1. 1. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Gila van den Eijnde; [2023]
   Nyckelord :Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

   Sammanfattning : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. LÄS MER

3. 2. Fuktinducerade sprickors inverkan på hålkanthållfastheten och hålstyvheten hos dymlingar i gran och björk belastade vinkelrätt mot fiberriktningen

   Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Sarhatlic Benjamin; [2022]
   Nyckelord :;

   Sammanfattning : In our modern times, the aim in the construction industry is to lower the environmental impact. This can be done by using materials with a lower impact on the environment. One of these materials is wood. Due to research and increased understanding of wood, it is now possible to construct multiple-storey buildings using wood. LÄS MER

4. 3. Wood and moisture-induced strains in a large deformation setting in 3D

   Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Fredrik Ström; Anwar Obeido; [2022]
   Nyckelord :Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

   Sammanfattning : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. LÄS MER

5. 4. The influence of passive measures on the highly demanding room climate requirements of a museum building in terms of sustainability

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Jasmin Jost; [2021]
   Nyckelord :museum; museum climate; conservation requirements; climate risk assessment; indoor environment; thermal comfort; thermal mass; moisture buffering; hygroscopic materials; life cycle assessment LCA ; Technology and Engineering;

   Sammanfattning : In the exhibition space of a museum, a compromise between the requirements for the preservation of cultural goods and thermal comfort criteria for visitors has to be applied. Such a high level of control without allowing fluctuations in temperature and relative humidity poses a big challenge to the air conditioning systems to maintain these very specific hygrothermal conditions.

7. 5. Metoder för att utforma fackfyllnadens möte med stolpen i ett halvnaket skelettverk

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Johan Jönsson; [2019-04-01]
   Nyckelord :Timber framing; Half-timber work; Post and Beam; Skeleton construction; Frugal building crafts; Infill; Skelettverk; Stolpverk; Korsvirke; Korsverk; Skiftesverk; Frugal byggnation; Skelettkonstruktion; Skelettsystem; Balk-pelarsystem;

   Sammanfattning : This thesis investigates eight different industrially processed building products and how they can be used on a traditional half-timbred work and still leave the timbers exposed both internally and externally. The focus is on the joint between the infill and the post, where the highest risk of air leakage occurs. LÄS MER
