A small population of Primula elatior has recently been found in a virgin swampy forest close to the southeastern shore of lake Ringsjon in Stehag parish. Here it grows in fully natural vegetation together with e.g. Anemone ranunculoides, Paris quadrifolia, Listera ovata, Ranunculus auricomus and Viola epipsila and there are no reasons to suspect that the population is anything but spontaneous. Un

To every analytic function $g$ in the unit disk $\bold D$ one associates the integral operator $T_g(f)(z)\coloneq z^{-1}\int^z_0f(\xi)g'(\xi)d\xi$ on spaces of analytic functions in $\bold D$. Operators of this form appear naturally in complex analysis. For instance, the choice $g(z)\equiv z$ leads to the integration operator, and the choice $g(z)=\log(1/(1-z))$ leads to the Cesàro operator. The

Ontological analysis facilitates microarray data interpretation. We describe new ontological analysis methods which, unlike existing approaches, are threshold-free and statistically powerful. We perform extensive evaluations and introduce a new concept, detection spectra, to characterize methods. We show that different ontological analysis methods exhibit distinct detection spectra, and that it is

One and a half years after the implementation of the ISPS code in Swedish ports there is still much work to be done. Port security covers so much more than technical and instrumental issues. The manners in which perceptions of threat are defined and constructed are also of central importance in understanding the rationale of working with port security. Alongside with the development of regulations

In order to trace the origin and evolution of carbon in the Galactic disc, we have determined carbon abundances in 51 nearby F and G dwarf stars. The sample is divided into two kinematically distinct subsamples with 35 and 16 stars that are representative of the Galactic thin and thick discs, respectively. The analysis is based on spectral synthesis of the forbidden [C I] line at 872.7 nm using sp

Incubation of 3T3-L1 preadipocytes with isobutylmethylxanthine (IBMX), dexamethasone, and insulin, alone or in combination, demonstrated that IBMX, which increased cAMP-response element-binding protein (CREB) phosphorylation, was the predominant regulator of Pde3b expression. Real time PCR and immunoblotting indicated that in 3T3-L1 preadipocytes, IBMX-stimulated induction of Pde3b mRNA and protei

This article proposes nonparametric inference procedures for analyzing microarray gene expression data that are reliable, robust, and simple to implement. They are conceptually transparent and require no special-purpose software. The analysis begins by normalizing gene expression data in a unique way. The resulting adjusted observations consist of gene-treatment interaction terms ( representing di

Glycoprotein B (gB) is a major component in several vaccines that are under development for prevention of disease by cytomegalovirus. It contains multiple determinants that are targets for neutralizing antibodies. One of them is site I of antigenic domain 2 (AD-2). The epitope, defined by short peptides, is quite conserved between different isolates. However, it is poorly immunogenic in natural in

Two-dimensional resistivity imaging using multiple gradient, Wenner and dipole-dipole electrode arrays was carried out at two field sites in Sweden and one in Nicaragua, with the objective of confirming the practical applicability of results obtained with numerical modelling. The results support earlier numerical modelling studies that concluded that the gradient array, using multiple current elec

The dynamic crack growth in ductile steel is investigated by means of the impact loaded 3 point bending (3PB) specimens. Results from experiments and numerical simulations are compared to each other. A modified 3PB specimen designed with the reduced width at its ends has been developed in order to avoid the initial compressive loading of the crack tip and also to avoid the uncertain boundary condi

Levels of messenger RNAs for brain-derived neurotrophic factor, nerve growth factor and neurotrophin-3, and their high-affinity receptors, TrkB and TrkC, were analysed in the brains of genetically fast and slow kindling rats using in situ hybridization. Basal expression of neurotrophins and Trk messenger RNAs in the hippocampal formation, amygdala, frontoparietal and piriform cortices did not diff

NK cells have been associated with immune surveillance of tumor cells and defense mechanisms against various pathogens. However, by their capacity for immunoregulation NK cells may also play a role in determining the response to allergens. The novel possibility that NK cell activity may in part decide development of allergic airway inflammation and thus potentially be involved in the inception of

Previous studies identified serine, cysteine and metalloproteases in normal aqueous humours (AH) and suggested that a balance between proteases and their inhibitors may play a role in the modulation of the AH outflow. We aimed to determine whether secretory leukocyte protease inhibitor (SLPI), a serine protease inhibitor, is present in AH of patients with cataract and other eye pathologies. AH was

Tissue firmness and stiffness are functions of tissue and cell wall structure, water status and temperature, and their interactions. This investigation elaborates the physiological basics of temperature and water status effects on firmness of fresh intact carrots and radish tubers. The results can add to a better understanding of the mechanical properties at least of these succulent plant storage

• The ability of the nematode-trapping fungus Arthrobotrys oligospora and the nematode egg parasite Verticillium chlamydosporium to colonize barley (Hordeum vulgare) and tomato (Lycopersicum esculentum) roots was examined, together with capability of the fungi to induce cell wall modifications in root cells. • Chemotropism was studied using an agar plate technique. Root colonization was investiga

Objective. The present experimental study explored pathomorphological changes and calcium depositions in the tympanic membrane during experimental acute otitis media caused by nontypeable Haemophilus influenzae in myringotomized and nonmyringotomized ears. Material and methods. A rat model of experimental acute otitis media caused by nontypeable Haemophilus influenzae was employed Sixteen Sprague-

Design. In a longitudinal study, 335 children ages 8, 11 and 14, first studied in 1989 were followed-up on two occasions in 1991 and 2002. The subjects filled in questionnaires on pain, the first two times in school, the last as a postal survey. Purposes. To determine if headache and back pain during the school years were transitory or if they grew into pain problems in adulthood; to determine pre

During endurance flight most birds do not feed and have to rely on their body reserves. Fat and protein is catabolised to meet the high energetic demands. Even though the hormonal regulation of migration is complex and not yet fully understood. the adrenocortical hormone corticosterone crystallizes to play a major role in controlling physiological traits in migratory birds during flight. However,
