Popular Abstract in Swedish Färger innehåller mer tillförlitlig information än vad bara skillnader i ljusintensitet gör. Det är därför inte svårt att förstå varför de allra flesta landlevande ryggradsdjur har färgseende. Några upplever en färgfattigare värld än vi människor, men många ser fler färgnyanser. På kvällen däremot gör bristen på ljus det svårt att se färger. Trots detta finns det nattakMost terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. However, at night when the light is dim, the lack of photons makes colour vision difficult. Nevertheless, some hawkmoths and bees can se

Det är nedslående att Cecilia Malmström givit upp kampen när det gäller fri- och rättigheter på nätet, skriver politiker och nätdebattörer. Den rättssäkerhet vi efterfrågar är en sådan som skyddar yttrandefriheten.

This paper investigates the association between perinatal health and all-cause mortality for specific age intervals, assessing the contribution of maternal socioeconomic characteristics and the presence of maternal-level confounding. Our study is based on a cohort of 12,564 singletons born between 1915 and 1929 at the Uppsala University Hospital. We fitted Cox regression models to estimate age-var

The EC-Earth earth system model has been recently developed to include the dynamics of vegetation. In its original formulation, vegetation variability is simply operated by the Leaf Area Index (LAI), which affects climate basically by changing the vegetation physiological resistance to evapotranspiration. This coupling has been found to have only a weak effect on the surface climate modeled by EC-

In this paper the spectral features of impulse noise in DSL systems are mapped from the waveform domain onto the symbol domain, considering a QAM receiver. This work can be viewed as part of a full symbol domain model for impulse noise, which should include the amplitude and spectral aspects. Since the available models of impulse noise in DSL are generally waveform-based, this kind of mapping is j

According to film mythology, the Soviet filmmaker Lev Kuleshov conducted an experiment in which he combined a close-up of an actor’s neutral face with three different emotional contexts: happiness, sadness, and hunger. The viewers of the three film sequences reportedly perceived the actor’s face as expressing an emotion congruent with the given context. It is not clear, however, whether or not the

Objective: To determine the importance of antibodies against phosphorylcholine (PC) and oxidized low density lipoprotein (OxLDL) for development of atherosclerosis. Methods and results: Two hundred and twenty six individuals with established hypertension (diastolic pressure > 95 mmHg) were from European Lacidipine Study on Atherosclerosis. Antibodies of IgG and IgM subclass were tested by ELISA ag

The use of amino acids for the synthesis of novel surfactants with vesicle-forming properties potentially enhances the biocompatibility levels needed for a viable alternative to conventional lipid vesicles. In this work, the formation and characterization of catanionic vesicles by newly synthesized lysine- and serine-derived surfactants have been investigated by means of phase behavior mapping and

With the publication of the IPCC Special Report on Carbon dioxide Capture and Storage (CCS), CCS has emerged as a focal issue in international climate diplomacy and energy collaboration. This paper has two goals. The first goal is to map CCS activities in and among various types of intergovernmental organisations; the second goal is to apply International Relations (IR) theories to explain the gro

Kemi är en viktig del i våra dagliga liv och den är fylld med många invecklade processer och mekanismer. Några av oss kanske kommer ihåg tumregeln ”lika löser lika” från kemiundervisningen. Detta påstående stämmer i de flesta sammanhangen inom kemin och kan i vissa fall leda till problem om vi till exempel hade haft smutsig tvätt och enbart hade använt vatten vid rengöringen. När vi använder vat4-Bromo-3-methylaniline was used as the starting block to synthesise a Tröger’s base analogue with the aim of fusing the final monomer into a nanotube. The intermediates were to be characterised using 1H-NMR, 13C-NMR, infrared-, high resolution mass spectrometry, elemental analysis, and X-ray crystallography amongst other. At the end, 356 mg of N-((5R,6S,11R,12S)-8-amino-6,12-bis(methoxymethyl)-1,

Northern Saw-whet Owls (Aegolius acadicus) breed throughout the boreal forest of North America, but little is known about their population trends or distribution within this region. Analysis of stable hydrogen isotopes (delta H-2) in feathers can delineate origins of a variety of avian migrants, but raptors are reported to have high infra-feather isotopic variance and mean delta H-2 values higher
