    Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

  3. 2. Effects of Organic Matter on Virus Removal with New and Used Sand in Tunåsen Infiltration Basin, Uppsala, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Keywords : MS2; time-dependent removal; adsorption; organic matter effects; virus contamination; Uppsala; MS2; adsorption; organiskt material effekt; virus kontaminering; dricksvatten; Uppsala;

    Abstract : Artificial infiltration has been increasing in popularity in Sweden as a way to combat over-abstraction of groundwater aquifers from growing municipalities. However, enteric virus contamination of drinking water sources is a concern as infiltrating surficial waters are easily contaminated from human activities. READ MORE

  4. 3. The infant incubator from a hygienic and HTO perspective : Using ATP luminescence to identify problem areas and suggesting solutions

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Stephanie Wikström; Simon Huisman; [2014]
    Keywords : incubator; ATP; hygienic; HTO; MTO; luminescence; hygiene; solutions; omnibed; warmer; neonate; neonatal; NICU; design; kuvös; neonatal; hygien; förtidigt; födda; barn; intensivvård; luminiscens; design;

    Abstract : Healthcare associated infections (HCAI) are a major problem in healthcare today. Preterm infants have problems keeping their body temperature within normal boundaries due to heat-loss. They therefore need special care that is administered with the help of incubators, which help minimise the heat loss via convection. READ MORE

  5. 4. Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Erhagen; [2007]
    Keywords : kvicksilver; metylering; svavel; organisk materia; sulfater; riskbedömning; sediment;

    Abstract : Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. READ MORE
