Painting Treatments of Weather-Exposed Ferrous Heritage. Exploration of Oil Varnish Paints and Painting Skills
(2021-10-15)This thesis is about industrial heritage—the protection of ferrous heritage by using anticorrosive oil varnish paints. The purpose of this thesis in Kulturvård and craft research is to provide guidelines, tools, concepts, ... -
Paleolimnological reconstructions of fish population changes in acidified lakes
(2011-03-04)This thesis deals with the potential of using subfossil Chaoborus spp. and Daphnia spp. remains preserved in lake sediments to reveal past fish community alterations related to progressive acidification. Sediment cores ... -
Pallsoffa i maj
(Hantverkslaboratoriet, 2013)Vad kan man göra med gamla lastpallar? Jo, en trädgårdssoffa till exempel. Här visas hur det går till. En film av och med Frode Falkenhaug. Filmen gjordes på Hantverkslaboratoriets kortkurs i dokumentär filmteknik för ... -

Parasite host interaction between the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) – the impact from glochidia larvae on the host
(2022-02-17)Parasites can modulate the physiology and behavior of the hosts to enhance their chances to complete their life cycle. The numerous freshwater bivalves of the order Unionoida all have a parasitic larval stage, also known ... -
Paternal care and brood reduction in a pipefish
(2012-11-01)From an evolutionary and adaptive perspective, the occurrence and extent of parental care in animals (investment in offspring beyond the genetic contribution) is expected to depend on an optimal (fitness-maximizing) balance ... -
Patterns of evolution in a young species, the Baltic seaweed Fucus radicans
(2015-04-29)To be able to interpret patterns of biodiversity it is important to understand the processes by which new species evolve and how closely related species remain reproductively isolated and ecologically differentiated. This ... -
Percolation: Inference and Applications in Hydrology
(2011-11-25)Percolation theory is a branch of probability theory describing connectedness in a stochastic network. The connectedness of a percolation process is governed by a few, typically one or two, parameters. A central theme ... -
Periodized Thermal Greens Functions and Applications
(2013-08-30)This work describes a new formalism for Fermionic thermal Greens functions that are discretized in imaginary time. The discretization makes the thermal Greens function periodic in imaginary (Matsubara) frequency space and ... -
Peroxiredoxins in Redox Signaling and Aging
(2017-10-23)Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not ... -
Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors
(2017-11-06)Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food ... -
Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB
(2014-04-08)Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait ... -
Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord
(2012-11-29)The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture ... -
Photocatalysis beyond conventional precious metal complexes
(2022-11-08)Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. The mining of these metal ores is ... -
Photoredox catalysis harnessing oxygen-centered radicals
(2023-04-04)Visible light provides an abundant and renewable source of energy with an ample capacity to mediate chemical transformations. Photoredox catalysis utilizes this energy for the generation of high-energy radical intermediates ... -
Phylogenetic and phyloclimatic inference of the evolution of Potentilleae (Rosaseae)
(2010-05-20)Polyploidization has occurred many times during the evolution of angiosperms. Allopolyploidization is believed to be the process behind many of these genome duplications, and has resulted in a genetically diverse angiosperm ... -
Phylogenetic Inference and Allopolyploid Speciation - A Study of Silene section Physolychnis
(2012-08-31)The major theme of this thesis is allopolyploidization, with focus on Silene section Physolychnis. The evolutionary history of an allopolyploid species can be established by inferring the sister relationships of the ... -
Phylogenetic Relationships, Biogeography and Species Delimitation: A case study on southern African Silene (Caryophyllaceae)
(2023-09-20)The primary aim of this thesis was to explore the phylogenetic relationships and historical biogeography of African members of the plant genus Silene (Caryophyllaceae), with special focus on the eight native southern African ... -
Phylogeny and biogeography of the plant family Calceolariaceae
(2010-11-26)Calceolaria L., Jovellana Ruiz & Pav., and Porodittia G. Don (=Stemotria Wettst. & Harms) toghether constitute the family Calceolariaceae consisting of approximately 300 species distributed manily in South America. The ... -
Phylogeny and Signal Diversity in Widowbirds and Bishops (Euplectes spp.)
(2010-02-19)Although sexual selection for elaborate signals is well documented in numerous species, the extreme diversity in signal design and expression in many taxa is largely unexplained. This thesis explores phylogenetic, mechanistic ...
