A Versatile Gentleman aims to do justice to Plutarch's versatility by discussing the Chaeronean from many different angles. As such, it sheds new light on the coherence of, and the tensions in, Plutarch's thinking and writing.
One of the key problems of failure-free operation of machinery is prevention of corrosion. The global scale of modern production makes this problem even more critical. At the beginning of the 21st century industrial contami- tion and the corrosion-active nature of the environment reached a level such that corrosive damage of materials became commensurate with their prod- tion volume and expenditure on anticorrosion protection of machines became comparable with investments in basic production. Anticorrosion techniques changed from being an auxiliary service to industrial enterprises into a dev- oping, scienti?cally intensive and generously ?nanced branch of production. Polymers occupy a very speci?c place amongst anticorrosion techniques. Polymers combine good chemical resistance with impermeability to di?- ent media and unusual deformation characteristics. The main principle of their application as anticorrosion means is the creation of a tight barrier that insulates metal machine parts or constructions from corrosion agents. The advantages of polymers allow the creation of such a barrier at minimal cost, providingprotectionoftheworkingmachinesfromcorrosion, combining their manufacture with preservation and decreasing the cost of anticorrosion. This is one of the main reasons why world production of polymer materials increased by almost 50% in the past decad
