Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. Their migration range is at least I km, and we found no clear wind-borne pattern

Gene fusion in protein engineering : design of novel peptides and bifunctional enzymes

The gene fusion technique is widely used in protein engineering and in this thesis it constitutes the basis of both the construction of artificial bifunctional enzymes and the display of two novel peptides. Artificial bifunctional enzymes have been used as model systems in the studies of native multifunctional enzymes and proximity effects within these complexes. Two various constructs are descri

Exposure-Based Cash-Flow-at Risk for Value Creating Risk Management under Macroeconomic Uncertainty

A strategically minded CFO will realize that strategic corporate risk management is about finding the right balance between risk prevention and proactive value generation. Efficient risk and performance management requires adequate assessment of risk and risk exposures on the one hand and performance on the other. Properly designed, a risk measure should provide information on to what extend the f

Site investigation with combined methods in a faulted area in Managua, Nicaragua - a pre-study

Geophysical methods are increasingly being applied to geotechnical investigations, as they can identify material properties and material boundaries, as well as variations in space and time of relatively large volumes of soil. Another advantage is that many of these methods are non-intrusive. The combination of several methods and the verification of their results by sampling and correlating with g

Postural Control in Single-limb Stance. In Individuals with Anterior Cruciate Ligament Injury and Uninjured Controls

Popular Abstract in Swedish Skador i knäleden är vanligt förekommande bland unga fysiskt aktiva personer. I västvärlden drabbas årligen ca 1 per 1000 invånare av skada i knät. I ungefär en tredjedel av dessa knäskador drabbas främre korsbandet. I samband med främre korsbandsskada, är det vanligt med skador på menisker, kollateralligament och brosk. Ruptur av främre korsbandet, med eller utan andraThe overall aims of this work were to evaluate a method of assessing postural control, measured by balance in single-limb stance on a force platform, and to study balance in single-limb stance in individuals with non-operated anterior cruciate ligament (ACL) injury in comparison with that of uninjured controls. Ninety-nine patients (99) with ACL injury and 141 uninjured subjects were included in

Approximation of Infinitely Divisible Random Variables with Application to the Simulation of Stochastic Processes

This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. So in practice the higher order methods required at least the same amount of work as the Euler method to obtain

Physical Characterization of Actinide Particles - A Study on Novel Techniques for Radiological and Nuclear Safeguard Investigations

This thesis presents a study of advanced analytical techniques, for the characterization of actinide particles originating from the non-peaceful use of nuclear technology and from international inspections of the nuclear fuel cycle associated with non-proliferation agreements. The thesis is based on five papers, which will be referred to by Paper I-V in the text. Individual particle analysis has s
