Karyotype structures of Scenedesmus acuminatus (Lagerch.) Chod. and Scenedesmus pectinatus Meyen are compared. The karyotype of S. acuminatus (n = 5) is described for the first time. It reveals four large metacentric and one large submeta centric chromosomes (4M + 1SM). The established karyotype differences have been helpful in clarifying the taxonomic position of these two species. The cytologica

In this paper, a novel multiple representation data structure for dynamic visualisation of 3D city models, called CityTree, is proposed. To create a CityTree, the ground plans of the buildings are generated and simplified. Then, the buildings are divided into clusters by the road network and one CityTree is created for each cluster. The leaf nodes of the CityTree represent the original 3D objects

The overall aim of this thesis was to analyse the importance of co-morbidity level for different aspects of primary health care (PHC) using a measure of co-morbidity. Paper I examines whether there were differences in referral rates from different Lithuanian PHC models after adjustment for co-morbidity level. Paper II assesses to what extent the co-morbidity level could explain concurrent costs in

The subject of the thesis is the psychê, a Greek word whose closest equivalent is the Swedish “själ”, the English “soul”, the French “âme” and the German “Seele”. The meanings of these words are far from being the same. What is more, the Greek psychê has shifting meanings, both synchronically and diachronically speaking. We are faced with two problems: What does the word psychê designate and how i

In this work we perform a high-resolution spectroscopic investigation of Eu3+-Ce3+ and Pr3+-Ce3+ codoped Y2SiO5 crystals. Satellite line spectra were recorded at low temperatures around the Eu3+:F-7(0) -> D-5(0) and the Pr3+:H-3(4) -> D-1(2) transitions. It is observed that the incorporation of Ce3+ as a codopant notably changes the Eu3+ and Pr3+ satellite line patterns. Satellite lines measured i

The role of not-for-profit organizations (NPOs) and their relationships with various partners within humanitarian aid networks have hitherto been researched only to a limited extent. Formation of interdependencies between actors in humanitarian networks and the implications on societal outcomes require more research. In the nonprofit – for profit domain the former organizations are usually seen as

Combined resistivity and time-domain direct current induced polarization (DCIP) measurements are traditionally carried out with a 50\% duty cycle current waveform, taking the resistivity measurements during the on-time and the IP measurements during the off-time. One drawback with this method is that only half of the acquisition time is available for resistivity and IP measurements, respectively.

Most bees are diurnal, with behaviour that is largely visually mediated, but several groups have made evolutionary shifts to nocturnality, despite having apposition compound eyes unsuited to vision in dim light. We compared the anatomy and optics of the apposition eyes and the ocelli of the nocturnal carpenter bee, Xylocopa tranquebarica, with two sympatric species, the strictly diurnal X. leucoth

The electron-ion scattering experiment ELISe is part of the installations envisaged at the new experimental storage ring at the International Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It offers an unique opportunity to use electrons as probe in investigations of the structure of exotic nuclei. The conceptual design and the scientific challenges of ELISe are presented.

Although the visual flight control strategies of flying insects have evolved to cope with the complexity of the natural world, studies investigating this behaviour have typically been performed indoors using simplified two-dimensional artificial visual stimuli. How well do the results from these studies reflect the natural behaviour of flying insects considering the radical differences in contrast

Despite the importance of both response probability and response time for testing models of choice there is a dearth of chronometric studies examining systematic asymmetries that occur over time- and space-orders in the method of paired comparisons. In this study, systematic asymmetries in discriminating the magnitude of paired visual stimuli are examined by way of log-odds ratios of binary respon

Context and Objective: Intraportal islet transplantation can restore insulin production in type 1 diabetes patients, but its effect is subject to several interfering processes. To assess the influence of beta-cell loss before and during engraftment, we searched for a real-time marker of beta-cell destruction. Previous studies showed that 65-kDa isoform of glutamate decarboxylase (GAD65) is dischar

Power and energy consumption, today essential in all types of systems, can be reduced by scaling the voltage/frequency at runtime and/or powering down idle components. Efficient management requires not only pertinent decisions, but also early access to workload information, as well as domain specific solutions. This paper focuses on runtime energy management for streaming applications running on m

We consider the problem of describing the correlation between two compositions. Using a bicompositional Dirichlet distribution, we calculate a joint correlation coefficient, based on the concept of information gain, between two compositions. Numerical values of the joint correlation coefficient are calculated for compositions of two and three components. We also present an estimator of the joint c

PURPOSE: The use of conformal radiation therapy has grown substantially during the last years since three-dimensional (3D) treatment planning systems with beams-eye-view planning has become commercially available. We studied the degree of conformity reached in clinical routines for some common diagnoses treated at our department by calculating a radiation conformity index (RCI). METHODS AND MATERI

In this longitudinal, prospective, and population-based study (n = 1044), seven BTMs were assessed before and after trauma in 113 elderly women (85 with fractures). Markers were not altered in the immediate postfracture period but were clearly elevated during fracture repair. Recent fracture should thus be taken into account when markers are used in clinical practice.

Popular Abstract in Swedish Lymfom är en grupp tumörsjukdomar som uppkommer från de vita blodkropparna i vårt immunförsvar. Diffust storcelligt B-cellslymfom (DLBCL) är en av de mest aggressiva varianterna av lymfom och uppkommer från den typen av vita blodkroppar som kallas B-celler. Varje år drabbas ca 500 personer i Sverige av DLBCL. Typiska symtom är hastigt tillväxande lymfkörtlar samt viktneDiffuse large B-cell lymphoma (DLBCL) is an aggressive and heterogeneous disease. Identification of prognostic and predictive markers is important to design individualised and effective treatment strategies. This thesis describes different approaches to search for molecular prognostic markers and an attempt to overcome chemotherapy resistance in DLBCL. In the first study it was investigated whet
