    Abstract : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. READ MORE

  2. 2. Real-time imaging of cerebrospinal fluid flow physiology at 7T

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Olle Haglund; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Background The cerebrospinal fluid (CSF) is involved in several diseases and patho- physiological states, such as Alzheimer’s disease and hydrocephalus. Previous studies CSF dynamics in the brain show that the flow of the CSF depends on cardiac pulsation, time of day and respiration. READ MORE

  3. 3. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE

  4. 4. Characterization of black corrosion in reinforced concrete structures: analyses of field samples from southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jenny Halling; [2019]
    Keywords : black rust; anaerobic corrosion; reinforced concrete; corrosion products; green rust; microbial corrosion; Earth and Environmental Sciences;

    Abstract : I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. READ MORE

  5. 5. Problem Identification for Product Development Opportunities of Wine Refrigerators

    Abstract : Both value and flavor of wines can improve with time if stored properly. The factors with the most profound effect on the wine are light, humidity, temperature, vibrations, and ventilation. Light consisting of shorter wavelengths, under 450 nm, are dangerous for wine and can destroy the structure in wine. READ MORE
