  1. 1. Humle i vått och torrt : En metodstudie av stabila isotoper i recent och arkeologisk humle för att förstå ursprung och användning under svensk förhistoria och historisk tid

    Master-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kultur

    Författare :Kristin Alice Elisabeth Sjökvist; [2023]
    Nyckelord :humle; arkeologi; stabila isotoper; odling; medicinalväxter; öl; ölbryggning;

    Sammanfattning : In this thesis, material of recent hop from different locations in Sweden have been analyzed with EA-IRMS for carbon-, nitrogen- and sulfur isotopes. The aim has been to find a method to distinguish between cultivated and wild hops, and whether it is a useful method for provenancing of hop. LÄS MER

  3. 2. Comparing Quantum and Semi-Classical Approaches to Non-Collinear Magnetism in an Electron-Spin Dimer

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Sherwan Jamo Abdi; [2023]
    Nyckelord :Skyrmion Electron Spin Dzyaloshinskii-Moriya Interaction DMI Ehrenfest Semiclassical; Physics and Astronomy;

    Sammanfattning : In this bachelor thesis, an explorative theoretical analysis is presented on a model system characterized by various and competing magnetic interactions. The system comprises two localized magnetic moments (spins), and a single itinerant electron that hops between two orbitals located at the spins’ positions. LÄS MER

  4. 3. Analysis of polyfunctional thiols in beer : Developing a novel method of extraction and analysis using GC-FID

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

    Författare :Arvid Lindmark; [2022]
    Nyckelord :Beer; Hops; Thiols; 3MHA; 4MMP; Food Technology; Agriculture and Food Sciences;

    Sammanfattning : In this project, attempts were made to identify and quantify two polyfunctional thiols – 4-mercapto-4-methyl-pentanone and 3-mercaptohexyl acetate – and three monoterpene alcohols – linalool, geraniol, and β-citronellol – in beer samples. In order to avoid the use of hazardous compounds such as dichloromethane and hydroxymercuriobenzoate, common in traditional methods, two novel techniques were tested: a pure liquid-liquid extraction of the beer samples with cyclohexane, and a liquid-liquid extraction with cyclohexane followed by solid phase extraction on silver ion columns.

  5. 4. An Analysis on Bluetooth Mesh Networks and its Limits to Practical Use

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Minn Cho; Philipe Granhäll; [2021]
    Nyckelord :IoT; mesh networks; Bluetooth; Raspberry Pi 4; IoT; mesh nätverk; Bluetooth; Raspberry Pi 4;

    Sammanfattning : A mesh network is a technology that is being repopularized and becoming commonly used by the general public. As this increase in use is observed, technologies such as Bluetooth are being adapted to create mesh variants. In this thesis, a Bluetooth mesh network is created and tested using raspberry pi 4’s and the Bluetooth interface, btferret. LÄS MER

  7. 5. Post-Activation Performance Enhancement in Sledge Ankle Hops after a 6-seconds maximal Isometric Plantar Flexion

    Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

    Författare :Gabriel Solé; [2021]
    Nyckelord :sports; sprint; jumping; performance;

    Sammanfattning : Aim The aim of this study was to investigate the effects of a 6-second maximal voluntary isometric contraction (MVIC) of the plantar-flexors on subsequent ankle hops performed only by plantar flexing at the ankle. Methods 10 physically active university students were recruited to volunteer in this study. LÄS MER
