Changes of Photosynthetic Performance of Brassica napus Affecting Cadmium Phytoextraction Performance under Elevated Temperature, CO2 and Drought
(Corresponding) Dikšaitytė A., Žaltauskaitė J., Kniuipytė I., Januškaitienė I., Juknys R.
Topic:
Heavy metals in the environment
This study aimed to investigate the Cd-removal efficiency from the soil by rapes (Brassica napus L.) under changing climate conditions, i.e. elevated temperature and CO2 with or without additional drought stress. As photosynthesis is the most important primary metabolic process, determining plant...Read more
Studies on the CO2 adsorption mechanism of Na-X and Na-Ca-X coal fly ash zeolites
(Corresponding) Boycheva S., Lazarova H., Zgureva D., Popova M.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZ) of Na-X and Na-Ca-X types were synthesized using as raw materials fly ashes generated by the combustion of lignite from various deposits with low and medium limestone content. It has been found that CFAZs with higher calcium content superior those containing less...Read more
Studies on the CO2 adsorption onto coal fly ash zeolites at elevated pressures
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZs) of Na-X type were prepared by ultrasonic-assisted double stage fusion-hydrothermal synthesis from lignite coal fly ash at two different fusion temperatures 550 and 800 C. The detailed surface analyses were performed experimentally using N2 physisorption technique and...Read more
A comparative study of alkali activated slag cement concretes with carbonate and silicate activators.
Sanam I., (Corresponding) Mavroulidou M.
Topic:
Environmental management and policies
Alkali-activated cements are increasingly gaining interest as viable alternatives to Portland cement, because they are considerably reducing CO2 emissions compared to traditional Portland cements while maintaining or exceeding performance requirements commonly specified for construction...Read more
Dairy farms management and carbon storage in the soil fractions
(Corresponding) Ferreiro-Domínguez N., Rigueiro-Rodríguez A., Miranda M., Mosquera-Losada M.
Topic:
Climate change mitigation and adaptation
The dairy sector is one of the main economic activities in the Spanish region of Galicia, located in the northwest of the country. In dairy farms, the type of farm management has a clear effect on climate change mitigation by modifying crucial processes such as carbon storage in the soil. This...Read more
Towards a sustainable water resources management in post-lignite era: the case of Western Macedonia, Greece
(Corresponding) Farmaki P., Tranoulidis A., Sotiropoulou R., Tagaris E.
Topic:
Water policy, management and society
In 2018, Public Power Corporation (PPC) employed 15,000 employees in the energy sector, mainly in lignite production, providing electricity to 6,900,000 customers in Greece. The total confirmed lignite reserves amount to 5 billion tons mostly resourced (1.8 billion tons) in the Western Macedonia...Read more

Effect of Castanea sativa plantation age on soil bacterial communities
(Corresponding) Alvarez-Lopez V., Ferreiro-Dominguez N., Mosquera-Losada R.
Topic:
Agroforestry, forest and agricultural sustainability
Soil microbial communities are involved in key processes of forest ecosystems that include decomposition of organic matter, cycling of nutrients or formation of structure. The composition and diversity of these communities depend on a large number of factors such as humidity, pH, nutrient levels, C...Read more
‘Water Underground’: Real-time, continuous monitoring of the underground water’s quantity and quality
Mavroforakis M., (Corresponding) Georgiou H., Malisiovas V., Psychias C., Papadimitriou D., Sarioglou K.
Topic:
Process understanding through innovative sensors and remote sensing
Water resource management is one the most urgent aspects of environmental protection and sustainability policies world-wide. Accurate, real-time remote sensing of the status of underground reservoirs is required for proper regional planning, prevention of droughts, optimized farming etc. ‘Water...Read more

Effect of the forage maize-pasture rotation on the soil carbon storage in Galicia (NW Spain)
(Corresponding) Ferreiro-Domínguez N., Rigueiro-Rodríguez A., Mosquera-Losada M.
Topic:
Climate change mitigation and adaptation
Galicia is a region in NW Spain with high economic dependence on dairy cattle where livestock feeding is mainly based on the production of forage maize. In this region, one of the major challenges for the forage maize production systems is to maximize the economic return while minimizing...Read more
A comparative assessment of alkali-activated stabilisers including waste materials, for the treatment of swelling-shrinking soils
(Corresponding) Mavroulidou M., Gray C., Gunn M.
Topic:
Solid waste management
Swelling-shrinking soils (also known as expansive soils) experience very considerable volume changes upon changes in moisture content, thus causing major damages to lightweight structures, pavements, slopes and utilities. To counteract this problem chemical stabilisation of this type of soil with...Read more
