Part 3: The impact of crises on economic cycles As we have seen‚ economic cycles are dotted with crises. These crises are the causes of the imbalance of the system‚ and they also become a necessity in order to recover. Every great crisis has enabled the states to identify faults and defects of the economy‚ and they are indicative of system malfunction. Thus‚ States learn from their mistakes and make arrangements to avoid another crisis. This is called "purging" of the economic system. This

In the atmosphere was where I started. Seventy five years I was there. A carbon atom in a carbon dioxide molecule was what I was. A Pinyon pine tree going through photosynthesis took me from the atmosphere. After I left my home‚ I converted into a tissue in a Pinyon pine needle. This was only the first part of the cycle‚ and I was going to the biosphere-plant. A new territory‚ the biosphere-plant. Accordingly‚ I existed as a tissue in a Pinyon pine needle. For two months I stayed like that.

Carbon fibre-reinforced carbon (aka carbon–carbon‚ abbreviated C/C) is a composite material consisting of carbon fibre reinforcement in a matrix of graphite. It was developed for the nose cones of intercontinental ballistic missiles‚ and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter. It has been used in the brake systems of Formula One racing cars since 1976; carbon–carbon brake discs and pads are a standard component of Formula One brake

matches is red phosphorus. A chemical equation of lighting a match is: 16KCl3 + 3P4 S3 --> 16 KCl + 9SO2 Actually phosphorus is found in three main forms: white‚ red‚ and black. (There are also numerous allotropes of each of these forms.) White phosphorus is a soft‚ waxy‚ flammable substance‚ consisting of tetrahedral P4 molecules; it is often slightly yellowish because of the presence of impurities (hence‚ it is sometimes imaginatively known as yellow phosphorus). White phosphorus is highly
