Robert Alexy’s theory of legal argumentation is among the notable contributions made to mainstream jurisprudence in the last three decades. Remaining true to its rational discursive mission, it engages with both analytical positivism and natural law theories. A recent collection of essays edited by George Pavlakos explores Alexy’s theory from a number of philosophical standpoints, revealing its th
I tider av krig, hungersnöd eller pandemier har apokalyptiska visioner frodats. Berättelserna var en tidig form av skräcklitteratur som gav konturer åt lidandet och i någon mån gjorde det mer uthärdligt. Men ända in i modern tid har apokalyptiska texter också fungerat som motståndslitteratur mot förtryckare
Denna rapport behandlar den osteologiska analysen av djurbenen från en arkeologisk slutundersökning i fastigheten Öllsjö 67:1 (L1987:3648). Analysen omfattar ben från fem grophus och en härd som daterats till yngre järnålder, med tyngdpunkt på vendeltid. Denna rapport redovisar resultaten från denna analys, samt från två kompletterande 14C-dateringar av ben från två grophus. Analysen har skett ino
Denna rapport behandlar den osteologiska analysen av djurbenen från en arkeologisk slutundersökning av Öllsjö by i fastigheten Öllsjö 6:22, Skepparslövs socken (L1990:5301), år 2002. Analysen omfattar ben från ett gårdsläge daterad till sen vikingatid-tidigmedeltid. Denna rapport redovisar resultaten från denna analys, samt från två kompletterande 14C-dateringar av ben från två grophus. Analysen h
Few germline mutations are known to affect lung cancer risk. We performed analyses of rare variants from 39,146 individuals of European ancestry and investigated gene expression levels in 7,773 samples. We find a large-effect association with an ATM L2307F (rs56009889) mutation in adenocarcinoma for discovery (adjusted Odds Ratio = 8.82, P = 1.18 × 10−15) and replication (adjusted OR = 2.93, P = 2
Foam is one of the unique properties of beer, but how the amphiphilic components stabilize the foam is still not fully understood. This study concerns the main surface active components. For this purpose, protein from barley and iso-humulone from hop, were extracted from raw materials separately to be able to consider their effect separately and in the controlled mixture. The layers were formed in
The heat flux method is advantageous for obtaining adiabatic stretch-less flame and measuring laminar burning velocity, SL, with low uncertainty. However, its implementation is sometimes hampered by the instability, manifested as cellularity of the flame stabilized over a flat perforated burner. This paper summarizes the approaches of flame cellularity abatement on the heat flux burner, which are
Seven skeletal reaction mechanisms are presented to highlight key chemistry for mechanism reduction of small alcohol fuels at engine conditions. The mechanisms predict ignition delay times, laminar burning velocity, and extinction strain rate, within 5% of their corresponding complex mechanisms used as a start point for reduction. The mechanisms were developed for equivalence ratio range of 0.7–1.
Dynamic lighting systems are introduced in urban outdoor environments with the objective to reduce energy use. Effects on pedestrians are not fully known. Previous studies have mainly used observer assessment (Viliunas et al., 2014), and focused on perceived personal safety (Haans & de Kort, 2012) or acceptance (Boomsma & Steg, 2013). In this study, performance (walking speed and reading)
The ongoing transition to renewable fuel sources has led to increased use of wood and other biomass fuels. The physiochemical characteristics of biomass combustion derived aerosols depends on appliances, fuel and operation procedures, and particles generated during incomplete combustion are linked to toxicity. Frequent indoor wood burning is related to severe health problems such as negative effec
Liquid-liquid extraction (LLE) is a useful extraction technique for highly complex samples, however, it suffers from being slow due to mass transfer limitations. Carbon dioxide expanded liquids (CXL) is a good replacement of traditional organic solvents for extraction, and for the first time, the use of CXL in LLE was evaluated. An equipment consisting of a high-pressure view cell with on-line gas
Background: The predominant focus of academic research on the sharing economy has been on Airbnb and Uber; to this extent, the diversity of business models ascribed to the sharing economy has not yet been sufficiently explored. Greater conceptual and empirical research is needed to increase understanding of business models in the sharing economy, particularly attributes that deliver on its purport
Evacuation drills are generally the main mechanism for improving or measuring occupant performance in emergency situations, but their effectiveness is often hard to measure, and there is limited evidence for sustained training benefits. However, innovations in technology (e.g., augmented/virtual reality, novel sensors and wearable tech) offer (when combined with new approaches to designing and del
Brain changes occurring in aging can be indexed by biomarkers. We used cluster analysis to identify subgroups of cognitively unimpaired individuals (n = 99, 64–93 years) with different profiles of the cerebrospinal fluid biomarkers beta amyloid 1–42 (Aβ42), phosphorylated tau (P-tau), total tau, chitinase-3-like protein 1 (YKL-40), fatty acid binding protein 3 (FABP3), and neurofilament light (NFL
‘Flight shame’ describes an unease about the climate implications of air travel, and bears evidence of a change in social norms that have so far associated flying with social status. This paper discusses whether Fridays for Future demonstrations and ensuing flight shame have influenced social norms regarding the desirability of air travel, and whether this is measurable in a decline in air travel,
The removal of micropollutants from municipal wastewater is challenged by the number of compounds with diverse physico-chemical properties. Ozonation is increasingly used to remove micropollutants from wastewater. However, ozonation does not necessarily result in complete mineralization of the organic micropollutants but rather transforms them into new compounds which could be persistent or have a
