  1. 6. Mass flows of per- and polyfluoroalkyl substances (PFASs) in a Swedish wastewater network and treatment plant

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Linda Glimstedt; [2016]
    Keywords : per- and polyfluoroalkyl substances; PFAS; 6:2 FTSA; wastewater; wastewater network; wastewater treatment; WWTP; Uppsala; Kungsängsverket; per- och polyfluoroalkylerade substanser; PFAS; 6:2 FTSA; avloppsvatten; ledningsnät; avloppsnät; avloppsvattenrening; reningsverk; Uppsala; Kungsängsverket;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made substances that hold unique properties. They are not only oil- and water repellants but also very resistant to degradation. Due to these properties, the applications are endless and PFASs can be found in a wide range of industrial applications and commercial products. READ MORE

  3. 7. Heat Resistant Steel Alloys : Atlas Copco

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Malin From; Johanna Ejerhed; Artin Fattah; Markus Lindén; Alex Karlstens; [2015]
    Keywords : steel alloy heat resistant nitration;

    Abstract : Atlas Copco is interested in investigating the friction in the top-hammer drilling tool threads thatcauses the steel to heat up, leading to a phase transformation and a softer steel in the threads. Theaim of this project is to find a steel alloy or surface finishing that will retain its hardness atelevated temperatures better than the presently used threads material. READ MORE

  4. 8. Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Erhagen; [2007]
    Keywords : kvicksilver; metylering; svavel; organisk materia; sulfater; riskbedömning; sediment;

    Abstract : Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. READ MORE

  5. 9. Snow or rain? - A matter of wet-bulb temperature

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Arvid Olsen; [2003]
    Keywords : condensation scheme; HIRLAM; MESAN; rain formation; snow formation;

    Abstract : Accurate precipitation-type forecasts are essential in many areas of our modern society andtherefore there is a need to develop proper working methods for this purpose. Focus of thiswork has been to study important physical processes decisive in deciding both the temperatureof the precipitation particles, hence affecting their phase, and the surrounding air.
