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

Thermodynamic model for a reversible desalination cycle using polyelectrolyte hydrogels

(Corresponding) Rud O., Košovan P.

Topic:

Desalination

We propose a novel desalination scheme which employs the hydrogels as a tool to draw salt ions from a brine with low salinity to a brine with high salinity. As a driving force we use the fact that the volume of polyelectrolyte gel does depend on the surrounding salinity. While the salinity...Read more

The thermodynamic model of improved desalination using hydrophobic polyelectrolyte gels

(Corresponding) Rud O., Prokacheva V., Uhlik F.

Topic:

Desalination

We study a weak polyelectrolyte hydrogel and its application as a desalination agent. We model the desalination process as a four-step reversible thermodynamic cycle transferring ions from a low salinity solution to a high salinity one. As a driving force for ions movement, we use the fact that...Read more

Energy and environmental aspects of distributed generation and electric-vehicle integration from a LCA perspective. A case study in Mendoza, Argentina

(Corresponding) Arena A.

Topic:

Life cycle analysis (lca)

The energy sector is moving from a rigid, concentrated system towards a flexible, decentralized one enabling the exchange of energy between many actors. Distributed renewable energy generation is a key player in this new system, offering many advantages, but their intermittent character and the...Read more

Cloning and sequencing of the gene encoding the enzyme for the reductive cleavage of diaryl ether bonds of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in Geobacillus thermodenitrificans UZO 3

(Corresponding) Suzuki Y., Nakamura M., Otsuka Y., Sato-Izawa K., Hishiyama S., Kameyama K., Kameyama T., Takahashi A., Katayama Y.

Topic:

Environmental biotechnology and bioenergy

We have previously reported that a cell-free extract prepared from Geobacillus thermodenitrificans UZO 3 reductively cleaves diaryl ether bonds of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), a dioxin with the highest toxicity, in a sequential fashion producing 3’,4’,4,5-tetrachloro-2-...Read more

"Reliable in-Situ Sensing of Water Quality Parameters Using Low Cost Autonomous Analysers - Opportunities and Challenges"

Donohoe A., Hazel C., McCluskey P., McCaul M., (Corresponding) Diamond D.

Topic:

Process understanding through innovative sensors and remote sensing

The delivery of platforms that can provide access to good quality analytical information on the chemical/biological status of water at an acceptable cost remains a formidable challenge, despite considerable efforts from the research community over many years. The relatively high cost of autonomous...Read more

Groundwater quality and hydrogeochemical characterization of Khetri copper mining region, India

(Corresponding) Punia A., Siddaiah N., (Corresponding) Bharti R.

Topic:

Soil and groundwater contamination and remediation

The impact of copper mine on groundwater quality in the semi-arid region is evaluated, and also characterized for hydrogeochemical processes. Groundwater samples (post monsoon and pre monsoon) from Khetri copper mine region of Rajasthan, India were studied. In majority of groundwater samples, the...Read more

Analysis of degradation of the micropollutant amoxicillin by photolysis and evaluation of the degradation products

(Corresponding) Hoehne L., Vettorello G., Ethur E., Kuhn D., Freitas E., Steffens C.

Topic:

Emerging pollutants

Emerging micro pollutants are substances that have recently been identified in environmental matrices, of which information on environmental permanence and toxicity is still scarce. Because of their chemical structure, antibiotics are more stable and require more complex processes for degradation...Read more
