Assessment of the effects of mechanical bottom sludge removal from lakes Didžiulis and Lentvaris (Trakai district) based on macrozoobenthos indicators
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Two lakes in Trakai district – Didžiulis and Lentvaris were heavily polluted in the past by discharges of municipal wastewater without proper treatment. This anthropogenic impact resulted in large amounts of bottom sludge ... -
Effects of salinity on earthworm (Eisenia fetida)
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Road salts negatively affect environment ecosystems. Sodium chloride (NaCl) from runoff is responsible for the increased salinity of soil surface and ground waters. The aim of the study was to assess the effects of salinity ... -
Leachate dynamics of Jerubaičiai landfill
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Human activities are inevitably associated with the generation of waste. The more urbanized society is, the larger the volumes of waste generated, and more problems are associated with their management. The aim of this ... -
Modelling of aqueous foam flow for developing energy-efficient heat exchanger applications
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Two-phase aqueous foam flow was modelled for developing energy-efficient heat exchangers. Such heat exchangers can provide low consumption of energy resources due to enhanced heat transfer rates. In this study enhancement ... -
From transformation to transition as permanent process. Some aspects of environmental issues being important for a small country after transformation period
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Chances and risks always go along with any change. But the transformation of Lithuania from a former part of a socialist society to an independent liberal market oriented society was a major change not having been experienced ... -
Possibilities of coal fly ash utilization in the low temperature belite cement production
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)At present, belite cement synthesizing has become the hotspot in cement-concrete materials science. Many investigations have been realized in order to synthesize belite (β polymorph modification of C2S) from coal fly ash ... -
Catalysts supported on alumina-silica glass fiber for neutralization of waste gases
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Technological parameters of catalysts production based on glass fiber have been investigated. Catalysts were made by deposition of different active metal ions on the amorphous glass matrix. The experimental results suggest ... -
Environmental optimization of structures in terms of used materials
(8th International Conference “Environmental Engineering” (ICEE-2011), 2011)Building materials play important role in buildings construction as well as have massive contribution to impact of buildings on environment. Materials influence global climate by emitting greenhouse gasses, acidification ... -
