Excessive Noise

The development of urban transport in recent years has become one of the most important issues related to improving the quality of life in Polish cities. Excessive pollution in the form of greenhouse gases and other harmful substances from buses affects people’s health as does the excessive noise. This article analysed the measures being taken to reduce emissions, and the results showed that it is possible to reduce CO2 emissions by more than 28 thousand megagrams (Mg) per annum. Policymakers in Poland should consider limiting electricity generation through coal combustion and recognize, at least temporarily, CNG/LNG-powered buses as low-carbon rolling stock and co-finance their purchase and the necessary infrastructure.

The paper describes the results of a research programme, carried out at the Department of Aerospace Engineering of the University of Pisa, for the assessment of the influence of plasma cutting on the physical and mechanical properties of Fe510 D1, a low carbon steel widely used in carpentry. The activity started by observing that several industries rework plasma cut edges, particularly in the case of fatigue structures, in spite of the good quality of the plasma cut edges in a fully automatic process. Obviously, reworking is very expensive and time-consuming. Comparative fatigue tests demonstrated that the fatigue resistance of plasma cut specimens in Fe510 steel was fully comparable to that of milled specimens, as the consequence of the beneficial residual stresses which formed in the plasma cut edges.
