1. Tillväxt av öring (Salmo trutta) i bastuån : Täthets- och temperaturberoende?
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Performance of stream living juvenile brown trout (Salmo trutta) may be affected by both intra- and intercohort competition. In this study I examined if growth and density of cohorts of young-of the-year (0+) trout are dependent on temperature and density of older (>0+) trout and 0+ trout. LÄS MER
2. Techno-Economic Analysis of Dye Separation in Textile Recycling
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER
3. BORTTAGNING AV TRYCKKÄNSLIG TEJP PÅ PAPPER En studie över användningen av hydrogeler
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : The purpose of this thesis is to examine hydrogels practical efficiency in the removal of pressure-sensitive tapes on paper. The organic agar gel and synthetically produced Nanorestore Gel® PG5 Peggy Gel and Nanorestore Gel® High Water Retention are used in an experimental process upon removing three common pressure-sensitive tapes (PTSs) on paper.

4. Bläckborttagning från ben med hjälp av geler En kvantitativ studie för bläckborttagning på björnbäcken och björnkranium från Naturhistoriska riksmuseet
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : This bachelor's thesis has investigated four different hydrogels loaded in different solvents efficiency to remove unknown ink from four pelvic bones and one skull from five bear individuals that belongs to The Swedish Museum of Natural History. The experimental part of the thesis consists of an FTIR analysis together with microscopy and macroscopy analysis of the ink on the bear skeletons, as well as some tests of different gel-solvent combinations on a moose skull.

5. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. LÄS MER
