Sustainable Aviation Fuels (SAF) typically exhibit a composition that differs significantly from conventional jet fuels. These variations in chemical makeup influence the thermophysical and reactive properties of these propellants. In this study, Finite-Rate Chemistry (FRC) Large Eddy Simulations (LES) are employed to investigate turbulent spray flames from a Triple Annular Research Swirler (TARS)
Sensory traits shape animal lifestyles due to the central role they play in retrieving and processing environmental information. However, being some of the most energetically expensive tissues to build and maintain, ecological demands often modulate investment in these organs. Evidence that ecology shapes the evolution of sensory traits is plenty but is heavily biased towards vertebrates and has o
Carbon sequestration in arable soils is gaining increasing attention in global policymaking initiatives for climate-change mitigation. Large-scale assessments of soil organic carbon development in arable land are affected by the scarcity of reliable time series of soil organic carbon monitoring data and often fail to replicate observed trends or appreciate any effects induced by changes in soil ma

Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind

Prospective clinical plasma biomarker studies in abdominal aortic aneurysm (AAA) pathogenesis have been hampered by the need for very large cohorts and long follow-up time. The main aim of the present study was to evaluate the association of adrenomedullin, a cardiovascular (CV) stress marker, and incident AAA risk. Prospective longitudinal cohort of middle-aged individuals from the CV cohort of t

The presence of graphite particles in gray cast iron commonly implies a good machinability, especially if compared to common steels. However, increasing industrial demands have resulted in a new interest for high-speed machining of these materials with higher performing tool materials than the traditionally used.

Metastatic melanoma is one of the most common deadly cancers, and robust biomarkers are still needed, e.g. to predict survival and treatment efficiency. Here, protein expression analysis of one hundred eleven melanoma lymph node metastases using high resolution mass spectrometry is coupled with in-depth histopathology analysis, clinical data and genomics profiles. This broad view of protein expres
Arktiska miljöer har de senaste decennierna upplevt en stark temperaturökning, vilket påverkar tundrans kolcykel.Smältande permafrost, minskande snötäcke och förändringar i hydrologiska mönster är exempel på pågående processer som förändrar samspelet mellan mark och atmosfär samt ekosystemens säsongsdynamik.Då ett antal av dessa processer involverar utbyte av växthusgaser, såsom spårgaserna metan Arctic environments have experienced strong warming in recent decades, which is affecting the carbon cycle of tundra ecosystems.Degrading permafrost, diminishing snow cover, and changing hydrology are examples of ongoing processes that affect the land-atmosphere interactions and seasonal ecosystem dynamics.Since a number of the affected processes involve the exchange of atmospheric greenhouse gase
BACKGROUND: Biomarkers reflecting diverse pathophysiological pathways may play an important role in the pathogenesis of abdominal aortic aneurysm (aortic diameter ≥30 mm, AAA), levels of many biomarkers are elevated and correlated to aortic diameter among 65-year-old men undergoing ultrasound (US) screening for AAA.PROBANDS AND METHODS: To evaluate potential relationships between biomarkers and ao
Popular Abstract in Swedish Avhandlingen innehåller ett inledningskapitel följt av fyra separata studier. Studierna behandlar olika aspekter av humankapital, begåvning och immigration. I den första studien, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, används det svenska mönstringstestet för att skatta avkastningen på utbildningen för individer medThis thesis consists of an introductory chapter followed by four separate papers. The papers deal with various aspects of human capital, ability and migration. Using the Swedish Military Enlistment test, the first paper, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, estimates the return to schooling for individuals belonging to different parts of th
Populärvetenskaplig sammanfattning: Denna uppsats är ett examensarbete, utfört som ett Minor Field Studie stipendie i Laos. Uppsatsen behandlar temat avskogning - erosion. Laos är ett land i Sydostasien som gränsar till länderna Thailand, Vietnam, Kambodja, Burma och Kina. 1991 täcktes fortfarande 47 % av landets totala areal av orörda skogar. Laos inriktning mot en marknadsekonomi främjar avverkThe Lao People’s Democratic Republic (Lao PDR) is a small landlocked country in South-East Asia, where virgin forest still covers almost 47 % of the country’s total area (1991). Logging offers the potential to improve the economy of the Lao PDR. Besides legal logging activities, illegal logging to provide the population with agricultural land, pasture and firewood is taking place. Since the Lao PD
Varför väljer utbildare inom FM de utbildningsmetoder de väljer? Vilka faktorer påverkar? Skiljer sig FMs utbildningsmetoder från skolans utbildningsmetoder? Denna studie penetrerar frågorna ur före detta värnpliktigas synvinkel. En litteraturstudie redovisar en jämförelse mellan utbildningsmetoder inom olika utbildningar, inte bara inom skolans värld. En kvantitativ och kvalitativ studie redovisa
BACKGROUND: Kinetic energy (KE) of intracardiac blood flow reflects myocardial work spent on accelerating blood and provides a mechanistic window into diastolic filling dynamics. Diastolic dysfunction may represent an early stage in the development of heart failure (HF). Here we evaluated the hemodynamic effects of impaired diastolic function in subjects with and without HF, testing the hypothesis
Streptococcus pyogenes causes a multitude of local and systemic infections, the most common being pharyngitis in children. Recurrent pharyngeal infections are common and are thought to be due to the re-emergence of intracellular GAS upon completion of antibiotic treatment. The role of colonizing biofilm bacteria in this process is not fully clear. Here, live respiratory epithelial cells were ino
