Inexpensive and universal growth media for biomass production of microalgae
Green Chemistry and Sustainable Development
New challenges for industrial microbiology and biotechnology of algae are to increase the efficiency of microalgae growth rates and decrease the cultivation costs. Algae could be cultivated in fresh water as well as in salty sea water or wastewater. Microalgae biomass can be used as a sorbent to...
Water Quality Monitoring with Emphasis on Estimation of Point and Diffuse Pollution Sources
Water Quality
Population growth, urbanization and anthropogenic activities are becoming a serious problem for water resources in Turkey, which necessitates their monitoring and maintenance of water quality. In this study, water quality was implemented in the Porsuk Stream in Inner Anatolia, Turkey. Water samples...
Optimizing operation of a large-scale pumped storage hydropower system coordinated with wind farm by means of genetic algorithms
Protection and restoration of the environment
Due to the intermittent and fluctuating nature of wind and other renewable energy sources, their integration into electricity systems requires large-scale and flexible storage systems to ensure uninterrupted power supply and to reduce the percentage of produced energy that is discarded or curtailed...
Investigation of Solid Waste Characteristics in Field-Scale Landfill Test Cells
Solid Waste Management
This paper presents the results of an experimental study carried out in field-scale test cells in order to determine the effect of aeration and leachate recirculation on waste decomposition rate, solid waste characteristics, landfill gas composition and settlement in the landfill body. Four landfill...
Evaluation of antimicrobial, antioxidant and cytotoxic activities and characterization of bioactive substances from freshwater blue-green algae
Multidisciplinary research in environmental science
Organic solvent extracts of three cyanobacterial species (Anabaena oryzae, Oscillatoria sp. and Stigonema ocellatum) were tested for antimicrobial activity against human pathogenic fungal and bacterial strains as well as for antioxidant and cytotoxic activity against human breast adenocarcinoma (MCF...
Using an online platform for the improvement of industrial symbiosis and circular economy (in Western Macedonia, Greece)
Green Chemistry and Sustainable Development
The part of industrial ecology known as industrial symbiosis engages traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water and by-products (Dounavis et al. 2015, Dounavis et al. 2016, Ravindran and Jaiswal 2016...
Impact of urbanization on climate change and geographical analysis of physical land use land cover variation using RS-GIS.
Hydrology and water resources
This study focuses on the impact of climate change on rainfall-runoff pattern, and to assess the surface runoff and groundwater recharge potential from the intensified rainfall for the effective management of surface and groundwater resources in Tirunelveli city. The rainfall contribution is...
Modelling the removal of Lead from synthetic contaminated water by activated carbon from biomass of Diplocyclos Palmatus by RSM
Multidisciplinary research in environmental science
Diplocyclos Palmatus biomass activated carbon (DPAC) was used in this work to remove lead (II) ion from the synthetic wastewater. The DPAC was characterized for structural, surface morphology by SEM, functional group was analyzed by FT-IR and XRD analysis. Removal of Pb2+ was studied by batch method...
Performance Evaluation of Fly Ash-based Geopolymer Concrete Incorporating Nano Slag
Green Chemistry and Sustainable Development
This study investigates the effectiveness of fly ash-based geopolymer concrete was conducted to be used as an alternative material to replace the normal concrete. The concrete mixture was prepared by mixing fly ash, fine aggregate, nano-slag, and SP in Na2SiO3/NaOH solution. The mixture was divided...
Composition and production rate of cytostatic pharmaceutical waste from a Greek Cancer Treatment Hospital
Hazardous Substances and Risk Analysis
The objective of this work was to determine the composition and production rate of cytostatic pharmaceutical waste produced by Theagenion Cancer Treatment Hospital (TCTH) in Thessaloniki, Greece. This information is necessary for the design and costing of management systems for cytostatic...
