1. 1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection

   Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Nina Olivier; [2024-01-30]
   Nyckelord :Icons; tempera; emulsions; analysis methods; ToF-SIMS;

   Sammanfattning : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

3. 2. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Björn Andermo; [2024-01-22]
   Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

   Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

4. 3. Betesrestaureringens effekter på växtartrikedom och biologisk mångfald : -restaurering av betesmark på Hallands Väderö

   Kandidat-uppsats, Karlstads universitet/Avdelningen för biologi; Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Rolfsdotter Söderberg Ylva; [2024]
   Nyckelord :pasture restoration; biodiversity; species richness; effective number of species; plants; plant species; number of species; clearing; pasture; betesrestaurering; biologisk mångfald; artrikedom; effektivt artantal; växter; växtarter; antal arter; artantal; hävd; betesmark; naturbetesmark;

   Sammanfattning : Abstract Pasture is a very species-rich but threatened nature type, and compared to 200 years ago, only five percent of natural pastures remain in Sweden. One way to try to save the biological diversity that pastures harbor is to restore overgrown land by clearing and reintroducing grazing animals. LÄS MER

   Sammanfattning : Big organisations and companies in game development and distribution have in recent years become involved in public-relations crises. In the past you could see that dissatisfied consumers have an impact on the image for organisations. LÄS MER

7. 5. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Walter Gezelius Gezelius; [2024]
   Nyckelord :Restoration; Environmental flows; riparian vegetation;

   Sammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER
