    Sammanfattning : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. LÄS MER

  4. 13. A stargazer's guide to neurodegeneration : Astrocytes' role in the propagation of pathological proteins

    Författare :Tobias Mothes; Anna Erlandsson; Martin Ingelsson; Linn Streubel-Gallasch; Maria Grazia Spillantini; Uppsala universitet; []
    Nyckelord :Alzheimer’s disease; Parkinson’s disease; tauopathies; astrocyte; microglia; neuron; tau; amyloid-β; α-synuclein; accumulation; degradation; inflammation; spreading; seeding.; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are characterized by brain accumulation of pathogenic protein aggregates. In the AD brain, amyloid-β (Aβ) and tau form plaques respective tangles, while in the PD brain α-synuclein (α-syn) form Lewy bodies and Lewy neurites. LÄS MER

  5. 14. Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem

    Författare :Aminur Rahman; Abul Mandal; Jana Jass; Björn Olsson; Pawel Kaszycki; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy Metals; Pollution; Accumulation; Remediation; Human Health; Bacteria; Genome Sequencing; de novo Assembly; Gene Prediction; Biology; Biologi; Bioteknik;

    Sammanfattning : Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. LÄS MER

  7. 15. Heavy metals in municipal solid waste deposits

    Författare :Peter Flyhammar; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; substrate; transformation; emission; environment; MSW; heavy metals; accumulation; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Extensive use of heavy metals in modern society influences routes followed by fluxes on the surface of the Earth. The changed flow paths may be harmful for the balance of biological systems at different levels, micro-organisms, human beings and whole ecosystems, since the toxicity of heavy metals is determined by their concentrations and chemical forms.
