  2. 16. Mechanistic Toxicology : Molecular interactions and underlying mechanisms of dendritic cell activation in skin sensitization

    Author : Tim Lindberg; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skin Sensitization; Toxicology; Mechanisms; Dendritic Cells;

    Abstract : Allergic skin diseases caused by low molecular weight chemical compounds are a major health concern among the general population, especially in certain occupational groups. To limit exposure to such compounds, it is important that thorough risk assessments are performed before products reach the consumer market. READ MORE

    Author : Madeleine Ramstedt; Staffan Sjöberg; Per Persson; Lars Lövgren; Steven A. Banwart; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; manganite; γ-MnOOH; mineral surface; acid-base properties; adsorption; Cd II ; N- phosphonomethyl glycine; glyphosate; PMG; surface complex; dissolution; disproportionation; XPS; EXAFS; infrared spectroscopy; SEM; AFM; potentiometry; electrophoresis; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : The chemistry of mineral surfaces is of great importance in many different areas including natural processes occurring in oceans, rivers, lakes and soils. Manganese (hydr)oxides are one important group to these natural processes, and the thermodynamically most stable trivalent manganese (hydr)oxide, manganit (γ-MnOOH), is studied in this thesis.

  5. 18. Resource efficient control of Elymus repens

    Author : Björn Ringselle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Elymus repens is a perennial grass weed that causes great yield losses in a variety of crops in the southern and northern temperate zones. Primary control methods for E. repens are herbicides or intensive tillage, both of which have a number of negative side-effects, e.g. READ MORE

  6. 19. Solute transport in the integrated soil-groundwater system

    Author : Eva Simic; KTH; []
    Keywords : solute transport; groundwater transport; integrated soil.groundwater system;

    Abstract : A Lagrangian stochastic travel time approach has been usedfor investigating dominant process impacts on (non-reactive andreactive) solute transport in the integrated soil-groundwatersystem. A first step has also been taken to extending thisLagrangian stochastic travel time approach to integrate thesoil-groundwater-stream transport through a catchment. READ MORE

  7. 20. Population Exposure to Organic Contaminants and Human Biomonitoring

    Author : Erika Norén; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : We are surrounded by various chemicals, both naturally occurring and synthetically produced. Some, but not all, chemicals can be hazardous for human health following exposure, especially for vulnerable population groups including children, adolescents, and pregnant women. READ MORE
