Popular Abstract in Swedish Familjen Mosasauridae omfattar en grupp storvuxna (3-13 m), vattenlevande reptiler som under ett geologiskt sett kort tidsavsnitt i kritperioden, om ca 25 miljoner år, snabbt tog över positionen som topp-predatorer i haven. Fossil av mosasaurier dyker först upp i lager avsatta för ca 90 miljoner år sedan. Under de följande årmiljonerna fick gruppen en närmast global utbMarine strata of latest early Campanian age (sensu germanico) in the Kristianstad Basin, Skåne (Scania), southern Sweden, have yielded a diverse mosasaur fauna comprising six to eight taxa, including Tylosaurus ivoensis, Clidastes propython, Hainosaurus minor n. sp., Halisaurus sternbergii, Platecarpus cf. somenensis, Platecarpus? sp., Dollosaurus sp., and possibly yet another mosasaurine or halis

BACKGROUND: Knowledge on the reinnervation of transplanted organs is scarce, and the aim of the study was therefore to evaluate to what degree syngeneic pancreas grafts were reinnervated in rats. METHODS: Syngeneic pancreatico-duodenal transplantations were performed in normoglycemic Wistar-Furth rats. Native and transplanted pancreas and duodenum were removed 4 or 40 weeks after implantation, and

The cerebrovascular lesions of severe chronic hypertension were studied by light microscopy in perfusion-fixed, subserially sectioned brains from stroke-prone spontaneously hypertensive rats (SHRSP). The leakage and spread of plasma proteins were visualized by immunohistochemical detection of extravasated fibrinogen and by using an exogenous marker (Evans blue injected i.v.) for blood-brain barrie

Popular Abstract in Swedish En mängd epidemiologiska studier har visat att fuktskador i bostaden eller på arbetsplatsen ökar risken för olika typer av hälsobesvär, t.ex. astmatiska och allergiska besvär. Exakt vad som emitteras och orsakar dessa symptom i fuktskadade byggnader är inte känt, men både kemiska och mikrobiologiska agens är misstänkta. Vidare finns behov av bättre metoder för att identIt has been shown in a large number of scientific studies that living or working in a building with mould and moisture damage increases the risk for asthmatic and allergic symptoms. However, there is a need to establish more valid methods to obtain a more nuanced picture of the wide range of different types of moisture related problems. Furthermore, the causal relationships and the biological mech

Purpose: Recently, there has been a growing interest in operating medical linear accelerators without a flattening filter Due to reduced scatter, leaf transmission and radiation head leakage a reduction of out-of-field dose is expected for flattening filter free beams. The aim of the present study was to determine the impact of unflattened beams on peripheral dose for advanced treatment techniques

The influence of aerosols, both natural and anthropogenic, remains a major area of uncertainty when predicting the properties and behaviour of clouds and their influence on climate. In an attempt to better understand warm cloud formation in a tropical marine environment, a period of intensive measurements took place in December 2004 in Puerto Rico, using some of the latest developments in online i

Protoplanetary disks are the natural by-product of star formation and the sites of planet formation. Initially, they are composed of the gas and small solids they inherit from the molecular cloud they form in. The interactions between this material is complex and understanding their details is key for a complete picture of planet formation. The planet formation process begins with growth form abo

III-V semiconductor nanowires are high aspect ratio nanostructures with superior properties that can potentially enhance the functionality of next-generation opto-electronic devices. At present, the most reliable method for fabricating III-V semiconductor nanowires is the particle-assisted vapor-liquid-solid growth using a substrate-based growth process. However, a substrate-based process limits t

Objectives To describe the prevalence of comorbidities in a population referred to standardised first-line intervention (patient education and exercise) for hip and knee osteoarthritis (OA), in comparison with the general population. Furthermore, we aimed to evaluate if eventual differences were associated with socioeconomic inequalities. Design Register-based study. Setting Primary healthcare, Sw

Background: OncoMasTR is a new multigene prognostic test that was discovered via a novel transcriptional network analysis method that identified upstream Master Transcription Regulators (MTRs), which regulate previously identified prognostic biomarkers. The optimised OncoMasTR signature incorporating clinicopathological information has been shown to be significantly prognostic for predicting dista

This thesis is based on work done by the author on the development of plasma-based electron accelerators driven by ultra-intense laser pulses and dense electron bunches. Plasma based accelerators have several benefits, such as accelerating fields around 1000 times stronger than in “conventional” radio-frequency accelerators, which can allow for shrinking the overall footprint of the accelerator. T

The Upper Paraná River Basin (UPRB) has undergone extensive Land Use and Cover Changes (LUCC) in thelatest decades, due to rapid population growth and economic development. Furthermore, variation in precipitationpatterns was observed across the basin mainly after the 1970s Climate shift. Concurrently, the UPRB has presentedsignificant changes in its hydrology. In this context, this thesis investig

Popular Abstract in Swedish Rovdjur påverkar strukturen och artsammansättningen i de flesta system. Både genom att äta upp bytesdjur och genom att inducera olika typer av försvar hos bytesdjuret kan rovdjur påverka andra organismer i systemet. Att undvika att bli upptäckt, och därmed sannolikt uppäten, av ett rovdjur är grundläggande för fortlevnaden hos alla bytesdjur. Under utvecklingens gång haPredator released chemical cues provide a valuable source of information to prey organisms that can be used to alter their behaviour in order to reduce predation risk. In this thesis, I have examined under what circumstances chemical cues may be used by prey, and if prey discriminate between different cues. I have also investigated the role of predator experience in prey ability to detect and resp

Introduction: There is a common understanding that driving under the influence of alcohol is associated with higher risk of being involved in crashes with injuries and possible fatalities as the outcome. Various countermeasures have therefore from time to time been taken by the authorities to prevent drunk driving. One of them has been the alcohol interlock. Up to now, interlocks have mainly been

Disturbances of interatrial conduction are linked to supraventricular arrhythmias. Previous studies have shown that these disturbances can be detected non-invasively as distinctive appearances of the orthogonal P wave using signal-averaged P-wave analysis (PSAECG). Orthogonal recordings (VCG) are however scarce in clinical practice for practical reasons. The aim of the presented study was to explo

The primary (acute) haemosporidian infection has the greatest negative effect on an individual’s fitness. Weak individuals are most likely eliminated from the population, while those that survive, develop a chronic infection when parasite infection intensity is kept at low levels with minor effects on the condition of the host’s life history traits. It is still unknown whether low levels of haemos

Interimistiska säkerhetsåtgärder är en viktig komponent i internationella skiljeförfaranden. Emellertid är institutet förenat med en rad oklarheter. Ett sådant element är de regelverk som reglerar beviljandet av interimistiska säkerhetsåtgärder meddelade av skiljemän. Vilka förutsättningar som ska vara uppfyllda för att en skiljenämnd ska bevilja säkerhetsåtgärder är inte fastställt, och olika tilThe institute of interim measures is an integral component in international commercial arbitration. However, there are uncertainties in terms of the procedural aspects of these measures. One pertinent issue is the legal frameworks that govern the granting of arbitral interim measures. The matter of what substantive standards and requirements to apply on requests for interim measures is unresolved,

Coastal areas around the world are being shaped by many natural phenomena, as well as by man-induced activities. Hydrodynamic phenomena such as wind-generated waves, extreme storms and seasonal tides cause a continued change in topography and the natural sediment formation in the nearshore zone as a result of erosion and accumulation. Therefore, the nature of the nearshore zone and its protection

Offentlig samverkan är vanligt förekommande i Sverige, framförallt inom den kommunala sektorn. För att kommuner och landsting ska kunna leva upp till de offentligrättsliga krav som ställs är det ofta en nödvändig förutsättning att de utbyter tjänster med varandra. Ett problem som ofta uppstår vid sådana tjänsteutbyten är att samarbetsavtalet utgör ett upphandlingspliktigt kontrakt enligt reglerna Public-public cooperation is common in Sweden, particularly in the municipal sector. In order for municipalities and county councils to live up to the requirements of public law, it is often a prerequisite for them to exchange services with each other. A problem often encountered in such exchanges of services is that the cooperation agreement is related to the laws of public procurement. The legis
