  1. 1. Household Waste Segregation: Lessons from Poland

    Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Alexander Stelmach; [2021-03-01]
    Nyckelord :;

    Sammanfattning : One of the problems facing the world in the twenty-first century is the management of municipal waste,a problem where the household plays a key role in the process through its interaction with themunicipal waste management system. How this interaction works is dependant not only on the designof the municipal waste management system, but also on the individual households. LÄS MER

  2. 2. Non-Linear strain paths in Sheet Metal Forming

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anton Eriksson; [2021]
    Nyckelord :Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Sammanfattning : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. LÄS MER

  3. 3. Integration of Hydrogen Production via Water Electrolysis at a CHP Plant : A feasibility study

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Ottosson; [2021]
    Nyckelord :Electrolyzer; Energy; CHP; Hydrogen; Feasibility; PEM; water electrolysis; Elektrolysör; Energi; CHP; Vätgas; PEM; vattenelektrolys;

    Sammanfattning : Hydrogen gas (H2), that is not produced from fossil oil or natural gas, is expected to become a cornerstone in the energy transition strategy in Europe. The recent years, technological and economic advances in the electrolyzer area, along with political and corporate support, have put H2 at the forefront of many countries’ climate change agenda.

  4. 4. Likviditetens betydelse för lönsamhet : En kvantitativ studie på svenska småföretag

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för ekonomistyrning och logistik (ELO)

    Författare :Malin Gummesson; Martina Slaveska; [2021]
    Nyckelord :liquidity; profitability; effect; relationship; small companies; trade-off; likviditet; lönsamhet; betydelse; samband; småföretag; avvägning;

    Sammanfattning : Liquidity and profitability are both vital aspects of a company's survival. Earlier studies suggest that there is a trade-off between liquidity and profitability. Too much liquidity can lower the profitability but the company still needs to maintain sufficient liquidity in order to be able to meet their short-term obligations. LÄS MER
