Start-up of the nitrogen removal process in an anaerobic up-flow reactor inoculated with aeration tank sludge

Wijaya I., (Corresponding) Ribeiro H., Soedjono E., Slamet ., Teixeira C., Bordalo A.
Topic: 
Wastewater treatment
Anaerobic ammonium oxidation (anammox) has been considered a promisingly alternative to traditional nitrification/denitrification to remove nitrogen in an autotrophic process, without using an external carbon source, requiring low energy consumption and sludge production. The start-up of the...Read more

Radiation-induced degradation products of 2-methyl isoborneol and geosmin: the role of different reactive species

CHRISTOPHORIDIS C., PESTANA C., LAWTON L., (Corresponding) HISKIA A.
Topic: 
Water treatment
Gamma radiolysis can serve as an effective method for the degradation of organic water pollutants, due to the production of reactive species, oxidative (OH•, OOH•, O2•-) or reductive (eaq-, H•). The application of scavengers enables the selective production of these species. Our aim was to explore...Read more

The contribution of the cadaster to the protection of urban forests. The case study of Seich Sou.

(Corresponding) Vordoglou M., Samara T., Tsitsoni T.
Topic: 
Spatial environmental planning
This paper studies the way in which modern land-forest map design contributes to the protection of urban forests generally and the Seich Sou urban forest of Thessaloniki in particular. We also examine the role of cadaster and forest maps in protecting urban forests from abuses such as pressure for...Read more

IN-SITU REMOVAL OF ANTIBIOTICS IN SOIL BY COLD PLASMA

(Corresponding) Aggelopoulos C., Hatzisymeon M., Tataraki D., Rassias G.
Topic: 
Soil and groundwater contamination and remediation
Antibiotics are extensively used in clinical settings to treat or prevent human diseases, in veterinary science for farm and domestic animal health and in agriculture for crop protection. Due to their incomplete biological degradation, human and animal antibiotics are released through discharges...Read more

Design-based and model-based estimations of distribution and abundance of dolphin populations in Gulf of Corinth, Hellas

(Corresponding) Karamitros G., Giantsis I., Martsikalis P., Kavouras M., Exadactylos A.
Topic: 
Enviornmental data analysis and modelling
In recent years a major scientific effort has been focused on the protection of marine mammals. Gulf of Corinth is part of the Natura 2000 network (GR2530007) since 2016, with Special Areas of Conservation and constitutes an important habitat for striped dolphin (Stenella coeruleoalba), bottlenose...Read more

Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons

(Corresponding) Boycheva S., Zgureva D.
Topic: 
Climate change mitigation and adaptation
At present, the developments of sustainable carbon capture technologies are of the main scientific and technological priority required to mitigate the over generation of greenhouse gases. Three CO2 clean energy production approaches have been outlined: pre-combustion capture, oxy-fuel combustion...Read more

Lipid production by Rhodosporidium toruloides growing on media presenting composition similarities with the spent sulfite liquor in batch and fed-batch cultures

Michou S., Vastarouchaa E., Sarris D., Kalantzi O., (Corresponding) Papanikolaou S.
Topic: 
Environmental biotechnology and bioenergy
Aim of this study is to explore the effect of sodium lignosulfonate (SL), a paper industry by-product, on cell growth and lipid production by the yeast Rhodosporidium toruloides, cultivated on xylose-based media, that mimic the principal waste-stream originated from paper production facilities (viz...Read more

Odorous gases monitoring on industrial sites and algae decomposition using Cairsens smart sensors

(Corresponding) BEN DAOUD A., Laplagne J., AKIKI R., AFLALO S. S.
Topic: 
Environmental odour, monitoring and control
The appearance of natural odors sources (Sargassum beaching events) or odors generated by the human activity (integration of industrial sites in increasing urban environment and residential encroachment into previously non-resident areas) represent a major challenge for municipalities. Combined...Read more

Nitrogen co-doped with fluorine on reduced graphene oxide for enhanced electrocatalytic activity and stability for ORR in alkaline fuel cells

Musico Y., Labata M., (Corresponding) Chuang P., Ocon J.
Topic: 
Energy technologies and sustainability
Nitrogen co-doped with fluorine on reduced graphene oxide (rGO) was prepared by one-pot hydrothermal treatment method. The scanning electron microscopy (SEM) images and X-ray photoelectron microscopy (XPS) spectra revealed the successful doping of nitrogen and fluorine into the rGO. The Brunauer-...Read more

Biotechnological production of polyols through conversions of crude glycerol by newly isolated strains of the yeast Yarrowia lipolytica

Vastaroucha E., Michou S., Kalantzi O., (Corresponding) Papanikolaou S.
Topic: 
Environmental biotechnology and bioenergy
The purpose of this study is to investigate the ability of newly isolated Yarrowia lipolytica strains to grow on crude glycerol, the main by-product of the industrial production of biodiesel. In particular, the ability of the yeasts to metabolize glycerol and produce dry cell weight (DCW) and...Read more
