Determining the phenological stages of Nestos-Delta (Alnus glutinosa) riparian forest (Natura 2000 site) by using radiation transmittance data

(Corresponding) Proutsos N., Karetsos G., Tsagari C.
Topic: 
Environmental data analysis and modelling
Trees’ phenology is a key factor for most forests’ physiological processes. The precise definition of the start-end dates and the duration of each phenological stage is critical. In the present study, radiation data were used from pyranometers installed at the Alnus glutinosa riparian forest of...Read more

The development of a Forest Canopy Density (FCD) model in Akamas National Forest Park in Cyprus, using Landsat-8 and Sentinel-2 satellite data

(Corresponding) Prodromou M., Danezis C., Gitas I., Hadjimitsis D.
Topic: 
Disaster risk reduction and management
The canopy of trees plays a very important role in forest ecosystems and acts as a regulator, affecting the microclimate and the soil conditions. The density of the forest canopy is associated to the forest development and it can be used as an indicator of forest degradation. Additionally, forest...Read more

Thornthwaite's approach for assessing aridity changes during the last seven decades in the urban environment of Heraklion-Crete in Greece

(Corresponding) Proutsos N., Bourletsikas A., Solomou A., Tsagari K.
Topic: 
Atmospheric chemistry and physics
Changes in aridity, especially to more arid classes, can have a strong impact on vegetation development in urban environments affecting also the inhabitants’ health and quality of life. In this work, water related parameters (i.e. Potential evapotranspiration PET, water deficit D and surplus S) and...Read more

Production and characterization of microalgal biomass from dairy wastewater

Iliopoulou A., Zkeri E., Panara A., Dasenaki M., Aloupi M., Fountoulakis M., Thomaidis N., (Corresponding) Stasinakis A.
Topic: 
Environmental biotechnology and bioenergy
During the last decade, a large scientific effort has been directed towards the cultivation of microalgae in dairy wastewater. Among different microalgal species, Chlorella sorokiniana is a small, fast-growing, robust microalgae that can be grown under mixotrophic conditions. In the current study,...Read more

Role of microplastics as vector for pharmaceuticals in aquatic environment

(Corresponding) Papac J., Kovačić M., Katančić Z., Kušić H., Hrnjak Murgić Z., Lončarić Božić A., Karamanis P.
Topic: 
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The presence of contaminants of emerging concern (CECs) in aquatic environment represents the risk due to potential adverse effects on both human health and the environment. The term CECs does not only apply to chemical contaminants but to the microplastics (MPs) as well. As MP may interact with...Read more

Characterisation of Radioactive Contaminated Waste: Alpha-Induced Air-Fluorescence Detection Under Daylight Conditions

(Corresponding) Gamage K., Crompton A.
Topic: 
Hazardous waste management
Short travel of alpha particles in environments complicated the detection and characterisation of alpha-emitting contamination in mixed radiation fields in nuclear decommissioning sites. As a result, detection of alpha-induced radioluminescence became popular in nuclear decommissioning applications...Read more

Risk Evaluation of Community-Based Water Systems from Nonpoint-Source Pollution in Eastern Visayas, Philippines

(Corresponding) GOMBA F., PERANTE W.
Topic: 
Hydrology and water resources
This study evaluated the risk posed by nonpoint-source (NPS) pollution to the 266 community-based water systems (CBWS) in Eastern Visayas, Philippines. Geographic Information System (GIS) techniques, together with Multi-Criteria Decision Analysis (MCDA) was used to develop a Nonpoint-Source...Read more

Effect of current density value and current application period on the wastewater treatment performance of Electrochemically Enhanced Self-Forming Dynamic Membrane Bioreactors (e-SFDMBRs)

(Corresponding) Almalvez J., Morales-Corpuz M., Borea L., Castrogiovanni F., Napodano P., Belgiorno V., Naddeo V., Ballesteros F.
Topic: 
Wastewater treatment
The use of membrane reactor in wastewater treatment gained interest for the past years due to its high-quality effluent. However, expensive membranes and high operational costs due to membrane fouling limit the wide application of this process. Research on fouling control by combining membrane use...Read more

Prior electro-mechanical separation to improve metal recovery from ceramic-rich electronic waste using bioleaching

(Corresponding) Baniasadi M., Ray D., Graves J., Bolton R., Renshaw D., (Corresponding) Farnaud S.
Topic: 
Solid waste management
PCBs, as one of the most valuable streams of e-waste, are a considerable source of precious metals, but also contain considerable amounts of plastic and ceramic. These non-metallic fractions interfere with and can inhibit the efficiency of metal recovery, particularly for precious and rare earth...Read more

Gas mixture candidates for SF6 replacement in medium voltage switchgear: Analysis and modeling of the filling episodes

(Corresponding) Espinazo A., Lombraña J., Alonso M., Alonso R., Izcara J., Izagirre J., Pereda-Ayo B.
Topic: 
Energy technologies and sustainability
A more environmentally friendly replacement for SF6 must be found for medium voltage switchgear, as a change in European regulations will come into force soon. The mixing process of alternative binary and ternary gas mixtures is studied, which are made up of the hydrofluoroolefin HFO-1336mzz(E) (...Read more
