  1. 21. On the morphosyntax of main and subordinate clauses in Xokleng

    Kandidat-uppsats, Lunds universitet/Allmän språkvetenskap

    Författare :David Gert; [2019]
    Nyckelord :subordination; word order; Xokleng; nominalization; Languages and Literatures;

    Sammanfattning : This is a thesis on the Gê language of Xokleng and its means of subordination. This work is based on previous publication on the Xokleng language (Urban 1985, Gakran 2005, Gakran 2015). In this highly isolation language with almost no inflection, a large set of grammatical and lexical monosyllabic particles are used to express TAM(E). LÄS MER

  3. 22. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Elfving; [2019]
    Nyckelord :frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. LÄS MER

  4. 23. Critical thermal minimum of the embryonic development in the common frog (Rana temporaria)

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Pontus Eriksson; [2019]
    Nyckelord :development; Rana temporaria; Anura; critical thermal minimum; embryonic; temperature; degree-days; day; degrees; Oophila; common frog; Ranidae; amphibian; algae;

    Sammanfattning : The embryonic development of anurans is known to be temperature-dependent and well-studied. Oviposition of Rana temporaria (common frog) in the northern temperate climate zone occurs as soon as the ice melts on water bodies. This early oviposition can take place in waters below 5 °C.

  5. 24. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Xiaoying Zhang; [2019]
    Nyckelord :;

    Sammanfattning : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. LÄS MER

  7. 25. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Författare :Christopher Hampton; [2019]
    Nyckelord :;

    Sammanfattning : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. LÄS MER
