warming and cause many climate problems (National Atmospheric Emissions Inventory‚ 2008). One of the major greenhouse gases is carbon dioxide (CO2)‚ and the major emissions of CO2 are come from the combustion of fossil fuels in power generation‚ transport and industrial sectors (Figure 1). In order to have a better understanding of this issue‚ the first step is to analyze how many CO2 we have emitted in our daily life.

Research Investigation Safety features in cars Air Bags Air bags are safety features installed in cars so that upon collision the driver limits the damage that is inflicted on him/her. There are several different types of air bags. These include‚ Supplementary Restraint System (SRS)‚ an Air Cushion Restraint System (ACRS) and the Supplemental Inflatable Restraint (SIR). Air bags are commonly known for their rapid inflation upon a collision. They can inflate and deflate within 0.05 seconds
