Popular Abstract in Swedish Många beständighetsproblem uppträder i gränsytor mellan material. Exempel är lossfrysning av puts på tegel, avflagning av färg, sprickbildning hos ytskikt, vidhäftningsbrott mellan reparationsmaterial och underlag. I nästan alla fall är nedbrytningen kopplad till alltför höga fuktnivåer i gränsytan. Flera beständighetsproblem, t.ex. frostnedbrytning, uppstår enbart om mThe main impetus for this research was the desire to verify models for determining transient moisture profiles in the capillary range. For the evaluations, transient moisture profiles were both simulated and measured, after which the results of the two methods were compared. The study was performed for on specimens exposed to continuous water absorption, using specimens of both single and combined

Popular Abstract in Swedish Avhandlingen handlar om ett område i hjärnan som kallas amygdala. Detta området är ansvarigt för att lära sig vad man bör tycka om och vad man skall vara rädd för. I avhandlingen diskuteras hur det här området verkar fungera, och hur det arbetar tillsammans med andra områden för att göra sitt jobb. Dessa reaktioner är primitiva känslor; rädsla, lycka och så vidare. AvhaThe amygdala is a small subcortical structure that has long been implicated in the conditioning of fear and other emotions. It is heavily interconnected to a number of both cortical and subcortical structures and is thus well placed to integrate sensory inputs from multiple areas to produce emotional reactions directly as well as influence learning and attention systems. Data suggests that the amy

Popular Abstract in Swedish Förståelse av väldigt snabba proceeser i molekyler utgör grunden inom modern kemi. Jonisation och excitation av en molekyl med en foton startar en nukleär dynamisk process som åtföljs av elektroniskt sönderfall och fragmentering av molekylen. En rörelsemändsvektor-spektrometer har utveclats som används för att mäta massa, laddning, energi och hastighet av joniska fragmeA momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. The possibility of focusing is essential for most applications, where fragment momentum is to be extracted. The apparatus

The very first data from MAX-lab in Lund, Sweden on pion photoproduction at threshold energies are presented. The decrease of the total π+ yield in γ+12C, 27Al reactions below 200 MeV as well as the dσ/dΩ cross-section data essentially follow the predictions of an intranuclear-cascade model with an attractive potential for the pion–nucleus interaction. However, View the MathML source, cross-sectio

This article picks up on a term (‘cross-fertilisation’) often exploited in debates on the interaction of international laws and legal practices, especially in the context of international criminal law. Two questions are addressed: (1) What is the meaning of ‘cross-fertilisation’? (2) What are its conditions? As the article argues, ‘cross-fertilisation’ pertains to the understanding of legal uttera

A positive correlation between virus evolutionary rate and disease progression has been shown for human immunodeficiency virus type 1 (HIV-1) infection. Much less is known about HIV-2, the second causative agent of AIDS. We analyzed 528 HIV-2 env V1-C3 sequences generated from longitudinal plasma samples that were collected from 16 study participants during a median observation time of 7.9 years (

Cerebral palsy is the commonest cause of severe childhood disability, the aetiology of which is largely unknown. Data on familial aggregation of cerebral palsy are very limited. We defined familial risks for siblings who were hospitalised because of cerebral palsy in Sweden. A nationwide database for neurological diseases was constructed by linking the Multigeneration Register to the Hospital Disc

Studies have indicated that transportation noise is associated with higher cardiovascular mortality, whereas evidence of noise as a risk factor for respiratory and cancer mortality is scarce and inconclusive. Also, knowledge on effects of low-level noise on mortality is very limited. We aimed to investigate associations between road and railway noise and natural-cause and cause-specific mortality

This thesis explores the impact of female social media entrepreneurs (SMEs) on the entrepreneurial aspirations of young female adults. Using a qualitative research approach, the study employs an exploratory, abductive research design and semi-structured interviews to gain a deeper understanding of how social media entrepreneurs encourage entrepreneurial aspirations of young female adults. Social m

Background: Preterm birth has been shown to cause various long-term health issues. Children who were born preterm have also been observed to have more dental behaviour management problems (DBMP) during dental examinations and treatment than children born full term. It is known that dental radiographic examinations can be uncomfortable and cause anxiety in paediatric patients. Thus, our aims were t

Background: Older adults are underrepresented in suicide prevention research, even though suicide rates are higher in this age group (65+) than in any other age group in many countries worldwide. There are few clinical intervention studies that target this age group. A promising preventive intervention is the Attempted Suicide Short Intervention Program (ASSIP). Given differences in suicidal behav

Detta arbetet har hanterat sex olika borrkärnor från den Prekambriska berggrunden i Ohio, USA. Denna berggrund är täckt med 800 – 5000 meter av Paleozoiska avlagringar och på grund av detta vet vi väldigt lite om den. Arbetet har gått ut på att karakterisera och datera dessa bergarter samt att via isotop analyser av syre och hafnium ta reda på bergarternas sammansättning och evolution. BorrkärnoThe Grenville orogen forms a major, continental scale, Mesoproterozoic orogenic belt along the present day eastern North American continent, from Labrador in the north to Mexico in the south. It is, however, mainly exposed in the northeastern parts of North America. Most of the orogen forms a basement to thick piles of Phanerozoic sedimentary rocks, and the geological evolution of the extensive co

Forty alkaliphiles, which were isolated from samples collected in Eastern Africa, have been screened for production of antibacterial compounds. One of these isolates, Bacillus halodurans B20, was able to produce a prominent amount of antibacterial activity against a Gram-positive bacteria on agar plates [paper I] and selected for further study. Production of the active compound in submerged culti

Ethiopia achieved a remarkable episode of agricultural intensification from the mid-1990s to the late-2010s, yet the political mechanisms that enabled this transformation—and the distributional and environmental consequences that followed—remain insufficiently understood. This article ex- amines how political leadership, understood in institutional rather than personalistic terms, shaped both the

Background: Neuropsychiatric symptoms (NPS) are very common in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia and are associated with various disadvantageous clinical outcomes including a negative impact on quality of life, caregiver burden, and accelerated disease progression. Despite growing evidence of the efficacy of (non)pharmacological interventions to re

Increasingly, scholarly debates and policy developments on citizen participation in energy transitions have included calls for ‘energy democracy’ and active forms of ‘energy citizenship’. The concepts are tightly connected to the debate on energy transition, and the need for a decentralised energy system, based on renewable energy and increased local energy ownership. The two concepts exist in par

Background: Up-to-date epidemiological stroke studies are important for healthcare planning and evaluating prevention strategies. This population-based study investigates temporal trends in stroke incidence and case-fatality in southern Sweden. Methods: First-ever stroke cases in the local catchment area of Skåne University Hospital in Lund, Sweden, between March, 2015 and February, 2016, were inc
