  1. 21. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

    Författare :Xin Niu; Yifang Ban; Paolo Gamba; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RADARSAT-2; spaceborne; polarimetric SAR; urban land cover; classification; Information technology; Informationsteknik;

    Sammanfattning : Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use.

  3. 22. Is water a crucial factor in the oxidation of FeCrAl alloys?

    Författare :Helena Josefsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpha-Al203; oxidation kinetics; high temperatur corrosion; reactive elements; FeCrAl; vater vapour; transient alumina;

    Sammanfattning : FeCrAl alloys are much used at high temperatures because the formation of a dense and slow-growing alumina scale provides resistance towards oxidation and high temperature corrosion. While the FeCrAl alloys are primarily intended for temperatures above 950ºC, they are sometimes used at lower temperature, for example as supports in automotive catalysts. LÄS MER

  4. 23. Physical functioning in old age : temporal trends and geographical variation in Sweden

    Författare :Britt-Marie Sjölund; Eva von Strauss; Högskolan i Gävle; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADL disability;

    Sammanfattning : ADL disability is an age-related condition that leads to poor quality of life, increased health-related care costs, and increased mortality. The proportion of older adults are increasing worldwide, and it is therefore important both for society and the individual that research provide us with information about the process leading to ADL disability and how to identify persons at risk.

  5. 24. How does O+ outflow vary with solar wind conditions?

    Författare :Audrey Schillings; Hans Nilsson; Rikard Slapak; Lars-Göran Westerberg; Christopher Cully; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric science;

    Sammanfattning : The entire solar system including Earth is enveloped in a region of space where the Sun’s magnetic field dominates, this region is called the heliosphere. Due to this position in the heliosphere, a strong coupling exists between the Sun and our planet. LÄS MER

  7. 25. Wnt signalling in the development of ventral midbrain dopaminergic neurons

    Författare :Gonçalo de Sá e Sousa de Castelo-Branco; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dopaminergic Neuron; Ventral Midbrain Development; Writs; Dickkopf; beta-catenin; GSK-3beta; Stem Cells; Neural Precursors;

    Sammanfattning : Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson's disease (PD). Proof-of-principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources. LÄS MER
