The current transition to a greener economy affects world markets dynamics. Given the considerable hydrocarbon dependency, we scrutinise the resilience of the Russian fiscal stance to international oil and gas prices at the first phase of this study. In doing so, we apply Cross-Quantilogram and Dynamic Simulated Autoregressive Distributed Lags (DSARDL) to analyse time-series data from January 2011 to August 2021. Our investigation demonstrates the fiscal stance (FS) positively responds to positive oil price shocks at medium quantile of FS and at lower to the higher quantile of oil price. The degree of responsiveness of FS to oil price is profound in the medium memory due to the time lag of... 

Considering the dramatic increase of greenhouse gases concentration in the atmosphere, especially carbon dioxide, reduction of these gases seems necessary to combat global warming. Fossil fuel power plants are one of the main sources of CO2 emission and several methods are under development to capture CO2 from power plants. In this paper, CO2 capture from a natural gas fired steam cycle power plant using oxyfuel combustion technology is studied. Oxy-fuel combustion is an interesting option since CO2 concentration in the flue gas is highly increased. The Integrated Environmental Control Model (IECM) developed by Carnegie Mellon University (USA) is used to evaluate the effect of this capture...
