Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...

Most theories of political economy operate in terms of what might be called separated political economy, as illustrated by the formulation: political economy = polity + economy. Within this formulation it is reasonable to speak of the state intervening into the market economy. In contrast to separated political economy, this paper explores some aspects of what might be called an entangled polit...

It is important to have a matching game within our program in order to match up the most compatible individuals. Similar individuals can have higher levels of trust at the start of the relationship and thus have lasting partnerships. However, we must also create a network structure that al...

Some “alternates within alternates” are studied and possible improvement of our energy policies are explored. The viability of a hydrogen fuel economy is reviewed. Methanol, ethanol or ammonia versus hydrogen is one area of interest. Others include liquid hydrogen versus jet fuels, the use of geothermal, solar, wind or water energy for production of hydrogen gas versus development of deep earth...

Knowledge is increasingly recognised as the key to determining competitiveness in the 21st century, emphasising the role of information, technology and learning in economic performance.

With more severe resource scarcity and environmental problems, the evaluation of circular economy in microcosmic level has become the focus of the academic world. Based on the concept of circular economy, this paper not only structures the evaluation index system of circular economy for iron and steel enterprises, builds the evaluation model of circular economy for iron and steel enterprises ba...
