  1. 1. Energy in the Transportation System - A comparison of charging infrastructure scenarios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Judith Lai Jakobsson; [2023]
    Nyckelord :Charging infrastructure; road transport electrification; battery capacity need; electric vehicles; Technology and Engineering;

    Sammanfattning : A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. LÄS MER

  3. 2. Pre-study and Conceptual Design of a Hydrogen Fuel Cell Driven Wheel Loader

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Jana Caspari; Pijus Bernatavicius; [2022]
    Nyckelord :PEM fuel cell; hydrogen; drive cycle analysis; large-size wheel loader; architecture generation; packaging;

    Sammanfattning : Volvo Construction Equipment is one of the leading construction machinery manufacturers in the world. To stay amongst the leaders, research and development projects for new technologies are crucial. The most important path of development today is the reduction of emissions produced by these heavy duty vehicles. LÄS MER

  4. 3. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :Qianhui Liu; [2022]
    Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  5. 4. Simulation of periodic counter-current chromatography purification of monoclonal antibodies with column degradation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Friberg; [2022]
    Nyckelord :Counter-current chromatography; PCC; Monoclonal antibodies; Affinity chromatography; Process control; Chemical engineering; Process simulation; Chemistry;

    Sammanfattning : The purification process of monoclonal antibodies (mAbs) for therapeutic drugs is expensive, especially the chromatography step in which the mAbs are separated from other proteins and cells present in the feed. The antibodies are separated from the feed using affinity chromatography, where only the antibodies interact with active sites within the column, whereas the rest passes through the column without stopping.

  7. 5. Guns, Rebels & Pasture in the Great Acceleration : Decreasing land productivity and conflict intensity in South Sudan

    Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Akseli Laurila; [2021]
    Nyckelord :Pastoralism; land productivity; South Sudan; desertification; climate change; livelihoods.;

    Sammanfattning : The relationship between environmental change and violent conflict has increasingly received attention in recent years. Most of the research has focused on fast-onset environmental disasters, rather than slow-moving environmental processes, however. LÄS MER
