Further restrictions on the use of compression-ignition engines in transportation are prompting search for adaptations to run other fuels. One most popular alternative fuels is Compressed Natural Gas (CNG), which due its low carbon content can be competitive with classical This paper presents results testing a Cummins 6BT compression ignition engine that has undergone numerous modifications con...

16 U.S. EPA priority polycyclic aromatic hydrocarbons (PAHs) were quantified in total suspended ambient particulate matter (TSPM) collected from an industrial site in Agra (India) using gas chromatography. The major industrial activities in Agra are foundries that previously used coal and coke as fuel in cupola furnaces. These foundries have now switched over to natural gas. In addition, use of...

The aim of this study is to clarify light scattering mechanism of hazy transparent cellulose nanopaper. Clear optical transparent nanopaper consists of 3-15 nm wide cellulose nanofibers, which are obtained by the full nanofibrillation of pulp fibers. At the clear transparent nanopaper with 40 μm thickness, their total transmittance are 89.3-91.5% and haze values are 4.9-11.7%. When the pulp fib...

the natural gas consumption in iran has been continuously increasing due to several reasons including low prices of natural gas, development of gas supply networks, people’s salary increase, incorrect consumption culture and the increase of national economy growth.  although, the global natural gas consumption has increased by 38% since 2001, the national consumption in iran has increased by 11...

A gas-gun technique to radially expand cylinders of a chosen material, based on a technique developed in 1979, has recently been re-established. Stainless steel 304 cylinders of length 160 mm, internal diameter 67 mm and thickness either 0.5 or 1.5 mm have been expanded using a 70 mm bore single-stage gas-gun. Microstructural analysis of the recovered specimens was performed using optical micro...
