a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Some anaerobic archaea live on substrates that do not allow the synthesis of 1 mol of ATP per mol of substrate. Energy conservation in these cases is only possible by a chemiosmotic mechanism that involves the generation of an electrochemical ion gradient across the cytoplasmatic membrane that then drives ATP synthesis via an A1AO ATP synthase. The minimal amount of energy required is thus depe...
Nowadays required energy mostly comes from fossil fuels but the limitation of fossil resources and their environmental effects have encouraged communities to seek alternative renewable energy sources. Meanwhile enery forom biomass (bioenergy) has particular importance due to wide range of resources and other advantages. In this research, a multi-objective model is proposed to design a bioenergy...

this research is about the political economy of china in central asia. in this research the political & economic interactions affected on chinas political economy in central asia are examined. chinas goal of presence in central asia including political-security, economic and energy goals is described in one part. in another part, the trade relations between china and central asian countries ar...
Abstract Terrestrial ecosystems are essential for food and water security CO 2 uptake. Ecosystem function is dependent on the availability of soil moisture, yet it unclear how climate change will alter moisture limitation vegetation. Here we use an ecosystem index that distinguishes energy limitations in Earth system model simulations to show a widespread regime shift from between 1980 2100. Th...
Background: Since, energy consumption per square meter in hospitals is much higher than other types of service institutions; in this study, some actions performed toward optimizing energy consumption improvement projects based on the definition and prioritization in hospital. Materials and Methods: The necessity of optimizing energy consumption in hospitals were described according to so...
