cities are a focal point of energy consumption. accessibility to public services has a significant impact on the balance of public and private energy uses, which are two sectors that are directly affected by urban planning (the third is industrial). this paper establishes the relative magnitudes of service accessibility enhancement on urban energy efficiency in comparison to other factors, and ...

Chemical denaturation and thermal denaturation of13-lactoglobulin A (f3 — lgA) in the absenceand presence of various concentrations sugar osmolytes and polyols were measured bymonitoring changes in the absorption coefficients at pH 2.0. It has been observed that AGD°(H20), (Gibbs free energy change in absence of denaturant at 25 °C) of f3-1gA in the presenceof 10% (w/v) Trehalose, Sucrose, Sorb...

Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the nig...

This present research work was carried out to evaluate the energy consumption in a typical Iranian building based on the forecast of climatic variables. Thus, the LARS-WG model was validated for some northwest stations of Iran, including Tabriz, Ardebil, Oromieh, Kermanshah, Hamedan, Sannandaj, Qazvin, and Zanjan. The average monthly outdoor temperature was forecasted from 2011 to 2100. The rel...

concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...

This paper studies the effects of a tax on energy use in a growth model where market structure is endogenous and jointly determined with the rate of technological change. Because this economy does not exhibit the scale effect (a positive relation between TFP growth and aggregate R&D), the tax has no effect on the steady-state growth rate. It has, however, important transitional effects that giv...

Iran has suffered ever-increasing domestic energy consumption, mostly because of its long-standing price control policy. To decelerate this trend, Iran began a reform on its energy subsidy system in December 2010. This paper examines the inflationary impact of the energy subsidy reform on different Iranian non-energy sectors and urban and rural households by making an updated input–output...

the density of state and the natural bond orbital calculations were carried out to study theoxidation of co on au14 nano cluster through two different mechanisms and determining the bestmechanism for the reaction. chemisorption of o2 and co on the nano cluster led to change in energy,density of state and its thermodynamic properties. we calculated the energy band gap between thehighest occupied...
