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

Phosphorus (P) is a critical macronutrient for plant growth, often limiting plant production in areas where plant demand is higher than soil supply. In contrast to nitrogen (N), P cannot be sourced from the atmosphere; therefore, where it is rare, it becomes a strong constraint on primary production. Due to this, most dynamic global vegetation models (DGVMs) are incorporating a prognostic P cycle

The user services assistant (USA) is a novel reactive QoS agent that provides facilities for managing user to user QoS in Internet environments. By being reactive, it overcomes the problems associated with QoS management schemes that have been proposed to date, such as the mapping of the QoS parameters to end system parameters, and pre-determining the optimum way of degrading/upgrading the QoS. Ho

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.

Field bio-remediation techniques (FBRT) can be a low cost method to avoid the removal of top layers of soil which are rich in organic matter and bio diversity. The use of native microorganisms in FBRT is preferable because non-indigenous species can transfer their genetic material to the environment with negative impacts on the local ecological equilibrium. Petroleum Produced Water (PPW) is an imp

We find that CO ligates selectively to nitrogen tetra-coordinated Co(i) single metal atom sites at room temperature in a manganese–cobalt bi-metallic coordination network self-assembled on graphene. The bound state is metastable, determined by pressure-dependent equilibrium conditions between adsorption and desorption, with an upright, end-on bonding geometry (binding energy 0.73 eV). The ligand v

Analysing datasets from hunting statistics and human cases of tick-borne encephalitis (TBE), we found a positive correlation between the number of human TBE cases and the number of red fox (Vulpes vulpes). Time lags were also present, indicating that high numbers of red fox in 1 y translated into high numbers of human TBE cases the following y. Results for smaller predators were mixed and inconsis

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

The effect of shallow water table fluctuations on the evaporation and CO2 fluxes in a peatland is investigated. The fluxes of evaporation and net ecosystem exchange of carbon were measured from mid-spring to the end of summer in 2005 and 2006 and simulated independently with process models. The observed and modelled data were then compared along a gradient of water levels. Any variation along the

Recent experiments at the CELSIUS storage ring of Uppsala, Sweden, have revealed the existence of high momentum transfer target-like fragments contrary to expectations. Recoiling heavy fragments in the reaction of 250 MCV/nucleon N-14 on Xe-131 have been measured at 10degrees with respect to the beam direction with specially designed recoil telescopes, Simulations with the Boltzmann-Uehling-Uhlenb
