Filetype
The holotype (KUVP 1301) of Styxosaurus snowii—one of the earliest described elasmosaurid plesiosaurians—consists of a well-preserved cranium, mandible and articulated sequence of anterior–mid-series cervical vertebrae found in the lowermost Campanian strata of the Smoky Hill Chalk Member in the Niobrara Formation of Kansas, USA. This particular specimen has proven important for recent phylogenies
Popular Abstract in Swedish Ta ett djupt andetag och tänk på vad du nu har i lungorna! Jo, det är luft, förstås, syre kväve och sådant. Men det är också något annat. I varje kubikcentimeter du andas in finns tusentals partiklar, alla för små för att kunna ses med blotta ögat. Om dessa partiklar handlar denna avhandling. Vi kallar luftburna partiklar för aerosoler, ett begrepp som innefattar allt Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. The concern about health effects have during the last decade shifted towards fine and ultrafine particles, not least due to the emerging f
Twelve years ago, eleven European countries voluntarily abandoned their home currencies and joined the Euro. The founding fathers of the Euro believed that creation of the common currency would strengthen integration among the members and catalyze economic convergence progress within the common currency area. This study examines this issue in detail. I focus on labor productivity convergence and s
This paper seeks to provide insight on the status and fertility of e-voting as a leveling agent in the municipalities of Haparanda and Botkyrka, which has the lowest voter turnout in Sweden. Through quantitative surveys in the townships, and further interviewing the development manager of the Swedish election committee. The collected material on e-voting was tested on parts of the rational choice
In a VUCA world, characterized by complex, unpredictable, ambiguous and rapidly changing conditions, organizations and their managers are constantly faced with interpreting and responding to disruption. While research has investigated how disruption can be navigated, the perspective of how individual managers more concretely navigate disruption remains comparatively underexplored. The purpose
Atrial fibrillation (AF) is the most common heart rhythm abnormality and is a leading cause of heart failure and stroke. This large-scale meta-analysis of genome-wide association studies increased the power to detect single-nucleotide variant associations and found more than 350 AF-associated genetic loci. We identified candidate genes related to muscle contractility, cardiac muscle development an
Background: Sport-related concussion (SRC) is a common and complex injury in athletic populations. Linear head acceleration (LHA) and rotational head acceleration (RHA) are key biomechanical factors believed to contribute to SRC, each through distinct mechanisms. Evaluating head impact magnitudes across different sports, athlete populations, and measurement methods is essential for advancing SRC
A new model; WORLD6 was developed. WORLD6 differs from the earlier system dynamics world models in several aspects. Several modules link the economy, materials, metals, energy, population and politics in a dynamic system. The present version is a result of a dismantling of the World3 model (Meadows et al., 1972, 1992, 2004) with an extension and substitution of its resource module and economy modu
Purpose: Today’s chemical society use and emit an enormous number of different, potentially ecotoxic, chemicals to the environment. The vast majority of substances do not have characterisation factors describing their ecotoxicity potential. A first stage, high throughput, screening tool is needed for prioritisation of which substances need further measures. Methods: USEtox characterisation factors
Modified ZYMO DNA/RNA miniprep extraction protocol written in a user friendly way to reduce in-process-decisions and process time. Sample type is organic soil, peat, from a degraded rich fenThis protocol includes two modifications to tackle clogged filters. Samples were centrifuged for 45 seconds instead of 30 seconds in first pass through filters as 100 ul to 200 ul sample remained trapped above
This contribution aims to identify and clarify emotional aspects of conducting observation studies. The researcher, in most cases, does not want to interfere with or influence the phenomenon under observation, but uses her/himself as a tool to collect material. Even if the observer does not participate verbally, s/he can be emotionally participative using her/his emotions as a methodological tool,
One of the most important travelers of the 18th century was Jakob Jonas Björnståhl. From a young age, he aspired to reach prominence in academic circles. Greek, Latin, and various Middle Eastern languages were part of his studies from the outset, and he distinguished himself by his enthusiasm, thirst for knowledge, and ability to quickly master diverse subjects, along with his encyclopedic educati
Recording and analysing groundwater level data can reveal the nature and extension of groundwater processes like flow direction and recharge magnitude. The analyses can even indicate the influence of precipitation, evapotranspiration and runoff on the subsurface processes. However, such analyses are only possible when the recorded data cover relatively large periods of time at a suitable frequency
Using several melanoma proteomics data sets we created a single analysis platform that enables the discovery, knowledge build, and validation of diagnostic, predictive, and prognostic biomarkers at the protein level. Quantitative mass-spectrometry-based proteomic data was obtained from five independent cohorts, including 489 tissue samples from 394 patients with accompanying clinical metadata. We
The transformation of complex spatial and temporal patterns into mapped and recorded archaeological data requires archaeologists to translate temporally non-distinct processes of exploration into a series of visual recordings of distinct moment of discovery. These visual records, produced by articulating key moments in the excavation process as cleaned and documentable contexts and finds, form a cThe transformation of complex spatial and temporal patterns into mapped and recordedarchaeological data requires archaeologists to translate temporally non-distinct processes ofexploration into a series of visual recordings of distinct moment of discovery.

AbstractRecent research in the wider archaeological landscape of Great Zimbabwe recovered moreevidence of metallurgical tuyeres fused in varied multiples indicative of their use in natural draft iron smelting technologies. We report the first detailed chemical, microstructural and thermal analyses of these ceramic materials most likely associated with large-scale iron production at the zenith of tWe report the first detailed chemical, microstructural and thermal analyses of a growing corpus of metallurgical tuyeres from the wider archaeological landscape of Great Zimbabwe in southern Africa. Of note is the fusion of the tuyeres in multiples, suggestive of widespread use of natural draft iron smelting technologies for large-scale production of iron most likely during the zenith period of Gr
