Flood modelling using a combined 1D/2D model: the case of the 2017 flash flood in Mandra, Greece

(Corresponding) Mitsopoulos G., Bloutsos A., Diakakis M., Panagiotatou E., Lekkas E., Baltas E., Stamou A.
Topic: 
Climpact: national network for climate change and its impacts
The design of an efficient Early Warning System for floods in a specific region requires the knowledge of the hydrodynamic behavior of floods that affects flood arrival times and thus the available warning times. In the present work, we attempt to answer the following research question “Is a...Read more

Can mixed oxides act as efficient photocatalysts for the elimination of organic water pollutants?

(Corresponding) Favier L., Sescu A., (Corresponding) HARJA M., Siamer S., Lutic D.
Topic: 
Advanced oxidation processes
New mixed-metal oxides containing zinc and lanthanum were prepared by coprecipitation. The synthesized nanocomposites were calcined, and characterized by scanning electron microscopy (SEM), X-ray diffraction, FT-IR, BET and DR analysis. The calcined sample showed a higher crystalinity, confirmed by...Read more

Evaluating flooding impact to riverine bridges. The case of the Historical Bridge of Arta in Epirus, Greece

(Corresponding) Panagiotatou E., Mitsopoulos G., Stamou A.
Topic: 
Floods, droughts and water scarcity
ABSTRACT Climate impacts are expected to intensify weather related flooding events that are the most common and damaging natural disaster. Riverine bridges are particularly prone to failure during floods and their disruption may impair significantly flood evacuation plans. Thus, in the design of...Read more

Conversion of agro-industrial wastes into non-toxic protein-rich food additives by basidial fungi strains isolated from diverse ecosystems of Georgia

(Corresponding) Kvesitadze G., Tsiklauri N., Khvedelidze R., Kutateladze L., Sadunishvili T.
Topic: 
New solutions for a better and sustainable agriculture
Great interest to basidial fungi is determined by their potential to convert number of lignocellulosic wastes into nontoxic compounds, cheap food, pharmaceuticals, etc. The majority of basidial fungi strains are characterized by high activity of enzymes degrading plant biopolymers, including lignin...Read more

Groundwater Flow Dynamics in Shallow Coastal Plain Sands Aquifer, Abesan Area, Eastern Dahomey Basin, Southwestern Nigeria.

Joseph A.
Topic: 
Soil and groundwater contamination and remediation
Thirty hand-dug wells were identified and evaluated to study the groundwater flow dynamics and anionic species distribution in the study area. Topography and water table levels method with the aid of Surfer were adopted in the delineation of six recharge and discharge zones correspondingly...Read more

Experimental studies of the course of CO2/CH4 exchange sorption on hard coal subjected to confining pressure.

(Corresponding) Skoczylas N.
Topic: 
Gas emissions control and utilization
Studies were carried out on exchange sorption of CO2/CH4 on four samples of hard coal differing in the degree of coalification. The samples were subjected to various confining pressures in the range from 1.5 MPa to 30 MPa. The author's conception of the measuring apparatus made it possible to...Read more

Effect of confining pressure on sorption parameters and structure of coal in terms of analyzing the possibility of underground CO2 storage with CH4 recovery.

(Corresponding) Pajdak A.
Topic: 
Gas emissions control and utilization
An original apparatus was constructed, allowing observation of sorption processes occurring in hard coal briquettes. The investigations were carried out on four hard coals from Poland and France differing in the degree of coalification. The coal briquettes were subjected to confining pressure with...Read more

Laboratory studies of coal permeability under conditions corresponding to in situ, in terms of assessing the possibility of underground CO2 storage with CH4 recovery

(Corresponding) Kudasik M.
Topic: 
Gas emissions control and utilization
Investigations of processes accompanying the exchange sorption of CO2/CH4 under confining pressure in the range of 1.5 MPa to 30 MPa have been carried out.
