  1. 41. Recovery of Phosphorus from Incineration of Sewage Sludge

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Aditi Bhasin; [2017]
    Keywords : ;

    Abstract : The primary source of phosphorus, phosphate rock, is a non-renewable resource which is expected to get exhausted in the next 50 – 100 years.

  3. 42. Uppföjlning av SCA:s nya drivningsmetod "Skonsam Effektiv Drivning"

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

    Author : Karolina Ottosson; [2017]
    Keywords : Markfuktighetskarta; GPS-loggning; Körskador; Drivning; Planering;

    Abstract : Körskadeproblematiken inom skogsbruket har under flera år varit en prioriterad fråga. När körskador uppstår på skogsmarken på grund av drivning kan det ha oönskade effekter som t.ex. kvicksilverutlakning, tillväxtförluster och försämrade livsmiljöer för vattenlevande organismer.

Planetary systems detected with the radial velocity method might then contain undetected Earth-like planets. READ MORE

  6. 45. Catchment influences on mercury methylation in a peatland chronosequence

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Robin Hagblom; [2017]
    Keywords : methyl mercury; GIS; northern peatland; mire; watershed; elevation;

    Abstract : Since the beginning of industrialization, emissions of mercury (Hg) from human activities in excess of natural levels have increased depo-sition rates to ecosystems, storage in soils and loading to aquatic envi-ronments. Toxicity to animals, subject to this accumulation, as well as to humans consuming them, are the major concerns driving research on this subject. READ MORE
