The main function of a membrane is to control the exchange of matter between the surrounding regions. As such, accurate modeling of membranes is important to properly describe their properties. In many cases in both biological systems and technical applications, the membranes are composite structures where transport properties may vary between the different sub-regions of the membrane. In this wor
This work is focused on synthesis, characterization, and determination of main parameters of the multilayer P123 templated TiO2 films. The mesoporous multilayer thin films consist of TiO2 nanoparticles on the F-doped SnO2 (FTO) conductive glass substrates. The films were grown by implementing the protocol of supramolecular templating with the amphiphilic triblock copolymer, Pluronic P123. The temp
The diversity and community composition of moths (both macro- and micromoths) at 32 sites, representing a wide range of habitat types (forests, grasslands, wetlands, agricultural and urban areas) within a restricted region in central Scania,southern-most Sweden, was investigated by use of light moth traps and compared with vascular plant species richness and habitat characteristics. The results re
Neurocognitive disorder encompasses many separate diagnoses, such as frontotemporal dementia (FTD), Alzheimer's disease (AD), Lewy body dementia (LBD), vascular dementia (VaD), and mixed dementia (MD). Because of the many variations between and within each subtype, it may be a challenge to clinically diagnose each condition. In a previous study on 176 dementia patients in a university hospital coh
The establishment of introduced species in new environments is today widely acknowledged as a potential threat to biodiversity, and many plants that are known to be invasive have obviously spread from gardens. Thus, in the context of biosecurity, we need to consider how contemporary gardeners think about which plants and animals are welcome in their gardens. In this chapter we look at vegetation i
Popular Abstract in Swedish Bukspottkörteln (pankreas) består av en exocrin och en endocrin del. Den exocrina delen som studerats i denna avhandling innerhåller acinarceller som producerar bukspott innehållande matsmältningsenzymer. Dessa enzymer spjälkar proteiner, kolhydrater och fetter som finns i födan, till sina mindre beståndsdelar aminosyror, monosackarider och fettsyror. Efter sekretion avThe regulation of the exocrine pancreas has been under thorough investigation for many decades. In rats, cholecystokinin (CCK) is considered to be the major gut hormone stimulating the pancreas to releasing the digestive enzymes. CCK acts directly via CCK-A receptors in the pancreas, or through receptors located on the vagal afferents and stimulating the secretion via the cholinergic vagal efferen
The Cognitive Interview (CI) is a well-researched interview method and the research results show that CI, compared with more conventional interview styles, enhances witnesses’ memory. However, not much research has been done on the question of how CI affects the realism of eyewitnesses’ judgments of confidence in the veracity of their interview statements. In a previous study (Granhag, Jonsson &am
Natural habitats are rapidly declining due to urbanisation, with a concomitant decline in biodiversity in highly urbanised areas. Yet thousands of different species have colonised urban environments. These organisms are exposed to novel urban conditions, which are sometimes beneficial, but most often challenging, such as increased ambient temperature, chemicals, noise and light pollution, dietary
1. Carbon monoxide (CO), produced by haem oxygenase through degradation of haem, has been claimed to be a neuromessenger and a possible regulator of vascular tone. We examined whether the haem oxygenase inhibitor, zinc protoporphyrin-IX (ZnPP) and other porphyrins affect the relaxation evoked by various agents in the rat isolated aorta. 2. Pretreatment with ZnPP (0.1 mM) virtually abolished the re
Pseudomonas aeruginosa is 1 of the bacteria most adaptive to anti-bacterial treatment. Previous studies have shown nosocomial spread and transmission of clonal strains of P. aeruginosa in European hospitals. In this study we investigated antibiotic susceptibility and clonality in 101 P. aeruginosa isolates from 88 patients admitted to 8 Swedish ICUs during 2002. We also compared phenotypes and gen
Insect herbivores are important drivers of ecosystem processes in grasslands, and can mediate the grassland's response to environmental change. For example, recent evidence shows that above‐ and belowground herbivory, individually and in combination, can modify how a plant community responds to nitrogen (N) eutrophication, an important driver of global change. However, knowledge about how such eff
In this paper I discuss the challenge of visualising ongoing and repeated state violence and impunity in Thailand. Human rights activists commonly assume that photographs hold political power. This assumption can be doubted. Even if there are material traces of the violence, they cannot guarantee visibility, and, as Ariella Azoulay points out, photography of violence risks depoliticizing by equati
Hemorrhagic transformation (HT) is a complication of severe ischemic stroke after revascularization. Patients with low platelet counts do not receive reperfusion therapies due to high risk of HT. The immunomodulatory drug fingolimod attenuated HT after tissue plasminogen activator in a thromboembolic stroke model, but the underlying mechanism is unknown. Fingolimod acts on several sphingosine-1-ph
Context. The dynamics of a low-mass protoplanet accreting solids is influenced by the heating torque, which was found to suppress inward migration in protoplanetary disks with constant opacities. Aims. We investigate the differences in the heating torque between disks with constant and temperature-dependent opacities. Methods. Interactions of a super-Earth-sized protoplanet with the gas disk are e
The role of neuropeptide FF (NPFF) and its analogs in pain modulation is ambiguous. Although NPFF was first characterized as an antiopioid peptide, both antinociceptive and pronociceptive effects have been reported, depending on the route of administration. Currently, two NPFF receptors, termed FF1 and FF2, have been identified and cloned, but their roles in pain modulation remain elusive because
We performed spatially resolved near-ambient-pressure photoemission spectromicroscopy on graphene-coated copper in operando under oxidation conditions in an oxygen atmosphere (0.1 mbar). We investigated regions with bare copper and areas covered with mono- and bi-layer graphene flakes, in isobaric and isothermal experiments. The key method in this work is the combination of spatial and chemical re
Population ageing is putting pressure on pension systems and health care services, creating an imperative to extend working lives. At the same time, policy makers throughout Europe and North America emphasize home care. Thus, the number of people combining caregiving responsibilities with paid work is growing. We investigate the conflicts that arise from this by exploring the time costs of unpaid
