  1. 1. Water quality and organic matter linkages in waters draining arable fields

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Adam Eriksson; [2021]
    Nyckelord :Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Stacy Sutliff-Johansson; [2015]
    Nyckelord :MS2; time-dependent removal; adsorption; organic matter effects; virus contamination; Uppsala; MS2; adsorption; organiskt material effekt; virus kontaminering; dricksvatten; Uppsala;

    Sammanfattning : 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. LÄS MER

  4. 3. Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia

    Kandidat-uppsats, Göteborgs universitet/HDK - Högskolan för design och konsthantverk

    Författare :Cathrine Hagman; [2014-03-13]
    Nyckelord :Body; death; decomposition; human; materials; movie;

    Sammanfattning : In this project the author made an attempt to, in a short film, visualize an experience of the organic materials that our bodies consist of and what becomes of it when we die. The intention was to dissect this matter, break it down to see it in a simpler form and to explore our relationship to it, being part of a constant exchange between organic materials and having so much power over the environment and other living animals.

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

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

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

    Sammanfattning : 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. LÄS MER

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

    L3-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Björn Erhagen; [2007]
    Nyckelord :kvicksilver; metylering; svavel; organisk materia; sulfater; riskbedömning; sediment;

    Sammanfattning : 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. LÄS MER
