Framework Directive (2000/60/EC) (WFD) sets out a series of legal measures at European level against surface waters chemical pollution. The EU-list, annex of the WFD, contains those substances that present a significant risk to human health via aquatic environment, known as priority substances. In the last ten years, the Danube water quality has improved significantly. Instead, heavy metals concentrations in the tributaries waters sometimes were found to be rather highest and the chemical status is not in-line with the WFD requirements. Therefore, the Danube River Basin (DRB) waters quality showed a significant variability in terms of priority substances due to the diverse human activities, especially mining activities. This research paper aims to assess the chemical status of the DRB waters located on Romania territory regarding six heavy metals: Pb, Cd, Ni, Cr, Cu, and Zn by analysing water and sediment samples collected from different areas (south-west and north-west of Romania). Based on the obtained results by evaluating the quality elements, the water chemical status of DRB achieved a good chemical status for 74% of water samples and 55% of sediment samples. Also, the basic statistic and multivariate analysis were used to explore the relationship between the concentration values obtained for priority substances to underlying the water quality assessment.

In order to fulfil the latest EU emission standards, the average amount of CO2 emissions for each vehicle sold has to be reduced to avoid fines for manufacturers. One of the simplest and cheapest ways of hybridization is the belt starter generator (BSG), which makes it suitable for an entry-level range of vehicles. This paper presents a software strategy developed for internal combustion engine (ICE) and belt starter generator (BSG) control on a vehicle equipped with automated manual transmission and also the drivability, comfort and emission performances improvements expected by using this strategy.

An automatic braking system is an important future step in attending the autonomous vehicle. This system increases the active safety of a vehicle, significantly reducing road accidents, and lowering the effects of accidents. The paper will present the steps that will develop the autonomous braking systems in conformity with the Society of Automotive Engineers (SAE) from the USA. As well the paper will present the modelling and simulating of the automatic braking systems of a vehicle from the middle class using LMS Amesim software.
