“We unite and serve several disciplines - including airsoft, paintball, military, and law enforcement training - so we decided best way to serve our broad customer base is to allow them to trade in old equipment they already have for new.”

The pitch appears just in time for people who might be shopping for that wonderful gift either for himself or herself or a friend or family member. The end date for offer has yet to be established, Mr. Tran thinks that it will be a hit since it targets a customer base that have previously articulated their curiosity in real action games and training.

“We just want to make it easier for our customers to get newest and best products available.”

A specific case in which effects specified by Dalton's law should be seriously considered by divers is regarding nitrogen. Whenever there is an increase of partial pressure of nitrogen, this would cause a higher nitrogen concentration dissolved in diver's blood, and this could cause him to suffer a nitrogen narcosis. This, among many other situations which might arise due to facts stated by Dalton’s law, should be prevented by a proper planning of diving activities which a diver intends to practice.

The effects which a gas might cause on a diver are based on pressure which such gas exerts on his body. This explains why Dalton's law is so important for divers and why they should understand it and prevent effects it explains. Partial pressure related problems can affect human body in several ways, such as causing nitrogen narcosis or ear canal damage among others, and therefore divers should pay attention to these dangers and take necessary precautions.
