  1. 1. Berättelser utan ord : Kommunikation genom samisk materiell kultur

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Johanna Lundin; [2018]
    Nyckelord :Communication; Sápmi; identity; Sami; archaeological studies; jewellery; iron age;

    Sammanfattning : This essay aims to gain a deeper understanding for the beliefs and identity of the sami people in Sápmi, northern Scandinavia through observation of their material culture. More specifically the object of interest is different types of jewellery made from materials like horn, silver and tin dat- ed to iron age 500 BC to 1300 AD. LÄS MER

  2. 2. Political Ecology of Tin Mining A Discourse Analysis of the Human-Environment Relation in the Study of Illegal Tin Mining on Bangka Island

    Master-uppsats, Lunds universitet/Humanekologi

    Författare :Tiara Elgifienda; [2018]
    Nyckelord :Illegal mining; Tin; Bangka; Political Ecology; Social Sciences;

    Sammanfattning : Bangka Island has been known as the most important tin producer in the world. Tin has developed the economy of the local people and even Indonesia in general. Unfortunately, mining is not only operated by corporations, but also by local people without proper procedures, resulting in a ruined landscape and ecosystem. LÄS MER

  3. 3. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rasmus Lavén; [2018]
    Nyckelord :Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Sammanfattning : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. LÄS MER

  4. 4. EBL Patterned ITO Contacts for Single Nanowire Devices

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Markus Snellman; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Nanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements.

  5. 5. Measurement of particle yields induced by 200-MeV protons on multiple targets

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Rafael Antonio Lopez; [2018]
    Nyckelord :QFS; Quasi-free Scattering; 16O; 112Sn; 124Sn; FAIR; CsI Tl ; R3B; 6.3-MeV gamma; CALIFA; p; 2p ; Physics and Astronomy;

    Sammanfattning : One way to probe the structure of atomic nuclei far from stability is via quasi-free scattering (QFS) reactions. We conducted a (p,2p) QFS experiment on H2O, 112Sn, 124Sn and 208Pb targets in order to test the performance of CsI(Tl) detectors that are to be used in the upcoming R3B experiments at FAIR. LÄS MER
