Development of GIS Based Method for Risk Assessment of Olive Mill Waste Water in Crete, Greece
Wastewater treatment
Water resources are subjected to different pollution sources. Point source water pollution of surface water is an important issue when considering the limited surface water availability as well as the potential knock-on effects of this pollution on human health as well as habitat and land...
Comparative assessment of heavy metals changes in the ambient air of two different zones of Tabriz City, Iran
Air Quality
Tabriz is a large and industrial city in the north west of Iran which suffers from severe air pollution due to being surrounded by mountains. Considering lack of official reports about the levels of heavy metals in Tabriz air, two zones of the city were selected for measurement of heavy metals in...
Adsorption of UV254 in Kerian River water onto ZeliacTM: Analysis using linear and non-linear forms of isotherm models
Water Resources Management
The composite media, Zeliac TM was developed with the initial aim to provide low cost adsorbent with promising adsorption capacity. This study was conducted to investigate the removal of UV absorbance at 254 nm (UV 254) in Kerian river water using Zeliac TM as the media. Batch experiments study was...
Modeling a Drought Index Using a Nonparametric Approach
General
Alternatively, to other studies that used parametric distributions (e.g. Gamma) in the estimation of the Standardized Precipitation Index (SPI), this study aims to apply a nonparametric method based on Kernel Density Estimator (KDE) for calculating the SPI. Results of the proposed method were...
A multi-stage methodology for selecting input variables in ANN forecasting of river flows
General
The scientific community has recognized the necessity for more efficiently selected inputs in artificial neural network models (ANNs) in river flows and has worked on this despite some shortcomings. Moreover, there is none or limited inclusion of ANN inputs coupled with atmospheric circulation under...
Evaluation of three pollutant dispersion models for the environmental assessment of a district in Kocaeli, Turkey
Air Quality
Air Quality Modeling is a method used to manage urban air quality. Various pollutant dispersion models are available, and each of these models is characterized by its own advantages and disadvantages. Thus, we aimed to evaluate the advantages and disadvantages of the models and to determine their...
The contribution of natural and artificial regeneration at the restoration of fire-affected peri-urban forest of Thessaloniki (Northern Greece)
General
In this study, the post-fire regeneration of three coniferous species ( Pinus brutia, Cupressus sempervirens and Cupressus arizonica) was examined in the peri-urban forest of Thessaloniki, Northern Greece. The wildfire took place in July 1997 and burned almost 60% of the forest vegetation. During...
Producing Hydrogen-rich Gas by Fresh Biomass Co-pyrolysis with Additive
Sustainable Energy
Pyrolysis properties of fresh ficus lacor leaves with moisture content of 70 wt. % was investigated in a TGA setup. The effects of different operating parameters on pyrolysis of biomass were studied in a fixed-bed reactor system. With addition of CaO, there showed an additional decrease in weight at...
Identifying the Quiet Areas of a Small Urban Setting: The Case of Mytilene
General
The aim of this study is to achieve a greater insight regarding quiet areas in agglomerations and contribute to their identification. The small urban setting of Mytilene located in the island of Lesvos (North Aegean, Greece), was the case study of this research. The need to control and manage...
Synthesis and application of CeO2/sawdust nanocomposite for removal of As (III) ions from aqueous solutions using a fixed bed column system
Wastewater treatment
In this study, nanocomposite of ceria sawdust (CeO 2/SD) synthesized by precipitation method was utilized for removal of As (III) ions from aqueous solutions. Study of the process was done in column system. Characterization of the nano sized adsorbent particles was carried out using XRD and SEM...
