  1. 1. Treeline dynamics in short and long term perspectives observational and historical evidence from the southern Swedish Scandes

    University dissertation from Sundsvall : Department of Natural Sciences

    Author : Lisa Öberg; Mittuniversitetet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Betula pubescens ssp. czerepanovii; Picea abies; Pinus sylvestris; climate change; monitoring; treeline advance; clones; megafossils; immigration; Holocene; cryptic refugia; Swedish Scandes; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Terrestrial ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Terrestrisk ekologi;

    Abstract : Against the background of past, recent and future climate change, the present thesis addresses elevational shifts of alpine treelines in the Swedish Scandes. By definition, treeline refers to the elevation (m a.s.l. READ MORE

  2. 2. Analysis of Sun-Damaged Skin and Epidermal p53 Clones

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helena Bäckvall; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Patologi; MEDICINE Morphology; cell biology; pathology Pathology; MEDICIN Morfologi; cellbiologi; patologi Patologi; Pathology; patologi;

    Abstract : Sun-damaged skin is a relevant target tissue for studying the development of skin cancer. The aim of the present study was to investigate the epidermal response to ultraviolet radiation (UVR) in human skin in vivo and in vitro and to explore the mutagenic effect of UVA. READ MORE

  3. 3. Impact and control of weeds in biomass willow clones

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johannes Albertsson; Sveriges lantbruksuniversitet.; [2014]

    Abstract : Willow (Salix spp.) grown on arable land as short-rotation coppice (SRC) produces renewable energy in the form of woody biomass. This perennial crop has a high ratio of energy output to input and a good environmental profile. However, weed control is mostly dependent on herbicide use. READ MORE

  4. 4. Strong Partial Clones and the Complexity of Constraint Satisfaction Problems Limitations and Applications

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Victor Lagerkvist; Linköpings universitet.; Linköpings universitet.; [2016]

    Abstract : In this thesis we study the worst-case time complexity of the constraint satisfaction problem parameterized by a constraint language (CSP(S)), which is the problem of determining whether a conjunctive formula over S has a model. To study the complexity of CSP(S) we borrow methods from universal algebra. READ MORE

  5. 5. Structure and Activity of Circular Plant Proteins Cytotoxic Effects of Viola Cyclotides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Herrmann; Uppsala universitet.; [2007]
    Keywords : Pharmacognosy; cyclotide; cytotoxic; anti-tumour; macrocyclic; cyclic cystine knot; Alpine violet; Sweet violet; Viola; Violaceae; chemical modifications; structure-activity studies; mass spectroscopy; cDNA clones; Farmakognosi;

    Abstract : Cyclotides are a family of small and macrocyclic proteins that have been found in Violacaee and Rubiaceae plant species. These proteins contain a cystine knot: two disulfides bonds together with their connecting peptide backbone form an embedded ring which is penetrated by a third disulfide bond. READ MORE
