    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; nationalekonomi;

    Abstract : Price Level Determination When Tax Payments Are Required in Money. We formalize the idea that the price level can be determined by a requirement that taxes be paid in money. READ MORE

  4. 2. Quantum Dot Solar Cells: Towards Environmentally Friendly Materials

    Author : Viktor A. Öberg; Erik Johansson; Muhammet S. Toprak; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum dots; Nano-crystals; Energy conversion; Solar cells; Quantum dot solar cells; Low toxicity; Silver Sulfide; Silver Bismuth Sulfide; Lead Sulfide; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : To decrease the world’s energy dependence on fossil fuels, energy production and specifically electricity production needs to shift to more sustainable alternatives. One such alternative is solar cells as they directly convert energy emitted from the sun into electricity. READ MORE

  5. 3. Benefits of Digital Technical Information

    Author : Karin Ahlin; Erik A. M. Borglund; Lena-Maria Öberg; Tero Päivärinta; Pasi Tyrväinen; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; digital technical information; benefit; intangible benefit; interpretative research; manufacturing organization; digital teknikinformation; nytta; omätbara nyttor; tolkande forskning; tillverkande organisation;

    Abstract : In our daily work life, we use a wealth of information, including a category of information produced as a part of products and their life-cycle phases, named digital technical information (DTI). Manufacturing organizations focus more often on the product than on DTI, because DTI’s impact seems almost invisible, despite its crucial role to the product and its life-cycle phases, development, production, maintenance, and destruction.

  6. 4. In the Shadow of Settlement : Multiple Rebel Groups and Precarious Peace

    Author : Desirée Nilsson; Mats Hammarström; Magnus Öberg; Erik Melander; Virginia Page Fortna; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peace and conflict research; peace agreement; civil war; conflict resolution; rebel group; negotiated settlement; bargaining; conflict termination; durable peace; internal conflict; duration analysis; Freds- och konfliktforskning;

    Abstract : How can durable peace be achieved in the wake of a civil war settlement? Previous quantitative research on this topic has, so far, mainly focused on two parties – the government and the opposition – thereby failing to consider the complexity that may arise in conflicts where the rebel side involves several groups. This dissertation addresses this gap in the study of durable peace. READ MORE

  7. 5. Tight-binding calculations of electron scattering rates in semiconducting zigzag carbon nanotubes

    Author : Kannan Thiagarajan; Ulf Lindefelt; Hans-Erik Nilsson; Sven Öberg; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tight-binding; carbon nanotubes; electron-phonon scattering; backscattering; forward scattering; Semiconductor physics; Halvledarfysik;

    Abstract : The technological interest in a material depends very much on its electrical, magnetic, optical and/or mechanical properties. In carbon nanotubes the atoms form a cylindrical structure with a diameter of the order 1 nm, but the nanotubes can be up to several hundred micrometers in length. READ MORE
