1. 1. BORTTAGNING AV TRYCKKÄNSLIG TEJP PÅ PAPPER En studie över användningen av hydrogeler

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Amanda Nyagake Mwita; [2023-11-07]
   Nyckelord :Pressure-sensitive tape; agar-gel; hydrogel; nanogel; paper conservation;

   Sammanfattning : 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.

3. 2. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Miri Katayon; [2022-07-05]
   Nyckelord :agar gel; metal conservation; nanomaterials; silver coating; sustainable conservation; varnish removal;

   Sammanfattning : The conservation of silver objects mainly constitutes addressing the issues of tarnish removal and of preventing tarnish. For decades lacquer has been used to coat silver objects in order to protect them from tarnishing. LÄS MER

4. 3. REMOVAL OF PRESSURE-SENSITIVE LABELS FOR LIBRARY APPLICATION A Study of the Use of Agar as a Solvent Gel

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Alexandra Tengelin; [2017-06-27]
   Nyckelord :self-adhesive labels; pressure-sensitive adhesive; agar gel; agarose; ATR-FTIR; paper conservation;

   Sammanfattning : The purpose of this study was to investigate pressure-sensitive labels for library application, techniques, and considerations for their removal from paper substrates. The aim was to use information from the literature to design a method for the removal of pressure-sensitive labels from paper covered half bindings using agar, commonly known as agar-agar, as a solvent gel.

5. 4. Development of a tissue-like protoporphyrin IX fluorescence phantom and performance of characterisation experiments

   Kandidat-uppsats, Biomedicinsk instrumentteknik; Tekniska högskolan

   Författare :Benjamin Kistler; [2013]
   Nyckelord :;

   Sammanfattning : Background and Objective: Fluorescence spectroscopy is a potential tool for brain tumour resection surgery. The main advantages of fluorescence spectroscopy are the objective fluorescence detection, possibility to quantify the signals and high sensitivity for instance to distinguish between healthy and neoplastic tissue.

7. 5. Reagerar grisar immunologiskt mot foderproteiner?

   L3-uppsats, SLU/Dept. of Clinical Sciences

   Författare :Lisa Haggård; [2008]
   Nyckelord :antikroppar; SDS-PAGE; soja; grisar;

   Sammanfattning : The aim of this study was to detect antibodies in swine serum against proteins in soy beans, wheat, oat and barley. Two methods were used: agar gel immunodiffusion test (AGID), and SDS-PAGE followed by immunoblotting. LÄS MER
