Lighted Centers for Disease Control and Prevention (CDC) light traps were baited with carbon dioxide (CO2) produced from three different sources to compare the efficacy of each in collecting phlebotomine sand flies in Bahrif village, Aswan Governorate, Egypt. Treatments consisted of compressed CO2 gas released at a rate of 250 ml/min, 1.5 kg of dry ice (replaced daily) sublimating from an insul...

rigorous mathematical modeling of adsorption processes in packed beds involves time-consuming computations which are considered as the fundamental weakness of such thorough mathematical models. thus, reducing the computation time was a key factor in improving adsorption mathematical models. in order to achieve this goal, an attempt was made to know how much using different numerical methods inf...
In some last decades, increasing air pollution and its consequences captivate attention of researchers from all over the world. Scientists have developed some alternate fuels to eliminate the exhaust pollutants. In this paper, idea of using compressed air as a power source in natural gas engines is presented and discussed to explore the concept of new energy vehicles. However, energy densityof ...
The present paper explains the dynamics of substitution tensions between fossil energy carriers for gas consumption in the transportation sector of Iran in the horizon of 2025 using seasonal space model and Kalman filter approach for the years 2006-2019 in the form of quarterly data. Based on the results; Price elasticity and revenue elasticity of gasoline and gas oil are -0.20, -0.15, 0.27 and...
