1. 1. Context dependency of plant – animal interactions

   Författare :Malin A. E. König; Johan Ehrlén; Christer Wiklund; John Stinchcombe; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anthocharis cardamines; attack intensity; Cardamine pratensis; cytotype; herbivory; larval fitness; oviposition; phenology; plant-animal interactions; plant resistance; plant tolerance; polyploidy; spatial variation; trait variation; Plant Ecology; växtekologi;

   Sammanfattning : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. LÄS MER

   Sammanfattning : In 2017 alone, an estimated 68,851 people lost their lives as a consequence of civil wars, that is, armed conflicts that take place within the borders of a state. Such violent conflicts not only lead to immense human suffering, but also leave social, economic and political imprints on the societies that experience them. LÄS MER

5. 4. Respiratory burst and severity of demyelinating diseases

   Författare :Natalia Mossberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurologi; immunologi; Guillain-Barré; Multiple sclerosis; respiratory burst;

   Sammanfattning : Multiple sclerosis (MS) and the Guillain-Barré syndrome (GBS) are tissue-specific inflammatory diseases of the central and the peripheral nervous system, respectively. A contemporary analysis infers that these are complex autoimmune disorders. LÄS MER

7. 5. On initiation of chemically assisted crack growth and crack propagation paths of branching cracks in polycarbonate

   Författare :Ulf Hejman; Malmö högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; stress corrosion cracking; polycarbonate; dissolution; branching; experiment; finite element modelling; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; branching.;

   Sammanfattning : Stress corrosion, SC, in some cases gives rise to stress corrosion cracking, SCC, which differs from purely stress intensity driven cracks in many aspects. They initiate and grow under the influence of an aggressive environment in a stressed substrate. They grow at low load and may branch. LÄS MER
