AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

Abstract The evolution of the request in wood production leads to larger stem wood consumption, intensive harvesting and consequently the environmental impact increases. One of the most ignored secondary resources in spite of limited reserves, branch wood could be used in new added value products as an alternative to stem wood, providing its characteristics are known and understood. This paper is part of a larger research project, which here compares the compression strength parallel to the g...

Abstract Biofuels represent a possibility for renewable resources conversion, storage and distribution. Today, diesel oil is commercialized only blended with biodiesel, and according to the 30/2003 Directive of the EU, 5.75% of the total fuels used in the transportation sector must be represented by biofuels by the end of 2010. Biodiesel can be produced from vegetable oils, animal fats and used oils. Viscosity is one of the most important characteristics of liquid fuels. The viscosity of liqu...

AbstractWith a view to make a long term survey of the magnetic fields generated by the power line sources, appliances or, generally, by the low frequency magnetic field sources, a tri-axis magnetic field meter was proposed. Referring to the magnetic field sensor, both the characteristic proportional of the field strength and proportional to the time derivate of the field strength were considered. Thus, two active magnetic field meters working in 40 Hz ? 200 kHz frequency range were designed. In ...

Among the different types of waste products tested, the bark of different Pinus species have been identified as a promising class of low- cost sorbents for heavy metal binding. In this context, the potential of Romanian pine bark wastes as green and economical sorbent for cadmium (II) ions removal from aqueous solutions has been tested in batch conditions as function of initial pH, contact time, sorbent dose, metal ion concentration and temperature. The equilibrium data at three different temper...

Because the lifetime of methane in the atmosphere is relatively short, it could be kept under control. Wastewater treatment plants (WWTPs) are anthropogenic sources of CH4 emissions.

Abstract Soil organic carbon is one of the key substrates affecting methane emissions in paddy fields. However, not all soil organic carbon forms methane. This study therefore involved comparative analysis of the methanogenesis of different organic carbon sources (rice straw, chicken manure and pig manure) in paddy field soils. The results indicated that whereas methane emissions from the pig manure treatment (PM) were not significantly different to those associated with the application of c...

The shift from a linear economy to the circular economy emerges as a solution to save natural resources and to decrease the effects of the climate change on the environment. Understanding the role of the waste as secondary resource and recovering it can reduce the consumption of non-renewable primary resources, the consumption of energy in the production processes and can also lower the CO2 emissions. The study aims at evaluating the environmental impact when applying the principles of the ci...
