The World Firefighters Games is an internationally prominent sporting event that was found as an alternative to the World police & fire games. It was setup by an American entrepreneur and a group of international firefighters.

This was started keeping in mind the welfare of all firefighters and not just an individual. Based on this a non profit organization called World Firefighters Games WA Inc was started which was volunteered by employees and retired staff of the fire force.

To participate in the game Yohan Cabaye France Jersey , the eligibility criteria are to be a full time employee of industrial and military fire service who is a volunteer with the organization. This included retired firefighters as well as full time employees of a Fire department or brigade. Spouses of eligible participate also could take part in certain event. All participants must be above 18 years of age.

These games promote health and fitness to the volunteers, provides a platform for information exchange between the members, encourages positive relationship between the firefighters and also encourages their family members to participate in the events.

The World Firefighters Games is quite like Olympics but on a much smaller level. It contests a number of events that emphasizes the role of a firefighter Steve Mandanda France Jersey , and the critical and urgent nature of his work. This takes place every two years in different parts of the world. This being a non profit organization, the profits made by the host country is donated to some charitable institutes.

There are a vast range of games that takes place in this event which are common. Besides those, there could be particular events based on the host country?s traditions and probably their national games. Nevertheless Samuel Umtiti France Jersey , invariably the main attraction is always the enchanting ?Toughest Firefighter Alive? competition. This is specifically a World Firefighters Games based event inorder to find out who is the toughest, bravest and most daring firefighter of the lot.

The Toughest Firefighter Alive or TFA event is carried out in full firefighting Kit and tests competitors in a number of firefighting related disciplines. It is considered to be the most challenging game.

There are four parts to this TFA competition. One of it is the Hose run. This is performed with full firefighting kit and carrying a breathing apparatus where the competitors are tested in running the hose and also carrying it. Second part of the competition is the obstacle course which is also in full firefighter gear where the participants carry different parts of the equipments while fighting walls and tunnels which are placed before them as obstacles. Tower is the third part in this category where the competitors have to carry the firefighting equipments up using ropes. In the last part of the competition called the stair climb, the competitors climb to the top of the tower Raphael Varane France Jersey , the height of which could be between 100m 200m.

This extraordinary event decides who would be the Toughest Firefighter Alive, and the winner will be crowned with this title, which is indeed an achievement.
Comparison Between Dry And Wet Process For Sapphire Etching Comparison Between Dry And Wet Process For Sapphire Etching December 15 Paul Pogba France Jersey , 2013 | Author: Paul Drake | Posted in Business

Dry and Wet Etching are two popular processes that are being used for the production of patterned sapphire substrate. Having said that, it makes sense to understand the difference between the two so that you can determine which particular process suits best to your unique needs. So, I have prepared below some sort of comparison between the two processes.

Dry etching

- the most popular method used by manufacturing companies to etch sapphire substrates and it has a very slow process with a low throughput rate;

- Etching a standard 2-inch wafer can take between 30 and 60 minutes;

- experts say that it does not scale effectively; as wafer size increases Patrice Evra France Jersey , throughput of a dry etcher falls because fewer wafers fit inside the vacuum chamber. This results to the use of more expensive plasma etching tools to attain the same throughput as achieved using smaller wafers;

- as an estimate, dry etching rates range between 50nm and 200nm per minute is attainable;

- dry etching creates bright and efficient LEDs but the process takes it so slow and limited throughput.

Wet etching

- it has the advantage of being an extremely fast process and it can be carried out in a lot cheaper procedure than dry etching;

- the LEDs that are produced using wet etching process are not as efficient and effective as that of the dry etching process; however, it is very scalable.

- wet etching process provides a cost-saving advantage compared to dry etching;

- polishing touch-up work is performed on the wafers in order to increase light extraction efficiency.

Sample of equipment utilized in sapphire etching process:

The Accubath Xe-Series — designed to perform a wet etching process; this etching bath equipment has been proven to be a great help for semiconductor manufacturers as it helps improve the processes that were previously thought to be too slow due to temperature limitations. This equipment is developed by Imtec Acculine.

Hitachi High-tech Silicon Etch System — this equipment is capable of generating a stable high density plasma at a very low pressure; it is utilized in dry etching based on an ECR (*1) plasma source.

CDE-80N Chemical Dry Etching Equipment — used chemical dry etching process for thin film in a gaseous state semiconductor process. Damage-free etching process Olivier Giroud France Jersey , through perfect separation of the etching unit and plasma generating unit, enables wide use in the damage removal process.

Each of the etching processes discussed above has its own advantages. Cheap MLB Jerseys   Cheap Jerseys   Cheap Jerseys China   Cheap Jerseys China   Wholesale Jerseys China   Wholesale Jerseys China   Wholesale Soccer Jerseys   Cheap Jerseys China   Cheap NFL Jerseys   Wholesale Jerseys China
