  1. 16. The ultraviolet spectral slope of high-redshift galaxies

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Ludvig Sjöbom; [2016]
    Keywords : galaxies: high-redshift; observational astronomy; ultraviolet: galaxies; galaxies: evolution;

    Abstract : The slope of the ultraviolet continuum emissions from a galaxy between 1250 and 2600 Å provides insights about several facets of the galaxy. Mainly, it is well-correlated with the amount of dust. This work presents a search for objects whose UV-continuum slopes are excessively steep, as well as suggestions for follow-up. READ MORE

  3. 17. Markberedning i brant och stenig terräng : en jämförande studie mellan markberedning med harv, grävmaskin och spadförsedd skördare

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Malin Johansson; [2016]
    Keywords : planteringspunkter; ytstruktur; lutning; överlevnad; tillväxt; Heureka; nuvärde;

    Abstract : Markberedningsresultat för tvåradig harv, konventionell grävmaskin och skördare med kranspetsmonterat spadliknande markberedningsaggregat (spadförsedd skördare) jämfördes i ett fältförsök i Medelpad omfattande olika terrängsvårigheter i lutning och ytstruktur (lika Grundförhållanden men olika nivåer på Ytstruktur och Lutning, dvs. olika GYL-klasser).

  4. 18. Low-Frequency Noise in TFETs

    University essay from Lunds universitet/Fysiska institutionen

    Author : Markus Hellenbrand; [2015]
    Keywords : Tunnel Field-Effect Transistor; Steep-Slope Devices; III-V; InAs; GaSb; Broken Band Gap; Physics and Astronomy;

    Abstract : Nanowire tunnel field-effect transistors (TFETs) were investigated by carrying out noise measurements and low-temperature DC measurements. The TFET tunnelling junction was realised by a GaSb/InAs heterojunction resulting in a broken band gap. TFET noise currents were measured at frequencies between 10 Hz and 1 kHz. READ MORE

  5. 19. Model Calibration and Optimization of a Protein Purification Process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sadiq Al-Kaisy; [2015]
    Keywords : Model calibration; Protein purification; Ion-exchange chromatography; Optimization; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Abstract : Four different chromatography models were calibrated to describe the separation of a ternary protein mixture consisting of lysozyme, cytochrome C and ribonuclease A in an ion-exchange chromatography column. The models are based on the same column model, the kinetic dispersive model. READ MORE

  6. 20. Optimization of Physical Properties for Ditches–Case Study: Kankberg, Maurliden and Renström-Petiknäs.

    University essay from KTH/Mark- och vattenteknik

    Author : Ghebriel Kidane Ketema; [2014]
    Keywords : Drainage system; Ditches; Open channel flow; Steep slope; Mild slope; HEC-RAS; Super-critical flow; Critical flow; Sub-critical flow;

    Abstract : It is important for practical and legal reasons that water and sediments in disturbed areas around the mining operation should be controlled. The construction of a well-designed drainage system that controls erosion and thus restores the proper hydraulic function of the surface is one of the most important post-disturbance features which should be done as part of the mining activities.
