The price elasticity of demand enables to set the real “correct price” to the seller guaranteeing the highest income. Despite the fact that the price elasticity of demand is very important in the economic practice, no work that would deal with it

A qualitative modelling philosophy has been developed in an effort to produce a general and reasonably unified common sense approach to the modelling of unique, complex and unsteady state systems. Economics, Ecology, Sociology and Politics are scienc

The initial mixture of magnetite with 20 vol.% of cerium carbonate is treated at 673 K and 1173 K leading to formation of Fe-oxide/cerium dioxide reactive sorbents. The main interest is devoted to iron-oxide composition and interactions between both

Purpose of the article: With the ever-increasing development of property prices and the disproportionate number of new housing developments, the question is which factors have an impact on this phenomenon from the-out-of-the-box perspective. For the

Cerium dioxide, which is diamagnetic in its bulk crystalline fluorite form, exhibits ferromagnetism when prepared as a nanopowder. This characteristic has recently been ascribed to localized electron spin moments formed at oxygen vacancies near the n
