Ecological Economics And Transport Systems
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 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...

Evaluation of artificial neural network techniques for river flow forecasting
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 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 ... Autori: Cintia Bertacchi Uvo, Dimitri Namgaladze, George Gabitsinashvili ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25110

Municipal pricing of water considering that water is both an economic and a social good - a pricing reform with implications for Romania
Environmental Engineering and Management Journal › Vol. 6 › Nr. 5 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 ...

Literature data show that in general, plastics produced through the mechanical recycling route involve less carbon dioxide emission than when produced from crude oil. A review of readily available data shows that road transport of untreated waste plastics account for a significant portion of the carbon dioxide emission generated during recycling. Therefore, much carbon dioxide emission can be saved by optimizing the logistics in the recycling of plastics.

Assessment of the anthropogenic impact on water systems by fluorescence spectroscopy
Environmental Engineering and Management Journal › Vol. 8 › Nr. 6 Abstract
Organic matter is ubiquitous in every type of aquatic system and due to the influence that it has on their ecological health, can be used as a useful water quality indicator. Fluorescence spectroscopy has been efficiently used in the past decades to determine and characterize organic matter, and its link to function and chemical water quality.
In this paper, fluorescence fingerprints are presented in order to evidence the anthropogenic influence on different aquatic systems. Using f... Autori: Elfrida M. Carstea, Luminita Ghervase, Gabriela Pavelescu, Dan Savastru ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25576

Unlike the P. shermanii and S. cerevisiae cultures, the study on the distribution of oxygen transfer in stirred bioreactor for P. chrysogenum free mycelia broths indicated that this process is controlled mainly by the high apparent viscosity of broths, and less by the presence of fungus biomass. For this reason, the influence of fungus accumulation on the reduction of kla is attenuated compared with that obtained for bacterial or yeasts broths. The lower influence of fungus biomass i...
