  2. 21. Modeling pooling and perishable items in inventory systems

    Author : Patrik Tydesjö; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two level; perishable items; Inventory control; newsboy model; emergency supply; stochastic; lateral transshipments; upstream customer demand.;

    Abstract : This thesis is built on three papers considering different problems in inventory control. The first paper considers a two-location newsboy model with the possibility of making lateral transshipments when needed. Usually, when considering newsboy models it is assumed that all demand in a period occurs at once. READ MORE

  4. 22. Diffusion studies in gels using holographic laser interferometry

    Author : Charlotte Mattisson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

  5. 23. Compaction, Flow and Dispersion in a Chromatographic Column

    Author : Karin Östergren; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; compression; chromatography; particulate bed; hydrodynamic dispersion; theoretical model; flow field; Livsmedelsteknik;

    Abstract : An experimental and theoretical study of compaction, flow and hydrodynamic dispersion in a chromatographic column containing non-rigid particles is presented. Experiments were performed using chromatographic columns packed with either a dextran-based chromatographic gel or glass beads. READ MORE

  6. 24. Climate and dengue fever : early warning based on temperature and rainfall

    Author : Yien Ling Hii; Nawi Ng; Joacim Rocklöv; Rainer Sauerborn; Sven Britton; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dengue fever; temperature; rainfall; forecasting model; early warning; epidemic; dengue risk index; folkhälsa; Public health;

    Abstract : Background: Dengue is a viral infectious disease that is transmitted by mosquitoes. The disease causes a significant health burden in tropical countries, and has been a public health burden in Singapore for several decades. Severe complications such as hemorrhage can develop and lead to fatal outcomes. READ MORE

    Abstract : En sjukdom kan många gånger härledas till en kaskadereaktion mellan proteiner, co-faktorer och substrat. Denna kaskadreaktion blir många gånger målet för att behandla sjukdomen med läkemedel. För att designa nya läkemedelsmoleyler används vanligen datorbaserade verktyg. READ MORE
