    Author : Klara Losman Nädele; [2021]
    Keywords : ekologisk; restaurering; Storsjön; Östersund; social; hållbarhet; platsspecificitet;

    Abstract : Det här arbetet är sprunget ur den allt vanligare företeelsen att gamla industriområden förändras till generiska platser till följd av förtätning. Områden som dessa besitter ofta platsspecifika egenskaper som kan ligga till grund för unika livsmiljöer. Mellan järnvägen och Storsjön i Östersund sträcker sig Storsjöstråket. READ MORE

  4. 3. Aquaculture in Lake Storsjön: an ecosystem services based investigation

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : Pietro Marcianò; [2015]
    Keywords : ecosystem services; aquaculture; CICES; Sweden; trade-offs;

    Abstract : The purpose of this thesis is to investigate if the application of the ecosystem services concept can provide decision makers and stakeholders with additional relevant information for decisions regarding establishing of aquaculture on a local level, using the Lake Storsjön as a case study. In order to provide this knowledge, three different tasks are carried out within this thesis: the identification of the main ecosystem services provided by Lake Storsjön, the understanding of ecosystem services that will be affected by the expansion of aquaculture and the identification of the services that will be used for a possible expansion of the aquaculture sector.

  5. 4. Geochemical and palaeomagnetic characteristics of a Swedish Holocene sediment sequence from Lake Storsjön, Jämtland

    University essay from Lunds universitet/Geologiska institutionen

    Author : Joakim Robygd; [2015]
    Keywords : Jämtland; geochemistry; palaeomagnetism; PSV; sedimentation rate; Holocene development; geochronology; climate change; Earth and Environmental Sciences;

    Abstract : As a part of a French-Swedish collaboration project to reconstruct middle to northern European climate variations during the Holocene, a sediment sequence from Lake Storsjön, Jämtland was retrieved and analysed for geochemical and palaeomagnetic properties. The subsampled sequence, composed of one freeze core and three Niederreiter piston cores, revealed information of both climatic, environmental and anthropogenic changes over the past 10,800 years.

  6. 5. Acid neutralization using steel slags : Adsorption of fluorides in solutions using AOD slags

    University essay from KTH/Materialvetenskap

    Author : Jesper Larsson; [2015]
    Keywords : acid neutralization; AOD slag; fluoride adsorption; syraneutralisering; AOD slagg; fluoradsorption;

    Abstract : Surface treatment processes of stainless steel, such as pickling, produces acidic waste water consisting of Na⁺, Cl⁻, F⁻, NO⁻3, SO42-, PO43-, Fe3+, Cr6+ and Ni2+. At Sandvik ABs steel works in Sandviken, this waste water is treated and neutralized using slaked lime before being released into the lake Storsjön. READ MORE
