Every year about 15 million people are injured in traffic, 500,000 of these fatally. Developing countries are badly affected. During the worst years of the war in Nicaragua, more people died in traffic accidents than as a direct result of the war. Transport system and infrastructure have developed rapidly in developing countries, while little has been achieved in preventing accidents or lessening
In this note the objectives of a project financed from European Community in the FP7 to realize a cleaning system for a syngas obtained from the gasification of biomass will be reported. In order to us the obtained sysngas can be transformed with further catalytic processes previously eliminating sulphur chlorine, COS, HCN NH3 and tars.
Choosing the right mortar for the job, and applying it correctly, gives a strong structure requiring less maintenance. A common problem is using too much cement in the mix, which is unnecessarily expensive and has technical disadvantages. Another common problem is using too thick a layer of rendering, which increases the risk of flaking and cracking. A masonry wall must meet several requirements
The pathloss exponent and the variance of the large-scale fading are two parameters that are of great importance when modeling or characterizing wireless propagation channels. The pathloss is typically modeled using a single-slope log-distance power law model, whereas the large-scale fading is modeled using a log-normal distribution. In practice, the received signal is affected by noise and it mig
