  1. 1. Levande begravd : kan klimatförändringar ge mjältbrandssporer nya förutsättningar?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Johanna Cavell; [2019]
    Keywords : mjältbrand; sporer; klimatförändringar;

    Abstract : Mjältbrand är en dödlig sjukdom som varit känd under en lång tid och som drabbar både djur och människor. En av anledningarna till att mjältbrand är fruktad är bakteriens förmåga att sporulera vid icke gynnsamma förhållanden och persistera i jorden under en lång tid. READ MORE

  2. 2. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  3. 3. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vilhelm Ekberg; [2019]
    Keywords : anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Abstract : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. READ MORE

  4. 4. Development of polymer based composite filaments for 3D printing

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Elin Åkerlund; [2019]
    Keywords : 3D-printing; fused deposition modeling FDM ; composite filaments; biocompatible materials; biodegradability; medical applications; scaffold materials; poly lactic acid PLA ; polycaprolactone PCL ; hydroxyapatite HA ; mechanical properties; thermal stability; chemical composition; morphological characterization; accelerated degradation study; polymer degradation behavior;

    Abstract : The relatively new and still growing field of 3D-printing has opened up the possibilities to manufacture patient-specific medical devices with high geometrical accuracy in a precise and quick manner. Additionally, biocompatible materials are a demand for all medical applications while biodegradability is of importance when developing scaffolds for tissue growth for instance. READ MORE

  5. 5. Mineral elements in clover- and grass forage in Sweden

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Kajsa Lätt; [2019]
    Keywords : soil; maps; forage; macro minerals; micro minerals;

    Abstract : Minerals are essential elements for all living organisms. Plants and animals need minerals to function and maintain a balanced physiological state. Minerals are also important in the ecological cycle. The minerals originate in the soil and makes the foundation of the plants nutritional value for the animals. READ MORE
