1. 16. Development of an analytical method for the screening of meaty flavors in commercial foodstuff by SPME-GC/O-MS

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

   Författare :Ioannis Protopappas; [2021]
   Nyckelord :Gass Chromatography; Mass spectrometry; Meaty flavors; Aromas; Solid pahse microextraction; Mallaird; Lipid degradation; Food technology; Agriculture and Food Sciences;

   Sammanfattning : The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. LÄS MER

3. 17. Investigating the role of water in the protein dynamic transition

   Master-uppsats, Stockholms universitet/Fysikum

   Författare :Maddalena Bin; [2020]
   Nyckelord :Protein; water; protein dynamic transition; x-ray;

   Sammanfattning : Proteins undergo a dynamic transition at approximately 220 K, also called protein ’glass’ transition, below which temperature proteins lose their conformational flexibility and become biologically inactive. The protein dynamic transition has been observed for several proteins utilizing different techniques, such as inelastic neutron scattering, infrared spectroscopy and X-ray crystallography. LÄS MER

4. 18. Addisonkris hos hund : monitorering och omvårdnad av intensivvårdspatienten

   Kandidat-uppsats, SLU/Dept. of Clinical Sciences

   Författare :Jennifer Johansson; Michelle Larsson; [2020]
   Nyckelord :addisonkris; hund; hypoadrenokorticism; intensivvårdsavdelning; djursjukskötare; monitorering; djuromvårdnad;

   Sammanfattning : Addisonkris hos hund är en livshotande komplikation av den endokrina sjukdomen hypoadrenokorticism och kan leda till att hunden hamnar i en hypovolemisk och kardiovaskulär chock. En patient i Addisonkris är i behov av omfattande omvårdnad och noga monitorering. LÄS MER

5. 19. Effekt av fasändringsmaterial på hydratiseringprocessen hos Portlandcement: En experimentell studie

   Kandidat-uppsats, KTH/Byggteknik och design

   Författare :Lubna Al-Khaffaf; Hala Khalil; [2020]
   Nyckelord :Phase change material PCM ; established environmental requirements; hydration properties; heat flow; cement hydration; set time; energy consumption; slump flow; density; compressive strength.; Fasändringsmaterial PCM ; etablerade miljökraven; hydratiseringsegenskaperna; värmeflöde; cementhydratisering; inställningstid; energiförbrukning; slumflöde; densitet; tryckhållfasthet;

   Sammanfattning : The Phase change materials (PCM) have the ability to absorb and release heat as the temperature changes from high to low temperature and vice versa. The use of phase change materials has increased in the construction sector due to the established environmental requirements and the various application benefits, especially in the thermal comfort of building applications and construction of sustainable infrastructure around the world (Berardi and Gallardo, 2019).

7. 20. Investigating potential proton conductors: Doping BaTiO3 and SrTiO3 with Fe and Al

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

   Författare :Julia Löfstrand; [2020]
   Nyckelord :Proton conductor; perovskite; solid state synthesis;

   Sammanfattning : There are many interesting applications of proton conducting oxides, such as electrolytes in fuel cells, hydrogen sensors and catalytic membranes for hydrogenation or dehydrogenation of organic compounds. Previous work explored doping BaTiO3 with the Rare Earth Element (REE) Sc to introduce oxygen vacancies in the structure, making it a Proton Conductor (PC). LÄS MER
