The dolphin-like ichthyosaurs – also known as ‘fish lizards’ – are extinct marine reptiles that roamed the Mesozoic oceans for some 160 million years. As for most ancient vertebrates, our knowledge of these iconic animals largely derives from biomineralized hard parts (teeth and bones). However, soft tissues are also known from a number of Lagerstätte specimens, and have opened up new avenues for

We also present the articles included in the issue, which all explore aspects of how critical performativity and alternative organization may
Alzheimer’s Disease (AD), a neurodegenerative disease, defined by abnormal accumulation of proteins, both extracellularly (senile plaques, consisting of amyloid-beta(Aβ) accumulation) and intracellularly (neurofibrillary tangles, formed by Tau protein). Several studies demonstrate that the immune cells play a central role in the pathogenesis of AD, but it is not known if immune cells from the peri
This study aims to contribute towards the existing literature of volunteer tourism by evaluating the impacts that volunteering has on career progression. There exists a plethora of research on volunteer tourism, focusing on the various motivations to volunteer and the diverse positive and negative impacts that volunteering has on host communities. However, there is less research on the impact it h
Abstrakt Bakgrund: Distriktssköterskan har en nyckelroll i arbetet på vårdcentral och ett framstående ansvar och uppdrag. I ansvaret ingår att arbetat hälsofrämjande, personcentrerat och även att ha en ledande roll att utveckla omvårdnaden utifrån folkhälsoperspektiv. Den berörda problematiken som belyses av aktuell forskning och hälsomyndigheter är att ohälsosamma levnadsvanor medför stor sjukdo
Digital platforms is an innovation made possible by the adoption of computers and internet. Companies like Google and Facebook grew in relatively short time to the most valuable or-ganisations on the stock market. The success of these companies is partially possible by their characteristics of being a digital platforms. One of the success factors is the use open APIs, which makes that other partie
Fotbindning praktiserades i Kina under nästan tusen år. Under Qingdynastins sista turbulenta årtionden öppnades landet upp mot omvärlden. Detta markerade inledningen på Kinas moderna historia, och en ny era för de kinesiska kvinnorna och deras fötter. Denna uppsats undersöker antifotbindningsrörelsen som växte fram i slutet av 1800-talet, mot bakgrund av en ökad västerländsk närvaro och spirande kFootbinding was widely practiced in China for nearly a thousand years. The Middle Kingdom was opened to the outside world during the last decades of Qing rule. This time of turmoil marked the beginning of modern Chinese history, as well as a new era for Chinese women and their feet. This thesis highlights the antifootbinding movement that emerged at the end of the 19th century and its connection t
För att undersöka barns fulla förståelse av ords betydelser är det nödvändigt att undersöka förståelse av ord i relation till andra ord. Antonymi, motsatsrelationen, är en av de semantiska relationer som barnet tillägnar sig tidigast i språkutvecklingen. Syftet med studien var att undersöka förskolebarns förmåga till motsatsordsmobilisering, det vill säga förmågan att välja rätt motsatsord som res
Objective. In systemic sclerosis (SSc; scleroderma), T cells infiltrate organs undergoing fibrotic changes and may participate in dysregulated production of collagen by fibroblasts. The objective of this study was to functionally characterize T cells infiltrating skin lesions in early SSc and investigate their capacity to affect production of type I collagen and interstitial collagenase (matrix me
Three novel tetracyclic terpenoids, of which two possess potent cytotoxic activities towards various mammalian cell lines, were isolated front extracts of the fermentation broth of the ascomycete Dasayscyphus niveus. The structures of the compounds, named dasyscyphins A-C, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.
The degradation of live plant biomass in fungus gardens of leaf-cutting ants is poorly characterised but fundamental for understanding the mutual advantages and efficiency of this obligate nutritional symbiosis. Controversies about the extent to which the garden-symbiont Leucocoprinus gongylophorus degrades cellulose have hampered our understanding of the selection forces that induced large scale
BACKGROUND: We compared the association of levosimendan or dobutamine with norepinephrine for the maintenance of systemic and hepatosplanchnic perfusion during early endotoxemic shock. METHODS: Twenty anesthetized pigs (26.8 +/- 0.5 kg) were instrumented with flow probes and catheters to monitor systemic and regional perfusion as described in our companion article in this issue of the journal. Two
This study examined how root growth and morphology were affected by variation in soil moisture at four Amazon rainforest sites with contrasting vegetation and soil types. Mean annual site root mass, length and surface area growth ranged between 3-7 t ha(-1), 2-4 km m(-2) and 8-12 m(2) m(-2) respectively. Mean site specific root length and surface area varied between 8-10 km kg(-1) stop and 24-34 m
The unimolecular chemiluminescent decomposition of unsubstituted dioxetanone was studied at the complete active space self-consistent field level of theory combined with the multistate second-order multiconfigurational perturbation theory energy correction. The calculations revealed interesting features. Two transition states, two conical intersections, and one intermediate stable biradical struct
The aim of the study is to research preschool teacher’s understanding and way of talking about ethnicity and diversity in two different municipalities. The design of the methods performed for the study was qualitative and seven interviews have been done to gather empirics. The interview guide was semi-structured in order to be able to keep a flexible approach through the interviews. The result sho
Världen över ställs stater inför ett växande cyberhot och antalet mellanstatliga cyberoperationer har ökat markant. Idag är inte enbart datorer och mobiltelefoner beroende av en uppkoppling utan även transaktioner, pacemakers, bilar, flygplan och otaliga tillbehör i vår vardag. Därutöver styrs en stor del av samhällets infrastruktur såsom sjukhus, banker och energisektorn av särskilda informationsAround the world states are facing a growing cyber threat and the number of intergovernmental cyberoperations is significantly increased. Today, not only computers and mobile phones are dependent on a connection, even transactions, pacemakers, cars, airplanes and innumerable accessories in our daily lives depend upon it. Furthermore, a considerable part of society’s infrastructure, like hospitals,
Denna studie syftar till att studera ordaccenter hos barn i förskoleålder med skånsk dialekt och språkstörning. I studien undersöks huruvida barnen har problem med ordaccenterna och i vilken utsträckning. Barnens yttranden bedöms perceptuellt av två lyssnargrupper och akustiskt som spektrogram, där jag tittat på grundtonskurvan. Svar söks också kring huruvida vissa ord är svårare att bedöma eller
