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...

AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

AbstractThe objective of the paper is to present sustainability indicators for municipal solid waste management (MSWM). Sustainability implies environmental, economic and social acceptance. The complexity of the system-in-focus requires the employment of a systems (or cybernetic) approach: Acceptance implies clear objectives, from a specific point of view (here, the viewpoint of the municipal administration is taken), over a time horizon covering at least two generations, a life-cycle considerat...

AbstractOne of the basic principles in the European policy to cope with the growing challenge of water scarcity is that water demand management should be considered before opting for additional water infrastructure. The implication of this is that water must be treated as an economic good, which means that the "user's pays' principle"has to be implemented. At the same time there is much political consensus that the water price has to be "equitable". Water can be subsidized without violating the ...

AbstractThe paper reports experimental refractive indices of binary systems iso-propanol - water and iso-propanol - toluene over the entire range of composition at different temperature. Excess refractive indices were evaluated from the experimental data obtained. This derived property was fitted to variable-degree polynomials. The results obtained have been discussed and interpreted in terms of the type and nature of the specific intermolecular interactions between the components....

AbstractThe cost sensitivity analysis of a chemical process was carried out through a sequence of three stages, using three different software applications. In the first stage an alkylation process was optimized with GAMSÂŽ software, the objective function being the profit. This optimization was repeated for the values of five different costs in the frame of a factorial experiment. In the next stage, the objective function-costs dependence was quantified with an artificial neural network, obtain...

AbstractEnvironmental pollution has posed and continues to cause specific to and complicated problems. The unsustainable production and consumption patterns result in waste that can harm health and the environment. Because of rapid population growth and urbanization, industrialization process and rural to urban migration, solid waste management is becoming more and more critical now, being a problem in rapidly growing urban centers in developing countries. All these threaten the health and well-...

Abstract This work investigated the sorption removal of chromate anion, in single batch systems, from aqueous solutions. The process involves the sorption of the chromate by a series of Mg/Zn-Al - type hydrotalcites, with four Mg/Zn/Al ratios, in two forms: uncalcined and calcined at 500 °C. The calcined Mg-Al (Mg/Zn/Al = 2/0/1) material showed the highest sorption capacity: 35.7 mg/g. The three-parametered Langmuir-Freundlich model approximated the experimental equilibrium data over the con...

Abstract Increasing the solar energy conversion into electrical or thermal energy represents an European and national priority, because it offers clean alternatives to the use of fossil fuels, in no pollutant systems, based on photovoltaic modules and solar collectors. The global solar radiation is the most important factor affecting the amount of energy produced by a PV module. In direct connection with the change in the solar energy conversion, the TR - Loss Coefficient (Tr??bungsfaktor) is...

Abstract The Aries River, due to its geographic position and its significance in the Mures - Tisza Basin, has a major impact on environmental media, influencing their quality. In the Middle Catchment Basin the main industrial activity is mining, since the Roman times, when the first mines were opened. The mining operations in the region generated a severe pollution of all the environmental media. The paper identifies the risk areas in the middle Aries River in terms of surface water pollutio...

This paper presents a mathematical model for the prediction of pollutant transport in rivers. The model has been developed and calibrated using the Matlab software and relying on field data from Romanian Someş River (collected in case of accidental cyanide release). Field data has been used to estimate model parameters (e.g. dispersion coefficient, velocity) as variable in time and space in order account for river features non-uniformity in time and also in space. These initial parameter va...

Infrasound is a sound wave with a range of frequencies below that of human hearing and is a constituent of the environment in which we live. Taking into consideration that infrasound is below the audible range and that its overall effects on the entire human organism are yet unknown, the ambiguity of the phenomenon requires further research. Although infrasound has been analyzed in depth in the past few decades and assumptions have been made regarding experiments on human subjects (with or witho...

The synthesis of vanadium oxide systems (with 5 and 20 wt% V2O5 loadings) supported on commercial γ-alumina was carried out by a wet impregnation method. The samples were characterized by low-temperature nitrogen adsorption (BET), inductively coupled plasma (ICP) method and by in situ electrical conductance/capacitance measurements. The adsorption of CO was used to investigate the acidic properties of alumina support and V2O5/-Al2O3 catalysts by FTIR spectroscopy. The catalytic acti...

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.

AbstractThe inactivation of Escherichia coli was investigated with two types of underwater electrical discharge systems such as pulsedelectrical discharge (PED) and dielectric barrier discharge (DBD). The DBD system consisted of a quartz tube and a coaxialdischarging electrode, which was submerged in biologically contaminated water. In the underwater PED system, the electricaldischarge starting from the tip of submerged tubular discharging electrode propagated downward and the direction of worki...

AbstractChina’s natural wetlands occupy 3.77% of the land and provide 54.9% of China’s ecosystem services. Healthy natural wetland ecosystems play an important role in the sustainable development of China, which was realized by the Chinese government in the early 1970s. In the past 5 years, China has made great efforts in wetlands conservation, which is signified by the funding of billions of dollars to restore degraded wetlands, the policy to return reclaimed croplands to wetlands, the specific...

AbstractIn European countries with temperate climates, heating represents approximately 70% of the total energy consumption of aresidential building. Different Directives of the European Parliament and Council prescribe the enhancement of energy efficiencyand the reduction of energy demand of buildings. Consequently, the control of delivered heat is indispensable. The properoperation of the control system is possible only for balanced central heating systems. In the case of central heating syste...
