Fission track analysis (FTA) was developed to be applied to ultra-low levels of 239Pu in bioassay samples. An analytical protocol was established for the FTA processing. The detection limit was determined to 1.5 µBq and the calibration constant was 24 fission fragments per µBq 239Pu. Naturally occuring nuclides of thorium and uranium, present in biological and environmental samples, did not interf

Evaluating SAR for multi-antennas is difficult and impractical due to the arbitrary power allocation and phase of the electric fields from different antennas causing the total field to change randomly. In this context, a simplified approach was recently proposed for assessing SAR when more than one antenna is transmitting simultaneously. The metric of time averaged simultaneous peak SAR (TASPS) wa

To study and simulate cognitive development, it is useful to find a natural domain where many cognitive functions are needed and, but where the complexity of the environment and task is reasonable. We suggest that childrens games constitute a suitable domain. The ability to play is a very fundamental part of children's daily life and it is crucial for the future development of our behaviors in Bek

The software process simulation research field has been growing in recent years. Much effort has been used for developing detailed software process simulation models. However, few studies are available characterizing the effect process simulation models could have when introduced to an organization. Furthermore, most published work in this area has been focused on the effect that the models have f

Popular Abstract in Swedish En amfifil molekyl innebär en molekyl som består av två delar, en som är hydrofil (“vattenälskande”) och en som är hydrofob (“vattenhatande”). Ofta består den amfifila molekylen av en ”vattenälskande” huvudgrupp och en ”vattenhatande” svans och kallas för surfaktant. Detta beteende ger amfifila molekyler speciella egenskaper. En av de viktigaste egenskaperna är att de kIn this thesis temperature induced vesicle formation in both a block copolymer system and nonionic surfactant system have been investigated. The block copolymer is a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), PEO-PPO-PEO, with the average molecular composition of EO5PO68EO5 and the commercial trade name Pluronic L121 (papers I, II). In the L121 system the for

Two-phase flows are commonly found incomponents in energy systems such as evaporators and boilers. Theperformance of these components depends among others on thecontroller. Transient models describing the evaporation process areimportant tools for determining control parameters, and fast loworder models are needed for this purpose. This article describes ageneral moving boundary (MB) model for mod

Female moths emit sex pheromones to lure a mate. In this thesis I examined the transcriptomes of female moth pheromone glands in order to identify genes encoding proteins involved in pheromone production. Two cDNA-libraries were constructed from Agrotis segetum (Noctuidae) pheromone glands and the remaining body tissue, respectively. The libraries were sampled and sequenced. A total of 707 unigene

This work deals with a detailed analysis of the vibrational spectra of methoxy (CH3O-) and ethoxy (CH3CH2O-) on W(110) and Cu(100) single crystal surfaces. By using theoretical ab initio quantum mechanical modeling, it is demonstrated that an unprecedented quantitative understanding of the vibrational frequencies of a surface adsorbate can be obtained. A qualitative understanding of the intensitie

In this paper the problem of sub-optimal sensor schedulingwith a guaranteed distance to optimality is considered. Optimal in thesense that the sequence that minimizes the estimation error covariancematrix for a given time horizon is found. The search is done usingrelaxed dynamic programming. The algorithm is then applied to onesimple second order system and one sixth order model of a fixedmounted

TINA is an open, object oriented, distributed telecom architecture, with many concepts taken directly from the latest computer research. In TINA, instances of the same object type can be placed on different physical nodes. Therefore, the network performance can be improved by introducing load balancing algorithms. These algorithms should distribute the traffic between the object instances in such
