Solens rörelse

Alla gillar vi att observera världen runtom oss. Vi observerar hur natthimlens stjärnor rör sig från öst mot väst nattetid och vi ser hur Månen ändrar sin position bland stjärnorna från en natt till en annan.I denna interaktiva visning observerar vi Solens rörelse över himlavalvet. Märkte du var den steg över horisonten i morse? Stiger den alltid över horisonten just där? Var kommer solnedgången aWe are all observers of our Universe. We see the stars moving from East to West at night and we see the Moon move among the stars from day to day.But let us consider the Sun. Did you notice where the Sun rose above the horizon this morning? Does it always rise in the same location? Where will the Sun set tonight? Where would it set if we were in Australia?This is an interactive show where we obser

Catchment modelling at the global scale using the World-Wide HYPE (WWH)

Recent advancements in catchment hydrology (such as understanding hydrological processes, accessing new data sources, and refining methods for parameter constraints) make it possible to apply catchment models for ungauged basins over large domains. Here we present a cutting-edge case study applying catchment-modelling techniques at the global scale for the first time. The modelling procedure was c

Speed Responses to Speed Humps as Affected by Time of Day and Light Conditions on a Residential Road with Light-Emitting Diode (LED) Road Lighting

The speed-reducing effect of speed humps during darkness is important to ensure a consistent speed reduction and a decreased probability of accidents during darkness. This study examined the effects of speed humps, compared with a control location, on a residential road in Sweden with light-emitting diode (LED) street lighting and a 30 km/h posted speed limit. Hypotheses tested were that: (I) vehi

Cross-Border Knowledge Flows through R&D FDI: Implications for Low- and Middle-Income Countries

R&D related foreign direct investments represent a powerful mechanism for cross-border knowledge sharing that can stimulate the process of technological catch-up. However, low-income countries and smaller middle-income countries remain largely excluded from this kind of global flows of knowledge. In this chapter, we discuss the motivations and implications of this type of FDI for low and middl

Electron and photon energy calibration with the ATLAS detector using 2015-2016 LHC proton-proton collision data

This paper presents the electron and photon energy calibration obtained with the ATLAS detector using about 36 fb -1 of LHC proton-proton collision data recorded at s=13 TeV in 2015 and 2016. The different calibration steps applied to the data and the optimization of the reconstruction of electron and photon energies are discussed. The absolute energy scale is set using a large sample of Z boson d

Energieffektiv utomhusbelysning längs gångvägar för människor med särskilda behov

Utomhusbelysning i offentliga miljöer har en viktig roll i en hållbar stadsutveckling. Energieffektiv LED-belysning kan stödja mobilitet i stadsmiljöer och medverka till en ökad tillgänglighet för personer med särskilda behov. Belysningen i föreliggande studie upplevdes ge tillräcklig ljusmängd och jämnt ljus, och det gick att se bra i belysningen. Trots att LED-belysningen ökade möjligheterna til

The brown bear population in Scandinavia has substantially increased the last 30 years, in-creasing the probability of interactions between humans and bears. This environmental change is evident to many who live in brown bear areas and to them it is important to feel safe when engaged in nature based activities. This research project aimed to, further develop and evaluate two specific intervention

The use of LIDAR as a data source for digital elevation models : a study of the relationship between the accuracy of digital elevation models and topographical attributes in northern peatlands

It is important to study the factors affecting estimates of wetness since wetness is crucial in climate change studies. The availability of digital elevation models (DEMs) generated with high resolution data is increasing, and their use is expanding. LIDAR earth elevation data have been used to create several DEMs with different resolutions, using various interpolation parameters, in order to comp

I senere tid har spørsmålet om ulvens oppførsel overfor mennesker og nær bebyggelse vært sentralt i diskusjonen om norsk ulveforvaltning. Det har blitt framholdt at en del ulver er nærgående, på den måten at de synes å oppsøke bebodde områder, og ikke viker unna i møte med mennesker. Det sies at nærgående ulver er skremmende, og bidrar til redusert livskvalitet. Denne studiens formål har vært å ka

Metodutveckling för att studera allmänhetens respons på energieffektiv utomhusbelysning

Artificial outdoor lighting for pedestrians should provide for a safe and secure outdoor environment after dark. Pedestrian lighting thereby has implications for active transportation and sustainable mobility. Installations of new energy efficient lighting applications should be evaluated in terms of pedestrian’s perception, evaluation and behaviour in the lit environment. Today there is a lack of

Population and subspecies differentiation in a high latitude breeding wader, the Common Ringed Plover Charadrius hiaticula

Exploring the patterns of genetic structure in the context of geographical andphenotypic variation is important to understand the evolutionary processesinvolved in speciation. We investigated population and subspecies differentiationin the Common Ringed Plover Charadrius hiaticula, a high latitude wader thatbreeds in arctic and temperate zones from northeast Canada across Eurasia tothe Russian Far
