Metal Speciation Studies in a Brakish/Marine Interface System


Scoullos M. J. and Pavlidou A. S.


The paper presents some interesting results of metal speciation studies employing Anodic Stripping Voltammetry (ASV) applied in a dynamic natural system such as the brakish – marine interface formed between the polluted waters discharged by the Koumoundouros lake and the marine ones of the Gulf of...

Observations of the directional spectrum relaxation of wavefields in slowly and rapidly turning winds


Tsanis I.K. and Brisette F.


A so called “Exact Form” of the Maximum Likelihood Method is used to obtain directional spectrum estimates from a 3-meter NDBC discus buoy, part of the Surface Wave Dynamics Experiment (SWADE) field array. The method was used to look at the response of wavefields to turning winds with various wind...

Neural Networks for Environmental Problems: Data Quality Control and Air Pollution Nowcasting


Benvenuto F. and Marani A.


This work illustrates the use and some related results of Artificial Neural Networks (ANNs) for data quality control of environmental time series and for reconstruction of missing data. ANNs are applied to the following problems: i) short and medium-term predicting of air pollutant concentrations in...

Management of Resources for Sustainable Development: Entropy "SHOWS" the way


Tassios D.


The purpose of “Sustainable Development” raises the following basic question: Which “indicator” should be used to identify the human activities that are contrary to this purpose? In this paper it will be shown that “Entropy Generation” constitutes this Indicator. To this purpose, we will use three...

Sustainability and regional development: the case of the tourism sector in Southern Europe


Modinos M.


The present work argues that sustainable tourism is essential to the long-term survival of the tourism industry in Europe. Sustainable tourism may be regarded as a means of redressing economic imbalances between European regions and nations without producing adverse environmental, social and...

Central Composite Design in a Refinery’s Wastewater Treatment by Air Flotation


Rigas F., Panteleos P. and Laoudis C.


Water resulting from the dewatering process of petroleum storage tanks was treated in a pilot separator to investigate the effectiveness of the combined action of a coagulant (aluminum sulfate) and a cationic flocculant (NALCO 71403). Central composite design of experiments was used to construct...

Application and Verification of a three-dimensional Hydrodynamic Model to Hamilton Harbour, Canada


Tsanis I.K. and Jian Wu


A multi-layered three-dimensional hydrodynamic model has been developed to provide flow fields and water level changes in Hamilton Harbour. The field data collected in Hamilton Harbour during 1990 & 1991 field seasons was used for model verification. The simulated currents were compared with current...

Electric field control of NOx formation in the flame channel flows


Zake M., Turlajs D. and Purmals M.


The present studies aimed to obtain clean fuel combustion and get detailed information about the processes that determine the electric field effect on NOx formation in flame channel flows. The experimental studies demonstrate that the interaction between the radial electric field and the flame...

Effects of wildfire suppression chemicals on people and the environment


Kalabokidis K.D.


Fire agencies worldwide apply millions of gallons of fire suppression chemicals on a broad array of ecosystems. These chemicals are considered to have minimal effects on the health of people who might be exposed to them. Only incidents of skin and eye irritation have been reported as a result of...
