  1. 1. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Lindgren; [2021-03-10]
    Keywords : acid sulphate soils; metal distribution; surface water; climate; physicochemistry;

    Abstract : Acid sulphate soils have been referred to as being among the most harmful soils in the worlddue to their ability to severely decrease the pH of the water, consequently enabling an increasedmetal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presenceof acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and thesoils are today threatening many of the national environmental goals of Sweden. READ MORE

  2. 2. Development of a novel quantitative PCR analysis method for HIV-1

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Teoretisk kemi

    Author : Anna-Malin Hallberg; [2021]
    Keywords : HIV; PCR; primers; probes; virus; detection; blood plasma; pathogen; biological pharmaceutical; protein-based pharmaceutical; genotype; subtype; RT qPCR; extraction; TaqMa; RNA virus; cross-dimer; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering; Chemistry;

    Abstract : Biological pharmaceuticals are the answer to many severe diseases of today’s society. Some of these are protein-based drugs and can be produced from human blood plasma. In order to guarantee the safety of patients, absence of any pathogens needs to be ensured. READ MORE

  3. 3. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Andreas Vernby; [2021]
    Keywords : Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

    Abstract : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. READ MORE

  4. 4. Effects of Elaphostrongylus spp. infection on haematology and blood chemistry – in moose (Alces alces), reindeer (Rangifer tarandus), goat (Capra aegagrus hircus) and sheep (Ovis aries)

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Elin Engerström; [2021]
    Keywords : E. alces; E. rangiferi; elaphostrongylosis; muscleworm; brainworm; small ruminant; eosinophilia; biochemistry; serum chemistry;

    Abstract : The aim with this study was to investigate the effects Elaphostrongylus alces and Elaphostrongylus rangiferi have on haematology and blood chemistry in experimentally infected animals. The nematodes of genus Elaphostrongylus spp. can cause neurologic disease, myositis, verminous pneumonia and increased mortality. READ MORE

  5. 5. The nutrient-color paradigm : A test based on a comperative analysis of lakes in four ecoregions in Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Viktoria Nordström; [2021]
    Keywords : ;

    Abstract : The nutrient-color paradigm explains lake productivity as a function of the concentrations of nutrients and colored dissolved organic matter (CDOM) in the water column.  Specifically, the paradigm predicts that primary production decreases with increasing concentrations of CDOM due to reduced light penetration, and increases with nitrogen or phosphorus concentration because these are typically the growth limiting elements for phytoplankton.
