  1. 1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Nina Olivier; [2024-01-30]
    Nyckelord :Icons; tempera; emulsions; analysis methods; ToF-SIMS;

    Sammanfattning : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

    Sammanfattning : Mass spectroscopy imaging (MSI) has become a vital tool in modern research due to its ability to visualize the spatial distribution of molecules within tissue samples. The collaboration between researchers at AZ, the University of Gothenburg, and Chalmers University of Technology using the NanoSIMS instrument and MSI-SIMS technology has opened up new avenues of exploration in pharmaceutical development, particularly in examining drugs and metabolites at sub-cellular levels.

  4. 3. Space Utilization in Road Transportation: A Case Study of Truck Deliveries

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Marija Nikolova; Sirious Nterai; [2023-07-03]
    Nyckelord :Distribution; Emissions; Packaging; Truck deliveries; Space Utilization; Space Optimization;

    Sammanfattning : Aim: To understand why big logistics companies do not focus their resources on improving space utilization and decreasing the phenomenon of empty running. Moreover, this study aims to present the potential economic and environmental benefits of reduced excess air in packaging and its effect on truck deliveries. LÄS MER

  5. 4. Prognostisering av framtida materialbehov i ERP-system : En fallstudie på Wexiödisk AB

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Oscar Lönnblom; Viktor Östergren; [2023]
    Nyckelord :Forecasting; SAP; ERP; MRP; carrying cost of capital; lead time; Safety stock; Prognostisering; SAP; ERP; materialplanering; kostnad för bundet kapital; ledtid; säkerhetslager;

    Sammanfattning : Utvecklingen av teknologin i dagens industrier förändras snabbt och för att bibehålla verksamhetens konkurrenskraft är det viktigt att förstå kundernas behov. Prognostisering är förväntat framtida behov baserad på historisk data. LÄS MER

  7. 5. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER
