  1. 1. Sustainable Development: Implementation in Urban Water Systems

    Author : Ali Bagheri; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; Naturvetenskap; Natural science; Water resources systems; Viability loops; Urban water system; System dynamics; Sustainable development; Strategy; Social learning; Process; Principles; Indicators; Planning; Monitoring; kontroll av utsläpp;

    Abstract : As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. READ MORE

  2. 2. Microbial risk assessment and its implications for risk management in urban water systems

    Author : Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE

  3. 3. Insufficient water supply in an urban area - case study : Tegucigalpa, Honduras

    Author : Zairis Aida Coello Midence Balthasar; Jan-Erik Gustafsson; Berit Balfors; Mats Lannerstad; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water supply; Honduras; SANAA; Tegucigalpa; water utility;

    Abstract : Tegucigalpa, the capital of Honduras, has experienced an unsatisfied water demand during the last three decades. The state owned water utility in charge of the water supply of the country, SANAA, has faced this deficit by providing an intermittent water supply. READ MORE

  4. 4. Urban water management : Modelling, simulation and control of the activated sludge process

    Author : Mats Ekman; Bengt Carlsson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Abstract : During the last few decades, wastewater treatment processes in urban water management have become more and more efficient and complex. Several factors such as urbanization, stricter legislations on effluent quality, economics, increased knowledge of the involved biological, chemical and physical processes as well as technical achievements have been important incentives for the development of more efficient procedures for wastewater treatment plants.

  5. 5. The Auroral Large Imaging System : design, operation and scientific results

    Author : Urban Brändström; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Aurora; Artificial airglow; HF-pump enhanced airglow; Multistation measurements; Polar Stratospheric clouds; Radio-Induced optical emissions; Spectroscopic imaging observations; Tomography; Rymd- och plasmafysik; Space physics; Rymdfysik; rymdfysik; Space Physics;

    Abstract : The Auroral Large Imaging System (ALIS) was proposed in 1989 by Åke Steen as a joint Scandinavian ground-based nework of automated auroral imaging stations. The primary scientic objective was in the field of auroral physics, but it was soon realised that ALIS could be used in other fields, for example, studies of Polar Stratospheric Clouds (PSC), meteors, as well as other atmospheric phenomena.
