  1. 21. Estimating source area of pollen and pollen productivity in the cultural landscapes of southern Sweden - developing a palynological tool for quantifying past plant cover

    Författare :Anna Broström; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerial photographs; pollen productivity estimates; relevant source area of pollen; southern Sweden; quantitative landscape reconstruction; GIS; pollen dispersal; simulation model; Geology; physical geography; Geologi; fysisk geografi;

    Sammanfattning : Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. LÄS MER

  3. 22. Investigation of the structural response of pavements in cold region using instrumented test site data

    Författare :Denis Saliko; Sigurdur Erlingsson; Pauli Kolisoja; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexible pavement; environmental impact; seasonal variation; heavy loading; non-destructive testing; instrumented section; Flexibla vägkonstruktioner; Omgivningspåverkan; Säsongvariation; Tung trafikbelastning; Oförstörande provning; Instrumenterade teststräckor; Byggvetenskap; Civil and Architectural Engineering; Building Materials; Byggnadsmaterial;

    Sammanfattning : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. LÄS MER

  4. 23. Model-Based Hypothesis Testing in Biomedicine : How Systems Biology Can Drive the Growth of Scientific Knowledge

    Författare :Rikard Johansson; Gunnar Cedersund; Tomas Strömberg; Peter Strålfors; Marija Cvijovic; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems biology; modeling; ODE; hypothesis testing; falsificationism; insulin signaling; yeast; population heterogeneity; cell-to-cell variation; facilitation; pyramidal; synaptic; bootstrapping; personalized medicine; omics;

    Sammanfattning : The utilization of mathematical tools within biology and medicine has traditionally been less widespread compared to other hard sciences, such as physics and chemistry. However, an increased need for tools such as data processing, bioinformatics, statistics, and mathematical modeling, have emerged due to advancements during the last decades. LÄS MER

  5. 24. Temperature- and body size scaling: effects on individuals, populations and food webs

    Författare :Max Lindmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Climate warming impacts organisms directly through changes in their physiology. Empirical evidence suggest warming has already led to changes in growth, body size, population and community size-structure of natural populations. However, it is difficult to understand the underlying mechanisms from observational data alone. LÄS MER

  7. 25. Omnivore population dynamics and trophic behavior : applications for sustainable willow short rotation coppice

    Författare :Anna-Sara Liman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant traits can mediate the interactions between plant feeding trophic omnivores and their herbivore prey via density effects and by altering the omnivore’s trophic behavior (plant vs. prey feeding). LÄS MER
