  1. 1. Probing the Precipitationshed : A quantification of the biophysical dimensions of terrestrial moisture recycling

    Författare :Patrick W. Keys; Line Gordon; Steve Lyon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; moisture recycling; precipitation; evaporation; variability; ecosystem services; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Terrestrial moisture recycling is the phenomena whereby water evaporates from the land surface, travels through the atmosphere, and fall as precipitation downwind. The interaction of societies with this branch of the hydrological cycle, though critical to the productive functioning of ecosystems around the planet, remains poorly understood. LÄS MER

  3. 2. The Precipitationshed : Concepts, Methods, and Applications

    Författare :Patrick W. Keys; Line Gordon; Deliang Chen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water; atmosphere; precipitationshed; moisture recycling; variability; ecosystem services; social-ecological systems; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Human societies are reliant on the functioning of the hydrologic cycle. The atmospheric branch of this cycle, often referred to as moisture recycling in the context of land-to-land exchange, refers to water evaporating, traveling through the atmosphere, and falling out as precipitation.

  4. 3. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions

    Författare :Walker Camacho; KTH; []
    Nyckelord :recycling; hdpe; pp; blends; nylon 6.6; abs; water content; mae; gc-ms; mir; chemiluminiscence;

    Sammanfattning : Different methods for quality assessment of separated andcommingled plastics from household and electronic waste havebeen developed. Especial attention has been given tospectroscopic methods since they are non-destructive andrequire little or no sample preparation at all. LÄS MER

  5. 4. Hydrometallurgical recovery of rare earth elements from flourescent lamp waste fractions

    Författare :Cristian Tunsu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rare earth elements; recycling; fluorescent lamp waste; solvent extraction; waste treatment; Cyanex 572; leaching; Cyanex 923;

    Sammanfattning : Recovery and reuse of materials is important for a circular economy. In recent years the recovery of critical metals from end-of-life products has received increased attention. Various streams, e.g. LÄS MER

  7. 5. Automated Manufacture of Fertilizing Agglomerates from Burnt Wood Ash

    Författare :Thomas Svantesson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Filtering; Ash Recycling; Change Detection; System Identification; Real-Time Control; Robust Control; Process Design; Control System Design; Carbon In Fly Ash CIFA monitoring; PID-Control; Agglomeration Techniques; Moisture Control; Dehydration Techniques.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase.
