1. 16. The movement pattern of horse and rider in different degrees of collection

   Författare :Anna Byström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : While some degree of collection is considered as basic schooling work for the riding horse, learning to perform the most collected movements, such as piaffe and passage, can be a performance limiting factor for dressage horses. The aim of this thesis was to study biomechanics of horse-rider interaction in varying degrees of collection. LÄS MER

3. 17. Topological band theory and Majorana fermions : With focus on self-consistent lattice models

   Författare :Kristofer Björnson; Annica M. Black-Schaffer; Jonas Fransson; Olle Eriksson; Andrei Bernevig; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Topology; Majorana; superconductivity; material physics; numerical calculations; tight-binding; mean-field;

   Sammanfattning : One of the most central concepts in condensed matter physics is the electronic band structure. Although band theory was established more than 80 years ago, recent developments have led to new insights that are formulated in the framework of topological band theory. LÄS MER

4. 18. Alterations in circadian entrainment : translational value in major depression

   Författare :Frederik Elberling; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Adverse conditions of different origin occurring during development can have a negative impact on the nervous system and increase risk for the onset of mental disorders. In mice prenatal exposure to excess glucocorticoids (GC) leads to late onset depression-like behaviour in males which is preceded by alterations in circadian entrainment. LÄS MER

5. 19. Coral reefs in a human-dominated environment : implications of altered disturbance regimes and reduced resilience

   Författare :Magnus Nyström; Terry Done; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Korallrev; Ekosystem i vatten; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : Coral reefs are facing an "Anthropocene " era where humans have advanced from a minor species with limited influence on coral reefs to a major source of disturbance. Disturbance arriving from human influences may not only interact with each other, but also with natural disturbance regimes, leading to synergistic effects. LÄS MER

7. 20. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

   Författare :Kristin Persson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

   Sammanfattning : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. LÄS MER
