  1. 1. Odor perception in three Coleoptera: molecule, receptor & neuron

    Författare :Jonas Bengtsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, the sense of olfaction and its links to behavior was studied in the cetoniid chafers Pachnoda interrupta and P. marginata, and the bark beetle Ips typographus. P. interrupta is a pest on sorghum in Ethiopia, and I. LÄS MER

  3. 2. Stopover Ecology of Mallards : Where, when and how to do what?

    Författare :Daniel Bengtsson; Jonas Waldenström; W. Michael Eichholtz; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Age characters; body condition; departure decision; effects of influenza A virus; habitat selection; mallard; movement; Ottenby Bird Observatory; stopover ecology; weather; wild birds; Ecology; Ekologi;

    Sammanfattning : The mallard (Anas platyrhynchos) is the most numerous and widespread duck in the northern hemisphere and a model species in ecology and harvest management. Migration is a crucial life stage for many birds and understanding the drivers of migration has important implications for conservation biology and assessment of animal population responses to global changes.

  4. 3. Negative symptoms, repetitive transcranial magnetic stimulation and heart rate variability in schizophrenia and depression

    Författare :Johan Bengtsson; Robert Bodén; Jonas Persson; Erik Olsson; Caroline Wass; Jimmi Nielsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; negative symptoms; psychotic disorders; affective disorders; non-invasive brain stimulation; transdiagnostics; psychometrics; autonomic nervous system; Psychiatry; Psykiatri;

    Sammanfattning : Negative symptoms comprise anhedonia, avolition, and blunted affect. Although first described in schizophrenia, these symptoms share phenomenology with the depressive state. Pharmacological treatment has not been successful in reducing negative symptoms. LÄS MER

  5. 4. Increasing the value of household appliances by adding a heat pump system

    Författare :Peder Bengtsson; Jonas Berghel; Tomas Persson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat pump; Appliances; ASKO; Energy system; Energiteknik; Energy Technology;

    Sammanfattning : Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. LÄS MER

  7. 5. Phenomena in wire based multi-layer laser welding and hybrid deposition

    Författare :Jonas Näsström; Alexander Kaplan; Frank Brueckner; Sven Bengtsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : Several laser materials processing technologies using metal wire addition have been researched during the last decades. Especially in the field of joining, as well as in the field of Additive Manufacturing (AM), multiple major benefits have been reached, e.g. higher welding speeds and lower heat input. LÄS MER
