Fuel and fly: adaptations to endurance exercise in migrating birds

Popular Abstract in Swedish Många fåglar flyttar regelbundet långa sträckor mellan sina häckningsplatser och vinterkvarter. På rastningsplatser längs flyttningsvägen stannar fåglarna upp och äter, för att lagra upp de energi-lager de behöver som bränsle när de flyger. Vissa flyttfåglar lägger på sig så mycket bränsle (energi), mestadels som fett, att de dubblar sin kroppsvikt. Det lagrade bränsletBirds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. To minimise the total time spent on migration, birds should fuel up a

Enhancing Knowledge Acquistion Through the use of KMS

An important competitive advantage source for firms in complex, uncertain, and high-velocity environments is their external knowledge-related relationships. Information and communication technologies (ICT) can play an important role in knowledge-intensive processes and flows. Using the dynamic capability and absorptive capability views the paper presents and discusses how ICT can be used to enhanc

A first-principles approach to protein–ligand interaction

It is still impossible to make an accurate, purely theoretical prediction of the free energy of a ligand binding to a protein in aqueous environment. The two main problems are the immense number of nuclear configurations contributing to the binding free energy and the impossibility to apply accurate quantum-chemical methods to such a large system, even for a single configuration. In this thesis, t

Automatic Calibration Procedure for a Robotic Manipulator Force Observer

In this paper, we propose a method for selfcalibration of a robotic manipulator force observer, which fuses information from force sensors and accelerometers in order to estimate the contact force exerted by a manipulator to its environment, by means of active motion. In robotic operation, during contact transition accelerometers and force sensors play a very important role and serve to overcome m
