cutting materials. Cemented carbide made with tungsten carbide is still preferred to these materials.

The Colombian government is preparing a raid to seize and close a major illegal tungsten mine run by the Revolutionary Armed Forces of Colombia (FARC), which is said to have supplied top multinational companies, including BMW, Volkswagen, Samsung and Apple.

According to Radio RCN (in Spanish), security forces are being deployed to an area of the Amazon jungle under the FARC’s control, known as Cerro Tigre, or Tiger Hill, in the eastern Guainía department.

Tungsten is a super-hard, heat-resistant metal that is used inside car engines, computer screens, phones, tablets, televisions, and also in the oil industry.

The planned raid on Tiger Hill comes on the hills of the European Union decision to impose tough laws to prevent businesses from buying gold and other minerals that fund the conflict in Colombia.

The Caribbean country is not alone. In the past few years illegal mining has spread through Latin America. Countries such as Peru, Ecuador, Venezuela, Bolivia and even Brazil, are currently said to be obtaining higher profits from the unlicensed activity than from drug trafficking, an illicit activity that used to generate profits in the area.

Now for the really weird part: If the player throws a dart into the area from the bulls-eye to the triple ring (bull and double bull included), the dart is left in the board and is a "PRISONER". A prisoner dart remains in the board until any player (including the player who threw the dart) hits the playable area of the same number (in the case of the bulls-eye, hitting another bulls-eye captures the prisoner). Once a player captures a "prisoner", the dart is his/hers to use for the rest of the game (unless it is lost in the same manner).

If there is more than one "prisoner" dart that may be captured, they may only be captured one at a time. For example, if there are two darts in the 18 between the bulls-eye and the triples ring, two darts must be thrown into the playable area of the 18 to capture them both.

After the first "prisoner" is captured, one player now has four darts to use while the player who lost the dart has only two. By the end of the game, you might be playing with 7 darts and none of them might actually be yours!

Play continues until one player has gotten a dart in every number from 1 through 20 in the target area. The first player to do this wins the game.

Strategy: The only strategy in this game evolves the decision to progress towards reaching the 20 as opposed to trying to capture prisoner darts. While "wasting" darts trying to get the prisoner darts, other players may get too far ahead of you and win the game. Remember keeping your original three darts is the best idea, other people darts do not throw the same as yours and you will not be as accurate.
