    Sammanfattning : Children’s early mathematics learning and development have become a topic of increasing interest over the past decade since early mathematical knowledge and skills have been shown to be a strong predictor of later mathematics performance. Understanding how children develop mathematical knowledge and skills and how they can be supported in their early learning could thus prove to be a vital component in promoting learning of more formal mathematics.

  3. 2. Conservation of saproxylic species : an evaluation of set-asides and substrates in boreal forests

    Författare :Line Djupström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forest management has altered the prerequisite of many species in forest landscapes. The new, more conservation-oriented forest management includes a range of different strategies that aim to prevent losses of biodiversity. LÄS MER

  4. 3. A pathway for pleasant touch: linking peripheral receptors to central processing and hedonic experience

    Författare :Line Sofie Löken; Göteborgs universitet; []
    Nyckelord :pleasant; touch; microneurography; human; CT afferent; unmyelinated;

    Sammanfattning : This thesis investigates the mechanisms underpinning pleasant touch, describes a pathway from peripheral nerve endings in the skin to the insular cortex, and relates these findings to the subjective hedonic experience of touch. In Paper I, the relationship between primary afferent encoding and perception of pleasantness was investigated by combining microneurography recordings from human mechanoreceptors with psychophysical measurements during soft brush stroking at 6 different velocities between 0.

  5. 4. Fouling in biomass fired boilers

    Författare :Jan Sandberg; Rebei Fdhila; Erik Dahlqvist; Alain Liné; Mälardalens högskola; []
    Nyckelord :Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : This thesis describes a detailed investigation into fouling in biomass fired boilers according to fuel mixture, combustion conditions, transportation of particles by the flue gas and the probability of particles impinging and sticking onto heat transfer tubes. The effects of fouling on overall boiler performance and the efficacy of soot blowing are also investigated. LÄS MER

  7. 5. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Författare :Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Nyckelord :smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. LÄS MER
