  1. 1. Energy Efficient Eradication of Legionella in Hot Water Systems

    Author : Lobna Altorkmany; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Disease related to unsafe water, poor sanitation, and lack of hygiene is some of the most common causes of illness and death all around the world. Since the first detection of Legionella in Philadelphia 1976, Legionella is recognized to cause Legionellosis which is associated with two distinct forms: Legionnaires’ disease and Pontiac fever.

    Keywords : HUMANIORA; HUMANITIES; urban water; urban sanitation; urban history; development studies; African history; environmental history; large technical systems; socio-technical systems; institutional change; public service; History of technology; Teknikhistoria;

    Abstract : This licentiate thesis describes and analyses the modern history of the socio-technical systems for urban water supply and sanitation in East Africa with focus on Uganda and Kenya. The key objective of the thesis is to evaluate to what extent the historic processes frame and influence the water and sanitation services sectors in these countries today. READ MORE

  3. 3. Infrared Laser-Induced Grating Techniques for Diagnostics in Reactive Flows

    Author : Dina Hot; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser diagnostics; infrared; laser-induced grating spectroscopy; degenerate four-wave mixing; flames; temperature; concentration; Fysicumarkivet A:2020:Hot;

    Abstract : AbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). READ MORE

  4. 4. When water becomes a threat : Risk assessment and risk management plans for floods and drinking water in Swedish practice

    Author : Viveca Norén; Kevin Bishop; Beatrice Hedelin; Lars Nyberg; Sven Halldin; Kurt Petersen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flood; Drinking water supply; Risk management; Risk assessment; Flood risk management plan FRMP ; Integrated flood management IFM ; Tools and methods; Practice compared to theory; Sweden; Municipalities; Interview study; Document study; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Water is an essential but vulnerable resource. A shortage of good quality drinking water is a threat to human health and society as a whole. Abundance of water in the form of floods can also be a serious threat which can have consequences for the drinking water supply. To reduce these risks there is a need for systematic risk reduction.

  5. 5. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

    Author : Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.
