Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. Aerosol particles acting as cloud or ice nuclei can induce a change in cloud properties and thus indirectly induce a change in planetary albedo, which is considered th
Zinc-positive neurons and terminals, known to be associated with the glutamatergic projections in the brain, can be demonstrated by the histochemical Timm method and later modifications thereof. The adult rat neocortex contain a uniform lamination of zinc-positive cells with specific projections to, e.g., the striatum. We have previously reported that fetal neocortical grafts implanted in the adul
We have seen that protein kinase Calpha (PKCalpha) is transiently translocated to the plasma membrane by carbachol stimulation of neuroblastoma cells. This is induced by the Ca2+ increase, and PKCalpha does not respond to diacylglycerol (DAG). The unresponsiveness is dependent on structures in the catalytic domain of PKCalpha. This study was designed to investigate if and how the kinase activity a
I argue along the following lines: For Wollstonecraft, liberty is independence in two different spheres, one presupposing the other. On the one hand, liberty is independence in relation to others, in the sense of not being vulnerable to their whim or arbitrary will. Call this social, or political, liberty. For liberty understood in this way, infringements do not require individual instances of int
Sample treatment is an essential element when using real-time PCR for quantification of pathogens directly on food samples. This study comparatively evaluated three different principles of sample treatment, i.e. immunomagnetic separation based on phage-derived cell wall binding molecules, matrix solubilization and flotation, in order to establish their suitability for quantifying low numbers of St
Putative cellobiose dehydrogenase (CDH) genes are frequently discovered in various fungi by genome sequencing projects. The expression of CDH, an extracellular flavocytochrome, is well studied in white rot basidiomycetes and is attributed to extracellular lignocellulose degradation. CDH has also been reported for plant-pathogenic or saprotrophic ascomycetes, but the molecular and catalytic propert
Identification of the molecule(s) that globally induce a robust regenerative state in sensory neurons following peripheral nerve injury remains elusive. A potential candidate is brain-derived neurotrophic factor (BDNF), the sole neurotrophin upregulated in sensory neurons after peripheral nerve injury. Here we tested the hypothesis that BDNF plays a critical role in the regenerative response of ma
Collagen fibers expose distinct domains allowing for specific interactions with other extracellular matrix proteins and cells. To investigate putative collagen domains that govern integrin alpha(V)beta(3)-mediated cellular interactions with native collagen fibers we took advantage of the streptococcal protein CNE that bound native fibrillar collagens. CNE specifically inhibited alpha(V)beta(3)-dep
Background: Heterogeneous findings have been reported in studies of basal ganglia volumes in schizophrenia patients as compared to healthy controls. The basal ganglia contain dopamine receptors that are known to be involved in schizophrenia pathology and to be vulnerable to pre- and perinatal hypoxic insults. Altered volumes of other brain structures (e.g. hippocampus and lateral ventricles) have
John Kingdon's Multiple Streams Framework (MSF) constitutes a powerful tool for understanding the policy process, and more specifically, agenda-setting, through three separate streams: problems, policies and politics. This article argues that the MSF would benefit from further development of the problem stream. It introduces a clearer conception of agency into the problem stream by suggesting the
Symptoms and signs of the urogenital estrogen deficiency syndrome occur relatively late in a women's life when endogenous estrogen levels are well below those required to stimulate endometrial growth. At age 60 and above symptoms are common and progress with advancing age. The first and most common complaint is vaginal dryness, but symptoms of lost control of micturition as well as urge incontinen
Popular Abstract in Swedish Hur uppfattar predikanter sitt predikouppdrag och hur uppfattar åhörare predikan? Hur förhåller sig dessa uppfattningar till olika predikoteoretiska perspektiv? Vilka konsekvenser får kunskapen om predikanters och åhörares uppfattningar för predikan? I undersökningen kartläggs hur de som är engagerade i predikosituationen tänker om predikan. Två grupper är då särskilt This study describes, systematizes and analyses the variations of preachers' conceptions of their mission to preach and their listeners' conceptions of the sermon. It does so in a phenomenographic and theological perspective. The conceptions of preachers and their listeners of the mission to preach and the sermon respectively are investigated by way of interviews. The basic issues are what differe
Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o
Abstract in Uncoded languages Praegune kaitsejalatsite testimise standard (EN 344) kontrollib soojapidavuslikke omadusi vaid jalatsi ühes punktis, mõõtes temperatuuri muutust. Meetod, mis kasutab termilist jala mudelit, võimaldab mõõta jalatsi soojaisolatsiooni üheaegselt erinevates piirkondades ning ühtlasi ka jalatsi kui terviku soojaisolatsiooni. Selle uurimuse käigus arendati termilise jala mePresent standard on safety footwear (EN 344) checks the insulation only at one point in the shoes by means of measuring the temperature change. A method that uses thermal foot model allows to measure footwear insulation simultaneously at various locations and for whole footwear as well. In the present work the method of heated foot model was developed further. It is possible to simulate sweating a
[1] Convective available potential energy (CAPE), frequently regarded as an indicator of the potential intensity of deep convection, is strongly controlled by the properties of the planetary boundary layer (BL). Variations in CAPE observed during field experiments in midcontinent North America, the tropical east Atlantic, and the tropical west Pacific, can be accounted for mostly by changes in the
Variation of PCO2 with concomitant changes in extracellular pH (pHo) may modulate cerebrovascular resistance, but the direct actions of carbon dioxide and pHo on human cerebral arteries are unknown. In this study, we have evaluated the effects of different carbon dioxide tensions (2.7, 4.2 and 7.2 kPa) with either fixed (pHo = 7.44) or concomitant changes in pHo, on contractions induced by depolar
Oxygen toxicity is thought to be an important factor involved in development of bronchopulmonary dysplasia (BPD) in the very preterm infant. Glutathione (GSH) plays a major role in the antioxidant defense system in the preterm lung and there are theoretical implications that N-acetylcysteine (NAC) treatment could improve its function. The purpose of this study was to investigate whether NAC treatm
Popular Abstract in Swedish FISKETS EFFEKTER BEROR PÅ SAMSPELET MELLAN ARTER Fiske och jakt, så kallad populationsbeskattning, påverkar den fiskade eller jagade populationen på en rad olika sätt. Den direkta effekten är uppenbar: dödligheten ökar, och antalet individer i populationen minskar. I förlängningen påverkar denna minskning också andra arter, som t ex äter eller äts av individerna i den bHarvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment. Species interactions therefore influence the effect of harves
There is an increasing interest in open source, which also goes for enterprise resource planning (ERPs) systems, especially when it comes for small and medium sized enterprises (SMEs). In this article, the focus is on the combination of open source and ERPs, and specifically on what role development of open source ERPs plays in diffusion of ERPs among SMEs. In an effort to be able to explain the i
Abstract Recent years have seen a number of competing theories of concepts within philosophy of mind, supplanting the classical definitionist and imagist accounts: among them, Jerry Fodor's informational atomism, Jesse Prinz's proxytypes theory, and -- of course -- Peter Gärdenfors' (2004) conceptual spaces theory (CST). On the whole there has been little empirical investigation into the competing
