Abstract: With the growing need for alternative energy sources, research into energy harvesting technologies has increased considerably in recent years. The particular case of energy harvesting on road pavements is a very recent area of research. This paper deals with the development of energy harvesting technologies for road pavements, identifies the technologies that have being studied and developed, examines how such technologies can be divided in different classes and gives a technical analysis and comparison of those technologies, using the results achieved with prototypes

Abstract: One of the most widespread environmental problems is petroleum hydrocarbons contamination in soil and groundwater environments. Among the components of petroleum hydrocarbons, n-alkanes constitutes highest proportion and are the most readily biodegraded components. Bioremediation is a low cost and environmentally friendly technology in order to cleanup soil and groundwater contamination. Nutrient enhancement of bioremediation with nitrogen and phosphorus is called “biostimulation”, and increases process performance. Especially nitrogen is the most important nutrient for the hydrocarbon bioremediation due to the elevated carbon concentrations compared to nitrogen in petroleum contaminated soils. Many researchers have investigated optimum nitrogen levels in order to enhance bioremediation. However there is a limited number of studies on the effects of different nitrogen sources on n-alkane biodegradation in soil. In this study, it is aimed to reveal the effects of different nitrogen sour
