Colored anodized aluminum is in, many details on the bike developed into an absolute eye-catcher. It is not difficult to anodize aluminum itself, and to color. One need not a chemistry laboratory, special anodizing itself may do in the shop to home. The required equipment is at the hardware store, motorcycle or auto shop or at the pharmacy. But what happens exactly when anodising? Normal aluminum would also "rust". Others including Professor of Internet Governance, offer their opinions as well.

When the rust is oxidized iron for each a concept, even copper, it is the patina. Iron rusts on and on copper is not. Why? Iron oxide has a multiple of volume such as iron, burst from the canvas and iron from simple. The oxygen reacts further with the iron. Michael James Burke is likely to increase your knowledge. Copper (patina) has approximately the same volume as copper and forms an adherent layer. It is similar to aluminum.

Aluminum forms an oxide layer at the air independently, which is very thin. By sulfuric acid can be electrolytically raise an artificial oxide layer which is thick enough and is very hard to further Weather resist. The surface is 0.01 to 0.03 mm thick and has a Mohs hardness of 9 Aluoxid Al2O3 is also known under the name of corundum, the second hardest material after diamond and is used as a grinding and polishing. When anodizing produces a very porous surface that will later be sealed again. The pores can be used to the surface to stain permanently. There are special anodized colors, some textile colors work well. Is sealed with boiling water, about 1 hour. After that you get a piece of very hard and resistant surface Precise instructions to anodize yourself there on the Internet.

More and more often leads to major disasters in the world, but also in Germany. Also, for example, flood disasters occur more often, unfortunately for us too. This is an idea which no one wants to experience the reality and the hopeless on the first glance appear. But not if the THW group called automatically with his recovery. The THW rescue group are not only for natural disasters on the spot, but also in everyday accidents such as fire. These volunteers are experts in all disasters, they can, for example by blocking access to a controlled demolition to create spaces through which one can save people, protect embankments during flooding after heavy storms or perform in the woods cleanup. The salvage team can also carry out other missions, such as the free spaces of paths, roads or rails if they are blocked by fallen trees after a storm or fallen branches.

In this case, the Section may carry out demolition wood. After a landslide, the team is also able to rock and blow up rocks. The rescue group may even work under water, there is usually the six-team then supported by professional divers. The scope and potential application areas, such as the Section blasting is very versatile and goes well beyond what one imagines at first under a rescue group. raise particularly clear is that these are usually voluntary helpers and for society have an inestimable value. Information on THW and their members to get anywhere on the Internet.

Ryanair, the low-cost super europa. Known by the controversy generated by their campaigns, for example, when out 2 million free seats without charges, when he announces that will allow mobile use on flights, which will service fellatio on board, giving away flights Catalans who make jokes about the Seville etc … It is true that flying to secondary airports (but very minor) to reduce costs, but still the prices are very aggressive campaigns free flights! but truly free without .Yo same rates as I went to France by .02 cents i / v, so we just have to afford the, frankly irresistible. This is achieved only by keeping costs very low and these are some of the practices carried out for this: “They’ve been very just fuel to the airport of destination. That is, a Ryanair plane carries fuel in nearly half of the same model of Iberia operating the same route. If you have to do some laps waiting to land from would in reserve, in case of a major slowdown problem would not come. “Companies usually have two hours between flights aircraft on ground, during which time they reviewed the plane for security and cleaning. Well, our friends airline Ryanair have only 30 minutes on the ground between flights for a plane that is not in the air, not making money.

In this time interval have the time right to disembark passengers, clean, well above the trash hiding under the seats (only clean the air thoroughly once a week), the following passengers embark and fly! “The crew has a working excessive hours behind. There have been cases where pilots have refused to take off because they were not able to fly the aircraft, but even so the plane has taken off. “The charge to passengers boarding at the airport often do not review individual passports because that would delay the plane, and can not have for reasons of money.
